Here’s another emergency USB charger, this one powered by 2 AA batteries. Not a bad deal for under $10, and it includes a tiny built-in LED light for grins.
However, I can’t say I love the idea of using batteries. I’d rather have it either use a rechargeable battery or even better, be solar rechargeable (like the iTech SolarCharger).
