There are two different types of power inverters: modified sine wave and pure (true) sine wave inverters. The difference between the two types is how close the output power replicates standard AC mains power.

A pure (or true) sine wave inverter is far more complex than a modified sine wave inverter and is similar to household power. Modified sine wave power inverters are more common due to the fact that most electric appliances do not require a true sine wave power source. If your not sure check with your devices manufacture. True sine wave inverters are used for computer, laptops, cameras, tvs, etc..
