What this charger delivers

This 65-watt AC adapter supplies 19 volts at 3.42 amps through a round barrel connector. It is built for Asus Vivobook models that draw 65 watts or less, including 45-watt and 33-watt variants. The unit carries UL listing and uses fire-retardant materials with a foldable plug for travel.

Who it suits and who it does not

Buyers with a compatible Vivobook, Zenbook, or Experbook that uses one of the four listed barrel sizes can use this as a direct replacement. It will not work for laptops that charge through USB-C or require 90 watts and above, and the long exclusion list names dozens of specific Asus models that use different connector types or higher power inputs.

Capacity and headroom

The adapter comfortably powers any supported laptop rated up to 65 watts, delivering stable current for charging and operation. It runs out of headroom for gaming-class or workstation Asus models rated at 90, 120, or 180 watts, which demand more current than this brick can supply.

Questions about this item

Does this charger need a separate mains lead or is the plug built in?

The unit has a foldable plug that folds flat for travel, so no separate mains lead is required.

Will it safely run an older 45 W or 33 W Vivobook that uses a round connector?

Yes, the 19 V 3.42 A output works with 65 W, 45 W and 33 W models that accept a round connector.

How can I confirm the charger is delivering power once I connect it?

A charging indicator on the adapter lights up when it is supplying power to the laptop.
