Power adapter for select ASUS laptops

This 45 W AC adapter delivers 19 V at 2.37 A and accepts a 100-240 V input at 50-60 Hz. It is built for ASUS Vivobook, Zenbook, Taichi and Transformer Book models that require a 4.0 mm by 1.35 mm barrel connector. The package includes the adapter and a detachable power cord.

Connector compatibility limits use

The 4.0 mm by 1.35 mm tip fits the listed ASUS series but will not mate with the smaller 3.0 mm by 1.0 mm connector used on certain other Zenbook models. Buyers who need that narrower tip cannot use this unit. No other output voltages or plug sizes are provided.

4.0 mm by 1.35 mm barrel decides fit

The single specification that determines whether this adapter works is the centre-positive 4.0 mm outer diameter and 1.35 mm inner diameter plug. Verify the laptop’s original charger or service manual shows this exact connector before ordering.

Questions about this item

Which connector size matches my ASUS model?

This adapter uses a 4.0mm by 1.35mm tip. The listing shows a photo to distinguish it from the 3.0mm by 1.0mm tip used on UX31, UX31E, UX21, UX21K and UX21E models.

What does the 45W rating mean when the adapter is plugged in?

The unit delivers up to 19V at 2.37A, giving a maximum of 45W to the laptop. The actual draw depends on what the laptop requests at that moment.

What input voltage range does the 100-240V spec cover in practice?

The adapter accepts AC input from 100V to 240V at 50Hz or 60Hz, drawing between 0.6A and 1.8A depending on the mains voltage.
