    How can I make a usb mobile phone charger ?

    Re: usb mobile phone charger Very simply you could just use a Zener diode resistor arrangement. You can sink upto 500mA from USB port. So get a zener for the voltage needed to charge the phone. Set up as follows VCC--Resistor---Zener---Ground. May work Only took 2seconds to dream up :angel:
