A seemingly paradoxical device, a pocket calculator with a built-in lighter function, emerged as a novelty item, primarily during the late 20th century. These devices combined the functionality of a basic electronic calculator with a butane lighter, typically located on the upper edge or side. Examples often featured a standard numerical keypad, basic arithmetic operations, and a small display screen alongside an ignition mechanism for the lighter.
The appeal of this combined gadget stemmed from its compact nature, offering two commonly used tools in a single, pocketable unit. This provided a practical convenience for individuals who frequently used both a calculator and a lighter. While not widely adopted as essential tools, they represent a distinctive period in consumer electronics, showcasing a trend toward multi-functional gadgets. Their existence also illustrates the evolving landscape of disposable lighters and the integration of electronic components into everyday objects.
