The AstroAI AIRUN H Tire Inflator is a 12V DC-powered portable air compressor that plugs into the car's cigarette lighter, fills a flat sedan tire from 0 to 35 PSI in about 5 minutes, and shuts off automatically once the target pressure is hit. The digital pressure gauge reads in PSI, BAR, KPA, and KG/CM², the LCD backlight makes night roadside use possible, and a built-in LED flashlight covers the rest. A 9.8-foot 12V cord reaches all four tires on most cars without unplugging, and the included nozzle adapters handle bicycles, motorcycles, sports balls, and small inflatables. Best fit: glovebox emergency kits, parents driving teen-driver cars, RV and trailer owners, and anyone who's ever waited 90 minutes for roadside assistance for a slow leak.

Frequently asked questions
How long does it take to fill a flat car tire?
From 0 to 35 PSI on a typical sedan tire is about 5 minutes. From a low 25 PSI top-up to 35 PSI is under 90 seconds.
Does it run off the car battery only?
Yes, it's 12V DC only. It plugs into the cigarette lighter or 12V outlet, and AstroAI recommends running the engine while inflating so you don't drain the battery.
Will it inflate motorcycle and bike tires?
Yes. Set the unit to BAR for road bikes (most need 80 to 130 PSI), and use the included Presta or Schrader nozzle adapters.
Is it loud?
Around 70 to 75 dB at the unit, similar to a vacuum cleaner. Most people don't run it for more than 5 minutes at a time.
