I think you would get the same effect from embers carried in a container full of ash.
(If you have something like this just to carry a fire it seems to me you might be better just packing a lighter with you.)


I forgot about those: Charcoal Handwarmer

Still, having a "purpose built" item is in line with being prepared. Otherwise you are relying on finding a field expedient substitute.

And, it is still a hand warmer. Not a bad item to have at times.
