USB Rechargeable Battery AA

A USB rechargeable AA battery…ingenious. The USBCell’s flip open top makes for an easy transition between using the battery or recharging.

Sadly, the USBCell is currently only available in the UK (lucky Brits), but should be available to other places throughout the world in the near future.

A pack of two runs for around $18. A little steep for two batteries, but totally reasonable for two batteries that are this cool. A perfect gift for that gadgethead friend of yours.
