Topic: MixPre 10 II Power Options???

[dogmusic]

I've been running my MixPre-10T with one of these Krisdonia LiPos (via custom hirose cable), and it's been a solid workhorse! Both, slip perfectly into a Sachtler SN607 (small) Lightweight Audio Bag. BTW, I also always use the provided 8AA sled with IKEA brand LADDA rechargeables, as a backup...

Their smaller capacity model is TSA ok, so if you ever fly with your gear, opt for the smaller beast:

Highly recommend! I've used Anker and RAVPower products in the past, and these are just as reliable

What is the connector on your custom hirose cable to the Krisdonia? I ordered a Hirose to USB-C cable and was wondering if it could power my MixPre 10 II from the Krisdonia USB-C output at 12V.

I believe it's an m-tip on the battery output end. Built meticulously by Ted G. I run mine at 16V (always multiple  P48 pairs) and it's never failed

Thanks for that info. Does the m-tip plug go into the “DC-OUT” on the Krisdonia?

Thanks again. It seems like this Hirose to USB-C may not be a good idea.

You can order a Hirose to 2.1 tip (m tip) cable on amazon!  They are around $25ish.

Thanks for that. Do I have to worry about polarity on the m-tip or are they all the same?

I've used the Amazon cable without issues with my Mixpre 10 II

Do you have a link for that particular Amazon cable? TIA.

I used that same hirose cable for my SD 442. It was surprisingly well built.

I wanted to give an update on the excellent advice I received here. I got the Krisdonia 25000 mAh Power Bank thanks to SOS and the power cable thanks to jbell.

Tested both today with my MixPre-10 II. Two mics P48 on two tracks (no mix tracks) at 24/192 and got almost exactly 5 hours recording time.

I may have gotten more time if I'd removed the USB backup drive for the test. I don't know how much drain the additional writing mght be.

I had one question for SOS about his Krisdonia. Does the Display ever turn off? After I first charged the unit, the bright green display came on and has stayed lit ever since.

I've tried all ways of pushing and holding the power button but it won't turn off.

Anyway, thanks again for your help.

2023-07-20 UPDATE: It turned out my first Krisdonia unit was faulty. After replacement, I got just over 9 hours recording time with the same setup as above, but without the USB backup drive.
