Compact USB-C to Square Plug Adapter

This adapter converts a USB-C Power Delivery charger into a square-tip DC connector for compatible Lenovo ThinkPad laptops. It supports PD profiles up to 100W and handles voltages of 18V to 20V. The aluminium alloy housing measures 3.4cm by 2.7cm by 1cm for easy transport.

Fits Between PD Charger and Legacy Laptop Port

The male USB-C end plugs into any PD-capable wall charger or power bank supplying 40W, 60W, 90W or 100W. The female square-tip output connects directly to the laptop's proprietary DC jack, eliminating the need to carry the original bulky power brick. No extra cables or driver installation are required.

Sustained Output Through Aluminium Heat Sinking

The built-in intelligent PD chip negotiates the correct power contract and maintains it during continuous charging sessions. Aluminium alloy construction provides corrosion resistance and rapid heat dissipation to keep the adapter cool under full 100W load. It serves models including X1 Carbon generations 2 through 4, X1 Yoga first generation, T series from T431s to T470s, X series from X240 to X270, and E series E431 and E440.
