78 views
Food will stay frozen in a cooler with ice packs for generally 24 to 48 hours, depending on factors like cooler quality, outside temperature, and how often the cooler is opened. To maximize duration, pre-chill the cooler and food, use multiple ice packs, and minimize opening. Dry ice can extend this period further but should be handled cautiously due to its extreme cold.
