SmittyBilt AIR COMPRESSOR 5.65CFM - SB2781

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.

This pump has plenty of power, but run your vehicle while using it for best performance. The pump generates lots of heat especially at the hose fittings, so No Toucha Da Hot Parts! It was 42F out when I tested mine and you can see the fitting temp after 1 tire. I drained my 35" SSR flat, reinstalled the valve core and pumped it up very quickly. I do not believe it was more than 2 min to get to 50psi then drain back to 35psi. What I do not like is the crappy bag. It could be a bit heavier material and have at least a tab if velcro to keep the accessory pocket secure. That may sound whiny, but if you have one you know. Also, I can live with the non-typical air chuck fittings, but not the air chuck which is of very nice quality, but has a straight screw on tip. This makes you bend your alve stem outward and does not allow for quick on and off. A simple.lever lock quick chuck found on most bike pumps would be a great upgrade. In my opinion this is all the pump you need unless you have air locker rears. If your trip requires many air up and downs, a CO2 tank is your best choice.

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.

the attachment with the in-line gauge is NOT accurate, it's off by a few-degrees (~2-3PSI +/-1). I must confess that my reference point was the digital gauge of the vehicle (2021 F-250) monitors, aka the tire-pressure sensors but yeah, there's a disparity of about 3-psi. Not sure how I feel about that. The motor and pump themselves are great. I also don't like the plumbing connectors for the quick-detach couplers on the hoses that ship with the pump. Otherwise, it works amazingly compared to a traditional tank-filled compressor (this is tankless) and it has no issues with heavy-duty tires, doesn't even break a sweat reaching PSI levels above 70-psi. The directly-attached hose does get hot but that's expected for compressed air plumbing--I just wonder if the materials of the hose can expect durability because of the heat stress. I really don't like the fittings, I don't think they use standard quick-detach adapters so you could easily swap for off-the-shelf parts but all in all--it serves its purpose and does so rather well, except the aforementioned grumblings. I still give it a solid 4.5--so that's a statement for this insatiable consumer with high demands for his dollar investments.

Son loves it for airing up tires in his truck after off-roading. This is a good brand that I have purchased from before for other items. Long lasting and reliable.

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.

The first one we got had a crimped hose, but Amazon quickly and easily replaced the item. The pump works great. Inflates from 20 PSI to 37 PSI fairly quickly compared to what others are using. But it gets HOT. When we are done inflating we don't put it back in the bag immediately. Also the bag that it comes with is a very thin, light weight. We ended up getting a different bag that holds the pump and a few other items so it is all in one place. Overall I am very happy with this pump and have even used it to inflate giant pool toys and my bike tires.

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.

El producto está buenísimo, aunque la manguera de inflado se ve de baja calidad. El tiempo de inflado por llanta es de no más de 2 minutos, muy buena opción

I inflated a normal SUV tire from 0 psi to 35 in 2 minutes 30 seconds < shall i say more. downside, it gets a bit hot so handle with the HANDLE.

J'ai acheté ce compresseur pour remplacer mon ancien que je me suis fait voler. J'ai été très satisfait du premier, et je suis très satisfait de celui-ci. Lorsque nous faisons du hors-route, nous devons dégonfler nos pneus pour une meilleure adhérence. Avec ce compresseur, je regonflais rapidement mes pneus. Souvent, j'avais fini de regonfler mes 4 pneus et les autres personnes, ayant des compresseurs qu'on retrouve en grande surface, en étaient rendues à commencer leurs 2e. Un truc pour la pleine puissance du compresseur, laisser le moteur du véhicule en marche lors de son utilisation.

Es super rapido y resistente, lo probé en llantas muy grandes de 42" y las infla en menos de 2 minutos cuando los compresores pequeños tardan hasta 10 minutos, lo unico que no me gusta es que los conectores de las mangueras son tipo japones y no son compatibles con los tipo americano que se usan aqui pero es un gran producto

Works great getting tires on my truck back on the rim and filled up quick while out 4X4ing in the back country. Fills the larger truck tires very quickly. Worth the cost!!!
