Car inverter is an electronic device that takes a DC input and converts it into an AC output. Since car batteries provide DC voltage, and most consumer electronics work on AC, inverters are useful for using laptops and other devices on the road. However, there are some vital constraints to keep in mind whenever you use an inverter in your car. Factors like the capacity of the car battery, rated output of the alternator, and output wattage of the inverter can all play a part in determining which devices can be plugged in and used.
Power inverters for car can work in just about any vehicle by using the outlet that has been traditionally used as a cigarette lighter. Just plug the inverter into the 12v socket and you'll have a safe and stable power source for your electronics. The chart below offers a look at the highest rated inverters in this category so you can quickly compare and contrast each make and model.
