170W AC Adapter for ThinkPad P52

This 170W AC adapter is built for Lenovo ThinkPad P52 models including 20M90010US through 20M90016US and 20M9001YUS. It delivers 20V at 8.5A to match the original charger specifications. Mobile professionals who need a reliable replacement power source for daily work will find it suitable. It does not support systems that require a 230W power supply.

Installation and common issues

The package includes a 6 ft UL listed 3-prong AC power cord and a 6 ft DC power cord for flexible desk placement. Connection is a direct plug into the laptop's charging port with no drivers required. A frequent mistake is attempting to use this 170W unit on a ThinkPad configured for a 230W adapter, which will not provide sufficient power. Verify the original charger wattage before ordering.

Sustained load behaviour

The adapter accepts a worldwide input range of 100 to 240V at 50 to 60Hz for stable operation across regions. Built-in overload, short circuit, over voltage, over current and over temperature protections maintain safe output during extended charging sessions. The durable case resists extreme conditions and seals out water and humidity. High power efficiency ensures a steady 170W supply without thermal throttling under continuous use.
