3 Piece:  Term used to identify a three piece electronic cigarettes.  This consists of a battery, atomizer and cartridge.

510: One of the most popular threading connection used by electronic cigarette brands.  The 510 thread usually applies to the battery connector and the tank or cartridge.

Ω:  Ohms.  A measurement of resistance.  Applied to electronic cigarette atomizers, the lower the ohms, the less resistance.  This equates to a hotter coil which creates more vapor.


Above-ohm vaping – Any coils rated at 1.0 ohms or above.

Advanced Personal Vaporizer (APV):  Also known as a Mod for modified electronic cigarette. An APV normally includes a larger, more powerful battery and the ability to adjust voltage and/or wattage.

Air Flow:  The ability to adjust the amount of air input when you take a draw.  The more air flow the easier to take a draw and more cloud production.

Analog:  A vaping term when referencing traditional cigarettes.

Atomizer:  An assembly containing a heating coil, wick and bridge.  The coil is heated up by activating the battery.  When e Liquid makes contact with the atomizer it turns into vapor.

Automatic: This term pertains to a style of battery in which no button is used to activate the atomizer.  The battery is automatically initiated when it senses the user taking a draw.  Automatic batteries are mostly used with cartridge atomizers and the vaping experience most closely resembles traditional smoking.

Automatic Shutoff:  A feature used in smart batteries.  This prevents inadvertent discharge of the battery.  If the battery is turned on past the ten second mark, it automatically shuts off.


Battery:  A portable power device which you connect to your cartridge, cartomizer or tank.

BCC:  Acronym for Bottom Coil Clearomizer.  The atomizer is situated at the bottom of the tank.  This location is preferred by many who vape.

BDC:  Acronym for Bottom Dual Coil Clearomizer.

Box Mod:  A vaporizer typically in a box or rectangular shape.  Box mods can be above-ohm and sub-ohm and tend to have variable voltage, variable wattage.  Newer box mods have temperature control.

BVC:  Acronym for Bottom Vertical Coil


Cartridge:  Similar in shape to a filter for a traditional cigarette.  This plastic tube contains absorbent material soaked in eLiquid.  Cartridges were popular in the first generation ecigs and have since been mostly replaced with cartomizers.

Cartomizer:  A plastic tube consisting of a cartridge and atomizer.  The two components are connected in one disposable unit.  Usually the eLiquid will run dry and the user throws the while cartomizer away.

CCT: Custom Curvature of Temperature: Quickly heats and cools the TC coil to allow them to work optimally.  This mode is found in mods such as the Vaporesso Tarot Pro.

CCW: Custom Curvature of Wattage:  This mode adjusts the ramp up time of the coils in wattage mode.

Cig-a-like:  A term to describe electronic cigarettes which resemble traditional cigarettes in shape and size.  Some common cig-a-likes include Green Smoke and EverSmoke.

Circular Charger:  A charging platform which is powered by a USB or wall connector.  The platform allows for specially designed batteries to rest in a vertical position for charging.  Usually a light emitting around the circumference of the charger will turn from red to blue when the battery is fully charged.  Some models which use this feature are iGO4 and VaporFi Pulse.

Clearomizer:  A transparent cartomizer

Cloud Chasing:  A term to describe Vapers who love to create a large amount of vapor.  Usually this is accomplished with RDAs.

Cotton:  Preferred by experienced Vapers when using RDA to soak e Liquid.  Cotton creates more vapor than the typical wick.  It is important to use natural cotton without any dyes or chemical additives.  Boiling before use is also recommended.

Coil:  The wire which is heated up causing the e Liquid to turn into vapor.

Custom Blending:  Mixing an assortment of various e Liquid flavors into one bottle.


DCT:  Dual Coil Tank

Direct Lung Hit (DLH):  The act of inhaling the vapor directly from the atomizer into your lungs and not letting it rest in your mouth.  This style of vaping is usually done with sub-ohm devices.  For above ohm devices, the user will normally do a Mouth to Lung (MTL) hit.  This is the typical inhalation used when smoking a cigarette.

Disposable e-cig:  An electronic cigarette designed for a one time use.  Once the battery and/or e-Liquid is drained, the device is thrown away.

Drip Tip: Drip Tips are usually metal or plastic mouth pieces which are used in place of the cartridge.  Drip Tips allows you to drop e Liquid directly on to the atomizer.  No more than 4 drops are required when using this method.

Dripping:  The act of placing e Liquid drops on an atomizer.


e-cig:  An abbreviated form for electronic cigarette.  There are other variations such as eCig, e cig, ecigarette or e cigarette.

eGo:  One of the most popular e-cigs produced.  The eGo mainly comes with a 650 or 1,000 mAh battery and a 510 threaded atomizer eGo e-cigarette consists of a long 1000 mAh battery and/or a short 650 mAh battery.  Variations in the eGo include the eGo-T or the eGo-C (which denotes how the atomizer heats the eLiquid.  The eGo-Twist is a variable voltage eGo battery which is adjusted by twisting the end cap to the desired voltage.

e-Juice:  Another term for e Liquid.

e Liquid:  The liquid which is heated by the atomizer creating vapor.  The e Liquid mainly consists of mix of propylene glycol (PG), Vegetable Glycerin (VG), nicotine and flavoring.  It is also spelled as eLiquid, e-liquid, smoke juice, juice and e-juice.


FDA:  Food and Drug Administration.  The FDA is an American government health organization responsible for protecting public health through the regulation of strict safety standards.

Flooding:  This occurs when too much e Liquid has entered the atomizer assembly.  Indicators of flooding include little to no vapor and a gurgling sound when attempting to vape.


GRAS:  Acronym created by the FDA which means “Generally Recognized As Safe.”  This terms usually pertains to e Liquid ingredients.




Juice:  Another term for e Liquid.



Leaking:  When eLiquid leaks on to the battery from the tank, cartomizer or clearomizer.  Leaking can cause your battery to be damaged and should always be avoided.

LED:  Abbreviation for Light Emitting Diode


Manual:  The term pertains to a style of battery which requires the user to use a push button to activate the heating coil.

mAh:  Abbreviation for milliampere-hour.  Mainly used when describing a battery specification.

mg:  Abbreviation for milligrams.

ml:  Abbreviation for milliliters.

Mod:  An Advanced Personal Vaporizer.  Mods usually have larger batteries and may have adjustable voltage and wattage.

Mouth to Lung (MTL): Usually done with above ohm devices.  This is the act of drawing vapor into your mouth, along with an inhalation of air, and then inhaling the vapor and air into your lungs.  MTL is the traditional inhalation method used with tobacco cigarettes.  Sub-ohm vaping usually utilizes a Direct Lung Hit (DLH).


Ni 200: Is a coil wire used in TC Mods.  The wire is over 99% pure nickel alloy and is one of the strongest metals and has excellent resistance properties.

Nicotine:  Used in liquid form in e Liquids, nicotine is a addictive parasympathomimetic alkaloid found in the nightshade family of plants and is considered a stimulant drug.  E Liquid can be purchased with our without nicotine.


Ohms: Also identified with the  symbol Ω , ohms is the measurement of resistance.  Applied to electronic cigarette atomizers, the lower the ohms, the less resistance.  This equates to a hotter coil which creates more vapor.

OLED: Acronym for Organic Light Emitting Diode.  OLED devices require no backlight and provide a higher contrast ration that an LCD.

Organic Cotton Coils (OCC): Coils made by Kangertech using unbleached organic cotton with no additives.


Pass-Through:  A battery with a micro USB connector which allows you to vape and recharge the battery at the same time.

PCC:  Acronym for Personal Charging Case.
