Note: Ensure the device's rated input voltage matches the selected voltage level; never use a higher voltage with a lower-voltage device. Use a PD charger or power bank with a power rating at least 20% higher than the device's requirement. Confirm the DC plug size matches the device port. Connect the Type-C end to the PD power source first, then switch to the correct voltage, and finally connect the device. The PD charger or power bank must support the PD fast charging protocol.
