Critical Voltage And Current Match

The adapter delivers 20 V at 8.5 A for a total of 170 W output. Input accepts 100 to 240 V at 50 to 60 Hz for worldwide use. The DC plug and voltage must match the laptop's requirements exactly or the system will not charge. Using a lower wattage unit can limit performance or prevent charging under load.

Sustained Load Behaviour And Safety

Built-in overload short-circuit over-voltage over-current and over-temperature protections engage during continuous high-draw operation. The durable sealed case resists humidity while maintaining stable output. A 6 ft AC cord and 6 ft DC cord provide flexible placement without daisy-chaining extensions that could increase resistance.

It supplies up to 170 watts at 20 volts and 8.5 amps, matching the original Lenovo 170W charger so the laptop can run and charge at full speed.

The adapter uses a 20V output — what does that cap in practice?

The 20V DC output is fixed for the ThinkPad P52 barrel connector; the unit will not negotiate higher voltages and is limited to 8.5A maximum current.

What physical connection does this adapter need to fit the ThinkPad P52?

It uses the standard Lenovo rectangular 20V barrel tip and includes a 6 ft DC cord plus a 6 ft 3-prong AC cord for wall connection.
