What’s the power draw? If you can find a big enough power bank thing, put that between the wall wart and the pi. Just done it with my chromecast and it seems to have improved things
A new low noise SMPS in the pipeline from Allo, 5v3a I think, should be interesting to see how it pans out...

I've just tried my Pi + Allo Boss set up with a very cheap 5v power bank. I was skeptical that I would hear any difference, but the improvement was very noticeable. I went back to the switching power supply just to check, listening to the same well known track each time. Basically better definition/separation between the instruments.
For example, a piano track with a long low note using the sustain peddle - on the battery I noticed that it went on for longer than I had previously known before fading out. Going back to the SMPS, I could sort of tell that it was still there, but it was more difficult to detect (plus I knew that it should be there, so was listening extra hard for it!). I guess this is about a lower noise floor with the battery?
Anyhow, my question is for those using batteries - what is the most convenient way of doing this? Is there any way to avoid buying two battery packs and constantly recharging them/swapping them over? Can you permanently charge whilst using it to power the pi? If so, would that negatively impact on audio quality?
Any thoughts or recommendations would be very welcome at this point!
Think it depends on how much you use it and if you switch off after use. Ive been using a. Battery pack with my pi for almost ever. I have a charger with cable that I just plug into the pi when the % goes below 60 ish It's a 20k battery with a dig % output so easy to keep track of
Thanks Grant. Do you turn the pi off after each use? How often do you have to disconnect the battery to recharge, and how long is it to fully charge, roughly?
yes i power it down then switch off battery. I have an inline switch made up with micro plugs on so i just flick a switch. then charge can take a couple of hrs from 70 say. its a big battery . got it off amazon... they do bigger and newer ones now so ay well charge quicker.
