The Best Portable Air Compressor of 2021 (Reviews & Buyer`s Guide)

The air compressor pump is one of the most essential tools in any workshop, be it an industrial one or a small home DIY setup.

From spray painting to using it in your woodworking to filling up a gas cylinder, there are umpteen tasks around the house that can be completed effortlessly and quickly with an air compressor pump.

And contrary to popular notion, you don’t need a large stationary model that costs a bomb and makes more noise than what your eardrums can absorb. A compact portable air compressor pump usually suffices for most home repair jobs as well as a few basic industrial ones.

The caveat, however, is to get the one that is most suited for your particular application. Portable Air compressor pumps are all about specifications and if you do not get the right specs for your job, then you may end up with one that is an expensive mistake. Here’s a small guide that helps you understand some of the basic features to look for while buying air compressor pumps.

Things to consider while shopping for the right portable air compressor pumps

There are a lot of specifications that you will be bombarded with when you go shopping for air compressors. Some of them can be misleading and can even veer you towards a wrong buying decision.


This is the most common specification of an air compressor that is thrown around. It stands for ‘pounds per square inch of air’ and it means the force of air that is generated by the compressor.


The CFM is undoubtedly more important than the PSI because it stands for the volume of air that the pump generates. In simpler terms, this number determines how fast the compressor pump supplies air to the tool Irrespective of whether you are using it to pump a tire or running pneumatic tools, you want to ensure a seamless workflow. If you get the CFM wrong, then you will have to wait until your air compressor pump catches up with the demand of the tool.

Receiver tank

The receiver tank or the capacity of a portable air compressor pump is usually 5-10 gallons and is pretty much enough for basic tasks. If you are using specialized tools, then you may look at tanks with higher capacity because it will allow you to work for a longer time before the air pressure begins to drop and the pump has to be refilled again by the motor.

The Sound

This is the single specification in air compressor pumps that most people get wrong. While air compressor pumps normally work at 60 decibels, some can go as high as 80 decibels or more. That may seem like a small increase. The fact though, is that 70 decibels can be twice as loud as 60 decibels. 80 can almost quadruple the sound.

Air-line hook up

Some portable air compressor pumps feature a dual air-line hookup option that allows you to connect two air-lines. These are however found only on higher-end machines that have a PSI above 180.

Gas Powered vs. Electric

Electric portable air compressors are clearly better suited for repair tasks indoors as well as for emergency situations. For example, if you blow your tires on the road, then an electric compressor pump can be connected to your battery. A gas-powered motor is usually used in a garage set up.

Last but not least, it is always better to choose an air compressor pump that is a proven warhorse rather than getting swayed by schmancy advertising. A good positive customer rating is an indicator that the unit has a proven track record and there are very little flaws with the performance.

  1. I have a friend that has a DEWALT (the model you talk about on this page) and while he’s happy with it he said that my Porter-Cable C2002-WK might be better. The two are similarly priced but from what I can tell, my Porter is better. A few of the things I like and that probably make this the best air compressor pump are: it’s very silent, a big accessory kit and very portable. Also, I bought it for less than $120 so it was a real bargain.
