USBCell is best known for the AA USB rechargeable battery, but their product line doesn’t stop there (actually it does, but read more). USBCell also carries a 9 Volt rechargeable battery and a USB mobile cell phone rechargeable battery unit.
Albeit the recharge time is considerably slower than traditional options, the idea of reducing cords and dock stations along with the convenience of USB, makes the purchase well worth it.
At this time the product line is in build-out mode. The 9 Volt and cell phone rechargeable USB batteries are not yet available, but pre registration is just a click away.
