Thunderbolt Dock

The Sonnet Echo 20 Thunderbolt 4 SuperDock utilizes Thunderbolt 4 to provide multiple ports and expansion options to your compatible computer with a single cable. Gain access to a variety of connections, such as Thunderbolt 4, USB 3.2 Gen 2, 2.5 GbE RJ45 LAN, 3.5mm audio jacks, and more. The HDMI 2.1 port allows you to connect an 8K @ 60 Hz display directly to the dock without the need for an adapter. There are also storage expansion options, such as the M.2 NVMe SSD slot and a SD 4.0 card reader.

HDMI 2.1, Thunderbolt 4, and USB 3.2 Gen 2

The built-in HDMI 2.1 port on the Echo 20 allows you to plug in an external display up to 8K @ 60 Hz directly. An HDMI adapter is not required to achieve max resolution. The Echo 20 also features three Thunderbolt 4 ports, one for connecting to your host device and the other two for directly connecting Thunderbolt peripherals and accessories. The two Thunderbolt 4 ports support USB4 and USB 3.2 devices and even provides up to 15W of power. Also available are four USB-A 3.2 Gen 2 and four USB-C 3.2 Gen 2 ports.

2.5 Gb Ethernet

Featuring 2.5 Gigabit Ethernet, the Echo 20 supports a 2.5 Gb/s link speed over common Cat 5e (or better) cabling when used with a compatible Ethernet switch or NAS with 2.5Gb Ethernet support. This saves you the trouble of having to invest in an Ethernet adapter. Need to connect to a switch without 2.5Gb Ethernet support? The Sonnet dock can also supports 1 Gb/s and 100 Mb/s link speeds.

M.2 SSD Slot

The built-in M.2 NVMe SSD slot enables you to add up to 8TB of SSD storage (sold separately) to your system without having to connect a storage device to your Echo 20 or upgrading your computer. Installing the SSD is easy and straightforward. Simply remove the two screws securing a bottom panel cover, insert the SSD, and reinstall the bottom cover with the two screws. Transfer and access data at up to 800 MB/s, and effortlessly store large files, media libraries, or your Time Machine backups.

    Customs, duties & taxes

    There are no customs duties or taxes on orders shipping within the EU. Orders shipped outside of the EU may be subject to import taxes, customs duties and fees collected by the destination country. The recipient of an international shipment may be subject to such import taxes, customs duties and fees, which are collected once a shipment reaches the recipient's country. Additional charges for customs clearance must be paid for by the recipient; we have no control over these charges and cannot predict what they may be. Customs policies vary widely from country to country; and when customs clearance procedures are required, it can cause delays beyond our original delivery estimates. We advise that you contact your local customs office for more information.
