Product Overview

The AC-1166 is a high-performance DC 12V in-car tire inflator featuring a bright digital display for real-time pressure monitoring. Powered directly by your vehicle's 12V accessory port, it requires no batteries to charge — it is always ready when you need it. With a 22mm cylinder diameter and 0-150 PSI pressure range, the AC-1166 can inflate a standard 195/65/R15 passenger tire from flat to full in just 5 to 6.5 minutes. The large backlit LCD screen clearly shows current pressure, preset target, and unit selection (PSI/BAR/KPA/Kg/cm squared), making it incredibly easy to use even in low-light conditions. The auto-stop function lets you set your desired pressure and walk away — the unit automatically shuts off when the target is reached, preventing over-inflation. An integrated LED work light illuminates the valve area for nighttime roadside emergencies. The generous power cord reaches all four tires without repositioning, and the included accessory kit handles sports balls, air mattresses, and bicycle tires with equal ease. Built for the serious driver who values speed and precision over portability.
