Compatible AC Adapter for ThinkPad X140e

This AC adapter replaces the original power supply for Lenovo ThinkPad X140e models 20BL0014US and 20DU0003US. It delivers a steady 20V output from a worldwide 100-240VAC input at 50 or 60Hz. The unit ships with the mains power cord included and is supplied new. It is intended for owners of those specific ThinkPad models who need a direct replacement.

Simple Plug-In Replacement

Installation requires no tools or software: connect the mains cord, plug the barrel connector into the laptop, and power on. Built-in over-voltage, short-circuit and over-current protections guard against common electrical faults. The adapter is not suitable for ThinkPad models that require a different output voltage or connector type, so buyers with other series should verify compatibility before ordering.

Steady Output Under Continuous Use

The adapter maintains its rated 20V output during extended charging sessions and while the laptop runs demanding workloads. Protective circuits engage automatically if voltage, current or a short-circuit condition exceeds safe limits, preventing damage to the power brick or the notebook. It is not designed for hardware that draws more current than the original X140e supply provides.
