Well, in the United States, we often refer to products by the most popular brand instead of what they\u2019re actually called. For example, kleenex and band-aids are used to refer to facial tissues and adhesive bandages. Similar to those, Variac is the brand name of one of the original variable autotransformers or adjustable voltage transformers. &nbsp;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you\u2019re looking for an adjustable voltage transformer or a Variac, how do you know which one to get?
