【Heats Faster】: Professional heating elements provide powerful heating power for this heated lunch box. Warm it up 25 to 30 minutes before eating and you'll have a hot lunch instead of a cold sandwich or fast food. Tip: It is recommended to add some stock or water to the food for faster and more even heating. 【Good Sealing】: Many heating lunch boxes for men's work use cheap materials in order to save costs, resulting in poor sealing effect. We use thicker rubber gaskets and four stronger clips to ensure good vacuum insulation. The delicious soup can be enjoyed outdoors anytime without worrying about leakage. 【Keep Food Safe】: This portable working lunch box warmer is made of food-grade pp plastic and 304 stainless steel detachable container. Even if it is heated to a certain temperature, it will not produce substances harmful to health. Easy to clean and dishwasher safe. 【1.8L Large Capacity】: An insulated lunch box specially designed for big appetites. 61 oz/1.8 liters is roomy enough for any type of meal you like. An extra 0.45L food grade pp plastic box can store fruit and salad. A hot and nutritious lunch will make you happy and energetic. 【Ideal Gift】: Are there often family members or friends around you who are too busy with work to have a steaming lunch? This electric lunch box supports home/office/cars and trucks. Stop eating cold meals and unhealthy food on weekdays. It will be the most suitable gift for construction workers, truck drivers, office workers and other people who want to bring their own lunch.
