Compatible 170W adapter for ThinkPad P51

This 170W AC adapter delivers 20V at 8.5A for Lenovo ThinkPad P51 models including 20HH002PUS, 20HH002QUS, 20HH003AUS, 20HH003BUS, 20HH003CUS, 20HH003DUS, 20HH003EUS and 20HH003FUS. It suits owners who need a replacement or spare charger for daily work and travel. The unit is new and includes a 6 ft AC cord plus a 6 ft DC cord.

Replaces original 135W and 170W chargers

The adapter replaces the original 135W and 170W chargers supplied with the listed P51 systems. It does not replace the 230W charger, so buyers who need 230W output should look elsewhere. The jump from a 135W unit is worth it when the laptop draws more power under heavy load or when the original 170W brick has failed.

Limited to 170W output over barrel connector

The barrel connector and 20V 8.5A rating cap delivery at 170W, so the adapter cannot support systems that require 230W. Input accepts 100 to 240V at 50 to 60Hz for worldwide use. Output options listed at 180W max with 19.5V 9.23A or 19V 9.5A are not usable for the P51 models above, which need the 20V 8.5A setting.

Questions about this item

What length of power cord does the 170W adapter include?

The package supplies a 6 ft UL-listed 3-prong AC cord and a 6 ft DC cord, giving a combined reach of about 12 ft from wall outlet to laptop.

How do I connect the adapter to the ThinkPad P51 correctly?

Plug the 3-prong AC cord into the adapter brick, then into a 100-240V outlet; insert the DC barrel plug firmly into the P51 power jack until it seats — partial insertion is the common mistake that prevents charging.

When should I replace the AC power cord on this charger?

Replace the 6 ft AC cord if the insulation cracks, the plug prongs bend, or the cord becomes intermittent; the DC cord should be swapped if the barrel connector loosens or the cable frays near the strain relief.
