This 4-Port USB-C Hub with optional USB Power Delivery (PD) pass-through, expands the connectivity of a USB-C laptop. This hub features four USB 3.2 Gen 2 (10Gbps) Type-C ports, that support high-bandwidth USB peripherals. Support for USB PD enables charging of the host laptop and up to three USB peripherals by connecting a USB-C power source to the PD pass-through port. PD 3.0 features Fast Role Swap (FRS) to prevent USB data disruption when you switch power sources (USB-C power adapter to bus power). This allows you to charge the connected host device, as well as any devices connected to the three remaining USB-C ports. The 4-Port USB Hub is OS independent. It supports all operating systems including Windows, macOS, ChromeOS, iPadOS and Android. This adapter is plug-and-play, requiring no software or drivers.
