Glossary of Terms Related to E-Cigarettes

Term Definition
advanced personal vaporizer (APV) Generally used to refer to second- or third-generation e-cigarette devices with regulated variable voltage or variable wattage, APV can also be called a mod.
analog (slang) Combustible tobacco cigarette.
atomizer The atomizer is the component in an electronic cigarette that is responsible for heating the e-liquid to the point of aerosolization. The atomizer contains the heating coil and wick. It is most often contained within the metal, glass, or plastic housing called a cartomizer, tank, or clearomizer, which is screwed into the battery.
base liquid This is the liquid to which nicotine and flavoring are added to create e-juice. The two most common base liquids are glycerol and propylene glycol.

Term Definition
battery The battery is used to power an electronic cigarette’s atomizer, and is usually a rechargeable lithium ion battery available in a variety of sizes/capacities expressed in mAh, commonly in 600, 900, and 1,100 mAh.
cartomizer A combined atomizer and cartridge, the cartomizer combines a heating element and a juice delivery system into a single unit. Cartomizers can be made of plastic, metal, or a combination of both. They are disposable and not considered to be refillable, although some users manage to do so. Cartomizers can come in single-coil, dual-coil, or multiple-coil configurations. Having more than one coil produces twice as much aerosol or the same amount twice as fast from the standard. There are top-coil and bottom-coil configurations.
cartridge The mouthpiece that contains the absorbent filler material soaked with e-liquid. This is a plastic or metal covered part of an e-cigarette, primarily of first-generation devices. A single cartridge contains about 1 ml of e-liquid.
cigalike An electronic cigarette having a form factor similar to a combustible tobacco cigarette. It is generally considered to be the first generation of e-cigarette products.
clearomizer A cartomizer that is made of a clear material (usually plastic, Pyrex, or glass) so that the user can see the quantity of e-juice remaining in the unit. Many have milliliter graduations for the capacity of e-liquid left. The common capacity of clearomizers varies from 3 to 6 ml.

Term Definition
coil/heating coil A coil is generally a piece of nichrome or kanthal wire that has been wrapped around a wick. Current flows through the coil; the coil gets hot and aerosolizes e-liquid. Cartomizers can come in single-coil, dual-coil, or multiple-coil configurations. Having more than one coil in an atomizer results in increased production of aerosol as compared to single coil.
disposable e-cigarette The disposable e-cigarette is designed to be used once and usually comes with no charger. It is a single-piece e-cigarette device.
do it yourself (DIY) Commonly used to refer to preparing and customizing your own e-juice or refillable solution.
dripping Putting e-juice directly on the atomizer.
dry puff This refers to the unpleasant taste reported by an e-cigarette user when not enough e-liquid is supplied to an atomizer or cartomizer, resulting in poor aerosol and flavor.
e-cigar E-cigarette device designed to resembles a traditional tobacco cigar in shape.
e-juice, e-liquid The liquid that produces the aerosol in an electronic cigarette. E-liquid is aerosolized by the heating element, and generated aerosol is inhaled by the e-cigarette user. Typically contains glycerol, propylene glycol, nicotine, and flavorings.
e-pipe E-cigarette device designed to resemble a tobacco pipe.
flavoring The flavorings used in e-liquids, which are usually the same flavorings used in food and drinks. Certain ingredients (particularly sugars and sweeteners) are avoided, however, because of the damage they can do to atomizers.

Term Definition
mod Short for modification. This originally referred to modifying a flashlight or a battery to be used in vaping, but is now commonly used to refer to any vaping device of second or third generation that is not a cigalike.
pen style A style of first-generation e-cigarette device that resembles a pen.
personal vaporizer The entire e-cigarette device; usually refers to second- and third-generation products.
starter kit A kit that includes basic e-cigarette equipment, typically a battery, cartomizer, charger, and instruction manual for the user.
sub-ohming Sub-ohming involves vaping using an atomizer coil with a resistance of <1 Ω. This increases the overall power output (wattage) of the device allowing more energy to reach the coil which, in turn, heats up faster and reaches a higher temperature so more aerosol is produced.
tank The part of second- or third-generation e-cigarette that holds the refillable solution. Tank is a common name for a refillable clearomizer and it usually holds more e-liquid than cartridges and it is usually manually refilled with e-liquid by the user.
throat hit The sensation on the back of the throat that e-cigarette users commonly report after taking a puff on an e-cigarette.
vape/vaping The act of using an electronic cigarette. The equivalent of “smoking” for combustible tobacco cigarettes.
vaper Someone who uses an electronic cigarette (a person who vapes).

Term Definition
vaper’s tongue Used by experienced e-cigarette users to describe the sensation of not being able to taste the flavor in e-liquid when inhaled.
vaporizer Used by experienced e-cigarette users to refer to their e-cigarette device.
variable voltage/variable wattage E-cigarette with variable voltage or variable wattage allows users to control battery output voltage or power of the e-cigarette. Increasing the voltage/wattage leads to increased coil temperature and, as a result, increased production of aerosol.
wick Deliver e-liquid to the coil in electronic cigarettes. Most commonly made from silica cord, the wick can also be made from rolled-up steel mesh, ceramic, fiberglass, cotton, or a host of other materials.
wire Generally refers to resistance wire used in building coils for atomizers.
