Bicycle Cell Phone Charger (Wind Turbine with build in Battery)

I go very often to cycle in the nature where is no electricity, and during a long bike tour my phone usually discharges. These smartphones have a large capacity but its consumption is big too. I made a few weeks ago another bike turbine for the Bicycle Contest, but I think I can make a better one. So created an all in one wind turbine power bank.

I like to combine cycling with electronics (these are my favorite hobbies) so that's why I create so much bike gadgets now for the Bike Contest.

This project requires basic soldering experience and
