IOGear Emergency AA Battery

This version of a USB battery by IOGear is pretty nifty. One end works as a miniUSB plug, allowing you to easily charge your cellphone, MP3 player, digital camera or vibrator when you’re in dire need of some juice. The Gearjuice Rescue Chargers is a steal at $12. The next time you break down on the side of the road on some cold, rainy night and your cellphone doesn’t work, you’ll be wishing you had one of these.
