The Outwell Ecolux 24L is a luxurious electric cooler with a capacity of 24 liters, which is both useful on the go and at the campsite. The cooler has both a car charger and a connector for the regular power network. You can put 2-liter water bottles and some food into the cooler. On top of its cooling function, it also has a heating function that heats your food up to 60 degrees. Extra insulation in the walls and lid maintains temperatures longer, even when you disconnect it. This makes the cooler relatively economical. You can charge your phone with the USB port when the cooler is plugged in. Use the steel handle on top of the Ecolux to lift it. A light in the lid automatically turns on when you open the cooler. Note; a thermo-electric cooler cools with a fan. This fan makes a constant, soft buzzing sound.
