With a padded interior, reinforced seams, double zipper, and attached separate expandable pouch, the Hot Logic Lunch Bag+ has the look of an insulated lunchbox or thermal carrying bag. But it's so much more! It can cook frozen or fresh from-scratch meals or reheat leftovers at home, away from home, or on the go with a vehicle adapter. The ultimate kitchen accessory, the Lunch Bag+ does the work of standard appliances but with superior outcomes, greater convenience and higher performance with added space to carry all your extras. It uses Smart Shelf Technology, a patented low-slow conduction heating element, to bring food to the ideal temperature and hold them there until you're ready to eat. Ideal for preparing and transporting healthy meals and warm comfort food in the office, while traveling or at parties, potlucks, and gatherings. It evenly cooks or reheats fresh or frozen meats and vegetables and does not burn, dry your food or require monitoring. Simply place your meal inside, plug it in, and go about your day! It unzips and expands into a handy tote for carrying non-perishable food items, utensils, tableware and other accessories. It is compatible with most flat-bottom containers with sealable lids including glass, plastic, Tupperware, metal, aluminum foil, and cardboard.
