I can only imagine the poor kids, raised with such a device, whining they will go hungry because the battery went dead and they had no way to cook the marshmallow.
Their non survivalist parents would probably try and find a mini mall at 11 pm so junior could get another device.
Not in my household.

And by the way, despite what the electric marshmallow cooker consumer may say, in the shadowy corners of civilization, there's always someone with no marshmallows wanting to take yours. Stay safe out there.
