65W 19V Adapter for Asus Zenbook and X Series

This 65-watt AC adapter delivers 19 volts at 3.42 amps through a 4.0 by 1.35 millimetre barrel connector. It powers compatible Asus Zenbook UX305, UX21A and UX32A models as well as X Series laptops such as the X540 and X553 families. The unit accepts 100 to 240 volt input at 50 or 60 hertz for worldwide use.

Replaces Lost or Damaged 65W Barrel Chargers

It serves as a direct replacement when the original 65-watt brick is lost, damaged or no longer holds a secure connection. The jump is worth it when the existing adapter shows frayed cables, intermittent charging or a loose barrel tip that requires careful positioning. Buyers needing a higher wattage unit for docking stations or discrete graphics configurations cannot use this model.

Limited to 19V 3.42A Barrel Connector Devices

The fixed 19 volt output and proprietary 4.0 by 1.35 millimetre tip restrict use to laptops that specify exactly this voltage, current and connector geometry. It cannot charge USB-C devices, nor can it power systems requiring 20 volts or higher current ratings. Polarity and tip dimensions must match the device label before connection.

Questions about this item

What connector size does the 65W adapter use for the Asus Zenbook UX305?

The adapter uses a 4.0 x 1.35 mm DC connector that matches the Zenbook UX305 charging port.

How do I connect the adapter to mains power, and what step is often missed?

Plug the supplied power cord into the adapter's IEC inlet first, then into a 100-240V 50/60Hz wall socket; skipping the cord-to-adapter connection leaves the unit dead.

When should the power cord be replaced on this 65W unit?

Replace the cord if the plug pins are bent, the insulation is cracked, or the cord becomes warm during normal 19V 3.42A operation.
