I know this thread is a couple of years old, but I've had it bookmarked for when I was ready to seriously start shopping. Since electronics so quickly change, I'm wondering what folks are using these days for solar charging. We have an iphone, ipad, and camera batteries that will need charging over a month long ride. We'll be staying half the time camping, and half the time in motels. So, we need the options of solar as well as plug in.
