The Impact VC-SU50 50 Watt Step-Up International Voltage Transformer converts 110 VAC USA electricity to 220 VAC for continuous use with electronic products designed for Europe. This is for devices with a maximum wattage of 50 watts. This is a two prong device for non-grounded connectors.
Note! Voltage converters do not convert electric cycles (60 Hz American vs. 50 Hz foreign). Some overseas appliances may operate somewhat faster when used in the U.S.
