ASUS Laptop AC Adapter tips:
1.Before ordering this replacement 65W 19V 3.42A Smart Power Cord/Charger PU500CA-XO016P Ultrabook ASUS Pro Advanced ADP-65WH AB ac adapter, you MUST check your laptop's input voltage and your original ac adapter's output voltage. Laptops with 18V~20V input voltage can use our ac adapter which has 19V output voltage; Laptops with 15V~17V input voltage can use our ac adapter which has 16V output voltage; Remember : never exceed ±1V tolerance. Using wrong output voltage adatper will damage your laptop computer.
2.You can calculate your original 65W 19V 3.42A Smart Power Cord/Charger PU500CA-XO016P Ultrabook ASUS Pro Advanced ADP-65WH AB ac adapter's output Wattage [W] by multiplying the Ouput Voltage [V] by output current [Amps]. You can choose a replacement ac adapter which has higher Amps than your original ac adapter's, but you can not choose an ac adapter which has lower Amps than your original ac adapter's because it can not provide sufficient power to your laptop. Adapters with higher Amps will not damage your laptop computer. The adapter's output current (Amps) and output power (watts) are maximum load ratings. Computers only draw as many amperes or watts as they need.
