    1.5 A for 10 h is 15000 mAh, at 12V. Current powerbanks can do that. Here is a redmi one, specs says it can do that, 20000 mAh, 12V is the maximum: https://www.mi.com/global/product/20000mah-redmi-fast-charge-power-bank/specs

    Buy an usb-pd 12V cable, one end of the cable is type c, the other end is standard dc coax. The cable has a chip inside, so it will always ask for 12V from the power source, it’s like 5 USD, I have one for a similar usecase, works perfectly. They work only if the source can send the required voltage, if a powerbank can only send 5V or 9V it cant convert it up to 12.

    It should look something like this, make sure the voltage is correct before buying:









  • My offline android music workflow:

    • Server: Navidrome but any music server supporting Subsonic API would work here. Navidrome has a nice UI, and reads MusicBrainz IDs, and can scrobble to ListenBrainz, that’s why I settled with this.
    • Mobile app: Ultrasonic, on Fdroid. There are a lot of ways you can set up caching. I set up that it should automatically download everything from my “Now playing” playlist, at home on wifi I just add a bunch of albums and playlists to the “Now playing” list, it takes a while but it transcodes and downloads everything in a couple of minutes. It has very good Android Auto support, and a widget. Due to an annoying bug I had to downgrade to version 4.7.1, but otherwise I love it.
