Really? I have searched and haven’t been able to find any.Why so fixated on running a 12V compressor? There are numerous 24V compressors in the same price range that are lower risk to your electrics and don't require so much effort.

Mogman and I both purchased former millitary 24V compressors meant for jet airplane fuel delivery. Each unit comes with two 24V heavy duty air compressors. They are AWESOME!!!

Those Extreme Outback compressors are not cheap, I have not seen any on the surplus market lately
Does anyone own one of these battery powered air compressors? I have tons of RIDGID batteries and would bring my impact with me anyways. They have two to chose from.

I would imagine that it would take forever to pump up a 395 sized tire. Every one of those things don't list a CFM rating that I have found. On the other hand, if you had nothing - it might be better than that... Just be sure that you have a clip-on air chuck so it can run until the battery dies, then swap it and go again.

The only rating I could find for the Ridgid was 16 scfm for the low pressure blower tube, but for the high pressure I don't see anything obvious, even in the owner's manual.
Most of them bury it in the owner's manual.
The Milwaukee 18V inflater has ratings of 1.4scfm @ 0psi and 1.1 scfm @ 35psi.
for a little more money than the Milwaukee inflator, the 18V Milwaukee 2 gallon air compressor has 1.7 scfm @ 70psi and 1.2 scfm @ 90psi. A year ago the inflator was on sale and instead I fell down the rabbit hole and got the compressor instead (I already have the 12V inflator for keeping in my car) with a "free" 8 amp Forge battery to power it (which made the M18 inflator on sale the same basic price if you had to also buy a battery to go with it.
Don't forget with most of these portable inflators, there is a duty cycle.
They typically use a 10 minute increment.
The Ridgid has a 50% duty cycle, so every 5 minutes you have to turn it off, wait 5 minutes, then you can use it for another 5 minutes.
The Milwaukee M18 inflator has a duty cycle of 33%, so 3 minutes on, 7 minutes off.
The M18 compressor has no duty cycle listed, so supposedly 100%, but I can neither prove nor disprove as they like to advertise how many nails it can shoot on a charge, not how long you can push air into a tire.

Respectfully, I have owned a rigid air compressor for over a decade and I have never paid attention to the duty cycle. There are times I’ve had it running for 15 or 20 minutes at a time.

I don't know which ridgid air compressor you have had for over a decade, or what it's duty cycle rating is. The one linked above appears to be a newer model, but as I said no idea what yours is.
There are also more than a few people that didn't believe the 55mph max speed for the 3 speed trucks with the 6.2l. Some did fine, others destroyed their engines and had to replace them.
Just because you can and it works for you, doesn't mean it's a good idea for everyone.
The rated duty cycle is what it can run without risking failure, usually at it's highest output level which is what will produce the most heat. At lower pressure outputs I'd imagine it can run for a lot longer than what it's rated for without failing, but I'm not going to agree with the advice that the manufacturer's recommendations in the owner's manual can safely be ignored in every situation and every piece of equipment just because another one from the same or a different brand didn't fail.
That being said I have also exceeded duty cycle on some equipment and it didn't fail, but seen other equipment that did fail; some took a long time, others not so long.
Decent comparison from a relatively unbiased youtuber for some popular tire inflators

The reason I posted this on the last page wasn't to use it with their batteries, but to use it with the 24V in the truck.

One thing to keep in mind is there really is a difference between a 20 volt lithium battery power and a 24V automotive system.
That 20V battery is fully charged at 21V, but under load will be operating somewhere around 16-18V
That 24V automotive system will be greater than 25V with the truck off, and 28+ volts running, and it's not going to drop when using the tools.
Not sure how many amps that will draw, but they appear to recommend running it with 2 5 amp hour batteries so I'd imagine it has quite a bit of amperage draw.
I don't expect that the tool will have any issues with the extra voltage during normal running, but do keep in mind the higher voltage will create additional heat that the tool may not be able to dissipate quickly enough for longer operation.
Plenty of guys have made adapters to run 18/20V impact guns off of the truck electrical system, but that is typically short bursts of power, not longer, sustained operation.

there are plenty of 3D printed tool battery adapters out on the market.
Then a smaller slave cable to the slave port, and that's all it takes.

You can disassemble an old battery
For the cost of that, I could get two of the Ridgid units and do two tires at once.
The video I posted above, did an empty truck tire to 80 PSI in 5 mins. Thats not bad. Id be going from about 20 to about 40
