Skight 160PSI 7500mAh Air Compressor

First let me say that I have tested this Inflator/Pump for several weeks and this is genuinely a fantastic item with surprising build quality. If you want to skip the back story you can skip to the 2nd section however, this is important. I have tried many portable inflators or pumps. I do my research more than most people would care to. Today there is so many cheap or poor quality products but this is not one of them. Like I mentioned, I've tested many and for a short period I was on a mission to find a few good quality air pumps for each automotive emergencies couple at home for bicycles, scooters, and other things. Some pumps that I purchased had to be instantly returned for poor quality but kept a few or the better ones. This Skight lithium battery powered inflator was the last that I purchased and wish it had been the first. Don't get me wrong I found some really good ones made by Husky that come in both 12 volt version for automotive as well as 120 volt version for home. But nothing like this bad boy with no power cords and still have the power I'm looking for. First thing that is noticeable is the build quality. This inflator feels very solid from the hose tip connector all the way to it's buttons. The buttons feal solid. This thing feels like it can take a beating without worry. Having a screw-on hose connector instead of the push-on lever type is the most solid and long lasting connection you can get. The manufacture did not cut any corners that I can see. Seeing this type of connector gets my attention as they last forever, don't leak, allow unrestricted air flow, and so easy that a child can use it. There is no fighting with a tight lever on a valve stem. Do not let the size of this fool you either. This pump is apparently made to be minimal in size but other inflators are made to "appear" bigger in size with large simulated housing the shape of a cylinder head or motor to make you think your getting a big pump for the money. This pump is minimal in size but packs a big punch. Watch the video, it only takes seconds to top off a bicycle tire. I was surprised at how well the motor sounds and the power. Most inflators sound loud, rattling like they are going to fall apart but this one sounds quiet, smooth, yet powerful. It has 3 large Lithium 2500mah batteries which help explain its high power to weight ratio weighing approximately 21oz. There are 4 Presets with 1 User to customize. Presets include car, atv, bicycle, basketball. The pump will auto-stop at the predetermined preset however, at any time you can override the end pressure by simply pressing the + or - key. The inflator with raise the pressure to your prefer setting then shut off. You can choose between PSI, Bar, KPA, or Kg/cm. You can use the User function to customize your own air pressure or simply override the other presets if you choose. I find the pregrammed presets good for kids or less experienced person for pumping bicycle tires or balls. All they have to do is choose is the Logo accordingly and it shuts off on its own. These presets prevent them from over or under inflating. This device does a good job on automotive tires too. Can you imagine you or your wife having a leaking tire and use this to get you going fast with no cigar lighter extension wires to plug in? Even around the house we grab this inflator over the others so we don't have find a outlet to plug in or re-wrap long cords for storage. I could keep listing all the good things but I don't want to forget one important feature that it has which is a USB outlet to charge devices. This doubles as a extra large power bank. My advice for longevity. I have a lot of experience in devices like this as well as lithium technology. Even though this inflator can handle some abuse, the idea is to make sure it last as many years as possible. I recommend allowing it to rest and cool down briefly in between sessions when it's non emergency. This goes for any device like this. Both the electric motor and the Lithium battery would appreciate a short rest in between pumping two, three, or more items. Also try not to repeatedly deplete the battery down to zero and give partial recharges. When your able to, when it gets down to around 40%, recharge it completely too 100% and you will always be able to depend on it to work. I plan to buy one more.
