Review on 🔵 Akface Portable Air Compressor Tire Inflator, 12V DC Digital Air Pump for Car Tires, Bicycles, and Inflatables with Auto Shut Off Feature - Blue by Eric Mueller

A great replacement for trips to the filling machine at the gas station. I've used it several times to adjust tire pressures due to mileage and ambient temperature variations. It seems accurate, outputting at most a few psi in a few minutes. You set the pressure you want, turn on the pump, and watch the pressure rise until the device turns off automatically. Mine always adds an extra 0.5psi, which I believe is a feature to allow for leakage when you remove the nozzle from the tire bar. And that's necessary, too, because the bicycle pump pressure nozzle is a bit difficult to remove and always releases some air. The device itself is surprisingly small and light - about the size of a 600-page hardback book, but lighter. Comes with cloth pouch and instructions. It uses the car's "cigarette lighter" socket for power. The power cord is long enough to reach all of my tires. When using it to inflate a pool or air mattress, you must be near a power source with such an outlet. The built-in light can be very useful in the dark. And - DON'T FORGET TO CHECK THE SPARE TIRE. My blood pressure has dropped a lot. Unlike others, this pump pumps over 60psi, which is required for today's replacement parts.
