Review on 🚗 Efficient and Portable GSPSCN 12V Air Compressor Pump: Digital Display Tire Inflator with LED Flashlight, Dual Cylinder Design, 150 PSI Pressure, Auto Locking Air Chuck - Ideal for Auto, SUV, Off-Road, Truck, RV, Bike by Ethan Delaney

Pressure gauge was far away, it shows different pressures when unscrewing and when using an air chuck. When I adjusted the pressure to 32psi, the compressor started and then immediately shut off (the tire pressure was at 18psi). The pressure jumped to 42psi even though the tire pressure was 18psi. If I increase the reading to 50psi it works as expected but then the shut down feature is disabled. Also when tightening the pressure dropped 3 psi, but with the chuck the pressure dropped 10 psi. I checked the psi with 3 different gauges with the same result. product return.
