Milwaukee advertises that "M12 fits Everything" this is on most of the M12 packaging. The XC 3.0 Battery does not lock into the inflator.

Worth it if you already have the batteries.
Small and light weight. Aired up 3 almost completely flat car tires with a 4.0 battery still had 2 out of 4 bars left. It filled them pretty quickly as well.

I would and have recommended this product.
I’ve used it on my truck tires, and to pump up pool toys. I took it on vacation with us and and had to use it on one of the car tires that was low. Excellent product.

Milwaukee M12 inflator
This product works good if you are only topping off tires. I used it to inflate a trailer spare that only had 15 PSI in it & using ta fully charged, extended 4A battery, managed to get it to 45 PSI before the battery died. It would be nice if it had a 12 volt adapter instead of having to keep a 2-3 fully charged batteries to use it. Works really well for ATV & lawn mower tires, not so good for a fully flat tire.

To me, Best of the small inflators
I have purchased and own several small inflators because I have several cars. The most recent purchase is this Milwaukee unit. It is by far the best one I own. Most plug into the cigarette lighter in the car. Those units don’t work nearly as well as the Milwaukee! Also, the other units take a lot longer to get a tire up to recommended tire inflation. I love the fact that the Milwaukee has its own battery and will “top off” several tires before it needs a charge. This is not as good as a garage air compressor. But will suffice in most instances where you need addition air without handling a power cord or driving a car to the unit. So, it will handle most small jobs with ease!

Solid, Compact, Very Usable Air Compressor
Solid portable air compressor, decent volume flow. Have used to inflate large boat fenders, bike tires, motorcycle tires, sports equipment/balls, everyday items. I have the M12 XC 6.0 battery that runs the compressor very well. (Side Note: The M12 3/8 ratchet is fantastic


A) The ability to disconnect the air hose from the body of the compressor would be suggested. The air hose cannot be removed without disassembling the compressor body it appears.

B) The 'accessory connections' tool storage is an open air 'snap' in for the 3 plastic connections that come with the compressor. These plastic connector threads easily gall or strip. I ordered brass replacements, however, the 'storage' should be a 'box' of sorts that has a lid to close instead of an open face snap in, so that more than 3 connectors can be stored of various sizes securely.

Those two items would make this 4.5 stars.

Good value
I think it's a good value and the m12 battery fits many tools. The only thing I felt mislead about was the inflation time takes longer then advertised. I did give 1 to my girlfriend in hops she quits driving around on flat tires.

Good inflater; would be nice to have 12V cig adapt
Decent inflater, it would be nice to have had a 12v cigarette light option if conventional battery ever died.

The inflator has quickly become one of my favorite tools at work and home. Works perfectly and is a huge time saver when needed. After realizing how useful it was I bought one for my parents.

Great Tool. I really like it.
I love this little inflator. It works perfect. It has some noise to it. But not real loud. Nothing to make you uncomfortable. I use it all the time for bike tires, car tires, snow thrower tires and other jobs. Don’t have to hassle my large compressor any more. My favorite feature is you set the pressure you want and it shuts off at that pressure. Keep in mind, this is not meant to blow up completely empty tires, even though it could. This is meant to top off your tires, keep everything else up to par and do all the little jobs you used to have to haul the big compressor out for. This is well worth the $70 I paid for it. Battery life has been pretty good, and I use the bigger battery. If you purchase this you will not regret it. I have many M 12 tools. And they’re all top-notch. As a homeowner you cannot go wrong with the M 12 line
