Key features & specs

How it compares

In the world of cordless tire inflators, this unit sits at the top of the performance spectrum. It delivers air significantly faster than 12V plug-in units or smaller handheld 12-volt cordless alternatives, making it more comparable to a small pancake compressor than a standard portable inflator. While more expensive than entry-level handhelds, its TrueFill technology ensures higher accuracy than mechanical gauges found on budget models.

How to use it

1. Connect the M18 battery into the base of the unit until it clicks.
2. Secure the brass twist-on chuck onto the tire valve stem.
3. Set your desired target pressure using the digital display and arrow buttons.
4. Press the start button to initiate inflation; the tool will auto-shutoff once reached.

Frequently asked questions

Is the Milwaukee M18 Inflator worth it?

Yes, the tool is worth it for users who need to fill large tires quickly without the hassle of cords or slow handheld devices. It saves significant time compared to lower-voltage competitors.

Does it work for tractor tires?

The M18 Inflator is highly effective for tractor and trailer tires up to 150 PSI. Its high CFM rating allows it to handle large volumes that would burn out smaller motors.

How does it compare to a pancake compressor?

It offers comparable localized pressure for tires but lacks the tank storage needed for pneumatic tools like nailers. It is strictly an inflation specialist focused on portability.

Is the gauge accurate?

The TrueFill technology provides professional-grade accuracy within 1 PSI. This eliminates the need for a secondary handheld tire gauge check.
