Rocstor USB-C 12-in-1 Docking Station 100W PD 2x HDMI VGA 4x USB-A Gigabit RJ45 3.5mm Audio SD/TF

SKU CH-AQAG-8WJR2

Connects a USB-C laptop to two HDMI displays, VGA, four USB-A ports, gigabit Ethernet, audio and SD cards while delivering 100 W pass-through power

  • 12 ports expand one USB-C into video, data, network and audio
  • Dual HDMI plus VGA drive three external displays from a single laptop
  • Four USB-A ports including two 3.2 Gen 1 at 5 Gb/s
  • Gigabit RJ45 adds stable wired networking without extra dongles
  • 100 W Power Delivery pass-through charges the host while the dock runs

Connectivity for USB-C Laptops

The Rocstor 12-in-1 docking station adds dual HDMI, VGA, Gigabit Ethernet, four USB-A ports, SD and microSD slots plus a 3.5 mm audio jack through a single USB-C cable. It suits professionals who need a permanent desk hub for multi-monitor work and wired networking without opening the laptop chassis. Power Delivery pass-through keeps the host charged while every peripheral stays connected.

Upgrade from Basic Dongles

This unit replaces single-port adapters that only offer one video output or lack wired Ethernet and card readers. The jump is worth it when you routinely drive two external displays at once, transfer files from camera cards, or require a stable Gigabit link for large backups. Basic hubs without 100 W pass-through also force you to choose between charging and peripherals.

Check Host Port and Display Limits

Verify that your laptop's USB-C port supports video alt mode and Power Delivery input; a data-only port will not drive the HDMI or VGA outputs. Confirm the graphics subsystem can handle the number of external screens you plan to attach, as some integrated controllers limit output to one or two displays. Ensure the supplied cable reaches your desk layout without strain.

Questions about this item

Does the 100 W power-delivery pass-through port require its own charger to run the dock and charge the laptop?

Yes — connect the laptop's USB-C charger to the pass-through port; the dock draws its operating power from that same supply while delivering up to 100 W to the host.

Which video ports can be active at the same time for a triple-monitor setup?

Both HDMI outputs and the VGA port can run together, giving three external displays from a single USB-C connection.

How often should the SD and microSD card slots be cleaned to keep reliable contact?

A quick blast of compressed air every few months removes dust that can interrupt the card-reader pins.
