CrankCase: Power Generating iPhone Case

CrankCase For Apple iPhone

AMPWARE has developed a new charging technology for your iPhone or iPad. The CrankCase and CrankBox are two different portable batteries with a hand-turned crank.

The CrankCase is a smartphone case with an integrated hand-crank power generator, generating power from a biomechanical cranking cycle. The more you crank, the more power is generated and delivered to your device. 5 minutes of cranking will get you enough juice for three hours of smartphone use or half that for a tablet. (See chart below)

Crank time for Charging Battery

The CrankBox, is not a case, but it features a USB port to charge any smartphone or USB charged device, all you need is a cable.
