Milwaukee M12 Gas Generator 2475-20 | Up to 120psi

Milwaukee M12 Compact Tire Inflator fills punctures quickly

We have reviewed several battery powered inflators and most work well. The Milwaukee M12 Cordless Compact Tire Inflator (2475-20) focuses exclusively on tire inflation (high pressure). This 12V tire inflator packs 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 made by Milwaukee and they already claim it’s “the fastest”. How fast?

Well, the Milwaukee Cordless Compact Inflator can inflate your car tires (from 28 to 35 psi) in less than a minute. It can even inflate your LT truck tires from 30 to 45psi in less than 4 minutes. The compact inflator also has a maximum capacity of 120psi. As a result, it can handle a whole range of different high PSI applications. This includes everything from high-performance bicycle tires to low-profile 275/80R/22.5 LRG tires (in a pinch).


The M12 Cordless Inflator features a backlit LCD digital pressure gauge that displays your target pressure and current pressure readings. When this target pressure is reached, the automatic shut-off function protects your tires from over-inflation. It also protects the motor in the tool from overheating.

The Milwaukee M12 Compact Inflator has a super portable profile. It’s easy to store in your car or truck. It also weighs only 6.5 pounds, so you can take it with you wherever you need it.
