Using a Powerbank with RPI Player
I'm not sure if this has been covered before but I thought I give my impression of using a battery power bank with an RPI player.
My particular player is the Allo Digione HAT in conjunction with the latest RPI. Not sure if this makes it more juicy than just the Rpi alone but thought I'd mention it anyway. I run volumio and i play music equally from Tidal (via BubbleUpnp) as I do FLACs from a portable HDD plugged directly into the Rpi.
The power bank I'm using is the Anker 20100 which is also it's capacity mAH or 72.36 Wh. This outputs 5v - 4.8A to 2 x USB sockets.
I haven't been using it this for long, initially I had a cheap wall wart but it just didn't sound right to me. There was too much interference for want of a better word. Moving to the Anker gave an instant and maked improvement. Much lower noise floor and let's just say it sounded better.
My main reason for this post however is that the power bank is lasting far longer than I expected. I listen in blocks of between 2 to 4 hrs. The Anker has 4 battery level lights and I am losing a light every couple of sessions. Let's say each light is lasting between 4 - 6 hours it looks like i should be getting anywhere from 16 - 24 hours listening on a full charge which suits me just fine. I charge the Anker overnight and it's fully charged by morning.
Has anyone tried a Powerbank type battery with their Rpi player? I was about to purchase another linear psu but i don't think I will now well at least while I can put up with plugging-in/unplugging/recharging it
