SMUGDESK

SMUGDESK USB-C to USB-C 3.2 Gen 2x2 20Gbps 100W 4K 60Hz 3m 2 Pack

SKU CH-YMNV-HMS7V

Two 3-metre USB-C cables deliver 20 Gbps data transfer, 100 W charging and 4K 60 Hz video output

  • 100W power delivery charges laptops fast
  • 20 Gbps data speed moves large files quickly
  • 4K 60Hz video output connects external displays
  • 3 metre length gives flexible desk placement
  • Two cables included for multiple device setups

Two-metre USB-C cable pair for 20 Gbps workflows

This two-pack supplies two three-metre USB-C to USB-C cables rated for USB 3.2 Gen 2x2 at 20 Gbps. Each cable handles 100 W power delivery and carries 4K 60 Hz video with HDR 10-bit colour and audio. The pair suits professionals who need long, high-speed links between laptops, docks, monitors and fast external SSDs without daisy-chaining shorter leads.

Sustained 20 Gbps throughput on long runs

The Gen 2x2 specification maintains 20 Gbps across the full three-metre length, so large project files move at consistent speed rather than throttling after a brief burst. Backward compatibility with USB 3.1, 3.0 and 2.0 ensures older peripherals still function, albeit at their native rates. The 100 W PD 3.0 profile keeps power-hungry laptops charged during extended transfers or multi-monitor sessions.

Plug-in simplicity with DP Alt Mode caveat

Both ends use standard USB-C connectors, so installation is a direct plug into host and device ports. The only common issue arises when a laptop or monitor lacks DisplayPort Alt Mode; without it the 4K 60 Hz video path will not activate even though data and charging work normally. Users should verify Alt Mode support on both sides before relying on the video feature.

Questions about this item

Does the 3-meter cable run hot or draw noticeable power when charging a laptop at 100W all day?

The cable is rated for 100W at 20V/5A and uses USB 3.2 Gen 2x2 conductors; it carries that load without active cooling and stays within normal operating temperature for a passive cable.

What must my laptop and monitor each support for the 4K 60Hz video and 20Gbps data to work through this cable?

Both devices need a USB-C port with DisplayPort Alt Mode; the host must also support USB 3.2 Gen 2x2 for the 20Gbps transfer rate.

Will this cable still deliver 100W charging and 4K 60Hz video if I connect it to an older USB 3.1 or USB 2.0 Type-C port?

Yes — the cable is backward compatible with USB 3.1, 3.0 and 2.0, so charging at 100W and 4K 60Hz video still work; only the data speed drops to the port’s maximum.
