65W AC Adapter for Lenovo Z-Series

This new power supply replaces the original charger for Lenovo Z40, Z50 and Z70 laptops and several related sub-models. It delivers up to 65 watts at 20 volts and 3.25 amps, and also covers the lower 45-watt requirement of 20 volts 2.25 amps. The unit accepts a universal input range from 100 to 240 volts. A UL-listed power cord is included in the box.

Output Rating Determines Compatibility

The adapter provides a maximum output of 20V 3.25A for 65W and is backward compatible with the 20V 2.25A 45W specification used on some models in the same series. Buyers must confirm that their laptop requires a 20-volt barrel connector rated at or below 65 watts. Devices that need a different voltage, a higher wattage or a USB-C power input cannot use this adapter.

Simple Plug-In Installation

Installation consists of connecting the IEC power cord to the brick and inserting the barrel tip into the laptop's charging port. The cord and adapter both carry UL listing, confirming they meet the required safety standards. The only common issue is ordering the wrong tip polarity or voltage for a model outside the listed Z-series range, so verifying the laptop's exact power label before purchase avoids returns.
