I've been using a Brunton solar panel to keep my lights charged up when I'm away from the wall. It really makes a rechargeable light into the ultimate illumination tool and travel companion. As long as the sun shines during the day, you can run your light at night. Backup batteries? Bah! The sun is my backup battery. Okay, I carry one or two spares, but I don't need a bag full.
Get rid of: the expense of tons of disposable batteries, the waste of throwing them away, the weight of carrying them, the hassle of finding batteries in foreign countries, worrying about rationing your battery power, the need to rely on the wall or a store being open to make sure you can see when it gets dark...and I promise it will :)

The cool thing about the Solaris is that it's got a USB port...so you can charge any USB device you have, like your phone, tablet, camera, whateva.
