120W AC Adapter Charger for Asus ROG and VivoBook - Reliable High

In this review the NASAP 120W AC Adapter Charger is examined as a practical replacement for a range of Asus notebooks, and the bottom line is straightforward: it is a no-nonsense, high-power option for users who need a dependable external power supply. The reviewer found it best suited to owners of gaming and large-screen Asus models that require a 19V, 6.32A supply. Its biggest selling point is the full 120W output combined with the common 5.5mm x 2.5mm barrel connector, which makes it a direct fit for many ROG, Zenbook and VivoBook variants that do not use the smaller 4.5mm x 3.0mm interface.

Key Features

• 120W output: Provides enough power to run demanding laptops and charge the internal battery while under load, making it suitable for gaming and heavy multitasking.
• Compatible voltage and current: Delivers 19V at 6.32A (listed as compatible with 19V 6.3A), matching the requirements of many Asus models to avoid underpower situations.
• Common barrel connector: Uses a 5.5mm outer by 2.5mm inner DC plug so it will fit the large roster of Asus laptops that require that interface size.
• Safety protections: Built-in safeguards against short circuit, overvoltage, overcurrent and overheating aim to keep the laptop and adapter protected during extended use.
• Includes 3-prong cord and 5ft cable: The package comes with a three-prong AC cord and a 5ft cable for convenient placement and reach from wall outlets.

Who It's For

This adapter is ideal for owners of older and current Asus ROG GL5xx/GL7xx series laptops, many N and G series machines, and select VivoBook and Zenbook models that specify a 19V, 6.32A or similar power brick with a 5.5mm x 2.5mm plug. Gamers and power users who need a replacement or spare adapter to sustain high-performance workloads will appreciate the full 120W rating.

Users who should look elsewhere include owners of Asus laptops that require the smaller 4.5mm x 3.0mm connector, machines with proprietary barrel or pin connectors, or those who need a USB-C PD charger; this model is not compatible with those interfaces.
