Portable heated lunch box

The heated lunch box contains two 1.5-liter detachable 304 stainless steel containers that can be interchanged daily. It can also be heated by two people taking turns using the base in the wild. Heating is faster and more uniform, with a heating time of 25-40 minutes. The lid of the lunch box has a sealing ring to prevent liquid from flowing out, making it safe to use while driving.
