120W AC Adapter for Asus ZenBook

This 120W AC adapter delivers 20V at 6.0A through a 4.5 mm centre-pin connector. It fits Asus UX501, UX534, UX550 and UX563 series laptops that originally shipped with a 120W or 90W charger. Buyers needing a 150W, 180W or 230W unit cannot use this model.

Sustained Output Behaviour

The adapter maintains its rated 120W continuously thanks to built-in overload, short-circuit, over-voltage, over-current and over-temperature protections. A sealed case resists water and humidity while high power efficiency keeps internal temperatures stable during long charging sessions. The 6 ft DC cord allows flexible placement without voltage drop.

Connector and Power Limits

The 4.5 mm pin tip is the only interface; it will not mate with barrels that lack the centre pin or that require a different diameter. The brick replaces 120W and 90W originals but cannot supply the higher current demanded by 150W, 180W or 230W systems. The UL-listed 6 ft AC cord meets standard household outlet requirements.

Questions about this item

Does the 120 W adapter run hot or draw more power when used all day?

The unit delivers 20 V at 6.0 A for 120 W output and includes overload, over-voltage, over-current and over-temperature protection to keep heat and power draw stable during continuous use.

What must I already own to use this charger with my Asus laptop?

You need an Asus model that accepts a 4.5 mm barrel plug with a centre pin — compatible series include UX501, UX534, UX550 and UX563 — and a standard earthed wall socket for the UL-listed 3-prong AC cord.

Will this 120 W adapter work alongside the original 90 W brick I kept as a spare?

Yes, it replaces the original 90 W and 120 W chargers for the listed models, but it does not replace 150 W, 180 W or 230 W units, so the older 90 W brick remains usable on the same laptops.
