90W USB-C adapter for ASUS ROG

This 90-watt USB-C power supply delivers 20 volts at 4.5 amps for compatible ASUS ROG laptops. It also negotiates 5, 9 and 15 volts at up to 3 amps for other USB Power Delivery devices. The unit ships with a detachable mains cord and accepts 100 to 240 volt input at 50 to 60 hertz. CE certification is included.

Replaces lost or damaged ADP-90RE B units

The adapter matches the original ADP-90RE B part number and restores full charging speed when the factory brick fails or goes missing. It is not suitable for laptops that require more than 90 watts or a different voltage profile. Buyers who need higher wattage or a barrel connector should look elsewhere.

Plug-and-play with interchangeable mains cords

Installation is limited to selecting the correct regional cord and connecting the USB-C plug to the laptop. The only common issue is attempting to charge a device that draws more than 90 watts, which will cause the adapter to limit output or shut down. No driver or firmware action is required.
