While watching a friend's YouTube video the other day, I saw this cool little solar light that also has a USB charger. Not the most powerful, but looks like a cool addition to a smaller, PSK type of set-up. I'm never very tech heavy, but I think I might pick-up one of these.

It's a neat little kit he's showing off, but if you just want to see the light, skip ahead to 5:22:
