Key Features

Fast Tire Top-Offs

The Milwaukee M12 Compact Inflator is built to handle car, light truck, and compact equipment tires quickly. It tops off a car tire from 28 to 35 PSI in under 1 minute and fills a light truck tire from 30 to 45 PSI in under 4 minutes.

Set It and Stop

TrueFill auto shut-off lets you dial in the target pressure and walk away from guesswork. That means more accurate inflation, less risk of overfilling, and less time crouched next to the tire.

Truck Ready Size

Compact dimensions, anti-vibration feet, and a reinforced cage make this cordless inflator easy to stash in a vehicle and stable while running. It is made for roadside use, service calls, and quick air-ups without dragging out a larger compressor.

Overview

The Milwaukee 2475-20 M12 Compact Inflator is a cordless inflator built for fast, accurate tire inflation on the go. This is a cordless inflator designed for tire inflation and pressure top-offs. Model Number 2475-20. If you already run Milwaukee M12 batteries and want a compact tool that lives in the truck, garage, or trailer, this is the kind of tool that saves time the first time a tire is low and you do not want to mess with a full-size compressor.

What makes this inflator matter is how it balances speed with control. Milwaukee rates it for true 120 PSI capability, and the high-efficiency pump and motor are built for more than bike tires and beach toys. It is meant for car tires, light truck tires, and compact equipment tires. On the job or on the road, that means you can top off passenger vehicle tires quickly and handle more demanding inflation work without being tied to an outlet or a bulky air tank.

The standout feature here is TrueFill auto shut-off. In practical terms, you set the target pressure, start the fill, and the tool shuts off at the desired PSI. That matters because tire work is usually done in a hurry, often in awkward positions, and usually while multitasking. The digital gauge gives you both target and current pressure readings on a back-lit display, so you are not guessing, counting seconds, or checking with a separate gauge every few moments.

Milwaukee also built this unit like a tool, not like a glovebox gadget. The reinforced cage helps it deal with vehicle storage and jobsite bumps, while the anti-vibration feet keep the tool from walking around while it runs. The 26 inch hose gives you enough reach to work around the valve stem without fighting the tool body, and the all-brass Schrader chuck is the right call for repeated tire use because it is more durable than cheap plastic fittings.

From a portability standpoint, the 6.5 inch length, 6.5 inch width, and 7.5 inch height keep it easy to store in a truck compartment, back seat bin, or service van drawer. At 3.83 pounds, it is light enough to carry one-handed but still substantial enough to stay planted while running. That is a useful middle ground for mobile technicians, contractors, and anyone who wants a real cordless tire inflator without jumping up to a much larger platform.

As a bare tool, the Milwaukee 2475-20 M12 Compact Inflator is meant for users already invested in the Milwaukee M12 battery system. It runs on M12 batteries, so it drops into the same platform used by a wide range of Milwaukee compact cordless tools. In the box, Milwaukee includes a ball inflation needle, Presta chuck, Schrader chuck, and inflator nozzle, which broadens its usefulness beyond vehicle tires to sports equipment and other inflation jobs that come up around the house, shop, or trailer.

This is a smart buy for mechanics, mobile service techs, contractors, and serious DIY users who want a compact cordless air solution for routine tire maintenance. It is especially good for anyone who needs something faster and more accurate than a cheap 12V inflator, but does not need a full compressor setup. If your main use is topping off tires, dialing in pressure accurately, and keeping an inflator in the vehicle at all times, this one makes a lot of sense.

Quick Inflation Without Dragging Out a Compressor

This inflator is built for the jobs most people actually need: topping off car tires, handling light truck tires, and keeping compact equipment ready to roll. The big advantage is getting compressor-like convenience in a small cordless package that is easy to keep close by.

• Rated for 0 to 120 PSI for tire inflation and air-up work
• Fills a light truck tire from 30 to 45 PSI in under 4 minutes
• Compact 6.5 inch by 6.5 inch footprint stores easily in a car, truck, or van

Dial In Pressure More Accurately

The digital interface is what separates this from basic inflators. You can set your target PSI, monitor the current reading, and let the tool shut off automatically when it hits the number you want.

• Back-lit LCD shows current and target pressure
• Gauge accuracy is rated at plus or minus 3%
• TrueFill auto shut-off helps prevent overfilling and improves repeatability

Works With More Than Just Standard Tire Valves

Milwaukee includes multiple inflation attachments, so this tool is not locked into one kind of valve. That makes it more useful for mixed vehicle, bike, and recreational gear setups.

• Includes Presta chuck for compatible bike and specialty valves
• Includes Schrader chuck for common tire valve applications
• Also includes a ball needle and inflator nozzle for general inflation tasks
