*Efficiency FactorUse this factor to calculate the correct wattage transformer needed for your items. Multiply the WATT rating on your product with this factor and purchase transformer of at least that size. Example: If your blender requires 350W, then multiply 350 x 2.5 (efficiency factor of ST) = 875W. Thus, ST-1000 is recommended for this particular blender. To use multiple products, simply add watt rating of each product and multiply the combined watt rating with the efficiency factor. Always purchase a larger size transformer than your appliances required wattage to handle any power surges during operation. Feel free to contact or call us if you have any questions. Read our voltage converter guide or  tips and hints when using voltage converters.
