65W AC adapter for Lenovo IdeaPad

This 65 watt AC adapter supplies 20 volts at 3.25 amps and is backwards compatible with 45 watt models requiring 20 volts at 2.25 amps. It accepts a universal 100 to 240 volt input at 50 to 60 hertz for worldwide use. The barrel connector measures 4.0 by 1.7 millimetres and suits a wide range of IdeaPad, Yoga and Flex laptops.

Check connector and voltage before ordering

Confirm that your laptop uses a 4.0 by 1.7 millimetre barrel tip and requires 20 volts output. Verify the original adapter part number against the listed replacements such as ADP-45DW BA, ADL45WCC or Lenovo part numbers 5A10H42919 through 5A10H43632. This unit is not for devices needing a different tip size, a USB-C connection or a voltage other than 20 volts.

Thermals noise and power draw in normal use

The adapter runs on standard mains input and delivers up to 65 watts to the laptop. No fan is present so operation is silent. Heat output scales with the load drawn by the notebook; under typical charging loads the housing remains warm but within normal limits for a sealed power brick.

Questions about this item

Does the package include a mains cable or only the adapter and the 4.0×1.7 mm tip?

The adapter has a fixed 4.0×1.7 mm output connector and a built-in AC plug for 100-240 V mains; no separate mains cable is required.

Should I choose this 65 W unit or a 45 W model for an IdeaPad 330-15IKB?

This unit delivers 20 V 3.25 A (65 W) and also covers 20 V 2.25 A (45 W) loads, so it works for both power ratings.

Will the 65 W rating actually reach the laptop, or is it limited by the 4.0×1.7 mm barrel?

The barrel is rated for the full 20 V 3.25 A output, so the laptop can draw the full 65 W when needed.
