45W AC Adapter for Lenovo

The ProXtend AC045WSQ is a 45 W AC adapter for Lenovo ThinkPad notebooks. It converts AC input to DC output and connects through a Square USB, also called Slim Tip, connector. This provides external power for compatible notebooks with that connection.

Its fixed output is 20 V at 2.25 A and cannot be adjusted. The input accepts 100–240 V AC at 50/60 Hz, so it can be used with different mains input ranges when the notebook’s requirements match.

For indoor use, the adapter lists protection against overvoltage, overcurrent, overtemperature, overload and short circuit. Its stated efficiency is 88–89%.

Package contents: the specified cable with an EU plug, 0.8 m long.
