Emergency Mobile Charger using DC motor

4 tools

This is a hobby project which can be made by anyone following some very simple instructions. The charger works on the principle of DC motor being used as a generator converting mechanical energy to electrical energy. But since the voltage required by a phone is 5V a voltage regulator IC 7805 is used to get the desired output voltage from the DC motor
