You can use any 12 volt charger like routers, switches etc.

So let's get started...

Step 1: Circuit Diagram

Here it is the circuit diagram. We can build our tiny little converter with the help of this diagram.

Step 2: Components

You'll need

small piece of vero board

A candy box (you can buy your nearest candy shop)

Female usb port

12 volt female connector according to your charger

IC: LM7805

Capacitors: 100nf x 2 (non-polarized), 100uf (polarized) and 47uf (polarized)

Resistors: 1k and 470 ohms

Led: Red

Spst on/off switch

Step 3: Placing and Soldering Components

place your components according to circuit diagram and then soldering it very carefully don't forget to soldering a female usb port and a switch in a candy box cap.
