Product Features
Technical Overview
This USB-C hub implements the USB 3.2 Gen 2 specification, delivering theoretical data transfer rates up to 10Gbps—twice the speed of USB 3.2 Gen 1 and ten times faster than USB 2.0. The hub can operate in bus-powered mode for basic connectivity needs or connect to an external USB-C power adapter (not included) to enable the full 100W power delivery pass-through capability.
When connected to a compatible power adapter, the hub reserves 15W for its own operation while passing up to 85W to the host computer and downstream devices. Each downstream port can deliver up to 7.5W for charging smartphones, tablets, or other USB-powered accessories. The hub maintains backward compatibility with USB 3.1/3.0 devices while providing full USB-C connectivity for modern laptops, tablets, and convertibles.
Relevant factors for this section include Host Interface, Total Number of USB Ports, Number of USB 3.2 Ports. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

FAQ
What is the data transfer speed of this USB-C hub?
This hub supports USB 3.2 Gen 2 with data transfer speeds up to 10Gbps. This provides twice the throughput of USB 3.2 Gen 1 (5Gbps) and enables fast file transfers between connected devices. The speed applies to all four downstream USB-C ports when connected to compatible host devices and peripherals.
How does the 100W power delivery pass-through work?
When connected to a compatible USB-C power adapter (not included), the hub can pass through up to 100W of power. The hub reserves 15W for its own operation, leaving up to 85W available to power the host computer and charge connected devices. Each downstream port can deliver up to 7.5W for charging smartphones, tablets, or other accessories.
