High-speed USB4 cable
The SMUGDESK USB 4.0 cable delivers 40Gbps data transfer and 100W power delivery over a 1.6ft length. It supports Thunderbolt 3 and 4 hosts while remaining backward compatible with USB 3.2, 3.1 and 2.0 devices.
Capacity and headroom
The cable drives a single 8K display at 60Hz or dual 4K displays at 60Hz when the host port supports DisplayPort Alternate Mode. Data throughput reaches 40Gbps, doubling the rate of earlier Thunderbolt 3 links, while 100W charging powers demanding laptops during use.
Build integration
A nylon-braided jacket protects the 1.6ft run between a host and a dock, monitor or high-speed SSD. Thunderbolt 3 and 4 compatibility lets one cable serve current MacBook Pro models, recent Windows ultraportables and existing Thunderbolt 3 peripherals without adapters.

Questions about this item
Will this 40Gbps Thunderbolt 4 cable work with my older USB-C 3.2 and 3.1 devices?
Yes, the cable is backward compatible with USB-C 3.2, 3.1 and 2.0 devices, so it will function with older ports at their native speeds.
How can I verify the cable is delivering 100W charging and 40Gbps data after I plug it in?
Check your laptop or dock's power meter for 20V at 5A and run a Thunderbolt-certified speed test to confirm 40Gbps throughput.
Does the 1.6ft braided cable include any adapters or do I need a separate DisplayPort Alt Mode monitor for 8K video?
The box contains only the USB4 cable; you must provide a monitor or dock with a USB-C port that supports DisplayPort Alternate Mode for 8K@60Hz output.
