Automatic shutdown: Plug the portable compressor power into the 12V cigarette lighter, connect the inflation hole to the tire air hole, indicate the pressure reading, and then set the desired pressure using the touch screen. Press the car air pump switch to start pumping. Once the inflator reaches the required pressure, the car compressor will automatically turn off. Pay attention to the OneAmg brand and the AMORGO store when purchasing. Powerful air pump and fast inflation: Our portable air compressors have a maximum air pressure of 150 PSI and can lift car tires from 0 to 35 PSI in 4 minutes. This makes emergency tires easier and more convenient. We use durable ABS plastic and stainless steel in the portable air compressor pumps. This allows you to use the digital tire inflator / tire for a long time. Touch screen and emergency lighting at LED: It uses a high-precision and bright touch screen, which allows you to set the default tire pressure more clearly and accurately. The inflator compressor can be preset to four unit values (PSI, BAR, KPA, KG / CM). Digital Air Compressor is equipped with an LED lamp that allows you to easily handle emergencies and quickly make repairs on dark and deserted country roads. Multiple use: The auto compressor is equipped with 3 meters cable to inflate the wheels of a motorcycle, bicycle or mid-size sedan SUV, etc. In addition, three nozzle attachments allow you to inflate sports and camping equipment, such as kayak, airboat, air mattress, etc. The compact size and light weight make it easy to lift.
