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.
