WAWEIS 19V 2.37A 45W laptop AC adapter

Replacement 19 V 45 W adapter

This WAWEIS AC adapter supplies 19 V at 2.37 A for a total of 45 W, matching the original charger for the Asus Q503UA-BSI5T17 2-in-1 15.6" touch-screen laptop. It accepts worldwide input voltage from 100 to 240 VAC at 50 or 60 Hz. The unit includes a 10 ft power cord and carries FCC, CE and RoHS certification. Built-in protections cover over-current, over-voltage, short-circuit and total power events.

For Asus Q503UA owners needing a spare

The adapter is a direct replacement for the Asus Q503UA-BSI5T17 model, so buyers with that exact laptop will find full compatibility. It is not suitable for laptops that require a different voltage, a higher wattage or a proprietary connector not used by this Asus model. Users who need a USB-C power delivery charger or a multi-voltage travel adapter should look at other products.

45 W output with 10 ft reach

The 45 W rating comfortably powers the Asus Q503UA-BSI5T17 during normal use and charging, while the 10 ft cord gives generous placement flexibility. Headroom ends at the rated 45 W; systems drawing more current or requiring 19 V at higher amperage will exceed this adapter's capacity. The fixed 19 V output also means it cannot serve devices that need variable voltage profiles.
