In this guide,

  • We break down exactly what to look for in a portable air compressor,
  • break down everything air compressors can do that you probably didn’t know about,
  • help you learn how to use air compressors for the first time, and
  • present to you our top recommendations based on our research.

Let’s get started!

Understanding What Portable Air Compressors Are and Why They Are Great Tools-

Simplified an air compressor is a tool that takes in air or energy into a tank that stores the energy and then creates enough pressure to release the air at much higher power.

For a full breakdown of exactly how an air compressor works, we suggest checking out this wiki page for the full summary of the science.

Even a relatively small air compressor can create enough pressure/energy to take out the tedious and strenuous labor of pumping a tire manually.

Whether that machine is going to predominantly stay in your garage, carried around in your car or truck, or even stored on an RV, there are plenty of options that are not only affordable but versatile.

Understanding the power capacity, size, and your needs for an air compressor will help in your decision-making process.

The rest of this guide is designed to figure out your needs so that you can purchase the perfect portable air compressor for you.

Making Life Easier: The Benefits of An Auto Tire Air Compressor

Many people associate air compressors with either industrial work or other only for blowing up tires.

What a majority of people don’t realize is how versatile a portable air compressor can be. With all the major benefits of owning an air compressor, it easily becomes one of the most valuable tools you own at the house.

1) Blowing Up Tires– We know this seems like the most obvious benefit of an air compressor but there is actually a lot more you can do with tires than you could with hand pumps or going to the gas station.

With a tire inflator, you have more power which gives you the option to air up tires that have become unbeaded.

A good portable air compressor will pump not only car tires but motorcycle tires, bicycle tires, and tires for tools like dollies.

2) The Air Is Free and Can Be Used for Multiple Purposes– Your portable air compressor’s pressurized air can be used for multiple different tasks around the house.

With the right air nozzle, the air can be used anywhere from woodworking projects to clearing and cleaning out pool piping for the winter.

3) Powering Power Tools– Air compressors can be used to help power tools around your house.

Some of the more popular tools that use air compressors are nail guns, drills, sanders, wrenches, and ratchets.

Air compressed power tools are far more powerful, require less physical exertion by the user, and are far more effective than the same tools without being powered by air compressors.

4.) Paint Sprayers– Using an air compressor with a paint sprayer not only increases the power of the paint sprayer but it also gives a more even coat of paint. Almost all car paint jobs use an air pressured paint sprayer to ensure an even coat without the paint running.

If you want to find out what air compressor paint sprayers I recommend, just check out my air compressor paint sprayer guide.

5.) Portable Air Compressors are Portable– Another simple and obvious benefit but portable air compressors fit almost anywhere. You can take your air compressor with you in the car, place it in your garage or shed, or easily lend to friends due to its portability.

Portable Air Compressors for Tire Inflation: How They Save You Money

According to the most recent study done by the government at fueleconomy.gov, having properly inflated tires is a big money saver.

The review is here , but a summary of the research shows that under-inflated tires hurt gas mileage.

Roughly speaking, for every one PSI your tires average under the recommended level, you lose .2% on your gas mileage.

While this seems like a small number that averages out to .2 cents per gallon for every PSI, you are low.

That means if you are 5 PSI levels low you could be losing up to .10 cents a gallon in gas.

Having your tires at the proper PSI levels at all times also extends the life of your tires. Under or over inflated tires shorten the lifespan of your tires by putting unnecessary strain on your tires. Under-inflated tires are also more likely to lead to flats or replacements.

It is simple to see having a quick and easy way to check and inflate your tires to the proper levels will keep you safer, save you money immediately with gas milelage, and save you money in the long run by extending your tires life.

Why should you trust our recommendations?

We have spent hours researching, talking to industry professionals, and testing portable air compressors to provide you with the most accurate and up to date information.

Through our process, we break down every aspect of what makes a great portable air compressor to give you the best recommendations possible.

Our hours of research mean you can purchase a portable air compressor stress-free knowing you are buying a portable air compressor that is not only right for you but the best value for your needs.

Our Complete Car Air Pressure Sizing Guide (Size matters, get it right)

It’s true that you could inflate your car tires with an air compressor of any size, but the best car air compressor for tires will be powerful enough so that the process is quick and convenient.

After all, if you were inflating a set of completely deflated tires that had been in storage, you wouldn’t want to wait around for an hour or more while your tiny electric compressor trickles air into your tires.

For speedy operation, tire inflation should be performed with a unit that produces at least 1 – 2 CFM.

CFM is a measurement of the volume of air that can be moved by a compressor. Many solutions, such as an electronic cigarette lighter compressors produce far less than 1 CFM, and are generally only good for emergency inflation when you have no other options.

The most efficient car air compressor will be coupled with a tank to store pressurized air. A powerful unit with a suitably sized storage tank will pump high-pressure air continuously, to quickly inflate car tires, truck tires, or even bicycle tires.

In all of our reviews and recommendations, we have taken the time to measure the CFM and compare it to the size and portability of the tank. We have carefully analyzed each portable air compressor and give you our best recommendation for every possible one of your needs.

Two Popular Compressors for Tire Inflation

Of course with all of this information, it can still be difficult to determine the best air compressor for tires, either car or bike tires. As with many air compressor scenarios, the ‘best’ really does depend on your individual needs. Take a look at these two options which represent different segments of the market.

The first is suitable for cars, light trucks (SUV’s), bicycles, and low-intensity DIY duties.

The second is more compact and is perfect for inflating tires, but will struggle with other larger tasks.

Porter Cable PCFP02003

This portable Porter Cable compressor was reviewed in full right here on Power Tools Ninja.

We found the compressor to be capable of a variety of air tool related tasks, but it was especially impressive when it came to inflating tires. Unlike some smaller compressors, the Porter Cable was able to run near continuously when inflating vehicle tires. This is helped by the 3.5 gallon tank size and 2.0 CFM rating (see more about CFM at this link).

When topping up tires you won’t need to wait for the compressor to kick in and restore air, however if you’re inflating full flats you could wait a few minutes between each tire while the tank gets back up to pressure.

For bicycle tires, motorcycle tires, and inflating things like boats and water-toys, the Porter Cable does a phenomenal job. The fact that it can be had at a number of online retailers for under $100 makes it one of the best air compressors for tires.

Here’s the link to Amazon for easy reference and to check the latest price.

DeWalt D55140

If you don’t need the flexibility of running other air tools, the D55140 is an excellent choice. For inflating tires it performs well with just under 1 CFM of air flow, and a small 1 gallon tank. Due to the smaller tank this compressor will cycle continuously while you’re inflating tires, but the good news is that it is able to keep up. This means you won’t wait around for the compressor to rebuild pressure in the tank.

The key advantage of this DeWalt compressor is that it’s one of the most portable tank air compressors on the market. It weighs in at only 24 pounds, and it’s only 9 inches high. It can be run off an inverter, and draws 2.6 amp in operation. In addition, it’s quiet operation (only 69 db) makes it an ideal choice for people who are put off by the loud noise that other similar air compressors might produce.

This makes it the perfect road companion, and it would be well suited to sit in a vehicle, truck, or even an RV motor home. Needless to say, just like the Porter Cable, this compressor has enough power to inflate bicycle tires, motorcycle tires, or anything else around the home that you can think of.

Best 12V Air Compressors

As already mentioned, the cheap alternative to the bigger air compressors would be the small, portable 12V air compressors which are designed to exclusively pump air not only into a car, bike, motorcycle, and even truck tires but also into inflatable toys, balls etc.

These smaller compressors allow you to hook them up to power tools such as ratchets, paint sprayers, and nail guns and still give you the freedom to move around for your projects. The smaller tanks also are designed to cycle quicker so you can continually work without waiting for the tank to fill.

Below, I present to you for easy reference, a summary table where you can see a list of my top eight (8) recommendations for 12V portable air compressors and their main features.

OPTION 1:  AUDEW Portable Air Compressor (Our Best Overall)

Audew Portable Air Compressor Pump Option 1We do like the AUDEW Portable Air Compressor quite a bit. We rank it our best overall portable air compressor because it tests like other high performing air compressors but does not cost the same. What you save in your wallet was not sacrificed in  .

One of the reasons for this is because it comes with an auto-shutoff feature. Simply set the desired PSI and let the pump do its thing. Once the desired PSI has been reached, the pump will shut off to prevent the over inflation and popping of your tires or whatever else you are inflating.

AUDEW is charged by a cigarette lighter just like the air compressor above but adds convenience with its air hose. The AUDEW Portable Air Compressor comes with a 10-foot-long air hose, which means you can easily fill the rear and front tires of your car. Speaking of your vehicle, the AUDEW Portable Air Compressor has more than enough juice to fill up RV tires, cars, bikes, motorcycles, ATVs, trucks, and sports equipment too.

The AUDEW Portable Air Compressor is also very small and lightweight, making it a highly portable air compressor that you can take with you no matter where you go. Our test proved that it ran quietly compared to other portable air hoses.

The AUDEW Portable Air Compressor is so light and compact you can put it in your trunk without taking up a ton of space.  This pump also comes with long-lasting LED lights, so you can easily use the AUDEW Portable Air Compressor during the night without being totally in the dark.

There is also a one-year warranty on this device. Consequently, you’ll be able to trust that you’ll be taken care of if there should be any problems during normal use within the first year.


OPTION 2: LifeLine AAA 300 PSI 12 Volt DC Air Compressor (Our Best Value) 

LifeLine AAA 300 PSI 12 Volt DC Portable Air Compressor Option2One of the more popular DC 12V tire air compressor among consumers, the LifeLine AAA 300 PSI 12 Volt DC Air Compressor represents true value for your money. Easily our best value pick of the bunch if you are looking for a wallet-friendly option that still performs well this is the air compressor for you.

It is equipped with a quick connect air hose, it goes up to 300 PSI.

The cord that goes to the cigarette lighter from the compressor is 10 feet, while the part of the hose that goes from the unit to the valve stem is 18 inches.

It is recommended that you use a15A rated cigarette lighter to ensure proper functionality even though the unit itself draws 10A. When you purchase from Amazon the seller offers a 1-year warranty that will give you ease of mind on your purchase.

According to the manual, it takes about 8 minutes to go from 0 to 35 PSI. Our actual test took about 2 minutes to go from 33 PSI to 40 and less than 5 minutes to go from 20 PSI to 44.

The only real drawback is that the unit as a whole is a bit loud and jerky. This can be expected when it is drawing power from a cigarette lighter and you must keep in mind the price point when you hear the noise.

As long as people realize that this little compressor is meant only for occasional use and good only for filling up rather than going from flat to full, then it’s the best value for your money.

OPTION 3: VIAIR 85P Portable Air Compressor (Our Best Quality)

VIAIR 85P Portable Air Compressor Option 3The most popular mid-tier priced air compressor, the VIAIR 85P performs well over its price point. There is a reason this is Amazon’s best seller online.

This unit operates up to 60 PSI maximum working pressure, draws powers from the 12V cigarette lighter outlet in your car, is capable of inflating up to 31-inch tires and comes with a large, easy to read pressure gauge.

The VIAIR 85p has a built-in LED which comes in handy with situations where the surrounding light is low.

The test shows the compressor is fast (it took him less than 30 seconds to go from 32 to 35 PSI) and is quiet. If you are worried about noise this a much better option than the LifeLine.

One great aspect that puts this tool ahead of its competition is the top quality of its construction: Other than the handle which is plastic, the rest of it is made of metal. This fact alone makes it very reliable and durable and contributes to the low noise production.

Although VIAIR is a US corporation, the unit is made in China and imported to the USA.

One other thing that owners should be aware of, the compressor is oil-less, so it generates a lot of heat inside. During testing and use the metal became very hot on the inside and should not be touched with your bare hands.

Best Tire Inflator Recommendations: No More Guesswork for You

Now, I will give you my top six (6) recommendations for the best tire inflator models.

Tire inflators are tools that are either hooked up with the air compressor and their job is to provide a readout (digital or analog) of the pressure inside your tires and also control the flow of air, or they are small air compressors themselves.

Here’s a summary table for my top recommendations, that includes the main features of each model, for your easy reference. As in table above for the 12V air compressors, you can use the links to go to a more detailed description further down, or go directly to Amazon.

Having the pump powered by batteries gives allows this portable air compressor to be well more portable. They also replaced the hose with a 21” stainless steel braided one.

Its operating pressure is 3 – 175 PSI and one powerful feature is that it comes with a two-position lever, allowing the user to not only inflate but deflate at will, thus making more precision fills. In our tests, the digital gauge was accurate up to .01 PSI making it one of the most accurate gauges that we tested.

Coming in at under 7 inches in length and at only 15 ounces, it is one of the most portable and convenient small air compressors that you can get your hands on at this time. It also comes with various nozzles so you can fill up things like balls and rafts.

Through our testing, we were able to get a PSI max output of 100 which is right in line with what the manufacturer claims as maximum output. It was able to bring a car tire to 35 PSI in roughly 7 minutes. Some of the other portable air compressors will fill it faster but are larger in size.

The Best Accessories to use with an Air Compressor for Tires-

Accessories to your portable air pumps can help diversify its usages and improve upon the quality of your air compressor setup.

Having high-quality accessories will not only increase the effectiveness of your air compressor but will also protect your investment.

Here are some of the top accessories to take your portable air compressor game to the next level.

Quality High-Pressure Hose

There are many reasons to buy a new pressure hose for your air compressor. You might want another hose if your old hose has got a hole or corroded, you want a long or shorter hose, or you want something of higher quality than the stock hose that comes with your air compressor. Whatever the reason there are a couple of things to keep in and mind and look for in a hose.

 There are three things to keep in mind when purchasing a new hose for your air compressor- Diameter of the hose, length of the hose, and type of material the hose uses.

 The diameter of the hose is essential for two reasons. The width of the hose needs to be able to connect to the output valve properly on your air compressor, and a hose to big or too small will not work.

 Secondly the wider the tube, the more air needed to fill it. If your air compressor’s output is on the lower PSI level, a tighter tube can increase your air compressors performance. However, if you have a powerful air compressor but small hose you restricting the overall output and wasting your compressors power.

 The hose that carries the air from your compressor to the tire should be a high-pressure product (up to 250 PSI) and should be made by a reputable manufacturer. A 3/8 inch hose is suitable for inflating tires, and 25ft is the perfect length for getting around a vehicle to service all four tires. Goodyear, Amflo, and Campbell Hausfeld are all leading manufacturers who produce high-quality hoses for as little as $20.

Best Portable Air Pump For Car Tires with Gauge

The other all-important accessory is the inflator that you will use. Simply connecting the right inflator will put air in your tires, but how will you know once you’ve achieved optimum pressure? Bicycles, cars, and trucks all require different PSI in the tires to achieve manufacturer safety and performance ratings.

A tire inflator with a gauge will make sure that you’re always on the mark.

After researching many different models and digital gauges, we recommend a digital gauge.

There are two types of gauges analog and digital. Both are effective, although a digital gauge is much easier to read and through our testing were just as accurate as analog gauges.

Gauges can indicate pressure in BAR, PSI, and some will display a KG reading also. The most common measurement is PSI.

Digital Tire Gauge

Another handy tool that is is especially useful if you have the bigger compressor and you don’t have a tire inflator equipped with the pressure readout display is a digital tire gauge. Insert the end of the tool in the valve stem, and you can read the display.

The best tire gauge that we currently recommend is the TEKTON 5941 Digital Tire Gauge.
