This article covers Kensington LD4650P デュアルビデオ USB-C ドッキングステーション K-Fob™スマートロック付き.

Overview

The Kensington LD4650P is a unique 2-in-1 solution that combines a USB-C docking station with the K-Fob smart lock system. It allows you to secure your laptop physically while expanding its connectivity with dual DisplayPort video outputs, USB-A ports, gigabit Ethernet, and 60W Power Delivery 3.0 charging. Designed for Windows PCs (including Surface Laptop 3 and Surface Book 1/2), this dock targets professionals who need both peripheral expansion and theft deterrence in one device. At the heart of the LD4650P is the K-Fob mechanism: a cable tether loops around a fixed object, and the lock arm engages when the laptop is placed. Only an authorized K-Fob (two included) can release the lock, making it ideal for open-plan offices, co-working spaces, or any environment where leaving a laptop unattended is risky. The dock supports single display up to 2560×1440 at 60Hz or dual displays at 1920×1080 at 60Hz, covering most productivity setups.

Product Info

The Kensington LD4650P (model K38400NA) was launched around 2020 as a mid-range security-focused docking station. It occupies a niche where physical laptop locking and docking converge — few competitors offer both in one package. The package includes the dock, two K-Fobs, a cable tether, an AC adapter, and a quick-start guide. Warranty is Kensington’s standard 3 years (verify regionally). Priced around ¥17,380 on Japan, it represents good value for users who prioritize security alongside everyday desktop expansion. Market position: this is not just a USB-C hub; it’s a security appliance. It directly addresses the pain point of laptop theft in shared workspaces without requiring a separate lock and dock. For organizations that issue corporate laptops, the LD4650P streamlines deployment with integrated security.

Best Use Cases

  • IT administrators and security officers: Deploy a single device that reduces the risk of laptop theft while giving employees the docking functionality they need. The K-Fob lock integrates with existing physical security policies and can be managed via replaceable fobs. - Remote/hybrid workers: Set up a permanent docking station at your home office or assigned desk. Connect your laptop to instantly power it, drive two monitors, access wired networking, and use USB peripherals — all while physically locking the laptop to the desk. Peace of mind during breaks or video calls. - Co-working space users: In shared environments where laptops are frequently left unattended, the LD4650P adds a layer of physical deterrence. The lock mechanism is unobtrusive but effective, and the cable tether can be secured to any sturdy object. This product is not suitable for Mac users, those needing dual 4K output, or anyone who wants a portable, lock-free dock. The integrated lock adds bulk and weight, so it’s best suited for fixed-desk scenarios.
