The manufacturer recommends you purchase a transformer that is 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. 

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 , TV , fridge , Hair curlers, irons, thermal equipment power tools spike when you turn them on. For these types of situations you need to buy a transformer that is at least 4 times the items capacity
