Here are our best selling travel voltage converters and plug adapter kits. These are small and light in weight compared to larger voltage transformers. Travel voltage converters are not designed for continuous use and must be unplugged when not in use. The sizes range from small 50W to 300W voltage transformers and 1600W - 1875W solid state voltage converters. Do not use travel voltage converters for power tools, large electronics or appliances, hair straighteners or coffee makers.
