Best 12V Air Compressors of 2021

Viair air compressors feature a lot in this review, for one simple reason; they are excellent products and hugely popular. This 400P model has a maximum working pressure of 150 PSI, and it creates a CFM of 2.3 at zero PSI.

It inflates all sizes of tires up to 35 inches, so it is ideal for maintaining ATV and farm vehicles. It has a duty cycle of 33 percent at 100 PSI, meaning you can run it for just over 3 minutes out of every 10 between rests.

It comes with a carry bag, a 25 ft extension cable, and an 8 ft power cord. It even has an anti-vibration sand tray.

So, we come to the second Viair 12V air compressor. This one is an onboard air system because it is designed to be mounted in your vehicle. It has a maximum PSI of 150 and a duty cycle of 33 percent.

The peak airflow is 2.54 CFM, and it has a 2.5-gallon air tank. It means you can fill the tank and store the compressed air until you need it. It is even powerful enough to run some small pneumatic tools.

This kit comes with a selection of tips, a 35 ft hose, and everything you need to mount it.

This Viair is less powerful compared to other models. It’s lighter, smaller, and easier to handle. It has a maximum working pressure of 120 PSI and generates a CFM of 1.47 at zero PSI. The weaker motor restricts the types of tires you can inflate, so this model will only handle tires to a maximum size of 33 inches.

Like the other models featured, this one has alligator clamps that attach directly onto the battery, and it has an LED/power indicator and a 10 ft power cord, plus a 16 ft hose and a 3-tip inflation set.

It costs a lot less than the other Viair air compressors, so if you want to save a few bucks, this is the model to get.

If you want a tire inflator that’s small and stores away in the trunk easily, this could be the best candidate. It only measures 8.9 x 7 x 3.4 inches and weighs just 2.35 pounds.

It can inflate car tires, bike tires, and some small sports equipment. It does have limitations because it won’t work with swimming pools and inflatable kayaks. It has a maximum PSI of 80, 3 light modes, an LCD, and auto shut-off when the correct pressure gets reached.

It’s also cheap when you compare it to the lowest priced Viair model. This compressor is half the price!

When it comes to inflating tires, this 12V air compressor is pretty hard to beat. It plugs directly into your car’s cigarette lighter, and because it is compact and lightweight, it is a breeze storing away in the trunk of your vehicle.

This model has a maximum of 120 PSI, a preset pressure feature, and an LCD for easy nighttime readings. It also has 5 light modes, including a flashing light and a power-saving setting.

The hose is 3.7 ft long, and the power cord measures 9.8 ft. It can handle small car tires as well as SUVs and sedans, so it is the perfect travel companion.

This 12V air compressor is seriously impressive. It has an airflow of 70 liters per minute, which is double that of the energizer model. It means that this compressor will inflate truck, SUV, ATV, and car tires in no time at all.

It has a maximum air pressure of 150 PSI, and it has a double cylinder direct drive pump, which delivers an efficient service to make the compressor quiet and reliable. It comes with all the kit you need to keep you moving in an emergency.

And thanks to the large carry handle, it is portable and easy to stow away. Like other similar models, this heavy-duty compressor clamps directly to the car’s battery, and it has an 11.5 ft coil hose and an 11.5 ft power cord.

If you’ve ever dreamt about driving through the streets of your town sounding like the Dukes of Hazzard, now’s your chance. This GAMPRO compressor and air horn will blast out 150 decibels of sound. That’s enough to wake up the entire block.

The air compressor has an aluminum turbine cavity and a chrome-plated metal case. It is lightweight, compact, and delivers when it’s needed. It connects to any 12V vehicle, from a car to a boat, and is the ideal tool when you need to get noticed.

This is the final Viair product to appear, and like the Viair heavy-duty model, this one has a 2.5-gallon tank. The compressor and tank are designed to fit your vehicle, giving you a mobile pneumatic station that can power small air tools and inflate tires.

This compressor has a maximum working pressure of 150 PSI and a duty cycle of 33 percent at 100 PSI. It also generates a CFM of 1.77 at zero PSI. Because it is mounted to your vehicle, it can withstand ambient temperatures ranging from -40 degrees Fahrenheit to 158 degrees Fahrenheit.

The tank is ideal for storing compressed air for when you need it, and it has a drain valve for siphoning away any excess moisture.

Budget 12V air compressors are more important than you might think. They give people the ability to own a compressor even if they have limited funds. This Breezz model is a prime example of a cheap 12V air compressor.

It’s compact, lightweight and it does what it says on the tin. With 150 maximum PSI and the ability to fully inflate a 195/65R15 car tire in just 4 minutes, you can see why this is a valuable tool to keep in the trunk of the car.

It has an LED light, an LCD readout, a pressure adjusting switch, and a 10 ft long power cord. For the price, this is pretty hard to beat.

If you want an air compressor with a little more power, consider this TIREWELL model. It produces 150 PSI and a CFM of 2.12 at zero PSI. When you have larger tires, airflow is crucial to speeding up the process.

It also benefits from a direct drive double cylinder pump, which is responsible for delivering fast and efficient service to the compressor. It also means this compressor is quiet and as vibration-free as possible.

It works particularly well with RVs and trucks, but it is equally at home inflating kayaks, sedan tires, and other equipment.
