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 8.43 x 6.61 x 4.17 inches and weighs just 2.2 pounds.

It can inflate car tires, bike tires, and some small sports equipment. Moreover, it can also be used to inflate cushions, pillows, and mattresses. It has a maximum PSI of 100, LED lights, 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 less than half the price!

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