How can one love a portable air compressor pump?? Well, with this little baby from Helteko, it's possible. Received my new ordered Helteko Digital Air Compressor (ATJ-1166S) from Amazon approx. 4 or 5 days after I placed my order. Immediately got an opportunity to use the air pump on all 4 of my car tires topping up the pressure from 32.5 to 35psi. The pump worked flawlessly which made me a very happy camper. Here is my impression after my first use:Pro #1 - The pump comes with an easy-fastening chuck (piece on the end of the air hose that attaches to the tire valve) that has a lever that clamps down to tighten the connection between the air hose and the tire valve and can be removed at the end of inflation without much air escaping from the tire. The other common type of chuck that I've seen on other air compressor pumps is a screw-on which, to me in theory, is not easy to connect and disconnect without having much air leak from the valve.Pro #2 - This air compressor has an auto shutoff feature that turns the pump off when the pumps digital guage display has reached the desired air pressure that you presumably have chosen before pressing the on button. However, the pump does, by design, inflate an extra .5psi to 1.0psi in order to compensate for any air that might be lost while removing the air hose from the valve. But, as mentioned, because of the more efficient and easy-to-use chuck, the amount of air escaping upon removal is usually minimal. In this case, I just intentionally remove what ends up being a slight amount of air manually and refasten the air hose to get another psi reading that is perfect with the initially desired psi that was entered. TIP: make sure the air hose is free of all kinks and bends before fastening to the valve, as I've noticed at times that this might affect the accuracy of the gauge reading.Pro #3 - One of the reasons I bought the Helteko air compressor pump was because it does come with a nice nylon carrying case that I store in my SUV's cargo area. Very convenient and does not take up too much space.Pro #4 - After my first or second use I proceeded to pack the device into the supplied carrying case, began to zip it closed when the zipper head broke off and separated from the adjoining track. Needless to say I was very surprised and somewhat disappointed at the time. Another reason I purchased the Helteko pump was because I had read a good number of Amazon customer reviews that were very positive and impressed with the Helteko customer service when it came to standing behind their product. I immediately emailed the Helteko customer support team and Steven (customer care manager) responded to my request for a new case within 2 hours after having sent my email. Long story short, I received my replacement carrying case in the mail 10 days latter, given an understandable delay in delivery due to the end of year holidays. Nonetheless, I thought this was outstanding customer service - the way I believe ALL and ANY customer service should be regardless of the product or service !!Bottom Line: You can not go wrong buying this portable air compressor pump. Like me, I believe you will love it !!

This meets all expectations!Not sure why so many people are saying this is inaccurate. I say 36, it goes 36. I say 38, it goes 38. I have seen a ton of videos of these and read the comments and so many people are saying it is .5 or a whole pound off. Mine is exactly what I set it to.To be fair, I only used it once so far so I will need to update this if I go to turn it on a second time and it does not work. It was a bit tough to get going or it dies after 10 or so uses. I set the PSI, pressed the power button, and walked away. It just sat there. I kept pressing buttons and before I knew it, it started to pump. It went right to my desired number which was about 6 psi in around 1 minute. Slightly faster than my previous pump so that was a plus.This is very small and comes with it's own bag which is much more than can be said about other compressors of this same make with different branding. As many have mentioned, the cord length is extremely long. Easily can reach across the average sized driveway. The pump hose itself is long enough to reach the tallest valve stem, but not long enough to have the compressor sit inside the car while running. The hose tucks right back into the compressor itself and cord can snugly fit aside the device in the provided bag. Another thing I love about this is the plastic clip lock. My old unit had a 100% metal one and over the years it needed some WD-40, because this is plastic, it will never rust or stick (just have to be careful not to snap it). Some have said that they had trouble with the rubber on the inside not fitting around the stem. I did not have this issue, but again had that issue with my older unit so I think it is just how these things are manufactured. It is not silent, but is much quieter than my old pump as well. A lot of the videos you find online of this thing make it sound like a failing motor for a boat, but it is quiet enough to be faint once you get 10 feet away from it.Based on the unit I received, I highly recommend this pump. It does the job, does it fast, is so small it can fit in any tight spot of the car for storage, and is a great price in comparison to others!
