The $32 Tire Inflator I Keep in the Trunk

A low‑tire light always seems to pop up when I’m already late. This AstroAI 12V tire inflator lives in my trunk so I can fix pressure wherever I park. It plugs into the car’s 12V outlet, has a long cord, and lets me preset the PSI with the M / + / – buttons. I hit start, and it shuts off automatically when it reaches the number I set. The screen is easy to read, and the built‑in light helps at night. It’s small enough for the glove box but strong enough for car tires, bike tires, and even balls with the extra nozzles.

Real example: on a cold morning my front tire was down to 24 PSI. I set the inflator to 36, started the engine, clipped it on, and it was done in a few minutes—no gas‑station hunt, no quarters. I’ve used it the same way on road trips and to top off the RV toad’s tires before leaving camp. Tip: run the car while inflating, set the target a bit higher than the current reading, and give the unit a short cool‑down after long fills. For the price, it’s the fastest win I’ve added to my roadside kit.
