FAQ
Most Type-C charging devices do not output voltage by default.
Type-C charging ports usually remain inactive until a load protocol is detected. Once a compatible load is connected and the charging protocol is negotiated, the output voltage will become active and the display will turn on.
This product displays real-time charging parameters, not the charger’s rated maximum values.
The values marked on the charger indicate its maximum supported current or power. During actual charging, the output depends on the connected device, charging protocol, and current charging stage, so the measured current or power may be lower than the rated specifications.
This is normal behavior caused by bidirectional current detection.
The product uses bidirectional current sensing, which may result in a small idle current reading even without a load.
This idle current can be calibrated and eliminated by the following steps:
1. Ensure no load is connected.
2. Press and hold the button.
3. While holding the button, connect the Type-C port to a 5V power source.
4. Release the button when “CAL” appears on the display.
