It replaces a lost or damaged original charger for these specific ultraportable series. Buyers with other Asus ranges or higher-wattage requirements cannot use this unit.

Output ratings and headroom

The adapter delivers 19V at 2.37A for a total of 45W through a 4.0mm by 1.35mm barrel connector. It accepts 100-240V 50/60Hz mains input worldwide. A laptop that draws more than 45W will not charge correctly with this supply.

Connector size

The DC plug measures 4.0mm outer diameter by 1.35mm inner diameter. This exact dimension decides whether the adapter physically fits the laptop’s power jack. Verify the port size on the target machine before ordering.

Questions about this item

Will this 19 V 2.37 A adapter power my older Asus Q302LA without issues?

Yes — it matches the 19 V 2.37 A 45 W requirement and the 4.0 mm × 1.35 mm connector used by the Q302 series.

How can I confirm the charger is delivering the rated 45 W after I plug it in?

The adapter is CE, ROHS and FCC certified; a USB-C power meter on the output will show 19 V at up to 2.37 A when the laptop draws full load.

Does the box include a detachable AC cord or only the foldable-plug brick?

The unit has a built-in foldable plug so no separate AC cord is needed; the 4.0 mm × 1.35 mm DC cable is permanently attached.
