Docking Station Lenovo ThinkPad USB 4 Smart Dock 5500 with 100W AC adapter

The Lenovo ThinkPad USB 4 Smart Dock 5500 with 100W AC adapter is a USB-C/USB4 docking station designed to expand connectivity for compatible laptops. It provides a single-cable connection to power, external displays, wired networks and multiple peripherals, streamlining workspace setup for office and home environments. Supplied with a 100W AC adapter, the dock supports power delivery while offering a variety of ports for displays, storage devices and input devices.

Advantages

The dock consolidates power delivery, video output and peripheral connectivity into one compact unit, reducing cable clutter and making laptop docking faster and more consistent. Included 100W AC adapter enables laptop charging and stable operation of connected devices. USB4 compatibility improves bandwidth and display support compared with legacy USB-C docks, while integrated Ethernet and multiple USB ports provide reliable wired networking and accessory connectivity.

Suitable for

• Office workstations requiring multiple monitors and wired Ethernet
• Home offices that need a single-cable docking solution for laptops
• Users who connect external storage, keyboards, mice and other peripherals
• Environments where stable power delivery and high bandwidth for displays are needed

When it may not be suitable

This dock is intended for laptops that support USB-C or USB4 host connections and power delivery; it may not provide full functionality if a laptop lacks USB4 or proper alternate-mode support for video output. If a workstation requires legacy ports such as VGA or serial interfaces, this dock may not meet those specific legacy-connector needs.

Key specifications

• Host interface: USB-C / USB4 compatible connection for docking and data/video transfer
• Power delivery: 100W AC adapter included for laptop charging and powering connected devices
• Display support: Multiple external display outputs via supported video modes over USB4 (dependent on host capabilities)
• Network: Integrated Gigabit Ethernet for wired LAN connectivity
• USB ports: Multiple USB ports for peripherals and external storage (high-speed data transfer)
• Form factor: Compact desktop dock designed for integration into office or home workstation setups

How to use

Connect the dock to a compatible laptop using the USB-C/USB4 host cable. Plug the included 100W AC adapter into the dock and a power outlet to enable power delivery and charge the laptop. Attach external monitors to the dock’s display outputs and connect peripherals such as USB storage, keyboards and mice to the available USB ports. Use the integrated Ethernet port for a wired network connection. Confirm display and power settings on the laptop to ensure the host supports the desired multi-monitor and charging configuration.

What to consider before purchase

• Verify that your laptop supports USB4 or the required USB-C alternate modes for video output and power delivery.
• Check the maximum external display configuration and resolutions supported by your laptop when using a single-cable dock.
• Confirm that included power output (100W) is sufficient to charge your laptop under typical workload conditions.
• Ensure the available port types on the dock match the peripherals and monitor inputs you plan to use.

Usage recommendations

For consistent multi-monitor setups, connect displays directly to the dock and configure display settings in the operating system. Use the included 100W adapter to maintain battery charge during heavy workloads and avoid relying solely on the laptop’s internal ports when docked to reduce wear on the laptop’s connectors.
