Voltage Transformer Purchasing Guide: Prior to purchasing a voltage transformer, in order to avoid users frustrations and unnecessary returns, it is imperative to check and verify your appliances Maximum Power Consumption (MPC), which could be located on the devices nameplate or included in its user instruction. The appliances MPC must be less than this transformers Maximum Load Capacity (MLC), or it will NOT work. For safety concerns and optimal results, the manufacturer recommends that the transformers MLC should be equal or greater than your appliances MPC multiplied by 1.5. For example, if you have an appliance rated at 100 watts, you will need to choose a transformer with a maximum power of 150 watts or greater. Heating appliances, laser printers and power tools spike when you turn them On. For these products you need to buy a Voltage Converter Transformer that is at least 3 to 4 times the rated wattage.
