Chargers? We don't need no stinking chargers!

In the "that's so neat - there must be a catch" category, a "AA" battery that flips its top to reveal a USB connector............ to recharge the battery! Let's face it - if you've got technology around, you've got plenty of USB ports to plug these things into. USBCells have their own indicators to tell you when charging is complete. You can charge many at a time if you have a powered USB hub. You can even use a standard NiMH battery charger if you've got no USB ports around.

They're only available in the UK right now, but I have a feeling that will change real soon.
