Frequently asked questions
- Can I heat food without a microwave?
- Yes. The electric lunch box heats the container with its own heating element, so you don't need a microwave or kitchen. You just need to plug it into the power or the car depending on the model.
- Does it work in any car?
- The 12V model is designed for the cigarette lighter socket, common in cars. If your vehicle uses another voltage, check compatibility beforehand.
- How long does it take to heat food?
- It depends on the power and the amount of food. A 90W model with 3.5L capacity is designed to heat a full meal, while a 470ML one heats smaller portions.
- Can the container be washed?
- 304 stainless steel models are the easiest to clean. It's advisable to separate the electrical part before washing the container.
- Is it good for taking food to work?
- Yes, as long as you have an available outlet or use a car-compatible model. It's a practical alternative to the office's shared microwave.
- What's the difference from a tray sealer?
- The semi-automatic 9-tray sealer is equipment for sealing and preserving food trays in volume, not for heating your personal lunch. They are different uses.
