I needed it urgently and because I had bought the equivalent in another brand for someone else (usually they are Chinese fason that just change brand and colors), I chose this one. It seems to be quite powerful for a 12V air compressor. It has a screw-on adapter on the valve integrated into the hose and additional attachments for other uses (air mattresses, balls, etc.). It seems to have a small leak in the connection of the integrated hose with the pressure gauge, but only when the compressor is not in operation. I repaired a car tire that had a nail in it. It inflated it from 0 to 2.5 bar in about 5 minutes. If the car engine is running during use, it has a more stable performance and does not struggle with high pressures. If you inflate a flat tire, give the pressure gauge some time to show accurate readings.
