Friendly Note:

• We recommend you purchase a transformer that is 100% higher than 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 100% slack for the transformer. Using them to maximum capacity will eventually burn the transformer out after prolonged use. 
• Some items, such as TV, laser printers, heater appliances, and power tools, will spike when you turn them on.
• For these situations, you need to buy a transformer that is at least 3 times the item's capacity.
