170W 20V AC Adapter for ThinkPad P52

This 170 watt AC adapter delivers 20 volts at 8.5 amps for the Lenovo ThinkPad P52 series. It replaces the original Lenovo 135W and 170W units but does not replace the 230W or 300W chargers. Buyers who need a higher-wattage supply for larger workstations should look elsewhere.

Extra Long 6 ft Power Cord Installation

The package includes a UL-listed 3-prong AC cord measuring 6 ft and a DC output cord also measuring 6 ft for extended reach. Installation is straightforward: connect the AC cord to the adapter brick, plug into a 100-240V outlet, and attach the DC tip to the laptop. A common issue is selecting this 170W model when the system actually requires a 230W or 300W unit, which this adapter cannot substitute.

Sustained Load Behaviour with Safety Protections

The adapter maintains a steady 170W output under continuous demand thanks to high power efficiency and built-in safeguards. Overload, short-circuit, over-voltage, over-current and over-temperature protections engage automatically during prolonged heavy use. The durable case resists extreme conditions and seals out water and humidity to preserve consistent performance over long sessions.
