Rechargable batteries have always been a more cost effective and eco-friendly alternative to non-rechargable ones. However when we do run out of batteries, say when we’re on a trip for example, it often isn’t so easy to find battery chargers lying around.

These USBCell USB rechargable batteries make our lives so much easier as you can just uncap them and plug them into your nearest computer or laptop to recharge them to full power. With a laptop around to boost some emergency charge into your batteries, you won’t ever miss the golden shot on your digital camera when your battery life is gone. Thanks to ThinkGeek again for stocking in such neat ideas.
