The Best Portable Air Compressors of 2024

Here are the 7 best portable air compressors money can buy.

Craftsman Pancake Air Compressor

Best Portable Air Compressor for Home Garages

This Craftsman is a pancake compressor, so it is compact and light and still has a 6-gallon capacity. It generates an SCFM of 2.6 at 90 PSI, so it should power your air impact wrench and air hammer.

It also generates a maximum PSI of 150, so it can inflate your car and truck tires effortlessly. What makes this the ideal home garage air compressor kit is the 13-piece accessory set. You can get to work straight out of the box. It comes with a PVC air compressor hose, a blowgun, a tire gauge, an OSHA-certified safety nozzle, and 3 inflator adaptors. So, getting the kids swimming pool ready will take no time at all.

The pump is oil-free, which increases the compressor’s running life and reduces the need for maintenance.

What We Like

Oil-Free Pump

If you want a maintenance-free compressor, choose one with an oil-free pump. It reduces the need for you to service it, and it is better for the environment because it requires no harmful lubricant.

150 PSI

Increasing the PSI value means you can inflate all manner of tires, from the SUV to your truck. Also, it is powerful enough to drive air tools, which increases your flexibility inside your garage.

13-Piece Accessory Set

Get started straight out of the box with the 13-piece accessory set. It comes with the hose, adaptors for different inflatables, and an OSHA-approved safety nozzle. You have everything you need at no extra cost.

High Satisfaction Score

This compressor is extremely popular, both in sales numbers and the satisfaction rating. It’s the reason why it tops our list. Customer feedback is one of the best ways to gauge the truth about a product.

What We Don't Like

Quality Control Issues

Some people have complained that parts were missing when the compressor was delivered, and others are frustrated because the compressor stopped working after a few uses. Low cost can mean low quality.

User Experience

My experience with this compressor has been largely positive. It's sure to make you jump when it kicks in, but it does the job efficiently, delivering the pressures I use for auto, bicycle and RV tires, as well as air mattresses and pool toys. The hose seems a bit inferior in quality compared to professional-grade ones, but it hasn't torn up yet. I do appreciate the included hose accessories. Living in Florida, I've noticed I need to drain the condensed moisture from the tank more often during the summer, but the valve for this task works well.

Viair 00088 88P Portable Air Compressor

Best Portable Air Compressor for Tires

If all you want is a compressor for inflating tires, this Viair model is a great choice. It is small, lightweight, cheap, and stores easily in your trunk, ready for emergencies. It connects directly to your car battery via clamps and generates a maximum PSI of 120 and 1.47 CFM at freeflow.

It is a 12-volt compressor, so it uses almost zero power, and yet it is powerful enough to inflate the tires of ATVs, SUVs, and trucks with a tire size of 33 inches. It has a 16 ft air hose, a 10 ft power cord, and a 3-piece inflator tip kit.

It won’t match other compressors for versatility and power but it is all you need to inflate tires, air beds, swimming pools, and beach toys.

What We Like

Connects To Your Battery

Thanks to strong clamps, this compressor is powered directly from your battery. It means you have an extended reach, which is ideal if you are coming to the aid of other motorists in their hour of need.

120 PSI

It has enough punch to inflate SUV, truck, ATV, and sedan tires, as long as they do not exceed 33 inches. It is the ultimate emergency compressor.

3-Piece Tip Kit

Having interchangeable tips gives you the ability to inflate tires, balls, beach toys, and air beds. And in the height of summer, you can drag the swimming pool out to keep the kids entertained.

What We Don't Like

Limited Uses

Other than inflating tires, you are limited in what this compressor can do. It is more of an emergency tool that sees the light of day once in a while to inflate flat tires.

Pricey

For such a small compressor with limited uses, this model only costs a few dollars less than some larger and more powerful compressors with far wider uses.

Personal Perspective

For anyone who needs a reliable, efficient, and high-quality compressor, this compressor is worth considering. I've used it multiple times over the years and it never disappoints, filling tires in a minute or two, which is faster than many other compressors I've used. It has a long cord and hose, which makes it easy to reach all four tires, and it remains cool even after prolonged use. Although the LED light is not very strong, the overall performance and durability of this compressor more than make up for it.

Makita MAC2400 Big Bore Air Compressor

Best Portable Air Compressor for Air Tools

When you need an extra punch to power your air tools, this Makita Big Bore is the compressor to consider. It generates 4.2 CFM at 90 PSI, which is pretty impressive for such a small device. It also has a 2.5 HP 4-pole motor, which increases productivity and reduces the running noise of the compressor. While it isn’t the quietest to feature, 79 dB is pretty good.

This is an industrial compressor, so it will handle your air tools, thanks to the twin stacked tanks with a capacity of 4.2 gallons and generate a maximum operating PSI of 130. It has a robust design, making it job-site ready, and the cast iron pump with its big bore cylinder and piston provides a faster recharge time when the tank empties.

This is not a cheap option, but it is a powerful and yet compact compressor that delivers.

What We Like

Made of Tough Material

The cast iron pump benefits from a big bore cylinder and piston, which is long-lasting and increases the compressor’s efficiency to improve refill times. It all adds up to less wasted and more productive time.

Powerful Airflow

Airflow is the number one consideration when you shop for a compressor because it represents how powerful the compressor is. You can have all the horsepower and PSI, but if the airflow is weak, the compressor can’t power your tools.

Job-Site Extreme

This Makita is encased in a roll cage, making it super-tough. It can withstand the rigors and punishment of the construction site or commercial environment, and yet, it is portable.

What We Don't Like

It may be portable, but this compressor weighs over 80 pounds, and without wheels, will be heavy to carry.

Expensive

This compressor is not a budget model. It costs double the price of the Craftsman, making it an expensive purchase for a compact compressor.

Oil-Lubricated

Oil-lubricated compressors produce more power, but they also increase harmful waste with old engine oil. Disposing of it is bad for the environment.

Community Feedback

This compressor has been a solid addition to my tool collection. Unlike my previous unit, it's notably more quiet, making it a pleasure to use. Despite its hefty weight, the impressive power it delivers when running various air tools, from nail guns to paint sprayers, has been a rewarding trade-off. The Makita compressor's construction is robust and well-thought-out, with easy-to-read gauges and low vibration. Though initially covered in a light film of oil, a quick clean up had it ready for action, and it has been running smoothly ever since, especially after I switched to a high-quality synthetic oil.

Porter-Cable C2002 6-Gallon Air Compressor

Best Cheap Portable Air Compressor

For the price-conscious, check out this Porter-Cable model. This pancake compressor generates a maximum PSI of 150, with 2.6 CFM at 90 PSI. The 6-gallon tank stores more air for tool running time, and the low-amp, 120-volt motor starts quickly in cold conditions.

This compressor is stable, thanks to the addition of rubber feet, and the drain valve lets you clean moisture out of the tank to prevent corrosion. Unlike the Makita, this compressor has an oil-free pump for longer life and maintenance-free convenience.

It has a shroud to protect vital components from damage and the elements, and a large carry handle makes lifting this 30-pound device a breeze. And for safety, it has built-in automatic thermal overload protection.

What We Like

Oil-Free Pump

Oil-free pumps are easy to maintain, last longer, and are better for the environment because you never have to dispose of old oil.

6-Gallon Tank

The 6-gallon capacity gives you the freedom to tackle larger jobs, and the CFM rate means there is a faster recharge when it empties.

Affordable Price

Porter-Cable has managed to produce a powerful and affordable compact compressor. Compared to some on the list, this is positively cheap.

What We Don't Like

No Accessories

Unlike the Craftsman model, if you want the extra kit, you have to buy it. Hose attachments and nozzles aren’t cheap, so they could increase your spend considerably.

Noisy

This compressor is louder than the competition. It produces 82 dB, which puts it at the top of the noise charts as things stand. That is noisier than a domestic vacuum cleaner.

First-Hand Impression

This compressor has been a reliable tool in my garage for five years now. I've found it incredibly useful for various tasks, from breaking bolts off my lawn mower to inflating car tires. Despite its noise level, which can be a bit startling, its dual ports, quality craftsmanship, and excellent performance make up for it. While it may not be intended for continuous duty, it's super easy to operate and move around, making it a great value for the money.

California Air Tools 8010A Air Compressor

Best Quiet Portable Air Compressor

For those seeking a quieter life, getting an air compressor to better this California Air Tools model for decibels is pretty tricky. It runs at 60 dB! By anyone’s standard, that’s impressive. It’s the equivalent to the volume of a normal conversation.

It has a maximum pressure of 120 PSI, so it’s not the most powerful machine to make the review, but it does have a dual-piston pump with a life cycle of plus 3,000 hours. This compressor uses an oil-free pump, so you won’t have to fork out for new compressor oil or dispose of the old oil in the landfill.

So, it’s low maintenance, produces cleaner air, and starts on cold mornings with minimum fuss. It has an airflow of 2.2 CFM at 90 PSI and 3.1 CFM at 40 PSI.

What We Like

Super-Quiet

If you work in an environment where noise is a problem, this compressor will make things a little easier, thanks to the 60-decibel running volume. That’s a difference of 20 decibels compared to some models.

Fast Refill Time

When the tank runs low, you won’t have to wait long for it to refill. This compressor recharges from empty to full in just over 2 minutes. It means you can spend more time making money and less time standing around.

Oil-Free

Oil-free pumps require almost zero maintenance and produce cleaner air because there is no oil residue to contaminate. Also, they are cheaper to run thanks to not needing fresh compressor oil.

What We Don't Like

Lacks Power

You might want to save this compressor for lighter duties. It only has a 1 horsepower motor and produces 2.2 CFM at 90 PSI. That is low compared to some of the other compressors to feature.

User Experience

I have found this air compressor to be impressively quiet, allowing me to work late into the evening without noise complaints. Its compact size is deceptive as it matches the pressure of my old ten-gallon unit, and despite a very slow air leak that empties the tank overnight, its overall usability is not significantly impacted. The aluminum tank construction makes the unit lightweight and rust-free, and even though some may find the regulator fragile, I find it perfectly adequate for my stationary setup in my garage.

EPAuto 12V DC Portable Air Compressor

Best 12V Portable Air Compressor

This EPAuto hand-held compressor fits into the trunk of your car, stored away for emergencies. It’s small, light, and highly portable, which is why it is the best choice for inflating car tires.

It plugs directly into your 12-volt socket in the car and produces a maximum of 70 PSI. It inflates all car tires except truck tires because it lacks the capacity. It has an easy to read digital display that shows kPa, bar, PSI, and kg/cm, and it also has an auto shut-off to prevent over-inflation.

This tire compressor has notched up sales exceeding 15,000 units. It had to be our choice for the best 12V compressor.

What We Like

Portable and Light

It only weighs 1 pound! Plus, it measures 13.5 inches x 8.1 inches x 5.6 inches, making it small enough to pack into the trunk of your car.

Easy To Read Display

This compressor has an easy to read display, making it simple to use and understand. You can also choose between bar, kPa, and PSI.

Handy Flashlight

It even has a handy flashlight, should you get a flat tire in the dark. Seeing clearly makes a huge difference because you can work more quickly to get the tire inflated.

What We Don't Like

Limited Use

Unless you are inflating tires, there is little else this compressor can do. It might inflate small items for the beach like rings and floats, but that’s about it.

Small Compressor, Big Cost

For such a small compressor, it is surprisingly costly. It still costs less than every other model featured, but given its limitations and lack of power, the price tag makes it seem expensive.

Personal Perspective

I'm impressed with the practicality and reliability of this air compressor. It's compact and doesn't take up much space in my car, plus it runs off the cigarette lighter port, eliminating the need for an internal battery which can falter in cold weather. It inflates tires at a reasonable speed and turns off automatically once the desired pressure is achieved. Despite being on the quiet side, it's surprisingly powerful. The LED light feature is a nice touch, although the carrying bag could be a bit more durable. All in all, this air compressor has proven to be a handy tool in situations like a slow tire leak.

NorthStar Portable Gas-Powered Air Compressor

Best Portable Air Compressor for Construction

This is the first gas-powered air compressor to feature, and it packs a punch. It is a go-anywhere tool, so it’s perfect for large construction sites where plugin power can be limited.

The pump head is constructed from FC35-grade cast iron, so you can bet it will last the distance. The motor is a Honda GX160 OHV, which has a low oil shutdown feature. The pump has superior cooling qualities, and the Swedish-style valves ensure a longer operating lifespan.

The CFM rate is 13.7 at 90 PSI, and the maximum PSI is 130. This is slightly less than the Porter-Cable model, but still plenty for most applications. The motor runs at a lower RPM to keep the efficiency and cooling qualities of the engine.

What We Like

Gas-Powered

Okay, we get that it weighs 196 pounds, but if you want complete portability, this gas-powered compressor can go anywhere. It works independently of an electrical supply, so it is ideal for the job-site.

Quality Honda Motor

The Honda GX160 OHV is a brilliant motor that delivers fuel-efficiency, better performance, and a longer lifespan. It also needs fewer services to keep it in working order.

Low Vibration Technology

Most of the noise generated by a compressor comes from vibrations. NorthStar has developed LVT (low vibration technology) to deliver a smoother operation when running the compressor. Less vibration preserves the integrity of the compressor and expands its lifespan.

What We Don't Like

Very Expensive

If you want to spend 3 times as much as the Makita model, this gas-powered compressor will suit your budget. But for most, it is well beyond their reach.

Loud

Gas-powered air compressors are loud. The tell-tale sign is when the company fails to advertise the decibel levels for fear of putting you off. This model is a lot louder than electric models.

Community Feedback

After two months of owning this air compressor, I've found it to be a fairly good unit, but it did require some initial adjustments. I had to disassemble it to modify the base for my service truck, and in doing so I discovered a misinstalled fitting that needed immediate repair. The provided vinyl/plastic tubing didn't meet my durability expectations, so I plan to upgrade to copper lines. Despite these setbacks, it has been effective for truck repairs and tire changes. Just be aware that you might need to make some tweaks to get the most out of this compressor.

What Are Portable Air Compressors Used For?

Portable air compressors have many uses. Depending on the capacity and the airflow, they can inflate tires, swimming pools, air beds, and beach inflatables. They are also great if you are an artist and like using spray paint guns.

Sculptors use them to power air chisels, and mechanics use them to drive impact wrenches and ratchets. You can even find air compressors at children’s parties to inflate balloons.

Types of Portable Air Compressors

The market is rammed with so many makes and models; it can be difficult to choose one. Let’s take a more detailed look at the various types available.

Air Inflators

Air inflators do precisely what their name suggests. They inflate tires, air beds, swimming pools, beach toys, footballs, bicycle tires, and pretty much anything that requires air. These models are typically smaller and easier to transport, making them the ideal choice to store away in a car trunk for emergencies.

Pancake Air Compressors

They get their name from their shape. They are compact and lightweight but provide slightly more power than air inflators. They typically come in 4 to 6-gallon tank capacities and have a PSI of 135.

The CFM values of a pancake compressor can vary, but you are doing okay if you are getting 2 to 4 cubic feet per minute. Pancake compressors best serve the domestic environment, but it is not unusual to see them in tire shops and garages.

Hotdog Air Compressors

Hotdog air compressors look like ballpark hotdogs, hence the name. They can range in size from 1 HP motors to 5 HP, and 6-gallon tanks up to 30 gallons. Compact hotdog compressors are a firm favorite with hobbyists and the occasional user at home, as well as professionals.

Twin-Stack Air Compressors

Twin stack air compressors have two tanks, stacked one on top of the other. The key advantage is it increases the capacity and also gives you a continuous supply of compressed air. They are lighter than hotdog compressors but heavier than pancake models.

Twin stack compressors are more likely to find use in the professional arena rather than the home market.

Portable Vertical/Horizontal Tank Air Compressors

Think of a hotdog compressor and add a large handle and two pneumatic wheels, and you have a portable horizontal compressor. The wheels and handle mean that you can scale up the capacity, even as much as 30 gallons, and still maneuver it with ease.

Vertical models have all the same attributes as their horizontal cousins, except they stand up. The advantage of this is they are easier to store, and they take up less room. If you work in a cramped environment, where space is a premium, a vertical compressor is the best choice.

Wheelbarrow Air Compressors

They are so named because they have twin tanks, one on either side for balance, and a large pneumatic wheel in the middle, just like a wheelbarrow. At the other end, there are two large wheelbarrow-style handles for better grip and maneuverability.

Most wheelbarrow air compressors are gas-powered, and they offer typical PSI and CFM values of 135 and 10 to 12, respectively. They are a go-anywhere tool, favored by the professional circuit and commercial settings.

What Size Air Compressor Do I Need?

The first thing to decide is the size of your project. Then you need to look at the air tool you’ll be using. From there, you can determine the size of the air compressor you will need. Most air tools operate at 5 cubic feet per minute (CFM), and you can find this out by consulting the owner’s manual.

The next key point is the air compressor’s CFM capacity. To work out if your tool is compatible, multiply the CFM rating of the tool by 1.5. So, if you are using a spray gun rated at 6.5, it means your air compressor must have a minimum of 9.75 CFM for the device to operate successfully.

Here’s a handy chart.

Air Tool CFM at 90 PSI Average Operating PSI
Air hammer 4 90-100
Angle grinder 5-8 90-100
Blow gun 2-3 90-100
Brad nailer 0.5 70-90
Die grinder 5 70-90
Disc sander 20 90-100
Drill 4 70-90

Impact driver 1-inch 12 90-100
Impact wrench 0.375-inch 3 90-100
Impact wrench 0.50-inch 4 90-100
Impact wrench 1-inch 10 90-100
Orbital sander 6-9 70-100
Paint spray gun 4-8 90-100
Ratchet 0.25-inch 3 90-100
Ratchet 0.375-inch 4 90-100
Speed saw 4 90-100
Staple gun 2 70-90
Tire inflator 2 125-150

The next consideration is the duty cycle. You can buy continuous cycle compressors that allow you to work without needing to stop as the motor cools. This is not important if you are using the compressor for lighter home tasks, but in the professional world, it is a significant factor. When you are against the clock, it could slow you down.

How To Choose the Best Portable Air Compressor

So, what are the key things to look for when selecting a new portable compressor? Is it weight, capacity, CFM, or all of them and more? Let’s take a look.

What Are You Using the Compressor For?

Some compressors work better for home and hobby use. They are smaller, lighter, and designed for infrequent operation. Inflating tires and air beds are a far cry from driving pneumatic tools. However, some are made of sterner stuff and like to be pushed to the max. They are the air compressors the professionals choose.

There is a distinct difference between the two, so choose one that best matches your requirements.

CFM Requirements

Your power tool’s CFM needs to be compatible with your compressor. It’s no good buying a compressor with a CFM value of 5 if your device has an operating range of 6.5 CFM.

You should always multiply the CFM rating by 1.5 to ensure the compressor is up to the task of delivering the correct airflow.

PSI Requirements

Knowing your power tool’s PSI rating is crucial to matching it with your air compressor. Most air tools work on about 70 to 90 PSI. You will need a 20 percent difference in the PSI of your device and the compressor.

If you are using an impact wrench with a PSI rating of 80, your air compressor needs to have a minimum operating PSI of 100 for the two to be compatible. If that differential does not exist, you will have an underpowered compressor and tool.

Tank Capacity

The tank capacity determines the length of the jobs you can do. Using a nail gun to fix a broken fence post will not tax your compressor unduly, but using it to erect an entire fence will. The tank’s capacity allows you to undertake larger projects and doesn’t slow you down between recharges.

Horsepower

Horsepower is not as vital as PSI and CFM because the pressure created and the airflow determine your compressor’s potency. However, horsepower still has a key role to play, in that once the tank empties, you want it to refill as quickly as possible, and the more powerful the motor, the faster the delivery.

How Loud Is It?

If you work in a built-up area, the noise your air compressor makes might disturb the neighbors. This is especially true when using the compressor at home. Most air compressors have a decibel rating between 70 and 90, which is akin to a vacuum cleaner at the lower end of the scale, and a car traveling at 60 MPH with all the windows open, at the other end of the spectrum.

According to the Occupational Safety and Health Administration, repeated exposure to volume levels above 85 dB can result in hearing loss (1). Buying the quietest air compressor you can has benefits for your health.

Pancake compressors have a large handle that makes them easy to lift. That said, they can still weigh 35 pounds or more. Bigger capacity compressors have wheels and a large handle, so while you may be scaling up the weight, you are increasing the device’s maneuverability.

Air inflators are the smallest and the lightest and are often found in car trunks for emergency flat tires.

Portable Air Compressor FAQs

Are Portable Air Compressors Worth It?

Portable air compressors can be invaluable around the house if you can actually use them. To determine if they are worth it, you must know more about their ups and downs and see if they match your needs.

These small air compressors are compact, so they are a must-have if you’re limited in storage space. They can usually be tucked in the corner of your shed or placed on a pallet inside your garage.

Their construction allows them to power up many tools around the house. They are suitable for air guns, spray painters, impact wrenches, air hammers, and other similar units. While their power is by no means a show-stopper, they are still really nice to have.

Investing in a portable unit is worth it if you work remotely and need to carry an air compressor here and there.

How Long Do Portable Air Compressors Last?

Portable air compressors last 10 to 15 years (at least) if you use them in your home or small shop. If your air compressor isn’t used daily and you perform regular maintenance as needed, you could enjoy it even more than 20 years.

Do I Need an Air Dryer for My Portable Air Compressor?

Most portable air compressors need air dryers, primarily if you use them to paint and need clean air. Some signs can help you determine if your portable air compressor needs an air dryer:

  • Does the product’s label specify it needs “dry air”?
  • Are the water spots coming out of your air tools?
  • Are the pipelines rusting?

The reason why portable air compressors need air dryers is because of moisture build-up. When this occurs, your air compressor is technically building up water inside. Not only does this lead to poor tool usage and sloppy jobs, but it will also damage your air compressor in time.

What Is the Best Portable Air Compressor?
