65 W AC adapter for IdeaPad and Essential laptops

This 65 W power supply delivers 20 V at 3.25 A through a 5.5 × 2.5 mm barrel connector. It accepts 100–240 V AC input at 50–60 Hz, making it suitable for worldwide mains voltages. The unit replaces multiple original part numbers including ADP-65KH B, 36001646 and 45N0215.

Bundled AC power cable completes the connection

The package includes one AC adapter and one detachable mains cable, so the charger is ready to use without sourcing a separate lead. The cable plugs into the adapter’s IEC inlet and a standard wall socket. No additional software or drivers are required for operation.

Verify connector size and model compatibility first

Check that the laptop’s charging port matches the 5.5 mm outer and 2.5 mm inner diameter before ordering. Confirm the exact model appears in the supported lists for IdeaPad U, Z, V, P, N series and Essential B, G, V, Z, P series with integrated graphics. The adapter is not suited for devices needing a different voltage, wattage or connector geometry.

Questions about this item

Does the 5.5×2.5 mm connector tip wear out and need replacing?

The barrel connector is a fixed part of the cable; if the tip becomes loose or damaged the whole adapter must be replaced.

What limits continuous output at 20 V 3.25 A?

The 65 W rating is the maximum sustained power; the adapter will shut down if the load tries to draw more current.

How hot does the brick get when it runs at 65 W all day?

The unit is convection-cooled and will become warm to the touch, which is normal for a 65 W supply in a sealed enclosure.
