Looking to pick up a great small air compressor without any fuss and frustration? This American-made unit generates a maximum of 150 PSI and 2.6 SCFM at 90 PSI. Thanks to its durable, oil-free pump, this unit requires no maintenance while delivering long-term reliability. This small air compressor starts up easily in cold weather, and the dual couplers allow users to attach multiple hose and tool combinations for increased workspace efficiency. The 13-piece accessory kit also allows users to get up and running  straight out of the box, and a one-year limited warranty helps create peace of mind. At just over 30 pounds, the Craftsman CMEC6150K 6-Gallon Air Compressor is easily portable.

This small compressor puts out a significant amount of noise, although not as much as some. Rated at 78.5 decibels, this unit is quieter than a lawnmower but can still present a challenge to normal conversation.

For many jobs, size and portability outweigh the demand for industrial-level performance. The Campbell Hausfeld FP209499AV Portable Air Compressor is perfect for tackling small tasks that are less demanding. The small, three-gallon tank makes it easy to transport around the house or shop. Rated at a maximum of 110 PSI, this tank is perfect for inflating tires or balls and running airbrushes or nail guns. This air compressor is an oil-less, maintenance-free unit, and when the job is finished, this unit’s small footprint ensures convenient storage in virtually any location. The compressor also comes with a 10-piece accessory kit, including a coiled hose, inflating needles, blowgun, and fittings.

It provides users with a low 0.36 CFM at 90 PSI and generates a loud 93 decibels of sound. While it is not the best choice for large or long-term jobs, it can be great for miscellaneous household and DIY tasks.

Noise is an issue with most air compressors, yet this model manages to bring things down to an impressive 60 decibels. This unit is extremely lightweight for its size, weighing in at only 37.25 pounds, and this wheeled unit includes built-in handles to make this an extremely portable compressor. This unit boasts an eight-gallon, vertically oriented air tank with a maximum pressure rating of 120 PSI. Thanks to its aluminum construction, the tank is entirely rust-resistant, and the low-RPM, dual-piston motor generates strong performance at low decibel levels, providing 2.2 CFM at 90 PSI. The California Air Tools 8010A Ultra Quiet & Oil-Free 1.0 HP Air Compressor’s efficient design reduces power consumption, wear, and maintenance.

Arguably, the biggest downsides to this compressor are its price and size. This unit may push the definition of “small” for some users, and its premium features come with a matching price tag.

The Makita Air Compressor is an impressive unit for its size, delivering significant capability. This air compressor features a 4.2-gallon twin-tank system capable of providing a consistent 130 PSI. The 2.5 horsepower engine helps deliver a whopping 4.2 CFM at 90 PSI but does so at lower RPMs to minimize noise, and its maximum PSI rating allows users to run two pneumatic tools at once. The compressor’s low-amp draw reduces the potential of tripping circuit breakers upon startup, and the cast iron, big bore cylinder offers fast recovery, improving durability and system performance. The Makita Air Compressor also features a protective roll cage that doubles as a carrying handle for easy portability.

The motor utilizes an automotive-style air filter and oil system, adding weight and maintenance to the equation. As with many air compressors, this one also generates a fair amount of noise at 79 decibels.

More PSI means more run time for tools between cycles. The DeWalt Air Compressor has a six-gallon tank with a 165-PSI max rating and combines fast recovery and extended run time for improved productivity. The high-flow regulator and dual couplers increase pneumatic tool combinations and efficiency, and with a 75.5-decibel sound rating, this oil-free compressor is a little easier on the ears. Thanks to its pancake-style design, this unit is very stable during use, and at just 30 pounds, it is exceptionally portable. The high-efficiency motor starts quickly and easily in cold weather, even when connected to an extension cord. The DeWalt Air Compressor generates 2.6 SCFM at 90 PSI, but at 40 PSI, it bumps things up to 3.7 SCFM.

While this unit is quieter than affordable options, it still generates as much ambient noise as a vacuum cleaner. Still, users will be quite pleased with its noise level.

The Senco PC1010 1-Gallon Compressor creates excellent power without destroying eardrums or back accounts. This offering from Senco provides users with a one-gallon air tank rated to contain a maximum pressure of 120 PSI, and the oil-less motor generates 1.4 SCFM, perfect for smaller jobs in the house or the workshop. The engine runs at 1/2 horsepower while capable of a full horsepower peak output, and during use, it creates low noise levels for a pleasant working environment. Weighing in at a featherweight 20 pounds and featuring a roll cage with a conveniently-located handle, this compressor is the epitome of AC-powered portability. A one-year warranty also backs this air compressor. 

Due to its size and low CFM output, this unit is poorly suited to medium and large jobs, but for users running brad nailers and similar equipment, this compressor is more than equal to the task.

While one may be tempted to believe that power can’t come in small packages, the Bostitch Air Compressor quickly dispels such notions. This four-legged air compressor features a 1.2-gallon tank with a maximum PSI rating of 150 and generates 2.8 SCFM at 90 PSI. The powerful motor runs at 1.5 horsepower and draws 12 amps for effortless, no-hassle startups. The air tank, oil-less motor, and integrated control panel all reside inside the protective roll cage, and once turned on, the entire unit generates a reasonable 72 decibels of noise. The Bostitch Air Compressor also includes a convenient LED-lit power switch, making it easy to tell when it’s ready for work.

At 23.5 pounds, it is slightly heavy for its size, though still quite portable, and while 72 decibels is not ear-splitting by any means, it is still a little loud in the grand scheme of things.

Even when the closest AC outlet is miles away, this air compressor generates an impressive amount of air pressure. This tankless unit relies on 12-volt car batteries to power its 1/3-horsepower oil-less motor, and the 30-amp inline fuse protects the battery from surge-related damage. The direct drive motor creates a continuous duty cycle capable of generating 40 PSI for 40 minutes in 85-degree temperatures (Fahrenheit). This compressor generates a maximum airflow of 5.65 CFM, and the 24-foot coiled hose’s long reach guarantees easy tire inflation on any Jeep, truck, or ATV. The auto-shutoff feature protects the unit from overheating, giving users of the Smittybilt 2781 5.65 CFM Universal Air Compressor excellent peace of mind.

The cleanable air filter does require occasional maintenance, although no oil changes are necessary. This incredibly capable unit does come with a high price tag and couplers that require proprietary fittings.

This 12-volt compressor relies on automotive-style batteries to generate power via the attached alligator clamps. This free-flow air compressor draws 20 amps for startup and is capable of generating up to 120 PSI. With a CFM rating of 1.47 at 90 PSI, it is best suited for tire inflation on light-duty vehicles with up to 33-inch tires. Additionally, buyers will receive a 12-foot air hose, a solid brass twist-on tire chuck, and three adapter tips. It has an operating range of -4 to 158 degrees Fahrenheit.

This unit’s CFM translates to a meager 0.64 CFM at 90 PSI. While this is plenty of flow for tire care, it is too small to play with pneumatic tools. Also, the integrated pressure gauge requires the motor to stop before it can display an accurate reading.

In an emergency, the best air compressor is the one stowed in the trunk, and the Energizer Portable Air Compressor Tire Inflator is an excellent candidate to fill that role. This 12-volt compressor is ideal for roadside emergency kits as it is designed to draw power from the same auxiliary power outlets found in most vehicles. The 14-amp power draw protects the compact motor, and the pump can generate up to 120 PSI. The unit includes five built-in LED lights for use in low-visibility environments and a convenient carry handle and LCD screen for the pressure gauge. The air compressor is backed by a one-year hassle-free replacement warranty to provide you with assurance.

While this compressor does not list a CFM rating, it is safe to say that the number is quite low. That said, this unit can quickly get drivers back on the road in no time.
