45W 19V AC adapter for select Asus laptops

This 45 watt power supply delivers 19 volts at 2.37 amps through a 4.0 by 1.35 millimetre barrel connector. It replaces lower-rated 33 watt units and supports a wide range of Asus ultraportable and mainstream models listed by the supplier. The unit ships new with a detachable AC mains cable included.

100-240V input suits global mains voltages

The adapter accepts alternating current from 100 to 240 volts at 50 or 60 hertz, so it works on household supplies worldwide without a separate voltage converter. Built-in protection guards against overcurrent, overvoltage, overload, overtemperature and short-circuit conditions. CE, FCC and RoHS certifications confirm compliance with common safety and environmental standards.

4.0mm tip size decides fit

The barrel plug measures 4.0 millimetres outer diameter by 1.35 millimetres inner diameter; only laptops that require this exact tip will connect securely. Buyers whose devices use a different connector diameter or pin layout cannot use this adapter. Verify the required tip dimensions on the original charger or the laptop's specification sheet before purchasing.
