LYSNSH Portable Air Compressor Pump - DC 12V Small Digital Car Tire Inflator with Gauge 120 PSI

I needed a small compressor to keep in the car because my Viair compressor always got hot and was loud and the Kobalt (12v/AC/DC) compressor was taking up too much space and wouldn't fit into the toolbox. I was somewhat skeptical but found a need for it when a coworker had a flat tire and a flat spare tire as well.So I plugged it in and expected it to be loud - it wasn't. Punched in 55 psi (flats take 50-60 psi) and this unit kept on going with no vibration, very quiet,and the best part it wasn't burning my fingers when I touched it, the plastic cover does a good job.I was impressed by the fact that it came with a case and has a small form factor, I bought another one for my dad's car as well, I'm impressed thus far and typically put in 38 psi into the Lexus truck

I love this thing. I have a tire that has a small leak and every other week I have to fill it back up with air. This thing has been a life saver. It works exactly what you'd expect, it inflates at a fair rate, and it's built well enough that I have no concerns about keeping it in the back of my care. In my opinion this thing is perfect for what I use it for. Well done Mbrain

The pump is nice, small, quiet, can set a set point pressure where it will stop so ;you don't have to be starring at it to know when it is at pressure, it has a light in case you use it at night, it has a digital display, has a nice little bag to store it in, and a fell pro fastener for the power cord. It is really a nice and very practical pump. It pumps slower than another pump I have, but the other pump is way louder also and bigger.

I have now used this many times over the past months. The preset feature for auto-shut-off pressure is very nice. The gauge is easy to read and I prefer this design over the rectangular-plastic-box type. The pressure reading compares well to a couple pressure gauges I have. An improvement could be a more "aggressive" knurl on the brass valve connection or a rough-textured overmold. It can slip easily in cold, dry hands when I'm putting it on and taking it off. The longer it takes me, the more air escapes. To compensate, I usually set the pressure for 1 psi over what I really want. Wearing certain gloves also helps.

It's OK but not great. Too small to fill tires quickly/ If I have to add 5 pounds per tire it's too hot and needs a rest to cool off. If I set the pressure at 38 lbs and then check it with a digital gage, there will be a 3 lb difference. When I check the next tire with the same gage there might be a 5 lb difference. // My bad, I should have purchased a larger and more expensive compressor.

I always like to keep an air pump in the trunk of my car to top off my tires when winter rolls around or to handle a slow leak until I get it patched. Previously I had this Slime portable air compressor: https://www.amazon.com/Slime-40043-Inflator-Light-Trucks/dp/B01N1PQ9KN, but it broke when someone threw something in my trunk and crushed the power plug. So I decided to switch brands and give Mbrain a try. This compressor is wayyyyy quieter and I love how easy it is to read the digital pressure gauge and set a target pressure. If this one ever breaks, I'll definitely be buying another Mbrain compressor.

I bought it for a month and now I finally use it. Get out in the morning and start driving to work. The system detected low tire pressure. When I got out of the car, I found a small screw on the tire. There's no time to catch up with the repair shop. Thanks to this air pump, the biggest trouble was solved today. This pump is really good, it's quick and easy to use. The pump has a number on it, and I set it to 33 pressure. When inflation reaches 33, the filling pump will stop automatically. It works really well, thank you very much.

Tried running the compressor to pump up my car tire on a cold day and the compressor would not even run when connected to my air intake valve. It BARELY ran when disconnected, compressor sounded VERY weak and definitely was made of very cheap components. Would not recommend. Get a hand pump over this trash.
