306 – One of many styles of electronic cigarettes available. Many users of the 510 e-cigs are using the 306 atomizers on their batteries, as they feel it gives a better experience.
401, 402, and 403 – Also referred to as m401, m402, and m403. One of many styles of electronic cigarettes available. These are all essentially the same unit (same threading on batteries and atomizers) but with different length batteries. The 401 model is the longest in physical length and battery life of the three while the 403 is the shortest in length and battery life.
510 – Arguably the most common and popular style of electronic cigarettes available.
808 or KR808 – One of many styles of electronic cigarettes available.
901 – One of many styles of electronic cigarettes available.
Adapter – Used to allow a specific style of atomizer or cartomizer to fit onto a different style of battery. Many users prefer the vapor production of one style of atty but prefer the battery life of another style battery. This allows them to have access to both simultaneously.
Analog or Analogue – Slang term for a traditional cigarette.
Atomizer (Abbreviated as Atty) – The part of an e-cigarette that actually heats the juice to the point of vaporization.
Atty – Abbreviation for Atomizer.
Automatic – A style of electronic cigarette battery that does not have a button to activate the heating element. Rather, when the user draws on the device a switch is activated and the atomizer is activated. This style of e-cig is most like smoking a traditional cigarette.
Batt – Abbreviation for Battery.
Battery (Abbreviated as Batt) – The battery piece of an electronic cigarette is the part that provides power to the heating element. This allows the heating element to heat the Juice and produce vapor.
Bridge – A small U-shaped covering inside of the atomizer. This is used to absorb liquid and help wick it towards the heating element.
Cartridge (Abbreviated as Cart) – A plastic tube-like piece that is usually stuffed with some sort of absorbent filler material that holds the juice.
Cart – Abbreviation for Cartridge.
Carto – Abbreviation for Cartomizer.
Cartomizer (Abbreviated as Carto) – A cartridge and atomizer in a single unit. These generally are disposable, inexpensive and hold more juice than a regular cartridge/atomizer combination.
Charger – A battery charger. This is used to recharge your e-cig battery once it has been depleted.
Drip Tip – An accessory that can be used in conjunction with an atomizer or cartomizer. These have a larger opening than the original equipment and allows a user to drip Juice directly onto the atomizer. Some people use a drip tip on their Cartomizers simply for looks and/or comfort.
Dripping – A method of adding juice to the atomizer. A user will drip a few drop directly onto the bridge before vaping. Many users feel this method produces the best vapor production and taste, since there is no filler material involved with the process.
E-Cig – Abbreviation for Electronic Cigarette.
E-Juice – Also referred to as E-Liquid, Juice, or Smoke Juice. This is the liquid that is vaporized when using an electronic cigarette.
E-Liquid – Also referred to as E-Juice, Juice, or Smoke Juice. This is the liquid that is vaporized when using an electronic cigarette.
ECF – Abbreviation for E-Cigarette-Forum.
eCigology – The science of e-cigs. Also the greatest e-cig blog of all time.
eGo – A style of electronic cigarette that utilizes the 510 threads and allows one to use 510 components but with a much larger battery. Many people feel this is one of the superior models of e-cigs that are available.
Electronic Cigarette (Abbreviated as E-Cig) – A device that heats up a liquid solution consisting of nicotine, propylene glycol and/or vegetable glycol, and flavorings to a point where it actually turns into a vapor which can be inhaled.

FDA – Abbreviation for the (United States) Food and Drug Administration.
Filler Material (Abbreviated as Filler) – Material placed inside of a Cartridge that is absorbent. It is used to help keep the juice inside of the cartridge and deliver it to the atomizer at an optimal pace (so as to not flood the device). Most cartridges come with PolyFill being used as the Filler Material, but there are many modifications available that may help enhance your e-cig experience (such as the Pyramid Tea Bag mod or Blue Foam mod – check our Modifications section for more information).
Flooding – Something that can occur when too much Juice is applied to the atomizer. Since atomizers require some air to properly vaporize Liquid, adding too much Juice to an atomizer will cause a decrease in Vapor Production and flavor.
Food and Drug Administration (Abbreviated as FDA) – An administrative branch of the United States government that oversees rules and regulations pertaining to the safety of food and drug products sold in the USA. There is currently a very controversial lawsuit involving the FDA and the importation and distribution of electronic cigarettes.
Juice – Also referred to as E-Liquid, E-Juice, or Smoke Juice. This is the liquid that is vaporized when using an electronic cigarette.
Leaking – This can happen when too much Juice is added to an atomizer or cartomizer. Juice can leak out of the bottom of the heating element and onto the battery, which in some cases can cause damage to the device (as is the case with Automatic Batteries).
LED – Abbreviation for Light Emitting Diode.
Light Emitting Diode (Abbreviated as LED) – A diode that converts applied voltage to light. These are commonly used in electronic cigarette devices to indicate that the device is actively being used.
Liquid – Also referred to as E-Liquid, E-Juice, Smoke Juice, or Juice. This is the liquid that is vaporized when using an electronic cigarette.
Low Resistance (Abbreviated as LR) – An atomizer or cartomizer with a lower Ohm rating than the standard equipment. This generally causes the heating element to get hotter faster and produces vapor more quickly. In many cases it produces more vapor than an atty or carto that has a standard resistance rating.
LR – Abbreviation for Low Resistance.
m401, m402, and m403 – Also referred to as 401, 402, and 403. One of many styles of electronic cigarettes available. These are all essentially the same unit (same threading on batteries and atomizers) but with different length batteries. The m401 model is the longest in physical length and battery life of the three while the m403 is the shortest in length and battery life.
Manual – A style of electronic cigarette battery that has a button (usually on the top or side of the battery) that activates the heating element. When the user wishes to use the device, the button must first be depressed in order to produce vapor from the atomizer. This style of e-cig is less like a traditional cigarette than the Automatic, but is preferred by many due to the fact that it is sealed and can not be adversely affected by Leaking.
mg – Abbreviation for Milligrams.
Milligrams (Abbreviated as mg) – The amount of nicotine found in a Juice. Typical levels include 0mg, 6mg, 8mg, 12mg, 16mg, 18mg, 24mg, 30mg, 36mg and 48mg. Generally speaking, a medium level of nicotine is around 18mg. Those who use Juice with a higher nicotine content than that are generally people who were heavy smokers or have been vaping for quite some time.
Milliliters (Abbreviated as mL) – The amount of Juice in a given container.
Mini – One of many styles of electronic cigarettes available. These generally are about the same size as a traditional cigarette and have the shortest battery life of any style.
mL – Abbreviation for Milliliters.
Mod – Dual usage – Can be used to describe modifications to a device or accessory (such as getting more vapor production out of your cartridges) or a design variation of a commonly manufactured electronic cigarette. In the latter context, mods typically use larger rechargeable Lithium Ion batteries and allow the user longer battery life and increased vapor production but at the cost of the device looking like a traditional cigarette.
Many mods will also allow the user to increase or decrease the voltage of their device to achieve optimal performance.
Ohm – A measure of electrical resistance. A lower number indicates lower resistance and therefore faster heating.
Passthrough – A device that plugs directly into the USB port of a computer or charger and allows the user to vape without having to worry about battery life. Some users report better vapor production and/or flavor while using a Passthrough compared to their regular batteries.
PCC – Abbreviation for Personal Charging Case.
Pen Style – One of many styles of electronic cigarettes available. Slightly resembles a ball point pen in appearance.
Personal Charging Case – A portable charger that can be taken with a user on the go to charge electronic cigarette batteries when away from a power outlet. Particularly useful when using an e-cig that has less than a 2 hour battery life per charge. Take a look at this post for battery life information for many common e-cig batteries.
Personal Vaporizor (Abbreviated as PV) – Another name for an Electronic Cigarette. Usually used in reference to the more untraditional style e-cigs (also known as Mods).
PG – Abbreviation for Propylene Glycol.
Propylene Glycol (Abbreviated as PG) – An ingredient found in many brands of E-Juice. Some users have reported an allergic reaction to it and must therefore use 100% VG Juice instead. This is one of the ingredients used that when heated will produce vapor that can be inhaled. Typically, PG produces less vapor than it’s VG counterpart but provides more flavor and Throat Hit. This substance has been used as a primary ingredient in medical inhalers for years.
PV – Abbreviation for Personal Vaporizor.
Smoke Juice – Also referred to as E-Liquid, Liquid, Juice, or E-Juice. This is the liquid that is vaporized when using an electronic cigarette.
Smokeless Cigarette – A term used to refer to an electronic cigarette. This term is used commonly due to the fact that no actual smoke is inhaled or exhaled while using an e-cig.
Starter Kit – A kit that includes basic e-cigarette equipment. Typically includes everything needed to begin vaping. Most starter kits come with 1 or more atomizers, 1 or more batteries, a charger and 5 cartridges pre-filled with Juice.
TH – Abbreviation for Throat Hit.
Throat Hit (Abbreviated as TH) – The tingling feeling one feels in the back of the throat when vaporizing juice that contains nicotine. Typically, since nicotine is a large contributing factor in throat hit, when a juice that contains zero nicotine is vaporized, there is no throat hit.
Vape – The action of “smoking” an electronic cigarette. Since e-cigs actually produce vapor (rather than smoke) people refer to this as “Vaping”.
Vapor Cigarette – A term used to refer to an electronic cigarette. This term is used commonly due to the water vapor that is exhaled when using an e-cig.
Vapor Production – Typically associated with Juices. Indicates how much vapor is produced using an average inhale of an e-cigarette.
Vegetable Glycerol or Vegetable Glycerin (Abbreviated as VG) – An ingredient found in many brands of E-Juice. This is one of the ingredients used that when heated will produce vapor that can be inhaled. Typically, VG produces more vapor than it’s PG counterpart but provides less flavor and Throat Hit. Some users who are allergic to Propylene Glycol must use 100% VG Juices.
VG – Abbreviation for Vegetable Glycerol or Vegetable Glycerin.
Wick – A narrow piece of poly string that is inside of many styles of atomizers that allows easier delivery of Juice to the heating element.

We are starting a vape shop in Vancouver, WA and are going to create a glossary of terms. You have provided much of the basic terminology I had started to gather. Would you be opposed to me using some of this for my write up I am doing. I intend to expand on it and provide pictures for a lot of it. But some of your definitions are far better then what I came up with. Our store is called Fatboy Vapors.

There is a bit of misinformation in one of the entries above, an all too common mistake which I can find even on ProVape’s homepage: the idea that e-cigs produce “water vapor.” However, electronic cigarettes do not produce water vapor! It states above:
“Vapor Cigarette – A term used to refer to an electronic cigarette. This term is used commonly due to the water vapor that is exhaled when using an e-cig.”
Except for negligible quantities of water present in some flavorings and perhaps an infinitesimal amount of condensed humidity in an atomizer, there is no H2O in the e-liquid and therefore any water in the *exhaled* vapor will be from one’s lungs and not produced by the e-cig itself. I vape every day and can assure you that the vapor is simply gaseous PG and/or VG.
There is currently much debate about electronic cigarettes worldwide; the more factual information available the better. Thanks for putting up such a site.

Can you double check that VG has been used in inhalers in your glossary, rather than PG? Thanks!

Thanks for the heads up Connie! You’re right on that one… I guess in putting all this info together I kind of had a brain fart. Corrected 🙂
