5.4 USB-C Power Delivery (PD) Charging
The USB-C power delivery port allows you to charge your host device while using the hub. This port is for power input only and does not support data transfer.
- Connect your original USB-C power adapter to the USB-C PD port on the hub.

6. Maintenance
- Keep the hub clean by wiping it with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Store the hub in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid bending or twisting the integrated USB-C cable excessively to prevent damage.
- Do not attempt to disassemble or repair the device yourself. Refer to qualified service personnel.
7. Troubleshooting
- No display output via HDMI:
- Ensure your host device's USB-C port supports video output (DisplayPort Alternate Mode).
- Check if the HDMI cable is securely connected to both the hub and the display.
- Verify that your display is set to the correct HDMI input source.
- Try a different HDMI cable or display to rule out compatibility issues.
- USB devices not recognized or working intermittently:
- Ensure the hub is securely connected to your host device.
- Try connecting the USB device directly to your host device to confirm it's working.
- If connecting a high-power device (e.g., external hard drive), ensure sufficient power is supplied to the hub, especially if your laptop is also charging through the hub.
- Disconnect and reconnect the hub.
- SD/TF cards not detected:
- Ensure the card is fully and correctly inserted into the slot.
- Check if the card is damaged or corrupted by trying it in another device.
- Ensure your operating system's file explorer is open and refreshing.
- Hub feels warm during use:
- It is normal for the aluminum casing to become warm during operation, especially when multiple ports are in use or when charging. The aluminum design aids in heat dissipation.
