Lenovo USB-C Dual Display Travel Dock

The Lenovo 40B90000US is a USB-C dual display travel dock that turns a laptop into a full workstation wherever work takes you. It can drive two external monitors at 3840 x 2160 resolution and 60 Hz, so spreadsheets, creative projects, or live demos appear sharp and fluid whether you connect through HDMI 2.1 or DisplayPort 1.4.

Beyond the display outputs, the dock supplies the ports most travelers need. Two USB-C 3.2 Gen 2 and one USB-A 3.2 Gen 2 let you attach storage devices, a webcam, or other peripherals at high speed, while the RJ45 Gigabit Ethernet port offers a stable wired network connection in hotels, conference rooms, or offices with spotty Wi-Fi. A single USB-C cable carries data, video, and up to 65 W of power delivery, so your laptop stays charged without juggling extra adapters.

The housing weighs only 4.8 ounces and measures 4.7 × 2.2 × 0.8 inches, which means it slips into a laptop sleeve or backpack pocket without adding bulk. Consultants moving between client sites, hybrid employees who switch desks often, and students who need reliable connectivity in classrooms will appreciate how quickly this dock sets up and packs away. It works with Windows 10 and Windows 11, and it requires no complex installation—just plug in and start working.
