Many USB-C hubs include HDMI (often supporting 4K), legacy video outputs such as VGA, an Ethernet (RJ45) port, multiple USB-A ports, SD and microSD card readers, a USB-C power‑delivery input for charging, and sometimes a 3.5mm audio jack.
Hubs commonly provide USB 3.0 speeds (around 5 Gbps) on some ports and USB 2.0 speeds (around 480 Mbps) on others. Ports are often labeled with their supported speed.
Many hubs include USB-C Power Delivery passthrough and can support up to 100W of charging. Some product listings also specify PD 3.0 compliance alongside that 100W capability.
Some USB-C hubs include both SD and microSD card slots. Capabilities vary by model; for example, at least one model in this set supports SD/microSD 3.0 (UHS‑I) with read speeds up to about 104 MB/s.
Some hubs are bus‑powered (drawing power from the host) while also supporting Power Delivery passthrough. Whether an external power adapter is required depends on the specific model and its PD capabilities.
Some hubs include a 3.5mm auxiliary jack for wired headphones or speakers, while others provide audio only through the HDMI connection.
