A six point six foot USB C to USB C cable with reversible connectors

SMUGDESK

SMUGDESK 100W Thunderbolt 4 USB4 Cable 40Gbps 8K 6.6FT

SKU CH-5E1D-T45K4

A USB-C cable delivering 100 W power, 40 Gbps data and 8K 60 Hz video over 6.6 ft

Cable Length 6.6 Feet

Style USB4

  • 100W fast charging with PD 3.1 and QC 4.0 support
  • 40Gbps bi-directional data transfer via USB4 Gen 3x2
  • 8K video output at 60Hz to a single display
  • 6 ft reversible USB-C to USB-C cable for flexible setups
  • Backwards compatible with 40W, 60W, 80W and 100W power profiles

One Cable for Power Data and 8K Display

This USB4 Gen 3x2 cable carries up to 100W of power at 20V, moves data at 40Gbps and drives a single 8K display at 60Hz or two 4K displays at 60Hz using two cables. The reversible USB-C male connectors support PD 3.1, PD 3.0 PPS, QC 4.0 and other fast-charge protocols so phones, laptops and accessories all charge at their maximum rated speed.

Replaces Slower Cables and Lower-Watt Chargers

If your current cable tops out at 60W or 80W it cannot deliver the full 100W a MacBook Pro 16'' or similar laptop may request under load. A 10Gbps or 20Gbps cable also caps file transfers well below the 2.8GB/s read and 2.1GB/s write this cable can sustain with compatible SSD enclosures. The jump is worth it when you need simultaneous high-power charging, 8K video and 40Gbps throughput in one 6.6FT run.

Check Your Charger Port and Device Limits

Your power adapter must support USB PD 3.1 Extended Power Range at 20V 5A to reach 100W; a 60W or 80W brick will simply negotiate its own lower ceiling. The host and peripheral must both implement USB4 Gen 3x2 or Thunderbolt 4 to hit 40Gbps and 8K60; older USB 3.2 or Thunderbolt 3 ports will fall back to their native speeds and resolutions. Cable length is fixed at 6.6FT so verify the reach suits your desk layout.

Questions about this item

What length and connector type does the 6.6FT cable use for a Thunderbolt 4 port?

The cable is 6.6FT long with USB C Male to USB C Male connectors, bi-directional and reversible for Thunderbolt 4 ports.

How do you enable 100W charging and 40Gbps data on this cable, and what step is often missed?

Use a 100W EPR PD 3.1 charger and a device that supports 100W load; the cable alone does not negotiate the higher power without both ends capable.

When will the cable need replacement if used at maximum 100W power delivery daily?

The cable is rated for extended power range up to 100W (20V/5A) and backwards compatible with lower wattages; replace if connectors become loose or physical damage appears.
