Care and Maintenance
- Cleaning: Use a soft, dry cloth to clean the adapter. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Handle the adapter with care. Avoid dropping it or subjecting it to strong impacts.
- Heat Dissipation: The adapter's aluminum casing is designed to dissipate heat efficiently. It is normal for the device to feel warm during extended use, especially when multiple ports are active or when charging. Ensure adequate ventilation around the adapter.
Troubleshooting
| Issue | Possible Solution |
|---|---|
| No display on external monitor. | Ensure the HDMI cable is securely connected to both the adapter and the monitor. Verify the monitor input source is set correctly. Check if your host device supports external display output via USB-C. For macOS, ensure the resolution is set to 4K@60Hz or lower. |
| Host device is not charging via PD port. | Confirm your USB-C PD charger and cable are functional and capable of delivering sufficient wattage (up to 100W). Ensure the charger is connected to the adapter's USB-C PD port, not a data port. |
| USB devices or memory cards are not recognized. | Try reconnecting the device or card. Ensure the adapter is firmly connected to your host device. Test the device directly with your host device if possible to rule out a peripheral issue. Restart your host device. |
| Adapter feels warm during use. | This is normal. The aluminum casing is designed to dissipate heat generated during operation, especially under heavy load (e.g., 8K video output, multiple connected devices, or fast charging). Ensure adequate airflow around the adapter. |
| USB-C port on the adapter does not work for data transfer. | The USB-C port on this adapter is exclusively for Power Delivery (PD) and does not support data transfer. Please use the USB-A ports for data peripherals. |
| The connection to the laptop feels loose. | Ensure the USB-C connector from the adapter is fully inserted into your laptop's port. While the design is robust, a loose connection can sometimes occur if not fully seated. If the issue persists, try connecting to a different USB-C port on your laptop if available. |
