Incorporating its own smart pressure technology, the Jaco SmartPro portable tire inflator adds auto shutoff for setting a target PSI level and then pumping the tire exactly to that level. A 10-foot long power cord and 24-inch air hose make all four tires of a car, SUV or small truck accessible as power is drawn from a connection to any 12V outlet. Measuring the accuracy of inflation up to one PSI is a built-in digital air gauge that’s backlit for nighttime use and can measure up to a maximum of 100 PSI for bike tires and up to 45 PSI for auto tires. Two adapters are also included for use with sports balls, airbeds and other inflatables. A bright LED light that can double as a flashlight can also flash red and notify other drivers on the road of an emergency.

What to Look for in a Portable Tire Inflator

Type of adapter - Sure, you might need a portable tire inflator when you’re out stranded in the middle of nowhere—that’s the scenario we all fear. But what about if you’re closer to civilization? While many models can be powered off a car’s 12V adapter, you can buy tire inflators that also plug into a regular AC adapter as well. The versatility might be useful, depending on when you think you might need the device.

Maximum PSI - If you’re buying a portable tire inflator for a large truck, you may want to look into a larger model than if your vehicle is a small sports car or coupe. Differently sized vehicles have varying ideal PSIs, depending on how heavy they are, so you want to make sure you buy one that works with whatever the recommendation is for your specific vehicle.

Auto shut-off - When using a portable tire inflator, getting your tire filled with air as quickly as possible may be the only thing on your mind. However, you also need to pay attention to make sure you don’t overinflate your tire. Many models will automatically shut off when the desired PSI is reached, ensuring you don’t have to think about putting too much air into your tire.
