Reactor Hand Crank iPhone External Battery Case Lets You Recharge it Without an Electrical Power Source
Here’s one external battery case for the iPhone that comes with an additional way to juice up besides taking power off the grid, one that comes with a hand crank that lets you recharge the external battery use hand power.
The Reactor from Gridcase is a hand crank external battery that works just like a typical one does, which is to provide additional battery power on top of the one available in the iPhone. However, with a hand crank, it can be recharged in emergency situations where there are no electrical outlets available. However it still takes quite a bit of cranking to get a decent amount of talk-time; 5 minutes of cranking will get you about one minute’s worth of talking time on mobile phone.
Not only does it provide protection as a casing, it also provides power, and is able to be recharged using pure clean energy, which is an interesting option for eco-minded folks who own an iPhone.
