The problem with wanting to bring your tunes to the beach, campground, slopes or trail, is that you either need to find a really long extension cord, or bring along a Sherpa to carry all the batteries you'll need.

So Etón, a leading emergency preparedness company and creator of green-powered electronics for outdoors, gives us the Soulra. It's a new portable sound system for iPod and iPhone that features a large, high-efficiency solar panel and a rechargeable lithium-ion battery that delivers power to simultaneously charge and play your iPod or iPhone, no matter where you are. Even if you're not outside. On a full sunlight charge, the Soulra will play music for up to four hours, and an additional 2-3 hours of play if you keep the solar panel open. The battery charge indicator will let you know when you need to recharge in direct sunlight. Or, if the sun is nowhere in sight, via an AC outlet.

Besides the convenience of not needing batteries or an outlet, the Soulra's got a rugged rubberized and aluminum exterior, designed to withstand the outdoor elements. Plus its case is splash proof and the speakers are sealed on the inside, providing protection from sand, water and anything else Mother Nature decides to throw your way.
