Compatible 135 W AC adapter for ThinkPad P1 20QT

This 20 V 6.75 A adapter delivers 135 W to Lenovo ThinkPad P1 models 20QT and 20TH. It includes a UL-listed 6 ft AC cord and a 6 ft DC cord for extended reach. The slim plug tip fits the supported P1 variants without an adapter.

Check your ThinkPad model

Verify that the laptop is a ThinkPad P1 with a 20QT or 20TH part number such as 20QT0084US or 20TH0009US. Confirm the original charger is rated 135 W or 90 W; this unit does not replace 170 W or 230 W adapters. Ensure the connector matches the slim tip shown in the product images.

Replaces 135 W and 90 W Lenovo chargers

It substitutes the factory 135 W or 90 W power supply for the listed ThinkPad P1 units. The upgrade is worthwhile when the original adapter is lost, damaged or no longer holds a charge. It is not suitable for ThinkPad models that require 170 W or 230 W input.

Questions about this item

Does the box include both the AC and DC cables or just the adapter brick?

The package supplies a UL listed 6 ft. 3-prong AC power cord and a 6 ft. DC power cord so no separate cables are required.

My ThinkPad P1 shipped with a 90W brick — will this 135W unit work safely?

Yes, it replaces both the 90W and 135W Lenovo chargers listed for the 20QT and 20TH series; it does not replace 170W or 230W models.

What does the 20V 6.75A rating mean for daily charging?

It delivers the full 135W the P1 20QT and 20TH models expect, so the battery charges at the same speed as the original Lenovo supply.
