For sure, this would be useful, specially when you are not finding it in yourself to go to the kitchen, use the stove or oven and change the plates etc etc (that happens sometime), do everything then and there. And yes, useful for outdoor activities too.
BTW, what is the recharge time and discharge time, @anayakhan?
It's charging time is 4 hours and it can keep food warm upto 3 hours. Thank you for support @mobi72 and everyone here on STEEMHUNT:)
4 hours of charging time is understandable, heating needs more power, its battery must be of somewhat big wattage? 3 hours working time is great.
