An AC cable and power adapter are included, along with a UK power plug. The charger is designed for indoor laptop use and carries RoHS compliance certification.

Check compatibility before ordering

  • Confirm your full Lenovo model number matches a compatible model.
  • Check that your laptop requires 65W and an output of 18–20V at 3.25A.
  • Confirm the charger’s connector suits your laptop.
  • Check that you have an indoor mains socket available.
