I received this in good time on Oct 20th and used it that afternoon as the front right tire was reported to be low at 27 psi. I set the max psi on the inflator gauge to tire manufacturer recommended 33 psi, attached the air hose to the tire and turned on the inflator. It quickly filled the tire to the 33 psi on the digital gauge but then did not auto shut-off. OK, let me clarify: the air stopped going into the tire but the pump itself kept running. If that is what they mean by "auto shut-off" then, OK, it worked as advertised. Next I decided to put air in the other three tires as well as they, too, were low. Set those to 33 psi as well. When finished I started the car and using my dash to check the tires, they were off (low) anywhere from 1-3 psi. None of my tires was actually showing 33 psi. Then I got my manual tire gauge and checked each tire and, as reported by my cars dash panel, they were all off by 1-3 psi, even though the psi was set to 33 on the pump. In theory all four tires should have been at 33 psi but they were not. I don't know if I missed something in the instructions or not but overall gave this 4 stars because the tires did not get inflated to the set 33 psi. Easy to use: 5 stars. Easy to read: 5 stars. Accuracy: 4 stars. Overall rating: 4 stars.

Not so fast but good

The media could not be loaded. I have had many 12V compressors over the years. All of them were horrible, but they were cheap. I was tempted to never buy one again and just get a large one in my garage, but I really wanted a good mobile compressor that worked and was compact. I did a lot of research on the best available compressors and then I came across this one. I had this in my cart for quite some time. I read and reread the reviews. Compared its claimed abilities with others. Then decided to pull the trigger. My biggest concern was will it actually be able to hit 150 PSI. Many claim they can but will burn up before they get there. I read some reviews that said it will easily hit 80PSI which is the max I needed.

See my video. It reaches 80 PSI and without Issue. I got this for my trailer and my truck which both have PSI between 60 and 80PSI. So far I really like this compressor. It had the highest run time at 20 minutes where not others were 8-12 minutes. It's good to have the higher run time when you need to get to 80PSI.

They explain that you need to set the PSI 1-1.5 lbs higher than you want. This is true. 2lbs when you get up to 80PSI. I tested the pressure with a gage and at 80PSI, it was about 2PSI low. I was pretty fast at taking the nozzle off the valve And very little air was released so I don't buy the claim that 1-2 PSI escapes due to the removal of the nozzle but the performance of the compressor way out weighs this little issue.

You can set the Desired presser on the gage and the compressor will stop putting air in the tire, but the compressor will not turn off. Would be nice if it did but maybe there is a reason.

I hope this review really helps those who were in the same shoes as me with wanting a fairly inexpensive mobile air compressor that is compact and just does its job. If I have issues with it, I will update this review!

I don't care where this thing was made. It works. I had a spare tire that had to be inflated and this thing easily went from 0psi to 40psi in a very short time. Have used it repeatedly to level up tires on all cars. The accessories it comes with are phenomenal. Everything you need. I keep this full time in my truck for whatever comes up with tires. I have had it for 2 years now and no issues. If it went dead today I would buy another one.

This has worked well for the 6-8 times I have used it in three years to inflate vehicle tires.

This compressor will not seat tubeless bike tires for road, gravel or MTB bikes. It does not store up an initial charge of air, so it is not powerful enough for this use case. It's the same as trying to use a standard track pump for the job.

Unfortunately, mine did not come with the 90 degree press-on presta bike adapter like depicted in the product photos. I also had to request a replacement carry bag since the plastic zippers broke within two months.
