A brand new owner of a 2020 ORP here... I need recommendations for a portable compressor and air down gauge, something that doesn't break the bank.
thanks

Vlair 88 is what i used before going vehicle mount, that thing was a workhorse. As for air down gauge, i have fancy ones, but now use a 1 dollar stick reader type from the local gas station.

Yes, thanks. Some folks on youtube were recommending this but some reviewers were complaining of long times especially for tires 3&4, did you see that?

I’ve been using the smittybilt 2781 and have been very happy. Fills tires up very quickly. The one “issue” is that it uses Japanese style air fittings so nothing else will fit on it. I knew this and just planned to change it over which was also easy to do.

For air down I like the screw on pre-set style myself. I’ve got 2 sets in the truck, 4 are set to 18psi and 4 are set to 22psi.

VIAIR - 40045 400P-Automatic Function Portable Compressor

I paid $217 before tax in 2018

all single compressors are slow as heck and you have to wait a little bit for them to cool down before putting them away.

I have the twin ARB compressor. A little on the pricey side, but it has worked great. And it's pretty easy to find a mount that lets you put it in the engine bay. Airing up all 4 tires (combined 80 PSI increase) takes around 5 minutes.

As far as deflators go... I have an EZ deflate gauge (also from ARB), but I don't ever use it. Like someone above said, the stick reader is quick and simple.

For portable, my Viair 400P has been great. No complaints, but I would mount an ARB in the engine bay if I were to do it over again.

The Smittybilt 2781 is 5.65 CFM single. The ARB twin is 6.05 CFM. I think the ARB would be around 3-5 seconds faster per tire. So they're pretty close. Take around 2 minutes per tire to fill. I'm sure the ARB is probably a better quality unit. But my Smittybuilt has lasted quite a while.

There are some faster ones if you want something a bit more $ and more "exotic" like the sherpa big-air.

The price on the smittybuilt is really the biggest selling point. It's $150. Mine is around 4 years old now. Has filled hundreds of tires. Works great.

The most common issue I've had airing up/down is just dropping a valve core in the snow or mud. If you're going it a lot - buy a spare valve core or two and toss them in the compressor bag or somewhere you won't lose them. You can steal one out of the spare tire in a pinch, but they're cheap and easy to keep in a spare parts bag.

Also if you're new to this - you need a tool to remove the valve core to air down. You can do it with a deflator tool - but it takes forever. It's easy with a valve core removal tool and the valves Toyota uses whistle at two distinct pitches at around 18psi and 15psi. Once you do it a few times you can air down by ear and get pretty consistent final psi just by listening.

For deflators, I use these. Amazon.com: TeraFlex 4807200 Air Deflator: Automotive
They are cheap, hands free, have no adjustment to worry about, and are easy to store. Comes with 4 of them, and you can just screw them on the valve stem and walk away. If you work out the timing, you should be able to walk around and screw one on each tire and by the time you're back to the first tire it should be deflated to near where you want it. If you just do one at a time it's not any faster than sticking a key onto the valve stem perhaps, but at least you don't have to crouch there while it deflates. Also, a pressure gauge fits on the end of them so you can easily check pressure as they air down.

I've got the Viair 88P and find it works great for the price. Amazon.com: Viair 00088 88P Portable Air Compressor: Automotive

Airs up my stock size tires from ~22 to 32 PSI in probably a minute or two each at the most.

I like that it has a gauge on the pump next to the power switch so you can easily turn the pump off while filling to check pressure. I like that it has a soft and flexible air hose. I like that the hose and power leads are quite long. And I like that it has a screw on air fitting instead of one of those lever types.

The ONLY complaint I really have is that it gets quite after filling them all, so I don't put it back in the carry bag right away until it cools off so as not to melt the hose or power wires.

I use Viair 300P... it's quick!

Thanks everybody for the great advice.

Mine has been great. Under 90 seconds for each tire.... 18-40psi and not too warm to put away....

For about 8 years I used a Superflow MV-50 (Currently about $100). It wasn't fast but it lasted forever. On it's last day it aired up my rig and three others before it died. It seems they got expensive since I originally bought it and there are better alternatives now like the Smittybuilt. I now use a hard mounted Viair 400H and it's great so I'd recommend a Viair if it fits your budget.
As far as airing down goes I use Currie EZ Deflator which is great. It seems ARB may have purchased Currie. If you're using this type of deflator definitely carry some extra valve stems as was indicated earlier
