Do they have a chart like the ARB compressor? I'd like to see amp draw and cfm for the complete range of the rated cfm.

I’d like to see cost and honest spec comparison like the ARB graph between the hardwired Wolfbox and the ARB twins both standard and brushless. I’d like to see some real world test like airing up a set of 37s using a 4 way inflator from 10 to 32 PSI, maybe 4 times back to back.

Looks like a Moorflate TenSix clone, assuming similar internals it should work pretty well. The TenSix rates 10.6CFM @ 0PSI. They do say it's only meant to inflate multiple tires at once, not sure if this one would be any different.
I have aired up my 37s many times, and am usually packed up and ready to go long before the ARB twins have finished.

I drank the Koolaid and ordered one yesterday. I have been using a Milwaulkee and been very happy with it. It takes about 4.5 minutes per tire to inflate the tires from where I like to run them.

I have an arb twin already hard mounted. i don’t need another compressor portable or otherwise.

Send the hard mounted version to someone on this forum with at least 37s. Not someone who is just going to spew BS because they got free stuff or are hoping to get more free stuff in the future. I’d like to see some real world test like airing up a set of 37s on a hot day using a 4 way inflator from 10 to 32 PSI, 4 times back to back.

I have the Smittybilt 2781, It will do 4 x 37s at once in less than 5 min. It is running 5.65 CFM. I havent done it a bunch of times in a row though.

From / to what PSI? Maybe my 2781 was defective, but it seemed to take forever to air up my 33s from around 14 to 35 in my first Rubicon. I was just doing them one by one though.

The cord was also aggravatingly prone to getting tangled, the connectors were cheap AF, it got extremely hot, and it was a PITA to get crammed back into the slightly too small bag. The rubber part of the line lasted about a year before it started leaking. Sorry, not a fan of Smittybilt's compressor.

Looking at it now though, it seems like they've at least improved the connectors. When I bought mine in mid-2020 they were the manual screw-on type.

Sorry, I usually run around 13/14psi.

I dont use any of the air stuff it came with either as I connect my quad filler directly to it.
Dont think mine has any screw on connectors. I will say it does not like running off 7 pin either. Ran super slow and cable was getting too warm for my liking. So I clamp to battery.

I'm surprised to hear of people running compressors off their 7 pin. Like you noticed, that voltage drop would really hamper its performance.

Mine Smittybilt 2781 works fine, for how much it cost me. Going from 12psi to 27-28psi in about 3 mins using two way inflator, so about 6 mins or so for all. 37s. I mounted it to a hard toolbox and added the pressure switch. It turns off when it reaches 110 or 120 psi and turns back on when it drop down to 90 or so, I can't remember. The hose fitting was also updated to the standard air chuck fittings. All in about $150 for my air setup.

I never competed in air up contest, nor has anyone in my wheeling group ever waited for me to air up. We all have plenty of time chatting at the staging area before we finish the day. As long as it gets the job done within a reasonable time, I am good.

Works fine for me too. Not the fastest. Maybe 10 minutes at most to fill all four 35s from usually about 18psi up. Gives me time to walk around for a minute and inspect the Jeep for beauty marks.
