The Best Portable Air Compressors for On-the-Go Power, Tested
Hello, my friend, hello again; today we come together to talk about The Best Portable Air Compressors for On-the-Go Power, Tested and hope the blog can help you.
Equip yourself with a high-performing portable air compressor to get jobs done quickly and efficiently.
Pneumatic tools powered by a portable air compressor can save lots of time on various projects, whether at home or at the construction site. One of the biggest benefits of a portable air compressor is that it allows you to use lightweight power tools. Driven by an air compressor, pneumatic power tools don’t need to be equipped with a heavy motor of their own.
You can buy a range of high-quality pneumatic tools, but at the end of the day, an air-powered tool is only as good as the compressor powering it. We tested today’s most popular portable air compressors in our workshops and on jobsites to see how well they fared in real-world applications. We were surprised and impressed by some of the new models’ power and quietness.Read on to find out how the following models earned a spot in this tested lineup of today’s best portable air compressors.

Before You Buy a Portable Air Compressor
Portable air compressors can be a tremendous help in both DIY and professional settings. However, a larger air compressor might be better when working in a shop scenario because it will generate greater and more consistent volume. If, on the other hand, you’re looking to bring the compressor with you, a portable model is the way to go.
How We Tested the Best Portable Air Compressors
With dozens of highly rated air compressor models to choose from, we needed to narrow the field to the top performers in various categories and test just those. We considered brand names to an extent; after all, reputable manufacturers such as Makita are known for their high-quality tools.
We narrowed the field further by only considering models that weigh 90 pounds or less. While many of our readers can easily lift and load heavier models on trucks, we felt 90 pounds was a good cut-off point, and we were looking for other portability factors, such as wheels and handles.
We assembled the models as they arrived, filled crankcases with oil (if necessary), installed air filters, and started them up. We then connected air-powered tools that were suitable for use with each specific compressor based on pressure requirements, and we used the tools as we normally would. We noted cycle run/recovery times, pressure consistency, and ease of use and paid special attention to portability factors. We awarded points based on a rubric: The better a compressor performed on a test, the more points it earned. After testing, we averaged the points to determine our top picks and award each product its own distinction based on its standout qualities.

Best Overall
Makita MAC2400 2.5 HP Big Bore Air Compressor
Our Ratings: Ease of Use 5/5; Power 4.5/5; Noise 4/5; Portability 4/5; Value 5/5
Product Specs
- Power source: Corded, electric
- Tank size: 4.2 gallons
- Maximum pressure: 130 pounds per square inch (PSI)
- Cubic feet per minute (CFM) at 90 PSI: 4.2
- Weight: 77 pounds
Pros
- Dual hose ports allow users to run 2 tools at a time for better workflow
- Simple to store when not in use thanks to its compact design
- Easy-to-read oil gauge makes it simple to keep an eye on the oil level
Cons
- Single regulator knob for both ports limits simultaneous dual-tool use to similar pressure requirements
Makita’s MAC2400 features a snazzy, twin-stacked tank design with 4.2 gallons of air volume. This is one of only a few oil-based models we tested, so we first filled the crankcase with oil (included), and then we installed the air filter. That was all, and it was ready to go.
With a 2.5-horsepower (hp) motor, this compressor can push 4.2 CFM at 90 PSI, so it’s well suited for inflating tires and powering brad nailers and staplers. We plugged it in, turned it on, and it quickly cycled up to its maximum, 130 PSI. We attached a nail gun and shot 12 nails quickly before the MAC2400 cycled on to replenish the tank’s air pressure. Not bad. We also tried it out with an impact wrench and loosened two lug nuts before it cycled on. So, it does have the power to run an impact wrench, but it will cycle frequently.
We like the compressor’s dual hose ports for running two tools at a time, and the built-in roll cage provides insurance against an accidental drop or fall. At 77 pounds, this compressor is near the upper end of being portable, but during our tests, its compact size and nonslip carry handle made it easier to lift and load. Our takeaway? The MAC2400 offers a solid combination of air power and portability for light-duty pneumatic tools.

Best Bang for the Buck
Master Airbrush ⅕ HP Cool Runner II Air Compressor
Our Ratings: Ease of Use 4.3/5; Power 5/5; Noise 5/5; Portability 5/5; Value 4.7/5
Product Specs
- Power source: Corded electric
- Tank size: 0.79 gallons
- Maximum pressure: 57 PSI
- CFM at 90 PSI: N/A
- Weight: 12.35 pounds
Pros
- Lightweight and portable; easy to carry and use virtually anywhere
- Powers a standard airbrush for several minutes before cycling on
- Quiet operation, and the compressor comes with 2 holders for airbrushes
Cons
- Initially had a loose fitting that was causing the tank to lose pressure
Not all compressors are designed for running loud power tools, nor are they all pricey. Those who are looking for a lower-pressure unit—the type typically used for airbrushing fine designs on furniture, hardwood floors, or models—may want to consider the Cool Runner II by Master AirBrush. It’s an affordable option that’s ideal for those who need minimal pneumatic power.
Weighing in at just 12.35 pounds, the Cool Runner II was easy to carry around our workshop and out to the yard for testing. We plugged the compressor on, flipped the power switch, and it quickly cycled to its maximum 57 PSI capacity. However, when the cycle ended, we saw the needle on the pressure gauge slowly dropping. It shouldn’t have been doing that, but we couldn’t hear any air escaping. Still, there was a leak. We checked every fitting and sprayed water with dish soap on the connections. Sure enough, one started bubbling. After discovering the source of the leak, we tightened the nut, successfully halting the tank’s pressure loss.
To test the Cool Runner II, we attached an airbrush (not included) and loaded paint in the airbrush’s reservoir. We painted long, short, heavy, and light strokes. The Cool Runner II didn’t cycle on for more than 5 minutes, and when it did, we were able to continue painting while it recovered. The Cool Runner might be the ticket if you’re looking for a small, dependable compressor to run an airbrush. It is quiet yet powerful for its tiny size, and hopefully, you won’t need to tighten any nuts.

Best Compact
Makita MAC210Q Quiet Series 1 HP Air Compressor
Our Ratings: Ease of Use 5/5; Power 5/5; Noise 5/5; Portability 4/5; Value 4.3/5
Product Specs
- Power source: Corded electric
- Tank size: 2 gallons
- Maximum pressure: 135 PSI
- CFM at 90 PSI: 2
- Weight: 45.2 pounds
Pros
- Does not take up much storage space thanks to its small footprint
- Relatively light weight coupled with a padded carry handle enhances portability
- Generates just 60 decibels (dB) of noise; very quiet by air compressor standards
- Well suited for light to medium tasks, including brad nailing, stapling, and inflating
Cons
- Not enough power or tank capacity to run heavier-duty tools
If you’re looking for a portable, compact air compressor for light- to medium-duty tasks, such as brad nailing, stapling, and inflating, you won’t go wrong with the MAC210Q from Makita. This bright aqua-toned compressor weighs 45.2 pounds and is equipped with a sturdy roll cage that protects the motor from accidental drops or falls. It’s designed with a 2-gallon tank and has a maximum pressure of 135 PSI. It also features a nonslip padded handle that makes carrying it more comfortable.
We tested the MAC210Q for firing brads in hardwood trim and inserting construction staples in plywood sheeting. We also tried it with our airbrush, although this compressor is oversize for airbrushing. It worked well in all our tests and had a quick recovery time, so we didn’t have to stop firing brads or staples as it cycled.
Something that stood out to us is just how quiet the MAC210Q is while operating. It generates just 60 dB, making it well suited for installing decorative or detailed trim indoors where noise levels are a concern. It delivers 2 CFM at 90 PSI, so it’s not quite powerful enough to run an impact wrench or a pneumatic sander, but it’s a great little portable compressor that won’t take up a lot of room on the job or in storage. It measures just 17.375 inches long by 16.875 inches wide by 13.625 inches high.

Best Compressor Kit
Bostitch 3-Tool Air Compressor Combo Kit
Our Ratings: Ease of Use 5/5; Power 4.5/5; Noise 4/5; Portability 5/5; Value 5/5
Product Specs
- Power source: Corded electric
- Tank size: 6 gallons
- Maximum pressure: 150 PSI
- CFM at 90 PSI: 2.6
- Weight: 45 pounds
Pros
- Delivers enough air power to run a framing nailer and other power-intensive air tools
- Comes with 3 high-quality Bostitch tools: a finish nailer, crown stapler, and brad nailer
- At 45 pounds, it’s lightweight enough to haul up on a roof
Cons
- Not a super-quiet air compressor; at 80 dB, it’s best suited for outside projects
If you’re looking for a combination of power and portability, check out the 6-gallon pancake-style air compressor from Bostitch. It produces 80 dB of sound while running, so it’s not the quietest model we tested, but it delivered enough power to run a framing nailer, and we used it on the job for roofing.
We’re big fans of Bostitch—their staplers and small brad nailers are top-notch. Aside from the air compressor, this kit also includes three air tools: an 18-gauge brad nailer, a 16-gauge finish nailer, and a 0.375-inch crown stapler. To test the air compressor, we used it to power all three of these air tools, and it provided ample air power for each. The Bostitch compressor also comes with an air hose, which is nice since many models don’t.
With a maximum pressure of 150 PSI and a delivery rate of 2.6 CFM at 90 PSI, this portable air compressor produces enough power to handle a range of DIY and pro tasks. It weighs 45 pounds, making it substantial yet light enough to haul on a roof when installing sheathing and shingles.
In addition to testing with the three tools that came with the air compressor, we also used it with a pneumatic impact wrench. It delivered the power we needed to remove lugs. The Bostitch combo kit is a clear win for the manufacturer and an excellent pick for enthusiastic DIYers.

Best for Inflating
EPAuto 12V DC Portable Air Compressor Pump
Our Ratings: Ease of Use 4/5; Power 4/5; Noise 5/5; Portability 5/5; Value 4.5/5
SPECS
- Power source: Corded electric, DC-12 volt
- Tank size: 0.92 gallons
- Maximum pressure: 70 PSI
- CFM at 90 PSI: N/A
- Weight: 3.7 pounds
Pros
- Lightweight, compact, and highly portable; ideal to stow in the trunk of a car
- Plugs into a car’s 12-volt port (cigarette lighter) for power anywhere
- Can be used to fill up bicycle tires as well as car tires
- Having an inflator-type air compressor in the car ensures you can fill up tires anywhere
Cons
- Not powerful enough to inflate heavy-duty truck tires
If you’ve ever had a car tire with a slow leak, you know how nerve-racking it can be searching in vain for a service station with an air-pressure pump for fill-ups. The alternative is to check and fill up your tires with a shop compressor before you leave home—which is a good idea—but that won’t help you if you’re already driving in your car and you can’t find an air-pressure pump.
The solution? Stow the EPAuto 12V portable air compressor in your car’s trunk for easy tire inflating—no matter where you are. The EPAuto isn’t going to power any DIY tools, but it’s not designed for that. It’s designed to inflate automobile tires, and we found it quite capable of doing that. We purposefully released the air from some of our car tires and then used the EPAuto compressor to fill them back up to the recommended pressure.
The little unit comes with a 12-volt DC plug (for cigarette lighters in cars), and as soon as we plugged it in and flipped it on, it started cycling. It has a digital gauge, and we scrolled through several metric measurements to find the PSI level. It comes with a valve for filling auto and bicycle tires, and we filled up both.
It delivers a maximum of 1.06 CFM, which is enough to fill most types of car tires and bike tires but not quite enough to fill heavy-duty truck tires. It weighs just 3.7 pounds and comes with a 12-foot plug-in cord, so you’ll be able to reach any tire on your car.
