Portable Air Compressor Buying Guide

Some features and characteristics must be present in a portable air compressor to make it worthwhile. Here are some of the traits you should look for before buying:

The compressor should have sufficient runtime. Runtime is the most extended amount of time for which it can continuously pump air. If the compressor can only run for a short time, inflating a large item can become a tedious job.

The portable air compressor should be multi-functional. Multi-functionality means that it should be able to inflate a wide range of items safely. Usually, all of the portable air compressors have a PSI set feature, which helps it out in this task.

Make sure that the portable air compressor can run off of your car’s battery. This information is essential if you are buying it to inflate your car’s tires in an on-road emergency.

One of the most critical aspects of an air processor is its capability to pump air. You can judge this by seeing and comparing the HP or L/min of the compressor.

HP stands for the Horse Power of the motor, and L/min stands for Litre per minute, which denotes the amount of air it pumps per minute. Both of them are directly related. Therefore you can judge the compressor even if you know only one of them. 

The last thing to keep in mind is the dimensions, and the weight of the portable air compressor fits with your idea or portability or not. If you can, try to match the compressor’s size with the space you wish to keep it.

Keeping these points in mind, we can hop on to the review section to carefully choose some of the best portable air compressors from Amazon!

Frequently Asked Questions

How does an air compressor work?

Usually, the air compressors have a tank in which a piston forces the air. After that, the pressure is released through an opening using a pipe.

How does runtime affect compressor usage?

The runtime of a compressor is the period for which it can work continuously without any breaks. The runtime will essentially affect how long it takes you to inflate any item.

If you have a large item to inflate, it might take a long time if the compressor has a low runtime. You’ll need to switch it off in between, let it rest, and then continue again.

To compensate for this issue, some manufacturers pack in powerful motors coupled with large cylinders. These can pump out large amounts of air and inflate your item quickly.

Therefore when picking up a compressor, don’t worry if it has a low runtime; check its PSI and L/min to ensure the performance.

What is L/min?

L/min is the abbreviation for Litre per minute. This is a unit that denotes the amount of air that the compressor can pump in a minute. The higher the L/min, the faster the compressor can inflate things.

This mainly depends upon two things: the cylinder size and the piston speeds. The larger the cylinder, the higher is the air intake and pressurizing capacity of the compressor.

Can portable compressors be powered using a car battery?

Yes, it can be powered using a car battery, but there is a catch. Usually, the portable compressors run off 120 volts of power.

If your battery can provide that much power, then the compressor will run without any hiccups. Keep in mind that most compressors offer two methods of connection with the car battery.

The most popular method is through the cigarette lighter, and the second method is through cables. At times the cigarette lighter does not provide 120 volts of power, causing the compressor not to start.

In that case, you might try to connect directly with the car battery.

Can the portable compressors inflate a car tire?

This mainly depends upon the PSI of both the car tire and the compressor. Usually, small cars recommend a pressure of 30 – 35PSI in the tires. As the car/tires become more extensive, the recommended PSI increases as well.

The portable compressors can usually reach a maximum PSI of 57PSI. This means that if you have a small car, you should inflate its tire without any issue.

On the other hand, if the tire requires a higher PSI, the compressor might not inflate it properly. Running your car on an underinflated tire might cause hard to both the tire and the wheels.

Does the compressor need different attachments?

If you intend to inflate different household items with the compressor, you might need the air hose attachments. Each item has a unique airtight opening to facilitate inflation; if the compressor cannot adapt to it, it cannot inflate the object correctly. 

Conclusion

Portable inflators are a blessing in disguise. Whether you’re having a pool party or stuck in the middle of nowhere with a flat tire, portable compressors can save you within a few minutes.

Just go through our buyer’s guide, understand what you need, and pick the best-suited compressor out of the given bunch. You can’t go wrong with these selections!
