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
- Connect the M18 battery into the base of the unit until it clicks.
- Secure the brass twist-on chuck onto the tire valve stem.
- Set your desired target pressure using the digital display and arrow buttons.
- Press the start button to initiate inflation; the tool will auto-shutoff once reached.
- Store the 36-inch hose in the integrated wrap-around storage after use.

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.
