Powerstick

Wouldn't it be great to have an extra portable power source for your gadgets that didn't take up much space and was easy to charge? The Powerstick ($70) is a thumb drive-sized accessory that charges via the built-in USB connector and can provide extra juice for lots of different devices, including most cell phones, iPods, and others that charge via mini-USB. A simple fuel gauge graphic lets you know how the charging is going and how much power you have left. Genius.
