170W replacement adapter for ThinkPad P1

This 170W AC adapter replaces the original Lenovo 135W and 170W units for ThinkPad P1 models including 20Y3003JUS through 20Y30046US. It delivers 20V at 8.5A for compatible mobile workstations. The adapter does not replace 230W or 300W chargers, so buyers needing higher wattage should look elsewhere.

Installation and common issues

The package includes a 6 ft UL listed 3-prong AC cord and a 6 ft DC cord for extended reach without extra cables. Installation is a direct plug-in replacement for the original adapter. The ruggedized case resists moisture and humidity, while internal safety features filter voltage spikes and limit output to protect the laptop. Ensure the tip matches the P1 charging port before use.

Deciding specification: 170W output

The single specification that determines fit is the 170W maximum output at 20VDC 8.5A. This matches the original 135W and 170W Lenovo adapters for the listed ThinkPad P1 models. It will not support systems that require 230W or 300W input. Verify your laptop's required wattage on the original charger label before purchasing.
