PLS Note:
1. The Output Voltage, Current, or Watt is Determined by Your USB C Charging Block (for example: if your USB C Charging Block output max is 20V 3.25A 65W, then when working with this cable kit, the output max is 20V 3.25A 65W as well).
2. It is also important to be aware that anything that interrupts power will reset the output to 5V, such as a brief outage. When this happens, you cannot reset the voltage without unplugging both ends. You have to remove the power source to reset the voltage, and there has to be no load, or you cannot adjust the output voltage.
