The AC-8166 bridges the gap between corded reliability and cordless convenience with its innovative DC 12V + 7.4V lithium battery dual-power system. Use vehicle power for unlimited runtime during multi-tire sessions, or go cordless with the built-in dual 2000mAh battery for quick top-offs anywhere. The 17mm cylinder delivers up to 150 PSI, inflating a standard 195/65/R15 tire in approximately 10 minutes on battery power. The digital display shows precise pressure readings with auto-stop preset capability. One battery charge provides up to 1.5 complete inflations. The AC-8166 features a slim profile that stores easily in trunk organizers and under-seat compartments. An integrated LED work light, ergonomic grip handle, and comprehensive adapter kit for sports balls, bicycles, and inflatables make this a truly versatile inflation solution. Ideal for drivers who want the flexibility of both power sources without the bulk of larger dual-power units.
