240 W AC Adapter for ASUS ROG Zephyrus

This 240 W AC adapter delivers 20 V at 12 A through a 6.0 x 3.7 mm DC connector. It replaces part number ADP-240EB B and supports worldwide input voltage from 100 to 240 V at 50 to 60 Hz. The unit is designed for compatible ASUS ROG Zephyrus and Strix laptops.

Suitable for owners of listed Zephyrus S15.

Buyers with laptops that require a different output voltage, amperage or DC pin size should look elsewhere. The adapter will not fit models using a smaller or larger barrel connector. It is also unsuitable for ultraportables that need a lower-wattage charger.

6.0 x 3.7 mm DC pin size

The 6.0 x 3.7 mm barrel connector is the single specification that determines physical compatibility. Verify this exact pin size on the original charger or laptop port before purchasing. An incorrect pin diameter will prevent a secure connection and power delivery.
