Milwaukee 2475-20 M12 Compact Inflator
Works absolutely well like it should

Great product
Light weight. Great for adjusting air pressure in car tires after a long winter.

After the sudden temperature change from -24 to 55 degrees, all the tires on both of my vehicles lost air. The inflator pumped up all 8 tires with no problem and with plenty of battery power left. 2 of the tires only had 5 lbs of air in them! I am very impressed with the unit.

Another great cordless M12 tool
Have used Milwaukee tools for a very long time, but I really love their cordless line. Have used other cordless brands, but they keep changing battery voltages so newer tools means more batteries...hate that. The M12 line is lightweight and very powerful for lightweight tools. The inflator performs very well, and the digital display makes using it a breeze. Compact and easily stored. Their is some noise, but I didn't buy it to blow up inflatable dolls, and I really like the ability to set the pressure and leave it until you hear it reach the setting and disconnect the hose....DONE

Handy, but could have been better as an M18
It's ok, I have no idea why they didn't make this an M18 tool. It's fine for bikes, ATV and small cars, but it barely got one truck tire aired up though.

Works great, small and easy to use
Works great. Much better than dragging out the compressor and hose.

For me it replaced an older low end sears compressor I left in the garage just for tires and it was great to get that compressor out of the garage and stick this in a cabinet.

Loud but not as loud as a small standard tank compressor is. May need 2 batteries when your tires are really low or when doing big tires on a SUV.

Inflater for the masses
If you have any type of tires to fill or toys to inflate set it and forget it. Easiest way i know of to get all 4 tires within 1 psi in less than 10 minutes. install a battery, set the pressure, connect it to the valve stem and let it run. Once it stops the set pressure is displayed no fuss no muss. I check it against the TPI in a 2018 vehicle and after they normalized all tires were at the same pressure. Also used it to charge a water pressure tank, set it to the boiler pressure and let iot do the work.

Extremely convenient.
I’m a retired homeowner with many tires. Two autos, riding mower, yard cart, wheelbarrow, camper, hand truck, bicycles, etc. This M 12 inflator is great, it’s convenient, dependable, accurate and a timesaver. I don’t need to haul an air compressor with extension cords to fill a tire, sure this inflator is slower to fill a tire, but it actually saves me time in the long run. I already have several M12 tools and batteries and am very satisfied with all of them. Battery time for most uses (topping off pressure) is more than adequate with a 2Ah or 4Ah battery. If you need to fill several auto tires then you need a compressor, this tool will do it but you will need to be patient and recharge. Be sure to let it rest/cool after about 10 minutes of continuous use. It is great for most of my needs.
