The current battery technology won't be able to keep our phones running longer than we want to. So SOS Ready designed this pocket sized "SOSCharger," which is powered by you.

The gadget has a built in generator and all you have to do is connect your smartphone via USB connection and hand crank the handle. It has a 1,500 mAh lithium polymer battery and the company claims three to five minutes of winding it will give you five to 12 minutes of talk time.

SOS Ready premiered the SOSCharger at CES this year and their prototype is tested and complete. The company is hoping to raise $27,000 on Kickstarter to take the charger to full production, with shipping targeted for this summer.
