Replacement AC Adapter for ThinkPad P51

This 170W AC adapter is designed for Lenovo ThinkPad P51 mobile workstations. It matches the original voltage and current ratings for direct replacement. The unit suits professionals who need a reliable spare or travel charger for supported models.

Durable Case with 6 ft Cords

The adapter housing resists water and humidity for everyday transport. A UL-listed 3-prong AC cord and a DC cord each measure 6 ft, giving flexible desk placement. Built-in protections guard against overload, short circuit, over-voltage, over-current and over-temperature events.

20V 8.5A Output Decides Compatibility

Output is fixed at 20V and 8.5A for 170W total power. The adapter replaces Lenovo 135W and 170W units but cannot supply the 230W or 300W required by higher-spec ThinkPad configurations. Buyers needing those higher wattages must select a different charger.
