Operating Instructions
Follow these steps to heat your meal:
- Connect Power:
- For home or office use, connect the AC power cable to the appropriate port on the lunch box, then plug it into a standard 110V/220V wall outlet.
- For car or truck use, connect the DC power cable to the appropriate port on the lunch box, then plug it into your vehicle's 12V or 24V cigarette lighter socket.
- Start Heating: Once connected, the indicator light on the lunch box will illuminate, signifying that heating has begun. The lunch box will automatically maintain a constant temperature.
- Heating Time: Heating times vary depending on the food type, quantity, and ambient temperature. Generally, food will be warm in 25-30 minutes in summer and 40-60 minutes in winter. For best results, allow sufficient time for heating.
