Unlike coolers that just offer insulation, the GUOER K2 can chill items in your car or on the go with a battery pack. It can cool items between 0º and 20ºC (32º to 68ºF), and it can also warm from 40º to 70ºC (104º to 158ºF). Its 6L temperature-controlled zone holds up to 8 cans, while a 2L storage area at its top carries items that don’t need cooling or heating.
