Its compact footprint and EU plug specification simplify use across European mains outlets without additional adapters.

Suitable for

• Charging Lenovo ThinkPad laptops with Thunderbolt 3 power input that accept higher-wattage adapters
• Powering laptops during heavy multitasking, video editing, software development, and other high-demand workflows
• Use with Thunderbolt 3 docking stations to supply power and expand connectivity
• Travel and office use where a compact EU-plug charger is required

Key specifications

• Output power: 135 W
• Connector type: Thunderbolt 3 (USB-C compatible form factor)
• Input voltage: compatible with standard European mains (EU plug)
• Functionality: charging and power delivery for compatible laptops; supports use with Thunderbolt 3 docks
• Physical design: compact adapter with integrated EU plug for portability

How to use

Connect the charger to an EU mains outlet, then insert the Thunderbolt 3 plug into the laptop’s corresponding port. Confirm that the laptop recognizes external power and that charging indicators are active. When used with a Thunderbolt 3 docking station, connect the charger to the dock if the dock requires external power and then attach the laptop to the dock via Thunderbolt 3. Avoid forcing the connector; align it and insert gently. Disconnect power by removing the plug from the laptop first, then from the mains.

Recommendations

Use the charger with compatible Lenovo ThinkPad models and Thunderbolt 3 ports only. Operate within normal indoor temperature and humidity ranges, avoid covering the adapter during heavy use to ensure ventilation, and regularly inspect the cable and connectors for damage. If the laptop supports lower-wattage charging profiles, the adapter will negotiate appropriate power delivery; for sustained high-performance workloads, confirm your laptop model accepts a 135W adapter.
