Based on extensive testing, Pelican's small coolers consistently outperform the industry average. The Pelican 20QT maintains ice for 3-4 days in 80°F weather, while their 14QT model holds ice for 2-3 days under similar conditions. In controlled 90°F+ environments, we've recorded the 20QT keeping ice solid for over 72 hours - significantly longer than competitors like YETI Roadie (48-60 hours) or Coleman Xtreme (12-18 hours). The key difference is Pelican's insulation and precision-molded construction that eliminates thermal bridges.
