ALL-TOP 12V Air Compressor w/LCD Control Panel to Preset Target Pressure, 150PSI 12.35CFM Air Pump Inflator for Overland (Dual Cylinder)

Well, I just received this Alltop twin cylinder 12VDC compressor. The packaging was great. It was actually triple boxed. It's own box with pictures and descriptions. Then a "packing" box with styrofoam. Then Amazons box. So, I was fairly assured the unit would be in great shape when "un boxed". While the compressor does come with it's own air fittings, they are industry standard fittings. So, it's quite possible that your home air tools, i.e. blow guns, extension hoses etc. will work. It all depends on what kind you have.As for performance. Well, here's a down to earth test. WE run 315 70 17's on our 2015 Jeep JKUR. When it comes to trail tire pressure, I've been running 10 psi for decades and have never had any issues. So, for this test, I bled one of my 315's (basically the same exact tire as a 35" tire) down to 10 psi. I then connected the compressor to the Jeeps battery and the hose to the tire valve. I started both the compressor and my phone's stop watch at the same exact time. Not knowing what kind of exact pressure is in the tire at any given time, which has been stated by many on here, I gave this compressor ONE MINUTE of pumping before I hit the power button on it to stop it.With the Jeep engine running, that gave the compressor full voltage to use while pumping. At the end of one full minute of pumping, my 315 had been inflated from 10 psi to 25 psi. So far, so good. So, I bled that tire down again to 10 psi. I reset my phones stop watch and then, hit the power button on the compressor and the phone. This time I gave that compressor 1 minute and 15 seconds. At the end of that session, that 315 was sitting at 31 psi which, is my street pressure. Soooooo, with all that being said, at this time, I'm pretty darn happy with its performance. It is a tad LOUD but, what 12V compressor isn't!!! I had a Viair 400P before this and that compressor would take 2 minutes and 45 seconds to air my 315 from 10 psi to 30 psi.I'm not one for lolly gagging around at the end of a trail day. I just like to air up efficiently and then head on back to camp or home or ? THEN I can relax. So, this compressor is about as fast in airing up a 315 from the low pressure of 10 psi to my street pressure of 30-31 as you can get for a 12V compressor. And for the money, I think it's well worth it. The CFM on this compressor is over twice as much as a SB one and it's only $3.00 more so, WHY NOT!11/21/23 edit:I've received some repetitive questions on this little compressor so, I thought I'd take a minute to answer to the general public just in case they're thinking of this unit. The question that's been asked more than a few times is: "Will this compressor shut off when it reaches it's max pressure"? NO, IT WILL NOT! To the best of my knowledge, none of these 12V compressors have a built in pressure switch. But, I've not bought them all so, I really don't know. I do know that the All Top didn't.So, here's the mods I did to this compressor to accomplish a few goals.1. These compressors, like ALL 12V compressors, will get extremely hot when used to pump air back into todays large jeep/truck tires for street pressure. If you don't think they get hot, you're mistaken. ALL compressors build heat when compressing air, it's a given. That's why all your commercial compressors used *finned* supply lines from the compressor heads to the tanks. Soooo, I added THREE computer cooling fans. One for each cylinder/head and one for the center manifold. Those fans are hard wired into the power plug. They come on immediately when the power is plugged into the compressor.2. Since these compressors have no regulation to automatically shut off at a given pressure, I added a pressure switch. It cuts in at 85 psi and cuts out at 100. I installed it right in the rectangular manifold.3. I completely discarded the printed circuit board that comes with the unit and wired in my own 125 amp relay to handle the large current required for turn-on and turn-off.4. I added a small toggle switch to control the power to the pressure switch.5. I also discarded that junk power cord that was permanently attached to it. Some may like it but I was not a fan of that cord.6. In place of that cord, I installed an Anderson SY-50 connector and bolted it right to the cage of it. To power the unit, I build my own 6' power cord from Stinger brand ultra-flexible 4 gauge wire/cable. This wire/cable is so flexible it's like a fully cooked spaghetti noodle! I installed Anderson SY-50 connectors at both ends. One is for the compressor and the other is for plugging in to a mounted SY-50 connector on the front of our Jeep. I don't even have to lift the hood to get this compressor going.7. I was not a fan of that little short hose that was permanently attached to the manifold. So, I removed it and drilled and re-tapped it for a standard quick release fitting that many of us use at home etc.So now, instead of burning that new little compressor up each time I stop to check pressure, that unit stops dead on its own. I plug in that 6' power cord to it, the three 70mm x 15mm computer cooling fans automatically turn on, then I turn on the little toggle switch, the compressor runs for approximately 1/2 to 1 second and auto-shuts down. I then break out my Flexilla 25' flexible air hose and connect it to the compressor. Again, that compressor runs for approximately 1-3 seconds to fill that air hose and then shuts off.When I begin to fill a tire, I give it around one full minute to get about 90% of what's needed for street pressure then release the trigger on the air chuck. Within approximately 2 seconds, that compressor shuts off! I then give it about 15-20 more seconds to reach my particular desired street pressure of 30 psi and at that time, the compressor shuts off. All the while, those fans are running and blowing air directly onto those heated cylinders and heads and manifold. Waaaaaaay better than just letting ambient air try and cool it down.By the way, all those components/parts that I added, really didn't ad any bulk or any appreciable exterior measurements. It's almost as compact (if ya wanna call this one a compact compressor) as it was from the factory. Now, one more thing. OBVIOUSLY, since I did a zillion modifications to this unit, I threw the warranty right out the window! If this little compressor goes up in flames tomorrow after owning for a month and only using it for one or two times, then it's all on me. I eat it. But, to me, the modifications and the ultra beneficial results of auto-off-on, the fans, the elimination of that junk power cord and more, were/are worth it. I'd do it again in a heartbeat!

Absolutely love this compressor. Works very well. Fills up my 37s on my Jeep within minutes. It's compact enough to keep in the Jeep at all times. It is loud but most are. Great air flow. Does get hot so be careful.

She's a beast. Got a little weight to it. Which is what you want. This thing puts the slime brand units so far to shame they don't know what they are anymore. ha ha. Shorter power cord (best that way) long hose with gauge and a backwards mounted coupler. If I do anything different to it I will just get an air hose mender and put regular couplers on it. Gauge reads about 5 psi high. Suggest checking your own from a known trustworthy gauge to be sure. It's pretty easy to set up. Kinda loud (also a good sign for a compressor), as far as I know it isn't pressure switched. Only on/off and I'm assuming thermal protection, so don't leave unattended while inflating. It boasted a lot of cool stuff. And it delivered. For a mobile emergency or multipurpose compressor, it is more than I ever had before. Big alligator clips because it requires 90amp DC. That's impressive in my opinion. I also added a good flat repair kit in the bag with the compressor unit.

The media could not be loaded. Exactly what I needed for off roading. I run 35x12.5x17’s on my JKU & usually deflate to 20 psi. This compressor can get each of my tires to highway pressure (35 psi) in about 2 minutes. From set up to filling 4 tires to put away took about 20 minutes.My biggest complaint is the in line pressure gauge is pretty much useless (cost one star) it won’t read the pressure while you’re filling the tires, you either have to disconnect the hose to get a reading or shut the compressor off.There are a couple of other very minor like the battery clamps are a little tricky on my battery post connectors (see my video) but I figured out a couple tricks to make them work.It is much bigger & much heavier than I was expecting (don’t plan on hard mounting this under the hood or your seats) & I doubt the carry bag will last more than 2 trips.Other than that, it seems to be sturdily built, works well so far & is far less expensive than the smaller off road compressors being offered at the 4x4 shops.If your needing portable compressor to air back up at the end of the trail but then this should work just fine.

Love this compressor.We are occasional off roaders 32”s on a Jeep. We air down play and this gets us ready for the HWY’s fast. Used it for about 23 trips so far. It moves an excellent volume of air and I am very happy with it!

The media could not be loaded. I finally got a chance to use this. It works GREAT. Super simple to use and aired up the tires on my Jeep from 12 to 41 psi quicker than expected. Easy-to-see LCD display, simple interface and quality parts. Air hose is long enough to easily reach all 4 tires. Easy grab handle on top and the battery connection clamps feel pretty solid.It does get a bit hot when I have to do all 4 tires after a day of off-roading. But I just put it in the back and let it cool off for a bit before putting it back in the bag.Very happy with this purchase!

I was a little hesitant just because I’ve never seen a very good 12V compressor. This thing is pretty awesome! First time I used it I hooked it up to a flat tire on a dump trailer. Set it to 95 psi, turned it on and in a couple of minutes it had it pumped up to 95psi, no problem!

This air compressor is a game-changer! Fast, durable, and perfect for trucks/RVs. Handles 150 PSI with ease. Highly recommend for off-road adventures—worth every penny!
