Food can be heated using an electric lunchbox instead of a microwave or any other type of heating apparatus. Obviously, a power source is needed to heat food in electric lunch boxes, which have plugs connected to power cords. Electric lunchboxes have numerous drawbacks despite how convenient they may seem. Each time you want to heat meals, you have to go in search of a power source. These tiffin trays are unsafe for children to use because electricity is involved. Actually, schools forbid the use of electronic lunchboxes, just like any other gadget. In addition to the possibility of getting shocked, burning the fuse, and damage to the cord and plug, utilising an electric lunchbox carries additional risk.
