Never Carry Fuel Again! The KELLY KETTLE was pioneered by the Kelly family in Ireland more than 100 years ago. The kettle uses any natural fuel such as bark, twigs, pine cones, and leaves to heat the water inside the double walled chimney. The fuel is at the base and it draws air in through the base hole and the heat will draw more air as it escapes out the top of the chimney with a type of forced convection. This creates a hot jet as air passes through rapidly, making the cooking process quicker.

Types of Kelly Kettles Base Camp (Large): Holds 54 oz., comes in aluminum and stainless steel Scout Kettle (medium): Holds 44 oz. Only comes in aluminum Trekker (small): Holds 17 oz. and comes in both aluminum and stainless steel *the kettle I am reviewing* Time to cook water to boil? It takes me about 3 minutes from time of ignition to boil with the trekker (small) kettle. I can make myself two decent size cups of tea or provide more than enough hot water for a meal. Thoughts on aluminum: Some people do not want to use aluminum for health reasons, and I certainly do understand this. Regardless, I have tested the aluminum version while in Iraq with the Army, and I could make hot tea in a few minutes and be sipping it and relaxing before the Iraqi soldiers even had their chai stove set up. My impressions of the stainless: This is a better version if you are intending to be more rough. It's a better pack kettle because it won't dent like the aluminum will, and my aluminum kettle is well dented. The downside is the added weight, but it isn't a large amount of difference (1.3lbs vs. 1.7lbs). How to use: Remove the cork, fill with water in the chimney nozzle until full, prepare the base tinder and place the kettle on the base. Add more fuel material through the top of chimney. You can either ignite the tinder before or after setting kettle on the base. Sometimes, I will set the kettle on the base and ignite the tinder, then blow into the base hole for a couple seconds to give it an added boost to catch. The kettle will take it from there. I do not need to add more material for fuel than what can easily fit one time. The water will boil very quickly. Add-ons and accessories: I am not going to sign off on these additional features 100% because I do not find the cooking capabilities to be adequate for my needs. However, a cook set could work in a pinch. Reliability: I see no reason why the stainless kettle shouldn't last a lifetime. I have had the stainless for only a couple years approximately, but the aluminum for much longer. The aluminum is not as durable, but with care it can last a long time. The BASE for the kettle will need to be replaced! This is because the fire is always burning in the base. Over time, it will wear out. So far, my aluminum base has not worn out, and I have made hundreds of cups of tea from it. Fortunately, you can buy a replacement base at Kelly Kettle any time. You can buy either the kettle with base or a kettle/base with cook set combo. I would check for sales and special promotional offers, but the prices are reasonable for the level of quality. *IMPORTANT* -- always thoroughly wash the kettle, inside and out when you first receive it new. The metal particles, dust and residue from manufacturing can be nasty. I usually utilize Thermos cooking, and the kettle will boil my water in a few minutes so I can add the water to my Thermos with my rice or soup mix, then I can prepare my tea and finish setting up my hammock. I will have my camp set up and a hot meal waiting for me in no time. My overall rating: (5 stars) The Kelly Kettle is the only kit I go to in the field to make hot water.
