      Answer This Question

      The product description states that this is the ‘TOOL ONLY’. You can purchase the kit (that includes the battery) for $349. I believe they also sell a complete kit with the Inflator, Battery AND Charger for over $400+.

        Will it inflate to 125 psi
        ByAug 16, 2026
        1 Answer | 
        Answer This Question

        Yes, the M18 18-Volt Lithium-Ion Cordless Electric Portable Inflator (Tool-Only) has a maximum pressure of 150 PSI and is designed to handle tires over 100 PSI. So inflating to 125 PSI is within its rated capacity.

          Is the included presta chuck plastic or metal? Quick attach or screw on?

          Answer This Question

          The attachment point is brass and screws on easily to the tire valve.

          By|Aug 31, 2026

            The M18 Cordless Portable Inflator includes a Presta chuck that is metal and it uses a screw-on connection, not a quick-attach clip. This ensures an airtight seal for high-pressure applications like bike tires.

              When asked if this works with bicycle tires, You keep answering " The M18™ 18V Cordless Tire Inflator is optimized for passengers, light trucks, & other medium-duty tires." So let me ask it a different way. Do you recommend NOT using with bicycle tires?

              Answer This Question

              You can use the M18 Inflator on bicycle tires, but with caution. It’s optimized for car/light truck tire volumes, so it inflates very fast. To avoid over-inflation, set the PSI on the digital gauge and let the auto-shutoff feature stop the pump.

              By|Sep 4, 2026

                (3)

                You can set a desired inflation pressure and the inflator will stop when that pressure is achieved. So there is no concern with overinflating a bike tire.

                  Does this tool have a "deflate" function as well? Or is it only used to inflate?

                  Answer This Question

                  The M18™ Cordless Inflator is designed only for inflation — it does not have a deflate function.

                      This package option is currently the beat deal available, considering the value of 2 6.0 ah batteries. I had previously owned the best HF inflator, but they were load, and failed at all the wrong moments. This unit fills 3x as fast and the 5 yr warranty is reassuring. I am currently converting all my critical power tools to Milwaukee so this only made sense for me. When you are flat on the side of the road or the middle of a hayfield, that is critical. This unit fits the bill

                      Best Portable Tire Inflator I’ve Ever Owned
                      The Milwaukee M18 18-Volt Lithium-Ion Cordless Portable Inflator is, without question, the best tire inflator I’ve ever owned. I bought it as part of a combo deal that included the M18 XC Starter Kit with two 5.0Ah batteries and a charger. If you don’t already own M18 batteries or want more, I highly recommend waiting for one of these bundle deals. Having two batteries means one can always be charging while you’re using the other. Before buying the Milwaukee, I owned a portable inflator from another brand. After a few years it finally failed and when I went to replace it the price had doubled. Since it hadn’t lasted as long as I expected, I started researching alternatives. Review after review pointed me to the Milwaukee, and after using it myself I can say those reviews were absolutely right. The inflator feels solid and well-built. The handle is comfortable to grip, and even with the M18 battery installed it’s light enough to carry around the car to reach all four tires. One of my favorite features is the four programmable pressure presets. I have one programmed for each of our vehicles, so all I have to do is select the preset, press Start, and the inflator automatically stops when it reaches the set PSI. Milwaukee recommends allowing the unit to cool after extended use, especially if you’re filling very low tires. But for normal use, when you’re just topping off your tires, it has no problem inflating all four quickly. I usually set it on the ground while it’s running so vibration has never been a concern. It also includes the accessories needed to inflate bicycle tires, sports balls, and other inflatables, so it's useful for much more than just car and truck tires. A quality portable inflator is one of those tools you don’t realize you need until you don't have one. With fewer gas stations offering air (and many charging for it now) having this Milwaukee inflator means I can top off my tires at home whenever I want. It has become one of the most useful tools I own.

                        Love this m18 set! It is a great addition to my Milwaukee setup. Good price. Great deal. I’d recommend them to anyone, homeowner or professional. Came with two batteries. 5 amp hours each. Can’t wait to use them. All the tools shipped together in the same box and arrived on time and in good condition. All around great deal!

                        The M18 inflator exceeded my expectations, it built sturdy, fills very fast. The auto pressure check feature is a big plus tolland gets your right on every time. Overall it is not that heavy and the sound level is on the lower side compared to 12v plug in inflator I have had

                        I am upgrading tools as I need them. I had a Kobalt inflator the bit the dust. I picked this up after reading the reviews and talking to a couple people at work that have one. It out preforms the Kobalt inflator in every way. It has a lot of power and airs up tires quick. All the accessories are mounted on the back. Does not deplete the battery as fast as the Kobalt one.

                        Very unsatisfied
                        Tool is absolute garbage used it twice, on the third time it was taking very long to air up to 15 psi. Come to find out the low quality hose failed somewhere inside.

                        We’re sorry to hear about the issue you experienced with the inflator hose. Our team will reach out to you via email.
                          The Milwaukee portable battery operated compressor is very well designed and works great! I leave it in my truck when away from the shop. It has come invaluable airing problem slow leak tires. I like the digital psi setting where you set the pressure you want and it automatically inflates the tire and checks psi as it gets closer to the set psi! Battery life is very good!
                          by
                          Dependable reliable portable Milwaukee M18 inflator is one of the best investments I’ve made. If I have low air pressure I’m able to inflate my tire and make it to the tire shop to get it checked and repaired if needed.
