A portable tire inflator can be a handy tool to keep in your garage or vehicle for routine maintenance or taking care of emergency situations. They provide a quick and easy way to top up low tire pressure before you head off to work, school, or on a road trip as well as to fill spare tires in order to get to a repair shop. 

Most portable tire inflators can plug into your vehicle's 12V outlet (the "cigarette lighter" port), drawing power from the car or truck battery, but you can also find models that also run on cordless tool batteries and regular wall outlets for more options for power. The battery-operated models are great for anyone who already has that brand of tool and that kind of battery since they can seamlessly integrate into your workshop while 12V or 120V power models are better for anyone with less experience and skill who just want to keep their tires filled.

I've curated a list of the best portable tire inflators available from top brands like Craftsman, DeWalt, and Black+Decker and broke down their features to help you find the one that best fits your budget and needs.

What is the best portable tire inflator?

The Craftsman 120 air inflator is the best portable tire inflator that we recommend when comparing price, weight, dimensions, PSI, power source, usability, and more. Here's a look at how the best portable tire inflators measure up to each other:

Portable tire inflator	Price	Power	Max PSI
Craftsman 120 air inflator	$79	12V car adapter/120V AC outlet/20V battery	160
Skil Pwr Core tire inflator	$45	12V lithium ion battery	160
Black + Decker 20V Max cordless tire inflator	$67	12V outlet/120V outlet/20V battery	160
Husky 12V inflator	$40	12V outlet	130
DeWalt 20V Max tire inflator	$129	12V outlet/120V outlet/ 20V lithium ion battery	160

Which is the right portable tire inflator for you?

You should first identify what you want a tire inflator for. Do you want to keep one in your garage or workshop to top up low tires and do routine car maintenance? Or do you want to keep one in your vehicle as part of a roadside emergency kit? If you want to keep your tire inflator at home, you'll want to choose a model that is capable of multiple power sources so you can easily move around vehicles and your space. For roadside emergency use, you'll want a tire inflator that plugs into your car's 12V outlet for power so you can quickly fill low tires and spares to get yourself to a shop for repairs. 

Further, this buying tree can help you decide which portable tire inflator fits your needs:

Choose this portable tire inflator	If you want or are...
Craftsman 120 air inflator	Best overall
Skil Pwr Core tire inflator	Best portable tire inflator under$50
Black + Decker 20V Max cordless tire inflator	Best multi-purpose
Husky 12V inflator	Best 12 volt tire inflator
DeWalt 20V Max tire inflator	Best heavy duty

Once you identify where you want to keep your tire inflator (at home or in your vehicle), you should choose a model that has an appropriate power source, such as a 12V or 120V plug or port for a battery. You also want to choose a model that has an appropriate max PSI for your vehicle tires. You can find the max pressure for your wheels on the sidewall of the tire, usually by the branding.

How did we choose these tire inflators?

Aside from price, I chose tire inflators that were suited to a variety of different applications and skill levels. Push-button controls and easy-to-read screens make operation simple even for someone who has never used a tire inflator before, where more experienced users can appreciate multi-purpose attachments, multiple power sources, and quality of life features like cable management.

What is the difference between a tire inflator and an air compressor?

Size and max PSI are the main differences between the two tools. An air compressor is typically a large, metal tank with a motor and pressure valve attached to cold and release pressurized air; they're typically capable of much higher air pressure than a tire inflator, with max PSIs of 200 or more. Air compressors are also used for many more things than just inflating tires; you can purchase air-driven tools like sanders and torque wrenches or use your air compressor for high-powered cleaning of dust and debris in your workshop. Tire inflators tend to have lower max PSIs of around 150 or 160 for use with smaller tires and household things like air mattresses and sports equipment.

Does my car need to be running to use a tire inflator?

Not at all! If your tire inflator uses a 12V plug, it can draw power from the car battery without the vehicle needing to be on. In fact, you shouldn't have your car running while you're operating the tire inflator so you aren't exposed to exhaust fumes that can make you sick.

Are portable tire inflators worth it?

A portable tire inflator offers convenience in that you can keep your vehicle's tires properly inflated or repair them on the go. Considering some models start from under$50, it can actually save you money compared to having a towing company take your vehicle to a repair shop. 

Are there alternative tire inflators worth considering?

There are a lot of options out there if you're looking to keep a tire inflator in your vehicle for roadside emergencies or garage for regular maintenance. Here's a short list of alternative portable tire inflators that I thought were great choices:

Milwaukee M12 cordless compact inflator

$119 at Home Depot

Makita 12V CXT cordless inflator

$85 at Amazon

Ryobi One+ 18V dual function inflator

$70 at Home Depot
