In product photo number 4, you can see the power cable and yes, it plugs into a wall socket. This is what the whole cable looks like: Nedis Câble d'alimentation IEC-320-C7 (3m) (is included in the delivery)
...my husband is thrilled with this lunch box. No more eating cold because he is out. A good 30 minutes before lunch, plug in the lunchbox "with power cord, is included" turn on, then food is food, my husband said, "it will be hot". We have had a good experience and would buy it again. Washing up is also super easy. The lunch box also comes with cutlery.
No it does makes the food warm but it takes ages to warm it up, it took me around 30min at my desk to warm up rice with chicken und vegetables. If you do not mind waiting, go ahead. Otherwise I would go for a normal box and use microwave.
