45W AC Adapter for ASUS Laptops

This 45-watt AC adapter supplies 19 volts at 2.37 amps from a 100-240 volt input. It ships with three interchangeable tips measuring 5.5 by 2.5 millimetres, 4.0 by 1.35 millimetres and 4.5 by 3.0 millimetres. The unit is designed to replace the original charger for a wide range of ASUS notebooks.

Suitable for owners of listed Vivobook.

Buyers whose ASUS laptop appears in the extensive compatibility list can use this adapter as a direct replacement. Users with devices that require a different output voltage, a higher wattage rating or a connector size not included in the three tips should look for an alternative power supply.

Steady 45-watt output under continuous load

The adapter maintains its rated 45-watt delivery during extended charging sessions without stepping down to a lower burst figure. Thermal protection engages only if internal temperatures exceed safe limits, allowing uninterrupted operation for typical office or study workloads.
