Words Starting with A

Acetyl Propionyl (2,3-Pentanedione): An organic compound found in some flavorings. This diketone is used to enhance some flavors and has an odor described as "buttery, cheesy, sweet, nutty, fruity, creamy, caramel". Studies indicate that the inhalation of Acetyl Propionyl may cause similar health effects as Diacetyl and should be avoided at all costs. 

Advanced Personal Vaporizer (APV): An advanced e-cigarette that often has larger battery capacity or advanced features like digital display, adjustable power output, or other features making it advanced.

Airflow Control Valve (AFC Valve): An adjustable portion of the atomizer or clearomizer that allows the vaper to control his or her airflow on the fly.

All Day Vape (ADV): Refers to an e-liquid that you personally favor over any others that you have or have tried. The e-liquid that you can use throughout the day, day after day, that never gets old.

American E-Liquid Manufacturing Standards Association (AEMSA): The first and only manufacturers’ trade association completely dedicated to creating responsible and sustainable standards for the safe manufacturing of “e-liquids” used in e-vapor products (aka electronic cigarettes). AEMSA is an all-volunteer organization, formed by American manufacturers of e-liquids, to promote safety and responsibility through self-regulation.

American Wire Gauge (AWG): The standardized American wire gauge system used to describe the diameter of a conductive wire.

Amperage (Amps): A term used to describe the number of electrons moving past a fixed point in a conductor in one second. Current is measured in units called amperes or amps.

Analog: The word that vapers use to describe a traditional tobacco cigarette.

Atomizer (aka Atty): The portion of an electronic cigarette responsible for heating and vaporizing the e-liquid. Atomizers (in the traditional sense) were much more common during the early stages of vaping. Since vaping has become increasingly popular and technology has advanced, regular atomizers are rarely used with refillable devices.

Automatic: Refers to an e-cigarette that activates with a reed or piezo switch rather than a pushbutton. The automatic style e-cigarette was one of the original designs because it closely mimicked the typical use of a traditional cigarette. Automatic e-cigarettes were quickly abandoned by more serious vapers because they often activated in vaper’s pockets and the hit was not always consistent.

Automatic Shut-off: Refers to the duration of time in which the e-cigarette will allow the user to activate the device in each puff. Many e-cigarettes have automatic shut-off intervals of 10 seconds to prevent dry burning your atomizer or clearomizer if you accidentally press the button while the device is in your pocket.

Words Starting with B

Battery: The portion of the e-cigarette or vaporizer that supplies power to the remainder of the assembly. The term “battery” can often be confusing to new vapers, not because it’s hard to understand, but because there are so many varieties available and each type serves its own purpose.

  • “Cig-A-Like” Battery: Refers to e-cigarette batteries that closely resemble traditional cigarettes in size and sometimes in appearance. These batteries are often available primarily in automatic (puff activated) versions but some manufacturers do offer manual (push button activated) versions.
  • “Pen-Style” Battery: Refers to e-cigarette batteries that may be close to the size of a traditional cigarette but are typically a bit larger in size. These batteries are usually available in both automatic (puff activated) and manual (push button activated) versions.
  • “eGo-Style” Battery: Refers to e-cigarette batteries that feature an eGo style thread (510 thread with outside thread for cones, covers, etc.) and are closer in size to that of a small cigar. These batteries are primarily available in manual (push button activated) versions.
  • Changeable Battery: Typically indicates that the battery is a removable type of battery and is typically used in APVs, mods, mechanical, and other (larger) devices. Changeable batteries may include lithium type batteries ranging in size from 18350 to as large as 26650.
  • Built-In Battery: Normally when you see an APV (advanced personal vaporizer) or box mod that includes a built-in battery, these batteries typically are not user serviceable (changeable) but may provide far higher capacities than those of changeable batteries due to their lithium polymer (LiPo) chemistry.

Battery Vents (Vented, Vented Cap): An opening in the personal vaporizer that allows the internal battery to vent in the event of a battery failure.

Big Pharma (BP): Vaper’s slang for commercial pharmaceutical manufacturers.

Big Tobacco (BT): Vaper’s slang for commercial tobacco companies and producers.

Bottom Coil (BCC): A clearomizer or replacement coil that has a coil that resides at the bottom of the tank instead of at the top.

Bottom Dual Coil (BDC): A clearomizer or replacement coil that has two coils that reside at the bottom of the tank.

Bottom Vertical Coil (BVC): A clearomizer or replacement coil that has a single bottom coil that is oriented vertically rather than horizontally. Vertical coils offer less airflow resistance and are said to produce more pronounced flavor compared to their counterparts (BCC and BDC coils).

Box Mod: An e-cigarette that is rectangular in shape and typically features a larger battery capacity and may also include advanced functionality such as safety features or digital display, etc. to improve the control over the device.

Brick and Mortar (B&M): A retail establishment that sells products to consumers in a face-to-face transaction.

Bridgeless Atomizer: An atomizer that has either had its wicking bridge removed or has been manufactured without a wicking bridge to allow e-liquid to be dripped directly onto the coil. The bridgeless atomizer was the “original” dripper’s dream because it was simple to use and required little effort to clean.

Build Deck: The area in which coils are attached to the positive and negative posts of rebuildable atomizers. Build decks are often raised to help prevent excess e-liquid in the juice well from coming in contact with the positive and negative posts.

Words Starting With C

Car Adapter: 12V adapter that plugs into your vehicle’s cigarette lighter. Typical car adapters are those that convert your vehicle’s 12V power to a 5V USB port.

Cartomizer (aka Carto): A cylindrical tube that houses a heating coil surrounded by absorbent cotton or polyester wicking material that simplified the original 3-piece e-cigarette design (battery / atomizer / cartridge) into a 2-piece design (battery / cartomizer). Think of the cartomizer as the heating portion that simplified the e-cigarette design and led to many more technological advances in heating elements.

Cartridge (aka Cart): A cartridge is a liquid holding reservoir with an absorbent material that usually comes into direct contact with the bridge of an atomizer allowing the liquid to wick onto the coil of the atomizer.

Charger: A device used to recharge a vaporizer’s battery.

Clearomizer (aka Clearo): Very similar to a cartomizer in regards to the combination of atomizer and cartridge except that a clearomizer does not contain any absorbent material to hold the liquid in the reservoir, rather, the coil has silica or cotton wicks that serve as the wicking material for the liquid to make its way onto the heating coil.

  • Bottom Coil Clearomizer (BCC): A clearomizer that has a coil that resides at the bottom of the tank instead of at the top.
  • Bottom Dual Coil Clearomizer (BDC): A clearomizer that has two coils that reside at the bottom of the tank.
  • Bottom Vertical Coil Clearomizer (BVC): A clearomizer or replacement coil that has a single bottom coil that is oriented vertically rather than horizontally. Vertical coils offer less airflow resistance and are said to produce more pronounced flavor compared to their counterparts (BCC and BDC coils).

Clouds: Refers to the vapor exhaled from your vaporizer. When someone says “You’re blowing some massive clouds!” (followed by “bruh” if you are in California), it typically means that you are producing a large volume of vapor from your personal vaporizer.

Coil: The last element in the equation before e-liquid is turned into vapor. Constructed of coiled resistance wire that comes in a variety of materials. The most common material used in the construction of coils is a metal alloy called Kanthal A1, however, many other types may be available depending on the application.

Coil Tool (jig, winder, etc.): An instrument used to assist with the coil winding and rebuilding of rebuildable atomizers.

Connection: The point in which the threads of the atomizer connect to the threads on the battery.

Words Starting With D

Darwin: The first advanced personal vaporizer to utilize wattage based user control. The Darwin was introduced in 2010 and was manufactured by Evolv Vapor LLC. The Darwin was “retired” in 2012 and was one of the most highly regarded vaporizers in the market.

De-wick: To remove wicking material from an atomizer.

Diacetyl: A diketone compound that can be found in some flavorings. Diacetyl should be avoided like the plague because inhalation of Diacetyl at certain levels is known to cause respiratory issues like illness and in some cases, an incurable respiratory disease that is known as Bronchiolitis Obliterans (or "Popcorn Lung").

DNA: The name of a series of highly advanced microprocessor controlled circuits designed for vaping, created by Evolv Vapor LLC. The DNA series adds a variety of safety features for vaping and set the foundation for the use of wattage based adjustments in personal vaporizers.

Do It Yourself (DIY): Often refers to the act of making your own e-liquid at home. We DO NOT recommend doing this as the components that go into e-liquid can be very dangerous to work with and should only be used by experienced lab technicians.

Dripping: Directly dripping e-liquid onto the heating coils of the atomization portion of an electronic cigarette.

Dry Burn: Heating coils to a point that they are glowing with the intent of cleaning any excess e-liquid in preparation for the next flavor. We do not recommend dry burning your coils because the metal will oxidize and the health effects of this oxidation are not well known.

Dry Hit: Perhaps any vapers most feared experience with vaping. A dry hit occurs when the atomizer is not primed properly or is running dry and exhibits an excruciatingly disgusting flavor. When you get a dry hit on a clearomizer or replaceable coil type tank, you’re best off to replace the coil because it’s very difficult to ever get the foul taste to go away.

Words Starting With E

Electronic Cigarette (E-cigarette, E-cig): An emerging device that serves as an alternative to smoking. An e-cigarette relies on the atomization and vaporization of e-liquid that creates vapor that mimics the appearance of smoke.

E-liquid (commonly referred to as E-juice, Vape Liquid): The liquid portion of the electronic cigarette that is used to create the vapor that is inhaled when the electronic cigarette is in use.

Words Starting With F

Flavor Production: The perception of flavor when taking a puff. There is usually a tradeoff between flavor production and vapor production. You can have large amounts of both, but typically one is heavier sided than the other.

Flooded (flood, flooding): Overly saturated wick or atomizer coil resulting in very wet puffs or poor performance.

Words Starting with I

ICR Battery: Refers to lithium cobalt oxide battery chemistry.

IMR Battery: Refers to lithium manganese oxide battery chemistry.

INR Battery: Refers to lithium manganese nickel battery chemistry.

Mod: Modified personal vaporizer, some vapers refer to any larger sized vaporizer as a mod.

Mouth-To-Lung: The act of inhaling into the user’s mouth before inhaling into the lungs. Flavor chasers may prefer this type of hit because it allows the flavor to “rest” in the user’s mouth prior to inhalation. When vaping mouth-to-lung, users typically get a slightly stronger throat hit compared to lung hit(s).

Words Starting with N

Newbie (aka Noob, Newb): Beginner, someone who is new to the use of electronic cigarettes.

Nicotine (NIC): The nicotine that is found in e-liquid products (if ordered in any strength higher than 0mg/ml).

Words Starting with P

Personal Vaporizer (PV): An electronic cigarette

Propylene Glycol (PG): A colorless, almost odorless, slightly sweet compound that is used as a base ingredient in e-liquid. It is used primarily as a flavor carrier and diluent for other ingredients. This ingredient has a viscosity similar to water. This ingredient provides an increased throat hit and contributes to overall flavor consistency.

Words Starting with R

Rebuildable Atomizer: Refers to any atomizer that features the ability for the user to build his or her own coils and attach them to the positive and negative pin(s) on the build deck.

  • RBA: Refers to a rebuildable atomizer.
  • RDA: Refers to a rebuildable dripping atomizer.
  • RDTA: Refers to a rebuildable dripping tank atomizer.
  • RTA: Refers to a rebuildable tank atomizer.

Words Starting with S

Steeping: The process of “resting” your e-liquid in order to give the flavors and base ingredients more time to blend and / or soften. There are a lot of myths around steeping and this process is considered somewhat experimental.

Strength: Refers to the mg strength of nicotine content in an e-liquid.

Words Starting with T

Throat Hit (TH): The harsh feeling in the back of your throat that you get when you inhale from your e-cigarette.

Traditional Cigarette: Tobacco Cigarette

Tube Mod: A device that is cylindrical in shape and features a replaceable battery. There are multiple versions of tube mods, including (but not limited to): Mechanical Mods, Advanced Personal Vaporizers, replaceable battery type eGo style batteries.

Words Starting with V

Vape: The act of using an electronic cigarette. (Similar to the term “Smoking” when referring to a tobacco cigarette)

Vape Shop: A retail establishment that sells products to consumers in a face-to-face transaction.

Vaper’s Tongue: When the tongue gets acquainted with a flavor and the taste becomes unperceivable. The most common fix for vaper’s tongue is to change up your flavor rotation and try something new.

Vapor: The visible portion emitted from an electronic cigarette when in use.

Vapor Bar: A sampling bar found mostly in Brick and Mortar stores that allow a consumer to sample liquids prior to purchasing them.

Vapor Production: The amount of vapor that is produced with a personal vaporizer.

Variable Voltage (VV): Refers to the personal vaporizer’s ability for the user to adjust the output voltage settings of the device. The capability to alter the device’s output voltage allows the user to “fine-tune” the performance and experience they get with the personal vaporizer.

Variable Wattage (VW): Pioneered by Evolv Vapor, variable wattage refers to the personal vaporizer’s ability for the user to adjust the output wattage settings of the device. Wattage adjustment differs from voltage adjustment because the device is constantly reading the atomizer’s resistance level to ensure that the output remains consistent with the set level.

Vegetable Glycerin (VG, Glycerol, Glycerin): A colorless, odorless, viscous compound that is used as a base ingredient in e-liquid. It is used primarily as a diluent for other ingredients. This is the highest viscosity component found in e-liquid, contributing to increased vapor production when vaporized.
