Title: Mix-Pre 3/6 USB Batteries (what works and what doesn't)
Post by: Fatah Ruark (aka MIKE B) on June 03, 2017, 05:51:50 PM
So I did some more testing with the USB batteries with the MP6 and I have and found some interesting results. I haven't done any run times on these, but will try to today (or soon).

I purchased a Anker PowerCore 20100 to use with this. It (sort of) works. Details on what I have below (and what happens when I use it with my MP6):

1. Anker PowerCore 20100 (https://www.amazon.com/gp/product/B00X5RV14Y/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1): Powers the unit with a FULL GREEN USB power bar. I get a very brief (1ms) flash that says USB-C Power is low warning. Also get this if I unplug one of the USB-A sides. It seems to work fine since I have the AA's in there to fail back to, but very annoying to have the warning flash every few seconds. This unit claims to output 2.4amps on each USB output. Maybe I got a bad battery. Anyone have this issue with this battery?

2. Jackery Giant+ Premium 12,000 mAh Dual (https://www.amazon.com/Jackery-Premium-Portable-External-Panasonic/dp/B00AANQLRI?th=1). Powers the unit with ORANGE USB power bar. This unit claims to output 2.1amps on 1 USB / 1A on the other USB. I wouldn't use this unless I was desperate.

3. Tecknet iEP390 (http://www.tecknetonline.com/download/User_Manual/IEP390_User_Manual.pdf). Amazingly this seems to work the best. Powers the unit with a FULL GREEN USB power bar. Unfortunately it's no longer available to buy. Capacity is 9000mAh. This unit claims to output 2.1amps on 1 USB / 1A on the other.


On paper #1 seems like it there should be no issues...and the MP6 records audio with no issues with this battery.

On paper #3 should be the worst...but it works the best. Another bonus...it's small and fits in my bag easily. 9000mAh should get me though any normal show.

I'd really like to find a USB-C battery where I can just use 1 single USB-C to USB-C cable.

I can see why SD isn't making a list of "approved" USB batteries. The #'s on these things don't seem to add up.

So...feel free to add to the list. What do you have that is working for you and what doesn't.

Here's the only list with an approved USB battery
https://www.sounddevices.com/tech-notes/mixpre-3-mixpre-6-powering-options

And here's the battery

Unfortunately I believe it comes with a USB a to USB c cable so you have to buy a c>c seperately

The powercore 20100 says 4.8 output and the powercore + says 6
I wonder since the plus model is approved by SD that the extra output juice is required for full functionality.
The batteries seem the same with exception to the total output power

Actually it is 2.4 A for the 20100 and 3A for the + model. So the + model delivers 15W (5Vx3A) that the Mix Pre 3/6 seem to require.

My conclusion is the best route is to use a battery equipped with USB-c output and a USB-c to USB-c cable. The optional AC power supply delivers 5v @ 3Amps (15 watts), which is what the USB-c Anker battery they suggest outputs. This probably is what the unit would like to see.


I bought one of these for testing

https://www.monoprice.com/product?p_id=16240

Output 2: USB-C 5V/3A



SD says the unit need 7.5 watts 5v x 1.5 amps) - this is probably the minimum needed.

The limiting factor with using a USB-c to USB-A cable and  USB-A centric battery appears to me to be the cable. These cables must be limiting amperage to .9 - 1 amp. I was also under the impression USB batteries could output 2.1-2.4 but only some cables will actually pass this through. The dual USB-a cable gets around this by doubling the amperage. I ran tonight with both USB-a end connected to the same battery and did not get warnings and have a full green plug.

Ted found two USB-C to USB-A cables that work with his current batteries. These must pass through the full amperage.  As far as I an tell this goes against the safety precautions that should be a USB-A to USB-c cable but these cables also have downwards USB-c connectors and are very appealing fro ma cable point of view

Pro-Sound (NYC) is a distributor for the UK based Hawk-Woods company.  I sent Hawk-Woods a message asking about other USA distributors for these two SD approved Hawk-Woods products for the new MixPre 3/6 series.  I also sent Pro-Sound a message inquiring on pricing for the above two items.  I purchased my Aeta 4MinX from Justin @ Pro-Sound.  Unfortunately Justin no longer works there.

http://www.pro-sound.com/c/hawk-woods.html


Two of the powering choices from the SD recommended power list:

D-Tap to L-mount adapter for use with the optional MX-LMount battery sled.
See http://www.hawkwoods.co.uk/Prods/Product/LR-05.

The LR-05 allows the user to power Sony NPF cameras/equipment from an external power source. The dummy NPF battery contains an 8V regulator allowing batteries of 14.4v to run 7.2-8v cameras/equipment for a much greater run-time.

Power-con (D-Tap) - 45cm - Sony Type NPF dummy battery


Hirose to L-mount adapter for use with the optional MX-LMount battery sled.
See http://www.hawkwoods.co.uk/Prods/Product/LR-06.

Hirose 4-pin (male) - Sony NPF Dummy (45cm) 8V Regulated

The LR-06 is a dummy battery which allows the user to use a higher capacity external power source for greatly extended run times. Ideal when powering cameras such as NEX-FS700, PMW-EX1 & PMW-EX3.

I tried one of the cables that he highly recommended , with the resistor , and it doesn't work. From my reading the resistor provides protection against too high of a current difference between the USB-a side and the USB-c side, but should allow for sufficient amperage to pass through for our needs and yet it doesn't work. I don't entirely understand the subtleties =. I suspect the cables Ted found dont provide the resistors and just pass the power though. This may be fine but its the same problem the google engineer found with cables before he started reviewing them.

The l-mount alternative is a good one but the stuff is cumbersome in my opinion. It would allow me to use the USB-0c port for streaming however, so I will probably try this also

Which cable didn't work?

I'm probably ordering this one:

https://www.amazon.ca/gp/product/B01A6F3WHG/ref=ox_sc_act_title_1?smid=AREE309N4XPXI&psc=1

It's an Anker cable so I figure it should have a good chance of working.

I have a question about AC wall adapters for when I'll be using the MP6 indoors for many hours.

The Sound Devices AC Adapter- MX-Charge is listed as 17W.

Would any USB-C adapter/charger with a rating above 17w probably work as well?

Such as this Anker 24W:

https://www.amazon.ca/PowerIQ-Anker-Charger-PowerPort-included/dp/B01CJ90J6O/ref=cm_cr_arp_d_product_sims?ie=UTF8

There's also a very cheap Ravpower which comes with online warnings about using it with high-draw devices. This is from an Amazon reviewer:

https://www.amazon.ca/Type-C-Charger-RAVPower-MacBook-iSmart/product-reviews/B01M0J689A/ref=dpx_acr_txt?showViewpoints=1

"As others have pointed out, the microchip inside the charger was incorrectly programmed so it does not limit itself to the rated output (36W). However, if you plug in devices that do not pull more than 36W of power, you will be fine. I use it as secondary chargers for my Macbook 12" and smartphones and the charger barely gets warm. So if you have Macbook Pro or Dell XPS, stay away from this charger - it's not rated high enough for your devices anyway and because of the flaw, it can be dangerous."

Would I be okay using it with the MP6 as an AC adapter or am I courting danger?

The google engineers eview says it is complaint and

"On the technical side, this cable conforms to the USB Type C Specification version 1.1, meaning that it correctly identifies to the Type-C device that it is a legacy USB cable using a 56k' pullup to Vbus. For charging, this means that this supports BC 1.2 charging speeds, up to a maximum current of 2.4A at 5V."

You would think thus cabe would work

If you are trying to provide 4 channels of phantom power or just have the power light stay green, No, I don't believe it would work - it needs to have a maximum of 3A at 5V to work based on what Paul posted. The device needs 15W over USB C. The only cable that can support this is a USB C to USB C cable.

Again, Sound Devices has already posted a document on what they recommend and there is a recommended battery on this document:

Here's the list with an approved USB battery
https://www.sounddevices.com/tech-notes/mixpre-3-mixpre-6-powering-options

And here's the battery
https://www.amazon.com/dp/B014ZO46LK/ref=sr_1_10?ie=UTF8&sr=1-10&tag=ianker-20&linkCode=as2&camp=217145&creative=399373&creativeASIN=B014ZO46LK&keywords=battery+charge&qid=1496527076&kwr_id=179

Buy that battery and an approved USB C to USB C cable. Here's the cheapest option that is proven safe (on Benson's list)
https://www.amazon.com/gp/product/B01GGKYZQM/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Otherwise use the 2x USB A to USB C Y cable that comes with the unit and plug both the USB A ends into a battery

There are no right angle USB C to USB C cables that are proven to be safe. None of the USB A to USB C cables (including the right angle ones) will provide enough power to keep the light green if they are built to the appropriate standard. If they seem to be working, they are not performing according to specification and may ultimately cause damage.

This is one of the few C to C cable that is at an angle but it hasn't been tested and there are no reviews. It also goes to the side and will block the XLRs or run out the front of the Mix Pre. I am going to pass until I see it has been tested.

https://www.amazon.com/gp/product/B01N41JUI4/ref=ox_sc_sfl_title_1?ie=UTF8&psc=1&smid=A21TE5CLHZDYA7

I personally would not risk a $7-900 brand new device by using an untested cable or one that is not built within spec. I also would not advise trying to save a few dollars on an untested or faulty power supply.

Thats why I am going with a USB-c solution.  My questions about USB-a to USB-c cables are because to I am interested in knowing why the cable wont work. If the mixpre requires a minimum of 15 watts that explains it.

This is from the "Sound Devices - MixPre-3 & MixPre-6 Powering Options" page:

"To fully power the MixPre-3 or MixPre-6 from a USB power source not listed above, you will need BOTH of the following:
1. USB-C power source that is compliant with the USB powering specification and is able to output 7.5W
2. USB-C cable that incorporates the correct pull-up resistors to identify itself as able to provide 7.5W

NOTE: A USB-A power source used in conjunction with a USB-A to USB-C cable cannot deliver the required 7.5W for full power operation."

I can't find where Sound Devices posted the requirement of 15W.
Title: Re: Mix-Pre 3/6 USB Batteries (what works and what doesn't)
Post by: johnw on June 04, 2017, 05:03:40 PM
My apologies as I do appear to be mistaken about the power wattage requirement. Not sure why SD would say that a USBA to USB C could not deliver 7.5W assuming 2.4A output. I have a few of these chargers made by apple that provide 12W...

https://www.apple.com/shop/product/MD836LL/A/apple-12w-usb-power-adapter

Given people's experience with the orange light on the Mix Pre when powering over a USB A cable, I would have to assume that the 7.5W is a typo and it is indeed trying to draw more current than 2.4A. Alternatively, the batteries aren't providing more than 1.2A but that seems less likely

Post by: rippleish20 on June 04, 2017, 08:21:53 PM
It looks like the "default" amperage for USB 3.1 is .9 amps. A complaint USB-c to USB-a cable is supposed to use a 56 kΩ resistor, limiting it to .9 amps. A USB-c to USB-c cable uses a 10 kΩ resistor, which allows for up to 3 amps. I would assume the cables that have been found to work by Ted either dont have resistors or have a 22 kΩ, allowing for 1.5amps, which is presumably the minimum needed for the mixpre.

Specifically, using this charging cable, the Chromebook Pixel will attempt to draw 1.5A of current over the cable, potentially damaging the USB hub or charger on the A side, which is not guaranteed to be rated at 1.5A.

Please see Section 4.11 of the Type-C specification and the following note :

1. For Rp when implemented in the USB Type-C plug on a USB Type-C to USB 3.1 Standard-A Cable
Assembly, a USB Type-C to USB 2.0 Standard-A Cable Assembly, a USB Type-C to USB 2.0 Micro-B
Receptacle Adapter Assembly or a USB Type-C captive cable connected to a USB host, a value of 56 kΩ
± 5% shall be used, in order to provide tolerance to IR drop on V BUS and GND in the cable assembly.

In other words, since you are creating a USB Type-C plug to a USB 2.0 Type-A Plug assembly, you must use a resistor of value 56kΩ as a pull-up on CC (configuration channel). According to my testing, your cable uses a 22kΩ pull-up, which is not legal when the other end of the cable or adapter is a legacy Type-A or Type-B connector or receptacle.

I bought one of these and it works with no issues. Its very thin and very simikar in size to the mixpre itself

https://www.monoprice.com/product?p_id=16240

I bought one of their USB-c to USB-c cables as well as the Amazon one and both work as expected with the battery. The Monoprice cable is thicker an stiffer. The Amazon one seems perfect for use with the Mixpre as its supple and fits tightly and give me less of a "this is going to damage the port" feeling than with the other cable, especially the one that comes with the Mixpre

My conclusion is the best route is to use a battery equipped with USB-c output and a USB-c to USB-c cable. The optional AC power supply delivers 5v @ 3Amps (15 watts), which is what the USB-c Anker battery they suggest outputs. This probably is what the unit would like to see.


I bought one of these for testing

https://www.monoprice.com/product?p_id=16240

Output 2: USB-C 5V/3A



SD says the unit need 7.5 watts 5v x 1.5 amps) - this is probably the minimum needed.

The limiting factor with using a USB-c to USB-A cable and  USB-A centric battery appears to me to be the cable. These cables must be limiting amperage to .9 - 1 amp. I was also under the impression USB batteries could output 2.1-2.4 but only some cables will actually pass this through. The dual USB-a cable gets around this by doubling the amperage. I ran tonight with both USB-a end connected to the same battery and did not get warnings and have a full green plug.

Ted found two USB-C to USB-A cables that work with his current batteries. These must pass through the full amperage.  As far as I an tell this goes against the safety precautions that should be a USB-A to USB-c cable but these cables also have downwards USB-c connectors and are very appealing fro ma cable point of view

Bingo! The problem here is PROBABLY the cables being used. I know that MP3/6 comes with a Dual USB A>USB C cable, but I still think the proper USB A>C cable will power the MP6 just fine! And if the Powercore 20,000mah battery can pump out 2.4A per port, and you're using the SD Dual USB A>C cable, then it SHOULD be giving the MP6 4.8A from BOTH USB ports, not just 2.4A total from BOTH ports ;) So I don't see why a single USB C>C cable would give a higher output than 4.8A using the Dual USB A>C cable ??? Even if your battery/charger is outputting 3A, if the cable can't handle speeds that fast, then the nicer battery will have zero effect. But what I can't understand is that if the MP6 needs 3A, why can't the included Dual USB A>C Cable provide enough juice @4.8A with both USB ports?

I JUST went through the process of giving away ALL of my old USB cables and doing LOTS of USB cable research, and bought ALL new Anker stuff recently [including their Powerline USB cables & Powerport chargers], and I couldn't be any happier! I'll def be buying an Anker 20,000mah Powercore AND Powercore+ to see if its really the battery, or the cables :) I can't recommend Anker stuff ANY more!

Post by: F.O.Bean on June 07, 2017, 11:01:15 PM

I tried one of the cables that he highly recommended , with the resistor , and it doesn't work.

Which cable didn't work?

I'm probably ordering this one:

https://www.amazon.ca/gp/product/B01A6F3WHG/ref=ox_sc_act_title_1?smid=AREE309N4XPXI&psc=1

It's an Anker cable so I figure it should have a good chance of working.

https://www.amazon.com/gp/product/B010VFFU1W/ref=oh_aui_detailpage_o03_s01?ie=UTF8&psc=1


The google engineers eview says it is complaint and

"On the technical side, this cable conforms to the USB Type C Specification version 1.1, meaning that it correctly identifies to the Type-C device that it is a legacy USB cable using a 56k' pullup to Vbus. For charging, this means that this supports BC 1.2 charging speeds, up to a maximum current of 2.4A at 5V."

You would think thus cabe would work

If you are trying to provide 4 channels of phantom power or just have the power light stay green, No, I don't believe it would work - it needs to have a maximum of 3A at 5V to work based on what Paul posted. The device needs 15W over USB C. The only cable that can support this is a USB C to USB C cable.

Again, Sound Devices has already posted a document on what they recommend and there is a recommended battery on this document:

Here's the list with an approved USB battery
https://www.sounddevices.com/tech-notes/mixpre-3-mixpre-6-powering-options

And here's the battery
https://www.amazon.com/dp/B014ZO46LK/ref=sr_1_10?ie=UTF8&sr=1-10&tag=ianker-20&linkCode=as2&camp=217145&creative=399373&creativeASIN=B014ZO46LK&keywords=battery+charge&qid=1496527076&kwr_id=179

Buy that battery and an approved USB C to USB C cable. Here's the cheapest option that is proven safe (on Benson's list)
https://www.amazon.com/gp/product/B01GGKYZQM/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Otherwise use the 2x USB A to USB C Y cable that comes with the unit and plug both the USB A ends into a battery

There are no right angle USB C to USB C cables that are proven to be safe. None of the USB A to USB C cables (including the right angle ones) will provide enough power to keep the light green if they are built to the appropriate standard. If they seem to be working, they are not performing according to specification and may ultimately cause damage.

This is one of the few C to C cable that is at an angle but it hasn't been tested and there are no reviews. It also goes to the side and will block the XLRs or run out the front of the Mix Pre. I am going to pass until I see it has been tested.

https://www.amazon.com/gp/product/B01N41JUI4/ref=ox_sc_sfl_title_1?ie=UTF8&psc=1&smid=A21TE5CLHZDYA7

I personally would not risk a $7-900 brand new device by using an untested cable or one that is not built within spec. I also would not advise trying to save a few dollars on an untested or faulty power supply.

Well said brotha! I already decided I wanted to buy Anker USB Batteries and Chargers & Cables from NOW ON, so I'm probably going to give the Powercore+ a try first! With the included USB C>C Cable and the A & C Outputs, for $65/Shipped, seems like a great deal to me and a great way to make sure your device is being properly powered from a RELIABLE company ;) No reason to risk a $900 deck with a $1.50 cable :)

Also, I just did some research on the different Anker batteries! Here's what I found out! I obviously HAVEN'T used a MixPre3/6 yet, but after reading this thread and NUMEROUS different cables and batteries for my MP6, here's my conclusions and opinions!

The Anker batteries ALL differ in their output! They make quite a few different models that output 3A@MAX, but unfortunately the Powercore 20,100 you bought, only supplies 2.4A/per port :( If you'd have gotten the Powercore 26,800 or a few of their smaller sizes that output 3A, then I'd bet the farm that you'd be FINE with a SINGLE Anker USB A>C cable from the 3A port on that battery! They make a bunch of different batteries, and only a handful of them have USB A ports that can output 3A. So that said, I will DEFINITELY be buying the Anker batteries that can output 3A@MAX, so that they can RELIABLY supply enough power to my MP6 using a single USB A>C or USB C>C cable! As always, I'll keep yinz updated on all of this once I get my MP6 in hand and try out all of the different cables that I got for it :)

I'll be buying an Anker USB battery with a 3A@MAX USB A output here soon to test it out with the MP6 and my Anker Powerline USB cables and Adapters! Damn, that's a lot of typing USB :P And I also plan on buying the 8xAA Battery tray for my MP6! I don't like how cumbersome and how much bigger the L-Mount Battery Tray is, so I'll be avoiding the L-Series batteries for right now! But I like the extra height that the 8xAA Battery Tray gives the MP6, since it's so damn small ;D

I use the Anker Powercore+ with my mp6, and works perfectly. The battery comes with a usb-c to usb-c cable, as well as a usb-c to usb-a cable (which can be used to charge the battery). A usb-a to micro usbcable is also included.

I would suggest contacting Sound Devices before buying a battery. According to Paul Isaacs and the manual, a properly designed USB A to C cable won't provide enough power for phantom on all 4 channels. If such a cable is providing enough power, it isn't designed to spec and may damage the Mix Pre or battery. I don't understand why a properly designed cable won't provide the required 7.5 W as I believe it should pass 1.5A at 5V with the proper pull down resistor selected. If someone here has the 26800 and it powers a Mix Pre 6 with including USB A to C (that is within spec), I'd love to hear about it. But unless Sound Devices says it will work, or someone else proves it works (again with a certified cable), I wouldn't buy that battery as it doesn't have a USB C 3A output.

If it helps, I will post a picture of the size of the USB A to C right angle cable I have vs the straight USB C to C. There isn't much difference.

Also, would it be worth moving this thread to the Remote power section?

Ugh. Read what I posted earlier in this thread:

1. According to Spec, a USB-A to USB-C cable is limited to providing .9 amps. Yes some cables allow for more the .9 amos but they are violating the spec. This is why they provide the y cable 2 x .9 = 1.8 amps. A USB-c to USB-c cable , however, can allow through up to 3amps according to spec. These cables use a different resistor.

2. The fact that your USB-A battery can output 2.4 amps or whatever is not important as the cable can only allow through .9 amps if it meets spec!
   
   The SD tech note on battery options says NO USB-c to USB-a single cable will work. Paul says using such a cable that happens to work is at your own risk because it violates the spec!

   Yes, a USB-c to USB-a cable with the right resistor would pass through 1.5 amps but the spec says these USB-c to USB-a cables need to use the 56 ohm resistor which limits it to .9 amps. My earlier post includes a comment from a amazon review by the google engineer who has been testing cables to see if they follow spec and is about that exact scenario - where a cable has a resistor which will allow 1.5 amps through and the engineer explains that this breaks spec

3. Any USB-c battery which outputs up to 3amps should be ok. The anker is fine but if you want something less expense the monprice is fine. The Amazon USB0c to USB-c cable has the resistors and is to spec, which limits it to 3amps anyways.

4. The powercore 20100 is not the same as the powercore 20100+ - the + has USB-c output and can output 3amps

Thank you. This is a very succinct/clear summary of what I feel is a complex and confusing problem.

If someone wanted a higher capacity battery, I believe the $99 Power Core+ 26800 would work just as well as the 20100+ as both have USB C 3A outputs.
https://www.amazon.com/dp/B01MZ61PRW/ref=psdc_7073960011_t2_B01K6TA748

Note that this is a different battery than the below $69 Power Core + 26800 which DOES NOT have a USB C output but claims to have 3A outputs (over USB A connection)

My guess would be nothing. USB-a batteries with an output of 1.5 - 2.4 amps are probably totally safe in  conjunction with a cable thats allows that to pass through. Ted has been using such a setup with no problems. The spec is designed to protect people from scenarios where one side is sending or asking for more than the other side can handle. I did the research because I wanted to know WHY the cables weren't working. My personal preference is to use cables in spec...

I am not sure, but there are a number of reports of damaged macbooks, android phones, etc from using an incorrect cable. I believe in this case, the mp6 is looking for 1.5a over a cable that should only be spec'd for 0.9A. I would imagine this could generate heat along the cable and possibly battery. I wouldn't risk it.

EDIT: ripplephish20 beat me to a response and I think he has a much better grasp on this than I do. I still wouldn't do it. The USB C straight cables don't protrude significantly more than the right angle USB C cables and they both wiggle pretty significantly on the Mix Pre. There just isn't any reason in my mind to use a USB A to USB C cable.

The MixPre is not looking for 3A. It needs 1.5A at 5V i.e. 7.5W

A USB-C to A cable that has a built-in resistor to allow the MixPre to draw full power from a USB-A power source that can't deliver 7.5W could potentially damage your USB power source or cause the MixPre to not function properly. You use these cables at your own risk. Be sure that your USB-A source can deliver 7.5W (1.5A at 5V)

thanks for the reply. All the numbers I guess had me confused, for example the SD approved battery says it's output is 2.4 (3) on Amazon so I was thinking it wanted more than 1.5.

But if I am starting to uunderstand all this more and correctly, any USB battery that outputs 1.5A should work as long as the CABLE is made correctly?

This is a battery I have, https://www.amazon.com/RAVPower-Portable-Technology-Smartphones-Black/dp/B00XC1WAQ6/ref=sr_1_1?s=wireless&ie=UTF8&qid=1496935968&sr=1-1&keywords=ravpower+10000
It states it is "smart" and outputs up to 2A on each port based on device draw. Does anyone know if this type of battery would work?
If I'm understanding correct, this battery paired with cable that can pass the 1.5A should work

Is there any real "danger" of using a cable that passes more power then it is supposed to be spec at?
I mean if your battery outs 2.4 and the mp6 is looking for 3, what's the potential issues??
I could see if the mp6 was looking for 3 and your battery was sending sayyyyy 7

The MixPre is not looking for 3A. It needs 1.5A at 5V i.e. 7.5W

A USB-C to A cable that has a built-in resistor to allow the MixPre to draw full power from a USB-A power source that can't deliver 7.5W could potentially damage your USB power source or cause the MixPre to not function properly. You use these cables at your own risk. Be sure that your USB-A source can deliver 7.5W (1.5A at 5V)

Actually if the cable is made correctly, it won't work. Any cable with a USB A end that is built to spec should only pass 0.9A and therefore would only provide 4.5W (not 7.5W)

However if you buy a cable that is not made correctly (not to spec), it might pass 1.5 A and might work, but is not supported and may cause damage.

 "this battery paired with cable that can pass the 1.5A should work"

yes, the battery info says

Output: USB A1: 5V/2.4A max, USB A2: 5V/2.1A max



"any USB battery that outputs 1.5A should work as long as the CABLE is made correctly"

yes and no depending on how you define "correctly". A cable that passes at least 1.5 amps should work with any USB-a based battery that outputs at least 1.5 amps per port. This is not "correct" in the sense that such a cable goes against spec. Paul points out a scenario where using such a cable is a bad idea. If you plug such a cable into a port that can't output 1.5 amps you have a device wanting to draw 1.5 amps but cant - this is exactly why non spec cables have damaged equipment in some cases...


I realize how confusing this all sounds. I think I understand the issues at this point but feel free to correct me if someone finds out differently

Thanks guys, I got it now, I think ;)

So using USB-A, for it to work...
The cable must be made NOT to spec and could cause damage
The dual USB-A cable supplied from SD must be used

Using USB-C...
Those cables have a higher spec rating and so should work as long as the battery can output 1.5A

Thanks for the detailed info guys! If Paul said that can cause an issue, then I'm ordering the PowerCore 20,100mah that you and others have already bought, and used correctly! I'm not trying to break/ruin the ONE deck that's going to last me the next 10+ years hopefully, within the first 2 weeks of getting it, just because I wanted to try to use a USB A port :P ;) Thanks again for all of the info fellas! Before the MP6 came out, my knowledge of USB Batteries & Cables was elementary at best, and now that I've thrown away ALL of my old shit and bought new Anker stuff, I couldn't be ANY happier ;)

And would it REALLY be THAT HARD for SD to put on their site, that a USB C Port/Output MUST BE USED, so that the MP3/6 aren't damaged? I think that if it's possible to damage the MP3/6 just by using the wrong USB Batteries & Cables, that SOUND DEVICES should have MENTIONED THAT before a shitload of people buy USB A Batteries, and then have to return them like I have to do now, or even worse, damage their deck :P It only takes a SECOND to put that info SOMEWHERE on their website under the MixPre-3/6 web pages, so that it doesn't KEEP happening to people!

That said, I really appreciate Paul Isaacs@SD coming here onto TS.com and answering our specific questions. Without Paul coming here, we wouldn't know the specifics about the current that we now do ;D 8) So Thanks again Paul, you RAWK!!! :coolguy:

Totally agree with that Bean!  I think that it is/was negligent of SD to not have stressed the importance of using a specific combination of "accepted" components to power the new MixPre series without risking damage to the equipment.

OK, just added this to my Cart and I'm buying them as soon as I get the rest of my PP $$ together soon 8) I am just getting the extra Anker Powerline USB C>C cable because it's badass, and should be a fast enough cable@60w to last me a lifetime for the MP6 or any other C>C devices I have[my Google Pixel phone] so that I can charge and power as fast as possible! I wonder if this cable WILL or WON'T work with the MP6 though? It goes UP TO 60w, but should be just fine supplying the 7.5-15w that the MP3/6 needs, right? And you can't beat Anker giving you [2] cables with the battery below that SD recommends! A USB A>C to charge the battery[from my Anker PowerPort 2 & 6], as well as a C>C cable to power your device[MP6 in our case]. Anker, I love you lol ;D Anyway.....

I also like the power button for the above battery being on the top of it, vs the side power button of most of the PowerCore Batteries, since it seems the above battery won't accidentally turn ON/OFF as easily as the side button PowerCore batts, where it seems like that would be easier to occur?!

Numerous people have posted about this in the regular Mix-Pre thread. There are a lot of variations. I believe all the postings were about using a 2 phantom powered mics. I personally get about 2.5 hours, but less if the rechargeable batteries I'm using at any one time have already been recharged numerous times over the years. Some folks get less, a few get more. Of course if you are using dynamic mics you should get a lot more time out of batteries.

Got my MixPre-6 on Thursday. Really nice machine.

I've had to spend a lot of time figuring out the system so as to record in my usual setup. So this morning I finally did a battery test.

Running the MP6 at 24/192, recording only on Channels 1 & 2 (did NOT record the MIX LR tracks), phantom power on both channels, Bluetooth OFF, LCD at 1, LED at 2, using POWEREX Imedion 2400 mAH NiMH batteries, I got 2h16m runtime.

Thanks for the summary, much appreciated. Had thought of turning my two warm mod 661s into a mixpre 3 but that battery life is cutting it too close for me, that's about what my 661s do mic in. Still, what a cool little box.

Remember there are a lot of powering options including the 8 AA battery sled, the Sony battery option (which apparently gets very long life), and some other powering options. Still the MixPre-3 would not be for you ... but I wouldn't let batteries get in the way. There are several nice powering options. I only need about 2 hours max at a time, so I'm happy as is. Otherwise I'd go with some of the higher end options.

This is just a baseline test, but I recorded a SBD feed (with lowered LED and LCDs) and got well over 5 hours with the 8 battery sled. And the plug was still green when I turned the deck off.

As far as Ankers go, I'd assume this bundle would work, as well? Includes charger and USB-C to USB-C cable...

Yes I believe that should work. Pretty good deal as the cables and charger are worth $35-40.

Confirming. Definitely works!

Very similar dimensions to the 20100 mAh model on the SD approved list, while providing significantly more capacity.

Also, supports USB-C Power Delivery (PD) spec, which (rapid) charges my Google Pixel XL, among other things.

Having a small L mount battery (like the Sound Devices XL-B2) would allow you to hot swap batteries connected by Hirose without interruption.

This is a much more expensive option; your looking at $200 for the sled, dummy, and hirose > external adapter cable. I agree this is a better option because then you can use a small L series battery as backup (https://www.amazon.com/Sony-NP-F570-InfoLithium-Battery-DCRVX2100/dp/B0002Y5WVQ), hot swap externals, and of course the dummy is on the approved list.

I agree this is a better option because then you can use a small L series battery as backup (https://www.amazon.com/Sony-NP-F570-InfoLithium-Battery-DCRVX2100/dp/B0002Y5WVQ), hot swap externals, and of course the dummy is on the approved list. Did the $99 for the dummy battery include shipping?

See http://www.hawkwoods.co.uk/Prods/Product/LR-06.


^
I already have the L-mount sled.  I don't know if the LR-06 $99 quote included shipping.


£139. They're mods so they're having to purchase the existing 4bays I think.
http://www.pinknoise-systems.co.uk/ have made some 4 pin regulated Hirose power adapter prototypes that they say should be up for sale in a few weeks.

The similar option mentioned by b_curl runs $177 US dollars if the price is £139.

The Hawk-Woods adapter regulates the incoming voltage to 8V! I like the option better than the USB-C external.

What does the Hirose connect to in this scenario - a sled with multiple LMount batteries? Could you use a custom cable to 12v battery?

See this:  http://www.hawkwoods.co.uk/Prods/Product/LR-06

The Hirose from the LR-06 dummy cell will connect to a Naztech PB15000 battery, Naztech PB15000 battery cable with a female Hirose connector.

Cable like this. I'd ask tgakidis to make one instead of buying off Amazon though.

Actually, looking at the Hawkwinds product, it may have a male hirose plug on it. You might need a female cable made since I think most of the cables Ted makes are male plugs as well.

All of these hirose options regulate to 8.4v so I'm under the impression that you can throw 9v-12v at it and be fine.  12v probably just generates a little more heat.

I am more likely to go for the other other company's product, as, with it, you dont need the l battery sled, and it has female hirose... I am set for the moment between battery sleds and USB-c battery so I'll let othere people figure out the details with these products

Thanks for the info on that! I'll be using the 8xAA or 4xAA Tray's with the USB C power supplies! In have NEVER liked those L-Series Lithium batteries, and I even avoided using them when I had my old SD722! If I do use the L-Series Mount, I'll DEFINITELY be using it with a Dummy Cell like Dactylus posted! That's how I used to power my old SD722 and was my preferred method of powering it!

Also folks, with the Dummy Cell wired correctly, you can even run 7.2v NIMH RC Packs! Obviously not as lightweight as Lithium, but IMO, NIMH is a more reliable and trusted technology! At least it USED to be! That's how I used to run my 722 and I have ALWAYS preferred NIMH technology to Lithium! I realize that USB batteries are just Lithium 18650 batteries, but I feel much safer running those because of the added technology that companies like Anker build into their chargers & USB Batteries! Anker has something called "Multi Protect" which has 10 different kinds of technology & regulators that make sure your devices being powered are as safe as possible!

Also, I got my MP6 yesterday, and ran it through some battery tests! I was using 2 year old Energizer 2,300mah NIMH AA's in my SD 4xAA Battery Tray! I ONLY GOT about 2 HOURS, whether the Bluetooth was on/off, as well as the LR Mix being on/off! I was running 4 channels of my 60v PFA's @24/96 directly into my MP6, which is what I plan to run 99% of the time, so that I can leave my heavy VMS02IB at home more often ;D I'm trying out a 10,000mah HoneyComb brand USB A Battery, with the included SD Dual USB A>C Cable, right now and I'll let yinz know about how long the 10,000mah battery runs!

I already have the Anker PowerCore+ 20,100mah USB C Battery & Anker 60w Powerline C>C Cable with Power Delivery, which should be here anyday! And I am DEF getting a few of those Monoprice USB C batteries linked above! I have some Monoprice USB items and they're a decent enough company IMO! Nowhere near as nice and reliable as an Ankerm IMO, but will still get the job done! Besides, Anker is the best USB company of anyone right now! ;) 8)

Yeah, great price for you guys down there. More than twice that up here in the Great Frozen North (but a warm summer night tonight!). I managed to score one from an online Canadian dealer at 30% off so it was still worth it. They are light too, so you could carry a couple in your bag.

I'm using this one:

It's actually too long because it's doing double duty as the connecting cable from the MP6 to an A/C wall charger. But I've ordered a shorter cable. This one:

Fosmon USB-C to USB-C Sync Charge Data Cable

I think both cables are well reviewed by the USB-C online guru Benson Leung.

Hello, nice to meet you.  :)
I recently bought a MixPre-6 and found this forum.
And I want to ask for advice.

I bought a "RAVPower 26800 PD USB-C Charger 26800mAh" with MixPre-6, but RAVPower can not supply power to USB-C devices with a USB-C connection.

[Specification]
-- Micro USB Input: DC 5V/2A
-- Type-C Input: DC 5V/3A,9V/2A,15V/2A,20V/1.5A
-- Type-C Output: DC 5V/3A,9V/2A,15V/2A,20V/1.5A
-- iSmart USB Output: DC 5V/3.4A Total(Each 2.4A Max)
-- https://www.amazon.com/gp/product/B01LRQDAEI

Anyway, I plugged the "USB-A to Micro USB(And plug the USB-C adapter into the Micro USB connector)" cable into the RAVPower's USB-A port and plugged the other end into the USB-C port of the MixPre-6.
It's not full power, but it works. (Power Status Icon = Orange USB)

I have connected two stereo microphones(battery powered) and RodeLink(mono), and stereo mix and ISO track recording is fine. (stereo mix LR tracks plus 5 isolated tracks).

Is it ok to use this?
I am afraid that MixPre-6 will fail.

The "USB-to-Micro USB" cable and the "Micro USB to USB-C adapter" used the one provided with RAVPower.
Perhaps this is the same product.

I have the same battery and use the USB C to USB C with no issues at all. It will supply the correct power much like the Anker battery.
Your battery powered mics should be fine, just make sure phantom power (p48) is off.
Your English is fine, good luck!

Thank you for your answers and advice.  :D
After reading this article, I was worried and posted an article.  :o


The MixPre is not looking for 3A. It needs 1.5A at 5V i.e. 7.5W

A USB-C to A cable that has a built-in resistor to allow the MixPre to draw full power from a USB-A power source that can't deliver 7.5W could potentially damage your USB power source or cause the MixPre to not function properly. You use these cables at your own risk. Be sure that your USB-A source can deliver 7.5W (1.5A at 5V)

I will use this connection(Power Status Icon = Orange USB) for a while until I get a replacement.

The comments above are not related to USB C to USB C. They are related to the many USB A to USB C cables being sold that do not have the proper resistor. There are within these pages links to USB A to USB C cables that are safe. But that is geared toward the older batteries that do not have any USB C capabilities. The Rav Power battery you have purchased is designed to go USB C to USB C, so if you have the USB C to USB C cable that came with it, you will be fine. Running under the orange color from what I have read (I have no personal experience) means that you can only run 2 channels as it is in safety mode.

Also remember you can email Sound Devices directly. I have done so and I received a response within a day.

Yes, I know that the comment is not related to USB-C to USB-C.
I am concerned because I am currently using USB-C(MixPre-6) to USB-A(RAVPower 26800 PD) connection.
(In fact, I used the "USB-A to Micro USB(And plug the USB-C adapter into the Micro USB connector)" cable.)
(And I do not even know if there is a proper resistor on this cable.)
This is because the USB-C port of RAVPower is not working.

I saw this today. I'm surprised SD haven't come up with a sled that has the Hirose and regulator all built in. Seems a total no brainer. Could even make it with the 8xAA sled and leave space for 4 x AA.....
In fact, anyone can find suitable regulator on ebay, Hirose on ebay, plus some solder skills. What's to lose?

So what is the smallest external solution? My hopes were to run this for at least 5 - 6 hours using the 4 battery sled and Lithium AA's. With my mics I'm only getting 3 1/2 hours. I guess my options are the 8 battery sled or a small external. So far all the externals listed are larger than the deck. I have the 3. Thanks.

Has anyone found a braided / techflex USB-C to USB-C cable that meets the specs for powering a MixPre-6? I ask because I feel a braided cable will wear better over time.

This braided Anker cable claims to support USB Power Delivery but indicates a USB v2.0: https://www.amazon.com/dp/B071XYBPMN

This non-braided version (also supporting PD) indicates v3.1: https://www.amazon.com/gp/product/B01EMIIFCU

I gather the USB version isn't relevant for powering a MixPre. But should not any cable supporting Power Delivery do the job here?

Anyone have experience and/or thoughts to share on these options?

Did a partial runtime test on the Anker Powercore+ 26800 with MixPre 6.  I shut it down after 12 hours and still had 5 of the 10 LED lights lit on the battery.  Used the supplied USB-C cable and ran phantom power to both a pair of Peluso cemc6 and Line Audio CM3 and recorded the mix, for 6 tracks total.

The Omnicharge power bank was mentioned earlier in this thread (by johnw, reply #44) but a heads-up that they just announced a version with USB-C.  There's a few things I'm not crazy about with the original Omnicharge, but the company obviously takes care in their development so I imagine their USB-C will be on-spec and well designed. > https://www.indiegogo.com/projects/omnicharge-most-powerful-dual-usb-c-power-bank-smartphone-powerbank#/ (https://www.indiegogo.com/projects/omnicharge-most-powerful-dual-usb-c-power-bank-smartphone-powerbank#/)

PROS:
1. Well-built and outputs clean, accurate power.
2. Price during initial backer's run is $150; street price will be ~$250 after the initial backer's run is over.

CONS:
1. Addition of the two USB-C ports sacrifices the full-size AC output and barrel DC input/output of the original Omnicharge configuration. 
2. Won't be shipping until December 2017 and could be later (mine was ready and shipped nearly 2 months after the projected date).
3. (Personal con) A few less than optimal design and implementation choices that I noted in my observations here. > http://taperssection.com/index.php?topic=178998.msg2219228#msg2219228 (http://taperssection.com/index.php?topic=178998.msg2219228#msg2219228)

I bought one of these Moshi IonSlim for < $20 on eBay (brand new) and with the 4AA sled, I get right around 8 hours. I would guess 5 hours with just the ext. battery. For low-pro, I couldn't imagine a lighter, slimmer battery. Samsung also makes a usb-c battery with a similar rating, which has similar run times. The cable I posted earlier works with all 4 of the usb-c batteries I have tried (Anker, Jackery, Moshi and Samsung).

The picture shows USB micro, not USB "C". This model battery comes in a USB "C" model as well as this one. I have both (although not exactly the same model on close inspection) and the USB "C" model powers the mix pre with no issues.

Yes, that was my mistake. The one he has does have USB-c out.


10% of the people on Amazon rate the battery as a 1 out of 5, however, and there is this question:

By JTompkins on April 30, 2017
Actually, I just tried something out. I saw that my phone was charging the battery pack so i just rotated the usb connector 180 on my phone and plugged in and then it started to charge the phone. That's weird! Who the heck would want to charge a 20000mah battery using a phone??? Dumb! But it works now, at least.
By JTompkins on April 30, 2017

I admit the question and some of the answers are confusing, but I wonder if there are quality issues such that some people experience issues trying to use the USB-c for output

I run my mixpre either 4 channel (2 x kcy> ipa> mic in on mp6) or 6 channel (2 x Schoeps actives> PFA mic in to 1-4, and naiant littlebox line in to 5/6) with the lights on full. I record from the moment I'm set up until the deck gets turned off when the lights go on after the encore. I've never used more than 25% capacity of the battery, and no longer even run the AA tray at all.

$65 for at least 15 hours of full operation? It's a no brainer to me. Right angle USB - C is plenty secure on both ends.

I will let Noah answer for himself but I think that he meant that his machine never uses any of the AA capacity and not that he leaves the tray physically disconnected.  Personally, I would not do that just in case something fails.  I know that silly AA tray saved my ass for a recent Kimock show I recorded.  I turned my machine off during set break and when I powered it back up I guess my 26800 had gone to sleep.  I was lucky I had fresh AA's in, as well as haven't the luck to glance at the battery indicator on the MP6 and see it half gone.  I disconnected the USB cable and reconnected it to wake it up since I did not know that little wheel was a button.

Just got one today and love the size!  Got the right angle c > c posted a while back and they show green on the mp6.  I have an Anker PowerCore+ 26800 which is great but it's big, heavy and overkill except for once or twice a year.

Has anyone run 4 channel with these?  Not way for me to really test that at home.  I don't have 2 sets of mics so any 4 channel will be mics on 1&2 and sbd on 3&4.

I don't think the number of channels really has impact on run time. The recorder, in my experience, uses the same amount of power whether in standby or being utilized to it's full capacity (recording on every available channel plus the mix). Hoping others can chine in with their thoughts/experiences.

Good to know. Is this the one SD recommended?

Did you have the AA sled running and if so did you end up running the AA's all they way down? More details would be appreciated.

I always have a boat load of AA's as a backup, but they won't cut it for really long sets.

Yes, it is the one that SD recommend. I was running the AA batteries but had the recording ready (powered on) about 30 minutes before the band came on. I got a little less than 45 minutes of the main set, which tells me the Anker never turned on, even after I pushed the button. My cable works fine with other usb-c batteries and the recorder has no issues running off other external batteries...the Anker just seems to be bricked.

I was holding off posting until I got everything sorted out but I also had an Anker battery failure and unfortunately it damaged my Mixpre3.  The battery was a new Anker Powercore 20100mah (not the plus model) connected via the dual usba > usbc cable.  What's strange is that I'd already used the battery three or four times prior to this...but after the failure I did realize that the battery had been  a bit funny...one time I used the battery to record with and then after the show when I tried to use the battery to play the recording back it was dead...even though I'd just recorded an entire show with it with no indications that the battery was even low.  Anyway on the day of the failure, I was in my car the day after I'd taped and was attempting to play the recording back through the aux jack on the cars stereo system.  Powered from this battery, the mixpre started up fine but a short time later the battery started smoking. Of course I quickly unplugged everything.  The battery was obviously shot after that but I didn't have a means to check the mixpre3 until I got home.  Sure enough when I got home I discovered that it was damaged. 

The battery short took out the usbc port and the green-yellow-red lights around the fader knobs.  Otherwise the unit still works fine from the rear power terminals.  This happened last week so I haven't yet contacted either Anker or Sound Devices.

I was holding off posting until I got everything sorted out but I also had an Anker battery failure and unfortunately it damaged my Mixpre3.  The battery was a new Anker Powercore 20100mah (not the plus model) connected via the dual usba > usbc cable.  What's strange is that I'd already used the battery three or four times prior to this...but after the failure I did realize that the battery had been  a bit funny...one time I used the battery to record with and then after the show when I tried to use the battery to play the recording back it was dead...even though I'd just recorded an entire show with it with no indications that the battery was even low.  Anyway on the day of the failure, I was in my car the day after I'd taped and was attempting to play the recording back through the aux jack on the cars stereo system.  Powered from this battery, the mixpre started up fine but a short time later the battery started smoking. Of course I quickly unplugged everything.  The battery was obviously shot after that but I didn't have a means to check the mixpre3 until I got home.  Sure enough when I got home I discovered that it was damaged.

Ouch sorry to hear that.
Question, did you have both usb-a connections coming out of the one battery?
If so, I think the may have been the issue as it was drawing too much from the battery. The dual usb-a to usb-c cable is designed for 2 separate batteries.

The first few pages of this thread discuss where people use the dual usba cable from a single battery and this Anker Powercore was the subject of the discussion.  In fact the focus of the discussion was whether or not the usba Powercore could provide sufficient amperage to power the mixpre.  Also it was specifically stated that both usba connectors needed to be connected to the same battery.  I'm curious where you got info that they needed to be two separate batteries.

I got a couple of there HyperGear batteries for a song and have been using them with great success. Around 7 hours on a single charge and the red/black version can be had for $23 on Amazon.

https://www.amazon.com/dp/B01KYUDAN4?ref_=pfb_29fjld6id8h4dnhiae7j64kjk55k&tag=hydfbook0e-20&ascsubtag=pfb-P01-V01-O5-T1-HI-4DCJUB&th=1

Great battery. Got about 7 1/2 hours. 2 channel. Lights and LED’s down to 1. Nice small size. Using it with a 1 foot cable. Very happy. :yahoo:

Just got one today and love the size!  Got the right angle c > c posted a while back and they show green on the mp6.  I have an Anker PowerCore+ 26800 which is great but it's big, heavy and overkill except for once or twice a year.

Has anyone run 4 channel with these?  Not way for me to really test that at home.  I don't have 2 sets of mics so any 4 channel will be mics on 1&2 and sbd on 3&4.


Ran some test with this yesterday recording the stereo in my office.  2 channel phantom, bluetooth off, lights on 3.  I got 8 hrs and 50 minutes!

I did have an issue though.  I have the 4 sled AA in as backup.  When the usb battery died it did not automatically switch to the AA's.  I did not see it happen but when I came back in to check the mp6 had an error on the screen that said "stream access error".  Behind that there was another error about usb but I couldn't see what it said.  I should have taken a picture.  I charged the usb battery overnight and this morning if I pull the cable out it switches to AA just like it should.  So not sure what happened or why.  Card is a 32gb SD branded card and was far from full.


edit:  testing again to see if it does it again.  should know in about 7 hours........

Tested again and this time I was sitting here when it happened.  Seems when the battery starts to get really low (1 bar) but not dead the power requirement is not enough to power the mixpre.  The two errors are as follows:

USB Power Source is not compliant
Use battery power instead?

OK   Quit

before I could hit ok I got this:

SD Warning
Stream access Error
       OK

When I hit ok it goes back to the usb error, hitting ok does not switch to battery as the stream error comes up again.  Then it shut off.

This happened at 8 hr's and 46 minutes and the bar on the battery at one which indicates less than 25% power remaining.  So again it seems that when the battery was super low it couldn't provide enough wattage.  That makes sense but not sure why that kicks up the "Stream access error".

Wave file wrote correctly till it cut off at the end.  The very end it "flat lines" as the battery power drained.  Battery light was green the entire time.

If this isn't going to cause problems I'm fine using it and just remembering to never push it past 8 hr's which I never need anyway.


I have not tested my Anker PowerCore+ 26800 to see if the same thing happens when it gets too low.  I plan to tomorrow.

did your's die gracefully and switch to aa?  or errors like mine?  As you may have seen in the other thread I had my mixpre lock up while testing the ankar last night.  finished the test  today and it didn't lock up and it died gracefully switching to aa.  no idea why the hypergear didn't.  I only need 8+ hours once or twice a year so if it's safe to run for 3-4 hours at most I'm ok with that.  just scares me with all the issues I'm having.

Seems the issue may have been the usb C to C cable I was using.  I was getting a green light and it worked with the Anker (gracefully switched to aa) but I got those same errors twice with it and the hypergear.  Even though it worked once with the Anker I wonder if it was the cause of the lockup I posted about in the main thread.

This is the c to c that many folks are using that may be the root of my errors.

No!  using the right angle c to c linked above gave me the errors when it should have switched to AA!  this is with the hypergear battery.  using a usb c to A with the hypergear and it switched to AA as it should with no errors.  tested twice now.

I have not tested with the actual anker cable cause I have to use right angle cable in my bag.

This all goes against what others are saying about using usb c to A.  This thread led me to seek out a c to c since that is what is recommended.  my experience is the opposite.

See my other issues with the Anker!  I was testing to see if it did the same thing (errors) when the mixpre locked up the other night!  I finished testing yesterday and no lockups and it switched to AA as it should.  Still makes me leery to use that cable.

I have an anker unit, but it’s heavy, bulky, and awkward with the usb cable so I might like to switch to L batteries.  I considered two of the 570 batteries but looked at mah ratings - the 570s are only 2300mah each, so two would give me 4600mah.  From what I read, alkaline batteries can give 2500mah each, or 10000mah total.  That just doesn’t seem right?  How long will the mixpre6 run four mics with phantom power on 4 alkalines vs two 570 L batteries?  Thanks.

I've now tested multiple times with both the hypergear and the anker and it does seem it was the c to c cable causing my issues.  with a usb a to c they both switch gracefully to AA when they die.

As far as the Anker products go with regard to powering the MixPre 3 or 6, there are several options available. I've read through all 12 pages of this thread, but I was hoping someone could clarify which ones work best with the MixPre series.

First you've got the two non-plus models, the regular 20100, $45.99, here:

https://www.amazon.com/Portable-Charger-Anker-PowerCore-20100mAh/dp/B00X5RV14Y/

and the regular 26800, $61.99, here:

https://www.amazon.com/Anker-PowerCore-Portable-Double-Speed-Recharging/dp/B01JIWQPMW/

My understanding is to stay away from these because they do not use USB-C to USB-C, correct?



Then you've got the plus models, starting with the 20100+, $65.99, here:

https://www.amazon.com/Anker-PowerCore-Ultra-High-Capacity-Portable/dp/B014ZO46LK/

I believe this link above (the $65.99 one) is the only one officially endorsed by Sound Devices?



Then you've got, confusingly, 3 variants of the 26800+, starting with this one, $69.99, here:

https://www.amazon.com/Anker-PowerCore-Portable-Ultra-High-Capacity-Recharges/dp/B01N3TVRP2/

and this one, $86.99, here:

https://www.amazon.com/Anker-PowerCore-Portable-Capacity-PowerPort/dp/B01K6TA748/

and finally a "Power Delivery" or PD version, $119.99, here:

https://www.amazon.com/Anker-PowerCore-Delivery-Charger-Portable/dp/B01MZ61PRW/

I gather from this thread that the two models people are using with their MixPres are the 20100+ ($65.99) and the 26800+ PD ($119.99)? I was mainly wondering if the other two (cheaper) variants of the 26800+ should be avoided for some reason? Those variants refer to some unspecified "included cable" but they don't specify that it's a USB-C to USB-C cable the way the $119.99 variant does.

Also, I was wondering, between the 20100+ and the 26800+ PD, if there's any way to tell about how much more runtime one might get by spending the extra $54 on the 26800+ (mainly to determine if that extra runtime is going be way beyond my needs and thus, a waste of $). Sound Devices has a handy chart comparing runtimes with various types of AAs, but they don't say anything about USB batteries (and in fact no variants of the 26800+ are even endorsed by them anyway). Any guidance would be appreciated!

I have never had a lick of problems outside of user error.

When using an Anker external battery connected to USB-C I found that [maybe only on an older fw] if you shut down during set break to make sure the recorder "sees your battery" when you turn the deck back on.  Sometimes those Ankers go to sleep and you have to push the wheel button to wake them up.  It is an old habit from days of short battery life.  My fix was to turn everything on and just let it run all night.

Has anyone found a small battery option for semi-stealth operation?

The "official" battery is a little larger than I'd like and also for mine the USB-C connection isn't the greatest for pocket use.

Ideally I'm looking for something in the 5000-1000mAh range. USB-C connection with enough power for 2 phantom power mics.

The moshi is what you want for stealth.

I bought one of these Moshi IonSlim for < $20 on eBay (brand new) and with the 4AA sled, I get right around 8 hours. I would guess 5 hours with just the ext. battery. For low-pro, I couldn't imagine a lighter, slimmer battery. Samsung also makes a usb-c battery with a similar rating, which has similar run times. The cable I posted earlier works with all 4 of the usb-c batteries I have tried (Anker, Jackery, Moshi and Samsung).

Any guidance would be appreciated!

I recognize it's likely confusing if you read though the thread but you basic question about what battery you could use comes down to one concern - the choice of cable. 

"In the USB 1.0 and 2.0 specs, a standard downstream port is capable of delivering up to 500mA (0.5A); with USB 3.0, it moves up to 0.9A. The charging downstream and dedicated charging ports provide up to  1.5A. USB 3.1 bumps throughput to  ... It also supports power draw of 1.5A and 3A over the 5V bus."

USB has traditionally only supported up to .9 amps.  The newer standards. with USB-c connectors, offer up to 3A. So what happens when someone builds a USB-A to USB-C cable? The average user could easily connect a device that only expects .9 amps to one that is delivering 3A or the reverse. So the USB cable standards dictates resistors in the cable which limit a USB-A to USB-C cable to .9 amps. This is not enough to power a Mixpre-X (which requires 1.5A) and and its why they give you a USB-C to dual USB-A cable (to get around this issue).

So you can go two ways depending on what your comfort level is. Some of the cables sold on amazon ignore the standards and allow more than .9 amps over a USB-A to USB-C cable - they dont have the resistors. A battery with USB-A output that outputs 1.5+ amps on that port will work with such a cable. If you read through the thread you will find comments about specific cables which ignore the standard and work. SD cant officially recognize this as an alternative as someone could damage their equipment so their power FAQ just says it wont work. Some people have also tried the USB-C to dual USB-A cable, plugging in both USB-A connectors to the same battery using two USB-A ports but this sounds like it can potentially damage your equipment and I wouldn't recommend it.

The second option is to stick with cables that follow the standards. This means that you need to use a USB-C to USB-C cable and a battery that has a USB-C output port offering 1.5A+ (even here some USB-C to USB-C cables, like the one that comes with the Ancor USB-C batteries, have been reported as troublesome, so you may want to avoid them although its not clear what the specific issue is)

Which of the above routes you go dictates which of the batteries would work for you. You may also want to look at the monoprice USB-C batteries as they are inexpensive.

The moshi is what you want for stealth.

I bought one of these Moshi IonSlim for < $20 on eBay (brand new) and with the 4AA sled, I get right around 8 hours. I would guess 5 hours with just the ext. battery. For low-pro, I couldn't imagine a lighter, slimmer battery. Samsung also makes a usb-c battery with a similar rating, which has similar run times. The cable I posted earlier works with all 4 of the usb-c batteries I have tried (Anker, Jackery, Moshi and Samsung).

Moshi: https://www.amazon.com/Moshi-IonSlim-portable-charger-power/dp/B072JVPVC5

fwiw, you posted that Moshi Amazon link nearly 10 months ago, and it's not available through Amazon anymore. it doesn't appear to be widely available on eBay either, though there are a couple listings there.

i tested how long my new Anker 26800+ PD would run the Mixpre-6. set it up with LED and LCD both set at 5, fully charged the battery, turned on the MixPre and just let it sit. no recording, no phantom, nothing. the MixPre was on for just around 20 hours before it shut off (20 hours 3 mins to be exact). presumably phantom powering 4 mics and recording multiple channels would result in reduced runtime, might do another test with a bunch of stuff going on to see how much it reduces it by. regardless, the Anker 26800 clearly provides way more runtime for the MixPre than any taper is reasonably going to need in one go, even if you're doing an all-day fest.

Given people's experience with the orange light on the Mix Pre when powering over a USB A cable, I would have to assume that the 7.5W is a typo and it is indeed trying to draw more current than 2.4A. Alternatively, the batteries aren't providing more than 1.2A but that seems less likely
I tried an iPad charger. It can certainly deliver a lot of current, but if you connect a standard USB 2 device it will deliver the standard USB 2 current, no more. Otherwise it might cause problems with some devices.

iPads have some extra circuitry to "milk" those adapters. That same circuitry also allows them to demand extra current from Mac USB 2.0 ports.

I can verify that this GP 10400mAh pack with USB-C for input and output works great with the mixpre-3.
https://www.reichelt.com/de/en/powerbank-li-ion-10400-mah-usb-c-gp-1c10aa-p217428.html
Notice that the USB-C model is named: 1C10AA <- Get this one

But the supplied USB-C cable is a tiny 15cm long (10 cm effective length) so it might be extremly efficient or totally worthless depending on your setup.
I'm running my from a spare 50cm Thunderbolt 3 cable which is a waste but it works great. :)


There's another model on the market which looks the same but without the USB-C which have a single A in the name 1C10A <-Don't buy that one.

You have to use both of the USB A into a battery to get full power on the Mixpre-6.  Only using one will not power the deck properly and you won't get a green battery light.  Make sense??

Post by: rippleish20 on July 24, 2018, 12:09:40 PM
SD must get a hundred emails a day about this topic as it sure creates a lot of confusion...


The USB 2 standard allowed for USB ports to output a maximum of .9 amps. For a long time, this was the maximum USB devices would expect or deliver. Some vendors - ie Apple - created  custom scenarios (like USB-A to lightning connector) that provided more than .9 amps and there were specialized variations  like USB Power Delivery for charges, but .9 amps was the standard. With the USB 3.x standards, the standard was raised up to 3Amps. The problem is that you don't want users to plug in old devices to newer batteries or power supplies and have them blow up/cause a fire, etc. So standards were developed for cables to prevent this. By the specifications, a USB-a (USB 2) to USB-C (USB 3) cable is supposed to have pull up resistors which limit the amperage to - you guessed it - .9 amps. The Mixpre-3/6 wants 1.5 amps (5 volts x 1.5 amps = 7.5 watts). This is why SD's power FAQ says:

NOTE: A USB-A power source used in conjunction with a USB-A to USB-C cable cannot deliver the required 7.5W for full power operation.

This is also why they include the y cable. A majority of people have computers with USB-A ports. People buying Mixpre's are going to want to connect them to computers as audio interfaces. Their solution - provide a y cable with two USB-A ends ( 2 x .9 amps = 1.8 amps).
 
A USB-A power source used in conjunction with a USB-A to USB-C cable cannot deliver the required 7.5W for full power operation. Some vendors on ebay and amazon, however, sell USB-A to USB-C cables that don't have the resistors in them. In this thread, some people have identified such cables. If your USB battery supports 1.5+ amps and you use one of these cables, you can get the full 7.5 watts. SD does not officially recognizer this option as it bypasses the standard (the fact that these vendors do this bothered a Google Engineer and he actually went through Amazon vendors at one point and certified whether they were following the standards). There is nothing wrong with using a non standard cable if you know what you are doing. Several people here do because they can use the USB-A batteries they had. Think about this from a vendors point of view, however, and you will realize it's not a good idea.  Some people also use the dual dual USB-A cable and simply plug both USB-A ends into their battery. Based on comments I've seen this is not a good idea at all.

Fully powered versus under=powered Mixpre. The Mixpre does have a low power mode and it can be run with less than 7.5 watts with limitations. The FAQ U linked below explains the limitations. Your battery icon will show a orange meter not a green meter.
 
ps. Can we get a picture of a talentcell running a Mixpre via the dual USB-a cable , with only one USB-A end connected, showing s full green battery indicator? That makes no sense.

Maybe I was mistaken about getting a green light with that battery. I'll double check.

From their site, though, it seems like operating in Low Power Mode is fine for my use, which is generally recording 4-channels with 2 phantom powered mics and a board feed. I don't use HDMI or USB A ports at all when recording. I assume there's no harm done to the unit by running in Low Power Mode?

Quote
To fully power the MixPre-3 or MixPre-6 from a USB power source not listed above, you will need BOTH of the following:

    USB-C power source that is compliant with the USB powering specification and is able to output 7.5W
    USB-C cable that incorporates the correct pull-up resistors to identify itself as able to provide 7.5W

If either of these conditions are not met, the MixPre recorder will operate in low power mode: maximum 2x 48v phantom channels, no HDMI, no USB-A. You can still use all of the MixPre’s channels, but only a maximum of 2 can be phantom powered.

I recently picked up an Anker PowerCore 10000 PD (https://www.anker.com/products/variant/powercore-10000-pd/A1235011) for my MixPre-6. It provides full power to the recorder (green light) and is considerably lighter and more compact than the PowerCore+ 20100 Sound Devices recommends (6.7 ounces, 4.49 x 2.05 x 0.98 in versus 1 lb, 7.24 x 2.44 x 0.94 in, according to Amazon).

I got it the day before Mule in Brussels and didn't have an opportunity to charge it before the show. When I powered up, two of four lights came on, but one of those went out on pretty short order. About midway through the second set, the last light started blinking. During the last track before the encore, I pulled it and the transition to the AA sled was seamless. I've recorded a couple of other shows since and all four lights were still lit at the end, the maximum was probably about 2.5 - 2.75 hours of run-time with two mics on phantom. I am pretty sure it would give me 8 or 9 hours on a full charge.

Now, I need to find those posts where people were recommending right-angle USB-C cables...

^ Risk? What risk? I have been running Eneloop Pros in the eight battery sled for nearly two years with no issues. After I saw Sebastian's post (http://taperssection.com/index.php?topic=189692.msg2298876#msg2298876), I figured a redundant power source might be a good idea. It was clear from the specs on the PowerCore 100000 PD that it would work and it does. I don't think I ever ran the AAs past the halfway point, so I have ample power with the Anker.

As for weight and size, I guess it depends on what *that* means. I almost always go to shows via train, usually with trams, buses and long walks on one end or both, and coupled with a hotel stay. So I need an overnight bag, plus my gear. To me, every pound actually counts and the larger Ankers don't even fit in the battery compartment in my Petrol.

i would guess it was designed for hot swap as it would be practically impossible for two indpendent packs to have the same voltage unless they were internally regulated

i cant remember the runtime for the L-batts but i do remember it being very long. long enough that 2 would get you thru a long day

doesnt mean you cant stagger them

all batteries last longer when discharged slowly (i.e parallel), regardless of chemistry

Title: DC to USB-C PD power option for MixPre 3/6
Post by: justme on August 18, 2019, 06:13:20 AM
I wanted to explore some of the popular DC to USB-C PD power converters that have begun to appeared this year.

It's a DC voltage to to USB-C PD compliant converter. There are many input connector option for them but I opted for the DC 5.5/2.5 model.
https://www.aliexpress.com/item/32946474518.html
It's recommended input voltage is 20V. And a max input of 22 volt.
Thats a bit annoying as packs of 4 li-ion cells might not be enough and 6 cells are too much. So DIY packs of 5 cells would be needed.

Anyway, I powered it from an external power pack using 4x18650 Li-ion pack with 14,8V output I can charge my Pixel 2 and a lot of other USB-C devices without a problem.
I then hooked it up to my MixPre-6 over USB-C and it booted perfectly. But shortly after warned me that the power source was not enough and wanted to switch to 4xAA-pack.
So I connected the converter to 20V DC power instead and that gave it enough headroom to supply the MixPre-6 with enough USB-C PD to make it happy.

The plastic case comes appart easy using the nails and the internals reveals a Chinese USB-C PD chip:

Manufacturer: Injoinic Corp
Chip: SOC IC--IP6527
http://www.sz-dowell.com/static/upload/ueditor/file/20181218/1545115664843095471.pdf

The chip specs states:
Input operating voltage range: 8.2V to 32V
VIN VIN=12V, VOUT=5V/3A, board end conversion efficiency 96.5%

But this did not appeared to be liked by the MixPre anyway. Or due to the way of the implementation of the chip in the converter.
I'll do some more tests but not using the Mixer as a guinea pig. :)
