What this cable does

The BUCIER USB 4.0 Type-C extension cable adds one foot of reach while preserving the full 40Gbps bandwidth of the host port. It carries 240W of power at 48V and 5A, so laptops, phones and tablets charge at their maximum rate. The male-to-female layout lets you extend an existing cable or dock without replacing it.

Installation notes

Plug the angled male end into the host or dock and connect your device to the straight female end; no drivers or configuration are required. The up-and-down angle helps the connector sit flush against the chassis, reducing strain on the port. The only common issue is expecting Thunderbolt speeds from a host that only supports USB 3.0 — the cable will still work, but bandwidth drops to the host limit.

Practical limits of USB 4.0

The interface tops out at 40Gbps, with real-world reads around 2.8GB/s and writes near 2.1GB/s when both ends support the standard. Video output reaches 8K at 60Hz or dual 4K displays, though dual monitors need two cables. Actual throughput always depends on the host controller, the device and the quality of the connection.

Questions about this item

How do I confirm the cable is delivering 40Gbps data and 240W power after connecting it?

Check the host device's USB controller panel or Thunderbolt status screen; it should report a 40Gbps link and 48V/5A power contract when both ends support USB 4.0.

What connectors and accessories are included with the 1ft USB 4.0 extension cable?

The box contains the straight USB-C female to angled USB-C male cable only; no extra adapters or power bricks are supplied.

Should I choose this 40Gbps USB 4.0 cable or a slower 3.0 version for 8K@60Hz video and 240W charging?

Only the USB 4.0 model rated at 40Gbps and 48V/5A supports 8K@60Hz output and full 240W power delivery; USB 3.0 cannot handle either.
