  Compatibility Tips

• Check Your Connector Size – ASUS uses both 4.0mm x 1.35mm (small barrel) and 5.5mm x 2.5mm (standard barrel) tips.

• Avoid Underpowering – Using a 65W charger on a laptop that requires 90W may result in slow charging or performance issues.

• Universal Input Voltage – Ideal for travel; these chargers support 100–240V input with a proper plug adapter.
