SMUGDESK

SMUGDESK USB4 Cable 1.6ft 40Gbps 240W PD 3.1 QC 4.0 Thunderbolt 3 8K@60Hz

SKU CH-TMRJ-6D4TK

A 1.6 ft USB-C cable carrying 40 Gbps data, 240 W PD 3.1 power and 8K 60 Hz video for Thunderbolt 3 devices

Cable Length 1.6 Feet

  • 240W PD 3.1 charging powers demanding laptops with a single cable
  • 40Gbps USB4 Gen 3x2 speed moves large files in seconds
  • 8K@60Hz video output drives high-resolution displays without lag
  • 6ft length keeps desk setups tidy and signal quality high
  • Bi-directional USB-C connectors plug in either way for quick connections

One Cable for All Devices

This 1.6ft USB4 cable carries up to 240W of power and 40Gbps of data between any USB‑C ports. It supports PD 3.1, PD 3.0 PPS, PD 2.0, QC 4.0, QC 3.0, AFC, SCP and FCP protocols. The bi‑directional, reversible connectors work with laptops, phones, tablets, monitors and external SSDs.

Sustained 240W Delivery

When paired with a 240W EPR PD 3.1 charger and a compatible device, the cable maintains 48V at 5A continuously rather than only in short bursts. Extended Power Range support keeps the connection stable at 240W, 180W, 140W, 100W, 65W and lower levels without thermal throttling or voltage drop.

40Gbps and 8K@60Hz Limits

The USB4 Gen 3x2 interface tops out at 40Gbps bi‑directional throughput, so larger files move at that ceiling and not beyond. Video output reaches 8K at 60Hz over Thunderbolt 3 ports, but higher refresh rates or resolutions exceed the cable’s rated bandwidth.

Questions about this item

Does the 1.6 ft cable stay cool while delivering 240 W continuously?

The cable is rated for Extended Power Range up to 48 V and 5 A, so it handles 240 W without overheating during all-day use.

What charger and device must I already own to reach 240 W?

You need a 240 W EPR PD 3.1 charger and a device that accepts 240 W input; lower-power chargers will fall back to their supported wattage.

Will this cable drive an 8K monitor at 60 Hz from my Thunderbolt 3 laptop?

Yes, it supports 8K at 60 Hz video output through Thunderbolt 3 ports.
