Tire inflators are small electrical pumps that use compressed air to inflate truck and car tires in a pinch. The best portable tire inflators can fit into the trunk or cargo area of your vehicle so you’ll have easy access to them during a roadside emergency. Because of their small size, they're best for quick pump-ups and emergencies only; inflating a completely flat tire to spec with one might take an hour—or more. If you’re looking for the best portable tire inflator on the market, check out our choices below.

Benefits of Portable Tire Inflators

  • Fill your tires anywhere. The most convenient way to put air into your vehicle's tires is by using a portable car tire inflator. It takes just a few minutes, and you don't have to go anywhere.
  • Safety. Fill your tire at home or on the shoulder instead of some sketchy filling station in an unfamiliar neighborhood. Plus, you can be confident you'll get air, versus some gas stations that have dilapidated pumps that are out of service or require quarters to operate.
  • Make your tires last longer. Overinflated or underinflated tires can cause a number of problems—or worse, accidents. To get the most life out of your tires, check your tire pressure every so often to make sure they are properly inflated.

Types of Portable Tire Inflators


You can fill up your tire using the cigarette lighter socket/12v power source in your vehicle. This is particularly useful if your car or truck has 12v DC outlets in more than one place. Some inflators also operate on 110v power (with an adapter), so you can plug them into an outside power source.


The best cordless inflator is typically powered by a lithium-ion battery. They are generally easy to use and are very portable. These inflators are handheld and provide a good amount of power. It's critical that you keep the battery charged, though, or else you may get stuck with a flat tire and a useless gadget.

Direct Power

These tire inflators attach directly to the battery for maximum power. However, a tire pump can suck the charge out of a stand-alone battery in about 20 minutes.

Top Brands

Portable Tire Inflator Pricing

  • $30-$40: There are many high-quality, small, and portable tire inflators in this price range, particularly if they are on sale. You don't need to spend a lot of money to find one that successfully inflates tires on passenger cars and SUVs.
  • $40-$100: Portable tire inflators in this price range typically have more features and may work faster than their less expensive counterparts.
  • Over $100: Tire inflators in this price range are generally more heavy-duty and can be used on vehicles such as RVs and trailers.

Key Features

Digital Gauges

The best tire inflators show tire pressure on an LCD screen, while the more traditional products will display the pressure with dial and needle gauges. A digital display will give you readings that are a bit more precise. Another added benefit is you will be able to read it in low light.

Automatic Shutoff

The auto-shutoff feature enables you to set the desired PSI, and the car tire inflator will run until it reaches the desired pressure. This is practical because the tire inflator will not overinflate the tire. You can walk away from the device as it does its job.

Other Considerations

  • Inflation Speed: Generally, you’ll want to fill your tire with air as quickly as you can. Heavy-duty models that connect to a battery's terminals typically inflate tires much faster than 12v or battery-powered models.
  • Extra Nozzle Attachments: The best tire air pump can serve multiple purposes. A model that comes with several attachments can be used on bicycle tires and sports equipment as well as car tires. 
  • Portability: The best handheld air compressors are small and lightweight. They generally weigh between two and six pounds; some smaller ones weigh less than one pound.
  • Hose / Cord Length: The longer the cord and air hose are, the easier it will be for you to reach all four tires on your vehicle. The best tire inflator will usually have a hose that is 18 to 26 inches long and a power cord that is at least eight feet long.
  • Cord Storage: Some models have a storage cavity that allows you to coil up the cord into a small compartment.
  • Built-in Lights: This option is particularly beneficial in roadside emergencies. If it's dark outside, a tire inflator with a built-in flashlight will illuminate the tire and can also alert passing motorists.
  • Noise: Portable inflators are notoriously loud, depending on their size and purpose. That's why it's best to get one you can walk away from while it's filling the tire.
  • Duty Cycle: This is the amount of time the inflator needs to cool down before you can use it again. Inflators with short duty cycles are preferable because they don't require as much time to cool off. 

Best Portable Tire Inflator Reviews & Recommendations 2021

Best Overall
JACO SmartPro Digital Tire Inflator

This JACO inflator features a heavy-duty 24-inch air hose with a brass connector for durability and can pump up to 100psi at 24 liters per minute. It also has a 10-foot cord that plugs into any 12v DC outlet on your vehicle, and a digital display with backlight for nighttime use. The built-in LED light features four settings: off, flashlight, flashing red, and emergency SOS. Best of all, it comes with a limited lifetime warranty.

We like the JACO because it's a well-known, respected brand. It isn't the most affordable of the bunch—and that's a good thing. Pay a bit more money, you'll get a lot more confidence.

Best Value
VacLife Air Compressor Tire Inflator

The VacLife Tire Inflator is an affordable, easy-to-carry portable tire inflator, and it’s great to have on hand in case of a flat. This air compressor/tire inflator works quickly, and it can inflate a car tire in just seconds. It plugs into the 12-volt outlet in your car, and with the flip of a switch, this small device will get the job done. 

There are four nozzles, so you can achieve the right fit for your car tires. It includes an auto shut-off feature, which automatically turns the device off once your tire is at the desired pressure level. This prevents issues like over-inflation and low tire pressure. 

And when you’re using this tire inflator on the go, you’ll appreicated the LED light that provides brightness at night and the 13-foot power cable that makes it easy to move around your vehicle. 

Honorable Mention
Gerchway Tire Inflator

We've used this one, and we liked it more than others we tested. (Read our hands-on review of this inflator here.) The Gerchway tire inflator is reasonably priced, lightweight, and easy to use. It has touchscreen operation which means there are no moving external switches to get stuck or rusted. It also has a built-in digital gauge and automatic shutoff. Power comes from a 12v cord that plugs into your vehicle’s outlet, and the cord is long enough to easily reach all the tires on your vehicle without much trouble. The inflator comes with adapters for other types of inflatables such as balls or air mattresses, and also includes a nice zippered bag to store it all in, so you can easily carry it in your trunk or storage compartment.

Honorable Mention
Avid Power Tire Inflator Air Compressor

This tire inflator comes with a rechargeable battery and a USB plug for charging devices. It also comes with a 12v cigarette lighter plug. Having two ways to power this inflator lets you use it for a variety of uses; it also comes with several inflating needles for inflatable toys and sports equipment. It has four pressure measurement units: PSI, KPA, BAR, and KG/CM2. This inflator is lightweight and comes with a carrying bag for easy transport. 

Honorable Mention
Ryobi 18V ONE+ Cordless Power Inflator for Tires

The Ryobi tire inflator is cordless and runs on Ryobi's One+ 18-volt lithium-ion battery. That battery is not included in this package, hence the low price. Still, if you're a Ryobi devotee, this inflator is a marvelous value. It's small and features an ergonomic pistol grip handle, two high-pressure nozzles, a sports equipment needle, and an onboard pressure gauge. The inflator is lightweight, very portable, and requires little storage space. The battery charge lasts long enough to inflate several tires in one sitting and can raise an average car passenger tire 5psi in 30 seconds. It also lets you see the pressure as you work. Interestingly and disappointingly, the trigger doesn't lock, so you have to hold it while it inflates.

Honorable Mention
Milwaukee M12 Compact Inflator

At four pounds, you can easily carry this portable compressor to the spot where you need it. It’s also battery-powered, so there’s no need to find a power source. On the face of the unit is a digital display screen and several buttons for operation. It will fill a car tire to between 28 and 35 PSI in under one minute. If you need 30 to 45 PSI, then it’ll take under four minutes. 

Since this compressor is battery powered it’s useful for most inflation jobs. It’s compact size also makes it easy to carry. The display is large, which makes it simple to read the pressure and work the buttons. There are several safety features, including protection from overfilling and over temperature. 

Unfortunately, this compressor doesn’t come with a battery charger, so you need to buy one separately. What’s worse is it doesn’t come with the battery, so you need to buy one of those too. It’s also not as compact as other portable compressors.


  • Even the best portable tire inflator should be stored properly and kept in a dry environment. Since it is an electrical device, moisture can damage it. You’ll want to keep it as rust-free as possible.
  • Carefully watch the gauges as you fill your tire. Unless the machine has an automatic shutoff feature, it's up to you to make sure to turn it off after it reaches the desired PSI.
  • Do not underinflate your tire. This may lead to dry rot on the rubber on the sidewall of the tire. This damage will eventually lead to tire failure, which can be dangerous. 
  • Tires that are underinflated also use more energy, draining your car’s fuel faster than properly inflated tires. In addition, underinflated tires can contribute to handling issues, which may lead to an accident. 
  • Check your tire pressure about once a month. Tires lose air for several reasons, including a drop in air temperature or normal seepage. It can be a gradual loss, and you may not even realize it.
  • Typically, portable tire inflators shouldn't be used for more than 10 to 15 minutes at a time. To avoid overheating, let them cool for 10 to 30 minutes after each use.


Q: What does PSI mean? 

PSI stands for pounds per square inch, and it's used to measure tire pressure. For example, 300 PSI means 300 pounds per square inch. In air compressors, a PSI gauge tells you how much pressure is in the tire.

Q: How do I determine maximum PSI? 

Look at the tire’s sidewall. Tire dealerships also have charts to give you PSI information that take into account factors such as the amount of weight your car or truck is carrying.

Q: How do I check my tire’s air pressure? 

Remove the valve stem caps. When the tires are cold, meaning the vehicle hasn’t been driven in several hours, push the compressor's hose fitting onto the valve stem and check the gauge. Fill the tires to the recommended pressure. Reinstall the valve stem caps.

Q: How do I inflate my tires with a portable tire inflator?

Remove the valve stem caps. Push the compressor's hose fitting onto the valve stem and check the gauge. Fill the tires to the recommended pressure (it's best to do this when the tires are cold). Reinstall the valve stem caps.

Final Thoughts

Our pick for the best portable tire inflator is the JACO SmartPro Digital Tire Inflator Pump. It’s fast and efficient inflator from a trusted outdoor brand. Moreover, it falls in the sweet spot of price points—not pricy, but not "too cheap" either. 

For something with even better value, consider the VacLife Air Compressor Tire Inflator. We actually purchased this model ourselves a while back, and it's been very reliable.
