Just like no one should travel without a sound spare tire, people should consider making a portable air compressor an essential part of their Jeep car kit. Not only can they inflate your tire, but they may also help you fix punctures in an emergency (think off-road.) They can also help engage air-locking differentials and help you re-bead a tire that has come off the rim. As an added 4×4 away venture, they can even pump up your air mattress!

If you are seeking a reliable and portable air compressor, look no further. We have done the hard work for you and have given an in-depth look at these 7 best portable air compressors for Jeep in 2021. First, let’s get up to speed with some of the air compressor terminologies.

What to look for in an air Compressor for your Jeep

The Duty Cycle of your Compressor

All air compressors are subject to the heat created by pressurized air. The air that surrounds us is full of different molecules that release energy as heat when under compression.

An air compressor’s duty cycle tells you how long the unit can run in an hour without having to cool down. The manufacturer can either express this as time, such as 25 minutes or as a percentage, like 33 percent. A duty cycle of 25 minutes means that your air compressor can be run of 25 minutes out of 60 minutes and rest the remaining 35. A duty cycle of 33% means the compressor may run for a third of an hour (20 minutes) before it needs to be rested for the remainder of the hour.

The CFM Capacity

CFM is short for cubic feet per minute and measures how much air a portable compressor can send to a tire during inflation. Compressors with a higher CFM rating will inflate tires more quickly and draw more amperage from your vehicle.

This CFM level drops from a 0 PSI of a defeated tire increases as the filling tire offers more resistance. That is why the Viair 400P has a 2.30 CFM at 0 PSI but only 1.54 at 60 PSI. When it comes to average 4×4 tires, a twenty-minute duty cycle should be ample, unless you plan to share the compressor with more than one vehicle.

Customer/user reviews

Customers praised the Smittybilt 2781 5.65 as being fast and well constructed. Many reviewers remarked how fast this compressor is compared to other even more expensive options on the market.

What is an Automatic Air Compressor?

An automatic air compressor is handy because you can move between tires without switching your compressor on and off. You will also not have to switch off your pump to read your tire pressure accurately.

What pressure Should your Tires Be?

There are many different types of tires, and you would have to refer to your manufacturer to find your ideal tire pressure. This information is essential to know before attempting to use a portable air compressor. Also, the rule of thumb is:

Check your tire pressure when it is cold because the manufacturers base their recommended pressure on a cold tire PSI (or kPa) reading. The friction between the road and your tires builds up heat and heats the air inside your tires, thus building up a higher pressure.

Other Features to look out For in an Air Compressor for your Jeep

Air hose and power cord quality and length

The length of your power cord should reach from your battery safely outside your vehicle. Likewise, your hose length should be adequate to reach your tires with ease.

The air hose has to put up with a large amount of pressurized air and shouldn’t be flimsy. Your power cable should be robust enough to stand up to your compressor’s power load and have high-quality connections.

A legible and accurate gauge

Make sure you have a high-quality gauge with clearly marked gradations.

Duty cycle

The duty cycle refers to how long your compressor can operate in a one hour cycle without having to cool down. Make sure that your duty cycle length is long enough for the amount of inflation you might need to perform.

Output in CFM

CFM or cubic feet per second refers to how much air flow your compressor will deliver into your tire. Make sure that your CFM is at least 1.5 to 2 CFM to inflate your tires at a reasonable rate.

Thermal protection is essential to protect the motor of your compressor from becoming too hot and burning out.

Inflation speed dictates the speed of your tire inflation from flat or partially inflated.

Good quality storage bags/containers will protect your compressor and improve its longevity and portability.

The kind of chuck your compressor has can make your life easier. A chuck is the part of your compressor that attaches to your tire valve. The chuck comes in a twist or screw-on version or a press-on version.

The screw-on versions provide a tighter and more reliable seal, whereas the press on chucks is easy to connect and disconnect. The press-on chucks tend to suffer more from debris and sand and may not be ideal from extreme conditions.

12-volt outlet or direct battery clamps are options you might encounter when looking for the best air compressors for a Jeep. The 12-volt cigarette lighter socket may have the necessary voltage, but specific air compressors need at least 15 amps or 180 watts of power that a standard 12-volt plug can not supply.

If you are unsure of your outlet’s amp capacity, it may be stamped above or below the opening, or you might have to find it in your owner’s manual. Generally, the amps for a standard 12-volt socket is around 13 and will probably blow a fuse if you link it to your air compressor.

Decibels don’t seem like a critical feature when choosing your air compressor, but some of them can be uncomfortably loud. When you might have to kneel close by for several minutes at a time, you should look out for noise reduction features. Built-in heavy-duty sand bars help stabilize a unit and reduce noise, and rubberized feet also work to dampen sound.

Portability and size are a factor to take into account when buying an air compressor for your Jeep. Ensure the measurements fit your designated spot so that it does not become a headache when loading up for a long drive.

A decent warranty is a must when considering an air compressor considering most of them come with quite a hefty price tag. Warranty is an expression of faith by a manufacturer that the goods you buy are of high quality. You should expect a year’s warranty at least when you purchase your compressor.

Why Buy an Air Compressor for your Jeep?

Besides giving you the freedom to air-up and air-down to suit the climate and terrain, portable air compressors make your tires last longer (and we all know how expensive Jeep tires are to replace.)The biggest culprit behind the wear and tear of your tries are either inner air pressure that is too high or too low.

There is no monetary value that can be given to peace of mind. Especially if you travel out far in your Jeep into isolated areas, your portable air compressor is not only handy but will help you in emergencies. If you have the correct tire repair equipment, portable air compressors can help you repair your tires.

Conclusion

There are many portable air compressors on the market, and you need to know what you need before you commit to buy. Do your homework and know what specs will perfectly suit your needs.

Pay attention to manufacturer specs regarding cycle duty and use your compressor responsibly to increase its lifespan. Clean the filters often and make sure to clean off any terrain that made its way onto your unit. Hopefully, you may have already found the perfect fit in the above 7 of the best, and we wish you many happy trails.
