This schematic shows you how to build power inverter 12-V battery to 220 V. You can use it for mobile inverter power supply whether in the car, boat, caravan or motor home. When it comes to grid independent operation of simple electrical appliances, such as lamps, soldering irons and small electric tools is a simple inverter circuit is sufficient. Six transistors are enough, as the circuit presented here.
Caution: since it produces high voltage, DON’T build the project if you don’t have any sufficient electronic knowledge
