Question: I want it to heat water for coffee in a power outage. Can you put it out and re-light, or do you have to just let it burn out once lit?
Document: Light and easy to use. Edges are pretty sharp so be careful setting it up. I could see someone getting a pretty nasty cut from this thing. Bag makes it easy to find and comes with extra sterno and that is another plus. It is also big enough to add more sterno for longer periods. I ended up camping with 4 cans and the stove inside and it fit fine. Was skeptical at first until it boiled water for coffee.... then I was in love.
I tried this on a camping trip over the summer and was extremely dispointed. I wanted to boil water for my morning coffee. it did boil water but it took much longer than expected. The stand is very cheaply made and doesn't fold up well. I would look for an actual camp stove next time.
Some times I lose power do to car accidents or storms. I bought this as a back up at my house and when camping. Nice and light to carry and large enough to hold a pan. Just make sure u have safe and even surface if it is used at home.
We live in south florida and you just never know when you are going to lose power. I purchased this kit as a back up in the event of a hurricane or any other event that would cause a power outage. Very small and compact but good enough for reheat and cook meals on it. I would strongly recommend to have around as a back up and also a nice addition to your bugout bag.
Our local power company recommended we acquire a means of cooking during a power outage in preparation forSuper Storm Sandy. Local stores were sold out. We were fortunate that our power was off this time for less than 24 hours because this stove could not get here before the storm arrived. But we are ready for the next one! Since we have not actually used it yet, I am rating it average. I would have nothing to compare it to as this is our first.
This stove is perfect for rough camping. Stove sets up easy and holds a coffee pot or skillet for cooking. Folds back down and away for easy carrying. I use sterno for the fire. I recommend.
I purchased this for emergencies--a stove I could use safely inside. I have a Coleman propane stove, too, but that is really for outside use. My power goes off fairly frequently, so this is important! I like that it is in its own small bag, and has enough room for the stove and two or more cans of Sterno. I bought extra cans of Sterno, too,  of course.
This stove kit is very compact and easy to use. the light weight and carry handle makes for easy storage and packing
I bought this stove to have on hand for power failures at home. I tested it out and found that the sterno burns hotter than I expected. I plan to pick up a couple extra cans of sterno as they say one can lasts about 2 to 2.5 hours. There is plenty of room in the bag for more cans. I showed my wife and kid how to set up and use the stove in case I am out of town when they need it. It seems very safe to me.
Have had this for about six months and have used it twice when electricity was out. Only used it for heating water and a can of soup but was well satisfied with the results. Having the case worked out well with putting 2 more cans of Sterno, waterproof matches in a plastic case and lighter, just grab it and your ready. Nice addition to my emergency supplies.
Answer: you can put it out and then reuse it over and over....
