Kensington SD4839P USB-C docking station
The Kensington SD4839P is a nine-in-one USB-C dock built for Windows 10 and later laptops that support DisplayPort Alt Mode and Power Delivery. It delivers driverless operation, 85 W charging and up to 10 Gbps data throughput without installing extra software.
Thermals noise and power
The dock draws up to 85 W for host charging and runs passively with no fan, so it adds no audible noise to the desk. Power consumption scales with connected peripherals and the attached laptop’s charging state.
Mounting security and DockWorks
A zero-footprint mounting bracket and security cable lock slots let the unit sit flush on a surface or attach to a VESA mount, saving desk space and deterring theft. Free DockWorks software adds firmware updates and port management from a single dashboard.

Questions about this item
How do I install the Kensington K33480NA docking station and what step do people often miss?
Connect the dock to a USB-C port on a Windows 10 or later laptop that supports DisplayPort Alt Mode and Power Delivery 3.0. The step often missed is confirming the laptop USB-C port provides both video and 85W charging; a data-only port will not drive the three displays or power the notebook.
What maintenance or replacement will the Kensington K33480NA need later?
The dock is driverless and has no user-serviceable parts, so no routine maintenance is required. Keep the USB-C cable and the two DisplayPort++ 1.4 plus one HDMI 2.0 cables in good condition; replace any cable that shows wear or fails to negotiate 10Gbps data or 4K video.
What limit appears first when the Kensington K33480NA runs under sustained load?
The 85W Power Delivery 3.0 budget is the first ceiling; if the connected notebook and bus-powered peripherals draw more than 85W combined, the dock will throttle charging or drop ports to stay within the limit.
