What this hub does
This nine-port USB-C hub adds three USB-A 3.0 ports, one USB-C 3.0 port, one USB-A 2.0 port, an SD/TF card reader, a 4K HDMI output and a 100 W power-delivery pass-through to a single Type-C socket. It is aimed at laptop users who need legacy peripherals, external displays and charging from one compact adapter.
Who it suits and who it doesn't
The hub suits owners of Windows, macOS, Chrome OS, Linux or Android devices that support DisplayPort Alt Mode and power delivery over USB-C. It will not help buyers whose Type-C ports carry only data or charging, or builders who need more than one video output or wired Ethernet connectivity.
What to check before ordering
Confirm that your host port supports DP Alt Mode for 4K 30 Hz video and PD 3.0 for up to 100 W input so the hub can charge the laptop at 87 W. Verify the 20 cm captive cable reaches your port without strain and that the aluminium-and-ABS body fits your desk space.

Questions about this item
My laptop has only a single USB-C port — can this hub pass 100 W power through to keep it charged while I use the other ports?
The hub accepts up to 100 W input and delivers a maximum of 87 W to the host, so a single USB-C port can charge the laptop and run peripherals simultaneously.
Will the HDMI output drive a 4K monitor at 30 Hz if my older laptop only supports 1080p over USB-C?
The HDMI port outputs up to 4K at 30 Hz and is downward compatible with 1080p, 1080i and 720p, so it will match the highest resolution the host can provide.
After plugging everything in, how can I confirm the three USB 3.0 Type-A ports are running at 5 Gbit/s?
Connect a USB 3.0 flash drive and check the reported link speed in your OS device manager or system profiler; it should show 5 Gbit/s SuperSpeed operation.
