90W Replacement Adapter for Asus Laptops

This iTekiro AC adapter delivers up to 90 watts at 19 volts to compatible Asus models including the M1603, M1605, P500, PU301, PU401, PU450, PU500, PU550 and Q524 series. It serves as a direct replacement for original 45W, 65W and 90W chargers, powering the laptop and charging the battery whether the system is on or off.

4.5 mm Center-Pin Connector and Voltage Limits

The adapter uses a 4.5 mm barrel plug with a centre pin that must match the laptop's charging port exactly. It accepts AC input from 100 to 240 volts at 50 to 60 Hz for worldwide use, but it does not replace 120W or 150W chargers, so laptops requiring higher wattage are not supported.

Upgrade from Lower-Wattage or Damaged Chargers

This unit replaces worn, lost or lower-capacity 45W and 65W Asus adapters, providing the full 90W headroom for consistent performance. The ruggedised case resists moisture and humidity, while the included six-foot AC cord and six-foot DC cord eliminate the need for extension leads in most setups.
