Hello all,

This is my very first instructable! I have made a machine using a motor, some electronic components, gears and pulleys to very efficiently convert the kinetic energy from a persons hands into electricity. This can produce, at fastest speed, up to 12 volts, but it is controlled at 5 volts because I made it to only charge mobile devices. It has unlimited potential as more gears are added, and a bigger motor is used. It can also be connected to a bicycle or car wheel to produce amazingly high amounts of electricity. About 10 - 15 minutes of spinning would get your smart phone or tablet charged up to 40% - 50% if the product is built correctly. Good luck, and enjoy.

Sorry for the inconvenient format. All instructions are written in images. All the instructions are very clear and easy to follow.

Here is a video showing how it worked out at the end.

It would be nice to upgrade and install thіs invention on a bicycle or something like that. It would be cool!

5volts 100 watts means 5v at " 20 AMPS " did you wish to fry up your phone. Or does it mean 100 mA ?

A few details:

Most chargers are about 5 watts, where does 100 watts come from ( and note, current is amperes not watts, watts are units of power )? A good athlete is good for only about 250 watts, for modest periods of time.

It looks like only the cell phone battery stabalizes the voltage, is this correct?
