USB Batteries

These are really pretty cool. Rechargeable batteries have been around for awhile, but these have a nice twist. Some engineer got pretty clever on this one. He has tapped into one of the useful features of the grand USB port. It's power supplication. That's right! He has incorporated the charger into the battery.

Here is the low down on these Badboys. When it is time to recharge, you just pop the battery top to expose the male USB connector. You don't have to remember  where the charger is, just find an available USB port. They are everywhere today; laptop, desktop,or USB hub. 

You can purchase them from ThinkGeek.com and thanks go out to Techzi.
