Inverters turn DC power into AC power, the type of current that powers everyday appliances. A common use of an inverter is to connect one into a car's cigarette lighter and then plug small home appliances into the inverter.
Inverters have added features over the years, and today many inverters include emergency radios, lights, or their own internal battery to store power.
When you purchase an inverter, you need one that can handle the wattage of the appliances you intend to connect to it. Some inverters are made specifically to power low-wattage appliances, like portable phones or digital music players. Others can handle heavy-duty power tools.
If you're buying an inverter that's powered by its own battery, you'll have to consider how many hours the inverter can provide power before needing a recharge.
