20V 170W AC Adapter

The WAWEIS 20V 8.5A 170W adapter supplies regulated power to compatible Lenovo ThinkPad Y500 and Y500N laptops. It accepts worldwide input voltage from 100 to 240VAC at 50 or 60Hz.

Replaces 45N0111 45N0112

This adapter replaces Lenovo part numbers 45N0111 and 45N0112 as well as references 36200401 and 36200232. The jump is worth it when the original charger is lost, damaged or no longer holds a stable output. FCC, CE and RoHS certifications confirm compliance with international safety standards. The 10 foot cord adds reach compared to shorter factory cables.

Suits ThinkPad Y500 owners

Buyers needing a direct replacement for the listed ThinkPad models will find full OEM compatibility and 100 percent new components. The smart chip provides overheating protection while isolation materials reduce interference. Users with laptops requiring a different voltage, amperage or connector size should look at something else. The 12 month warranty period covers manufacturing defects.
