Energizer’s Solar Recharger looks like an odd device. It looks like it could be an iPod battery extender, a AA charger or even a Solar adapter. And it actually is all of the above. Mainly, it’s a battery charger for standard rechargeable AA and AAA batteries and is primarily powered by an AC jack that’s assisted by a flip-out solar panel. The USB port can power your connected gadget and the Solar Charger will act as an extended battery for almost any USB-powered device, like your iPod for instance.
The beauty of this device is that through the use of cheap rechargeable batteries, Energizer sell it for just $50, with 2 AAs included. Some other features include weatherproofing and a rotating solar panel.
