120W AC Adapter 19V 6.32A

This 120W AC adapter delivers 19V at 6.32A through a 5.5mm by 2.5mm barrel connector. It accepts 100V to 240V input at 50 or 60Hz with a 2.0A draw. The unit includes a US cable plug and has passed UL safety testing. It replaces Asus part numbers such as A15-120P1A and PA-1121-28.

For Asus ROG and VivoBook owners needing a direct

Buyers with compatible Asus models including ROG GL551, GL552, GL752, GL753, GL771, N550, N56J, Q550, X550 and X750 series can use this adapter. It matches the original voltage, current and connector size. Users whose laptops require a different voltage, a higher wattage or a different connector diameter should look elsewhere.

Simple plug-in installation

Installation consists of connecting the AC cable to the adapter, plugging into a mains socket and inserting the barrel tip into the laptop power jack. The most common issue is a connector size mismatch; the 5.5mm outer and 2.5mm inner diameters must match the laptop port exactly. Confirm the tip dimensions before ordering to avoid fitment problems.

Questions about this item

Your laptop needs a barrel jack with a 5.5mm outer diameter and a 2.5mm inner pin for the adapter to connect securely.

Will this 120W unit charge an older ASUS model that originally used a 150W brick?

It supplies 19V at 6.32A for 120W total; if the older machine requires more power it may charge slowly or not at all under load.

How can I confirm the adapter is delivering the rated 19V 6.32A after I plug it in?
