Hand Crank Mobile Phone Charger
Intro: Hand Crank Mobile Phone Charger
This is my first instructable
I made this for my HTC wildfire which charges from a 5v power supply
al you need for this project is:
1 x handcrank tourch
1 x phone charger USB lead
all you do is replace the LED connections with the + / - wires from the USB lead and its done
or even better you can wire it to a female USB lead and charge anything USB

It doesn't work on mine, did you just cut the connections on LED's and replaced it with the wire from USB? And what wires are to be connected?

I have a variant of a solar powered charger case that I've a temporary patent on. The solar panel pushes 8 volts easily at over 5mA. In direct sunlight, it can recharge a Galaxy S3 in a couple hours. Even some clouds are ok, as most cell phones need only 4.8 volts to charge. The prototype is bulky and not very visually appealing, but it works.
