The Guide to Power Inverters for Cars

Want to charge your laptop, play a portable stereo or watch TV in your car? You should invest in a car power inverter. A power inverter allows you to have an AC outlet in your car that you can use anywhere you want. These inverters come in handy, especially when you are tailgating, camping, or on a long road trip. These simple devices can be charged much faster compared to a car battery charger and are incredibly convenient to hook up and use.

The best thing about them is that they aren’t much expensive and you can easily afford one for your car. In short, when this thing is installed in your car and switched on, you can run pretty much all sorts of home electronics in your car.

In this article, we will provide you helpful information about these amazing devices for your car. Once you are well informed about them, you will know exactly how to go about shopping for the best power inverter for your car. Let’s get started.

How Do Car Power Inverters Work?

If you are a bit of a technical person, you will know the fact that DC power doesn’t generate a high voltage that can run electric appliances. This is where a car power inverter comes into action – it goes through two processes as the DC energy runs through it.

First, it boosts the voltage of the incoming electricity to make it to the range that is better suited for running AC devices. Once the voltage of DC input is increased, it is then converted into the same AC power that your home runs on.

After these two steps are completed, a power inverter can then supply AC voltage to any electronic device you want.

Benefits of Owning Car Power Inverters

  • You can easily run a TV, electric kettle, portable stereo system, or other electronic appliances in your vehicle.
  • When you are going on tailgating or camping, you can bring along your laptop, computer, or portable fan and never worry about charging them.
  • It provides a decent emergency power backup option to run important electronic devices after a storm or other unfortunate event that causes power loss.
  • A perfect choice for road truck drivers to install in their rigs.
  • An ideal option to equip your boat with an AC power outlet to run all sorts of home electronics.
  • Types of Car Power Inverters

Types of Car Power Inverters

1. Modified Sine Wave Inverters

This type of power inverters uses a relatively simpler process to generate the sine wave. During this process, the efficiency can sometimes be reduced remarkably with cheaper models as their sine waveform is more of a square than smooth.

However, using modified sine wave power inverters to power sensitive devices, such as your laptop, might ruin its efficiency over time. These power inverters shouldn’t be used with devices that use AC motors or are controlled by microprocessors as they could overheat.

2. Pure Sine Wave Inverters

Also known as true sine wave inverters, they can generate the same quality of Alternating Current as power grids or generators. Although this type of power inverter is a little more expensive, it is designed to generate smooth sine waves that the former type cannot. Following are some benefits of pure or true sine wave power inverters for your car:

  • Electronic appliances that run on pure sine wave inverters produce a lot less noise.
  • Sensitive devices such as smartphones and laptops are safe from overheating or other damages that might occur.
  • Minimal chances of sudden shutdown or errors.
  • AC motors of appliances run without overheating.


Want to know which one to get for your car? Well, the answer depends on your requirements and why you need a car power inverter in the first place. If you want to run a variety of electronic devices or expensive gadgets with motors, you should definitely invest in a pure sine wave inverter.

Things to Consider When Buying a Car Power Inverter

  • Budget

Price shouldn’t be a huge factor in the decision when buying a power inverter because most of them are pretty affordably priced. However, you will get what you pay for. This means getting a power inverter made by a renowned brand is much better than buying a cheaper one that might damage your electronic devices.

  • Power Output

Not all the power inverters are designed the same way when it comes to supplying power. You should make sure that the power inverter you are buying meets all your demands for portable AC electricity. This means if you are planning to run your TV, laptop, and electric fan all at the same time, you should invest in a power inverter that can supply enough power output.

The rule of thumb here is adding up the total wattage of the electronics that you want to run off your car’s power inverter. The estimate wattage will help you decide which power inverter to buy.

  • Number of Outlets

Not only should you consider the output of your car’s power inverter but also the number of outlets it has. Most of them only come with one or two outlets.

  • Build Quality

You don’t want to invest in a power inverter that is made of flimsy and cheap materials that would give up sooner rather than later. Always remember that they will be working in a pretty harsh environment, and they might get very hot while they are converting DC voltages into AC. You need a power inverter that is made of solid materials and have a robust build quality.

  • Safety Features/Device Protection

To make sure you don’t get your devices damaged, you should look for safety features and built-in protections in a power inverter for car. It should be equipped with things such as fuses, low battery shutoffs, and overheating protection. Plus, it should have overload and overcurrent protection.

  • Warranty

Last but not least, the warranty should not be taken for granted. Although these are affordable devices, they aren’t disposable, and you won’t be buying them frequently. So, make sure the power inverter you like also comes with a decent warranty.
