Compatible 135W replacement adapter

This 135W AC adapter replaces Lenovo 135W and 90W chargers for ThinkPad P1 2nd Gen models including 20QT and 20QT000VCA. It delivers 20V at 6.75A through a slim plug tip designed for the specified laptops. The unit does not replace 170W or 230W adapters required by higher-power configurations.

Thermal and power behaviour

The adapter carries UL listed cords and built-in overload, short-circuit, over-voltage, over-current and over-temperature protections. A durable sealed case resists water and humidity while maintaining high power efficiency during normal charging. Two six-foot cords give a combined reach without needing extension leads.

Build integration notes

The package includes a UL listed three-prong AC cord and a matching DC cord, both six feet long, so the power brick can sit on the floor or desk while the wall plug stays distant. Buyers whose ThinkPad requires a 170W or 230W supply cannot use this model and must source a higher-wattage unit.

Questions about this item

How do I connect the 135 W adapter to my ThinkPad P1 2nd Gen, and what mistake should I avoid?

Plug the slim tip firmly into the laptop's DC jack until it clicks; the common error is leaving a small gap that prevents charging.

Which parts of the 135 W adapter may need replacement after extended use?

The 6 ft AC cord, 6 ft DC cord, and the slim tip can wear from bending; the internal brick is sealed and not user-serviceable.

What power limit appears first when the 135 W adapter runs continuously at full load?

The 135 W output ceiling is reached before the 170 W or 230 W thresholds, so sustained peaks above 135 W will trip overload protection.
