In 1979, Casio made a calculator that doubled as a cigarette lighter, a.k.a. the "calculighter' : pics

From another site...

The Casio QL10 is a standard refillable lighter 4″ tall, with 4-function calculator, multi-alarm clock, two time zones and stopwatch. It lasted all of one season in Casio’s 1980 line and retailed for around $90 at the time and was dubbed a Calcu-Lighter by the press. Calculator makers pushed the envelope after perfecting miniaturization and the LCD display system, so it was only logical to package a lighter within a calculator during the pro-tobacco days of the 80's.

    Gotta come clean: I've always wanted to vape my phone. So I understand the impulse.
