170W AC Adapter for ThinkPad P50 and P51

This 170W AC adapter replaces the original Lenovo 135W and 170W chargers for ThinkPad P50 and P51 models. It delivers 20V at 8.5A to power the laptop and charge the battery whether the system is on or off. The unit is not compatible with 230W or 300W Lenovo chargers.

Thermals, noise and power draw

The adapter accepts worldwide AC input from 100 to 240V at 50 to 60Hz and provides a maximum output of 170W. High power efficiency ensures consistent and continuous power delivery during normal use. Internal safety features filter voltage spikes and limit output to protect the laptop from electrical hazards.

Decisive specification — 170W output limit

The single specification that decides fit is the 170W maximum output; it replaces 135W and 170W Lenovo units but cannot replace 230W or 300W chargers. Buyers needing higher wattage for other ThinkPad models must choose a different adapter. The ruggedised case withstands harsh mobile environments and seals against moisture and humidity.

Questions about this item

How do I connect the 6 ft 3-prong AC cord and 6 ft DC cord without strain?

Plug the 3-prong cord into a 100-240 V outlet, connect the DC barrel to the ThinkPad P50 or P51, and route both cords so the 6.18" x 3.31" x 1.97" brick rests on a flat surface — tension on the barrel plug is the common mistake.

Which parts will need replacement after extended use?

The 3-prong AC cord and DC cable are the wear items; the sealed 26.50 oz adapter case is moisture-resistant and has no user-serviceable parts inside.

At what load does the 170 W limit appear during continuous operation?

The adapter delivers 20 V at 8.5 A for a 170 W maximum; sustained draw at or above that level triggers the internal protection and shuts output down.
