USB POWER SOLUTION
Charging AA batteries while on the road can be a hassle, as you typically need access to a power outlet and a specific recharging cradle. One interesting solution to this problem is USBCELL's USB rechargeable AA Batteries. The NiMH battery can be used like any normal AA battery, it has a 1.2v 1300mah battery and can be recharged simply by plugging into a USB port. An intelligent USB charger is built into the battery. There is no need for cables or separate charges, just lift the USBCELL's top cap and plug into a powered USB port.
