Milwaukee 12V Compact Air Compressor

[Cheese]

One of those little annoyances that never seems to go away is adjusting the air pressure in your tires when you have a TPMS (tire-pressure monitoring system) on an automobile.

Add air...check car monitor...remove some air...check car monitor...add some more air...check car monitor. [eek]  It's just an endless progression that if it finally yields all the tires to be within 2-3# of each other...well that's good enough.

Worse yet, you may have a couple of those large SUV/truck tires that need more air than usual, so that the 4 gallon portable air tank that you use has to be refilled several times and the air compressor is in the basement.  [crying]

I stumbled on this new item from Milwaukee and it sure is slick.

You can purchase the tool only for $69:  https://www.milwaukeetool.com/Products/Power-Tools/Specialty-Tools/2475-20

Or the tool, battery & charger for $159:  https://www.milwaukeetool.com/Products/Power-Tools/Specialty-Tools/2475-21XC

Photo 1: Attach the inflator to the tire and it reads out the air pressure.

Photo 2: Now dial in how much pressure you want in the tire.

Photo 3: Push the start button and the the tire will be inflated to the correct value and the inflator will then turn off. This took all of 15-20 seconds.  [cool]

Photo 4: This is the end result when you look at the dashboard monitor.

With a 4.0 Ah battery, fully charged, Milwaukee says the pump will run for 20 minutes. That's probably enough run time to fill all 4 truck tires when they're completely flat. Just attach, set and walk away.

This thing should also work well on motorcycle tires.

I have a Ryobi that does indeed work very well on motorcycle tires, camper tires, garden tractor tires, inflatable kayaks, etc.  I've never had to use it on a car or truck tire, but it seems to work well.  Got mine before the Milwaukee one came out.

[member=44099]Cheese[/member]  Thanks for the review! Thanks to the set it and walk away target psi I might have to get that inflator.

Will the pump inflate truck tires to 80psi?  That would save me a ton of time rotating tires on my truck

Milwaukee quotes a max pressure of 120 psi. They also say it takes 4 minutes to fill a LT truck tire to 35-45 psi. When I was bumping the tire from 33 to 35 psi, that literally took 10-15 seconds. I was amazed.

Home Depot offers the compressor for $79 with a 2.0Ah battery. So for $10 more you get another...2.0Ah battery. Saw it in store a couple days ago when I was picking up supplies for a job.

I thought about getting one for our other car, but having a 12 volt compressor that connects directly to the car battery means it will work 2 years later without worrying about the battery being dead. Viair is one of the leaders. I keep an air compressor and a plug kit in our travel vehicle, with a 200 piece Dewalt tool kit, and some other possibly needed tools.

A great idea. What is the weight? In your pics it looks like the gauge is very visible. All my air gauges I can hardly read without my reading glasses.

I have a tire monitoring system on our car. Only twice in 2 years have the tires been out of balance. Had we been far from home, and out in the boonies, it would have been a PITA. This looks like an easily stowable item and all one has to check is the battery life before going on a trip.

It's basically a 6" cube...weight is maybe 2#. The fill hose, screws on to the Shrader air valve so it's a simple attach, set and walk away process.

Yesterday, I used it to top off the wheelbarrow tire. It also comes with a ball inflation needle, a Presta chuck & an inflator nozzle so anything from footballs to air mattresses can be filled.

It would be perfect on a boat so rather than leaving the water toys inflated all the time, just inflate them when you need them.  [big grin]

At Acme Tools it’s $70, no tax (most states), free shipping, and if you buy at least $100 worth of Milwaukee stuff there is a $20 off coupon.

Unfortunately I'm in Minnesota so there was sales tax.  [crying]

The good news is, I ordered it on Tuesday and received it on Thursday. Two day service at no additional up-charge. [cool]

I’ve been saying for more than a year that I can’t believe Makita hasn’t already done this in their Cordless lineup... I mean seriously, they have Fans and a Coffee Maker, but no tire inflator...I think it’s great Milwaukee came out with it. I already have Car Battery Operated Comprsssors in both of our Minis’, so no need for me on this compressor. But congratulations anyway.... [thumbs up]

I was thinking about the Ryobi equivalent of this but then they bought out a 15 lb compressor with a 1 gallon tank and a regulator.  I can set the regulator at the pressure I want in the tire and air it up.  I can also jack the pressure up to 90 psi and run my nailers.  But for a purely car tool this looks like a good alternative.

[member=44099]Cheese[/member], you might want to consider getting your tires nitrogen-filled.  They won't vary pressure from season to season.  My truck came that way.  Every time I go in to the dealer, they recheck, but seldom have to add more nitrogen.  I'm thinking that I need to do this with my car, too.  [smile]

What do you do with your fancy nitrogen filled tires when you have to plug them?  [tongue]

Default is 78%.

I don't plug tires.  I make the shop remove them and do a stem or patch from the inside.  Then they could just refill with nitrogen.

The biggest benefit is nitrogen molecules are larger and are not significantly affected by temperature changes.

I bought this inflator a while back, and like most Milwaukee tools, it is excellent.  However, one nitpick is the screw-type connector.  I found that when the unit was done inflating, I would always lose pressure while unscrewing the hose from the valve.  There is just no way to unscrew it quickly enough.  The solution was to buy one of these quick release adapters that pop on and off:

Use a nitrogen plug, of course.  [big grin]

Hey Sparky that's interesting, I never heard of that before. Is this common at a tire changing business (say Tires Plus) or is it more of a dealership thing?

I always thought of getting nitrogen put into your tires as a gimmick.  I felt like it was just another way to get more money out of you. 

Costco put nitrogen in my tires when I bought a set of 4 new tires.  It was part of their all inclusive installation, mounting, and balancing fee.  They put those ugly green valve stem caps on to indicate that they had been filled with nitrogen.  I immediately replaced all 4 caps with the standard black caps.
