SMUGDESK

SMUGDESK PD100W USB cable 20Gbps 100W 4K 60Hz 10ft 2 pack

SKU CH-DTNZ-TDCQ0 MPN PD100W

Two 10 ft USB-C cables deliver 20 Gbps data, 100 W charging and 4K 60 Hz video in one pack

Model PD100W + 4K @60Hz

  • Transfers large files fast with 20Gbps USB 3.2 Gen 2x2 speed
  • Powers demanding laptops up to 100W through built-in E-Marker chip
  • Delivers crisp 4K 60Hz video to compatible monitors via DP Alt Mode
  • Two ten-foot cables give flexible placement for desk or travel setups
  • Works with Thunderbolt 3 and 4 devices for broad compatibility

Two-pack USB-C cable for power and video

Each pack contains two ten-foot USB-C to USB-C cables rated for USB 3.2 Gen 2x2 operation. They deliver up to 100W of power and carry 4K video at 60Hz when the host supports DisplayPort Alternate Mode. The cables suit laptop users who need a single cord for charging, data and an external display.

Built-in E-Marker chip manages power delivery

The integrated E-Marker negotiates USB Power Delivery from 5V up to 20V at 5A, covering 15W through 100W profiles. This automatic adjustment protects the connected device and keeps thermals low during sustained charging. No active cooling is required and the cable runs silently in normal use.

Requires DP Alt Mode for video

Video output works only on hosts with a USB-C port that supports DisplayPort Alternate Mode. Full 20Gbps data rates need a Thunderbolt 3 or 4 controller; lesser hosts will fall back to slower speeds. The ten-foot length frees desk placement but adds no signal amplification.

Questions about this item

How do I connect the SMUGDESK PD100W cable so the 4K 60Hz video signal actually works?

Plug each USB-C end into ports that explicitly support DisplayPort Alternate Mode; without DP Alt Mode on both the host and the display the cable will carry only power and data.

What part of this cable is most likely to wear out first and need replacement?

The built-in E-Marker chip and the USB-C connectors are the components that degrade with repeated insertion cycles and high-current 100W charging sessions.

At what point does sustained 20Gbps throughput hit a limit during a long transfer?

Thermal throttling in the host or target device typically caps real-world speed below the 20Gbps ceiling before the cable itself becomes the bottleneck.
