Product Overview

The AC-8766 occupies a unique position in our lineup — a dual-power inflator with an 11.1V lithium battery system and a precision 21mm cylinder diameter that strikes an optimal balance between inflation speed and portability. Operating on both DC 12V vehicle power and its internal 2000mAh x 3 battery, the AC-8766 delivers up to 150 PSI with an 8-minute full inflation time for standard 195/65/R15 tires. A single battery charge supports 2.5 complete inflations — sufficient for a full set of tires on most sedans. The digital display with auto-stop functionality eliminates guesswork from tire maintenance. The 21mm cylinder represents our engineering sweet spot: faster than compact 17mm models while keeping the overall unit smaller and lighter than 22mm alternatives. The result is a dual-power inflator that does not sacrifice portability for performance. An integrated LED work light, ergonomic pistol-grip design, and quick-connect air chuck complete the package. The AC-8766 is the intelligent choice for drivers who want maximum versatility in a sensibly sized package.
