65W 19V AC Adapter for Asus VivoBook

This 65W AC adapter supplies 19V at 3.42A for compatible Asus VivoBook, Flip and Transformer Book models. It replaces original part numbers including ADP-65DW B and PA-1650-01. The unit ships with a detachable mains cord and the 5.5mm by 2.5mm barrel connector.

Input range limits worldwide use

The adapter accepts AC 100-240V at 1.8A across 50-60Hz, so it works on most mains supplies without a voltage switch. Output is fixed at 19V 3.42A 65W; devices that require a different voltage or higher current cannot use this unit. The barrel connector size is fixed at 5.5mm by 2.5mm.

Straightforward swap with correct tip

Installation is a direct swap: unplug the old charger, connect the supplied mains cord, and insert the 5.5mm by 2.5mm plug into the laptop. The main risk is using the adapter on a model that needs a different connector diameter or a higher wattage rating. Safety certifications include UL, CE, FCC and RoHS.

Questions about this item

Should I choose the 65W model or a lower-wattage adapter for my Asus VivoBook X551?

The 65W 19V 3.42A output matches the original ADP-65DW B specification, so it fully supports the X551 series without limiting performance.

What does the 19V 3.42A rating mean when the adapter is connected to my laptop?

It delivers a steady 19 volts at up to 3.42 amps, providing the 65 watts the VivoBook X551 and X751MA require for charging and full-speed operation.

Does the 5.5mm x 2.5mm barrel connector fit the charging port on an Asus X551MA?

Yes, the 5.5mm*2.5mm centre-positive plug is the exact size used across the listed X551, X751MA and VivoBook models.
