61W Wall Mount Adapter Apple USB-C PD Charger About the Power adapter: First of all, the nominal voltage of the general power supply refers to the open circuit output voltage, that is, the voltage when there is no load outside and no current output, so it can also be understood that this voltage is the upper limit of the power adapter output voltage. When the active voltage stabilizing element is used in the power supply, even if the mains voltage fluctuates, its output is also constant. If the mains voltage fluctuates, the output of the power supply will not fluctuate with it. Generally speaking, the real no-load voltage of the general power adapter is not necessarily the same as the nominal voltage, because the characteristics of the electronic components cannot be completely consistent, so there is a certain error, the smaller the error, the higher the consistency requirements of the electronic components. 61W Wall Mount power Adapter Apple USB-C…
