Power delivery scope

This 65W USB-C AC adapter delivers up to 65 watts at 20 volts and 3.25 amps, making it suitable for Asus laptops rated at 45W or 65W. It accepts a universal 100-240V input range for worldwide use. The unit is not designed for devices that require higher wattage such as 85W or 96W power bricks. Buyers whose machines demand more than 65W must select a different adapter.

USB-C charging limits

The adapter uses a single USB Type-C tip and a 7.5ft cord to supply power. It cannot charge laptops that rely on barrel connectors or proprietary tips. Output is fixed at 20V 3.25A; there is no adjustable voltage or current negotiation beyond the standard USB-PD profile implied by the fixed rating. Systems that require multiple simultaneous USB-C ports or higher Power Delivery profiles will not be fully supported.

Deciding specification

The critical figure is the 65W maximum output at 20V 3.25A, which matches Asus ZenBook, Vivobook, ExpertBook and Chromebook models listed in the compatibility data. If your laptop’s original charger is rated at 45W or 65W with a USB-C connector, this unit is a direct replacement. If the original rating exceeds 65W, this adapter will not provide sufficient power.

Questions about this item

Which power rating should I pick between the 45 W and 65 W versions?

The adapter delivers up to 65 W at 20 V 3.25 A and also works with 45 W laptops, so the single 65 W unit covers both needs.

It supplies the full 20 V 3.25 A the Zenbook expects, charging the battery at the same speed as the original charger while you work.

It provides a fixed 20 V 3.25 A over USB-C with 100-240 V input, matching the Asus models listed without additional negotiation.
