240W ASUS AC Adapter for ROG Laptops

This 240-watt power supply delivers 20 volts at 12 amps to compatible ASUS Republic of Gamers notebooks. It accepts 100 to 240-volt input at 50 to 60 hertz for worldwide use. The unit uses a 6.0 by 3.7 millimetre barrel connector with a central pin. It is supplied new in black.

Replaces Lost or Damaged 240W Units

The adapter matches the output of original ADP-240EB B, ADP-240BB B, ADP-200JB D and ADP-230GB B chargers. It restores full charging speed for listed Zephyrus, Strix and ZenBook Pro models. The jump is worth it when the original brick fails or a spare is needed for travel. Buyers needing higher wattage for larger workstations cannot use this unit.

Limited to 6.0 mm Barrel Connector

The fixed 6.0 by 3.7 millimetre tip with centre pin fits only laptops designed for that specific jack. It cannot charge devices that require USB-C Power Delivery or a different barrel size. Input voltage auto-ranges from 100 to 240 volts, so no manual switching is required. Polarity and pin layout are fixed by the connector geometry.
