A case with which you can charge your mobile

The proposals in gadgets to maintain the autonomy of mobile phones continue to germinate. And it is that in addition to the already known external batteries, CrankCase now appears, a device with which specifically applying human force, turning the crank that incorporates- is capable of charging the mobile, at least for a 5-minute call.

Regarding the characteristics of this terminal, it should be noted that it is presented as a case compatible with iPhone 5, 5S and 6. The aforementioned crank that can also function as an arm to support the smartphone – is connected to a dynamo that takes advantage of the USB connection of the device to charge it and with it, make an emergency call or send messages.

Now, it is necessary to investigate that with CrankCase, there is also the option of CrankBox, whose appearance and function point to that of an external battery. Unlike the case, it is compatible with various terminals regardless of their OS- that have a USB port for charging (from smartphones, tablets and even smart watches).

Before finalizing, it should be noted that both products have been presented on the Indiegogo crowdfunding platform. At the time of writing this note, the collection had already reached $ 38,678, of the $ 50,000 that is the goal.
