The mixture used in vapor products such as e-cigarettes is called e-liquid. There are also pod mod devices that use protonated nicotine, rather than free-base nicotine found in earlier generations, providing higher nicotine yields. The fourth-generation includes sub-ohm tanks (meaning they have electrical resistance of less than 1 ohm) and temperature control. Third-generation devices include mechanical mods and variable voltage devices. Second-generation devices are larger and look less like traditional cigarettes.

As such, using an e-cigarette is often called ' vaping'. Instead of smoke, the user inhales vapor. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank filled with liquid.
