Butane lighters are refillable and use pressurized butane fuel, while torch lighters are not refillable and utilize a small flame created by an internal catalytic reaction to light cigars. Butane lighters provide a consistent source of heat, with adjustable flame height, which can be used for precision lighting and cigar touch-ups. Torch lighters offer an intense heat that is ideal for initial lighting or larger ring gauge cigars. Torch lighters are generally more durable than butane models due to the absence of any refilling components.
