Compatibility & Setup Notes
This dock requires a Thunderbolt 3 host port — it will not deliver full function on a plain USB-C port without Thunderbolt. Both HDMI ouTPUts run 4K at 60Hz simultaneously on a Thunderbolt 3 laptop. It is bus-powered and offers no Power Delivery, so it does not charge the laptop — keep your own charger connected. Compatible with Thunderbolt 3 Windows and Mac systems.

Frequently Asked Questions
Singular Expert Insight
Choose this mini dock when Thunderbolt 3 dual-4K in a pocketable, bus-powered form is the priority — it is lighter and simpler than a full desktop dock, trading away Power Delivery and extra ports for portability. If you need charging pass-through or many USB ports at a fixed desk, a larger powered station fits better. Planning two screens? Browse our PC monitors, or compare more options in our docking stations range.
Buyer's Guide
Buy it if
You have a Thunderbolt 3 laptop and want a pocket dock driving two 4K 60Hz HDMI monitors plus Gigabit Ethernet and USB-A.
Skip it if
You need laptop charging (PD), a plain USB-C host, or many USB ports — this bus-powered TB3 dock offers none of those.
Also consider
A powered USB-C or Thunderbolt docking station with Power Delivery if you want charging and more ports at a fixed desk.
