Seven Star st Step Up/Down transformer converts 220-240 volts down to 110-120 Volts or 110-120 volts up to 220-240 volts. 1000 WATTS

seven star st 1000 Step Up/Down transformer converts 220-240 volts down to 110-120 Volts or 110-120 volts up to 220-240 volts. 1000 WATTS 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 0.5A = 55W The size of a voltage converter is defined by the wattage. Therefore, the size you'll need depends on which devices you'll be powering and the number of watts they use. We would recommend using a voltage converter / transformer which has a Wattage that is 2 to 3 times higher than your appliance. Certain appliances such as power tools, motors, laser printers and TVs require a converter 2-3 times the Watts that the ...
