Most times our phone battery run down at the wrong time may when your trying to make that important call so you could plug it in only to find out that there’s no charger or no socket nearby. We’ve all been there and realizing this, Ampware announced the launch of CrankCase and CrankBox; a smartphone case with an integrated hand-crank generator and a universal generator, respectively.
Should users ever find themselves without power, they can re-energize their device’s battery, getting three hours of battery life for five minutes of crank time. Plug any USB-charged device into the charging port for a jump charge.
How does it work?
You unfold the crank handle and spin the handle. The handle is connected to a rare earth magnet dynamo generator which produces serious power to charge your phone. The generator is connected to your phone via a USB charging cable. You can use this short cable to sync to a laptop. Cranking the CrankCase gives you backup talk/text time when you have no access to wall power. As the inventors claim the 5 minutes cranking will be enough to power your smartphone for a 3 hours standby time or 15 minutes of talk time
The CrankCase also features a hidden, removable CrankCable under the crank handle which can be used like a normal cable in emergencies or when you don’t have one. Plus the phone can be charged with regular cables without removing the phone from the case. An option for all smartphone/mobile device users, the CrankBox will also be separately available to charge any device using a USB connection.
