This review delves into the reheating performance of the Buddew 70W electric lunchbox, specifically focusing on its capabilities when powered by a 12V power station, a departure from the standard 240V mains power. We tested the lunchbox's ability to heat a 600g meal – 500g of chicken curry and 100g of soba noodles – initially chilled to 10°C. This real-world test provides a practical assessment of the lunchbox's efficiency and effectiveness in a lower-voltage scenario, mimicking situations encountered during camping or other outdoor activities where access to mains power is limited.The experiment meticulously tracked the food temperature at various intervals, monitoring the power consumption of the 12V power station. This allowed for a comprehensive evaluation of the lunchbox's heating speed and energy efficiency. The results offer insights into the practicality of using the Buddew 70W lunchbox as a reliable and convenient option for reheating pre-prepared meals in situations where conventional power sources are unavailable, highlighting its suitability for travelers and outdoor enthusiasts.
Pros And Cons
- Reheats food effectively using a 12V power source.
- Reached a temperature of 100°C in 45 minutes using 12% of a 518Wh power station.
- Safe reheating temperature of 70°C reached in 30 minutes.
- Food may stick to the bottom of the tray if left unattended for extended periods.
- Heating time may vary depending on the food consistency and initial temperature.

Reheating Chicken Curry and Noodles
This review focuses on reheating a meal using the Buddew 70W electric lunchbox, powered by a 12V power station. The meal consisted of 500g of chicken curry and 100g of soba noodles, both pre-cooked and refrigerated.

Initial food temperature was 10°C (50°F), while the ambient kitchen temperature was around 19°C (66°F). This test aimed to determine the lunchbox's reheating capabilities on a lower voltage power source than the typical 240V mains power.
The lunchbox was loaded with the food, and the 12V power station, already at 100% charge, was connected.
30-Minute Reheating Test and Observations
After 30 minutes, the food's temperature was checked using a probe. It registered 80-85°C (176-185°F), indicating significant heating.

The food was stirred, and a taste test confirmed it was warm, but not yet fully heated. The heating process started at 45 Watts and gradually increased to 65 Watts over 15 minutes, eventually reaching a consistent 72 Watts for the remaining time.

At this stage, the power station had used only 9% of its total capacity, showcasing the lunchbox's energy efficiency.

Final Results and Overall Impression
After a total of 45 minutes, the food reached a temperature of 100°C (212°F), utilizing only 12% of the power station's capacity. This exceeded expectations.

The taste test confirmed the food was piping hot, demonstrating successful and efficient reheating. The lunchbox achieved a safe reheating temperature in a reasonable time, proving to be a convenient option for reheating meals on the go.
Although it's not a cooker, it's ideal for reheating pre-prepared meals. The slow cooking aspect allows for flexibility, making it suitable for camping or other outdoor activities.
