How to use

Plug one end of the Thunderbolt cable into the Thunderbolt port of the host device (laptop or dock) and the other end into the peripheral, display or storage device equipped with a compatible Thunderbolt port. Ensure both connected devices support the required Thunderbolt specification and power profiles to achieve full data and power performance. Route the cable to avoid sharp bends and maintain a gentle curve to preserve signal quality and cable longevity.

Usage recommendations

For optimal results, use this cable with devices that support the same or higher Thunderbolt generation and appropriate power delivery profiles. Avoid using passive adapters that may limit bandwidth or power. Keep the cable clear of sources of strong electromagnetic interference and do not exceed the specified bend radius to ensure reliable high-speed performance.
