Litheli has announced a unique product - the FrozenPack wireless backpack cooler. It is designed to carry chilled drinks and food. The backpack has a capacity of 16 liters and is able to maintain the temperature down to -20 °C for 6 hours thanks to the built-in battery. When the power goes out, the insulated design keeps you cool for another 4 hours. The FrozenPack cools down in just 15 minutes and operates quietly, with a noise level of less than 35 dB. In Eco mode, the unit can function for up to 8 hours. The FrozenPack is equipped with adjustable straps, pockets and mesh holders. The interior space is optimized to hold up to 10 large cans or several packages of frozen food. The cooling power can be adjusted via the control panel and the display shows the current temperature and battery level. The unit can be plugged directly into a power source or you can use the On-The-Go kit with 2 replaceable batteries. The FrozenPack is priced at $277 on the crowdfunding platform Indiegogo
