45W AC Adapter for Asus Laptops

This 45W AC adapter supplies 19V at 2.37A through a round connector. It is designed as a replacement charger for compatible Asus Vivobook, Zenbook and Chromebook models. The unit carries UL safety certification and operates on 100-240V input for worldwide use. It is a new accessory intended for laptops requiring 45W or 33W power.

Who this suits and who should look elsewhere

Buyers with listed Asus models needing a 45W round-connector charger will find a direct fit. It is not for laptops requiring more than 45W, nor for devices using 4.5mm by 3.0mm barrel plugs or USB-C power inputs. Users with higher-wattage Asus notebooks or different connector types must select another adapter.

Deciding specification: 19V 2.37A round connector

The critical detail is the 19V 2.37A output delivered via a round connector. This exact voltage, current and plug shape must match the original charger specifications on the laptop label. If the laptop demands a different voltage, amperage or connector format, this adapter will not work.
