An inverter is a device that converts DC power (batteries, storage batteries) into AC power (generally 220V,50Hz sine wave).

It consists of inverter bridge, control logic and filter circuit. Widely used in air conditioning, home theater, electric grinding wheel, power tools, sewing machines, DVD, VCD, computers, TV, washing machines, range hoods, refrigerators, VCRs, massagers, fans, lighting and so on.

In foreign countries, due to the high popularity of automobiles, you can use the inverter to connect the battery to drive electrical appliances and various tools. The car inverter output through the cigarette lighter is 20W, 40W, 80W, 120W to 150W power specifications. Larger power inverters should be connected to the battery through the connecting cable. By connecting household appliances to the output of the power converter, you can use all kinds of electrical appliances in the car. The electrical appliances can be used as follows: cell phone, laptop, digital camera, video camera, lighting, electric shaver, CD player, game console, PDA, power tools, car refrigerator, and a variety of travel, camping, medical emergency appliances, and so on.
