Overview
Powering this inflator takes a battery on the M18 connector, and a long hose reaches the tire valve from a plastic body. Operation mode is listed as manual, and the red housing carries the Milwaukee M18 name.
Owners of M18 tools get an inflator that shares their existing battery system, which removes a separate charger for tire work. The weight and body size are those of a workshop tool rather than a glovebox item. The listing names the inflator alone as the included component.
Who it's for
Job sites, shops and driveways where M18 packs are already charging are the natural setting. Drivers with no Milwaukee battery system face an extra purchase, and those wanting something compact for a trunk should look at a smaller cordless unit.
Pros and cons
- Runs on M18 lithium-ion batteries
- Long hose for reach
- Long warranty listed
- High maximum pressure
- Battery not listed as included
- Heavy and bulky for a glovebox
- Airflow rate missing from the specs
- No automatic shut-off mentioned
Performance notes
Fill speed depends on the motor and on the battery pack in use, since all the power comes from the M18 pack. In manual mode the user ends the fill, so attention to the pressure matters more than with a preset unit. Hose length decides how close the body has to stand to the valve.
