Dual 4K 60Hz Output

This adapter connects a USB-C or Thunderbolt 3 host to two external monitors via HDMI, each supporting resolutions up to 3840x2160 at 60Hz. A 3.5mm audio jack lets you plug headphones or speakers directly into the hub. A USB-C Power Delivery pass-through port accepts up to 100W from your original charger to keep the laptop powered while you work.

Windows Extend vs Mac Mirror

Windows systems can drive two independent displays using MST, giving you extra desktop space for multitasking. macOS is limited to mirror mode, so both screens show the same image. The compact, bus-powered design suits mobile professionals who need dual-screen productivity on the move.

100W PD Pass-Through

The single specification that decides fit is the 100W USB-C charging pass-through; your laptop must support USB Power Delivery over its USB-C port to charge while the adapter drives both displays. Without PD support on the host port, the hub will still output video but cannot supply power to the computer.

Questions about this item

What USB-C port does the Jansicotek adapter need to fit?

It plugs into a single USB-C or Thunderbolt 3 port on the host device.

Which driver step is often missed when setting up dual monitors on Windows?

Windows requires MST mode to extend two different screens; enable it in display settings or consult the user guide.

What power source keeps the adapter running during extended use?

Connect the laptop's original charger to the 100W USB-C PD port; the adapter draws no separate power.
