AC Adapter for ASUS Laptops

This 19V 3.42A AC adapter replaces the SADP-65NB AB unit for compatible ASUS notebooks. It delivers 65W of continuous power through a 5.5mm by 2.5mm barrel connector. The unit is supplied new and includes a 12-month warranty with a 60-day free replacement or refund option.

Steady 65W Output Under Load

The adapter maintains its rated 19V 3.42A output during extended charging sessions rather than only in brief bursts. This steady delivery supports consistent battery recharging and system operation while the laptop is in use. OEM-compatible design ensures the electrical characteristics match the original supply specifications.

5.5mm by 2.5mm Barrel Connector

The single specification that determines fit is the 5.5mm outer diameter and 2.5mm inner diameter barrel plug. If your ASUS laptop requires a different connector size or pin arrangement, this adapter will not connect. Buyers who need a different tip size or a USB-C power input should look for an alternative model.

Questions about this item

How much heat or noise does the 19 V 3.42 A adapter produce when running continuously?

The 65 W unit has no fan, so it runs silently; warmth is normal for a 19 V 3.42 A brick under full load.

Which laptop-side connector must my ASUS already have for this 5.5 mm 2.5 mm tip to fit?

Your ASUS needs a 5.5 mm outer and 2.5 mm inner barrel jack — the exact dimensions on the SADP-65NB AB replacement.

Will the 65 W output work safely with an older ASUS that shipped with a lower-wattage charger?

Yes — the laptop draws only what it needs, so the 19 V 3.42 A supply is compatible with earlier models requiring less power.
