8-in-1 USB-C Dock with Dual 4K HDMI

The Aibilangose 5550 expands a single USB-C or Thunderbolt 3 port into eight connections: two HDMI outputs at 4K 30 Hz, USB 3.0, USB 2.0, USB-C data, SD and TF card readers, and 100 W Power Delivery passthrough. It is built for Windows laptops that support DP Alt Mode and need two extended displays without driver installation.

Windows users needing MST extended desktops

Mac users are limited to SST mirror mode, so the second HDMI shows the same image rather than an independent workspace. Buyers whose laptops lack video-capable USB-C or Thunderbolt 3 ports cannot use the HDMI outputs at all. The USB-C data port carries no power or video, so it cannot replace the host port for charging or a third display.

Driver-free setup with power caveats

Plug the adapter into a supported port and both monitors appear immediately on Windows; macOS mirrors automatically. The unit draws charging power from your laptop’s own supply — it adds no power itself — so an under-powered charger causes unstable video. The SD and TF slots share one controller and cannot operate simultaneously.

Questions about this item

Does my laptop need a USB-C port that supports video output for the 5550 to drive two 4K@30Hz HDMI monitors?

Yes, the adapter requires a fully functional USB-C or Thunderbolt 3 port with DP Alt Mode to enable both HDMI outputs at 4K@30Hz.

Will the 5550 extend two different screens on macOS the way it does on Windows?

No, macOS only supports SST mirror mode so both HDMI ports show the same image; Windows can use MST for true extended desktop.

How can I confirm the 5550 is delivering up to 85W of pass-through power to my laptop after connecting everything?

Check your laptop's battery indicator — it should show charging while the adapter's PD port is connected to a 100W power source.
