In a power outage, food will stay frozen in a freezer for approximately 48 hours if the freezer is half-full and 24 hours if the freezer is full, assuming the door is kept closed. It's vital to avoid opening the freezer to maintain the cold temperature. To prepare for longer outages, consider filling empty spaces with water bottles to help keep the freezer full and cold. Check food for ice crystals or temperature below 40°F (4°C) before refreezing or consuming after power is restored.
