Thunderbolt 4 cable for high-speed workflows

This Thunderbolt 4 cable connects USB-C devices at 40 Gbps and carries up to 240 W of power. It supports a single 8K display at 60 Hz or dual 4K monitors, making it suitable for creative professionals moving large media libraries between laptops, docks and external drives.

Certified build with 5 000-bend endurance

Intel Thunderbolt certification confirms full 40 Gbps bandwidth and 240 W (48 V / 5 A) power delivery compliance. Laboratory testing rates the cable for 5 000 bend cycles, so repeated coiling and travel stress are accounted for. One cable in the box handles data, video and charging without extra adapters.

Suits users needing one cable for dock.

Buyers who want a single short cable to drive an 8K monitor, fast SSD and laptop charging simultaneously will benefit. Users requiring longer reach than 1.5 ft or legacy USB-A connectivity should look at something else.
