Rated 5 out of 5 by from Very convenient and easy to store!! I bought this compact inflator because we have a fleet of cars and often have tire pressure issues. We would always take cars to the local gas station to fill up the cars, but this compact inflator was a game changer for us in terms of saving time which equals saving money. It typically take about 1 1/2 minutes to go from 20 PSI to 35 PSI on an average sedan, and about 3 minutes on a truck. I run the inflator with a 4.0 battery and have never run into a situation where the battery did not have enough juice to finish the job. The inflator comes with different nozzles that store on the back so you can inflate balls or bikes or tires. Great product!!

Rated 1 out of 5 by from This inflator is disappointing I’ve been through three of these inflator’s even though they’re rated at 120 pounds maximum if there is over 90 pounds in a tire it will not work. Also after about 10 minutes of inflating a tire at 32 pounds the unit overheats and shuts off. I returned it got another one same problem and then finally went with the third one. Same issue I have a trailer tire that’s rated at 110 pounds and it shuts off at 90. I love Milwaukee tools and enjoy everyone that I have but this one here has the quality of a children’s toy. Hopefully Milwaukee will come out with an 18 V that’s a little bit more powerful that could be used for more than just filling up basketballs and bike tires.

Rated 3 out of 5 by from Great for smaller tires and passenger tires. I use this tool all the time to fill tires in my fleet of aircraft ground service equipment. It works great with smaller tires and passenger tires for cars, but I wouldn't really bother using it for light truck and certainly not heavy truck tires. Unit isn't even worth using with a CP2.0 battery, you need to use at least a 4.0. I am on my second one, my first one failed after trying to inflate light truck tires to 80PSI. Unit overheated before the thermal protection kicked in and would no longer build any pressure. Sent in for warranty repairs and was sent a brand new one.

Rated 5 out of 5 by from I am looking to buy at least two more!!!! I didn't buy this inflator to air up my truck tires nor did I buy it to air up my car tires! I have bigger air compressor for that. I bought this M12 inflator to keep my lawn tractor tires at equal balance and also my airplane tires!!!! I love the simplicity of this Milwaukee tool!!! Screw hose onto tire valve stem, set your desired pressure and turn it on. It cuts off automatically when desired pressure is reached. It can't get no easier than that!!! I just live this little tool. It does exactly what it was built for!!! Thanks Milwaukee!!!!!

Rated 1 out of 5 by from would not buy again Worked great for small stuff, golf cart tires ect..Filled up two trailer tires to 65psi overheated and will run but not make pressure any more. This is the first Milwaukee tool that has ever failed me. Needs to be a lot more robust and prob m18 for me to buy another one.

Rated 4 out of 5 by from Over heats with 60+ psi work loads. This product is definitely worth the money and it might be the world’s fastest compact tire inflator but struggles/over heats while airing up any truck tire 60+ psi. If you had to top up all 4 tires to say 80 psi from say 65 psi. It would heat itself up enough from the work load to the point where increased wear/damage to the tool would occur. Do that enough times and you would get to the point where the tool would lose the ability to produce any work or much less efficient work. As mine did!

Rated 4 out of 5 by from Quick and easy I'm a maintenance guy at 2 childrens nursing homes. I picked this up to speed up checking tire pressures on the vans. I also use a 6ah battery for the bigger tires. Now alot of reviewers have stated how much easier these are than hauling out the compressor and hose but no one has mentioned how long it takes for their compressor to fill to pressure and bending over the whole time putting pressure on the fill chuck then stopping to check psi. then putting more in or letting too much out.this is much simpler ...screw on the valve connector turn on the little guy set pressure start the compressor unscrew the connector when it stops go to the next tire. Time is a luxury in my buisness and this little tool will save a lot for me. Just inflated 4 suv 16" tires on my brothers vehicle from 27psi to 40psi starting with a full battery 6ah. 12min latter all 4 at 40psi. Battery has one bar left. Would not try to fill our class A tire from empty but will try to top one off. This is where Milwaukee could market a larger m18 version for the rv's yes most have compressors in tow but this would be a convienance most would go for especially if they are already on the 18vt. platform just my 2 cents. One other use no-one has mentioned is not needing to use canned air... With the filler tip on this puts out a pretty useful stream of air to blow out key boards , computer fans ect. This is going into my truck..

Rated 5 out of 5 by from Just perfect works brilliantly Was very sceptical as to weather this tool would or even could perform the task I bought it for, after seeing product reviews on YouTube. Base on duty cycles and the need to run it at 80psi. My single intended use was for charging PET bottles in a bottle rocket launcher with school students in STEM activities. The launcher is designed to run off an air compressor which having a large tank provides both pressure and volume so I was worried that this would not work, having no real volume. It kinda worked at first. So after redesigning and re engineering the launch mechanism so it was able to hold a volume of air it now works absolutely perfectly every time. My concern about duty cycle isn’t even an issue in this application. It only takes about 30seconds to run up to pressure and works every time. This is a real time saver as previously we had to take a electric air compressor leads and hoses out to the oval. The air pump is brilliant and I’m finding more uses for it al the time.
