Milwaukee M12 Compact Tire Inflator Quick Fill Unit
We've reviewed several battery-operated inflators, and most do a decent job. The Milwaukee M12 Cordless Compact Tire Inflator ( 2475-20) is dedicated solely to tire inflation (high pressure). This 12V tire inflator stores easily on a shelf or in your work truck or trailer, and we love the integrated handle and compact design.
How Fast Does the Milwaukee M12 Compact Tire Inflator Work?
This is the first tire inflator Milwaukee has produced and they already claim that it is the "fastest". how fast?
Well, the Milwaukee Cordless Compact Inflator can inflate your car tires (from 28 to 35 psi) in under a minute. It can even boost your LT truck tires from 30 psi to 45 psi in 4 minutes. The compact inflator also has a maximum capacity of 120 psi. Therefore, it can handle many different high PSI applications. This includes anything from performance bike tires to Low-profile 275/80R/22.5 LRG tires (in a pinch).

The M12 Cordless Inflator features a backlit digital LCD gauge that displays your target pressure and current pressure reading. When that target pressure is reached, an auto-shutoff feature protects your tires from overinflation. It also prevents the motor in the tool from overheating.

The Milwaukee M12 Compact Inflator features an ultra-portable form factor. Stores easily in your car or truck. It also weighs only 6.5 lbs, so you can take it with you wherever you need it.
