A USB rechargeable battery
By now you know the routine. Wherever you are, there you’ll eventually need to plug in. It’s the first rule of technology ownership. Being connected means, well, connecting. But now you’ll need to connect less frequently with USB batteries. At a glance it may seem like this is a version of the creative USB – a flash drive that looks like a battery. That is until you realize, it really is a battery. Use it in pointers during presentations, wireless keyboards and mice, digital cameras and other personal devices. 
The USB batteries are available in AAA, C, D, 9V and mobile device sizes. They’re rechargeable from any USB port on a computer, game station or other powered USB. Just a little charge time yields a lot. An hour charges it up half way. Plus these are not just batteries, they’re a fashion accessory. The company plans to release a line of pastel colored batteries. Okay, so the USB battery won’t really free you from the hunt for the next available outlet at the airport, but they’re said to be environmentally friendly and at the very least, they’re cute.
