19V 120W adapter for ASUS ZenBook Pro

This 19V 6.32A 120W AC adapter delivers 120 watts through a 4.5mm by 3.0mm barrel connector with a centre pin. It accepts 100 to 240V input at 50 to 60Hz and ships with a three-prong US power cord. The unit weighs .5kg and carries a six-month warranty.

Fits listed ASUS models only

Owners of the specific ZenBook Pro, N550, N750 and ROG models named in the compatibility list can use this charger. Buyers whose laptops require a different connector size such as 5.5mm by 2.5mm or a different voltage and current rating cannot use this adapter.

4.5mm x 3.0mm connector with centre pin

The barrel plug measures 4.5mm outer diameter by 3.0mm inner diameter and includes a small centre needle. This single physical specification determines whether the adapter will mate with the laptop’s DC-in jack.

Questions about this item

Does the box contain the AC adapter and a power cord, or must the cord be purchased separately?

The package includes one AC adapter and one power cord fitted for your country.

How do I know whether the 4.5 mm by 3.0 mm connector matches my Asus laptop?

Check your original charger tip; this adapter uses a 4.5 mm outer and 3.0 mm inner diameter with a centre pin, not the 5.5 mm by 2.5 mm size used on some models.

Will the 120 W rating actually deliver full power to a ZenBook Pro UX550 under load?

Yes, the unit outputs 19 V at 6.32 A for 120 W continuous power, matching the laptop's requirement.
