Cable USB4 Gen 2x2 USB-C Unitek C14100BK-0.8M — 0,8 m, USB-C a USB-C, 40 Gbit/s, negro

Unitek C14100BK-0.8M is a 0.8 m USB-C to USB-C cable that implements USB4 Gen 2x2 connectivity with up to 40 Gbit/s bidirectional throughput. The cable is designed for high-speed data transfers, video output and device charging between modern USB-C hosts, docks, external drives and hubs. The black jacket and compact 0.8 m length make it suitable for desktop setups, portable workstations and short-reach connections where reliable high bandwidth and power delivery are required.

Advantages

This USB4 cable supports up to 40 Gbit/s transfer rates and is backward compatible with Thunderbolt 3, USB 3.2 Gen 2 and earlier USB standards, enabling fast file transfers and broad device support. It provides USB-C Power Delivery up to 100 W (20 V / 5 A) for charging laptops and other PD-capable devices when used with a suitable PD adapter. The cable also supports video over USB-C, enabling connection to 8K@60Hz or dual 4K displays when the connected devices and host support USB4, Thunderbolt or DisplayPort Alternate Mode. The compact 0.8 m length reduces cable clutter and is convenient for portable and desk setups.

Suitable for

• High-speed file transfers between laptops and external SSDs
• Connecting USB4 or Thunderbolt-compatible docks and hubs
• Video output to an 8K display or dual 4K monitors (when devices support required modes)
• Charging laptops and PD-capable devices up to 100 W with an appropriate power adapter

Key specifications

• Connector type: USB-C to USB-C
• USB version: USB4 Gen 2x2 (up to 40 Gbit/s)
• Cable length: 0.8 m
• Power Delivery: up to 100 W (20 V / 5 A) supported
• Video support: supports DisplayPort Alt Mode for up to 8K@60Hz or dual 4K depending on host/device capabilities
• Colour: black

How to use

Connect one USB-C end to a compatible host device (laptop, dock or PC) and the other end to a USB-C peripheral such as an external SSD, monitor or charging adapter. To achieve maximum data rates and video output, ensure both connected devices support USB4 Gen 2x2, Thunderbolt 3/4 or the required DisplayPort Alt Mode. For high-power charging, pair the cable with a PD-capable power adapter; charging speed will depend on the adapter and the host device's supported PD profile.

Recommendations

Use this cable for short-reach, high-bandwidth connections where 40 Gbit/s throughput or up to 100 W PD is needed. To guarantee the expected video and data performance, verify that both devices and any intermediary hubs or docks explicitly support USB4, Thunderbolt or DisplayPort Alternate Mode. Avoid excessive bending near the connectors and keep the cable clear of heat sources to maintain optimal lifespan and performance.
