America 3-Prong NEMA 6-15P plug to NEMA5-15R Female Socket Power adapter.this is a NEMA 6-15 Plug with 1 round, 2 horizontal blade input ,US 3-Pin NEMA6-15P Male to Nema 5-15R 3-Prong Female AC Adapter This adapter is great at doing what it was designed to do: it lets you BYPASS A CRITICAL SAFETY FEATURE of North American plug design. That is, it lets you plug a 120V male plug into a 240V female receptacle. That means whatever is on your appliance side could potentially be exposed to 240V and therefore must be rated to handle that. Valid use cases are things like dual voltage EV chargers, or making a 120V extension cord or power strip work with 240V supply and devices. Note:This adapter will not transform voltage or current.NEMA6-15 corresponds to 240V devices, and NEMA5-15 corresponds to 120V devices. Please carefully check whether your device is suitable for the corresponding voltage (240V or 120V) before use. Otherwise, it may cause equipment damage. Rated up to @15A 25
