Designed exclusively for Surface, Kensington proudly presents the powerful MD125U4 USB4 Portable Docking Station-an innovative mobile dock that offers all the power of USB4 to provide Dual 4K support, up to 40Gbps upstream speed, and up to 100W power pass-through. Power pass-through eliminates the need to travel with an additional power brick by using the Surface's USB-C power supply to power the dock while charging your device. Pairs with USB-C based Surface devices, and is compatible with Thunderbolt 3, Thunderbolt 4, and USB-C 3.2 devices running Window 10 or above. Two HDMI 2.1 ports deliver up to 8K @ 30Hz for a single monitor, and up to 4K @ 120Hz for dual monitors. Includes two HDMI ports, one USB-C port, two USB-A ports, and a 2.5Gbps Ethernet port. Cable storage clips neatly stow the 9.8" (25cm) USB4 cable during transport and when not in use. Includes Kensington three-year limited warranty.
