Thunderbolt 5 Cable 6.6 ft

This Thunderbolt 5 cable connects laptops, docks and high-speed SSDs over USB-C. It suits professionals who need maximum bandwidth and power delivery for demanding workflows. The 6.6 ft length gives flexible placement on a desk or in a rack. It is not for users who need longer runs beyond the supplied length.

80 Gbps bandwidth and 240 W charging

Data moves at up to 80 Gbps, eight times the rate of standard USB-C cables. The cable delivers up to 240 W of power, exceeding earlier 60 W and 100 W limits. Video output reaches 16K at 60 Hz or dual 8K at 60 Hz when the host supports DisplayPort Alternate Mode. Backward compatibility covers USB 3.2, 3.1 and 2.0 speeds.

USB-C connectors with broad device support

USB-C plugs on both ends fit Thunderbolt 3 and 4 hosts, MacBook Pro, iMac, MacBook Air and Windows laptops. The connectors also work with docking stations and high-speed storage peripherals. No active electronics are mentioned, so signal quality depends on the 6.6 ft passive design. Buyers needing active repeaters for greater distance should look elsewhere.

Questions about this item

Should I choose the 1.6 ft or the 6.6 ft version for my desk setup?

The 6.6 ft length gives comfortable reach between a laptop and a dock on a typical desk, while the 1.6 ft version suits tight spaces or travel bags where excess cable would get in the way.

What does the 80 Gbps figure mean when I plug this cable into my laptop and an external SSD?

It sets the maximum theoretical bandwidth; real-world transfer speeds will be lower and depend on the drive, the controller and the host port, but the cable itself will not be the bottleneck.

How does the Thunderbolt interface limit the 240 W charging claim in everyday use?

The cable can carry up to 240 W, but the actual power delivered is negotiated between the charger and the device, so you will only see the full rate if both ends support that level.
