Best Portable Air Compressors Buying Guide

What do they do?

Portable air compressors are used to inflate anything from balloons to car tires, and they can be a really useful piece of equipment to have in your arsenal. They are available to purchase in a variety of 12v power or battery-powered models, depending on how powerful a piece of equipment you’re looking for. 

You can also find air compressors which are able to fill gas cylinders with highly pressurized air or to power industrial tools, although these are not portable and are designed more for industrial use.

The inflation of vehicle tires is most likely the main purpose of portable air compressors, and most of them will perform this function. Being able to inflate other items is a secondary feature, and one that will vary between models. 

Portable air compressors work by using a single motor to produce kinetic energy from the power source, by converting its electrical energy. Skipped a few too many science lessons in school? Guilty. In simpler terms, they send air through a compressor hose to pump up any deflated item. 

Size and Portability 

Just like us humans, portable air compressors come in all sorts of various shapes and sizes. That’s pretty much where the similarities end. You’ll need an air compressor that’s capable of performing its intended functions, but too big and you’ll lose some of its easy portability.

For vehicle tire inflation, portability is going to be a more important factor as it will need to travel with you, therefore you won’t want it to take up too much space in your car. For that reason air compressors designed specifically for this use tend to come in smaller sizes.

The size of the compressor tank will also affect the overall size of the portable air compressor, as they’re available in different shapes. With great size comes great power, and larger portable air compressors are designed to suit more industrial needs. You can choose between vertical or horizontal, which are similar except for placement, or you can decide on either pancake or twin-tank. 

There’s a bigger difference between the latter two types of compressor tank which will affect their overall performance. Pancake compressors have a single cylinder, whereas twin-stack models have a vertical placement which provides a larger capacity for air. Pancake compressors are thus suited to smaller jobs, and the higher CFM and PSI values of twin-stack compressors mean they are capable for medium-level jobs. 

If you’ll allow us to have one last say on size, it’s important to know the length of the hose before you buy. If you work on a remote site, for example, and will need to transport your air compressor to various locations, a long hose will hinder its portability. Shorter hoses are therefore better suited for anyone looking for ultimate portability in an air compressor.

PSI, CFM, and HP 

No, not that HP. Not after the author’s recent comments on gender identity. Rather than being shorthand for potions or spells, HP actually stands for horsepower, which refers to the amount of strength your portable air compressor will have. 

CFM is a measurement of Cubic Feet per Minute and it indicates how much air your portable compressor can inject into your deflated item per minute. The higher the volume of air that can be produced per minute, the more suitable your portable air compressor will be for larger jobs. 

PSI refers to the level of air pressure that can be generated by the tank and is measured in Pounds per Square Inch. A PSI of 90 would be found on domestic air compressors that are intended for light-duty use, whereas you’ll find closer to a 150 PSI on more powerful air compressors. 

How do you use it? 

If you’ve gone through all the trouble to read up on portable air compressors so you can make an informed decision about which is the best one for you, then you’re going to want to know how to use it. 

You should always consult the instructions your air compressor comes with when setting it up, as the process will vary between brands depending on what different functions they offer and their intended use. 

You may be required to complete a ‘break-in’ period before first using your portable air compressor by running it with the pressure valve open for a minimum of 15 minutes. This will help you make the most of your new compressor, but isn’t necessary for all models. 

They’re pretty simple to use, so even if you’re not an expert on cars you won’t have to call your garage the next time your tires need inflating. Simply switch your portable air compressor on and connect it to the air vent opening of the item you’d like to inflate. That’s it! 

The air will travel through the compressor hose and inflate your item. Turn off the portable air compressor once you’ve reached a level of inflation you’re happy with, and make sure the power source is also switched off. 

Noise levels 

Pumping air into a tyre or any deflated item is always going to come with a certain level of noise. Think about the last time you were in a room full of people frantically blowing up balloons before the start of a party, and then multiply it by 10.  

If you don’t want to be attracting stares for any reason other than how great your car looks while you’re inflating your tires, then look out for models with a lower decibel rating. These will perform much more quietly than air compressors with a high decibel rating, as it will indicate the amount of noise produced during use. 

Smaller air compressors that are designed for lighter use will make the least amount of noise, but they tend to be less powerful than other models which is also something to consider. 

Frequently Asked Questions

How do I find out what the correct PSI for my tires should be?

The optimal PSI for your vehicle’s tires can be found in your car’s user manual, or it’s easy enough to look up online, just remember to include the make and model of your car for accurate search results.

Is a digital pressure gauge better than a non-digital pressure gauge?

Digital pressure gauges tend to give a more accurate reading, although this will depend on the model. They are also easier to read as the PSI will be displayed in analogue form rather than trying to see where the arm lands on a manual pressure gauge. 

What happens if you overinflate your tires? 

Driving on overinflated tires means you could damage them. In the worst case scenario, your tire could even burst while you’re driving.

The most common consequences of overinflating your tires is that you’ll wear your tread down quicker and you’ll have less traction due to the increased air pressure distorting their shape.
