It may seem a little nerdy, but I think solar-powered bags are pretty cool. In fact, I would proudly carry this Solar Powered Messenger Bag, secure in the knowledge that my gadgets would be charged as long I had sunlight. I’m sure it’s a great conversation starter, too, since they’re still fairly rare.

If the Messenger Bag isn’t your style, they also have a Solar Powered Backpack, which is probably a little better on your back, especially if you carry heavy loads. The backpack is $230 and the messenger bag is $240.
