SmittybiltAIR COMPRESSOR 5.65CFM - SB2781

Nice compressor, I was going to get an arb twin but could not afford it at this time, so I got this for now. I have 34" tires and it airs them up pretty fast. The battery clips are a bit small but will clip on the battery bolts and work just fine. It dose get pretty warm but cools off quick. The pressuer gauge is not that acuret but i compaird it to another tire gauge and just remeber where i need it to be. I would definitely recommend this compressor for the price build quality and speed.

Pretty happy with this compressor so far. Have only had it a short time. Will air up a 235/75/15 tire on my Jeep ZJ from zero to 30 pounds in a little over 30 seconds. On my Suburban K2500, it will air up a 305/70/16 from 22 to 50 pounds in 2.5 minutes. Best speed of any 12 volt compressor I have seen. Definitely not as fast as my CO2 bottle but a lot better than my old 12V compressor. It took about 2 days to fill up the Jeep tire. This one comes with a short run of rubber hose that connects to the compressor, between it and the plastic coiled hose. This rubber hose gets very hot and I wonder how long it will last, probably should have been a length of steel braided hose instead. Have not had it to the beach yet to see how it handles airing up 4 tires on the Suburban but suspect it will do fine. Looks to be quality construction, not cheapo looking. Comes with a handy carrying case that holds the compressor & hoses easily. I will probably add a coil of copper tubing at the discharge to act as an after-cooler so the hoses don't get subjected to so much heat. The cylinder itself barely got warm, just the discharge hose got hot. I also like the black finish as this tends to reject heat better than other colors, especially the chrome plated ones. Definitely worth the money in my opinion.

I keep this in my truck at all times. There are times I need to air down and it's great to have on hand when I'm back on dry pavement. I run 70 psi in my tires on the regular and this thing does that with no issue. It does get hot while it's working so just keep that in mind. It works relatively fast. It has a long power cord and a long air hose. I can attach it to the battery terminal in my truck and fill the back tires with no problem. It's a little pricey but I like having it in the truck!

tl;dr: Good compressor with nonstandard fittings, adequate accessories.I have been using this compressor to air up my Jeep's tires for two weeks. It does a fine job of pumping air into the tires, although after running for a while the hose gets very hot (too hot to hold for even half a second, not hot enough to cause instant burns when touching for a moment). The heat is acceptable, although it means I can't put the compressor away in the supplied carrying bag right away.I'm using an octopus rig with an attached pressure gauge to air up all four tires at once. I haven't yet timed how long it takes to air up my 31" tires, but it doesn't feel long at all. I like the octopus, and I like the pump, but the disappointing quirk is that the compressor has unusual fittings and won't fit any of the available air line connectors. To use my octopus rig, I had to cut off the Smittybilt connectors and install ones that fit the rest of my gear (1/4" industrial/Milton). I wouldn't have minded if they'd used automotive connectors, but the Smittybilt ones are not compatible with anything I could find in the local stores here in Southern California.The accessories are decent, but nothing special. The carrying bag fits everything easily, and can even carry a little extra (spare Schrader valves, hose repair tape, etc.), but is made of fairly thin fabric that doesn't look like it will stand up to hard use. The carrying handles are sewn on to the sides instead of wrapping around beneath, and the interior pocket collapses so readily that it's almost as if it isn't there. The coiled hose, with the odd Smittybilt connectors, is fine but too narrow and restricts the air flow a little. The air chuck and pressure gauge is probably good enough for occasional use. I plan to rely on the octopus, but I'm happy to carry the Smittybilt chuck/gauge as a spare.I can't really rate the longevity of this compressor after only two weeks of use, and plan to update this review once I've used the compressor for a while.

This compressor really does the job. I can air down and re-inflate my 37 inch AT tires in minutes. The carry bag is falling apart, though; could have been made with a more durable material

This is a great little compressor. I bought it primarily to inflate 31” Jeep tires after airing down, which is an easy task for it. Most decent 12V compressors would have no issues bringing 31s from the low teens up to 30 PSI and this one does it quickly and easily, and at a great price point. However, the really impressive thing about this compressor is how it handles higher pressure tires. I run 33” tires (285/75/R16) on my 3/4 ton HD pickup and like to “air down” to the 25-30 PSI range on occasion. This compressor is able to quickly bring the pressure in those tires up to 50-60 PSI. I haven’t timed it, but it’s quick enough.Overall this compressor is a great buy. My only compliant, like others, is the proprietary air fittings. I would prefer to use a standard air chuck at times, but the included inflator/gauge works well enough that I haven’t attempted to modify the Smittybilt fittings. The gauge isn’t very accurate while filling the tires (typical of inline pressure gauges while inflating), but it will get you close enough if you remember the offset (usually reads about 5 PSI high while inflating for me). I bring a separate tire pressure to verify.
