Milwaukee M12 Compact Inflator Kit — 120 PSI, Digital Gauge & Truefill Auto-Shutoff

The Milwaukee M12 Compact Inflator Kit is a battery-powered, high-efficiency inflator that quickly fills car, light-truck, and compact equipment tires with accurate digital pressure control.

Lightweight and built for portability, the M12 Compact Inflator brings professional-grade pumping power to roadside, workshop, and recreational uses. Its Redlink Intelligence Truefill auto shut-off and illuminated digital gauge let you set a target PSI and leave the unit to stop automatically, while the high-efficiency pump and motor deliver up to 120 PSI capability for fast, reliable inflation.

How fast will the M12 Compact Inflator fill my tires?

Inflation speed depends on tire size and target pressure, but the M12 is engineered to restore typical car tires quickly and handle light-truck tires in a few minutes. Expect under one minute to top off most passenger car tires and roughly under four minutes for many light-truck tires when raising from low to moderate pressures.

• Car tire top-off from moderate pressure: under 1 minute
• Light-truck tire fill to working pressure: under 4 minutes
• Operates up to true 120 PSI capability for stubborn applications
• Digital gauge provides real-time readout to avoid over- or under-inflation

What accuracy and safety features control pressure?

The inflator uses Redlink Intelligence with Truefill auto shut-off to stop precisely at your chosen target, reducing the risk of overfilling. An illuminated digital gauge displays both the current and target PSI so you can verify settings in low light, while the system monitors temperature and pump conditions.

• Truefill auto shut-off for set-and-forget accuracy
• Illuminated digital gauge showing target and current pressure
• Temperature and pump protection to extend tool life
• High-efficiency motor minimizes runtime while maximizing output

Which tires and equipment are compatible with this inflator?

The M12 Compact Inflator is designed for passenger cars, light trucks, and compact equipment tires commonly found on trailers, ATVs, and lawn tools. It’s portable enough for roadside emergencies, yet robust enough for routine maintenance tasks.

• Passenger car tires — quick top-offs and accuracy
• Light-truck tires — fills to working pressure in minutes
• Compact equipment tires such as trailers, ATVs, mowers
• Suitable for on-the-go roadside use and garage maintenance

What power source and runtime can I expect from the kit?

The kit runs on Milwaukee M12 batteries (sold separately or included depending on the package) and benefits from the platform’s compact battery options for portable use. The high-efficiency pump and motor pair with the M12 power system to provide the balance of runtime and inflation speed needed for multiple inflation tasks per charge.

• Operates on Milwaukee M12 battery platform
• High-efficiency pump reduces power draw for longer runtime
• Portable form factor for roadside and jobsite mobility
• True 120 PSI capability for more demanding inflation needs
