ARB CKMP12 Portable Air Compressor 12V High Performance and Output Compressor

Perhaps one of the best tools I own. I use it to keep my motorcycle, SxS, and truck tires inflated while traveling. It works great.It can get hot since it is mounted in the box. It got hot enough to shut off on me after airing three of my 35-11.50X18 tires up from 50psi to 70psi. Not a problem, you just need to realize that the single pump without a tank works awfully hard to move that much air. I rested it for about 15 minutes while fanning a little air over it and it finished the forth tire just fine.ARB - accept no substitutes.

Used this compressor to air up after wheeling multiple times over our recent road trip. A great feature is the pressure shut off switch so when your checking tire pressure or moving to next tire it build pressure in hose then shuts off. As soon as you clip to new valve stem starts up. ARB offers a chuck with a built in gage I might consider. The only “ding” is the ARB air chuck sticks straight out (it’s only about 2” long) so makes the air hose end kinda long so even with the valve stem lock I found that I needed to hold it. When valve stem happened to be near the 12 o’clock position I could let it hang there. Worked great whether we were 90+ degree heat of Arizona (Kaibab National Forest) and Utah (Sand Hollow State Park and Moab) or at altitude after Black Bear and Ophir Passes. Currently running 33s KO2s on my 2020 Rubicon. Took maybe 1.5 minutes to air up each tire from 15psi to 36 psi per tire. I was impressed that in hot temps it didn’t over heat. As expected the compressor did get very hot after use, so I always waited to put hose back in the case. Good quality battery clips, hose and sturdy carry case.I know there are cheaper options but I definitely recommend this kit. If you’re running 37s or bigger maybe consider the twin.

This kit efficiently and quickly inflates all 4 of my 35's from 20lbs. to 38lbs. in less than 3 minutes total. It shuts off when disconnected from the tire so it doesn't get too hot and takes up very little space. The hose reaches all 4 tires easily. I am really pleased with the quality and performance of this kit.

I've run this for a few years now, use it regularly; case is very convenient for stashing a couple extra compressor related tools. Unit has had zero issues, inflates 80 psig tow vehicle tires, 35" offroad truck tires, and with the case, is convenient to pop in the track car for HPDE. Got what I paid for, highly recommend.

Works as advertised and appears to be extremely durable.

I struggled for months with spending this much money on a compressor when there are SO many others for less money - I tried close to a dozen others on different terrains/tire sizes/etc. and finally decided go for it. ARB has never let me down: this product is reliable every time, fits nicely in the box, parts are easy to replace (fingers crossed, I’ve had great luck with not busting a hose), doesn’t overheat, and fills even big tires quickly. The box is easily portable and compact for fitting into camp gear.Perfect buy.

Never failed, used in various scenarios.

This is a great compressor, it works well to air up our 265/70-17 tires on the 4Runner. Quick and easy. The only complaint is that the case is rather bulky. I should have gotten the kit to install the compressor under the hood of the car. I will do that in the long term, but I should have started this way, since I know have to spend significantly more than the "under hood install" pump.My recommendation: if you're looking for a pump to air up your tires after off-road driving, get one that installs directly to the car somewhere and be done with it. It'll be cheaper in the long run.
