I have not found a better container yet. I don't mind a soft bag, but would prefer one less flimsy and more durable.
Best mobile air compressor unit for Overland travel?

I have a Smitybilt 2781 5.65cfm compressor. It’s not bad, just takes a bit of time to fill up my 37s.
The one thing I didn’t like about it is that it runs continuously vs an ARB that switches off when air is not flowing.
I fixed the problem by adding a pressure switch and wiring it in series with the on/off switch. Oh, and I also changed from the Japanese air coupler to a standard npt type.

I did the same thing with my SB compressor, but I changed the base plate to its side so it fets under the back seat of my Jeep…
I've been using a simple, portable Ryobi p731, 18 volt, LiIon battery operated hi and low pressure inflator deflator. Small, portable, convenient, not too expensive, and runs on the same batteries that the Ryobi portable power tools like circ saw and drill run off. Tops put at 150 psi. 3 year warranty.
Cost about $45 or $50. I used it for 3 years and the air pressure guage would no longer zero out.. started reading 113.5 just standing there. oi can trick it into filling a tire with 35 psi by setting it to 150, but that's about it. Mine was just out of warranty so I had to buy the new p747. The Ryobi rep was there and threw in a double capacity battery and a quick charger.
Maybe someday I'll get a Vaiair, but I dont like needing to connect to the truck battery. I never have to open the hood to use this

I have that same model and have been wanting to do that mod. If you could share more details, that would be much appreciated.
Yes! Let me find the parts I used (somewhere in my Amazon history), draw up a diagram and post it in the DIY section. I’ll post back here when I do.

I have the Smittybuilt also, and use a 2.5 gallon air tank for additional air. Works well and cheap.
This is the cutoff switch I use on my tank. There are many others out there as well. When the tank reaches 100psi the compressor shuts off. This prevents the comp from running too much and overheating.

Nice deal with the 'REP' throwing in the big battery and charger. That made it a great deal. I have had good luck with my Ryobi 18 Volt tools, and actually considered their air pump, but got the Viair 88P on sale instead. Would reconsider that option (P747) if I needed a back-up to my primary. I have 285x75x16 tires, so it would be capable for a 33" tire.
PS: A 3 year warrenty is a excellant addition, given that most items have a 90 day or 1 year coverage limitation, and as has been discussed in numerous threads, air compressor units live a hard life, and see extreme duty cycles, leading to high mortality rates. Probably something those who do not air down all the time would find useful and more or less, least expensive as an addition to their kit.

You can’t really go wrong with most brands. The thing to keep in mind is the operating time (work/rest cycle) and your tire size. The ARB twin is great but you have to factor in the mounting l, which can get expensive. Moreover, they are usually mounted in the engine bay which get dirty and can limit the life of the compressor.
I have the Viair 480p and use the Desert Does It under-seat mount. Keeps the compressor in the cab away from dirt and water.

I previously used a co2 tank, and swapped the Milwaukee m12 inflator. Now that the Milwaukee m18 inflator is out, I have upgraded to the m18 version. I love the lack of cords and pressure settings with memory.

I've previously had the Viair 450c onboard, while not portable the brand did not let me down (They even have new Expedition Line of kits). So much so, Ive got a 480c in a box in the garage that I've not installed yet. I'm actually trying to decide if I make it a portable with some custom bracket/box, or bite the bullet and hardmount it. I do have the ARB twin in my wishlist, just always looking at that price.

Viair 88p. Cheap portable and works good with 33s. Got it on Amazon for like 60 bucks
has anyone used a Sherpa brand compressor? i saw this and it is a bit spendy, but has a max amp draw of 45 amps. thats a pretty substantial motor to take that kind of current. all of the ones i've used were generally around 15 amp

Air armor here, had it for several years now and works fine for inflating my 32" tires. just let it cool down before inflating your buddy's tires too

80 Lbs? What are you hauling? An 18wheeler uses 90lbs in the steer tires to support 12,000 lbs +/- , just curious
