    I have these battery packs that magnetically stick to the back of my phone and charge it. Just slap it on and forget about it.

    It makes my phone hot and wastes a lot of power (I can also charge from the same battery packs using a cable, and I get noticeably more charge).

    But it’s real convenient when you don’t want to worry about it. I use them at conventions or when I’m out hiking or skiing.

      Same. In winter it doubles as a pocket heater. Summer is worse, I wish electronics could also feasibly convert waste heat to cooling, but physics be like “yea, nah”.

        There are fans that attach to the backs of phones. Of course they use electricity as well.

        Clipping a sterling engine and a radiator to the back of a phone could be fun.
