Dead tire at midnight? The AstroAI L4 portable tire inflator gets you back on the road in minutes. With a powerful 150 PSI motor, cordless rechargeable battery, and built-in digital pressure gauge, this compact air compressor handles car tires, motorcycle tires, bicycle tires, and sports balls — all without fumbling with power cords or wall outlets.

Why Drivers Choose the AstroAI L4

Unlike bulky garage compressors that tether you to a power source, the L4 runs on a built-in rechargeable battery. Pull it from your trunk, set your target pressure on the LCD display, hit start, and the inflator auto-shuts off when your tire reaches the exact PSI you need. No over-inflation, no guesswork.

Frequently Asked Questions

Q: How long does the battery last?
A: The built-in lithium battery provides approximately 30 minutes of continuous inflation, enough for 4–6 car tires from flat to full on a single charge.

Q: Can it inflate SUV and truck tires?
A: Yes. The 150 PSI capacity covers standard SUV tires (typically 30–35 PSI) and light truck tires up to 44 PSI. For heavy-duty commercial truck tires above 80 PSI, consider a higher-PSI model.

Q: Does it auto-stop at the target pressure?
A: Yes. Set your desired PSI on the LCD display, and the inflator automatically shuts off when the tire reaches that pressure — no risk of over-inflation.

Q: How do I charge it?
A: Plug the included USB-C cable into any standard USB charger (5V/2A recommended). Full charge takes approximately 2–3 hours.
