The Hisense 3-in-1 Stand Fan (HSF-40) operates on a standard voltage range of 220V to 240V at a frequency of 50Hz.Technical OverviewStandard Operating Voltage: 220V–240V ACFrequency Requirement: 50 HzRegional Compatibility: This voltage specification makes it perfectly compatible with local mains grids across Africa, Europe, Asia, and the UK. It is not built to run natively on 110V–120V systems (such as those in North America) without a voltage converter.
