Volts AC. On consumer electronics (and similar) equipment, specifies the RMS alternating current voltage rating. 110VAC is standard in North America, 220VAC or 250VAC in most of Europe and the rest of the world (Britain, Australia and maybe similar places seem to have 240VAC, but this may be more due to the vagaries of reporting inexact quantities than to any real difference in standards); some places are as weird as having 160VAC.
