Food can stay cold in a cooler without ice for about 4 to 6 hours, if the cooler is high quality and pre-cooled before use. To extend this period, fill it with cold or frozen items. The outside temperature plays a crucial role; on hot days, the duration will be shorter. Maximize cooling efficiency by keeping the cooler out of direct sunlight and avoiding opening it frequently. For longer periods, consider using ice substitutes like frozen gel packs or DIY ice packs to keep contents cold for 24-48 hours.
