How to calculate the wattage of your notebook
To see if the universal charger is suitable for your netbook or notebook, you can calculate the wattage of your notebook. First, check your current charger or check the properties of your notebook. Then multiply the volts by the amperage to calculate the total watts needed. For example, if your current charger has an output of 15V (voltage) and 3A (amperage), you need an adapter with 45 watts (15V x 3A = 45Watt) at minimum
