Kensington SD5700T Thunderbolt 4 Dock (2021)

An 11-port Thunderbolt 4 dock that connects to a laptop over a single TB4 cable and delivers 90W of charging back to it. Beyond the host port, three downstream Thunderbolt 4 ports (15W each) can chain displays and storage, supporting either a single 8K@30Hz or dual 4K@60Hz setup. Wired networking is Gigabit Ethernet, and a UHS-II SD reader runs at up to 320 MB/s. Four USB-A ports — three at 10 Gb/s, one at USB 2.0 — and a 3.5mm combo jack complete the layout.

11-port Thunderbolt 4 dock with 90W laptop charging, three downstream TB4 ports, Gigabit Ethernet, UHS-II SD reader, and four USB-A ports.
