Moxia have come up with a genius idea of making a battery that can be charged via USB. The batter is an actual AA battery with the top part which flips open to reveal the USB connector. Just plug the USBCell in to your PC/Laptop and it will charge. They cost around £12.99 for a pair which is not bad considering you do not need to carry around a battery charger.
The down side of the batteries are that they are not as powerful as rechargeables which are already lower then regular AA batteries. Still, I think this is a good idea and very handy to have a couple of these around in emergencies.
Where in the Detroit, Michigan area can I buy the USB Cell batteries? or can I only get them online?
