Your Peripherals and Power Your Computer with One Cable

Connect your Thunderbolt devices, monitor(s), USB peripherals, powered speakers, and Ethernet cable to the dock and then link them all to your computer with a single Thunderbolt cable. Got a laptop computer? You can keep its power adapter in your bag because Echo 20 Thunderbolt 4 SuperDock will power it with up to 100W of charging power. When it is time to leave, just unplug the Thunderbolt cable, grab your computer, and go.

Up to 100W of Charging Power

Featuring 2.5 Gigabit Ethernet, Echo 20 Thunderbolt 4 SuperDock 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, saving you the cost of another adapter. You can get great performance gains – 250 percent the speed of Gigabit Ethernet – without rewiring! Need to connect to a switch without 2.5Gb Ethernet support? The Sonnet dock also supports 1Gb/s and 100Mb/s link speeds.

Downstream Thunderbolt Ports – Simple Comprehensive Connectivity for Work and Play

Echo 20 Thunderbolt 4 SuperDock features three Thunderbolt 4 ports: one for connection/power to your computer – ideal for Mac and Windows laptop computers with only one or two Thunderbolt ports because you can connect and charge on the same port – plus two for connecting Thunderbolt peripheral devices.

The Thunderbolt peripheral ports also support USB4 and USB 3 peripherals, and even provide 15W power each to support the most demanding bus-powered Thunderbolt and USB peripherals. If your computer supports it, you can even connect another display.

Powerful

10Gbps USB-A and USB-C Ports

Echo 20 Thunderbolt 4 SuperDock features four USB 3.2 Gen 2 (10Gbps) Type A ports and four USB 3.2 Gen 2 Type-C ports – two each on the front and back – to support super-fast USB NVMe SSDs at up to full speed. And unlike some other docks,  Echo 20 doesn’t skimp on power either – each port provides up to 7.5W to ensure that drives with higher peak power requirements can mount and operate without fail. An added benefit for the USB-C ports is they support the Type-C Charging spec, enabling the dock to charge devices even when the computer is off, sleeping, or disconnected.

Each Port Provides Up to 7.5W
