In Reply to: RE: Power Supply upgrade for Chord DAC posted by ppopp on March 27, 2024 at 10:59:32
Rob Watts seems to recommend battery power. You can get a 12V LFP 50Ah battery for about $150. I use one for my Qutest. I need to charge it
once a month. It is a real improvement.

Batteries aren't the perfect 'flat DC' power source some think they are.
Qutest requires 5V power supply, so you are putting a regulator on the 12V battery?
Sorry, brain fart at my end. The Qutest runs on NiMh batteries. One set last about two hours. Right now I have two sets together. The NUC runs on the 12V LFP. I'm not using any regulation on the batteries. The only AC on the digital side runs the monoblocs, each with their own socket.
Thanks for the info.
Do you have link to such a rechargeable battery?
See the link below. You get as many of these as you need for your regular listening sessions. Figure on up to two hours per pack. Get adapters and put all of them in parallel and then connect each set of cables together an put on whatever kind of power connection needed by your low power equipment. The Qutest will drop out when the batteries get down to at 4.4 volts.
