6.1 Heating Your Meal

1. After preparing the lunch box as per the Setup section, open the steam cap on the lid. This is crucial for proper heating and safety.
2. Select the appropriate power cable for your environment:
   • For car use (12V), plug the car adapter into your vehicle's cigarette lighter socket.
   • For truck use (24V), plug the truck adapter into your vehicle's power outlet.
   • For home or office use (110V), plug the standard power cable into a wall outlet.
3. Connect the chosen power cable to the corresponding port on the lunch box. The indicator light will illuminate, signifying that heating has begun.
