Sonnet’s Echo 11 Thunderbolt 3 Dock connects your peripherals to your computer through a single cable. Simply plug in your devices—such as a printer, keyboard, mouse, cable modem, hard drive, optical drive, USB license dongle, headphones or powered speakers, phone, tablet, and (up to) two 4K displays—to the dock with their supplied cables, and then connect your computer with the included Thunderbolt 3 (40Gbps) cable. The Echo 11 dock even charges compatible computers(5)  through the same cable. When it’s time to take your computer and go, just unplug the Thunderbolt cable to disconnect from everything at once!
