What Is a Portable Air Tank?

One of the things you will enjoy after going through this review is being able to confidently pick a quality product from the list we have compiled for you. But before we walk you through the choices, you first need to grasp what an air tank is. Well, an air tank is an air storage compartment or air container that is usually used for storing compressed air under pressure. It is an essential vehicle accessory or tool that should always keep in your vehicle, workplace, and home. For tourists and regular travelers, you will fill the tank with compressed air and drop it in your trunk.

In addition to its motoring uses, you can use it to refill balloons and sports balls, use it for cleaning and assist with the tasks requiring pneumatic tools. Unlike an air compressor that may require high voltage and timing, an air tank is a better option because there is no room for those accessories. With that being said, we will dissect why you need a portable air container if you do not have one yet.

Emergencies: One of the reasons you need a portable air tank is to fill your tire back with air again in times of emergency. Indeed, your car tires can deflate in the middle of nowhere, exposing you to danger. Nevertheless, with an air tank, you will be able to reinflate it and continue with your journey.

It is safe: Some people would not consider the idea of getting an air tank because they are worried that the air container could explode, thus exposing then to immense danger. If you are one of those people, your concerns are not completely unfounded because we cannot rule that out completely. However, you can minimize the risk, by ensuring that the pressure relief valve is always intact. If there is any problem with it, you should replace it.

Portability: In truth, you can carry your air tank from one place to another without concerns that it will occupy a significant space in your vehicle. Because it is lighter than an air compressor, an air tank is more convenient to carry about. Therefore, if you any concerns about the size of an air tank in your trunk, you shouldn’t worry because it does not occupy significant space in your car, workplace, or home.

Affordability: Another reason why you need an air tank in your car, workplace, or home is that it is a budget-friendly air container. In short, most of the portable air containers on the market are very affordable, as you will get to find out later.

Convenience: Unlike an air compressor that needs a power source to operate, you do not need electricity to use air tanks. This explains why they are perfect for on-the-go use. Without a doubt, ease of use is one of the unique features that the portable air container brings to your car, trailers, bicycles, ATVs, home, workplace, etc. Therefore, you should get one for yourself.

How to Pick the Right Portable Air Tank

Moving on, we must look at some of the factors before buying an air tank.

Tank Size

One of the factors you must consider before going for the right air tank is the tank size. The tank size is a key factor because the tanks come in different sizes. What you wish to do with the tank and what you will need to inflate will determine the right size to go for.


In addition to tank size, you need to consider a good brand because some companies have gained acceptance and popularity in the industry by making premium products. With the name of a respected company on a product, prospective users see it as a positive sign of a high-quality product. The good thing is that all the brands in this review meet those criteria. Examples include Performance Tool, Craftsman, California Air Tools, ProForce, and Industrial Air, etc.


To buy the right air tank, ensure that your preferred product is constructed of high-quality material. A premium quality material is crucial in this regard because the material must be good enough to withstand the pressure that the tank is exposed to as well as resist rust. You should consider those made of steel, brass, or aluminum because they have been proven to be sturdy over time. If you do not buy air tanks of high quality, it could lead to leaks after a while and then end up in your dustbin.


Pound per square inch or pound-force per square inch is the unit of pressure for tanks. Put simply, the psi of a tank is the tank’s power. The pressure of a tank is directly related to speed because the higher the psi of your tank, the faster you will get your tire inflated. Hey, you should always look out for that!


Portability could be an issue in a situation where the tank is extremely heavy even if it is tagged “portable”. When the tank is filled with air, ensure that you can manage the weight of the tank. Moreover, it should have welded-on handles that facilitate easy lifting. You should always keep this in mind as well.


In truth, usage is critical because there are many factors you must consider. For instance, you have to consider if it is capable of heavy-duty performance and find out the type of piston. What’s more, you should be sure it has an accurate and reliable pressure gauge, look out for noiseless models, and ensure that the system is always cool. More importantly, you do not want to have to struggle to connect it with the hose whenever you wish to use it.

Best Portable Air Tank FAQ

Now, we will answer some of the questions you may have at the back of your mind.

How do you refill the air tank?

You do not need to get an expert to refill your air tank. To do that, you will have to attach the hose of an air compressor to your air tank and then use the air compressor to fill the tank. Make sure you monitor the pressure gauge to know when to turn off the compressor. When you have filled it to capacity you can then disconnect the hose.

How does an air tank differ from an air compressor?

Do not confuse an air tank with an air compressor because they are not the same thing. An air tank simply holds compressed air for future use while a compressor is needed to produce the compressed air to fill the tank (in the same way a compressor fills a tire). It is worth noting that an air tank is intended to take care of small tasks because it usually holds only a small volume of air. In contrast, an air compressor is made for heavier duty purposes.  

Is it possible that my air tank will explode in my trunk?

Motorists are embracing the practice of having air tanks in their trunks. Therefore, it is expected that one may wonder if they are likely to explode. The good news is that they often have pressure relief valves that vent the air if the pressure gets too high. So, realistically, you do not have to worry about explosions.

Which is the best for my car tires: A small compressor vs. small air tank?

More often than not, everyday people face this tricky choice, most especially if they already have air compressors. While an air tank has a limited air capacity, it is always advisable to opt for one because they are lightweight, quick, and convenient. Sure, an air compressor can also inflate your tires, but an air tank is better because of its guaranteed ease of use. Unlike the air tank, air compressors may require a power source to operate.


In wrapping up, we should reiterate that many people have found good reasons to replace their old air compressors with air tanks. Tanks are far more convenient to carry about so, as a regular traveler, you should opt for a tank. In the past, finding the right air tank was very difficult because finding reliable product reviews was not easy.

Given the time, effort, and resources that went into piecing together this informative guide, you do not have to go through the same hurdles to pick the air tank that meets your needs.
