They describe them as food warmers.
That's the problem here, there are many possibilities and I have no idea what the final results will be.
I'm guessing the good old bain-marie will provide the best results and the fact that it's electric makes it even better, safer and easier to use. This one seems nice:
The electric bags seem are extremely portable and easy to store but I seriously doubt they can heat up and keep the temperature properly.
I'm not so sure about portable ovens anymore, maybe they will dry out the food...
