4.1 Reading the Display

  • Power Display (W): The main numerical value indicates the current charging power in Watts (W). This value updates in real-time.
  • PD Icon: A "PD" icon will appear next to the power reading if the device detects a Power Delivery (PD) fast charging protocol.
  • Fast Charging Indication: The presence of the "PD" icon signifies that fast charging is active. If the PD icon is not displayed, it indicates standard charging or a non-PD fast charging protocol that the tester might not specifically label as "PD".
