8. Maintenance

• Cleaning: Disconnect the charger from the power outlet and all devices before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or aerosols.
• Storage: Store the charger in a cool, dry place away from direct sunlight and extreme temperatures.
• Cable Care: Avoid bending or twisting charging cables excessively, as this can damage them over time.

9. Troubleshooting

Q: Why do my devices briefly stop charging when I plug in or unplug another device?

A: This is normal behavior. The charger intelligently re-negotiates power distribution to all connected devices when a change occurs, ensuring optimal and safe charging for each device.

Q: The charger feels warm during use. Is this normal?

A: Yes, it is normal for high-power GaN chargers to generate some heat during operation, especially when charging multiple devices or high-wattage devices like laptops. The UGREEN GaN II technology is designed for upgraded heat dissipation. If the charger becomes excessively hot to touch or emits smoke/unusual odors, disconnect it immediately and contact support.

Q: My device is not charging quickly.

A: Ensure you are using a high-quality cable that supports fast charging protocols (e.g., a 100W USB-C cable for laptop charging). Verify that your device supports the fast charging protocols offered by the charger (PD, QC, FCP, etc.). Also, check the power distribution guide to ensure the port you are using is providing sufficient wattage for your device, especially when multiple devices are connected.

Q: One of the charging ports has stopped working.

A: If a port ceases to function, first try using a different cable and device to rule out cable or device issues. If the port remains unresponsive, there may be an internal fault. Please contact UGREEN customer support for assistance.

10. User Tips

• Use Quality Cables: For optimal performance and safety, always use high-quality, robust charging cables that are rated for the power output you intend to use (e.g., 100W USB-C cables for laptops).
• Monitor Charging Speed: Be aware that charging speed typically decreases as your device's battery approaches 100% to protect battery health.
• Apple Watch Charging: It is generally not recommended to charge an Apple Watch simultaneously with multiple other high-power devices, as this may affect charging efficiency for the watch.
• Portability: The compact design makes this charger excellent for travel and business use.
