Operating Instructions

Charging Your Device:

  • Connect the cable between your USB-C power adapter (wall charger, car charger, power bank) and your USB-C enabled device.
  • For optimal fast charging, ensure your power adapter supports Power Delivery (PD) and has a wattage output compatible with your device's charging requirements. This cable supports up to 240W.
  • The E-marker chip in the cable will automatically negotiate the appropriate power level for safe and efficient charging.

Data Transfer:

  • Connect one end of the cable to your computer's USB-C port and the other end to your device (e.g., smartphone, external hard drive).
  • Your computer should recognize the connected device, allowing you to transfer files at speeds up to 480 Mbps.

Video Output (Limited):

  • While this cable supports basic video output and monitor extension, its data transfer rate of 480 Mbps is suitable for standard display mirroring rather than high-resolution video streaming or advanced display functionalities. Ensure your device and display support video output over USB-C.

Maintenance

Proper care will extend the life of your UGREEN USB C cable:

  • Avoid Extreme Bends: While durable, avoid sharp or extreme bends, especially near the connectors, to prevent internal wire damage.
  • Keep Clean: Regularly wipe the cable and connectors with a dry, soft cloth to remove dust and debris. Avoid using liquids or harsh chemicals.
  • Store Properly: When not in use, coil the cable loosely and secure it with the included velcro strap or a cable tie. Avoid tangling or knotting.
  • Handle with Care: Always pull from the connector head, not the cable itself, when unplugging from devices or power sources.

Troubleshooting

Problem Possible Cause Solution
Device not charging. Loose connection, incompatible power source, faulty device port. Ensure both ends of the cable are securely connected. Try a different power adapter or wall outlet. Test with another device to rule out a faulty port on your device.
Slow charging speed. Power adapter does not support fast charging, device limitation, background apps. Use a Power Delivery (PD) compatible charger with sufficient wattage (e.g., 60W, 100W, 140W, 240W). Close unnecessary background applications on your device.
No data transfer. Loose connection, incorrect device settings, driver issues. Check cable connections. Ensure your device is set to 'File Transfer' mode (if applicable). Try connecting to a different USB-C port on your computer. Update computer drivers if necessary.
Cable appears damaged. Physical stress, improper handling. Discontinue use immediately to prevent potential damage to devices. Contact UGREEN support for warranty information.
