Just curious :

Is there any difference, carbon monoxide wise, between using a camping propane stove and using the gas cooker in my kitchen ??

That question apart, yes, I also have various electrical lighting sources (battery operated).
But I want an easily (long term) stored fuel, which can be used both for cooking and for area lighting.
And yes again, you are right : any open flame device has to be supervised + carbon monoxyde has to be monitored.
