Compatible Charger for Lenovo Workstations

This 170W AC adapter delivers 20V at 8.5A for Lenovo ThinkPad P53 20QN, Legion Y545 PG0 81T2 and Legion Y7000 2019 PG0 81T0 models. It accepts a universal 100-240V input at 50/60Hz for worldwide mains compatibility. The unit is supplied new with a black housing and a Square Yellow connector. Builders needing a different connector shape or higher wattage should look elsewhere.

Power Capacity and Protection Limits

The adapter provides a maximum output power of 170W, matching the original supply rating for the listed Lenovo laptops. Integrated safeguards include overvoltage, overtemperature, short-circuit and overcurrent protection circuits. It will not support systems that draw more than 170W or require a voltage other than 20V. Users with higher-power mobile workstations cannot use this unit.

Included Cable and Practical Effect

The package contains the AC adapter and a US power cord so the charger is ready for North American outlets. No additional cables, tips or software utilities are bundled. The Square Yellow connector fits the listed models directly without adapters. Owners of laptops with round or USB-C charging ports cannot use this supply.

Questions about this item

Will the 20V 8.5A output run a ThinkPad P53 that originally used a lower-wattage charger?

The adapter delivers 20V at 8.5A for 170W maximum output, matching the P53 20QN requirement; it will negotiate the correct voltage with the laptop's charging circuit.

How can I confirm the 170W adapter is operating correctly after connecting it?

The laptop should show charging status immediately, the adapter's LED (if present) will illuminate, and the system will report 20V input under power-management settings.

Does the package include both the 170W adapter and a US power cord, or must the cord be purchased separately?

The box contains one AC adapter and one US power cord, so no separate cable purchase is needed for standard wall outlets.
