Obviously this is a brand that is both trusted and popular. We’re including a second Viair product on our list to give you two very different takes on the same product. This brand has an impressive list of features, and offers several types of tire inflators. This is one of their best models, and absolutely one that should be considered on your list. Looking for a quick fix that fills even large tires? Then you’re looking for the this particular portable air compressor.
Expand to see more
Alternative Power Source
This portable air compressor provides quick inflation on the go. Instead of plugging into an outlet, or your car’s cigarette lighter, this product is powered by your car’s battery. This means that you aren’t out of luck without an outlet, and it packs in more power than a cigarette lighter can provide.

Extended Reach
Struggling with short cords is the last thing you want to deal with in an emergency. Having a flat tire is bad enough without that added stress. Viair includes impressively long cords, including a 10ft power cord. Now that’s some serious length!

Cost and Value
While this compressor is on the expensive end it does come with some pretty neat features. On one hand connecting directly to the car battery provides extra power that gets the job done quickly. On the other, it definitely takes some setting up that other models don’t. The trade off, in the end, is up to you! If you’re looking for a powerful tire inflator with a powerful punch this might be the model you want.

Offers a better power source

Reaches up to 20 feet

Can full up to a 33" tire

Only 5.5 minutes of cool down time

Don’t end up like one of the many people who are out of luck when they end up with a flat on the road. Stay prepared in the face of what could otherwise be a disaster. Invest in your safety. You’ll be glad you did.


Criteria Used In Evaluation

Of The Best Tire Inflators in 2018


Safety Features

The number one piece of criteria to keep in mind when looking into air compressors is safety. Tire inflation devices can be an absolute lifesaver… in some cases literally. There are multiple ways in which a flat tire can turn a quiet drive into a risky situation. Depending on where you are, and what the visibility is like, it can be a nerve-wracking experience. Nobody wants to be stranded on the highway at night, for example, where cars are flying by and can hardly see you in the darkness. There are quite a few ways in which companies incorporate safety features into their air compressors, however! These companies recognize the risk that a flat tire can pose, and have tried to come up with ways to lower it.

One of how they do this is adding a flashlight to most models. This is not the case for all tire inflator models, however. It’s important to look for that feature specifically. The more settings you can find under the information for the flashlight, the better. Some of them come with a flashing mode, which can alert other drivers to your presence. In the “regular” mode, the light can be used to see what you’re doing as you re-inflate your flat tire. Regardless of what you’re using it for, it can be agreed that adding a bright light isn’t a bad idea in the least.

Another safety feature we look for is an automatic shut-off. This means that once the tire inflator is done filling the tire to the preset pressure, it automatically shuts itself off. This keeps the tire from overfilling and possibly blowing out. We also like to see overheating protection, which keeps the air compressor from getting too hot while it’s being used, or charged. These are all fantastic options that lend extra safety to anybody who uses them. We highly suggest looking for an air compressor that has most of these features, if not all of them if you can find one with safety features not mentioned here then even better! The more, the better.


You’re going to be traveling with your car tire inflator. The reason is right in the name of the product itself. You bought it to fill your tires when they’re low, or when you get a flat. So, naturally, it’s going to be with you at all times while you’re driving. Or, at least, it should be. We tried to find units that were relatively compact and had a lightweight design. Our search was mostly fruitful, and we found quite a few that were perfectly portable. The models that were not as portable happened to be larger units for filling larger tires. In that case, mobility becomes less of a concern, and more of a feature you have to trade-off.

Small air compressors can be stored away in your trunk without a whole lot of thought. We suggest tucking them into the same bin where you keep your emergency supplies. If you don’t have a bin with emergency supplies in it, get one. After you get one go ahead and put your tire inflator in it. It’s important always to be prepared! Some air compressors even come with a carrying case, which makes them vastly easier to keep organized. While a carrying case is nice, it isn’t truly necessary, so we wouldn’t use that as our rule of thumb when picking out a tire inflator. You can always put it in a storage bag yourself

Dual Charging Capabilities

Many models can charge in multiple different ways. This can be especially useful when you’re on the go all the time and haven’t charged your tire inflator in a while. Having an AC/DC charging capability, for example, means that you can easily use your cigarette lighter to charge the air compressor. This is only the case for some inflators, however, since some of them are simply too powerful for a cigarette lighter to handle. The last thing you want is a blown a fuse! These models are also able to plug into the wall. This is the suggested charging method and the one we generally recommend.

There are a few models that are only able to be used by being attached to the battery of the car. We included these because sometimes they’re the only style of air compressor that can handle larger jobs. This means trucks, SUVs, minivans, and other large vehicles. Smaller types of tire inflator simply don’t have the power to back themselves up. It’s a top priority to make sure that your tire inflator will work when you need it to. There’s no use in taking a chance, honestly. It’s better to sacrifice the inability to have a unit that’s already charged and ready to go if it means you can use it. After all, a charged air compressor doesn’t do you any good if it won’t fill your vehicle’s tires. In the case of large vehicles, dual-charging capabilities become pretty obsolete. If you have a sedan or another compact car, then go ahead and go crazy with extra charging options.


Simplicity can be a beautiful thing. This is especially true when it comes to working with automotive machines. You want to look at your air compressor and know, right away, which button does what. Having a simple, basic design can go a long way in helping you get back on the road that much quicker. That’s isn’t all there is to usability, however! We also take into account whether or not the product has a backlit screen, for example. This allows you to see what you’re doing even when it’s dark out. It also makes the numbers stand out and easier to read in general.

We also looked into how well the air compressor worked with the tires themselves. Some tire inflator products seemed to have nozzles that didn’t create quite the air-tight seal we want to see. Others had a short tip that made it difficult for some customers to attach it on their tire’s air valve. These are all seemingly small details, but once they’re put together, they paint a larger picture. Being stranded is stressful enough. You don’t need a poorly built machine that barely works, making it worse for you.

Extra Attachments

We’re huge fans of getting as much bang for our buck as we can. We’re pretty sure you are, too. There’s no harm in being frugal, and making sure you get the best deal. As the old saying goes, “‘A dollar saved is a dollar earned.” So, how does this relate to a tire inflator and the criteria used to determine our list? Easy! It turns out that air compressors can be used for a variety of different tasks. This means that they’re useful for far more than just fixing flats. Why buy such a useful tool and only use it for one of its capabilities? C’mon, be more imaginative than that!

Many of these air compressors come fully loaded with extra attachments. We’re a big fan of these because they open up so many doors for the customer (you!). Whether you’re at soccer practice with the kiddos or playing some Volleyball at the beach, you can easily save the day. Bike tire losing air? No problem. Whip out your air compressor, and fix it in a flash. Are you filling floaties? Stop using your lungs and losing your breath! Just use your air compressor, and enjoy the many uses you’ll find for it.


Frequently Asked Questions

About The Tire Inflator


Q: What’s the difference between AC and DC charging?

This is a great question and one that comes up often. You’ll notice that most tire inflator brands will say they have “AC/DC” charging. That’s great and all, but what does it mean, and how does it apply to you? The answer can get super technical, but we’re going to keep it on the simple side. After all, for this purpose, we don’t need to get into mathematics!

AC stands for alternating currents. It means that visually electricity travels like a wave. AC changes over time in an oscillating repetition. Up is a positive flow, and down represents the negative. DC, on the other hand, stands for direct current. It looks like a flat line and sends electricity right to where it needs to go.

AC provides more efficient energy than DC does, and at a higher level. This is why the cigarette lighter in your car runs off of direct current, but your home is operated off of alternating currents. Tire inflator brands that can do either are handy since you can charge them through your cigarette lighter if you need to. However, you can get a quicker charge from your home’s outlets if you’re able to charge ahead of time.

Q: What’s the difference between a “tire inflator” and an “air compressor”?

Is this a trick question? I kid, I kid! For those of you who aren’t automotive inclined, it can be confusing to see two seemingly different terms used in tandem. There is no difference between them. A car tire inflator is just another name for an air compressor! An air compressor is a slightly more broad term, however. As in: not all air compressors are tire inflators, but all tire inflators are air compressors.

But how can this be? Easy! There are air compressors out there that are used solely for smaller tasks than filling up a car’s tire. Think filling soccer balls, swimming floaties, balloons, and more. That’s pretty handy, though, because it means that you can use your car tire inflator for so much more! It’s always nice to have a tool on hand that can be put to work in multiple ways

Q: How do I properly use an air compressor?

Although there is a general “how-to,” we recommend always referencing the directions. Each tire inflator will come with its own set of rules, as well as a list of things to watch out for. They operate under different conditions, and in different ways, in accordance with their manufacturer. The directions they come with will tell you exactly what you need to know, and how to operate your air compressor. If you have any questions, you can always contact the seller! All of the products we’ve picked for this list have extremely high customer satisfaction ratings. These companies know how to take care of their customers, which is always a huge plus!

Q: If I get a flat while driving, what should I do?

This is one of those tactics that should be better explained to anybody who gets their license. Getting a flat while you’re driving can be a terrifying experience, especially if you aren’t prepared. The first step is to decelerate slowly. Do NOT slam on the brakes! This can cause your car to spin or slide out of control. You should also put on your hazard lights to alert the other drivers around you that something is wrong.

Once you’ve slowly decelerated, your next step is to pull off into the next safe area. If you’re on the highway, pull over to the right if you can, giving yourself plenty of room on the shoulder. When you’re not on the highway just pull over into the next parking lot you can, or even somebody’s driveway if there isn’t a safe parking lot nearby. The shoulder of the road works in a pinch but can be hazardous in some conditions. From there you can take out your tire inflator and get to work! You’ll be back on the road in no time.

Q: Will a tire inflator completely fix my flat?

This is entirely dependent on the reason for the flat. As we drive our tires lose pressure, which is why we have to inflate them now and again. However, most flats happen not because of this general pressure loss but because of a larger problem. If you leak your tire, you’re going to have to get it fixed. Sometimes a quick fix kit from your local hardware store will do the trick, but other times you may have to replace the whole tire.

We always recommend talking to your mechanic if you get a flat and seeing what they suggest. The tire inflator is a handy tool to get you going when you need it, but it isn’t a miracle cure. There may be a larger problem afoot, and if that’s the case you’ll want to get it fixed before it becomes a bigger problem!

Q: How powerful of an air compressor do I need?

The amount of power necessary to fill your tires depends on the type of car we’re talking about. Compact cars, smaller sedans, and other similar makes will be fine with a less powerful air compressor model. However, if you have a large vehicle, you’re going to need more power. The AC/DC convertible models are great for the first style of car. The larger vehicles will most likely require a model that attaches straight to your car’s battery. This is because they need the extra power that the car battery can provide since they’re filling much larger wheels. A more demanding job always means there’s more of a demand for power! You can check the details on the product’s description to figure out whether or not it can measure up. We also recommend always reading the reviews on a product to ensure that it really can do the job you need it for. Reviews are great for figuring out how a product is during actual use, and whether the manufacturer might have been stretching the truth a little.

Q: What does PSI stand for?

PSI stands for “Pressure per Square Inch.” This is a unit of measurement popular for measuring air, gases, or liquids. In this case, it is, of course, measuring the air pressure in your tire. It might not seem like a big deal, but it’s important to understand the basics behind these technical terms. Because of this, we get a lot of questions on units! There’s no shame in admitting that you have no idea what those little numbers mean. It’s better to learn so you can better understand the product you’re buying.

It means that you measure the pressure in the tire (which acts as a vacuum), relative to the pressure of the outside world. You want your tires to measure to a specific number, since being above that number can cause them to blow, and being below it will give you what is known as a flat. This is why that measurement is different between most cars. It’s also important to remember that air contracts and expands due to exposure to hot or cold conditions, respectively. This means that in the winter you may have to pump your tires up to a little more if it gets cold where you live.

There are two camps on this topic. A little research on your part might be required to figure out where you stand on the topic. Some people like to pump their tires up to a little more in the winter, and others swear against it. It’s just another tidbit to keep in mind when you’re buying a new tire inflator!

Decision Time

If you have read through the provided portable tire inflator reviews, you should have a better understanding of what you need to make a more informed purchase. It’s important to consider all of your needs ahead of time to truly pick the best tire inflator.

Do you prefer a higher PSI rating? Does it matter if the power comes from the battery versus the cigarette lighter? You may need a model that offers better nighttime visibility with an LED light or one with adapters. You may want one that is small and light and can be stored in small places in your vehicle.

With the best portable tire inflator, you should be able to avoid the trouble of having to change tires in the right circumstances. Even if you need a replacement, an inflator will help you get home safely and quickly.
