IMTEST tested four coolers for camping and travel: EcoFlowⓘ Glacier Classic 35, Dometicⓘ CFX5 45, Anker Solix Everfrost 2 40L, and Maentum IcecubeX 40L. The winner was the EcoFlow Glacier Classic 35 with a rating of 'good' (2.53), which cools to 7°C in 17 minutes and maintains temperature for over 40 minutes. The best value for money was the Maentum IcecubeX 40L (2.54), though it cools slower (about 51 minutes) and lacks a built-in battery. The Dometic CFX5 45 (2.56) had the fastest cooling (under 10 minutes) and best insulation, but is more expensive and requires an external battery.
