Purpose of Power Inverter for Car

The main purpose of an inverter for the car is to convert the current from DC to AC. Most electronic devices or appliances we use in our households run with AC current. Therefore, the power outlets we have in our homes are AC power outlets.

However, a car produces current with an alternator and stores it in a battery. The battery provides DC to all the other devices. This means, we cannot directly connect our devices to the car; we need a converter. This DC to AC converter for a car is called an inverter.

Without an inverter, we could not have the flexibility to use our essential electronics using a car battery or in the car. It allows us to have access to electronic devices on the go.

Buying Guide for Car Power Inverter

Firstly, ask yourself why do you need a car power inverter. That will give the answer to what type of inverter you need. However, there are some criteria you need to check before making your purchase for a car inverter.

Types of Inverter

There are usually two types of an inverter. One type is for cars, and the other one is for home uses. Car inverters usually have AC power outlets and USB ports. They get power from the battery and covert it for use. Generally, car inverters have power up to 1500 watt. Some come with more capacity, like 2000 watt.

On the other hand, home inverters get energy from solar panels or power banks and provide power to the home appliances. Home inverters come with a capacity of 3000 watts. Any type of appliances can be used with this watt.


Power of an inverter is indicated with watt. The higher the watt, the more powerful electronics can be used with it. Phones, laptops, tablets do not require many watts, and you can use a 150-watt inverter for it.

However, if you want to use your inverter for TV, refrigerator, coffee maker, air mattress, etc., then you might need more wattage, like 2000W. It totally depends on you how much your need is.


You must decide how you are going to use your inverter. If your purpose of using an inverter is only to run the entertainment system, then you might not need much wattage. Laptops, phones, tablets, etc., does not take many watts to operate.

On the contrary, if you are going camping and want to use your car battery for running appliances like coffee maker, cooker, etc., then you will need higher wattage inverter.


Having power is not enough if you do not have many outlets to plug in your devices. However, it depends on you how many AC outlets you need. If you want to connect more devices, you should choose one that comes with multiple power outlets.

For standard inverters, they come with three-prong AC power outlets and USB ports. You can get inverters with only one power outlet to upto four AC power outlets.

Sine Waves

We get the option between a pure sine wave and modified sine wave. Some devices need pure sine wave power to function properly and vice versa. Irregular waveforms can damage your devices.

Therefore, most inverters use either a pure sine wave or modified sine wave. A modified sine wave is better for devices as they put less stress on the devices, and pure sine wave increases efficiency.


Most inverters can be connected to your vehicle with the cigarette lighter plug. It is the simplest way to connect an inverter. However, some inverters come with clips to directly connect with the car battery.

If you plan to use your inverter on camping or outdoors, you can have one with clips. That way you can use your inverter directly with the battery.


Some inverters are so compactthat you can use them only from the front seat. Some have longer cables to provide more accessibility. If you are more prone to charge your devices from the backseat, you need an inverter with longer cables. Also, if you own a bigger vehicle or RVs, then you might want an inverter with longer cables.

Build Quality

The body of the inverter needs to be sturdy. Otherwise, it can break easily. The inverter body also has to have the capability to secure the inside circuits so that they do not get damaged.

Cooling Fan

Not all inverters come with a cooling fan. It is best to choose one that has a built-in fan. Electronic devices can heat up a lot, at a time like that a cooling fan comes very handy. Cooling fan prevents overheating and damaging devices. The cooling fan increases the lifespan of your inverter as well as making it safer.

Safety Feature

Safety features are important for an inverter; otherwise, your devices can get damaged. Most inverters come with a minimum one fuse so that burst of electricity does not damage the device that is connected to the inverter. Some good ones come with multiple fuses and also have backup fuses. Make sure your inverter has a fuse before purchasing.

Some other safety features like indicators are also necessary. Some basic inverters have only LED to indicate the condition of the inverter, whereas, some inverters have LED to display the input, output wattage, overheating, etc. issues.

Remote Control

There are some inverters in the market that have remote access control. This feature might not always be necessary, yet it might come in handy. In small cars, you might not need remote access. However, this feature will be very beneficial if you want an inverter for RV.

Other features

You can get some basic inverters that get the job done, as well as inverters with some special features. You can get the option for on/off switch. Some have an only light indicator for warning whereas some have LED for that. Some advanced inverters can be accessed using an app or have a remote switch. If you are into these type of additional features, you can choose one with those.


Whenever you think about making any purchase, the first thing comes in your mind is the price. However, for car inverters, it does not matter much. For higher wattage, the price can be a bit higher. Though, most of the inverters come at similar prices and are affordable. According to your need, you can choose one.


Warranty can be helpful when something goes wrong with your inverter. Good inverters might not have issues; still, it is best to have a warranty in case you need it. You do not have to go through the hassle of buying a new one if you have a warranty. You can use a free servicing and replacement for your broken inverter.

How to Install a Power Inverter in a Car

Inverter for cars or other vehicles is very easy to use or install. All you need to do is plug it in. Most inverters come with cigarette lighter plug. However, in this way you cannot use the full wattage.

The other way is to connect with the battery directly. This is a bit difficult way to connect the inverter. You will need cable to connect with the battery and you must know the way to install a power inverter in a car. You will get the full wattage if you connect the inverter directly with the battery.

Different Uses of Inverter

Ideally, an inverter for a car is used to charge devices that we use everyday, like smartphones, tablets, laptops, etc. However, an inverter can be used for various reasons. There are so many people whose need from an inverter is not charging phones but other things.

If you go camping, you can use the car battery with the help of an inverter to do a lot of tasks. It can be used to inflate air mattresses, TV, coffee makers, electric cooker or stove, etc.


If your car has become your second home, you cannot live without a car inverter. Having so many electric devices around us, we always need current to operate them. We are living at a time where we cannot operate without electronics. An inverter is a must  to charge or make these electronics or appliances work on the go.
