September 22, 2006 Logical, inevitable, perhaps even overdue in retrospect, our ripper idea of the day (at least so far) is this rechargeable battery that can charge from any USB port without the need for any recharging devices, cradles or cables. Just pop the end to reveal a built in connector and charger, plug into any powered USB port on your desktop, laptop, keyboard, games console, monitor ad infinitum charge the battery. Currently available in the AA format, the USBCELL will shortly comprise a full range of standard formats, phone and camera batteries.
