Description

An ASUS 19 V 2.37 A laptop charger is a 45 W DC power adapter that supplies regulated power to compatible ASUS laptops and other devices. It takes standard AC input (100–240 V, 50–60 Hz) and outputs 19 volts DC at up to 2.37 amps, enough to power the laptop’s internals and charge its battery. The connector is a barrel-type plug with an outer diameter of 5.5 mm and inner diameter of 2.5 mm, which must match your device’s power port.
