A Battery Power Inverter is used to transfer DC power from a battery (preferably a Deep Cycle Battery) to AC power, enabling a battery to power all sorts of devices such as; Radios, TV's, Microwaves, Computers/Laptops and other such devices. With connecting the Inverter to the battery, you can 'plug' in your appliances to the Inverter, giving you portable power wherever you need it.
Battery Power Inverters come in two different forms of power:
Modified Sine Wave: The output of a modified sine wave inverter is similar to a square wave output except that the output goes to zero volts for a time before switching positive or negative.
Pure Sine Wave: A pure sine wave inverter produces a nearly perfect sine wave output (less than 3% total harmonic distortion) that is essentially the same as (if not better than) utility-supplied grid power.
