Butane lighters are portable devices designed to produce a controlled flame, typically fueled by butane gas. They are commonly used for lighting cigarettes, candles, grills, and other items requiring fire. These lighters consist of a small chamber that holds the butane, a valve to release it, and a spark mechanism to ignite the gas. Butane is favored for its clean-burning properties and portability. Refillable butane lighters are popular due to their cost-effectiveness and sustainability. They are compact, easy to use, and widely available in various styles, from basic models to more advanced, wind-resistant designs.
