Cable Length 3.3 Feet

  • Charges devices up to 240W with 48V 5A power delivery
  • Transfers data at 40Gbps for rapid file movement
  • Drives a single display at 8K 60Hz resolution
  • Works with Thunderbolt 4 and earlier USB-C gear

Cable purpose and audience

The SMUGDESK USB4 cable connects two USB-C devices for video, data and power. It suits laptop owners, docking-station users and anyone driving an 8K or dual-4K display from a single port. Buyers who need longer reach or legacy USB-A connectors cannot use this cable.

Deciding specification

The cable delivers up to 240 W (48 V/5 A) power delivery, 40 Gbps data throughput and 8K/6K at 60 Hz video over a 3.3 ft length. It is backwards compatible with Thunderbolt 3, USB 3.2, 3.1 and 3.0. The connected charger, host and display must each support the target rate to achieve these figures.

Installation and common issues

Plug the male USB-C ends into the host and the peripheral; no drivers are required. Ensure both ports and the power source are rated for the desired wattage and bandwidth, otherwise charging or video will fall back to lower speeds. The fixed 3.3 ft length may be too short for some desk layouts.

Questions about this item

What does 40Gbps mean when the cable is connected to a laptop and SSD?

The cable supports up to 40Gbps theoretical throughput; real-world reads reach 2.8GB/s and writes 2.1GB/s when both host and drive support that speed.

Which Thunderbolt standard does the USB4 cable implement and what bandwidth ceiling does that set?

It is compatible with Thunderbolt 4, capping the link at 40Gbps for data and 8K/6K at 60Hz for video.

What physical clearance and connector orientation are needed to plug this 3.3FT cable into a dock?

The cable has male USB-C connectors on both ends and is 3.3FT long, so allow that reach plus the connector depth at each port.
