Lenovo ThinkPad 65W AC Adapter (Slim Tip)

The Lenovo 4X20E75157 is a 65 watt AC adapter designed for ThinkPad notebooks that use the slim tip power connector. It plugs into a standard 120 volt wall outlet and delivers steady power to run the laptop while also charging the battery. Because it meets energy-efficiency standards and has a compact body, it can stay on a desk all day or travel easily in a backpack or briefcase.

This adapter ships with a three-prong plug that matches US outlets, making it a straightforward replacement for a lost or worn original charger. Many users keep a second unit at the office, in a classroom, or in a shared meeting space so they can leave the primary adapter at home and lighten their daily carry. Remote workers who move between a home office and a coworking site will appreciate having reliable power available at both locations.

The slim tip connector mates securely with compatible ThinkPad models, reducing the risk of accidental disconnection. Whether you need to top off the battery during a presentation, run demanding software throughout the day, or keep a spare charger in your travel bag for conferences, the 4X20E75157 offers a practical solution without adding unnecessary bulk.
