A power inverter converts your car's direct current (Dc) battery power into approved alternating current (Ac) power which can then run a range of household products such as microwaves, power tools, Tvs, radios, computers etc when an Ac outlet is not available. Particularly useful for camping or long road trips.
Just connect the inverter to your car battery, and plug your Ac devices into the inverter and you've got power on the go. (Smaller inverters will connect directly via the car's cigarette lighter)

The Technical Bit...
Two factors determine how a power inverter works: wave production and wattage output. Wave production describes the corporeal appearance of electrical signals as they move over an oscilloscope. Quadrilateral waves appear exactly as their name specifies: like squares on a grid. Pure sine waves, also called true sine waves, appear as illustrated waves on the screen.
How do I know which Inverter to choose?
The first step in choosing a power inverter is to match the inverter to the voltage of the battery you'll be using for power. In the majority of cases, you'll be using a appropriate 12-volt car battery, so you would want to opt a 12-volt inverter.
The next step is to recognize which devices you plan to power with the inverter. Each gadget should carry a label which that tells you the wattage it requires to operate. The wattage rating of your inverter must surpass the wattage of the top wattage gadget or the total wattage of all the devices you plan to run simultaneously, or of the largest device.
Some devices draw a higher wattage than their general operating wattage rating when they first start up. This is known as peak or surge, and this information should also be listed on the device's label. Most power inverters also have a peak rating, so make sure the inverter's peak rating is higher than the peak wattage of the gadget you intend to power. Microwaves are a extra case. As an example, you may know that your microwave is a 400-watt microwave. This is authentically the cooking wattage. The power wattage might be twice that amount. Again, check the label on the gadget to make sure.
Power inverters which run straight through your car cigarette lighter are designed for lower wattage devices - laptops, phone chargers etc. In fact, if you try to pass more than about 400 watts straight through a cigarette lighter connection, it will fail -- and it might even start a fire in your vehicle.
