Octopus battery charger sucks up to iPhone

The Octopus is an external battery-pack for the iPhone, with a neat trick. Instead of just hanging off the dock connector and sliding out just enough to disconnect, it has suction cups that stick the pack onto the back of the phone.
These suckers are just like those on an octopus’ tentacles, just not as tasty – hence the name. The battery pack connects to the dock-port via a flexible cable, and takes around three hours to fully transfer its load of electricity into the iPhone. One juiced, the iPhone will be at roughly half-power, able to play video for 10-hours or offer four hours of talk time. The Octopus itself charges via a USB-cable.

Why use this instead of a combo case and battery? Because it only needs to be used in emergencies. Those battery cases add bulk to what is a pretty slim and pocketable device, whereas an emergency battery can be kept out of the way in a bag until needed.

The Octopus is pretty cheap, too, coming in at a shade under $30.
