The CalDigit Thunderbolt 3 Mini-Dock is a portable docking solution for users who need additional connectivity options in a small and lightweight form factor. Unlike other smaller USB-C-based hubs, the CalDigit Mini-Dock utilizes a full 40 Gbps Thunderbolt 3 connection, allowing for the connection of two 4K displays. Additionally, it features a full-speed USB 3.0 Type-A port and a Gigabit Ethernet port for fast network access. The CalDigit Thunderbolt 3 bus-powered Mini-Dock is available in two variants: a Dual DisplayPort 1.2 model and a Dual HDMI 2.0 model.
