For those of you who'd rather buy a packaged solar-charged battery solution, Voltaic Systems sells a 3000mAh USB battery/2W solar panel combo for around US$60+tax/S&H. (I have no connection to them aside from being a customer.) This version works only for phones, though. While they do have a solar-powered solution for some tablets like the iPad/iPad2, it's a LOT more expensive, requiring multiple solar panels.
