Questions about this item

What input voltage range does the adapter accept, and how does that limit where it can be used?

It accepts 100-240 VAC at 50/60 Hz, so it works on mains supplies worldwide without a voltage converter.

What connector does the adapter use to fit the Vivobook 15 X540 series, and what cable length is included?

The tip matches the original Asus barrel connector for the X540 family, and the total power cord length is 10 ft.

How is the adapter installed, and what common mistake should be avoided?

Plug the AC cord into the brick, connect the barrel tip to the laptop, then insert the mains plug; do not force the tip if the polarity marking does not line up.
