170W AC Adapter for ThinkPad P-Series

This 170W AC adapter delivers 20V at 8.5A through a slim-tip 3-pin connector. It replaces the original Lenovo charger for ThinkPad P50 through P73, W540, W541 and T540P mobile workstations. The unit accepts 100-240V input at 50-60Hz for worldwide use. It is not suitable for laptops that require more than 170W or charge solely via USB-C.

Slim-Tip Connector and Build Quality

The adapter uses the rectangular slim-tip plug found on 170W ThinkPad power supplies, ensuring a secure fit on supported models. A 100-240V auto-switching input eliminates the need for a voltage selector when travelling. The supplier states compliance with U.S. safety standards and a strict manufacturing process for extended service life. A high-quality power cable is included in the package.

Upgrade From 135W Units

This 170W unit can power ThinkPad models that ship with 135W adapters, including X1 Extreme, Yoga 9i and select IdeaPad Gaming laptops, as well as 135W ThinkPad docking stations. The higher wattage provides headroom for demanding workloads without changing the connector. Buyers whose laptops demand over 170W or use USB-C charging should not purchase this adapter.
