Operating Instructions

Heating Food

  1. Place your prepared food into the 304 stainless steel container.
  2. If your food is dry, you may add a small amount of water (1-2 tablespoons) to the food to aid in steam heating and prevent scorching.
  3. Securely close the lid of the lunch box, ensuring all four clips are fastened.
  4. Open the steam outlet vent on the top of the lid. This is crucial for safe operation during heating.
  5. Connect the appropriate power cable:
    • For home or office use, use the 110V/220V AC power cable.
    • For car or truck use, use the 12V/24V DC power cable.
  6. Plug the power cable into the corresponding power port on the lunch box and then into a suitable power outlet (wall socket for AC, cigarette lighter socket for DC).
  7. Press the power button on the front of the lunch box. The indicator light will illuminate, signifying that heating has begun.
  8. Heating typically takes 20-25 minutes for warm food and 25-30 minutes for cold food. Actual heating time may vary based on food type, quantity, and initial temperature.
  9. Once heating is complete, unplug the power cable and close the steam vent before opening the lid.
