Figured I would review this since I pined for it for so long...

After meeting up with @PhullD in Moab and seeing his 4-tire simultaneous inflation setup, I got pretty jealous. He had it custom made locally. Much later, I found this South African company Indeflate was selling pre-made kits. They sell a 2-tire and a 4-tire setup. Basically, what it allows you to do is connect all 4 (or 2) tires at once so you can simultaneously inflate or deflate them. This also equalizes the pressure between all tires connected. With that last fact, you can do cool stuff like "inflate" a flat tire from a full tire in the event that you don't have your air compressor or something.

The site above unfortunately I think is the only importer of the product (made in South Africa). So when I found it, it was out of stock. I took over 2 months to come back into stock. I bought it the second it became available and it looks like it is out of stock again. The "quick coupler" is needed because the indeflate air chuck doesn't have a quick connect. It's just your regular valve-stem attachment or whatever. So the "quick coupler" is essentially a quick disconnect that attaches to a valve stem.

Now that I've used it several times over the last few weeks. Here are my thoughts:

Pros:

• Equalizes all tire pressures across the board
• Once you figure out how to unpack/repack, it doesn't really feel like any more setup/breakdown work than using a single inflator and hose or deflator
• Super flexible hose, tough quality connections, absolutely no leaking
• PSI gauge seems to be accurate WHILE air is flowing!
• No lever or trigger to hold - just plug it in and let it work
• (totally unplanned) the company colors match my Xterra

Cons:

• Kind of pricey - I can get a decent quality hose, air chuck, and valve stem puller-style deflator for about $60-$90 total
• Learning curve on the uncoiling and re-packing
• Hooking up inflator right to air compressor gets hot when you try to remove it afterwards. I bought a 2 foot hose extension to separate the two
• I haven't had to use this in the mud yet - but I can only imagine trying to deal with it after it has been on the dirty, wet ground

Speed wise, I'd call it a wash between the Indeflate4 and a single air hose. In the end, your compressor is still pushing the same amount of air. Where it saves is that you can plug it in and walk around, play frisbee, stretch, clean up the rest of your gear, etc. while the air takes care of itself. Way better than squatting at each tire and holding the air chuck for what seems like forever, or messing with the valve stem puller. I plug it in and come back some time later and call it good.

So at this point, I would recommend it assuming you don't feel too bad about dropping $200 and assuming that everything holds up for many years.

Now while my tires are inflating, I have more time to relax and enjoy views like this!

After seeing Phil's setup, I built one. You're right you can make one for about $120.

Like you said trying to recoil all the hoses became a pain, so I came up with v2.... a two wheel setup. Now I do one side, then the other, and recoiling it all is a ton easier.
Sure makes A/D and A/U a lot easier.

Nice! This company sells a 2-wheel version as well. I thought about it but I liked the "one and done" concept. I cut my coiling time in half in just a few tries so I don't think the clean up ends up being as bad as it initially seems.

I built my own as well. Cost about $150 but I have tons of connectors and fittings leftover. I only built a 2 wheel version as I thought carrying that much hose around was a little much. I love my setup. Set the front and rear to different pressures. I used quick-disconnects at both valve stems and the connection to the compressor. When I'm not off-roading I use it to set and equalize the pressure on our other cars.

You can make it easier on yourself by coiling over top of the carrying bag so that you know your circles are tight enough to fit. I use those computer cable velcro ties to keep all the hoses together, I can see that being a PITA with stiffer hoses without the ties. I coil one side, then the other and then just stack them after. After 4 years I only had to clean the valve stem quick connectors once. I blew all the material out with a compressor and then used mineral spirits to lube it all up. I guess you can use plastic bags or something and elastics over the ends until you are ready to put them on the stems.

Your compressor will always be the limiting factor. The single ARB like you have is what I have as well. On average I can inflate my tires (315 75R16) from 20 PSI to 37 PSI in about 8 min, but from 15 PSI back to 38 PSI it is more like 12 min. If you had the twin or a CO2 can it would really cut that down a lot.
