Don't Get Deflated: Best Portable Air Compressors of 2024, Tested (2024)

Craftsman's six-gallon pancake air compressor (CMEC6150) is nearly identical to the DeWalt model we tested, with only a few exceptions (such as the pressure dial being located below a dual-gauge setup). Other similarities include dual attachment points, rubber feet for reducing movement and sound, and a convenient handle for moving the unit around.

It has a tested max psi of 172, slightly better than the stated 165 psi, and a decibel level of 89, a decibel louder than the DeWalt. Like the DeWalt, the unit is lightweight at 29 pounds, but it has a nearly one-minute-slower time to fill the tank of 3 minutes, 21 seconds.

Also much like the DeWalt model, this air compressor provides respectable performance and represents good value for its price, making it a suitable choice for medium-duty applications.

The DeWalt six-gallon pancake air compressor (DWFP55126) is an efficient choice for anyone who wants a balance between performance and portability. With a six-gallon tank, it boasted a max psi of 147—slightly lower than the stated 150 psi. The unit is relatively lightweight at 29 pounds, with a decibel level of 88 during operation.

It took approximately 2 minutes, 32 seconds to fully fill the tank, which is pretty impressive for its size. The handle on the top also made for easy transport, despite the lack of wheels. Overall, it's a solid option that balances features and compromises well. DeWalt also makes a battery-powered 2.5-gallon model nearly identical to this compressor but with a smaller tank—and a higher price.

Harbor Freight's McGraw hot-dog air compressor is ideal for those on a tight budget who still want the convenience of pneumatic power around the garage.

With a small three-gallon tank, this compressor is highly portable at only 15 pounds. However, despite being the lightest of the bunch, it's also the loudest on the list with a decibel level of 99. This could likely be reduced a bit by adding some quality rubber feet to the bottom of the compressor or setting it on a padded garage mat.

The tested max psi was 105—5 psi below the stated number. While this should be more than enough for filling up tires and less demanding pneumatic tools, it's worth noting this item will likely struggle with more powerful impact wrenches and more demanding tasks. It also took roughly four minutes to compress entirely, which is a bit slow considering this is one of the smaller tanks we tested.

Overall, given its smaller tank size and higher noise level, this compressor is best for small, intermittent tasks. But if you don't mind those trade-offs, it's hard to argue with its comparatively low price. If you want a little more capacity, Harbor Freight also has a McGraw eight-gallon hot-dog-style air compressor that hovers around $170.

The Goodyear eight-gallon air compressor is a fantastic choice for those looking for a quiet, potent compressor. Despite its large eight-gallon tank and 54-pound weight, the unit is quite portable, thanks to its integrated handle and wheels.

Our testing registered max psi of 130, just 5 psi short of its stated 135 psi max. Impressively, it has a decibel level of just 77, a relatively reasonable number considering it has a 1-hp motor attached to the top. The unit took approximately 3 minutes, 46 seconds to fill the tank, a respectable time considering the size of the motor and tank.

As a whole, this unit delivers, offering solid performance in a (relatively) quiet package that's surprisingly maneuverable given its size. As a bonus, it can be tilted to stand upright so it takes up less floor space when not in use.

The California Air Tools compressor (CAT-4610AC) offers superior performance with an emphasis on quiet operation. It has a 4.6-gallon tank and a running horsepower of one, which makes for a quick fill-up time of just 1 minute, 52 seconds.

During compression, it had an average volume of 83 decibels, which is reasonable given its 1-hp motor. It weighs 44 pounds and has an integrated handle, but it can be slightly awkward to carry at times, particularly if you're smaller-statured.

The tested max psi matched the stated 120 psi, and overall the unit was nice to use with the dual-gauge design and double outputs for powering two tools at once.

This compressor is an excellent option for those looking for a balance between performance and low noise levels in a relatively compact compressor.

This cute little creature is the Senco PC1010 air compressor, a compact hot-dog-style air compressor ideal for small, precision tasks.

With a one-gallon tank, it's extremely lightweight and portable at only 20 pounds. It has a relatively quiet operation with a decibel level of 78 and takes roughly 2 minutes, 25 seconds to match the stated max psi of 135.

The wrap-around handle, combined with the unit's low weight, made the Senco easy to move around, and its compact size makes it simple enough to store. In fact, you could easily set it in a closet or even under a storage container to further cut down on the noise.

If you need a high-capacity model that'll allow you to work for an extended period before refilling, this isn't the one for you, as it powered the Craftsman half-inch impact driver for just shy of 10 seconds. Senco does make higher-capacity models, so those with more demanding tasks can simply scale up.

As it stands, this air compressor is perfect for those who require a compact and portable unit for light tasks.

The Stealth 12-gallon Quiet compressor (SAQ-11215) is designed for heavy-duty applications and has the largest capacity of the units we tested. It features a 12-gallon tank with a tested max psi of 138, which comes in 12 psi short of its stated max.

The unit weighs 88 pounds but is still manageable thanks to its wheels and handle. It operates at a relatively loud 94 decibels, the second loudest of the bunch—ironic, considering this compressor is marketed as a much quieter alternative to its competition. From empty to full, it took about 5 minutes, 36 seconds.

Its large capacity is nice and its psi is reasonable, but other options in this list are available with 12-gallon capacities and are either quieter and/or have a higher max psi (in some cases, both).

After putting together all of the air compressors, which consisted mainly of attaching various handles and wheels, we weighed each model, complete with all the attachments that came with it in the box.

We then measured how long it took each compressor to fill from entirely empty to completely full, taking note of how much time it took and how high the maximum psi was compared to the claimed max psi listed on each box. We tested the usable capacity by filling each compressor up to maximum capacity and disconnecting the power. We then attached a half-inch Craftsman pneumatic impact wrench—using an identical hose for each—and measured the amount of torqued lug nuts the compressor allowed us to remove.

We also tested noise level during compression with a decibel meter to see how the actual readings stacked up against manufacturer claims. Other details we noted throughout our testing included ease of use, portability, and any included attachments. These data points and subjective notes on all of these parameters helped us decide on the best portable air compressors.

What type of air compressor is best for home use?

For most homeowners, a portable electric air compressor is sufficient. These are ideal for inflating tires, running smaller power tools, and performing DIY tasks around the house.

How much psi do I need in an air compressor?

The required psi depends on the tasks you intend to perform with your compressor. For inflating car tires, 90 to 100 psi should be enough. However, if you plan to use pneumatic tools, you'll likely need a compressor with a higher psi and volume rating.

What's the difference between a single-stage and a two-stage air compressor?

A single-stage air-compressor motor compresses air to its max pressure in one stroke, while a two-stage compressor does it in two. The latter is more efficient for heavy-duty applications. Two-stage compressors are typically found in industrial settings, while single-stage models are more common for residential use.

Do I need an oil-free air compressor?

Oil-free models are generally more user-friendly as they require less maintenance, making them a good choice for casual or infrequent use. However, they may not last as long or run as quietly as models that require oil.

Should I consider a compressor with a larger tank?

A larger tank doesn't necessarily mean a better compressor. Instead, consider the cfm and psi ratings, as these determine how many tools the compressor can power and how quickly it can perform tasks. A larger tank might be beneficial if you're running tools that require a constant supply of air for extended periods.

Can I use an air compressor to inflate any tire?

Most air compressors can inflate a variety of tires, including those used on everything from bicycles to trucks. However, it's crucial to check the maximum psi of the compressor and the recommended psi for the tire to ensure compatibility.
