LORDWORLD USB 4 Cable 6.6 ft 40Gbps 240W

SKU CH-6989-4KR6D

A 6.6 ft USB 4 cable delivering 40 Gbps data transfer and 240 W PD 3.1 charging for Thunderbolt 4/3, USB 4 and earlier devices

  • Drives one 8K@60Hz or dual 4K@60Hz displays with daisy-chain support
  • Transfers data at 40Gbps, moving 2.6GB in one second
  • Charges at 240W (48V/5A) with PD 3.1 Extended Power Range
  • Works with Thunderbolt 4/3, USB 4 and USB 3.2 devices
  • PCIe transfer reaches 3000MB/s for eGPU and fast SSD workflows

6.6 ft USB 4 cable for Thunderbolt 4 workflows

This 40Gbps cable serves users who need 240W charging and high-resolution video on a single 6.6 ft link. It supports Thunderbolt 4, Thunderbolt 3 and USB 4 devices including laptops, docking stations, eGPU enclosures and high-speed SSDs. The 40Gbps bandwidth handles 8K or dual 4K display output alongside PCIe data traffic.

Plug-and-play installation

Connect the cable to a USB-C port that supports DP Alt Mode for video output; without that feature the link will carry data and power only. The cable is backward compatible with USB 3.2 Gen 2x2, Gen 2, Gen 1 and 2.0 hosts, so it works immediately on older ports at their native speeds. No drivers are needed for basic operation.

Verify port capabilities

Confirm that your host port delivers DP Alt Mode if you plan to drive an 8K or 4K@144Hz display. For 240W charging both the power adapter and the device must support PD 3.1 Extended Power Range at 48V/5A. Dual 4K@60Hz operation requires two separate cables, and daisy-chain topology depends on the host controller implementation.

Questions about this item

How can I verify the cable is delivering 40Gbps after connecting it?

Check that the link negotiates 40Gbps in your OS settings and confirm PCIe transfers reach 3000MB/s.

What comes in the box and what must I buy separately?

The box contains the 6.6 ft USB 4 cable only; a 240W charger and Thunderbolt 4 host are required for full performance.

Which version should I choose for one 8K display versus dual 4K monitors?

One cable drives a single 8K@60Hz or 4K@144Hz display; dual 4K@60Hz requires two cables and a host with DP Alt Mode.
