You never can tell when an emergency is going to strike, particularly in that day and age where most of us carry gadgets that require battery ability to run. The KeyChain USB Emergency DC Battery Charger could come in handy, as it will clamp onto any tiny lithium ion battery as found in digital cameras and cellphones, charging them by drawing potential from an available USB port. Heck, you can plus pick up an optional mains-to-USB converter just to invent certain you’ve got all grounds covered. Expect to fork out $11.90 to $14.90 for the KeyChain USB Emergency DC Battery Charger.
