Today cars are no longer just a means of transportation as each power inverter manufacturer stuffs its product with a bunch of incredibly useful features that many motorists love. If you are planning to use the car in a wider range, I suggest you consider the best power inverter for the car. It is a device that is capable of converting your vehicle’s DC electrical power (12V / 24V) to AC voltage, which can be used to power or charge a great range of household appliances and accessories.
Such a device has a number of significant advantages. If you have it in your car, you can easily use a wide range of different devices that have become an integral part of the car. These devices include TV, DVD, and Blu-ray players, all sorts of game systems, Catalytic heaters, Power tools, and many others. In my review, I will help you to find a decent 12V to 110V inverter, choose the most appropriate model for your vehicle, and explain all the details you need to know about these appliances.
Best power inverter for a car
Wattage – one of the most important things
Among the best power inverters for cars, there are many different models on the market. Initially, you need to decide on the power that will be required from it. In fact, there are both 100W and 4000 – 5000W. In addition, when choosing, it is always necessary to understand the approximate model of using the device.
If you decide to purchase such a system, when connecting the inverter, you should take into account the power of the connected device. For example, if you connect a phone or laptop, you shouldn’t start the car and use the battery power. We all know perfectly well what troubles and unforeseen situations happen when the battery is discharged at the most inopportune moment. Therefore, if the power of the connected device is more than 500W, then it is better to start the vehicle so as not to discharge the battery. Now, I propose to briefly review the list of devices in relation to the amount of energy they consume.
- Laptop – about 50W
- Mobile Phone Chargers – approximately 2 – 6W when charging
- Microwave – 1200W
- Electric kettle – approximately 1000 – 1200W
- Light Bulb – 100W
In addition, before buying, you should definitely find out the power of the car generator. To avoid complete discharge of the battery, the power of the inverter must not exceed the power of the machine’s generator. Also, keep in mind that not all of the generator’s power will go to the inverter when the engine is running. As a rule, about 50% of it will be spent on the needs of other vehicle systems. Here is a short example of car models and their generator power.
- 2019 Ford F-150, 3.5L – 4900W
- 2017 Toyota Camry, 2.5L – 3000W
- 2018 Ford Focus, 2.0L – 2700W
And finally the most important thing. When choosing an inverter, you should always pay attention to its power surpassing the devices that will be connected to it at the same time. If you connect more powerful equipment to a low-power inverter, there is a huge chance that it will simply fail due to operation at maximum loads.
In this way, we come to the most important rule. The power of the inverter must be twice as large as the total power of all simultaneously connected devices that consume energy.
Ways to connect the car power inverters
Cigarette lighter
Inverters that are connected to a car cigarette lighter are primarily suitable for operating a laptop, charging a phone, and the like. For such tasks, it is easiest to choose inverter models with a power of no more than 100 W. The fact is that it is the cigarette lighter that gives out no more than 100 W, to which the inverter is connected.
Direct connection to the battery
If your choice falls on more powerful inventory for more resource-intensive tasks, it is important to remember that they connect directly to the car battery since they are more powerful and can deliver more than 1000W. Often, they are used for outdoor recreation and connecting tools, TVs, household appliances, and other similar consumers who need a more powerful inverter.
Pure sine wave inverter vs modified
Some inverter models produce a modified sine wave. In fact, it is great for instruments that are not sensitive to waveform at all. First of all, these are heating devices, incandescent lamps, devices that have switching power supplies, such as computers, laptops, digital TVs.
During the operation of a modified sine wave inverter, more noise enters the power grid, so medical equipment and communication systems may be unstable. An unfavorable phenomenon appears that affects transformers and electric motors: the device starts to warm up, and the efficiency decreases.
On the other hand, there are some devices that are susceptible to various kinds of interference, for example, compressors, electric motors, pumps, etc. The point is that they only work with a pure sine wave, which is generally more stable than a modified sine wave.
Generally, these inverters are usually more expensive but can work with just about any electrical device or appliance.
In the event that a car serves as a home for a traveler. For instance, there are travelers who travel for weeks or months and usually have to rely on their inverters to potentially charge laptops, phones, portable speakers, and more. In such a case, I highly recommend devices with the pure sinusoidal current.
In another situation, if you do not travel for a long time and do not need to connect demanding electronics to an inverter and charge your gadgets at home 90% of the time, you can just save money and not waste it on a car inverter with a clean sine wave, but simply select a modified sine wave converter.

Buyers Guide
Continuous vs peak car power inverter outputs
There is always one factor to consider when choosing the right inverter for your vehicle. It is important to know the concept of peak power. This is the power that the inverter can supply for short periods of time during demand surges. On the other hand, there are concepts of continuous power, which is the limit for normal operation. If the devices you choose to draw up to a total of 600 watts, you will need to buy an inverter with a constant output of 600 watts. An inverter rated for 600 peaks and 300 continuous values will simply not help you, and you will just waste your money.
What size car inverter do I need?
If you are unsure of the exact power requirements of your devices, you can figure it out using simple math. Let’s take a look at specific examples. The key formula for this is: Amps x Volts = Watts.
It’s very simple: you need to multiply the input amps and volts of each device to determine its consumption in watts. But if you go the easy way, this information can often be found on the Internet. In other cases, it is better to look at the power source.
As I said, for example, your kids want to use the Playstation in the car. In such a situation, you need to study the power sources. This is necessary because Sony has released a number of models with different power requirements over several years.
If we plug in the numbers, it looks pretty simple. First, you need to look at the power source for a specific device model. For example, its input voltage is indicated as “100-127 V” and the current is “~ 5 A”. If we just plug these numbers into our formula, we get: 5 x 120 = 600. The number 600 means that you need a 600W inverter to use the console in the car.
Can a modified sine wave inverter damage electronics?
Many people probably don’t mind using an inexpensively modified sine wave inverter in your camper. However, there are a few different things that you don’t want to run off a modified sine wave.
For example, any device that uses an AC motor isn’t going to work to full capacity on a modified sine wave. Appliances such as refrigerators, microwaves, and compressors that use AC motors fall into this category. They just won’t run as efficiently on a modified sine wave as they would on a pure sine wave.
When choosing, it is important to remember that running an AC motor on a modified sine wave may lead to a buildup of excess waste heat that could damage the equipment. In fact, you can still do this, but at your own risk.
A modified sine wave can also interfere with the technique. For example, if you are charging the radio and trying to listen to it, there are often situations where interference is heard. This is precisely due to the use of the modified sine wave.
It is important to remember to be careful when working with medical equipment. For example, a pure sine wave inverter will perform much better if you use a CPAP to help correct apneas when you’re asleep. Also, when dealing with CPAP, their manufacturers often warn that you can damage your machine with a modified sine wave inverter.
Many, perhaps most, medical equipment, such as oxygen concentrators, also need a pure sine wave. When working with this equipment, you’re better off using pure sine wave power or looking for a unit that can be powered by DC without the need for an inverter at all if it’s available.
How to install a power inverter in a car?
Before installing a car power inverter directly, there are three key points you have to know.
First, you need to be aware of the portable device power requirements. The fact is that the inverter needs to be able to supply enough power for all of the devices that you want to plug in at once.
Secondly, it is very important to be aware of the inverter installation locations. Most inverters can be installed anywhere. The point is different, and you first need to think about accessibility for plugging devices, how you are going to connect it to power and ground, and whether it will be able to safely dissipate the heat that it generates during use.
The third and final point is understanding the power inverter wiring issues. Small inverters usually run on a cigarette lighter, and it’s easy to understand. But when we talk about larger inverters, they have to be wired directly to the battery with a large in-line fuse.
Where is the best place to install the inverter
The inverter is not a new thing, so users are already accustomed to using “normal” locations for their inverters, for example, In the trunk, underneath a seat, or Inside the glove compartment. More thoughtful people often mount it to the floorboards.
When you finally come to consider the locations for placing your inverter, be sure to decide on two things. First, think about where your power input is going to come from. Second, figure out how easy it will be to plug in your devices.
Another of the most important details, in this case, is the consideration of such an item as heat dissipation. Most inverters have built-in fans, and a lot of them are actually designed as big heat sinks. If your inverter has a fan, you’ll have to find an installation location where the airflow won’t be blocked. Otherwise, the airflow will be incredibly warm, which in the future may either overheat the device too much or start a fire.
Сan you use an inverter while driving?
One of the most common questions is whether a cigarette lighter or a direct connection to the battery inventory can be used while driving. In fact, yes, of course, you can.
In such a situation, the most important thing is to follow the rules described above. It is always important to remember that the power of the inverter must not exceed the power of the vehicle’s generator in order not to completely discharge the battery. The sudden discharge of the battery is accompanied by many unpleasant problems with which we would clearly not want to spoil the mood.
Can I use a car battery for the inverter?
Answering shortly – Yes, you can. However, this is not a good idea as it is not worth draining your car’s battery.
For example, a small inverter that works from a cigarette lighter just to charge a cell phone does not cause any problems. There is simply not enough space in the cell battery to displace 10% of the car battery charge.
But if we’re talking about larger inverters – you need to be more careful. A 2000W inverter can place a strain on the battery or damage it. For example, if the vehicle is going to be stationary for a while, on a campsite, for example. When the vehicle is still, the battery is not charging, obviously. In this instance, consider running the engine frequently to top up the battery charge level.
If you are considering long-term stops, consider bringing some car batteries with you to hook up to the inverter instead of the installed car battery.
Can you charge a battery while using an inverter?
In fact, it’s completely safe to keep your Inverter connected when charging your battery.
This is a very common practice, but unfortunately, the charger suffers from this. Nothing bad will happen to your inverter, as well as to the battery. As long as you have the inverter connected, the battery is never going to get fully charged. Thus, the charger is going to run at full tilt for as long as your inverter is running. Of course, doing this is undesirable since the sucker is going to run hot and one day will simply burn out.
Why is my power inverter beeping?
Usually, if a person complains about beeping an inverter, there are three reasons for this and the same three solutions, let’s take a closer look at them.
The most common reason for continuously beeping an inverter is that it is running or operating on battery power. The beeping lets the user know that the unit is transferred from online operation to battery operation. The solution to this problem is quite simple: in this situation, the battery power supplied outlets have now become battery powered.
Another reason for the beeping sound could be an alarm for a low battery. Basically, it’s obvious – your battery needs recharging. In addition, some inverters have an auto-shutdown function to prevent the battery from completely discharging. Typically, the alarm rings for 2 minutes before shutting down.
The third reason for this sound is capacity overload. If the device is in overload condition then you will hear the alarm and must remove the non-essential equipment. The alarm will keep ringing until you remove the extra load. If your inverter is not enough for you, consider options for a new one.
What happens when the car inverter overloads?
You can only connect devices to an inverter that does not exceed their rated power. If you still try to connect loads bigger than its rated power, it would get damaged without protection.
In any case, with built-in overload protection, the inverter won’t start or stop running without any damage. Situations also happen when after a few seconds, the inverter tries to start again automatically in the case of extra loads being removed. If for some reason, you haven’t done this, the inverter will definitely turn off again.
If you make a few more attempts, you will have to restart your device manually. It is also important to understand the fundamental difference between continuous and short time overload. In this situation, short-time overload means that overload condition is present. For example, kitchen appliances like a microwave oven often require a very big current when startup than their rated power. In such a situation, the inverter can take up to 200% overload for a short time.
