Kensington have just added a new PowerLift back-up battery pack to their range that is slightly different to the run of the mill combined case and battery solutions.
The new Kensington PowerLift Back-Up is equipped with a 1200 mAh battery that Kensington say will add an extra 20 more hours of music playback, 5 more hours of video, 3.5 more hours of talk and even an extra hour and a half of FaceTime to your iPhone usage. Watch the video after the jump to see it in action.
The Powerlift has a handy kickstand that allows you to watch video and use Facetime hands free, however it will only support a portrait mode. But you can also use the battery pack in your hand rather than in a docking formation if desired.
