12V Air Compressors Buyers Guide

There are many important aspects to look at when buying a 12 volt air pump. These include power, motor, and tank capacity, performance, and features. Listed below are more about these considerations to keep in mind.

Power, Motor, and Tank Capacity

There are many different power and motor sources a 12v air compressor can use. As listed above the power can come from an electric source, like a cigarette lighter port or a car battery. There are also other options. You could buy a gas-powered 12v air compressor. However, these compressors are very big and bulky and aren’t often as portable as an electric one. Gas compressors are also much louder than an electric one.

If you want something powerful for outside, a gas compressor would be best. However, if you’re working indoors you should use an electric powered one. This will prevent any gasoline fumes from entering the room and are easy to move around.

Also, the tank capacity is something you should look into. A large tank holds more air, but these tanks are often very expensive. A large tank though is good for a big project and when you need to use a lot of air.


To ensure your air compressor has a good performance, look at the CFM levels. You want a large CFM level amount if you plan to use many things at once with the 12v air compressor.

Horsepower is also important. This will show you how much work you can get out of your 12v air compressor. High horsepower means you can get more done.

The pressure level is also something to look at. If you plan to use your 12v air compressor for a small project, this won’t necessarily be important. But if you plan to use it for larger jobs and objects, you want to have a high pressure level.


There are many features that 12v air compressors can come with. Some to look for though is a LED light, cooling abilities, noise reduction, and if it’s portable.

An LED light built into the air compressor is good to have. This will help you see more clearly when you need to use it at night.

A cooling ability is also very important. 12v air compressors work hard, which means they generate a lot of heat. If they generate too much, it could end up blowing a fuse or destroying things. Having a cooling feature will help ensure it doesn’t overheat and ruin itself and the items it’s plugged into.

Noise reduction is a good feature to look for too. You don’t want to have a loud machine running, so a 12v air compressor that works hard and quietly is a good investment.

One of the most important features to look for in a 12v air compressor is portability. When you need to use a 12v air compressor you need to be able to carry it around easily. Having to carry a large and heavy machine isn’t helpful. So, be sure the air compressor you buy is easy to carry around when you need to use it. Otherwise, it could become a burden and hassle to use.

​Final Thoughts

Shopping for a 12v air compressor can be a daunting task. However, it doesn’t have to be anymore. This article included the 10 best 12v portable air compressors on the market.
