How to find correct Voltage Converter?
To determine the right voltage converter for your appliance, first find out the voltage (110 or 220 Volt AC) and wattage rating (watts or amps) information on the back or bottom of the appliance or from instruction book of an appliance. If no watts are shown and only amps are shown, multiply the volts (input AC) by the amps to find the watts. For example, Volts(AC input) x Amps(amperage) = Watts (Wattage) 110V x 0.
