Short white USB-C cable with straight connectors, 1.6ft length

SMUGDESK

SMUGDESK 240W USB4 cable 1.6ft 40Gbps 8K 240W

SKU CH-ZHTB-ZCYA5 MPN 240W

A 1.6ft USB-C cable delivering 240W charging, 40Gbps data transfer and 8K video output

Cable Length 1.6 Feet

Model 240W

  • Charges up to 240W with PD 3.1 48V/5A
  • Transfers data at 40Gbps USB 4.0 speed
  • Drives single 8K@60Hz or dual 4K@60Hz displays
  • Works with Thunderbolt 4, 3 and USB 3.2 down to 2.0
  • Built-in safety resistor keeps current stable at 5A

What the cable delivers

This USB4 cable carries up to 240W of power at 48V/5A, transfers data at up to 40Gbps and drives a single 8K display at 60Hz or dual 4K displays at 60Hz. It is built for users who need maximum charging speed, high-bandwidth file moves and top-tier video output from one 1.6ft connection.

Sustained-load behaviour

The integrated safety resistor keeps current stable at 5A during extended charging sessions, preventing disturbance that can damage equipment. Data throughput remains at the rated 40Gbps only when both host and peripheral support USB4 Gen3; otherwise the link falls back to 20Gbps on Gen2 ports.

Check before ordering

Verify that your charger, laptop, dock or SSD enclosure supports USB Power Delivery 3.1 at 240W and USB4 Gen3 for full 40Gbps speed. Confirm the host port can output 8K@60Hz or dual 4K@60Hz video, and ensure the 1.6ft length reaches between your devices without strain.

Questions about this item

Does the 1.6ft cable get warm or draw extra power when running a 240W charge all day?

The cable is rated for 48V/5A maximum current with a built-in safety resistor that keeps current stable at 5A, so it handles continuous 240W charging without overheating or excess power draw.

What must my charger and device both support to reach 240W through this cable?

Both the charger and the device need USB Power Delivery 3.1 with the extended power range (48V/5A); the cable is backward compatible with PD 3.0 but will only deliver up to the lower standard's limit.

Will this cable run at 40Gbps with my Thunderbolt 3 dock and older USB 3.2 laptop?

The cable supports up to 40Gbps with USB4 or Thunderbolt 4 hosts, drops to 20Gbps with USB 3.2 Gen 2 ports, and works at the highest speed the connected ports allow.
