Milwaukee 2475-21XC M12 Compact Inflator Kit

I originally purchased this unit in the hopes that it would work well with my 1 ton truck, and it does... kinda... While the inflator is rated to 120 psi, I can only imagine the amount of run time it would take, not to mention the batteries required. The tires on my truck are set to 80 psi, and even just getting from 70 to that takes more time than I expected. Not to mention it really drains the battery. However, when I did get a flat, I was able to get the tire from 0 to ~65 psi on a full charge, at least long enough for me to move the vehicle.

The real issue lies in the batteries, rather than the inflator is what I've found. The kit I purchased came with an XC 4.0 Extended Battery, and to inflate about 10-20 psi requires about 50% from a full charge. I would like to see the boost in efficiency with the 6.0 battery, but I haven't been able to get my hands on one yet.

Overall it does the job well, but I would recommend this more to people that have cars/suvs/light duty trucks, rather than heavy duty vehicles.

Just bought this product tonight got home and topped off a total of 9 trailer tires most from 30 to 50psi i payed close attention to the 10 min duty cycle in the instruction manual it never over heated and gave it more than the recommended rest breaks then all of a sudden it began letting all the air out of the bottom of unit sounded like a pop off valve stuck open highly dissapointed now have to drive all the way back to the next town tommorow to see if they will exchange it for a bother brand eben though I have thousands of dollars in milwaulkee tools im very pleased with.

I own several inflators, from air compressors to portable 120v units, to low psi high volume compressors to battery powered units. This Milwaukee Inflator is by far (5+ stars) very best by far to “maintain your tires” at the correct pressure and use AS INTENDED.

No... it won’t inflate your giant off-road tires from zero PSI, pump up all 18 tractor trailer tires or get you an 18-point buck at hunting season like some poor reviews would like you to think it should. It’s perfect though for the things it was specifically designed for such as: bringing all your car tires up by 1-5 psi when the cold weather hits or your yard equipment tires, etc... better then any other inflator.

Occasionally a low star review may have a valid point but most low stars for this product are because the owners use the product in ways it was not intended.

I keep this compressor in my tool box. I work construction and often find screws in my truck and trailer tires. Works great to top off the tire until I make it to the tire repair shop. I recommend using an xc battery. I highly recommend this tool

Just purchased this to have while traveling. Had an opportunity to use it to inflate tire on a car we use infrequently. TPMS said tire was low. Connected the compressor showed the current pressure was 19 psi. Set the target pressure at 35 psi and hit the inflate button. In less than 2 minutes the tire was at 35 psi and pump stopped automatically. Was happy to see there is also a presta valve adapter included. The secure threaded connection to the stem is awesome too. No need to hold a leaky air chuck against the valve stem. Tempted to buy another one for my other vehicle.
