Use an Octopus to Charge Your iPhoneS

If you're always draining your iPhone battery on the go and don't want one of the case/battery combo packs (maybe you REALLY love your existing case?), the Octopus might be for you.

The supplementary battery pack sticks to the back of any Apple device with a 30 pin connector, adding four hours of additional talk time to the iPhone. And it's only $30. [Chinavision]
