What it is and who it's for

This 65W AC adapter replaces the original charger for a wide range of Lenovo IdeaPad laptops. It delivers 20V at 3.25A through a 4.0×1.7mm barrel connector. The unit accepts 100-240V input for worldwide use and includes a three-prong power cord. It is built for owners of compatible IdeaPad 3, 5, Flex, S340, S145 and Chromebook models needing a direct replacement.

How it fits into a build

The adapter plugs into any standard mains outlet using the supplied three-prong cord. Its 100-240V 50-60Hz input removes the need for a separate travel converter. The single barrel tip connects directly to the laptop's charging port. No extra cables or docking hardware are required to restore power to the supported notebooks.

Capacity and headroom

Rated at 65W, the charger also covers devices that draw 20V at 2.25A (45W). It will power and charge the listed IdeaPad 3, 5, Flex and Chromebook models under normal workloads. Systems requiring higher wattage or a different connector size cannot use this adapter. The output is fixed at 20V 3.25A with no selectable voltage steps.
