Note: Ensure the device's rated input voltage matches the selected voltage; never supply higher voltage to lower voltage devices. Use a PD charger/power bank with rated power at least 20% above the device's requirement. Confirm the DC connector size matches your device. Connect the Type-C end to the PD power source first, then switch to the appropriate voltage, and finally connect the device. The paired charger/power bank must support PD fast charging protocol.
