I tried a USB-C 3.1 TO USB-C 3.1 cable for powering MP6 last evening and got zero power. Not sure if anyone else has had this experience.
What battery? I have found a few batteries that take USB C, and all of them have powered the MixPre 6 without issue. It sounds like a bad cable.

FWIW, Here are 3 USB-C batteries I use:

That's very odd. Any properly-designed USB-C to USB-C cable should do the trick. What brand is your cable?

Who is the maker of the cable?

I've used Anker 3.1 to 3.1 with great success.

I can confirm that this angled usb-c works perfectly with my usbpre-3, giving the green power indicator with both of the usb-c batteries I own. There is no wrong way to plug in a usb-c connector, so it is right or left angle.

Anyone have a usb c battery that doesn't provide a green battery indicator?  I bought the right angle cable above and with my battery I am not getting full power.  It is a vinsic 20000 power bank.

The USB-c port on that appears to be for input not output.

I found the other models. Offhand they should work but some of the reviews on Amazon bother me. I  see some suggestions that other people could not get the USB-c to act as an output, at least with their units.

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:


Question: Why wont it charge from the usb type c as output, its only working as input
Answer: Not enough information to answer the question depends on what you're trying to charge unit could be too small to charge this item or other factors could be part of the problem
By Robert Helms on April 2, 2017
I have come to find out that the power bank unit can't recharge through USB C. It will only recharge through Micro USB. It will give you a double 00 if you try to recharge your bank through USB C .
By The Amazonian on August 11, 2017
Mine has this same issue. I'm trying to charge a Nexus 5x from the USB-C output but it's not working. It only works as an input.
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 continue to have great success with this:

https://www.amazon.com/Anker-PowerCore-Ultra-High-Capacity-Portable/dp/B014ZO46LK/ref=sr_1_4?ie=UTF8&qid=1504744857&sr=8-4&keywords=anker+usb-c

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.

Capsules: Schoeps mk41v, mk4v, mk22, mk3 & mk8

When I'm powering from USB, I'd like to ditch the AA tray as well, but I'm worried about dirt and dust getting into the SD card slot.

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.

That's true. It does provide emergency back-up.
