Review on 🚗 Portable Air Pump for Car Tires - 150 PSI DC/AC Tire Inflator with Pressure Gauge, LED Light, Auto Shut Off - Suitable for Car, Bike, Motorcycle, Ball, Inflatable Pool by John Miranda

I bought this little compressor for a specific application. My scooter has wheels with metal valve stems and it's difficult to access the valve to inflate or check the pressure with a regular air chuck (I have several, none of them worked too well). I also wanted one that runs on 110 and this one ticks that box too. It also runs on 12V DC with the included adapter. My bike is equipped with TPMS so I was curious to see how exactly this device adjusts the pressure. You can set the pressure you want in psi or bar, I set the front to 36. The pressure went up to 36 and when it stopped the pressure was around 33. So I pushed the button again. It ran for a few seconds and stopped at 34. I repeated the process a few more times until it stopped at 37 and removed the latch on the chuck. Did the same with the rear wheel on 42. I then took the bike out and was pleasantly surprised to see 36/42 tires as listed. Color me happy about it. The unit seems pretty well made for what it is, about as noisy as other small compressors. It has a built-in light that can change from white to red. The hose is stored in a chute in the back, I haven't tried to see where the two power cords are stored, that's probably a thing they didn't design.
