Milwaukee 12V Compact Air Compressor
« on: May 19, 2018, 10:56 AM »
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.

@Cheese   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]

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.

@Cheese, 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]

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.

It's a common upsell at many places.  It costs them pennies, but they will charge anywhere from $20-50 if you want it.  I've even seen it lumped into $500-750 dealer add on packages when you buy a new car.  As GoingMyWay mentioned, Costco just lumps it into their standard installation fees rather than milking you (well, they may have done away with the installation fees now and built everything into the cost per tire).

Hey @RKA , @GoingMyWay , @Sparktrician that's indeed interesting, rather like an "old dog new trick" moment for me. [big grin]

I think I may have a minor aluminum porosity issue. It was back in May when I filled up all 4 tires to 35 psi. Just last week I noticed that they were now at the 27--29--31--31 psi levels. Outdoor temperature levels were pretty similar between then & now.

@Cheese, around here it's both a dealer thing as well as a tire shop thing.  When I bought my truck, it had Goodyear boots (with nitrogen fill) on it, and I detested them.  I bought a good set of Michelins from Tire Rack and had a local tire shop mount and balance them, and do the nitrogen fill thing on them.  That said, every time I go back to the dealer, they check the pressure and add nitrogen as necessary.  I'm thinking I may look into the possibility of getting a small nitrogen tank with a regulator and fill valve so I can do my other vehicles as well.  That option may not be cost-effective, though. 

Edit: Here's a good read on the nitrogen issue.  Having just read this, it looks like nitrogen fill is yet another dealer scheme to part you from your cash, with little real tangible value.

I have no idea what's in my tires - I assumed just regular air.  I occasionally have had to use my little air pump to add more air to my tires when the car warns me about low tire pressure.

Correct me if I'm wrong, but wouldn't sort of "topping" off a nitrogen filled tire with a few pounds of regular air negate the benefits of the overall nitrogen fill?  I'm pretty sure I have seen little cans of nitrogen being sold just to top off tires.  It must have been at an auto parts store (I rarely if ever have a need to go to one).  Or maybe I am making that up and misremembering.

@Cheese That's not bad over 5 months.  Some of my cars lose less than 0.5 psi/month and one car loses just over 1 psi/month (on summer and winter sets).  The nitrogen fill isn't going to help with that obviously.  But in the fall as the temps drop, I'm checking and adjusting pressures with each 20F drop in overnight lows.  The nitrogen will help there.

One more thing, adjust the pressures when the car is parked in the shade or garage.  I used to make a habit of adjusting them when the tires are cold, but found even if I drove the car 15 miles home, it really didn't increase the pressure more than 1-2 psi.  but if one side was exposed to the sun, the pressures on that side would increase up to 4 psi vs. the side in the shade.  If you set them all equal, that side will end up low when the tire temperatures normalize.

I guess riding a motorcycle has made me less concerned about the tires on my car... There's 4 of them vs the only 2 get on my bike. As long as the TPMS isn't going off on the car I don't give out a second thought.

Not to hijack the thread, but Dewalt has a similar model due out soon. They also have another inflator/battery jumper that is significantly more money. The only reason I am adding this is for those using the Dewalt battery system.

Being a motorcycle guy myself, I’m with you.  [big grin]

The only reason I got involved is because my wife locks-up when the TPMS light starts to flash. I just ignore it.

If you ignore it then after a couple of days a DANGER message appears on the monitor and also on the speedometer. She thinks the car is going to implode or something, she’s afraid to drive it.  [eek]

So this battery powered pump was my solution to regain some of my sanity.

Great timing of this thread. I was at the Tool Nut yesterday afternoon picking up some Woodpeckers, and there it was on the counter. They were telling me how great it was. As luck would have it, my rear passenger tire was a *cough" *cough* "little" low on pressure. With a nearly dead battery, it filled up the tire no problem, shutting off at the entered PSI.

My wife, like most of yours I'm sure, also flips out when the TPMS light goes on in her car. Almost to the point where she wants to trade it in (until I tell her all cars have the light now). This would definitely restore some sanity and seems well worth the money.

I don't have any Milwaukee cordless, but their 12 volt system just keeps expanding and getting better. This is a real winner in my book.
