Cable length and standard
The SMUGDESK cable measures 1.64 ft and meets the USB4 and Thunderbolt 4 specifications. It suits users who need a short, high-bandwidth link between a host and a dock, drive or display. The plug works with Thunderbolt 3 and 4 ports as well as USB 3.2, 3.1 and 2.0 devices. Buyers who need a longer reach for desk routing should look elsewhere.
Data rate and charging
The link moves data at 40 Gbps and can deliver up to 240 W of power, replacing earlier 60 W and 100 W cables. In normal use the thin 1.64 ft run stays cool and adds no audible noise. No external power supply is required for the cable itself.
Display upgrade and limits
One 8K or 5K monitor at 60 Hz or two 4K monitors at 60 Hz can be driven when the host port supports DisplayPort Alt Mode. The step up from older Thunderbolt 3 cables is worthwhile only if the system and display both handle the higher bandwidth and power. If the host lacks Alt Mode, video will not work.

Questions about this item
How do I install the 1.64FT USB 4 Thunderbolt 4 Cable and what step do people often get wrong?
Connect the USB-C ends to Thunderbolt 4 or USB4 ports on both devices. The common mistake is plugging into a USB-C port that lacks DisplayPort Alternate Mode, which is required for 8K@60Hz video output.
What maintenance or replacement will this cable need over time?
The cable itself has no serviceable parts. Inspect the USB-C connectors periodically for debris or bent pins. Replace the cable if the braided jacket frays or if 40Gbps data or 240W charging performance drops.
What limit appears first during sustained heavy use of this cable?
The 240W power delivery ceiling is the first hard limit. Continuous 240W charging can heat the connectors, so the cable may throttle power before the 40Gbps data bandwidth saturates.
