Have you ever run out of batteries, or unexpectedly found a need for a flash memory drive after the stores were closed? With this clever combo unit, you'll never find yourself short of memory or power at the worst possible moment.
The AA USB normally looks like a regular rechargeable AA battery, but twist it like a lipstick and a USB connector pops out of the end, letting you use it as a 4GB flash drive while recharging the battery.
This seems like a pretty clever idea, although most of the battery powered devices I use need at least two AA batteries. For now it's just a concept.
