2. Setup
To set up your YiKaiEn Multi-Voltage Adapter Cable, ensure you have a compatible USB-C Power Delivery (PD) adapter or power bank. The cable itself does not generate power; it converts the PD output to the required DC voltage.
- Connect the USB-C end of the adapter cable to a compatible PD power source (e.g., a PD wall adapter or PD power bank).
- Select the appropriate DC connector tip from the included 11 tips that matches your device's power input port.
- Attach the selected DC connector tip to the DC output jack of the adapter cable.

3. Operating Instructions
Once the cable is connected to a PD power source and the correct DC tip is attached to your device, you can adjust the output voltage.
- Power On: Ensure the USB-C end is securely connected to a PD power source. The LED display on the adapter cable will illuminate.
- Select Voltage: Press the button on the adapter cable to cycle through the available voltage outputs: 5V, 9V, 12V, 15V, and 20V. The LED display will show the currently selected voltage.
- Connect to Device: Insert the DC connector tip into your device's power input port. Ensure the selected voltage matches your device's requirements to prevent damage.

Important Usage Tips:
- If using a standard USB 3.0 charging adapter (not Type-C PD), the voltage will be fixed at 5V. To utilize the 5V/9V/12V/15V/20V switching functionality, a Type-C Power Delivery (PD) charging adapter is required.
- Always verify that your device's voltage and wattage requirements are met by the selected output and the connected PD power source.

4. Maintenance
To ensure the longevity and reliable performance of your YiKaiEn adapter cable, follow these maintenance guidelines:
- Keep the cable and connectors clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Avoid extreme temperatures and humidity, which can damage electronic components.
- Do not bend the cable sharply or apply excessive force to the connectors, as this can cause internal damage.
- Store the cable neatly coiled when not in use to prevent tangling and stress on the wires.
5. Troubleshooting
If you encounter issues with your YiKaiEn adapter cable, consider the following troubleshooting steps:
- No Power Output:
- Ensure the USB-C end is firmly connected to a functioning PD power source.
- Verify that the PD power source itself is powered on and providing output.
- Check if the LED display on the adapter cable is illuminated and showing a voltage.
- Incorrect Voltage Output:
- Press the button on the adapter cable to cycle through voltages until the correct one for your device is displayed.
- Confirm that your power source is a USB-C Power Delivery (PD) adapter. Standard USB 3.0 ports will only output 5V.
- Device Not Charging/Working:
- Ensure the selected DC connector tip is the correct size and type for your device.
- Double-check that the voltage displayed on the adapter matches your device's required input voltage.
- Confirm that your device's wattage requirement does not exceed the adapter's maximum output (Max 20V 3A / 65W).
- Test with another compatible device or power source if possible to isolate the issue.
