The next time you head out to the beach to get a little bit of tan, why not bring the Scosche solBAT II with you? It won’t be able to massage your entire back with suntan lotion, but it is able to keep itself juiced up simply by basking under the sun, thanks to its built-in solar panel. The solBAT II improves on its predecessor by charging devices at a much faster rate, and can be mounted onto a window using suction cups (a clip is included just in case you want to hook it up to other places). Needless to say, while solar charging is an option, hooking it up to a USB port is a much faster method. The solBAT II will retail for $30 a pop.
