What is a Car Power Inverter? How do They Work?

They are devices that convert direct current input, DC, from the car battery to alternating current output, AC.

Your car battery works on DC while small electronic gadgets and appliances need AC power while you charge their batteries, and other appliances need AC to run.

Direct current usually comes from a battery and has a low voltage of 12 or 24 volts, so when you install a power inverter, it does two things. First, it boosts the voltage coming from the battery to a higher number, then converts it from DC to AC.

The outlets from the inverter supply enough AC power to run chargers for a number of devices and appliances.

Inverters are not to be confused with power converters.

A Converter does the opposite to an inverter and is used for stepping down the AC voltage from your mains supply and converting it to a smaller, DC voltage. That’s not what you are looking for.

There are several ways to connect an inverter to the car battery. Smaller inverters can go through the cigarette lighter socket. Larger ones will connect directly using cables, or hardwired, into the battery. The last option is best suited for powerful inverters.

Electrical Terminology Simplified

All this electrical terminology might get a little confusing, so allow me to simplify them for you.

  • V – Voltage
  • I – Current
  • P – Watts
  • P=V x I

Voltage is measured in volts (V), current is measured in amps (I), and power is measured in watts (P). You see, electrical power is always equal to the voltage multiplied by the current, like in the formula above.

Appliances and devices need the same voltage of 12V or 24V from a battery, but the watts, or power, needed varies from each device, depending on the current it draws.

All devices should be marked clearly with all of their power, voltage and current ratings. It’s important you know the ratings of the appliances you want to run, before buying your inverter.

Types of Car Power Inverters

When DC is converted to AC, the alternating current creates a sine wave. The ideal sine wave is smooth.

Some devices are sensitive or have motors, and need this smooth, noiseless, consistently stable wave to work efficiently.

Modified Sine Wave Inverters and How They Work

Modified sine wave inverters use a simpler process to produce the sine wave. It’s not as prevalent with today’s technology, but efficiency can sometimes be reduced significantly with cheaper ones as their sine waveform can be more square than smooth.

Using modified sine wave inverters to power sensitive equipment, such as laptops, might have damaging effects over time. They should not be used with devices that use AC motors, and some devices controlled by microprocessors could also overheat.

Pure Sine Wave Inverters and How They Work

Pure, or true, sine wave inverters produce the same quality of conversion as generators or power grids. These inverters are a little more expensive, but they are designed to generate clean sine waves. Let’s look at the benefits of pure sine wave inverters.

  • Appliances running on pure sine wave can generate less noise
  • Sensitive devices and gadgets like smartphones could last longer
  • There are minimal chances of unexpected shutdown or errors
  • Motors run without overheating

Which of the Two Should You Purchase?

The answer to this question highly depends on you and why you need a car power inverter. If you need to run a variety of expensive electronics or devices with motors, a pure sine wave inverter is the better choice.

What are the Benefits of Owning a Power Inverter?

If you have a car, boat, RV or any other type of vehicle and you enjoy the comforts of home while traveling, then you need an inverter. Here are some of the benefits of owning one.

Charging Devices

Portable electronic devices, such as laptops, tablets, and smartphones, run out of power constantly. It helps to have multiple charging points in your vehicle.

Charging smartphones requires just the smaller inverters, but if you need to run a charger for a laptop as well, you will need a larger unit.

Recreational Purposes

If you continuously go on road trips, sports tailgating or camping, a power inverter comes in handy. You can make coffee with your espresso machine and keep your food fresh and your beer cold with a small car fridge or freezer.

If you went on vacation to a log cabin with no power, you can attach a long cable to the inverter and use that to illuminate the cabin. People who live on the road in RVs can really benefit from inverters as well.

With a pure sine wave inverter, you can drive anything from a microwave to space heaters, blenders, or even a washing machine.


While working in areas without electrical power, you can use your car as a source. With the car battery and an inverter, you can run a wide array of gadgets and tools.

Videographers or photographers often venture off to capture stories and images in new places. They always need to charge multiple batteries for their gadgets.

Handymen could also need to use power tools. For instance, while cutting trees, they can use a high power inverter to run an electric saw. They could run portable air pumps, welders, and other pieces of equipment that need a 110 volt AC supply.


Most older cars don’t come equipped with entertainment multimedia devices, such as DVD players. But this doesn’t mean your kids have to miss out on the joys of having them when you’re on the road.

A car power inverter can run DVD or CD players, games systems, and laptops.

What Risks or Drawbacks Should You Be Wary of?

Power inverters today are made safer than ever. They come with various features to keep users out of trouble. These features include cooling fans, automatic shutdowns, and overload indicators.

You need to check your appliance ratings to reduce the dangers. One of the risks you need to be wary of is using appliances that suck more power than your inverter can supply. You need to calculate the maximum you will need, depending on the devices and how many you plan to run at the same time.

Draining your car battery, or even over-discharging it, is a bad idea. One time might not leave it damaged, but several times definitely will. A car battery of 12V should not be discharged below 10.5V. If you’re going to be using your inverter for long periods, leave your car motor idling to keep the battery charged. Or at least have it running for 10 minutes every hour to keep it from draining.

If you plan to use your cigarette lighter socket, you need to check the rating of its fuse to get the number of maximum watts you can use.

For instance, if you have a 20-amp fuse, multiply that by the voltage of your battery, which is 12. Theoretically, you’ll get 240 watts to use. Any more than that and you’ll either blow a fuse or damage your devices. Cars have different size fuses, but the lowest is 10 amps.

To be on the same page, this wattage is the maximum your battery can supply from the cigarette lighter socket, not the inverter. Even if you have a 400-watt inverter, you cannot draw that much power with that cigarette lighter fuse.

Do Some Math

Using the example above, if you need to use more than 240 watts, you need to connect the inverter directly to the battery via cables. To be safe, check the power usage of your devices (usually located at the back or on the cable).

Let’s suppose your laptop’s going to use 50 watts, smartphones and tablets are five watts, and a DVD is 12 watts. That’s well below 100 watts, which is safe to use on the cigarette socket.

On the other hand, you might be planning to use high power appliances, such as microwaves, electric kettles, or toasters. They could pull in thousands of watts (kW). You then need to have a high wattage inverter and connect it directly to the battery.

Safety Tips

  • Keep your inverter away from the engine compartment or direct sunlight, and ensure it’s in a cool, dry place. This will prevent overheating.
  • Use safety-approved connection cables that are dry and undamaged. Ensure they run through a dry area where they can’t be crushed or pinched.
  • When the overload indicator goes off, remove whatever appliance was overloading before restarting it. If it shut off from overheating, wait until it cools down before trying again.
  • Wear protective gear when handling your battery.
  • Avoid metallic tools anywhere near your electrical sources.
  • Never go over your recommended wattage.
  • Don’t run the inverter longer than one hour when the car is off, because that will drain the battery (some inverters drain power even when nothing is plugged in).

What to Look for in the Best Car Power Inverter

There are several things you need to look for to get the right inverter for you. Depending on everything discussed so far, you need to not mess up by getting anything wrong. So, where do you begin?

The Power Rating

Car power inverters are rated in watts. The minimum you will find is 50 watts, with the maximum being 50,000 watts. Most car users don’t need anything more than 2000 watts.

To give you an idea, 300 watts is enough to run a TV, and twice that can drive small power tools. Two thousand watts (2kW) is more than enough to run hair dryers and average power tools.

More than that will usually only be useful if you run multiple large appliances at the same time. However, ensure it has more power than you anticipate using, in case your needs change.

Inverters also have a continuous rating and surge rating, which you need to consider as well.

They can handle an overload (the surge) for a few seconds. The surge happens when you plug in devices that need to power up, but once powered, they then start pulling charge at a normal continuous rate.

Low surge inverters, ranging between 25 and 50 percent overload, are the most common, and they cover most high-speed electronics. High surge inverters could go as high as 300 percent overload.

Choose the wattage and surge rating depending on what you need to run.

Number of Outlets

Single outlet inverters are plug-and-play kind of devices and run at a capacity of 150 to 200 watts. These are small, inexpensive, and fit the cigarette lighter. As outlets on them increase, the current capacity increases and therefore, so does the power requirement.

The number of outlets highly depends on personal preference and what you’ll be running at the same time. However, it does help to have a USB port and an AC power outlet.

Usb Ports

USB ports allow you to charge devices like smartphones, tablets and other similar gadgets that use USB cables. However, there’s not much difference between using a USB port and a standard outlet.

How it Hooks up to Your Vehicle

Can it use the cigarette lighter or do you need a direct connection? This will depend on what you intend using it to run.

If the inverter has a lighter socket plug, check what the maximum power output of your cigarette lighter connection is. Ensure that the device’s rating is below that.

Larger devices won’t come with a lighter socket option so they will have to be connected directly to the battery.

Cable Length and Materials

Consider where you’d like to place the inverter, then see to it that you have the right cable length.

It needs to be long enough to get to the battery from the installation point. They also need to be of thick, durable materials, and large gauge conductors to transfer electricity without heating up.

Safety Features

Power inverters these days come with an array of safety features to help protect your devices from damage.

  • Automatic shutdown – Shuts down the inverter to prevent the battery from draining
  • In-built surge protection – To safeguard electronics from power fluctuations
  • Soft start tech – Protects against power fluctuations, short circuits or extreme temperatures
  • Cooling fans – To keep the inverter from overheating


These devices are quite inexpensive, especially if you decide to get a modular sine wave. Still, it doesn’t make them disposable.

Look for a decent warranty that offers comprehensive coverage. You’ll have peace of mind when buying something that comes with a good warranty.

Remote Control

Some inverters come with remote controllers. These make it very convenient to control devices located away from the dashboard.


Price should not be a determining factor, but it’s a factor nonetheless. These devices are pretty affordable, but you get what you pay for.

Higher priced models might be more efficient, but get something that’s reasonably priced depending on what it offers.

Generally, the more power and safety you want, the more bucks you pay.

When it comes to inverters, only you can know how much power you need and then be able to choose the appropriate inverter.

We included some of the best car power inverters on the market in our guide at different ratings, so you can choose the one that appeals most to you.

Still, our favorite is the Bestek 400 watt power inverter. With two AC outlets and four USB ports, we feel it covers all the bases for most users. It’s well constructed and can drive a wide range of appliances.

The fact that you can plug it into the lighter socket or connect it directly to the battery makes it a great choice, and the cooling fan ensures it’s safety.

From childhood go karting and motocross, to collecting and obsessing over scalextric, matchbox and radio controlled cars, I've always had an obsession with cars. Learning through manuals, books, trial and error, and more knowledgeable family members, I've also enjoyed tinkering with the mechanics and electronics of any vehicles I've owned. Now, over 3 decades later, I've started this site as a place for me to share my knowledge, to teach others how to care for and maintain their vehicles themselves, at home, so they can get the most of their vehicles and save a pretty penny compared to always seeking out professional help.
