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.

Tested twice with a usb C to A cable.  No errors and it gracefully switched to the internal AA when the usb battery died.  Going to test again just to be sure.

So if you use the Anker C to C cable that comes with the battery you didn't have the issue??  Thanks for the info

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.

hmm, interesting. I ended up ordering the Anker 26800+ PD version, which comes with a USB-C to USB-C cable. i just figured since I was avoiding the whole USB-A amperage issue, I would be good. i hadn't considered that the included cable might not work. can you be more specific as to how the USB-C to USB-C cables included with Anker batteries have been reported as troublesome? I don't recall seeing that in this thread, though I might have just forgotten the specific post by now.

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.
