3.7v to 220V inverter circuit diagram with Mobile charger transformer. In this project, we are going to make a very easy & simple low power inverter. We have used various electronic-components to make this easy & simple project.
Even this project can be made with scrap electronic-components available at your own home. Inverters are used to convert DC current(the word DC stands for direct current) into AC current(the term AC stands for Alternative current).
An inverter circuit is used to alter/change the DC power to AC power. You can make this electronic-project without any problem or hesitation but it is an experimental electronic circuit

Rechargeable 3.7 v To 220v Inverter Circuit Diagram With Some Modifications
This is modified Circuit with Rechargeable Facility. In this circuit I used 2pcs 18650 Batteries (2000mah each) in Parallel and used one TP4056 Module For Charging. This Circuit will give you 3-4 hour backup with 3Watt Bulb. I changed 100 ohm resistor with 56 ohm 1 Watt it will give you better result and more power but use Proper Heat Sink with Transistor MJE2955
