Usage Notes Before use, confirm that your laptop has a 7.4 × 5.0mm charging port and check the wattage of its original power adapter. Select the mode that matches the device's original power-adapter wattage to help prevent adapter-recognition errors, insufficient-power warnings, or other error messages. Lightly press and quickly release the button when switching modes. Holding it down may cause the settings to cycle continuously. The red setting is intended only for devices rated at 150W or below and is not suitable for high-power applications. If the LED flashes, check whether the selected mode matches the device's power requirements and confirm that the connection is secure. If the button does not respond, disconnect the power for 10 seconds and then reconnect it. Directly skipping a setting is not supported. The five modes must be selected sequentially. 5.
