The AC-1966 is a compact cordless tire inflator powered by a 7.4V dual 2000mAh lithium battery, designed for occasional use and emergency preparedness. The digital display shows real-time pressure in PSI, BAR, KPA, and Kg/cm squared, making it easy to monitor inflation progress. With a 15mm cylinder diameter and lightweight construction, this model prioritizes portability and simplicity. It fully inflates a standard 195/65/R15 passenger tire in approximately 12 minutes — not the fastest, but consistently reliable for topping off low tires or handling a roadside flat. One charge provides up to 1.5 complete tire inflations. The compact cylindrical body fits easily in a door pocket or under-seat storage compartment. A built-in LED light aids nighttime operation, while the auto-stop function prevents over-inflation. The AC-1966 is the practical choice for drivers who want basic, dependable tire inflation capability without the bulk or expense of larger units — a sensible addition to any vehicle emergency kit.
