Even in temperatures as high as 90°F (approximately 32°C), the interior maintains a temperature of approximately 1°C, keeping ice for 24 hours (as proven in Arizona desert tests). It also works well with gel ice packs, which last longer than regular ice cubes, helping to keep food and drinks fresh for longer.
