Product Identity

This Thunderbolt 4 cable delivers 40Gbps bandwidth with 240W power delivery and 8K60Hz video support. It targets professionals moving large media libraries and users charging high-power laptops like the 15-inch MacBook Pro. The integrated E-marker chip ensures stable performance across all supported modes.

Capacity and Headroom

The cable handles single 8K60Hz displays or dual 4K60Hz outputs when the host supports DisplayPort Alternate Mode. Data moves at 40Gbps, transferring 10GB in roughly 5 seconds. Power reaches 240W (48W at 5V), charging a 15-inch MacBook Pro in 60 minutes. Backward compatibility covers USB 3.2, 3.1 and 2.0 devices at their native speeds.

Bundled Value

The alloy connector heads provide corrosion resistance for long-term reliability. No additional adapters or software are included in the package. The cable itself is the complete product, ready for immediate use with Thunderbolt 3, Thunderbolt 4, USB4 and compatible USB-C hosts such as Steam Deck or Nintendo Switch.

Questions about this item

Will this cable work with my older USB 3.1 dock and still carry video?

The cable is backward compatible with USB 3.1 and USB 3.2, but video output requires the host device to support DisplayPort Alternate Mode.

How can I verify the 40 Gbps link is active after I plug it in?

Check the operating system connection speed or run a large file transfer; a sustained rate near 40 Gbps confirms the link is operating at full Thunderbolt 4 performance.

Does the 4 ft cable include a power adapter or only the cable itself?

Only the USB-C to USB-C cable is included; a compatible USB-C charger must be purchased separately to deliver up to 240 W.
