Def recommend this. I pretty much use mine all the time on semis and trucks. 20" off road wheels filled 0 to full in like 2-3 minutes.

Just a personal note. I have used this for over year to bring with me on road trips. This is a much more robust unit that doesn't get hot after extended use. I was replacing the common small inflators that you can put in your glovebox. This inflator works well with M18 batteries. It may be capable of using a small M18 CP 2.0 battery but your really going to want to use a M18 5.0a or above. This is a great price. It is also what all the Tesla mobile service rovers use in the field.

Have used mine a few times the last few days with the insanely cold temperatures. Very handy to have and not have to mess with finding a compressor etc.

Hands down this Milwaukee M18 inflator beats everyone. Trust the reviews. I've used mine hundreds of times. Watching people at gas stations trying to inflate their tires with frustration. I bring mine out for them and all four done in 6 minutes or less. And I keep a flat tire repair kit along which I have used for these people who had no idea they ran over a nail or metal shrapnel. Don't even take the tire off.

I use this bag to hold everything

You can use to inflate sports balls, pool floats, rafts and I'm sure there are other unexpected possibilities if you look for those dual uses.

I use this valves and inflators kit

I use these air chucks, they aren't necessary

I've had this inflator since 2023 and have since sold my compressor. It's very handy for car tires, but I have also use it a lot on inflatables and even balloons.

The biggest task was a kids bounce house, not the kind that requires a constant pump. It ran for over 15 minutes. The hose got hot, but the inflator kept working. It has a fan that kicks on to keep it from overheating which I heard once the it was finished. I know I should of used a high volume low pressure pump, but I didn't have any batteries for it.

This was one of my favorite addition to my tool set. Very robust and works like a champ. Inflates pretty quickly. Just all around good. If you have m18 batteries this is a good addition if you don't already have one.

I have one and my only issue is inaccurate reading of PSI. This is only present on my large offroad tires. When I fill up my prius tires it reads the PSI fine.

Nice to see all the love for this tool in here. I was disappointed I missed the Woot deal and found this randomly. I'm pretty deep into the Milwaukee ecosystem and I use the snot out of my M12 inflator and looking forward to the upgrade. Plan to leave the M12 in the car all the time, and have the M18 around the house/shop as it's much more convenient than dragging out the air hose from the big compressor.
I have both units. Loved the 12 volt, upon getting the 18, love it even more. Handy to use both if multiple tires need done in really low temps to get it done quick. The m18 moves air probably about 2.5x as quick.

No way! I tested it on a 35 inch off-road tire, took 9 minutes to inflate it from 0 to 35psi. Which is still not bad, but ARB compressor did it in less than 4 minutes.
