Replacement 170W AC Adapter for ThinkPad P1

This 170 watt AC adapter replaces the original Lenovo 135W and 170W chargers for ThinkPad P1 models including 20Y30034US through 20Y3003HUS. It delivers 20V at 8.5A to power the laptop and charge the battery whether the system is on or off. The unit accepts worldwide input from 100 to 240V at 50 to 60Hz.

Extra Long Cord Set and Safety Features

The package includes a 6 foot UL listed 3-prong AC power cord plus a 6 foot DC power cord, giving extended reach without extension cords. Internal safety circuitry filters input voltage spikes and limits output voltage and current to protect the laptop from electrical hazards. A ruggedised case resists moisture and high humidity for mobile durability.

170W Maximum Output Decides Compatibility

The adapter provides 170W maximum output, so it is not a substitute for Lenovo 230W or 300W chargers required by higher-power configurations. Buyers whose ThinkPad P1 shipped with a 230W or 300W unit need a higher-wattage replacement instead. The 6.18 by 3.31 by 1.97 inch brick weighs 26.50 ounces with cords attached.

Questions about this item

Will the 6 ft DC cable or the 170 W brick need replacement first under daily use?

The 6 ft DC cable and 3-prong AC cord are the moving parts; the ruggedised brick is sealed against moisture and humidity, so the cables typically wear before the adapter itself.

What stops the 20 V 8.5 A output from climbing higher during a long rendering session?

Internal protection circuits limit output voltage and current to the rated 170 W, filtering input spikes so the adapter cannot exceed its 20 V 8.5 A specification.

How hot or loud does the 26.5 oz brick get when it runs at 170 W all day?

The sealed, fanless case relies on passive convection; it warms to a safe operating temperature but produces no audible noise during continuous 170 W load.
