❓ How long does ice last in a cooler?
Budget coolers: 1–2 days. Mid-range coolers: 3–5 days. High-quality rotomolded coolers: 5–10 days. To keep the ice fresh longer, pre-chill the cooler, use block ice, and open the lid as little as possible.
❓ What size cooler do I need?
Day trip on your own: 20 liters. Weekend for two: 35–45 liters. A week of camping with the family: 65–75 liters. Keep in mind that ice takes up about 30–40% of the space.
