What the cable delivers

This SMUGDESK USB C 4.0 cable moves data at up to 40Gbps and carries up to 240W of USB PD 3.1 Extended Power Range power. It is built for users who connect high-speed NVMe enclosures, eGPU docks or Thunderbolt 3 and 4 hubs to a laptop or desktop and need the full bandwidth those devices demand.

Build and everyday fit

The cable is 3.3 ft long and terminated with USB-C plugs on both ends. An integrated E-Marker chip negotiates the highest available power and data rates automatically, so the link stays stable when driving an 8K 60Hz display or dual 4K 60Hz monitors from a single port.

In the box and what it enables

Only the cable itself is supplied; no adapters or software are included. Plug it into any USB-C port and the hardware handshake handles 48V 240W charging, 40Gbps transfers and multi-stream video without driver installs, letting an SSD enclosure, dock or monitor work at its rated speed immediately.
