Like other gallon portable air compressors, there are a lot of things to be considered when shopping for a 20-gallon air compressor. We've picked up the most important factor for consideration. Have a look, and don't forget to pay attention while purchasing.

Things To Consider While Buying The Best 20 Gallon Air Compressor

There are many factors to be considered when buying the best portable air compressor. Here are some important factors.

Power Source

The first and foremost important factor is a power source. The portable air compressors can be operated by either gasoline or electricity.

Electricity air compressor: It can be operated with the usual household voltage (110 – 120V). However, it requires 220 – 240 voltages when working with two horsepower motors. It is environmentally friendly, which is its highlighting feature. So, it doesn't emit fumes and runs quieter. This can be a great option for indoor applications.

A gas-powered air compressor, on the other hand, is used by builders and remodelers. This can be a perfect option for outdoor applications, which means commercial purposes, thanks to its high-power output and convenience. But it emits fumes and should be operated only in highly ventilated areas.

Maximum Pressure

The pressure level is another important feature. It should be considered on the air compressor. The pressure level is nothing but the amount of power it uses to refill the air in the compressor. It is measured by pounds per square inch (PSI). In general, the air compressors with high psi need rough air tanks and don't have powerful motors.

Duty Cycle

The duty cycle is measured in percentage. This term refers to how long the compressor can run before it takes a break to cool down and the time period of how long it takes for cooling down. In short, the amount of time it runs is a full cycle, including running and resting time.

Air Flow

Airflow, on the other hand, is a very crucial factor. It is measured by cubic feet per minute (CFM). It lets you know how much power it can deliver for tools or tires. Different brand air compressors have different cfm ratings. And various power tools require different cfm ratings.

For instance, the brand nailer requires 3 cfm, whereas HVLP spray requires 12 cfm. Hence, choose the cfm rating on the air compressor depending on the tools you use. We advise you to go with as high as possible since you can use it for any type of power tool.

Power Requirement

Power draw is another vital feature that should be considered while choosing the best portable air compressor. Many portable air compressors on the market use 12 volts for a cycle. You need to be very careful when buying an air compressor for your vehicles since they use their battery for working, especially for inflating tires. Make sure that you buy an air compressor that won't affect the vehicle's battery. Some air compressors use 120 watts, whereas some use up to 150 watts. These are the most common and the safest power watts for vehicles.

Motor Power

Obviously, the motor power is an important consideration, which is measured in horsepower (HP). If you want to operate many power tools, choosing the air compressor with 2 HP would be the best decision since it provides enough power to operate most tools.

Cord Length

When looking for a portable air compressor, it is important to consider the length of the cord. After connecting the portable air compressor and 12-volt power socket of your vehicle together, then, it needs to reach out to all the tires of the vehicle for filling the air. For this, you'll need a lengthy cord for ease of use. In general, some air compressors come up with a 15 feet long power cord, whereas others might have a 10 ft cord. We recommend you buy the portable air compressor with a 15 feet long power cord to use for any vehicle without any issues.

Tank Capacity

When it comes to the tank size, it is available in different gallons. It is usually measured in gallons. In general, the tank capacity of 0-6 gallons is the most common one. On the other hand, a small tank of 0 to 3 gallons is the best option for many domestic small applications. For large applications, it could not be the best choice since it wastes your energy and leads your compressor to wear and tear.

Hence, choosing the air compressor with at least 5-to-6-gallon tank capacity is an excellent option for larger applications or professional works. This gallon tank capacity works best for flat tires of your vehicle as it can inflate it in a single cycle, thereby saving your energy and time. This way, you can save your time on inflating tires in an emergency condition. This is because we advise you to consider the tank size and capacity of the portable air compressor before buying it.


The noise level would be another consideration. When it comes to the noise level, it varies from one to another portable air compressor. So, the best 20-gallon air compressor is no exception. The noise levels of the air compressor will depend on the operation and many other factors. The air compressors that have electric motors are generally quieter, whereas gas-powered ones are noisier than electric ones.

If you want the best 20-gallon air for your home purposes, it is better to go with a quieter portable air compressor, which means having an electricity-based air compressor would be better. If you are looking for a yard or workshop, or garage, choosing the model that sounds medium would be better.


The weight of the portable air compressor definitely matters while shopping. Although it doesn't impact the performance of the air compressor, it helps you make transport with ease. When it comes to the weight, starting from 20 pounds, a small portable air compressor. The larger compressor with a big tank would weigh around 80 pounds or more.

Though it comes with a lot of features, it might not be easy to move around, especially when purchasing vehicles. A small compressor with 20 pounds is easy to move and transport, which is also the best for inflating vehicles' tires to move from one to another tire. Plus, it also fits in your car trunk well.

Durability & Warranty

Warranty is another important factor since it ensures the reliability and durability of the portable air compressor. This is why checking the warranty is crucial while purchasing. Most units come with a one to a two-year warranty, whereas some have a lifetime warranty. So, ensure that you will buy an air compressor with quality and a longer warranty to avail yourself of the benefit for longer.


In terms of the price, it varies from one to another, depending on the features, quality, and brand. The following air portable compressors are affordable with many impressive features. They are worth buying for sure. So, choose the one that is suitable for your budget and needs.
