Best Portable Air Compressor Options


Pneumatic tools that run by a portable air compressor can be a huge help and time-saver on a range of projects and at the construction site. Nail guns, for instance, drive fasteners with the pull of a trigger rather than pounds of a hammer. Impact wrenches can apply tons of torque and twisting power in seconds. Filling a truck tire will go from a nearly impossible task to a cinch with a tire inflator. All of these tools use the pressure and volume created by an air compressor.

A portable air compressor squeezes air into a metal tank, which it then releases through a hose to power a tool. Portable air compressors must be fairly lightweight and compact so one person can pick them up, wheel them around, or lift them into the bed of a truck with ease. To create a small footprint (which typically weighs between about 25 and 70 pounds), manufacturers keep tanks small and use lighter-duty motors. While this is great for portability, it often comes at the sacrifice of volume and serviceability.

What to Consider When Choosing a Portable Air Compressor

After considering how to choose the best power source to suit the project at hand, bone up on such important considerations as power, maximum pressure, and tank volume. Understanding these aspects will help narrow down the options to find the best portable air compressor for the job, whether it’s filling a flat tire or running a nail gun.

Types of Portable Air Compressors

Before purchasing a portable air compressor, consider the power source. Portable air compressors run on either electricity or gasoline. Each power source has its pros and cons, explained below.


Electricity is the more popular power source for portable air compressors. These machines plug into standard outlets and use an electric motor to pressurize the tank. They’re usually reasonably lightweight, and electric motors require very little maintenance throughout their lifetime.

Electric portable air compressors are a solid choice for home garage workshops and renovation projects, as there is generally an electrical outlet nearby to plug into. They don’t create exhaust, so they’re suitable for indoor use without worrying about carbon monoxide poisoning.

But electric compressors do have a few shortcomings. They usually aren’t serviceable, as the cost of replacing the motor, pump, and the necessary seals will often cost as much as buying a new compressor. Also, they’re not useful on construction projects that haven’t reached the electric phase, unless the site has a heavy-duty generator to supply enough power.

For those sites without electricity, a cordless compressor may be a good choice. These compressors run on a rechargeable lithium-ion battery to fill their tanks but otherwise work the same as a standard electric compressor. However, it’s a good idea to have more than one rechargeable battery on hand.


Gas-powered portable air compressors use internal combustion engines to pressurize their air tanks. Much of their quality depends on the manufacturer of the gasoline engine, the best-known manufacturers being Honda, Briggs & Stratton, Kohler, Generac, Subaru, and Kawasaki.

Gas-powered compressors can operate virtually anywhere, as long as there’s fuel in the tank. However, they tend to be a bit heavier than electric model compressors, so they’re somewhat less portable. They also require more maintenance, as they’ll need winterizing, an occasional oil check, and fuel filter and spark plug replacements from time to time.

While gas-powered portable air compressors are fine to use on outdoor construction sites and other places without power, they cannot be run inside a closed space, as these engines produce exhaust and can run the risk of causing carbon monoxide poisoning.


Air compressor motors are measured in horsepower ratings, and the machine’s power has a lot to do with its capability. While most air compressors have enough power for general needs, the more powerful the compressor, the faster it will fill its tank with air.

Horsepower can also affect how much maximum pressure a compressor can produce. Small electric motors should have at least 0.5 horsepower, while gasoline-powered options can benefit from as much as 5-horsepower engines.

Again, it’s important to consider the power source. For working primarily on renovation projects, an electric air compressor usually suffices. When taking tools on the road to remote locations, it might be worth considering a gas-powered compressor.

Maximum Pressure 

Portable air compressors have varying maximum pressures, which are measured in pounds per square inch. Some might pressurize to 120 psi, while others can produce up to 150 or even as high as 180 psi. Users can adjust the pressure with the regulator, checking the pressure gauge to adjust it to the correct pressure.

Maximum pressure is important to keep in mind because some tools require more pressure to work properly. For instance, most impact wrenches won’t operate until they reach 60 psi or so. Some nail guns may also require a bit more pressure. While a nail gun may have a working range of 90 to 120 psi, driving long nails into extremely wet or dense wood might require maximum pressure. That said, as a general rule, most compressors with more than 120 psi will typically be fine for projects around the house or workshop.

Tank Volume

The volume of a compressor tank determines how much compressed air the machine can hold. It also determines how often the compressor will run, how long it will run, and what the compressor can do.

Nail guns work with short bursts of air and so require very little volume—4- or 5-gallon tanks are usually enough for DIY projects. Conversely, air power tools like impact wrenches, cutoff wheels, and pneumatic reciprocating saws use much more air, as users hold their triggers down and let them run to do their job. For this reason, they require much larger tanks, or they will have to cycle on and off more often to maintain the tank pressure. In this case, 20-gallon tanks and larger are most helpful for running air tools and filling large objects, such as lawn mowers or truck tires.


Of all of the metrics manufacturers provide with their air compressors, airflow may be the most important. Described as CFM, this metric explains how much air the operating compressor can put out each minute while still maintaining pressure.

Essentially, a compressor needs to be able to run and maintain pressure for as long as a tool is in use. If a tool drains the pressure out of the tank, work will have to stop and wait for the tank to rebuild enough pressure to operate the tool.

While the proper CFM rating will depend on the tools the DIYer will use, most of the CFM measurements provided are at 90 psi. Look for compressors that can maintain at least 2.0 CFM at 90 psi.


To be considered portable, an air compressor must be lightweight enough to lift into the back of a truck or onto a shelf or be wheeled about with ease.

Look for an air compressor that is easy to lift (relative to the user’s strength). Generally speaking, pancake compressors—models that use round air tanks with motors atop—weigh about 30 pounds, making them a great choice for portability’s sake. Some double-tank compressors can offer more volume but weigh more than 70 pounds.

Those DIYers who are looking for a high-volume compressor but still want portability may want to check into a wheeled option. They come in both vertical and horizontal configurations and feature handles for wheeling them around.

Additional Features

Some additional features can help air compressors maintain durability or improve usefulness.

Built-in roll cages are steel or aluminum frames that protect the compressor. They’re especially helpful in scenarios where a portable compressor could fall from a truck tailgate.

Oil-cooled air compressors use oil to lubricate the compressor pump. This helps them stay cool, extending their lifespan. These models may include low-oil sensors that shut the machine down if there isn’t enough oil, which helps prevent the machine from running dry and overheating—two situations that could kill a compressor before its time.

Other additional features include easily operated petcock drain valves that allow for draining a compressor’s water buildup easily, quick-connect adapters, and thermal overload protection.


Occasionally, an air compressor might come with an accessory kit. This kit can be a great start for DIYers who don’t already have a myriad of air tools and fittings in their shop. These kits often come with tire inflators, quick-connect fittings, and blow-off chucks.

It’s sometimes possible to get a kit with a length of air hose or a set of nail guns. There are sets on the market that include the tools and fittings necessary to get up and running, significantly decreasing the amount of shopping you would have to do otherwise.

If an air compressor doesn’t come with a set of accessories, DIYers can purchase a separate accessory pack that includes the basic tools necessary to set up the air compressor (available here). Adding a separate tire gauge is also a wise idea, just to double-check the pressure once the tire is full.


If a portable air compressor seems like it might be a big help for certain projects, but you still want more info, consider the answers to some commonly asked questions below. For additional questions or concerns, reach out to the air compressor’s customer service number.

Q. How does a portable air compressor work?

Portable air compressors use a motor to operate a piston. The piston draws outside air into a chamber and then stuffs it into a tank. It continues doing so until the pressure builds up enough to operate tools and inflate tires.

Q. How do you set up a portable air compressor?

Most portable air compressors come set up out of the box. If one doesn’t, the most setup that could be necessary is to install a quick-connect on your hose port.

Q. How do you use a portable air compressor?

For electric compressors, simply plug it into an electrical outlet and flip the power switch on. Once the compressor builds up pressure, you can adjust the outlet psi with a built-in pressure regulator to match the tool’s requirements.

For gasoline-powered compressors, fill the fuel tank and check that the engine has oil in it. Flip the power switch to the on position and pull the pull-start cord until it starts.

Q. Why do portable air compressors come in various shapes?

The different shapes of compressors aren’t a functional design concern, so manufacturers can get creative with their designs. Sometimes separating the tank into two smaller tanks allows the compressor to have a lower center of gravity to aid in portability.

Other times, the designs simply take up less space. For example, a horizontal compressor can fit under a workbench, while a vertical compressor fits better in a corner.

Q. How much air pressure do you need in a portable air compressor?

This depends on the task. Bike tires and sports balls don’t require much pressure at all. On the other hand, pneumatic tools usually require 90 psi or more to operate effectively. If inflating something, look for the maximum pressure written on the item near the inflation valve.
