Portable tire inflators often get thrown under the bus for not being as powerful as their plug-in counterparts. However, years of R&D in battery and motor technology has led to big gains in power and portability. Aside from portability, the peace of mind that you gain from having readily available onboard air is simply invaluable. Whether you’re crawling through the Rubicon trail or cruising down the interstate, you never know when you’ll need a quick hit of air.

What to Consider

While there are plenty of metrics to look at when it comes to air compressors, the most important will be cubic feet per minute (cfm). The higher the number, the faster the compressor can add air. For typical road usage, any unit with around 1 cfm will do the trick. Most road tires have a very small air volume and can be inflated with relative ease. However, off-road enthusiasts with bigger tires will want to look for at least 2 cfm. Anything lower than that isn’t worth the investment, however modest.

The other important number to pay attention to is the maximum psi. While cfm refers to the amount of airflow being produced, psi is a measure of how fast that air can be supplied. The closest comparison would be putting your thumb on the nozzle of your garden hose. It’s still supplying the same volume of water, only at a much higher pressure.

If you’re a casual motorist, we recommend the more portable–and affordable–units on this list. There’s no reason to spend more than $75 for everyday needs. However, if you’re a weekend warrior in the overlanding scene, some of the more brawny units will be right up your street.

How We Selected

As a lifelong petrolhead and adventure seeker, I’ve developed a deep understanding of the importance of being prepared. In narrowing down my list, I looked at factors like cfm, max psi, portability, and price. Aside from my personal experience, I also consulted expert reviews from longstanding websites like Overlander, 4 Wheel Parts, and Mobile Air Systems, along with customer feedback on retail sites like Amazon.

Similar to the Viair 300P, this unit can be powered by a car battery. Despite its modest price tag, GSPSCN didn’t skimp on the construction.

Not everyone has the luxury to spend $300 on a portable tire inflator that can inflate a 37-inch tire in under a minute. That’s why the Viair 88P occupies a very important spot in the brand’s lineup of portable air compressors. Although this more modest unit can only muster 1.4 cfm, it still has enough muscle to air up a 33-inch tire using a direct battery connection. Despite several complaints about units being dead on arrival, a bigger brand like Viair should have top-notch customer service.

Despite Smittybilt’s history of outfitting Jeeps with go-anywhere gear, its 2781 compressor is built like a tank.

Not without reason though, as the Smittybilt features a 0.3-hp oilless direct-drive motor that can run continuously for 40 minutes before overheating. The unit also comes with a 24-foot air hose and can be permanently mounted to your vehicle if you so choose.
