- Option 1: Full-Functioned Type-C x2
Ensure your laptop has two full-functioned Type-C ports that can provide video signal. Use the provided USB-C to USB-C cables. - Option 2: Full-Functioned Type-C & HDMI
If your laptop has one HDMI port and one full-functioned Type-C port, use the HDMI to USB-C cable and one USB-C to USB-C cable. - Option 3: HDMI & USB-A
For laptops with a USB-A port (or a standard USB-C port for power only) and an HDMI port, use the included H5 adapter along with an HDMI cable for video transmission and a USB-C to USB-A cable for power.
Important Note: If you encounter a "No Signal" error, it means your USB-C port is for power only. In this case, use the included H5 adapter cable to transmit video. This is a common solution for MacBooks and some ultrabooks.

3. Maintenance
3.1 General Care
To ensure the longevity of your screen extender, keep it clean and handle it with care. Use a soft, dry cloth for cleaning. Avoid harsh chemicals or abrasive materials. Store the unit in its carry bag when not in use to protect it from dust and scratches.
3.2 Power Bank Care
To maximize the lifespan of the 10,000mAh power bank, avoid fully discharging it regularly. Recharge it when the charge level is low. Store in a cool, dry place away from extreme temperatures.
4. Troubleshooting
4.1 No Signal Error
If you encounter a "No Signal" error, it typically indicates that your laptop's USB-C port is for power delivery only and does not transmit video. In this scenario, use the included H5 adapter cable to transmit the video signal from your laptop's HDMI or USB-A port.
4.2 Display Issues
If the display has no signal or the signal is unstable after connection, please connect an external 5V/2A power adapter to power the laptop. Ensure all cables are securely connected.
4.3 Audio Quality
While the KEFEYA S5 includes built-in speakers, for optimal audio experience, it is recommended to use your laptop's speakers or external audio devices.
