Step 6: Results

Picture of Results
It took about 3 hours of cranking, but I got my phone fully charged.   The phone only accepts a very small current (about 94mA in my case), so it's not hard at all to crank.  But if the generator leads are shorted out, or hooked up to a re-chargable battery, the effort to crank increases quite a bit!  This is because you're pushing more current.

In retrospect, I think it would have been more efficient to spend 15 minutes cranking a larger current into a large 6 volt battery, and then charging the phone from that.  But hey, you do what you can with what you have.  

The charger illuminated an incandescent flashlight bulb, a super bright white LED, and there was even enough power to convert water into fuel with the OxyHydrogen generator made in a previous project!
