The titanium Triad XE was designed with ease of use in mind. The stove burns either alcohol or fuel tabs. Alcohol is used by filling the center container and then placing a few drops between the inner and outer container. Light the outer drops of alcohol and the stove primes immediately (or) if alcohol is unavailable, remove the inner container for the perfect fuel tab stove. Boils 2 cups of water in 5.5 min. Holds 1.2 oz of fuel for up to 15 minutes of burn time. Dimensions: 3"D x 1" high (closed), inner canister is 2.5"D x .63"H. Weight: 1.5 oz.
