A:Answer Hello Paco, thank you for your question. The Insignia NS‑CF44SS6 mini fridge must be plugged directly into a grounded 3‑prong wall outlet, as it requires a proper 115V/60Hz power supply and should not be connected to surge protectors, extension cords, or ungrounded adapters. This ensures safe operation and stable performance of the refrigerator. Mueez | Insignia
