Asus uses several connector standards across its range, and the same model name can ship with different parts depending on the region. Below is the full picture: what is in stock right now, which series each unit fits, and the three checks that decide whether a replacement will work.

Three checks before you order a Asus replacement

  1. Match the voltage exactly. The label on your original adapter reads something like "Output: 19.5V 3.34A". The replacement must carry the same voltage – a higher or lower figure risks no charge or a protection fault.
  2. Amperage may be equal or higher. The laptop pulls only the current it needs, so a 4.62A adapter safely replaces a 3.34A one, never the other way round.
  3. Confirm the connector. Barrel size (outer x inner diameter in mm), USB-C, or a proprietary magnetic / special tip. Measure before ordering if the listing does not state it.

Frequently asked questions

Are these original Asus adapters?
They are third-party replacements built to Asus electrical specifications, not OEM parts.

My Asus needs 19V 3.42A - can I use a higher amperage?
Yes. Equal or higher amperage is safe; the laptop only draws what it needs. Voltage must stay identical.

My laptop has a USB-C port - can I charge through it?
Only if the port supports Power Delivery. Check the original specification before relying on it as a replacement.
