Phone Charger Using a Computer Fan




Introduction: Phone Charger Using a Computer Fan

My First Project on Instructables!

This project has copyright to :

Thank you for this wonderful idea into charging a device.

I have not fully completed this project so there will be updates to images so I don't have to copy-Right the owners one in use but it will look similar just on a MOTORCYCLE....

Step 1: Parts:

All I used was:

  • 12V DC computer fan.
  • 5v step-up module, (bought on eBay)
  • An old iPhone 3Gs
  • Phone charging cable

Step 2: Put Them All Together

Put the fan wires onto the + and - of the step-up module. The RED fan wire goes to + and the BLACK goes to - .

I tested my fan charger by spinning it connected to the powered up iPhone and it worked!

Now to improve this project you could use a solar panel. This project can be used to charge many devices I was charging my walkie talkie via this module (the walkie had a PC charger).

NO devices that require 110 - 240 v may charge with this module. Maybe improve it more with a different step up module.

Thanks my first Instructables!

    Just out of curiosity will this work? by using 5v stepup module? if yes what is the time requires to charge the phone?

    Good idea. Built one. Getting a constant 5V out. The LED in teh step-up lights up. But not charging the phone. Maybe ampere is not enough?

    Simple and cool, I'm very excited about this project.
    A bit of curiosity: what speed do you need at your bycicle to provide 5v ~500mAh to charge a cellphone?
