Electronic cigarettes with touchscreen

 

— a display that allows you to control an electronic cigarette (more precisely, a battery mod) directly by touching the screen — just like in a smartphone. Such control is more versatile than conventional mechanical buttons and switches: you can display a variety of controls on the screen and bind almost any battery mod functions to them. Also note that touch displays are usually quite large (otherwise comfortable control would be impossible) and are made in colour, which makes life even easier for the user. On the other hand, such a screen is expensive, consumes a lot of energy (which affects the operating time), and besides, it cannot be controlled by touch.
