The Watson VCG-SD85 converts 220 VAC foreign electricity to 110 VAC for continuous use with electronic products designed for the USA. This three prong converter works with both grounded and non-grounded connectors, and is for use with devices with a maximum wattage of 85 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.
