Thunderbolt 3 hub for MacBook Pro

This Thunderbolt 3 certified hub expands a MacBook Pro 13 or 15 with seven additional ports in a compact Space Gray enclosure. It adds one Thunderbolt 3 USB-C port, one USB-C 3.1 Gen 1 port, two Type-A 3.1 Gen 1 ports, an HDMI output, plus SD and Micro SD card slots. The hub draws power from the host connection and requires no external driver installation.

Aluminium build with integrated cable

The aluminium housing measures 0.4 inches high by 1.1 inches wide and weighs approximately 1.44 oz, making it suitable for mobile workstations. A short captive Thunderbolt 3 cable connects directly to the host, reducing desk clutter and eliminating loose cable management. Ports are arranged along both long edges for straightforward access to peripherals and memory cards during daily use.

Replaces multiple single-function dongles

This hub consolidates separate video, data and card-reader adapters into one device, cutting the number of items carried between home and office. The jump is worthwhile when a workflow demands simultaneous 4K@30Hz display output, 40Gbps Thunderbolt throughput and UHS-I card ingest without swapping cables. Users needing only occasional USB-A or HDMI connectivity may find a simpler adapter sufficient.
