The Watson VCG-SD50 converts 220 VAC foreign electricity to 110 VAC for continuous use with electronic products designed for the USA. This two prong device for non-grounded connectors, is for devices with a maximum wattage of 50 watts.
Note! Voltage converters do not convert electric cycles (60 Hz American vs. 50 Hz foreign). Some US appliances may operate somewhat slower when used overseas.
