Best Car Power Inverters Buying Guide

What is a Car Power Inverter?

You may be wondering what exactly is a car power inverter. Well, picture inside of your home – you will have a range of different power outlets designed to run things such as your household appliances and luxury items.

All of these different items need to get their power from somewhere, so they are plugged into your normal outlet in your home.

The devices that are powered by your home’s electricity will run off something that is known as an alternating current or AC for short. The current will move continuously in various directions throughout the electrical lines in your home.

Electricity doesn’t quite work the same way in your car as it does in your house. Instead, you have something called a direct current, or DC for short. This is created by the alternator in your car and the current is stored inside of the battery.

Unfortunately this sort of current doesn’t provide a very high voltage, which makes it difficult for you to run a lot of larger devices with it.

A power inverter is the answer to your prayers in this situation. The device will convert your DC electricity into AC electricity, much like you would find at home. You can then use the power to run all of your key items, such as your laptop, TVs and more.

Things to Consider

There are a lot of things that you should think about before buying your car power inverters.

After all, there are a lot of options to choose from, but not every one of them is going to work well for your particular circumstances.

So, if you are having trouble deciding which car power inverter is going to be the best choice for you, here are a few things to keep in mind as you make your decision.

Power and Wattage

The first thing you need to consider is what exactly you are planning on using the unit for.

For instance, is it going to be used to power up your refrigerator in your RV? Are you going to use it to entertain yourself, or to keep your cell phone connected to the rest of the human race while you are out on a camping trip?

Asking yourself these questions is very important for helping you to choose the right option for you. Certain kinds of power converters just aren’t going to be practical for running multiple large devices at a time, such as your laptop and your fridge.

Think about the number of devices you are going to use, then add up the total wattage of these devices. This will help to ensure you aren’t making a wild guess and underestimating the amount of power that you’ll need to get your devices up and running.

One of the main things to consider in a power inverter is the maximum watt power that the inverter has. Generally, the vast majority of power inverters are more powerful than what you actually need for your car, especially if you’re only charging your phone.

If you are looking to power up multiple devices at once, then you should think about a generator with about 2000W.

Amount of Charging Ports

Power inverters are getting more and more charging ports as time goes on.

Not every car power inverter provides a massive amount of power, however. There are some power inverters that only have around 2 or 3 outlets in total. Some of them might come with USB ports too.

It’s really handy to have a range of different ports, especially with the number of different gadgets in the world increasing as time goes on.

It’s also important to think about where the ports are positioned. Some users just can’t plug in all of their most important gadgets because the power ports aren’t positioned in logical places, so they are limited in the amount of ports they can use.

Most different power inverters come with two AC outputs as standard. Some even have cigarette lighter ports which will let you charge as many as 5 devices at one time, if you are so inclined!


As a whole, car power inverters are fairly well priced so you don’t need to worry about spending a fortune on a particular model.

With that being said, if you get a cheaper model, you are likely to get a less efficient product. The price of the product often reflects the power of the inverter, so this is something that you should keep in mind.

You should try to budget based on your particular desires and needs, rather than just buying the cheapest option on the market.

Ease of Set Up

You don’t want to be spending hours on setting up your car power inverters – you want it to be easy to do and take relatively little time!

For this reason it’s important to look for a model that is easy to set up. There are some products that will just plug into the cigarette lighter or your auxiliary point in your car, and these are certainly the models that are easiest to use.

On the other hand, if your inverter can supple larger amounts of wattage then it will have to be connected right into the battery of your car. You will need to make sure that the cable connections in the inverter can clamp or hook over the battery terminals in an easy way.

Build Quality

When you are buying your car power inverters, you need to check the body and the cables of the product.

Are they sturdy?

If the product is at all weak or flimsy then it simply isn’t going to last as long.

This is especially true if your inverter is in your car getting bashed about. You should think about getting a car that has a metal body, such as aluminum alloy.

Cooling Fans

Cooling fans are ideal as they help to minimize the amount of internal heat generated, and this helps to prevent the unit from overheating.

It doesn’t take a very long time for car power inverters to heat up, and if the inverter heats up too fast it may end up triggering the built in thermal overload, which is best avoided if possible!


As with any electrical product, you want to know that you’re covered in the event that something goes wrong down the line.

The kind of warranty will largely depend on the product, but usually warranties last for around 18 months. This is pretty decent, and is even better if you are using the inverter on a regular basis.

There are some warranties on the market that even last as long as 3 years. The longer the warranty is, the more peace of mind you get.

Safety Elements

Car power inverters have a pretty high power output, so you need to prioritize your safety above all.

You should be looking at least for fuses, low battery shut off features and overheating protection.

Remote Control

Some car power inverters can actually be controlled via a remote. This means they are much easier to use, and they are very convenient for when the inverter is set up on the car’s battery.

Not all power inverters come with automatic shutoff switches, so a remote control is handy as you can easily turn off the inverter’s power from some distance away.

Frequently Asked Questions

What ways can I connect the car power inverter to my vehicle?

There are two main ways that you can connect your power inverter to your vehicle – using your cigarette lighter or directly to the battery.

Connecting the inverter to the lighter is the easiest way to use the inverter, but this way won’t allow you to power things that have higher wattage.

It’s a little more difficult to connect the car power inverter to the battery, but it will allow you power things with higher wattage.

You should ideally be looking for a product that will allow you to use the inverter in both of these ways.
