Compatibility & Fit
USB-C Charging Devices Only
This adapter charges through USB-C. It is not for older Lenovo laptops with a rectangular slim-tip or round barrel power jack — for slim-tip laptops choose a slim-tip adapter of the right wattage (for example 4X20E50566 or 4X20Q88547 at 135 W).
Wattage Matters
65 W suits most USB-C ultraportables and mainstream business laptops that ship with a 45 W or 65 W USB-C adapter. Laptops supplied with a higher-wattage adapter (for example 100 W or more) may charge more slowly or not under heavy load.
Singapore Socket
The UK-pin plug fits Singapore's standard 3-pin (Type G) wall sockets directly. Use Lenovo SmartFind to confirm compatibility with your exact model.
