Well, you wouldn't need the sun for one.

I'm always surprised that camping, and other outdoorsy, tools (i.e., flashlights, headlamps, satellite communicators, GPS, etc.) are increasingly powered by li-ion batteries. I think it's because there is currently an "ultralight" trend going on in the backpacking world, but it's still very annoying. When I go out, I just make sure everything, except for my Kindle, is powered by AA(A)'s. This way all I need is a dry bag with some extra non-rechargeable batteries, my battery charger, and solar panel.
