The Milwaukee Fastest 18V cordless tire inflator. The M18 inflator delivers fast, accurate, easy inflation with the portability to take anywhere. Optimized for passenger, light truck, and other medium-duty tires. Rated to deliver max 150PSI, the high efficiency motor tops-off 33 in. light truck tires in under 1 minute.
