Questions about this item

Does the 4.0mm x 1.2mm barrel plug fit my Asus UX305?

Yes, the 4.0mm x 1.2mm connector matches the charging port on the listed Asus UX305 models and all other compatible devices in the specification.

How do I install the adapter, and what step is often missed?

Plug the IEC C7 mains lead into the adapter, connect the barrel tip to the laptop, then plug the lead into a 100-240V 50/60Hz wall socket; the step often missed is ensuring the mains lead is fully seated in the adapter before switching on.

When will the adapter or its cable need replacement?

Replace the unit if the barrel tip becomes loose, the cable shows exposed conductors, or the adapter no longer delivers a steady 19V 2.37A output under load.
