1. Prepare Food: Place your cooked food into the stainless steel container. For best results and to prevent drying, add a small amount of water (1-2 tablespoons) to your food, especially if it's rice or pasta.

   • For car/truck (12V/24V): Use the provided DC car adapter cable.

   • 110V/220V: Approximately 15-30 minutes.

6. Troubleshooting

• Food not heating:
  • Ensure the power cable is securely plugged into both the lunch box and the power source.
  • Verify the power source is active (e.g., car ignition is on, wall outlet is functional).
  • Check if the indicator light on the lunch box is illuminated. If not, try a different power cable or outlet.
• Uneven heating or scorching:
  • Add a small amount of water (1-2 tablespoons) to your food before heating to help distribute heat and prevent drying.
  • Stir the food halfway through the heating process if possible, to ensure more even heating.
  • Ensure the steam vent is open during heating to prevent excessive pressure buildup.
• Lid not sealing properly:
  • Check for any food debris or obstructions around the silicone seal.
  • Ensure the lid locks are fully engaged on both sides.
