This 19V 3.42A AC adapter delivers 65W of power through a 5.5x2.5mm barrel connector. It accepts a 100-240V 1.8A 50/60Hz input and includes a three-prong AC inlet with a 48-inch power cord. The unit is designed as a direct replacement for listed Asus part numbers.

Asus Laptop Compatibility

This adapter fits a wide range of Asus notebooks including Vivobook S, X, Q, R, K, A, F, D, U, X401, X501, X502, X550, X551, X552, X555, X751, and K500 series models. It matches numerous OEM part numbers such as ADP-65DW, ADP-65HB, PA-1650-66, and AD887320. Buyers with laptops requiring a different voltage, amperage, or connector size should look elsewhere.

5.5x2.5mm Connector Size

The 5.5x2.5mm centre-positive barrel plug is the single specification that determines fit. Verify the laptop’s DC jack dimensions and polarity against this connector before purchase. An incorrect connector size will prevent the adapter from seating or delivering power.

Can I use this 65 W adapter on an Asus notebook that originally shipped with a 45 W unit such as the ADP-45BW?

Yes, the higher 65 W rating is safe; the laptop draws only the current it needs while the voltage and 5.5×2.5 mm connector match.

How do I verify the adapter is delivering 19 V 3.42 A after I plug it in?

The laptop charging LED should illuminate and the battery icon in Windows must show "Plugged in, charging" with no voltage warning.
