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.

No reason not to use low power mode if it works for you.

I get full power (green bar) with this battery:

and this cable:
https://www.amazon.com/gp/product/B01GMZP2I6/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

with my MixPre-6.

The battery and cable are color coordinated too. :)

I have the same battery and a white one.  Over 8 hours on each.

That's a pretty compelling battery for $20 compared to the Anker. I'm in for one.

I recently picked up an Anker PowerCore 10000 PD 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...

Why risk it though? It not *that* much bigger/heavier to use the 20k or 27k mah batteries, plus you can have all day confidence.

The 26,800 mah batteries are on sale again. Good price with nice quick charger.

^ 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, 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.

was doing a battery test on mixpre (4ch phantom, 96K), it ran for 10 hours on a 20100 mAh Jackery battery (still had 1 out of 4 lights when i pulled it, might have had a little more.

thats more than ive ever recorded in a single day, i think a 10000 mAh would be more than fine for my needs since id always be running a battery sled in case of usb cable issues

prime deal on anker 10000 mAH usb-C battery, with free hard case

https://slickdeals.net/f/13221406-prime-members-anker-portable-chargers-powercore-13000-25-more-free-shipping?src=frontpage&attrsrc=Test%3ABestDealsYouMissed%3AControl

EDIT:
has 4 lights to indicate battery level, running mixpre6 with 6 inputs and 4 channels of phantom:
4/4 lights lit: 2 hrs
3/4 lights: ~+1:15
2/4 lights: ~+1:15
1/4 lights: ~+1:00

so a safe 4-4.5 hours with that little guy at max load, prob quite a bit more w/o phantom

got a pair of those batts today. no issue on full power to the unit

the free hard cases were unnecessary imo for a battery but a good fit for smaller recorders like r07 and A10

Perhaps this has been answered before...

Question regarding the dual Sony L-series sled: does the sled draw equally? Or is it a hot-swap option?

If memory serves from the SLA days wiring batteries In series meant more run-time.


Just trying to figure if rotating batts on li-on chemistry is due diligence....

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
