That's a bit too steep just for a powerbank ;-)

  If you have a gasoline car you can charge in that from the starter battery. A starter battery is about 1kWh. Or just keep a lead acid battery around charged up and connect a ciggarette lighter socket to it.

    I was specifically curious about dedicated powerbanks. This discussion got sidetracked to cars.

      This one isn't intended for cars, but apparently is powerful enough to be able to recharge one, and popular youtuber Bitluni modified it to do just that. https://www.anker.com/eu-en/products/a1770 https://www.anker.com/eu-en/products/a1770 https://www.youtube.com/watch?v=ZE447r1mFXM https://www.youtube.com/watch?v=ZE447r1mFXM
