Topic: Mix-Pre 3/6 USB Batteries (what works and what doesn't)

LIVIN ON THE EDGE!

Living on the edge is powering with USB and not even bothering to slap the silly 4xAA sled on there.

I bought one of these! 

https://www.bhphotovideo.com/c/product/1382309-REG/hawk_woods_sd_2_mixpwr_sound_devices_mix_pre.html

I had the SD version that is hot swapable.  I prefer the L mount batteries, but didn't like that the mount off the side.  The Hawks-wood is much better for mounting, but not hot swapable.  I have some really high mah L series batteries and just switch them at set break to be safe.  I also bought the Hawks-wood battery sled used and got a killer deal. 

semi-off topic, but now that i started using L-series batts on my zoom, i wouldnt hesitate to use them on the mixpre instead of the 8-AA sled. (i really dont consider the 4-AA sled all that useful except for as a backup power source

considering 8-AAs are around 5000 mA at 5V, almost any decent pair of L-series batts in the 2600-3000 mAh range should match or beat them on run time, and they are hot swappable unlike the AAs. and they make some big honkin ones as well, upwards of 10000 mAh, which could easily replace a usb-c battery without the cable fears

we'll be testing a bunch over here: https://taperssection.com/index.php?topic=193221

ill circle back with recs, but i no longer have a mixpre. if anybody has an L-series mount i can pass a pair of known-good batts along to try, in a bit.

hey J bell if you wanna test some L-series batts i can send some along that we have metrics for, on the zoom

I bought one of those Hypergear batteries a lot of people are using (the red/black one 12000 mAh). Broke out the MixPre-6 today to record some vinyl at the battery is completely dead. No power. Won't charge.

Looking for a more reliable (and maybe smaller) option.

I need to get through a normal night of Phish where I can just leave everything on and get though a single night...so maybe 6-8 hours of on time.

Entirely USB-C would be ideal.

Any good current options?

Oh, oh I need to check my battery too.

kep your li-ions disconnected and at about 40% charge in a cool space and they'll live a good, long life

I use the Anker 20100 mah PD+ packs and have never had an issue, besides once where I forgot to press the button to supply power via USB-C. They easily last all day at a festival.

I picked up one of these on cybermonday for $20.  even smaller and lighter than the Hypergear.  testing at home with 2 channels phantom I got about 7-7.5 hours.  I never run more than 2 mics + sbd so this should be fine for me.

Hypergear 12000 still on eBay for a good price. $21 OBO. I have a bunch and love them.

I'd been wanting another Anker 20100mAh PC+ USB C power bank, but they have been sold out for several months online. Bit the bullet and went ahead and got the new Anker 26800mAh PC+ PD 45W USB C on sale black friday for about $100, ran it for 9 hours on my mixpre 6 with 2 mics using phantom and 2 mics run off their own power supply and the power bank still showed half of the bars left.

I don't know how applicable it is to the 3 and 6, but I just managed to get my 10 II to run off of a dual output USB A battery. I haven't tested the limits of this method yet, but it's more of a novelty on my way to powering it with 9V DVD batteries. I imagine similar methods could be applied to the 3 and 6. You can check out my progress here: https://taperssection.com/index.php?topic=195943

The battery I am using to test on is applicable to the 3 and 6, though. I'm using the USB A outputs for testing but it does have a USB C PD output (I think it's 65W). It's a battery shell from China, model QD188-PD. It takes 8X 18650 cells and they are user removable (although swapping them messes with the capacity reading until you charge again).
