The portable version of ARB's single motor compressor: the same 3.08 CFM, 100 psi, IP55 sealed unit as the on-board CKMA12, mounted on a plate in a hard carry case with a switch, a hose and battery clamps. Nothing gets drilled, nothing gets wired, and it moves between vehicles.
For most people running 33" tires this is the sensible amount of compressor. It airs a 33" tire from 15 to 30 psi in around two and a half minutes and does a full four tire set inside its 50 percent duty rating of 30 minutes on and 30 minutes off. If you run 35s or want to drive air tools, the twin portable CKMTP12 is the tool for that instead.
What's Included:
CKMP12V2 single motor 12 V portable compressor in a hard case
Air hose
Battery clamps
Hard carry case
Features
No Installation Clamp it to the battery and go. Nothing drilled, nothing wired, and it moves between vehicles or lends out.
3.08 CFM Free flow 3.08 CFM and 2.34 CFM at 29 psi, which is around two and a half minutes on a 33" tire from 15 to 30 psi.
Sealed To IP55 The same IP55 sealing as the on-board unit, protecting the motor from dust and water spray in a load space.
Honest Duty Cycle 50 percent, rated 30 minutes on and 30 minutes off. A full four tire air up on 33s sits comfortably inside that.
Switched And Ready A panel mounted ARB switch and the hose and clamps are packed with it, so the case is the whole system.
Hard Case A molded hard case with handles, which is what keeps a compressor working after a few years of living in a load space.
Fitment & Compatibility
Application
Fit
Any 12 V vehicle, via the supplied battery clamps
✓ Fits
Tires up to about 33"
✓ Fits comfortably
35" tires and larger
● Works, but the twin portable CKMTP12 is the better match
Air tools
✗ Not suitable, there is no tank. Use the twin portable with its integrated tank
24 V vehicles
✗ Does not fit, this is the 12 V unit
Fit guidance: Portable compressors are universal: they clamp to a battery. Choose between this and the twin on tire size and on whether you want to run tools, not on which vehicle you have.

About ARB
ARB started in 1975 in a Melbourne garage, when Tony Brown began building bull bars for the four-wheel drives crossing Australia's outback, and the company has grown into the largest 4x4 accessories maker in the southern hemisphere. Its engineering campus in Kilsyth, Victoria still designs and builds the products the brand is known for, and ARB now runs offices in the USA, Europe and the Middle East with an export network reaching more than 100 countries.
Air is one of the things ARB is best known for. The compressor line, the Air Locker system it was built to feed, and the fittings, hoses and gauges that tie them together are engineered as one system, which is why an ARB air part is specified by the same part numbers the factory uses. In North America ARB operates from Auburn, Washington as Air Locker Inc., backing every product with a US warranty program. Prestige Truck is an authorized ARB dealer. Every part we ship is a genuine US-market unit with full ARB North America warranty coverage.

Why A Premium ARB Compressor
ARB walks through what separates its compressor line from bargain units: sealed motors, real duty cycle ratings, serviceable filters and the electrical kit that comes standard.
If you are comparing this against a parts store special, it is the honest comparison from the people who build it.

Frequently Asked Questions
Straight answers on specs, fit and support
Single or twin, which do I need?
On 33" tires and without air tools, this single is the right amount of compressor. On 35s and up, or if you want to run tools, the twin portable CKMTP12 doubles the air, raises the pressure to 150 psi and adds a tank.
Do I need to install anything?
No. It clamps to the battery and the hose comes with it. That is the entire setup.
Can I plug it into a cigarette socket?
No. It draws up to 32 A and the battery clamps are supplied for that reason. An accessory socket cannot supply it.
How long can I run it for?
ARB rates the duty cycle at 50 percent, 30 minutes on and 30 minutes off. A four tire air up on 33s from trail pressure sits well inside that.
What is the difference from the CKMA12?
The compressor is the same. The CKMA12 is the on-board version that bolts into the vehicle and wires to a dash switch. This is the portable version in a case with clamps and a hose.
Why is there no installation video?
There is nothing to install, and ARB has published no compressor installation film of any kind for any model in the range.

Look is great. 100 lbs
Look is great. 100 lbs lighter than my 2nd pick. Lid lock and opening are smooth. Only minor knock I give is the the tie down hooks are hard to install - thinking I should have done them before installing.

A must have
I really like this mat. I was apprehensive at first but, the mat does a great job of keeping things from sliding around without having to secure it. perfect fit. But i think i will be adding some short screws to secure the mat to the DECKED system.

I never knew how much I needed this
As with all BAK covers, the quality is amazing. What I didnt fully appreciate until installing was the ease of opening - especially in a lifted truck. No more need to find the right handhold. Just roll it back with a single hand. Its also great to see out of my rear window when fully open - something you lose with the fold back covers. Customer service is awesome. I has an installation question and the representative stayed on the line as I adjusted an alignment to ensure I did it properly.

Better then expected.
Searched for about 6 months to find the tonneau cover. I really wanted the security of a hard top without sticking above the bed rails it checked those boxes. I also did not want to drill my truck bed. The install was super simple my wife and I had it on the truck in about a half an hour.

The toolbox is nice. I
The toolbox is nice. I think Ill get a lot of years of service out of it. I like how the lid opens and the tie downs are a nice touch. It seems to be well built. And tough. Im pleased with my purchase and would buy another one.
