Something to convert it to 110 or 220 AC is needed which eats up a lot of power and is probably noisy.I'm interested in how long you could run on 13 kJ (convert to W-hr if you want, it is all energy).
Let's just look at the amp - what would the current draw be - roughly?
Going back to the Sonos Move as reference, they specify idle power at about 3W. So that would be the amp with the wireless. I think they use 18V battery and most likely a bridged Class D so they can possibly get close to 40W into 4 ohms. I guess running on higher voltage would generally mean a bit more idle power but maybe not much, and of course it depends on what amplifier.I'm interested in how long you could run on 13 kJ (convert to W-hr if you want, it is all energy).

Explain please.no conversion is needed
Are you wanting to run on 12V? The Aiyima that Amir reviewed (or any amp that similarly runs on an external power supply) would be easy to run from a battery: https://www.audiosciencereview.com/...ds/aiyima-a07-tpa3255-review-amplifier.18984/a DC amp or several can be used as with car amps

50 to 100 Amp-hr at 12 V DC ---->

Convert it to WH, Joules is W*s and it will be a lot of seconds.ok, let's go with 15 MJ
consider it a thought experiment, based on where audio is going
