    What to Consider When Buying Portable Tire Inflators

    Portable tire inflators can vary widely in their size, power, and portability. To help you pinpoint the best option for your vehicle and needs, make sure to keep these key details in mind as you shop. 

    Types of Portable Tire Inflators

    12-Volt Plug/110 Volt

    The best portable car tire inflators and portable truck tire inflators can be used on the road. During an emergency, you can supply some models with power by plugging them into the cigarette lighter socket/12-volt power source in your vehicle. This is particularly useful if your car or truck has 12-volt DC outlets in more than one place. Some inflators also operate on 110-volt power so you can plug them into an outlet in your garage or 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 or else you may get stuck with a flat tire.

    Direct Power

    These tire inflators clamp on directly to the battery for maximum power so you don’t have to have the vehicle running. However, a tire pump can suck the charge out of a stand-alone battery in about 20 minutes. 

    Portable Tire Inflator Key Features

    Digital Gauges

    The best digital tire inflators will display the inflated pressure on the gauges. Some newer models will show this information 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 if the screen is backlit.

    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 a practical feature because the tire inflator will not over inflate the tire. You can walk away from the device as it does its job and not worry about the tire bursting.


    You can find small, ready-for-the-road portable tire inflators at just about every price point. Budget-friendly models with streamlined features and simple functionality are $25 to $50. If you spend $55 to $100, you’ll find more advanced options with increasingly more features. And if you’re looking for a hefty, premium air compressor that’s portable yet larger and more versatile, you can spend $100 or more.
