Frequently asked questions
- How long does it take to heat food?
- It depends on the model and the amount. The TINSOL declares 90W; in general, these lunch boxes take between 20 and 40 minutes to heat a portion. Don't expect microwave speed.
- Can it be used in the car and at home?
- Yes, some models allow it. The TINSOL specifies 'Car or Home' connectivity. The 12V Car & Home model is plug-in, so check the plug type before buying.
- Is it dishwasher safe?
- It's not indicated in the available specifications. For 304 stainless steel, manual cleaning with water and soap is the safe option.
- Is the 9-tray sealer worth it?
- Only if you need to seal portions for sale or large-scale meal prep. For heating the day's food, it's not the right option due to price and function.
- What's the difference between the 470ML and the TINSOL 3.5L?
- The 470ML is cordless and compact, ideal for one portion. The TINSOL has 3.5L and 90W, designed for larger meals and with car or home connection.
