What this cable does
The SMUGDESK USB4 Thunderbolt 4 cable connects two USB-C devices with a male-to-male plug over a 1.64FT length. It supports up to 40Gbps bandwidth for data, video and power delivery. The cable works with Thunderbolt 4 and Thunderbolt 3 hosts, external SSDs, eGPU enclosures and USB-C docking stations. It is built for users who need a single short link that carries maximum throughput.
Thermals noise and power
Passive copper construction means no fan noise and no active cooling requirement. The cable handles up to 240W at 48V/5A when paired with a compatible charger, so it can power gaming laptops and other high-draw devices. Power delivery negotiates automatically with the host and peripheral. No external power adapter is needed for the cable itself.
What the bundle changes
The package contains only the 1.64FT cable; no adapters, docks or software utilities are included. Compatibility with 8K 60Hz or dual 4K 60Hz displays depends on the host controller and monitor capabilities. Data rates reach 40Gbps on Gen3 ports and fall back to 20Gbps on Gen2 ports. Buyers who need a longer reach or additional connectors must source those separately.

Questions about this item
How do I connect the male-to-male USB-C ends to my laptop and eGPU dock?
Plug one USB-C connector into the host port and the other into the eGPU dock; ensure both ports support Thunderbolt 4 or USB4 40Gbps to unlock full bandwidth.
Will the 240W charging capability degrade over time with daily use?
The cable is rated for 48V/5A 240W power delivery; sustained high-wattage charging may warm the connectors, but no user-replaceable parts or scheduled maintenance are specified.
At what point does the 40Gbps data rate drop during a long file transfer to an external SSD?
Bandwidth stays at 40Gbps only on USB4 Gen3 or Thunderbolt 4 ports; on USB 3.2 Gen2 ports it falls to 20Gbps, which becomes the first limit under sustained loads.
