One cable for every USB-C need

This 3.3 ft Thunderbolt 4 cable works with Thunderbolt 3, Thunderbolt 4, USB4 and all earlier USB-C standards. It replaces separate charging, video and data cables for laptops, docks and high-speed storage. Buyers who need a longer run or an angled connector will need a different product.

Fits any USB-C port without extra adapters

The cable carries up to 100 W of power so a single connection can charge a gaming laptop while driving an 8K display at 60 Hz or dual 4K displays at 60 Hz. Data moves at up to 40 Gbps, cutting large-file transfers to seconds. Systems without DisplayPort Alt Mode on their USB-C port cannot use the video function.

No software or accessories included

The cable is a pure hardware link; there are no drivers, utilities or bundled adapters to install. Performance depends entirely on the host, charger and display capabilities. Users simply plug both ends and the connection negotiates the highest shared speed and power level automatically.
