Key Points
This 4-foot Thunderbolt/USB4 cable supports up to 40Gbps data transfer, which shortens large file transfers and reduces waiting time when moving media or backups. It can drive a single 8K@60Hz display or dual 4K@60Hz monitors, and supports MST daisy chaining for multi-monitor setups. The cable includes an E-Marker chip for negotiated power delivery and safety during high-watt charging. According to the manufacturer, it is USB-IF certified and is backward compatible with Thunderbolt 3 and USB 3.2 standards. Consider that peak performance depends on host and peripheral support for USB4 or Thunderbolt protocols.
