ALL-TOPAir 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

Very fast. 35” tires inflated from 18 PSI to 38 PSI in a few minutes. The tire pressure gauge is not accurate at all. The gauge does have a deflator valve which is very convenient though. The included hose is sturdy. Overall, good product that saved a lot of time filling up my tires after an off road trip.

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 purchased this product from Amazon and I am not compensated in any way for this review. My overall impression of the compressor is positive. It is powerful and inflated my RV tires to 80 psi. A buyer should understand this is not like compressor that stores air and recharges when it gets below a certain level. Instead it pumps the necessary pressure into a tire from the surrounding air. I have easy access to my RV battery so I don't have any issues with cord length. The hose length is more than adequate as well.The air coming out of the compressor gets really hot. Also, the compressor surface can burn you even if it was used for a minute or two. The compressor should be given some time to cool before putting it away in a bag or RV storage area.The gauge is not as accurate as I hoped. I believe you need to turn off the air compressor to get the true tire PSI otherwise the gauge will read the higher incoming pressure. I need look into that further. I will probably get a more accurate gauge at some point, but it's close enough for now.The pressure release valve was not installed tightly to the compressor, but I was able to tighten it by removing the pull ring and red cover. The nut was easily accessible to make the adjustment.Overall I have to give this four stars with one star knocked off because of the cheap gauge and loose pressure release valve, but neither were deal breakers for me. For a compressor in this price range, I give it two thumbs up.

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.
