SKU CH-SHE0-C6ZZ4

USB-C cable delivers 240 W charging, 80 Gbps Thunderbolt data and 16K 60 Hz video in one metre

Cable Length 1m

  • 240 W power delivery charges laptops fast
  • 80 Gbps Thunderbolt 5 speed moves large files quickly
  • 16K at 60 Hz gives ultra-sharp single-display clarity
  • Dual 8K at 60 Hz expands workspace across two monitors

Thunderbolt 5 cable for high-power charging

This USB-C to USB-C cable supports up to 240 W power delivery at 48 V and 5 A under the USB PD 3.1 specification. It is built for users who need a single cable to charge power-hungry laptops and workstations quickly while protecting devices from overheating. The one-metre length suits desk and dock setups where the power source sits close to the machine.

Data throughput and display bandwidth

Rated for 80 Gbps with Thunderbolt 5 compatibility, the cable moves large files such as a 20 GB 4K film in under a second when both host and peripheral support the speed. It drives a single 16K display at 60 Hz or dual 8K monitors at 60 Hz, and can also run two 4K screens at 60 Hz simultaneously. Actual transfer rates depend on the connected equipment.

Build integration and device support

The cable connects Thunderbolt 5, Thunderbolt 4 and Thunderbolt 3 hosts to docks, hubs, external SSDs and displays without extra adapters. Its USB 4.0 Gen 4 design keeps the signal clean over the full length, freeing up ports on the computer for other peripherals. Buyers who need longer reach or legacy USB-A connectivity will need a different solution.

Questions about this item

How do I connect the 1 m USB C to USB C cable so the 240 W PD 3.1 charging works?

Plug each end fully into a USB C port on both the charger and the device; the cable negotiates 48 V at 5 A automatically, but the charger and device must both support PD 3.1 for the 240 W rate.

Will the cable’s 80 Gbps Thunderbolt 5 performance degrade over time?

The passive copper construction has no active electronics to wear out, so data-rate capability stays constant; only physical damage to the connectors or cable body would reduce throughput.

What stops me from hitting 80 Gbps sustained throughput in daily use?

The 80 Gbps ceiling is a link-rate maximum; real-world sustained speed is limited by the host controller, drive controller, and thermal throttling of the connected SSD or dock.
