Universal Thunderbolt 5 Dock with Three Thunderbolt 5 Ports, One M.2 SSD Slot, One 10Gb Ethernet Port, Two Display Connection Ports, Nine 10 Gbps USB 3 Ports, and More...

Presenting the Echo 21 Thunderbolt 5 SuperDock — our most powerful and expandable dock ever — featuring superfast SSD internal storage capability and built-in 10GbE networking. Transform a single cable connection from your computer into two Thunderbolt 5 peripheral ports, one NVMe SSD slot, one 10Gb Ethernet port, nine 10 Gbps USB ports, two video output ports, and more! With 80 Gbps of bi-directional data speed — twice as fast as Thunderbolt 4 — and 120 Gbps for higher display bandwidth, you'll revolutionize your productivity.

Your Peripherals and Power Your Laptop with One Thunderbolt 5 Cable
Echo 21 Thunderbolt 5 SuperDock links connected Thunderbolt devices, monitor(s), USB peripherals, powered speakers, and Ethernet cable to your computer with a single Thunderbolt 5 cable. Got a laptop? Keep its power adapter in your bag — the SuperDock will power it with 140W of charging power. When it’s time to leave, just unplug the Thunderbolt cable, grab your computer, and go.

Expansion Slot
Add up to 8TB of high-speed SSD storage (SSD sold separately) directly inside the dock —no external storage device required. Installation is simple: remove the bottom panel, insert the SSD, and secure the cover. Once installed, access and transfer data at up to 3300 MB/s. Ideal for pro content creation, application storage, large media libraries, and Time Machine backups.

HDMI and DP Display Support
Echo 21 Thunderbolt 5 SuperDock features video output ports for HDMI and DisplayPort displays, enabling you to connect either an up to 8K* @60Hz HDMI monitor or a 4K @144Hz DisplayPort monitor.

10GBASE-T Access
Echo 21 Thunderbolt 5 SuperDock supports demanding workflows with built-in 10 Gigabit Ethernet, enabling connection to 10GbE infrastructure using cost-effective Cat 6 or Cat 6A copper cabling (up to 55 or 100 meters, respectively) — eliminating the need for a separate adapter.

Delivering up to 10x the performance of Gigabit Ethernet, the dock also supports 5 Gbps, 2.5 Gbps, 1 Gbps, and 100 Mbps link speeds when connected to switches or NAS devices without 10GbE support, using standard Cat 5e (or better) cabling.

Downstream Thunderbolt 5 Ports for Comprehensive Connectivity
Echo 21 Thunderbolt 5 SuperDock incorporates three Thunderbolt 5 ports. One connects to and powers your computer — ideal for laptops with only one or two Thunderbolt ports, since it handles charging and data through a single connection. The other two support Thunderbolt 5, 4, and 3 devices — as well as USB4 and USB 3 peripherals — and each provides 15W for demanding bus-powered devices. If supported by your computer, you can also connect one, two, or even three additional displays.

10 Gbps USB-A and USB-C Ports
Echo 21 Thunderbolt 5 SuperDock delivers powerful USB 3 connectivity with four 10 Gbps USB-A ports, and five 10 Gbps USB-C charging ports — including two on the front, two on the back, and a front 15W USB-C charging port. All ports support super-fast 10 Gbps USB NVMe SSDs at full speed.

Echo 21 doesn’t skimp on power either — each port provides 7.5W (or 15W) to ensure that drives with higher peak power requirements mount and operate reliably. An added benefit of the USB-C ports is they support device charging even when the computer is off, asleep, or disconnected.

Thunderbolt Certified for Mac, Windows, Chromebook, and iPad Pro
Echo 21 Thunderbolt 5 SuperDock is certified for use with Apple M series Macs; Thunderbolt 3 Intel Macs; Thunderbolt 5 and most Thunderbolt 4 Windows computers; Thunderbolt 5 and 4 Chromebook computers; and M series iPad Pro. See Tech Specs for current computer and OS compatibility information.
