Before use, you can set the tire pressure in advance, connect the air nozzle and start it. The inflation process will display real-time changes in tire pressure. The device has basic protection design. After working for a period of time, it will trigger an overheating protection to reduce the wear and tear caused by prolonged idling. During daily self-driving or short trips, having one of these on the vehicle is convenient for monitoring and replenishing tire pressure at any time, reducing the risks caused by abnormal tire pressure.
