Generally, we use a 5v adaptor and a data cable to charge our mobile phone. But sometimes u have a low Ampere adaptor that does not give proper charging to smartphones.
Here we created a Circuit through which we can charge our mobile phone faster than any other adaptor.
What is USB Mobile Charger Circuit?
USB mobile charger circuit is a type of mobile charger that takes power from the USB socket. As you know the USB socket gives 5 volts at the output but the amount of current in it is very less.
But this USB mobile charger circuit gives 2 Ampere current at the output. We create this circuit with easily available electronic components. You can find these components in any old scrap circuit.
1) Male USB Jack
2) 1k, 560ohm Resistance
3) 2x 100uf, 16v Capacitor
5) TIP42 Transistor
6) 1n4007 Diode
7) 4.7v Zener Diode
