For safety reasons, it is recommended to use a Voltage Converter / Transformer that's max watts is at least 50% higher than your appliance. For example, if your appliance is rated at 1000 watts, you need to buy a Transformer with a max power of at least 1500 watts or greater. Some appliances, such as heating appliances, power tools, motors, laser printers and TVs need a bigger "buffer zone" because they tend to spike in power, For safe operation it is advisable to choose a voltage converter that is twice the actual wattage rating of these appliances.
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.
Volts (AC input) x Amps(amperage) = Watts (Wattage)
110V x 0.5A = 55W
