An inverter is a device that turns the power from a 12 volt dc battery like the one in your car or truck into the 120 volt ac power that runs all of the electronics in your house.
Some inverters have additional features such as a lighter plug so you can use a dc device along with the ac receptacle.

I want to be able to power my laptop inspiron 600m in the car and i have read some suggestions both in this forum and elswhere that say that a power inverter is a better deal than an auto air adapter.
You can use one of these devices to power all sorts of devices in your car but it s important to figure out how big of an inverter you need first.
A laser printer generally requires a pure sine wave inverter capable of producing at least 3 times the continuous wattage rating of the printer.
If you use a 300 watt power inverter your battery is going to drain approximately twice as fast as it would if you were using a 150 watt power inverter.
For instance a laser printer rated at 500 watts requires an inverter rated at 1500 watts continuous or higher.
