This article covers StarTech.com 50cm USB-C.

Overview

The StarTech.com USB31CCV50CM is a 50cm USB-C to USB-C cable supporting USB 3.2 Gen 2 at 10Gbps. It delivers up to 100W (5A) Power Delivery 3.0 for fast charging and supports DisplayPort Alt Mode 1.4 for video output up to 8K60Hz — all through a single cable. This short cable is ideal for tidying up your desk by connecting a laptop to a monitor or linking a docking station to peripherals without excess slack.

Connectivity & Compatibility

This cable features USB Type-C male-to-male connectors and works with any device equipped with a USB-C port. Compatible devices include MacBook Air/Pro, Surface Book, ThinkPad X1 Carbon, iPad Pro, iPhone 15 series and later, Samsung Galaxy S8 and later, and Google Pixel 5. It also works with portable monitors such as ASUS ZenScreen and ProArt series. Thunderbolt 3/4 ports are fully compatible, ensuring broad usability across different setups.

Product Info

Released around fall 2021, the USB31CCV50CM is available on for approximately ¥2,449 (tax included). The manufacturer provides a 2-year warranty. The package includes only the cable itself, with no additional accessories. In the market, this cable sits in the mid-range tier — it offers 10Gbps data transfer and 100W PD support at a reasonable price, outperforming basic charging cables while costing less than premium Thunderbolt 4 cables.

Best Use Cases

This cable is perfect for users who keep their laptop and monitor close together on a desk. The 50cm length prevents cable clutter and keeps the workspace neat. It is also ideal for connecting a USB-C hub or docking station to a laptop, providing both high-speed data transfer for external SSDs and power delivery for the laptop through a single cable. Finally, mobile workers who frequently travel or work in cafes will appreciate the short, portable form factor — it easily fits in a bag and works well with power banks and portable monitors.

Things to Consider

The 50cm length is excellent for close-range connections but too short for linking devices placed far apart, such as a floor-standing PC tower to a desk monitor. To achieve the full 10Gbps speed, both connected devices must support USB 3.2 Gen 2; older USB 3.0 or USB 2.0 devices will operate at reduced speeds. Additionally, while the cable supports 100W PD charging, the actual charging power depends on the charger's output capability. Always verify the specifications of your devices and charger to get the most out of this cable.
