45W AC Adapter for Asus Laptops

This DELL ADP190237U adapter delivers 19V at 2.37A for compatible Asus VivoBook and ZenBook models. It replaces a lost or damaged original charger rated at 45W or the lower 33W variant. The unit is new and UL listed for electrical safety.

Replaces 45W and 33W Asus chargers

If your current brick outputs 19V 1.75A or 19V 2.37A this unit restores full charging speed. The jump is worth it when the original cable frays, the connector loosens or the power brick fails completely. It also covers the 20V 11.8A specification noted in the data.

Check your model and connector size

Verify your laptop appears in the compatible series list such as VivoBook 14 X415 or ZenBook UX330 before ordering. Confirm the barrel plug measures 4.0 by 1.35mm and that your device expects a 19V input. The corded design uses a two-pin North American wall plug.

Questions about this item

What connector size does the ADP190237U use to fit my Asus laptop?

It uses a round 4.0*1.35 mm barrel connector that matches the charging port on the listed VivoBook and ZenBook models.

How do I install this charger and what step do people often miss?

Plug the AC cord into the brick, insert the barrel tip firmly until it seats, then connect to mains; the step often missed is pushing the tip in fully so the laptop registers 19 V 2.37 A.

When will the cord or brick need replacement?

Replace the unit if the cable sheath frays near the strain relief, the brick overheats, or output drops below 45 W; the UL-listed design includes auto-recovery protection to extend service life.
