A butane burner is a portable cooking device that uses butane gas as fuel. It typically consists of a burner head, a fuel canister, and a control valve. These burners are popular for outdoor activities like camping and hiking, as they provide a convenient way to cook meals or boil water. Butane burners are lightweight and easy to use, making them ideal for on-the-go cooking. They produce a steady flame that can be adjusted for different cooking needs. Safety features, such as flame control and stable bases, help ensure safe operation during outdoor adventures.
