The manufacture recommends you purchase a transformer that is 50 to 100% higher then the wattage you need.
You should know that you will never damage your appliance with a higher wattage transformer, however if you buy one that is not powerful enough, it will not work.
Use Amps to calculate watts
Volts (times) Amps = Watts, For Example 110V x 5A = 550W
Remember to leave at least a 100% slack for the transformer. Using them to maximum capacity will eventually burn the transformer out after prolonged use. Some items, such as, laser printers and power tools spike when you turn them on. For these types of situations you need to buy a transformer that is at least 3 times the items capacity.
