AstroAI Portable Air Compressor Tire Inflator (12V DC)
A compact 12V tire inflator that plugs into the cigarette-lighter socket, with a digital gauge, auto-shutoff and an LED light.
Quick verdict
Refills a low or freshly plugged tire in minutes without hunting for a gas-station pump, and the digital preset shuts off at your target PSI. AstroAI's best-selling inflator.
Who it's for
Everyone (low tire pressure is the most common tire issue), essential when paired with a plug kit.
Key features
- 12V digital inflator with auto-shutoff at preset PSI
What to know before you buy
- 12V socket-powered, so run the engine while inflating. Great for car/SUV tires and topping off, not a high-volume shop compressor.
