Partly a good deal(cheapest on net if you purchase 3 packs and apply google checkout), partly because I find the product pretty amazing! Rechargeable batteries with a USB connector inside the lid, allowing them to be charged anywhere with a PC - must be an excellent item for anyone needing to ensure their batteries last away from their own office!
The USB port is becoming more and more useful. First came the memory card with the built-in USB plug, now comes the USB-charged battery! Moixa Energy have developed the USB Cell as an environmentally-friendly alternative to normal AA batteries. The top of one side flips up to reveal a USB connector, and the battery simply plugs into an open port.
The convenience of the USB Cell means that you don't have to carry around a separate charger or cables, and can charge it in a game station, as well as in keyboards and monitors with USB sockets.
It takes five hours to charge one of the cells if it was fully discharged.
Because the batteries are fully rechargeable, you never need to throw them away, think of all the money you will save compared to when you buy countless amounts of regular batteries!
