Thunderbolt 4 cable, 40Gbps and 240W

This Thunderbolt 4 cable carries 40Gbps data and up to 240W power over a USB-C to USB-C link. It suits professionals who need fast storage transfers and high-watt charging from a single cord. The grey, five-foot length fits typical desk or dock setups without excess slack.

40Gbps bandwidth, 240W headroom

The cable handles 40Gbps theoretical throughput, moving 2.5GB files in roughly one second with real-world reads up to 2.8GB/s and writes up to 2.1GB/s. It delivers 240W (48V/5A) when paired with a compatible charger, covering phones through gaming laptops. Bandwidth drops to USB 3.2, 3.1 or 2.0 speeds on legacy ports, and charging falls back to the host’s lower limit.

Male-to-male USB-C, grey finish

Male-to-male USB-C connectors plug directly into Thunderbolt 3, Thunderbolt 4, USB4 and USB-C hosts, docks, storage and displays. The cable drives one 8K or 5K display at 60Hz, or dual 4K at 60Hz when the source supports DisplayPort Alt Mode. Build quality targets repeated insertion cycles in daily docking and charging workflows.

Questions about this item

Will this 40Gbps Thunderbolt 4 cable work with my older USB 3.2 and USB 2.0 devices?

Yes, it is backward compatible with USB 3.2, 3.1 and 2.0 speeds and devices, so your existing peripherals will connect and operate at their rated performance.

How can I verify the cable is delivering 240W charging and 40Gbps data after I plug it in?

Use a USB-C power meter to confirm up to 48V/5A negotiation, and run a large file transfer to a high-speed drive; sustained reads near 2.8GB/s and writes near 2.1GB/s indicate full throughput.

Does the 5ft grey cable include a 240W charger or video adapters, or must I buy those separately?

The box contains only the USB-C to USB-C cable; a compatible 240W charger and any DisplayPort Alt Mode source or display adapters are sold separately.
