Home Made Mobile Phone Charger


Recommended Posts

Hello Everyone,

I am trying to build a mobile phone charger (For my Samsung phone) by myself using following components.

  • Step down transformer (from 230V to 9V 1200mA)
  • Bridge Rectifier
  • 1000uf capacitor (To smooth the DC voltage)
  • 7805 Regulator (To get output voltage 5V)
  • A micro USB cable I got from a broken charger.

Appreciate if you can share your thoughts regarding this.

Will this harmful to the phone or will this work better than the low quality Chinese chargers?
