11-in-1 Thunderbolt 3 USB-C Docking Station

This 11-in-1 Thunderbolt 3 USB-C docking station adds triple external display outputs, wired networking and legacy ports to a single laptop connection. It suits mobile professionals who need a compact hub for multi-monitor productivity at a desk or on the move.

Triple Display with Included Adapters

Two supplied DisplayPort-to-HDMI adapters let you drive two HDMI monitors and one VGA screen simultaneously on Windows, while macOS is limited to mirror or dual-mode by the operating system. The Gigabit Ethernet port provides a stable 1000 Mbps wired link and the PD input accepts up to 100 W to charge the host laptop.

Thunderbolt 3 Bandwidth and Protocol Limits

Thunderbolt 3 bandwidth caps both HDMI ports at 4K 30 Hz and the VGA output at 1080p 60 Hz, so high-refresh gaming or 4K 60 Hz workflows are not supported. The USB-C PD port handles power only and carries no data, and macOS users cannot span three independent external screens regardless of the dock’s hardware.

Questions about this item

Will the 100W PD charging port need a separate power adapter over time?

The PD port accepts up to 100W input from your laptop's own charger; no extra adapter is required unless your original supply fails.

What limits triple 4K output to 30Hz on each HDMI port?

The dock's HDMI 1 and HDMI 2 are both specified at 3840x2160 30Hz, so sustained triple 4K use hits that refresh ceiling first.

How hot or loud does the unit get when all ports and three monitors run all day?

The manufacturer highlights low power consumption chips and the dock has no fan, so it runs silently with only modest warmth during continuous use.
