ALL-TOP Air Compressor Kit, 12V Portable Inflator 7.06CFM, Offroad Air Compressor for Truck ,Air Pump for Car Heavy Duty, Max 150PSI for SUV 4x4 Vehicle RV Tire

I like to go offroading which means I air down my tires and need to air them back up. Before buying this compressor I have owned a Harbor Freight branded one, and some generic no name unit, both of which failed within the first 3 trips. I am not a super serious offroader. I go on a trip about once a month. So far this has been the best 12v compressor I have ever owned. I used it 3 times at home before taking it on an offroading trip in Moab, UT with 3 of my buddies. We aired up and down twice and the All Top handled it like a champ. It did get warm around the compressor output, but that's just physics, and it never skipped a beat. The compressor seems to be fairly well built. It is definitely heavier than its competition, but I don't think it is quite the quality of something from ARB, but I have never owned one. The power lead on the compressor is a good length for my use case, which is a slightly lifted midsize SUV. I usually put the compressor on the ground, run the power cable up to my battery, and reach all the tires with the hose. If you had a monster truck I think you would need to leave the compressor in the engine bay or get something to put the compressor on to raise it up. The hose is a good length but the gauge on it is basically useless. Id rather it just have nothing to be honest. The accessory bag includes a few useful goodies. It has a quick disconnect for air up tires, a few nozzles for blowing up balls or inflatable pools, and an adapter that will allow you to hook standard air tools to the non standard quick connect this compressor uses. Generally when I fill up my tires I use the gauge on the hose to guesstimate what pressure the tire is actually at, disconnect the hose, and check it with a second gauge. I guess you could attach one of those tire inflators with the air tool adapter but this method works fine for me.

The following is based on 265/75 R16 BF Goodrich KO2 tires 10 ply rated. I could deflate one tire from 40 psi to 20 psi in 28 seconds with my ARB valve core removing deflation tool. Then, I could reinflate the tire from 20 psi to 40 psi in 1 minute and 36 seconds with this All Top compressor. I see no need for two or four tire inflation systems at this rate and simplicity. I simply do not 4wheel enough to carry that extra bulk. The analog gauge on the All Top matched the analog gauge on the ARB deflator. I also used a traditional tire gauge and it also matched the other two so accuracy seems reliable. The build quality of this pump is high. The heavy duty rubber pressure hose has a high quality feel and is more than enough to reach the most distant tire on my Toyota Tacoma Double Cab Short Bed pickup. The power switch has a built in dust cover. The pump fills the tires so fast, worrying about overheating etc. is unnecessary. Ambient temp was 95 F when filled 2 tires for my test and the pump was warm (this is the normal operation condition) but far from hot. All supplied items in the zippered case weigh 19.4 pounds. It is not light, odd that this is part of the star rating, to me it indicates a robust build and I did not lower its rating for this. This is not a light duty compressor for a commuter car. It would work but would be overkill! The kit came with an adapter to downsize the output connector to a 1/4 inch connector (common for other air tools and hoses) so versatility is included. Also, the end of the pressure hose is a twist on connector for the tire valve but there is another adapter that fits on this and makes it a quick connect/release to the valve stem. The quick release adapter stayed in place without fail and sealed appropriately. The battery terminal clamps are robust and feel like they would last forever. This is my first high quality air compressor and it has impressed me with its quality and speed. I would highly recommend this as it seems like a sweet spot for quality VS price. Hope this was helpful!

I ordered this and used it for the first time today. It topped off my RV tires to 80psi in a matter of seconds (added about 5 psi). So that wasn't a major test really but worked fine. As others mentioned, it's a bit on the heavy side but not overly so and that's probably a good thing. It has various adapters for the hose and to fill various items. The hose has a screw on type connector and there's another adapter that is for quick connect/disconnect (5th picture). The quick connect adapter is more useful. By using that you can have the compressor on and remove it to check the pressure with a separate gauge. The attached gauge is ok but you have to turn the compressor off to get a reading. It's easier to just take the hose off and check while the compressor is running. Otherwise, you would have to go back and forth to the compressor and turn it off/on. There is also an adapter with an Industrial style coupler (4th picture) for use with other types of hoses. The connector on the compressor itself and the hoses appear to be some custom/proprietary style which I found odd. I would think it would be less expensive for them to have a standard coupler. That way you wouldn't need another adapter to connect with industry standard couplers. I did use the adapter and attached my own hose. This worked fine except that if you use a typical tire inflator it will build pressure in the hose and pop the pressure relief valve on the compressor. So while the ability to connect standard hoses is handy, it's not super helpful if you're airing up tires. The hose is decent length and seems to be decent quality. It doesn't seem cheap. But it's also not the same grade of hose you'd have on a typical compressor (I wasn't expecting that anyway) My hose leaked where the gauge screws in. I removed it an added some teflon tape. That sealed it up. The deflator valve doesn't work on mine. When I removed the gauge, the deflator would push in. With the gauge installed you can't push the deflator in.

Bought this unit specifically for my motorhome. Rated at 150psi, has industrial air fittings, auto shut off and it will run for about 30 or 40 minutes with a constant flow rate of around 40PSI. Perfect for blowing out water lines, airing tires, and supplying compressed air for whatever maintenance needs wherever you are. I may permanently mount it somewhere on the rig. Just like having a nice air compressor in your garage. You use it a lot more then you ever think you would. Will not travel in rig without it.

I finally got to try this after months of looking at it in the back of the Jeep. A friend had a pickup truck with 245/75r15 tires three were down one with 20 # I left the first one on too long, it was 50 # when I moved it to the next tire! Only a few minutes had them at 35 psi. The overheat switch never did anything. Four truck tires without stopping, compressor ran constantly The clip on the valve stem worked very well, the pressure gage was the only thing, it was I think showing the pressure of the hose not the tire (50#). A simple pressure gage told me what it was, maybe shutting off the compressor, too far away, would have accurately told the tire pressure. (After use, the gage on the hose WAS the or assure in the tire) After I shut it off the hose at the pump was hot not terrible, as I had gloves on, and the handle never gave a clue, I still waited some time before placing it back in the bag.. Very pleased.

Works great. Mine gets really hot, to the point I need gloves to take the air hose off. I don’t know if that’s common, but that’s the only fault I see in it.

After airing up two 33" tires (from 9psi to 19psi) after a week of wheeling the on/off switch no longer worked. Thankfully it was stuck in the ON position, so I used the alligator clamps on the battery terminal as the On/Off switch. Then the included fill hose adapter pops off the barbed nipple under the load of the air compressor on the third tire. Used some pliers to keep the hose on and someone else to control the new On/Off system. Happened after the 30-day Amazon return timeline so it now a good looking, fast filling compressor, that doesn't work. The first two tires filled quickly compared to my older smaller compressor that is over 12-years old and still working. It's heavy and bulky but that's what's needed to fill quickly. Buy at your own risk. Maybe I got a lemon. This seems identical to other compressors for more money, maybe they used the extra money on a higher quality On/Off switch and a better hose connection. Strongly suggest you look elsewhere. Follow-up after repairs: I initially thought there was something wrong with the switch and purchased a replacement. After disassembly the housing I realized what happened to have the compressor not turn off. The interior of the switch and power entry housing is tight and the the problem was associated with the wiring, not the switch. All connections were soldered but not all of the connections were well protected. With the natural vibration of the unit, combined with the tight quarters created, a short. The hot into the unit essentially bypassed the switch when its unprotected conductors were touching the exposed blade of the switch. I did a little surgery, put on proper end connectors on, fully isolated the wiring and exposed conductors and no longer had the "I can't turn it off" issue. I also found a Japanese style quick connect adaptor to US style connectors and no longer need to use the poorly connected adaptor that came with the unit. Other than spending more money on the quick connector adaptor, if you are remotely handy, you can repair the On/Off switch not turning off if you pay a little more attention to the details than the manufacture did.

Got this during Prime day so I got a killer deal on it. So far I've used it twice now without issue. It's quick. It brought my 265/70R16's from 20 to 35 lbs in about 50 seconds (well...I counted to 50). In case you missed it. This thing has a non-standard quick connect fitting on the handle. That fitting matches the long hose that's provided. But, what's really nice is that they provide a small bit of hose that converts it from their non-standard fitting (European fitting?) to the 'Industrial D' style fitting that's so popular hear in the USA. There's also a couple other fittings and converters. couple notes. It's not small. This is larger than your average car tire compressor. That's why it's fast. It's also not that light. But again, do you want to blow up balloons or your tire? This thing does get hot. The compressor piston area was hot to the touch as was the output. There's warnings about it and they don't lie. Now, a couple niggles - The gauge is at the end where you fill the tire, but the ON/OFF switch is back at the pump. So you can't easily check the pressure while filling it. You have to fill it for a while, turn it off, walk over to the gauge, then turn it back on, and repeat until done. If the designers were thinking, they would have put the gauge on the device or near the end that connects to the device. - The gauge seems to be a bit inaccurate when comparing to the tire pressure sensors. I filled all tires to the gauge said it was 35psi. The TPMS for each tire reports 33-34psi. - There's no auto shutoff switch. - The alligator clips are kind of small and the cable gets warm. The future: - I'll probably build up a 4-tire inflation/deflation kit and include a more accurate gauge as well as a ball valve so I can stop the flow and check the pressure. But to do that, you need a pressure switch so you don't damage the compressor. Therefore... - I'll probably hard wire in a pressure switch to automatically turn off the unit when the pressure gets high. - I might rewire the power cables. The ones provided seem to get warm and the alligator clamps are kind of small and barely get around my battery posts. - I might remove that non-standard fitting, retap the hole to 1/4 NPT and install a Industrial D fitting on the unit (but that's only if I do the first item above). - For all the above, the 'U-toob' has several folks that have done those modifications to increase the capability of these compressors. There are several with different branding that are just like this unit.
