Design & Build
Milwaukee is known for thoughtful, rugged tool designs—and the M18 Inflator is no exception. Right out of the box, you’ll notice its compact footprint and striking red-and-black color scheme that matches other Milwaukee cordless tools. It’s small enough to store behind a truck seat or in a car trunk, but has the toughness you’d expect from a job-site tool.
The exterior housing is made of reinforced plastic with rubberized edges for enhanced durability and grip. The carry handle is perfectly balanced, making it easy to lug around one-handed. Buttons and controls are ergonomically placed on the top panel, with the LCD digital display front and center.
Everything about this inflator says “rugged convenience.” Even the storage compartments for hose accessories are neatly integrated so nothing gets lost.
Features & Functionality
This isn’t just a basic inflator—it’s a smart device that fits into the Milwaukee cordless ecosystem. Here are the standout features that make the milwaukee 2848-20 m18 inflator one of the best in its class:
1. Rapid Inflation Speed
Time is money, and this inflator knows that. It’s capable of topping off a standard car tire from 28 to 35 PSI in under one minute. Thanks to its powerful M18 motor, it delivers up to 150 PSI maximum pressure. That means it’s effective for inflating everything from bicycle tires to light truck tires without breaking a sweat.
2. Digital Interface with Auto Shut-Off
The LCD screen gives you real-time pressure readings, and with the easy-to-use dial, you can set your target PSI. Once it reaches your set value, it stops automatically—no guesswork, no over-inflation.
3. Cordless Convenience
It runs off Milwaukee’s M18 REDLITHIUM battery pack—the same one used across dozens of Milwaukee tools. This eliminates cords, extension cables, or needing a 12V car port. You’ll appreciate this portability on the road or job site.
4. Accessory Storage and Hose Wrap
The 26” hose wraps neatly around the unit, and integrated compartments hold the different inflation adapters. It’s these small touches that make a big difference over time.
Ease of Use
Setting up the Milwaukee M18 inflator is easy even if you’ve never used a portable air compressor before. Simply pop in a compatible M18 battery, attach the hose to a valve stem, and set your desired pressure on the digital dial.
The menu options are intuitive and straightforward. The bright digital screen is clearly visible, and the touch-button interface is responsive. Plus, the auto shut-off feature prevents overfilling—a huge stress relief.
One thing I absolutely love is how quiet it operates for such a powerful inflator. While not silent, it’s significantly less jarring than past generations of battery-powered compressors.
Performance / Effectiveness
Performance is where this tool really shines. The milwaukee m18 inflator review wouldn’t be complete without noting its high output and reliability. Whether you’re filling a low tire, inflating sports gear, or topping off your riding lawn mower tires, it handles it quickly and efficiently.
The digital pressure gauge is accurate within a reasonable margin, and the inflator can manage multiple tasks on a single M18 battery charge. Although run time will vary depending on PSI and battery size, most users will find it more than sufficient for everyday needs.
I tested it on a set of SUV tires, and this inflator took only 50 seconds to reach the desired 35 PSI from 30. It never stalled, didn’t overheat, and remained stable throughout the process.
Value for Money
Compared to other options in the market—some of which require separate 12V power sources or don’t offer auto shut-off—the milwaukee 2848-20 m18 inflator unquestionably delivers solid value. It combines speed, reliability, and portability in a compact shell—all built around the renowned Milwaukee reputation.
Sure, you must purchase the battery separately unless you already own M18 gear, but that’s a worthwhile investment if you’re already in the Milwaukee ecosystem.

Alternatives & Comparisons
An alternative to consider is the Dewalt 20V MAX Cordless Inflator, which offers similar performance, digital pressure settings, and cordless design. It’s a strong competitor for those invested in the Dewalt battery ecosystem. However, it’s slightly bulkier and not as seamless in hose storage and portability as the Milwaukee 2848-20 M18 Inflator.
