Verify Your ThinkPad Model and Original Wattage

Confirm that your ThinkPad P51 shipped with a 135W or 170W charger before ordering because this adapter does not replace a 230W unit. Check the input range of AC 100-240V at 50-60Hz matches your local mains supply. The output options include 20V 8.5A among other voltages so ensure your laptop accepts this profile.
