good value, reliable.
I air down for beach sand travel in my e450 class C rv with LT225/75/16s. that's 6 tires from 80/65 to 15psi on the way in, and of course, on the way out, it's time to air up for the pavement ride home. I was a bit hesitant to go with a 12v setup like this as all the other guys bring their eu3000s and home pancake compressors to air up. I don't have that kind of storage space so I needed something smaller. It has never cycled on me/over heated given i'm on the beach in the blazing sun most of the time and do 6 tires, not 4. It gets me to 50psi pretty quick - 3 min or so a tire. And i usually do this. Get them all up to 50, so that IF it fails, at least i can hobble my way to a gas station at 20mph and top off there best i can the rest of the way. 80 in 2 and 15 in 4 is not useful. 50-65 and 50-80 take a bit more, about another 3-4 min a piece. The pump has never let me down, but my battery has. I plug into the house battery for the drivers side and use a jump box for the passenger side. This gives me enough juice to get the job done. It's been through several cycles, been in the sand, salty ocean sand, and she hasn't let me down yet. I'm happy with it. I was between this and the viair, but this one was both cheaper and put out more cfm. The gauge isn't accurate- but it's reliably inaccurate. it's like 8 psi off as tested with 2 other gauges. That's fine now that i know it. perhaps the stick just wasn't zero'ed out correctly. know what it is and it's fine. but could surprise someone. maybe it's just mine.

Great 12V compressor
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.

Very good pump.
I have 2 of these. One in my Jeep and another in my pickup. The Jeep unit has seen lots of trouble free usage. I have had air compressors (Viair) that cost over double of these and didn’t work as well. The compressor is great. The fittings and hose isn’t so great. Get a flow through type fitting at the compressor and at the end of your hose. I never have liked those yellow coil hoses. If you are thinking about an air pump this is the one you want. Keep the pump, toss the fittings and hose.

Good But Quirky
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.

Great value for the money
Great pump. It's heavy, and gets HOT, but it should be expected. You can get something smaller if you have SMALLER than 33" tires, but 33's and above you should be using a pump like this when relying on a portable pump for off road. A couple of quick notes to new buyers. 1 - If possible, keep your vehicle running. It'll provide a lot more power for the pump to draw off of, and will work much better (and cooler) 2 - Be CAREFUL after it's been running for a bit. It gets hot enough to burn you if you're not careful. 3 - Turn the pump on BEFORE connecting it to your tire. Says it right there in the manual, and takes stress off the pump when connecting it. 4 - We were able to fill up 6 and a half 35" tires back to back (not turning it off) before it tripped the overheat protection. It took about 10 minutes for it too cool down enough to resume, but it was impressive considering how long it was running. 5 - There are a number of pumps that are identical to this, but are branded differently. One such pump (won't mention the name, but it's red) is both less expensive, and has a uncoiled/straight hose rather than the coiled hose which comes with the smittybilt. I'd opt for that one instead, as the hose is just easier to manage. Regardless, both are great pumps. It's a fantastic pump. I've had a previous one for a couple of years, and recently gifted it to my daughter for her own off-road rig.

5 Star for hand delivered at home for broken part - Discovered pipe tape covering hole
I live near an employee and they hand delivered the replacement part that broke (see image). They said they hadn't seen the part break before. I didn't know about the pipe tape when they stopped by my apartment so I could let them know they should do a quality check. Super nice folks though! I ended up replacing that Japan standard hose fittings with an American standard fitting and hoses. Takes no time at all to air up (IT'S NOT A RACE!). I'd say it takes about 10 minutes from the time I stop, get the air compressor bag out, open the hood, take off the air caps and start airing back up is probably 10-15 minutes. Sometimes I do have to let parts cool down if it's 80 degrees or more outside before I toss the air compressor back in the bag. When I took the Smittybilt factory Japanese fitting off, I noticed pipe tape was covering the opening (see image). The factory gauge on this air compressor is a complete joke and worthless. If you use it, figure out where the pressure is by airing up and keep checking. Then track what the air pressure shows on the pump. Here are my air up notes: 2020 4Runner TRD Off Road Smittybilt 2781 gauge is worthless 32 PSI on Smittybilt = 35 PSI on dash computer 31 = 34 dash 10 = 20 dash Pump air ON Smittybilt compressor to read 42 1/2 PSI on gauge TO GET to ~34 PSI on DASH then take air out to get to PSI for ambient - This was never really consistent at all. I ended up abandoning this method. So what I do now (after I replaced the factory fitting, gauge, hoses and air nozzle) Hookup the Smittybilt power leads to the battery and close the hood while watching out for the power cables from getting smashed (you don't have to slam the hood, you just have to get the sensor to trigger the hood is closed). What's my tire pressure supposed to be at? My 4runner door jamb label says tires should be 32 PSI at rest ambient temperature. Meaning tires are not hot from driving on the road and whatever the ambient temperature is. At 10 degrees ambient temp tires are at 32 PSI. 120 degrees ambient temp tires are at 32 PSI. However, if you're at 32 PSI in 120 degrees and drive to where it's 10 degrees, your tire pressure will be 21 PSI when the tires reach ambient temperature when they cool off from the road friction. I close all doors with the drivers side window open all the way. Reach through the window and change the gauge cluster to show TPMS (cluster will switch back to something else if ANY door / hood is open) and air up to when it reads 31 PSI on the dash. By the time you get back to the air compressor and turn it off, it'll hit 32 PSI. 1 PSI is added from the time I see the dash change to when I get to the power switch on the air pump. TPMS rounds PSI up and down. 31.6 PSI is 32 PSI on the gauge cluster and 32.4 is 32 PSI on the dash. It's really not rocket science but if you can get within 2 PSI on all 4 tires, that's optimal. You can always add or remove air, but be mindful of the ambient air temperature and allow 1 PSI per 10 degrees of ambient air temperature. And whether you're going to drive to hotter or cooler places.

Super fast and well built
This thing is fast! After researching portable air compressors for a week, I noticed that this was consistently at the top of everyone’s list. After using it for nearly a week at the Outer Banks in North Carolina, I can see why. It was able to air up my pickup tires from 20 psi to 40 psi and someone else’s next to me from 18 psi to 50 psi without stopping. That’s pretty impressive! Was it hot? Well yeah, a little but not so hot that it couldn’t go back in the carrying bag. I’m impressed and very glad with my purchase, it’s a beast. This was an extreme use case airing up 8 tires without stopping and it stood up. The pump does require alligator style clamps that hook up to your battery so you’ll have to pop your hood every time you want to use it. While researching these compressors I noticed that if you want more power and fast performance, you’ll have to go with alligator clamps. Not convenient, but necessary for the type of power I was looking for. It’s solidly built and I got more than I paid for it.

Nice little compressor
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.
