I have an esbit stove i use to boil water in my canteen cup and it works surprisingly quick. i prefer using trioxane because it lights quickly and in a survival situation, that would be alot better. although they are easily ruined due to oxygen exposure. I need to get a military poncho, i will try to with B-day money. I also carry 10 KATADYN MP1 tablets in my canteen holder. so, i can boil or purify any water i find.
