Why does the Mijia Compact Portable Electric Air Compressor show a pressure reading of zero?
If the Mijia Compact Portable Electric Air Compressor shows a pressure reading of zero, please refer to the following methods:
1. Confirm the type of item you are inflating and check its pressure range. The Mijia Compact Portable Electric Air Compressor is designed for inflating high-pressure items such as tires; low-pressure soft items like balloons, swim rings, or inflatable toys fall outside the device’s measurable pressure range, which will directly cause the screen to show a zero pressure reading. Please use the air compressor only for items matching its pressure measurement specifications.
2. Check and re-secure the connection between the valve connector and the inflatable item’s valve. A loose, improper, or incomplete connection between the valve connector and the tire/ item valve will prevent the device from accurately detecting the real-time pressure inside the inflatable item, thus leading to a zero-pressure reading on the display. Tighten the valve connector firmly and ensure it forms a tight, sealed fit with the valve to restore normal pressure detection.
