Our verdict
The compact Milwaukee for cars and crossovers, especially if you already own M12 tools. Truck owners on M18 should buy the 2848-20 instead.
Pros and cons
Pros
- Tops off a car tire (28-35 PSI) in under a minute, by Milwaukee's figures
- TrueFill auto shut-off guards against overfilling
- Display shows target and current pressure at the same time
- Small enough to keep in a car with a spare M12 battery
Cons
- Runs only on M12 batteries; no 12 V or wall power
- Battery and charger sold separately
- Aimed at cars: Milwaukee quotes under 4 minutes to fill a light truck tire from 30 to 45 PSI
