Food not kept above 60C or below 20C, must be consumed with 4 hours to prevent food poisoning.
Above devices are just gimmick unless it's has a good vacuum seal & well insulation.
7am to 1pm , if in between , can keep the heat by pressing reheat.
Haven't try how good is the vacuum insulation.
Can press few times if not hot.Just use a charger to charge it.

Contain battery means exploding risk, especially when it involves heat and to make heat u need high electric output another risk.
Just get a good vacumm sealed lunchbox like from Thermos and ur food will be kept hot enough.
Now , most of the electronic also contain battery build in.
I though most electric output like oven , microwave and streamer all need electric output ? what do you mean risk ?
If someone use it , maybe can dissemble the battery and check whether it's high risk or not.May even replace with better battery.
Cannot find those Thermos.The whole year can't even find a lunch box rectangular type.All of the thermos just a round soup mug , how to eat put food inside , if noodle still possible but rice and dishes , not possible.
If you found one , please let me know

rule namba 1.. properly cook and reheat your food...
low heats like that PALATsites wont die...
you're just asking for trouble if food kept for long and bacteria starts to grow....
I knew that , the food is properly cook and hot.Sometimes stream it to 100'c at the morning.
Still need to put into the lunch box for afternoon consume.How do reheat it ?
If vacuum , bacteria will grow that fast and in the middle reheat again will be a better.

Nope, that one need 3 pin wall socket power , don't have build in battery.Except you use car battery which will drain your battery.
No one use or saw one of this lunch box ? It should be very popular during covid time since no dine in allow , only take away.

Should have at lease someone bought it before.
Beside, I am sure there are people here bring cooked food with lunch box for lunch meal.Can share what type of lunch box you all use ?
