Small Air Compressor Advantages and Drawbacks

Best Portable Air Compressor ReviewsWith every machine, there are pros and cons, and a lot of things we must carefully consider before choosing a small air compressor. You don’t want to hand over hundreds of dollars only to find yourself in a situation where you don’t have the right tool for the job, especially if you’re working as a handyman or a contractor.

1. Advantages

The pros of having a portable version of anything lies in being able to take that machine anywhere you need it to be. Be it a roof, an apartment, the second story of a house, the attic, or somewhere high on a job site. Especially if you don’t have enough outlets or if the circuit breaker can’t handle the load that power tools put into it.

For all of these reasons, a portable air compressor would be an ideal solution. Many portable air compressors are made with smaller, more efficient motors so they run a much lower risk of tripping the breakers and leaving your job site without power.

Additionally, they far lighter to carry and transport so there are far fewer opportunities for injury while transporting your equipment. Portable air compressors more often than not, come with oil-less pumps meaning it is a much smaller hassle to maintain these machines.

Another advantage portable air compressors have is that they can save you from bad situations in roadside emergencies. There are even special lines dedicated to a battery or car engine powered compressor which you can use in a tight situation. Plus, because they are made to be very compact, storing them will never be an issue.

You can check our 12V air compressor reviews to learn more.

2. Drawbacks

The main disadvantages of portable air compressors are their size. Because they are portable they can only have a tank that isn’t that big. If you can’t put it on wheels and drag it with one hand, then it can’t be portable.

Because of the limit of the tank, you are limited to what kind of a job you can do. You can’t do anything that is very intensive like painting an entire car or house. You can’t do high-intensity work on your car like sanding for example.

Airflow can be another issue as well. Because while you may have the tank capacity, sometimes you will not have the adequate flow rate to run the air tool. This is because portable air compressors have smaller motors and can’t produce a lot of SCFM.

Basically, by getting a portable air compressor, you are limiting yourself to what tools you can use and what jobs you can perform with them. The portable air compressors are used more by hobbyists, DIY homeowners and construction professionals working on small projects because of these limits.

Small Air Compressor Buying Guide

Air compressors are a solid investment as they allow you to use air tools that consume less power in total. Portable air compressors give you that same benefit but also give you the freedom to use those same tools in hard to reach areas or places that you normally couldn’t access because of heavy tools or compressors.

They are an ideal solution for DIY projects around your home, fixing up your car or even construction projects where an electric tool just isn’t good enough. In this buying guide, we will clarify the portable air compressor specific point of view. In addition to that, you should check our air compressor reviews buying guide.

Who Should Buy A Portable Air Compressor?

Best Portable Air CompressorOnce you have come to the point of deciding that you want to have an air compressor, you have to make the important decision of getting a portable unit, or not. There are various types of jobs which are better suited for portable air compressors.

1.1 Road-side assistance

If you are a truck owner then you must know the rules about air pressure in your tires. Adjusting the air pressure in your tires for long trips on-road and off-road is not only smart but also prevents accidents from happening. Now imagine you are about to head off-road and you have forgotten to check your tires before leaving the city.

With a portable air compressor, this would not be an issue as you could easily inflate a flat tire in under 5 minutes. Or let’s say you get a flat tire and you are having trouble loosening up the lug nuts. A strong portable air compressor could save you time, energy and elbow grease getting that tire off of your car.

There are also other small air tools you could easily use to perform routine maintenance if your car happens to break down in the middle of the road or field. Some come with batteries, for others you need a generator or a car engine to power them, but they can always be useful. You can

1.2 For the DIY handyman and carpenter

Often, we aren’t able to perform certain repairs because the tools we use are too loud to use in the home or too heavy to lug up the roof. Air tools are lighter, use less power and can perform all of the jobs just as well as electric tools like small electric compressors can.

Another benefit if you are stapling or nailing something, you can have a portable air compressor with 2 people working at the same time. Thanks to bigger tank sizes you won’t even have to wait for recovery time. Instead of having a couple of people making all sorts of noise in your house, the compressor will be the only thing that’s loud while it’s filling the tank.

You can even have the option of putting the tank outside the window and use an air hose to make even less noise in the work area. When fixing your roof, you often have trouble getting the power to the tools. But with a portable air compressor, the power source is secure and you can get to work.

Also using a portable air compressor can mean fewer wires, extension cords and risks of overloading your circuit board.

If you already are or want to be a DIYer, our air impact wrench reviews, pneumatic grease gun reviews, and pneumatic die grinder reviews can also be useful.

1.3 The Hobbyists

Another popular usage for the portable air compressor is of course for various hobbies. Especially those that have anything to do with woodworking, metalwork or painting. Air tools cover all of these areas with a variety of choices.

With a small portable air compressor, you could cut, hammer, staple and paint a birdhouse if you want. Or give your kitchen a new coat of paint that’s equally distributed with your spray paint tool.

You could also just convert your compressor to an airbrush kit to give a little color and flair to your projects or even decorate your vehicles. Since it is portable, you can easily take your compact air compressor and air tools to a friend’s garage or workshop to work on a project together.

Wrap Up

Deciding on a portable air compressor is very similar to buying a new PC or a car. You have a growing sea of choices and it’s up to you to make the most of what the market has to offer you. Portable air compressors come in all shapes and sizes with varying performance ratings and noise. To make the smart choice you need to explore the market to find the best portable air compressor for yourself.

Always be mindful of what type of job you need to do with your air compressor and what tools you are going to need.
