Mobile phone wind generator Answered

Hi
at school, I am making a mobile phone generator. It's only GCSE so my apologies for my lack of knowledge. It is meant to be a "wind generator" but it can basically be a renewable generator via motion. So since I get to take it home afterwards I designed it to be a little record player where you turned the platter and it would change a phone. This is where I need some help. Would this 24v motor provide enough juice to charge a lithium ion battery (with a boost or buck converter [if needed to step down to an appropriate voltage] then a constant current protection circuit etc) the output 5v to charge your phone?

Here is the motor:

Thanks!

What matters is the nominal power consumption of the motor at the specified voltage.
If you match this speed you will be pretty close to the input voltage.
To charge a phone half decent you not only need around 2amp available but also the right voltages on tha data lines - I wrote something about this but Google will tell you what you need.
