USB Powercells Recharge AA via USB

Posted by Chad Criswell Aug 13, 2008

Buying rechargable batteries is a great way to help conserve resources. Instead of tossing used batteries into the trash bin you can recharge and reuse the battery dozens of times. The problem with such batteries (until now) is that you had to carry around a recharging station with you otherwise you would be left with no other option than to go buy a new set of dry cells at the local convenience store. With the USB Powercells you never need to worry about taking along a charger, the charging mechanism is built into the battery itself!

By flipping open the positive end cap on a USB powercell you expose a standard USB device connector. By plugging that connection into your computer the computer will then recharge the NiMH battery to full power in an hour or two. The web site claims that even a short recharge will allow you to power your AA devices for several hours. Cool!
