GELUOXI CKMA12 High Output 12V Air Compressor System for Universal for inflating tyres

The compressor I received did not function. I tried connecting it with the supplied harness and when that didn’t work I tried supplying 12v directly to the compressor leads. It will not work. I tried getting a replacement but was told I could only get a refund. I will buy the real brand name next time.

Good quality, Arb clone

This is a solid little compressor. It’s obviously a knock off of the ARB CMA12 High Output compressor- they even have the same name. There is no ARB branding on this compressor but I suspect they would look identical otherwise. It’s impressively heavy and seems well built. It includes a heavy duty wiring harness with a compressor on switch and connections for two air locker switches (front and rear most commonly) and connections for the matching solenoids at the compressor side. It also includes a heavy duty 60amp relay and automatic pressure switch. It has a mounting base but you’ll need to get creative with finding a way to secure it since the bolts are directly underneath it. It took me a while to figure out how to secure it. I tested it with my MORRFlate 4 tire inflator/deflator system on my 35” BFGs. Airing up all 4 tires as once from 25-35psi took this compressor about 4-5 minutes. I admittedly wasn’t timing it so that’s a best guess but it did raise all 4 tires about 2psi a minute. It’s loud but not terrible, from inside the truck with the HVAC and radio on you can nearly hear it- I mounted mine under the hood. I recommend that because holy smokes this thing gets HOT, see attached pic. At one point the manifold registered 244*F after a solid 4 min of continuous inflating all 4 tires. Moving forward I will cycle it on and off a bit more when airing up.

Well it worked for about 4 weeks , and now it might turn on once in while. It seems to fill the 1.5 gal. Tank 1 time . And then it shuts off and won't come back on. I think it's getting to hot and then turning itself off.

Easy to mount. Wiring is all there. No instructions but can be found on line on ARB's site. Surprisingly quiet.
