eCig / Electric Cigarette Glossary

Welcome to our ecig / electronic cigarette glossary we thought it would be useful to compile such a glossary as nothing available online thoroughly covered the terms we are familiar with in a single page or document. This detailed glossary is here to help our customers or any enthusiasts of the industry and explain many of the terms and technical jargon used in the electronic cigarette world helping our Vvapour visitors remain informed.

0-9 | A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z

510 Battery – The most common style of ecig battery on the market. The 510 is compatible with the majority of tanks on the market.

901 Battery – Another style/size of ecig battery.

Adapter – Often used to describe a component used to make one tank compatible with another battery which without this part would not connect.

Aqueous Glycerine / AG – Aqueous glycerine is pharmaceutical grade vegetable glycerine that has been diluted with distilled water to make it an improved consistency. VG alone is a thicker liquid and thinning it slightly it can reach the atomiser quicker.

Anodising / Anodizing – The method used to seal aluminum with a “finish”. This is achieved by submerging in electrically charged acid which changes the chemical composition of the outer layer making it harder and corrosion resistent. This method can also be used to apply colours to the metal using dye.

Atomiser or Atomizer – The component within your tank which heats up to produce vapour.

Automatic – Used to describe a style of ecig which produced vapour when you take a drag rather than via pressing a button. These are less common than button activated electronic cigarette solutions.

Battery / Batt –  This can be used to describe one of two things, a) the battery part of your ecig which often is the majority of your device, b) when referring to MODs it can refer to the traditional style battery which you remove from the ecig case.

Bridge – The part which allows the wicks to absorb your eliquid.

Cartridge – A plastic tube which usually contains some sort of filler material to hold your eLiquid. This is an alternative style to the more common cartomisers.

Cartomiser / Cartomizer / Carty – A tank which contains both the cartridge and atomiser in a single unit. Most of these are disposable however in the case of the rebuildable models only the atomizer requires replacement.

CE4 – The CE4 is one of the most common a clearomisers on the market, and there is often confusion between what a CE4 means and the difference between CE5 and CE6 since often the entire eCig package is describes as one or the other and people then believe the CE4 is a type of eCig battery and atomizer. These are available in varying lengths and battery capacity, all have the eGo thread so are compatible with most 510 batteries. Both the CE4 and CE5 hold 1.6ml of eLiquid

CE4 – The CE5 is another common clearomiser and resembles the CE4 very closely apart from having no visible wick at the top of the central column and has 4 holes in the column rather than 2 and also features a longer wick system which is not easily visible. The CE5 also features replaceable parts so you can change the atomiser head.

CE6 – The CE6 holds 2.4ml as opposed to 1.6ml other than that it is the same as the CE5.

CE7 – Another newer tank on the market the CE7 holds 2.4ml eLiquid like the CE6 however the other differences are .

Charger – Fairly self explanatory, the charger is the cable and plug used to charge up your ecig. Some are simply a usb to 510 adapter, others are actual chargers you slot batteries into.

Clearomiser or Clearomizer – A clearomiser is a type of cartomiser. Originally it began as a brand/model name for the clear CE2 cartomisers however people began to use the term to describe that style of tank. The type of cartomiser which is described as a clearomiser have a lateral/horizontal coil and wick as opposed to a axial/vertical coil. Both types are available with windows or solid  and made from plastic or metal.

Cutoff – The length the battery will remain active before the it shuts down temporarily to protect your atomiser.


Dilutents – The term used to describe the liquids which are combined with flavourings and nicotine to produce eLiquid. There are 3 dilutents, PG, VG and AG and are often mixed in different ratios.

Draw – Same as inhale, pull, or toke.

Drip Tip – One of the most talked about accessories relating to eCigs is the drip tip. This part is the mouthpiece which sits on the top of your tank. There are many different shapes, styles, colours and materials for drip tips. They also allow the user in some cases to drip their liquid directly down the drip tip, however this is ill advised if you are a novice.

Dual Coil Tanks – A tank which contains far more eLiquid. Ideal for people who vape a lot and do not want to refil their tanks as often.


eCig / e-Cig – an abbreviation of electronic cigarette.

eLiquid / e-Liquid – The liquid you use to refill your tanks. This usually contains nicotine varying in strength from 6mg to 36mg however you can get zero nicotine eLiquid. Bottle sizes also vary from 5ml up to 200ml in some cases. eLiquid is also known as juice, liquid, and is sometimes presented with or without a hyphen separator such as e-liquid.

eGo – One of the most popular and often considered the most superior of its class, the eGo battery uses a 510 battery thread but comes in varying sizes.

Electronic Cigarette – An electronic device which heats up eLiquid containing nicotine with dilutents to allow you absorb nicotine in the form of a far less harmful vapour rather than the smoke created from traditional cigarette smoking.

FDA – Stands for the Food and Drug Association which is an American Association responsible for approving consumer products of its field. While the FDA is not specific to the rest of the world and has no ruling outside the USA it is however still a great indicator as to the quality of a product.

Flooding – This is caused by having too much eLiquid on the atomiser, the rest it less vapour production since air is required for the process to operate efficiently. To avoid this, do not drip too much when using your drip tip, try not to overfill your tank and also do not repeatedly press the button as with some devices this can draw too much liquid onto the atomiser head.

Genesis / Gen / Genny – A rebuildable atomiser for the more advanced vape enthusiast. The wick uses oxidised stinless steel as opposed to a glass fibre wick available in most atomisers. These can last longer and produce more vapour.

HR / High Resistance – Used to refer to high resistance atomisers. These were created because of eCig development moving in the direction of higher voltage devices which can loose battery faster and taste burnt out when used with a low resistance or normal resistance tank. These were invented to solve those problems so are only really used with electronic cigarettes pumping out 6v or more.

Juice – another term sometimes used to describe or refer to eLiquid.

Kick – Used for two meanings. a) The feeling on the back of your throat (see: throat hit). b) The name for the add-on device used with Mechanical MODS which regulates the heat produced and the voltage.

Leaking – This occurs when your tank or cartomiser is overfilled, or if not tightened up properly. This can damage the battery so maintenance is essential. When removing the tank it is always good practice to give the connection point on the battery a wipe with a tissue to prevent the residue which does inevitably leak out a little bit from building up and breaking your ecig battery.

LED – Acronym for Light Emitting Diode.

Light Emitting Diode – Refers to a  diode that converts applied voltage to light. Often used in ecigs to indicate the battery level or the voltage level your device is set to, or even both in some cases.

Liquid – Another shorter term used to describe eLiquid.

Low Resistance / LR – Refers to an atomiser or cartomiser with a lower than usual Ohm rating. This means the charge from the battery on the element will get hotter faster and thus produce a lot more vapour.

mAh – Stands for Milli-ampere-hour which is the capacity or charge that the eCig battery will hold before it requires a recharge. Typical mAh values are 650mAh, 900mAh, 1100mAh

Manual – A manual style of ecig battery which uses a button to activate vapour production. The button is usually held for the duration of the drag the user takes. Whilst this differs from a cigarette it is the most common type of ecig and preferred by most as it does not revert to idle when leakage takes place.

mg – Refers to milligrams, the measure used to describe the amount of nicotine found in an eLiquid bottle. The usual options are  0mg, 6mg, 8mg, 12mg, 16mg, 18mg, 24mg, 30mg, and 36mg. We advice people begin with lower concentrations and work their way up if required.

Milliliters / ML  – Generally refers to the amount of liquid in an eLiquid bottle. Typical sizes are 5ml, 10ml, 15ml, 20ml and 30ml however some eLiquid manufacturers do offer larger 100 and 200ml bottles in glass or plastic bottles.

MODS – MODS usually refer to a type of eCig which is far larger and manufactured usually from metal. These eCigs often adopt removable lithium ION batteries which are the same grade used in high end torches. MODS also produce a lot more vapour and arguably a cleaner vaping experience. With that said, this term can also be applied to describe an eCig which has been modified with after market parts or DIY parts.

NRT – Acronym for Nicotine Replacement Therapy. Only Nicotine patches, gums etc are considered approved NRT’s for quitting smoking by the NHS and most other medical institutions at this time, though research is underway and may take some time.

Ohm (Ω) – The measure of electrical resistance. The lower the number the lower the resistance and therefore will heat up faster and produce more vapour in less time.

Passthrough – A wired eCig you have permanently plugged into your laptop or charger via it’s attached USB. This means there is no battery to worry about and is a good option for those who are always somewhere where they have access to power or as an additional eCig to use when your not on the move. Some people report improved and more consistent vapour and flavour using these devices.

PEG / Polyethylene Glycol – A lesser known and used dillutent used in eLiquids. PEG is said to produce more flavour and is more often used in eCigs with a cartomiser as it apparently works well that way. The specific type used for eCigs is PEG400 which makes it the correct viscosity.

Propylene Glycol /  PG – One of the core dilutants used in the majority of eLiquids on the market. Some have reported allergic reactions and those users are advised to purchase eLiquids specifically made with 100% VG or a VG/AG combination. PG produces more flavour but less vapour and a substantially more noticeable throat hit. This product has been used in medicinal inhalers and is also used in the food industry.

Pull – Same as inhale, draw, or toke.

PV – Personal Vapouriser.

Rebuildable Atomiser / Repairable Atomiser – A type of atomizer which can be rebuilt, cleaned, maintained and have its heating coil replaced over and over. They are often far more expensive however will work out cheaper then replacing the entire tank each time it burns out in the long run.

Starter Kit – Used to describe a starter package (fairly self explanatory) these often consist of one or two electronic cigarettes, a charger, a case, one or sometimes more tanks, and an eLiquid. There are many ranges of starter kit which include more items. So review our eCig Starter Kit section for more information.

Steeping – Steeping is used in the process of creating eLiquid and is often discussed in the DIY eLiquid sub culture of people making their own at home. It describes the process of leaving your eLiquid to sit for a certain length of time for the dilutents and flavouring to merge and as a result produce a stronger flavour. Different flavours have been known to take varying lengths of time to effectively bond together with their dilutents.

Throat Hit – The resistance feeling which tingles on the back of your throat as you inhale. The higher the nicotine concentration the more throat hit you will feel. Also with a diluent balance which contains more PG you also have an increased throat hit.

Toke – Same as inhale, draw, or pull.

Unprotected – Usually refers to a battery which does not have a form of protection against extreme events such as over heating, too much voltage or current. The opposite is a protected battery.

USB – Acronym for Universal Serial Bus, these are found on computers and many other devices, and the majority of eCigs use this as a charging method, a USB cable with a wall adapter or a car 12v adapter.

USB Passthrough – Same as passthrough.

Vape – The process of inhaling vapour. As an alternative to “Going for a smoke, you would use “Going for a vape”.

Vaper – An individual who uses a vapouriser or eCig.

Vape Pen / Vape Stick – Another term used to refer to an electronic cigarette which is pen like or stick like in style.

Vanity Ring – Often refers to an attractive looking metal ring to make a device compatible with a different atomiser tank.

Variable Voltage / VV  – This describes an electronic cigarette which has several voltage levels so you can choose how much vapour is produced, these are good if you want more vapour than produced by the standard single voltage eCigs or if you like it smoother at times and thicker on other occasions.

Vegetable Glycerol / Vegetable Glycerin / VG – One of the other dilutents used commonly in eLiquid VG produces a lot more vapour when you inhale and exhale however produces slightly less flavour and throat hit. Due to allergic reactions to PG this is often used in 100% concentrations to suit those who require ZERO PG.

Watts – Describes the power output or heat produced by the eCig.

Wick – Many styles of Clearomisers and tanks use poly fiber wicks to absorb the eLiquid from the tanks reservoir and deliver it directly to the atomiser head.
