Now this has got to be one of the coolest ideas I’ve seen in quite some time. It’s a real AA battery that is charged thru USB.

They are currently only avaliable in the UK, but I am sure that there will be a US model soon. Price in the UK is: £12.99 which works to about $24.53.

Maybe a bit pricey, but I use usb all the time to charge my gadgets, what better way to use a usb port, but to also charge my batteries.
