Default Lunch Box Warmer battery powered

Hello,


I'm searching for a lunch box battery powered, something that I coulde use where there isn't any power source (e.g. mountains or desert) and which could be turned on by a button for example.
It must be rechargeable (e.g. the evening of the day before using it).
Any ideas? Thanks

How warm are we talking...?

Honestly, most things that need to be warmed up need to be chilled down... Lunch box with ice packs inside it to keep food cold causes condensation, and when you go to turn it on could get a nice shock...

Have you thought about small portable stoves that use small cylinders of propane to heat your foods?

Battery powered systems, well, that's gonna need a lot of power, and be pretty hard on a battery over time.
