Some modern cars come standard with at least one AC outlet in the back seat, but many do not. If you need to plug something in, you can always buy a power inverter for your vehicle for power on the go. They are similar to the surge protectors you use at home but are specifically designed for mobile use. Just plug them into your car’s auxiliary power unit, formally known as a cigarette lighter, then plug in whatever electronic gadget in need of power. Here are the best power inverters for cars that are currently for sale on Amazon.

How to use a power inverter
Plugging in a power inverter is very simple. Just connect the plug of your inverter to your vehicle’s auxiliary power outlet, and then it will be ready to use.
Inverter vs converter
The names are similar but there are some key differences you need to know about. According to Renogy, “While inverter and converter can both transform voltage, they actually perform an opposite action to each other. A converter can turn AC power into DC. It can change the voltage level from one level to another, such as from 110v to 12v. On the other hand, an inverter transforms DC power into AC power.”
