CES 2009 - Power up with solar

Harnessing the power of the sun to charge either 2AA or 2AAA batteries or just about any device that can be charged via USB, Energizer's aptly titled Solar Charger is a relatively inexpensive way to charge up with solar power. The solar panel manually swivels 180-degrees to get the best sun exposure and it fully charges 2AA batteries in about 20 hours. Sure, it's a bit slow but the energy it collects is free.
