The AC-1366 combines the freedom of cordless operation with the speed of a professional-grade 22mm cylinder inflator. Powered by a robust 11.1V triple-cell 2000mAh lithium battery pack, it delivers approximately 5-minute full inflation for standard 195/65/R15 passenger tires — dramatically faster than compact portable models. The digital display provides at-a-glance pressure readings in four units (PSI, BAR, KPA, Kg/cm squared), with a programmable auto-stop function for precise, hands-free inflation. A single charge inflates up to 3 passenger car tires, making it capable of handling all four tires on most sedans without recharging. The AC-1366 features a high-torque brushless motor for extended service life and quieter operation. An integrated LED flashlight with SOS mode adds roadside safety functionality. The ergonomic handle design and balanced weight distribution make extended use comfortable. Ideal for drivers who want fast, cordless performance without compromise — perfect for SUVs, crossovers, and vehicles with larger tire volumes.
