This cordless inflator earned The Best rating from the Hammacher Schlemmer Institute because it inflated tires faster than other models. It inflated a mountain bike’s tire to 33 psi in just 31 seconds, a car’s tire to 35 psi in seven minutes and topped off an SUV tire from 30 PSI to 54 PSI in 12 minutes—all while other models took as long as a minute for a bike tire, 14 minutes for a car tire, and 17 minutes for an SUV tire. Other inflators simply burned out and failed altogether. It automatically shuts off when it reaches a desired tire pressure. The desired pressure is set using its digital pressure gauge; a squeeze and release of the locking trigger begins inflation. Recharges in three hours using the included AC adapter and comes with an 11'-long car adapter that powers the inflator directly. Integrated LED illuminates tire valves. A flexible 5"-long air hose tipped with a thread connector ensures a proper seal with valves. Includes two recreation ball and inflatable toy adapters. Includes travel case. 8 3/4" L x 2 1/2" W x 6" H. (1 1/4 lbs.)
