Best Tire Inflators Ranked

26 portable tire inflators scored on price, airflow, features and warranty.

Last updated: October 22, 2026

A portable tire inflator is a small air compressor for topping up a soft tire, or getting a flat one back to a drivable pressure, without a trip to a gas station. They come in three kinds: cordless inflators with a battery that work anywhere, plug-in inflators that run from the car’s 12 V socket, and heavy-duty compressors that clamp to the battery for large truck, RV and off-road tires.

For a car, almost any inflator here will do the job; the differences are how long it takes, how loud it is and whether it stops by itself at the pressure you set. For big tires, or airing back up after deflating for sand or rocks, airflow and duty cycle matter much more, which is what the heavy-duty compressors are built for.
