The Echo 11 dock has four Thunderbolt 4 ports, three USB 3.2 Gen 2 (10Gbps) Type A ports, one USB 2.0 Type A charging port, one RJ45 Gigabit Ethernet port, one 3.5 mm combo audio port, and one SD 4.0 card slot. The dock is compatible with all computers equipped with Thunderbolt 4 ports, M1 Mac computers with Thunderbolt/USB ports, Intel Mac computers with Thunderbolt 3 ports, and more recent Windows computers with Thunderbolt 3 ports.

All Thunderbolt docking stations act as central hubs for indirect attachment of peripherals such as storage devices, input devices and headphones to a computer that typically often lacks the required number of ports in its own chassis. Thunderbolt 4 Dock then overcomes this limitation on number of ports on a computer by enabling the connection of up to 16 devices at once, including up to two monitors, as well as charging the computer with up to 90 watts of power, supporting wired network connectivity, and providing the ability to read SD memory cards. With its mix of three 10 Gbps USB Type A ports and three 40Gbps Thunderbolt 4 (USB-C) peripheral ports, the company claims the Echo dock connects almost all relevant current and legacy devices, while supporting high-performance peripherals.
