ARB CKMP12V2 PORTABLE AIR COMPRESSOR HIGH OUTPUT and PERFORMANCE in a HEAVY DUTY BOX with upgraded features

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.

Works as advertised and appears to be extremely durable.

Never failed, used in various scenarios.

This is more expensive than competitors but worth it. It works really well, I like that it has a switch and is in a box instead of a bag. I can probably mount it in the vehicle later if I decide to do so. You’re not going to set speed records while airing up tires with it but if you’re in a hurry you probably shouldn’t buy a portable compressor.

33 x 12.5 x17 off-road tire 15lbs to 30lbs in 1:46 seconds.Not bad for a little Compressor.

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.

Takes longer to fill tires than expected but works. It takes about 20 minutes for four 33" tires from 15PSI to 41PSI. The air hose broke on second use.
