I am interested in the zippo 12 hour hand warmer to take in my bag on chilly nights.I like the idea of 12 hours of heat as the one litre of boiling water I’ve always usedis good for half the night.If you use one please send your comment

Check out the following review. It says "...the instructions state that a low temperature burn of the skin is possible if you don’t rotate position and allow it to remain on one part of your body. They also state not to use these while sleeping."

Thank you for that article.Its sounds like if I put it in a wool sock it will safely heat my sleeping bag all night.

The Zippo hand warmer uses combustion, and makes carbon monoxide. This is not safe to use indoors, let alone while sleeping.

If you're warm only as long as the hot water bottle stays warm, you need a warmer sleeping bag - there's no other solution here.

Cheers

The handwarner works ok with proper zippo fuel. 12 hours from cheaper fuel is pushing it.

It’s handy when sat around the fire, carving a spoon to maintain some dexterity. In its cover it sits in your pocket providing a little extra warmth.

As already stated I wouldn’t recommend it for sleeping in an enclosed shelter. It would be good for warming your bag before getting in.

used these (have 4 + 2) for years, super impressed. Rated 12 hours I have seen mine go over 24 hours. I usually leave them in my sleeping bag over night, then I leave them in my sleeping bag with my contact lens, and other freezables through the day, often on the same "charge" (fuel).

The only draw back is that I find them a pain in the ass to start (ignite) them.
