SMUGDESK USB4 Cable 40Gbps 240W 8K 60Hz 4FT

SKU CH-VY19-Q94GY

USB-C cable delivering 240W charging, 40Gbps data and 8K 60Hz video over four feet

Cable Length 4 Feet

  • Charges at up to 240W with 48V/5A PD 3.1 power delivery
  • Transfers data at up to 40Gbps with USB4 Gen3x2 performance
  • Drives an 8K display at 60Hz for high-resolution video output
  • Works with Thunderbolt 4 and Thunderbolt 3 devices for broad compatibility
  • Reversible USB-C connectors enable simple bi-directional plug-in

Professional connectivity

This USB4 cable delivers 40Gbps bi-directional data transfer and up to 240W power delivery through a USB-C male-to-male connection. It supports 8K 60Hz video output for high-resolution displays and is backwards compatible with Thunderbolt 4 and Thunderbolt 3 devices. The 4FT length suits desktop and workstation setups requiring reliable, high-bandwidth links.

Build integration

The cable connects external SSDs, eGPU enclosures, and USB-C docking stations directly to a host port without adapters. Its Extended Power Range support handles 48V/5A charging for laptops up to 140W and scales down to lower power profiles including 180W, 100W, and 60W. Bi-directional, reversible connectors simplify cable routing in tight spaces.

Sustained operation

Real-world throughput reaches 2.8GB/s read and 2.1GB/s write speeds during large file transfers, maintaining performance beyond short bursts. The PD 3.1 and PPS compliance ensures stable voltage negotiation under continuous high-wattage loads. It is not for users needing longer runs beyond 4FT or those requiring legacy USB-A connectivity.

Questions about this item

What is the maximum data rate the cable can sustain when connected to a USB4 Gen3x2 device?

The cable supports up to 40Gbps bi-directional data transfer with USB4 Gen3x2 devices, with real-world read speeds up to 2.8GB/s and write speeds up to 2.1GB/s.

How much power can the cable deliver continuously during all-day use?

It delivers up to 240W at 48V/5A using PD 3.1 Extended Power Range, and remains backwards compatible with 180W, 140W, 100W and lower profiles.

Which charger and device are required to reach the full 240W charging capability?

A 240W EPR PD 3.1 charger and a device that accepts 240W input are both required; the cable alone does not increase the power beyond what the charger and device negotiate.
