SMUGDESK

SMUGDESK USB4 Cable 240W 40Gbps 8K 5 ft

SKU CH-85P2-CFBNR

A USB-C cable delivering 240W charging, 40Gbps data and 8K video in a 5 ft length

Cable Length 5 Feet

  • 240W Power Delivery charges laptops fast
  • 40Gbps data transfer moves large files quickly
  • 8K 60Hz video drives high-res displays
  • Thunderbolt 3 and 4 compatible with earlier USB-C
  • 6 ft cable reaches desktop peripherals

One Cable for Every USB-C Device

This USB4 cable handles charging, data and video through a single USB-C to USB-C connection. It works with laptops, tablets, phones, monitors and docking stations that use a USB-C port. Backward compatibility covers USB 3.2, 3.1 and 2.0 hosts and peripherals. Buyers who need legacy USB-A or micro-USB connectors cannot use this cable without adapters.

240W Charging and 40Gbps Data in a 5 ft Length

The 1.6 metre cable delivers up to 240W (48V 5A) Power Delivery 3.1 when paired with compatible GaN chargers rated from 18W to 170W. Data moves at 40Gbps, twice the throughput of earlier USB-C thunderbolt cables. Thunderbolt 3 and 4 hosts and devices are supported. The fixed length suits desktop docking but may be short for users who need longer runs across a room.

8K Video and Dual 4K Without Extra Adapters

One 8K display at 60Hz or two 4K displays at 60Hz are driven directly from the cable when the host supports DisplayPort Alternate Mode. No separate video dongles are required for compatible MacBook, iPad, Surface, Samsung Galaxy or Chromebook devices. Buyers whose USB-C ports lack Alt Mode video output will not get a picture from this cable alone.

Questions about this item

What data rate does the USB4 cable support, and what does that cap in practice?

The cable handles 40 Gbps, which is the full USB4 Gen 3×2 speed ceiling for both host-to-device and device-to-host traffic.

What physical length and connector style does the 5 ft cable use?

It measures 1.6 m (5 ft) end-to-end with USB-C plugs on both sides, so it reaches across a desk without needing an extender.

How do I get 240 W charging to work, and what step do people miss?

Pair the cable with a PD 3.1 charger rated for 48 V / 5 A (e.g. 140 W or 170 W GaN adapter); the cable alone cannot negotiate 240 W if the brick tops out at 20 V.
