The Anker Everfrost Dual Zone Powered Cooler offers a simple, streamlined solution for keeping our food and beverages cold for weekend camping trips and RV adventures. The 53-liters of space features Dual Zone technology, splitting up the cooler into two independently controlled compartments that can both act as a fridge or freezer for maximum convenience. Since the cooler utilizes a battery-powered compressor to stay cool, there's no need for runs into town to grab new bags of ice and more storage space to pack up our goods. The battery can easily be removed and recharged via wall outlets, car sockets, USB-C cables, and solar panels so we can stay powered up on the go, and the battery lasts up to 27 hours to keep our cargo cool all day long.
