those usb rechargeable batteries are pretty sweet. never thought about a battery like that b4
When they first announced them in 2004/5 they were a big deal for a couple of months. Places like thinkgeek couldnt stop the preorders from comming in. The the reality of the battery set in on their release. People just dropped them like a bad cold. I had a pair (left them in a hotel on a trip to Germany a few years ago), and they werent bad. They just have a very short run time compared to standard recharge or normal alkies. They also have a longer recharge time compared to their run time. I found that they were a disaster for cameras (as the flash is a real killer) and to be honest, I cant think of anything that they are good for except emergency use if you have them on hand. Then again, they are only about half a battery. The other half is the USB charging system. From my use of them, I say they are on par with using AAA to AA converters. They have enough juice to work, but not for very long.
