We all know what a pain it can be to run out of batteries on the go, rendering our digital camera useless at the most inopportune of moments

Moixa Energy has just released a product that will make the NB-mate a bit less necessary: USB rechargeable AA batteries. The USBCell is a little AA wonder that has a removable cap at the positive end that reveals a standard USB connector. Simply plug this battery into a powered USB port and it recharges all on it’s own without the need to carry an extra power adapter/charger with you.

The manufacturer claims the USBCell take about 5 hours to charge to 90% capacity, and that “Charging for just a few minutes provides extra hours of instant use for most input devices.” The batteries are standard 1.2v 1300mah NiMH rechargeables and can even be charged using common AA NiMH battery chargers if you can’t spare any USB ports or happen to have an NB-Mate.
