That combination is marketed as 12 ports: 2× HDMI, VGA, Ethernet, PD USB-C, data USB-C, 3× USB-A, SD, TF, and 3.5 mm.
What it is good for
- Adding a 4K monitor (30 Hz) plus an older VGA display at the same time (mirror or extend, host-dependent).
- Keeping a laptop charged while using the dock (needs a 100W-capable USB-C charger into the PD port).
- Basic wired Ethernet where Wi-Fi is weak.
- Card readers and extra USB peripherals without swapping cables.
Limitations to know
- HDMI is 4K@30Hz, not 60 Hz. Fine for office/docs; less ideal for smooth 4K video or gaming.
- Ethernet is 100 Mbps, not Gigabit.
- USB is 5 Gbps USB 3.0, not 10 Gbps USB 3.2 or Thunderbolt.
- Dual-display combo is 4K HDMI + 1080p VGA, not two 4K outputs.
- Your laptop/tablet must support USB-C DisplayPort Alt Mode and PD charging for video + power to work together.
There is a different Green Lion “12-in-1 USB-C Hub 4K” (GN12IN1HUB) with a different port mix; the “4K HDMI Ethernet” naming and GN12N1CHUBGY match the dual-HDMI + VGA + 100 Mbps Ethernet model above.
