Thinking about buying one for a trip I'm going on, then to also use as a power source for my mobile Raspberry Pi project.

Is it realistic to expect to be able to actually charge a 10kmah battery from a tiny solar panel? My assumption is that it's more of a gimmick or might be able to just top up a battery to keep it from self-draining, but I'd be surprised if it could charge the 10kmah internal battery in a full day of sitting in the sun.

Get something that uses replaceable 18650 batteries.

I have no idea what that is, nor why I'd want it.

18650 is a 2500 mah battery type. Looks like a big AA.

Its replaceable. So when the cells don't hold a charge that well just replace them instead of the whole box.

I carry this one so that I don't have to screw around with cords.
