Recharge your smartphone with DIY hand crank charger

A couple of weekends ago I went camping with my son and ran into a bit of a problem with my Android phone. The phone was getting dangerously close to going completely dead and as it turns out there are no plugs located on any of the trees in the woods. Luckily, I was able to make it through to the next morning by turning off all non-essential functions such as GPS, Bluetooth, Wi-Fi and background data communication. Now it seems I may have another option thanks to a new video on YouTube.

Benjamin Heckendorn recently celebrated 10 years of his work on the web and his latest contribution is sure to turn the head of more than one Android user. In a posted YouTube video, Heck demonstrated a do-it-yourself crank mobile phone charger he made by taking apart a hand crank powered flashlight. As it turns out, the crank mechanism is capable of generating five volts of power which is just enough to recharge Ben’s HTC EVO.

Now in the video Ben makes it sound like this solution will only work for Android phones, but if you think about it most smartphones are capable of being recharged through a USB port. A USB port provides five volts of power which is why the crank worked with the HTC EVO and should work with practically any smartphone.
