Overview

The Belkin Thunderbolt 4 Cable is a USB-C to USB-C cable designed for the latest Thunderbolt 4 standard. At 1 meter in length, it delivers up to 40Gbps data transfer, 100W Power Delivery fast charging, and 8K video output in a single cable. It is also USB4 compliant and backward compatible with Thunderbolt 3, USB 3.2 Gen 2, and earlier standards. This cable is ideal for laptop users who want to consolidate charging, data, and display connections through one cable, especially when paired with a Thunderbolt 4 dock. The braided nylon jacket adds durability for everyday use and travel, while the sleek black finish keeps your desk tidy.

Connectivity & Compatibility

The cable features USB-C connectors on both ends. It works with Thunderbolt 4, USB4, Thunderbolt 3, USB 3.2 Gen 2x2/Gen 2/Gen 1, and USB 2.0 devices. However, actual speed and power delivery depend on the weakest link in the chain. For example, connecting to a USB 3.2 Gen 2 port limits data to 10Gbps, and 100W PD charging requires a compatible charger and device. Video output supports DisplayPort Alt Mode, enabling 8K@60Hz or dual 4K@60Hz on a Thunderbolt 4 port. It is compatible with a wide range of devices: MacBook Pro, MacBook Air, iPad Pro, Windows laptops, and even some Android phones with USB-C. For best results, use with a Thunderbolt 4 port on both ends.
