Need an external battery pack that doesn’t just dangle from the foot of your phone like a bulbous, electrically-charged bunion? The Octopus might be just what you’re looking for.
Taking its name from the suction cups of a cephalopod’s tentacles, the Octopus sits in your gadget bag until your iPhone runs out of juice, at which point it can be slapped onto the back of your device and connected to the Dock Connector thanks to a flexible cable.
If you allow the Octopus to fully charge your iOS device, you can expect your iPhone to comfortably juice to about half power, which should give you either ten hours of extra video or four hours of extra talk time.
Not a bad idea compared to some of the bulkier combo battery cases, and cheap to boot: the Octopus will only cost you $30Related
