Replacement power adapter

This 170W AC adapter supplies 20V at 8.5A for compatible Lenovo ThinkPad P53 and Legion models. It accepts 100-240V input at 50/60Hz for worldwide use. The unit includes a US power cord and a square yellow connector tip. It is intended for owners who need a direct replacement charger.

Square yellow connector and protections

The square yellow tip matches the charging port on the listed ThinkPad and Legion laptops. A US plug is fitted to the detachable power cord for North American outlets. Built-in overvoltage, overtemperature, short-circuit and overcurrent protections guard the adapter and the connected device. The black housing is designed for daily transport in a laptop bag.

Thermal and power behaviour

At full load the adapter delivers its rated 170W output through the 20V rail. Internal protection circuits shut the unit down if temperature or current exceed safe limits. Normal operation runs within the 100-240V input range without external switching. No fan is present so acoustic output is limited to faint coil noise under heavy load.

Questions about this item

What output does the 20V 8.5A 170W AC adapter deliver and what does that cap in practice?

It delivers a fixed 20V at up to 8.5A for a maximum of 170W, capping the power any connected Lenovo laptop can draw from this unit.

What connector size and shape does this adapter use to fit the laptop?

It uses a square yellow tip that matches the charging port on compatible Lenovo ThinkPad and Legion models.

How is the adapter installed and what step do people often get wrong?

Plug the US power cord into the brick, then insert the square yellow tip firmly until it seats; the common mistake is leaving the tip partially inserted so charging does not start.
