USB Cell Battery

We have covered USB battery chargers before here at Everything USB, but why bother with a charger when you can just plug the batteries themselves into your USB port for charging? That’s exactly what the USB Cell batteries allow you to do, flip the top of the AA size battery back and you find a normal USB port.

*Built in intelligent charger,charge by any powered USB.
*Also can be charged by approved Chargers, no need take off the cap
