    Can I use this with a nail gun?
    ByDec 31, 2025
    1 Answer | 
    Answer This Question

    Hi, Johnny. The Milwaukee M18 Inflator is designed primarily for inflating tires and other objects requiring air pressure. It is not intended for use with a nail gun, as nail guns require a specific type of air compressor or power source to operate effectively. The inflator does not provide the necessary continuous airflow or pressure required for pneumatic nail guns.

            Answer This Question

            Yes, the Milwaukee M18 Inflator can be used to inflate an air mattress. It includes an inflator nozzle attachment, which is suitable for such applications. However, ensure the air mattress's required pressure is within the inflator's maximum PSI rating of 150 PSI.

              I have a boat trailer for a 5000 lb boat with tires requiring 70 psi . Can this do the job of filling the tire in one cycle or will it require cooling?
              ByNov 26, 2025
              1 Answer | 
              Answer This Question

              The M18™ Tire Inflator is capable of inflating tires up to 150 PSI, making it suitable for your boat trailer tires that require 70 PSI. However, the inflator has a temperature protection feature that may require cooling after extended use. Specifically, the tool should cool for at least 10 minutes if the temperature protection indicator activates. Additionally, to avoid overheating, the tool should cool for 40 minutes after 20 minutes of continuous use.

                Explain duty cycle? How long can this inflator run before it needs to cooldown?Mike
                ByNov 20, 2025
                1 Answer | 
                Answer This Question

                Hi, Mike. The "duty cycle" refers to the percentage of time a tool or device can operate continuously within a specific period before it needs to rest or cool down. The Milwaukee M18 Portable Inflator has a duty cycle that requires it to cool down for 40 minutes after every 20 minutes of continuous use. This is to prevent overheating and ensure the longevity of the tool.

                  Bought one last year and purchased the LockNFlate hose adapter. It has been absolutely fantastic, it barely uses any power and airs up tire super fast even 90 psi boat tires. Get One Already
                  by
                    This tool is a must have especially if you already own Milwaukee tools. This inflator is so convenient. I don’t have to fire up my big air compressor and roll hoses out. I’ve only used it so far to top off air pressure during temperature drops but so far seems to be worth it. I’ve also used it to air up, semi truck tires.

                    Honest Milwaukee review
                    Best inflator I have ever owned, fast and easy to use, only down side is the connection hose end, but I bought a $10 tire hose adapter for easy connection to the stem, but other than that no complaints.
                    by
                      The portable inflator works surprisingly well! Inflated both my car and my wife’s car, all four wheels, very quickly. The device was quite easy to use to the exact proper level. Reason for the average review was due to the fact that the batteries were not charged after 8 hours of charging. I thought it might be my charger but I have two and tried 4 hours on each.

                      This is a excellent tire inflater if your using the Milwaukee M18 system. I've used it to inflate all sorts of tires from normal car tires, 10 ply 80psi truck tires and trailer tires. I've used it on 90 degree days to 10 degree days and it worked perfectly. Best of all using the M18 battery system when it runs low on power just change out the battery and keep going.

                      This inflator is an awesome addition to my Milwaukee collection. It has more pressure than expected for a Cordless item. I have had 2 of these for a couple of years and use them daily.
