65W 20V 3.25A replacement adapter

The Kenuco 65W AC adapter delivers 20V at 3.25A through a 4.0x1.7mm barrel connector. It accepts 100-240V input at 50/60Hz for worldwide use. The unit is compatible with numerous Lenovo IdeaPad and Chromebook models listed by the supplier. Condition is new.

Replaces 45W or 65W 20V units

This adapter substitutes an original 45W 20V 2.25A or 65W 20V 3.25A supply for the supported IdeaPad 1, 3, 5, Flex 4, 5, 6, V14, V15, V17, 110, 320, 330, 520, 710S, L340, S145, S340, S540 and Chromebook N22, N23, N42 series. The upgrade is worthwhile when the original charger is lost, damaged or no longer holds a stable output. Buyers who need a different voltage, a higher wattage or a USB-C connector cannot use this model.

Fits 4.0x1.7mm barrel jack laptops

The 4.0x1.7mm plug mates directly with the DC-in port on the compatible laptops above. The 100-240V input works on any mains supply without a voltage selector. No extra cables or converters are required beyond the supplied power cord. Builders who need a slimmer tip, a right-angle plug or a detachable USB-C cable should look elsewhere.

Questions about this item

What connector size does the 65W adapter use for the IdeaPad 1, 3 and 5 series?

The charger terminates in a 4.0 x 1.7 mm barrel plug that matches the listed IdeaPad 1, 3 and 5 models.

How is the adapter connected to mains power and what step is often missed?

Plug the supplied AC cord into the brick, then into a 100-240V 50/60 Hz socket; the step users miss is fully seating the barrel plug into the laptop before switching on the wall outlet.

When should the 65W power supply be replaced?

Replace the unit if the output drops below 20V 3.25A, the connector becomes loose, the cable shows exposed conductors or the brick overheats during normal charging.
