Glossary of E-cigarette Terms
Either a screw or dial that adjusts the airflow into a tank as the user inhales affecting both the amount of vapor and flavor.
AG - Aqueous Glycerine
AG is pharmaceutical grade VG (Vegetable Glycerine) which has been thinned using deionized water to make it a similar viscosity to PG (Propylene Glycol) and is used as a diluent when mixing your own liquid. AG produces more vapor than PG and adds a little sweetness to the mix.
A term vapers give to tradition tobacco cigarettes.
A generic term given to the part of the e-cig that heats the e-liquid and turns it into a vapor.
Unit that houses the heating coils and wicking material. Consumable that requires replacement between 1 and 6 weeks depending on the device.
American Wire Gauge is a standardized wire gauge used in North America, whereas in Europe the diameter of the wire is expressed in millimeters. Resistance wire is used to make heating coils.
A battery supplies power to the atomizer and can be an integrated battery unit, where the battery is built in or a removable battery that can be removed from the e-cigarette to recharge or replace it.
BDC - Bottom Dual Coil
This atomizer head has two coils mounted in the base of a tank. The position means that the heating coils are permanently immersed in e-liquid, which prevents overheating the coils. The dual coil refers to two coils in parallel spreading the load delivering high performance and durability.
Occurs if the coil gets too hot without enough e-liquid. In certain circumstances it can burn the wicking material delivering an acrid taste that is unpalatable. Once a coil is burnt it is unlikely to recover normal performance and usually needs replacing.
The mouthpiece part that contains fibre that holds the e-liquid, usually found in cig-a-like devices.
This is a coil of wire that acts as a heating element and is located in the Atomizer Head.
Is usually the positive feed from the battery, it can be fixed or sprung and makes contact with the positive pin of the atomizer.
DDA – Direct Drip Atomizer
Is an atomizer that has no e-liquid tank and requires regular topping up with e-liquid through a Drip Tip.
Diluents are liquids that are used to dilute your e-liquid mixes. The main diluents are PG and VG and mixed in different ratios can alter the vaping characteristics of the e-liquid.
Is a mouthpiece with a wide bore through which you can drop e-liquid to refresh the coil of a Direct Drip Atomizer.
Occurs if the wicking material is dry or has dried out due to lack of e-liquid.
E-cig / E-cigarette
Words often used to abbreviate electronic cigarette.
The term used to describe the fluid used within electronic cigarettes. It can come with or without nicotine, in many strengths and flavors and either pre-mixed or mix your own.
Li-ion Cobalt Round cell, refers to the chemical make-up of a battery. ICR’s can have high capacity rating (mAh) but deliver a lower current than an IMR. ICR batteries are recommended for atomizers with a resistance of 1.0Ω or above.
Li-ion Manganese Round cell, refers to the chemical make-up of a battery. IMR’s generally have a lower capacity rating (mAh) but deliver a higher current than an ICR. IMR batteries are recommended for atomizers with a resistance below 1.0Ω.
Japanese cotton is a natural wicking material that uses no chemicals or bleaches in its production and has good e-liquid retention properties but can burn at high temperatures.
Kanthal (FeCrAl) is a wire alloy containing iron, chrome and aluminium. It is used to make heating coils.
Milliamp is a unit used to measure current and is equal to one thousandth of an Amp. 1000mA = 1A. This applies to the battery charging current, the higher the milliamps the faster a battery will charge. The charging rate should never be greater than the mAh rating of the battery.
A unit for measuring electric power over time. mAh is commonly used to describe the total amount of energy a battery can store at one time.
Most modern electronic cigarettes have a Micro USB port for charging the battery.
Mixing can refer to blending one or more flavored e-liquids with each other. Advanced mixing can involve mixing a solution of diluent with concentrated flavoring and a solution that may or may not contain nicotine.
A “Mod” originally meant “Modified” and referred to hand made components/devices that used converted household items such as flashlights or lozenge tins. Mechanical mods have no electronic switches, regulators or chips and rely on mechanical connections to operate.
A milliliter (that is milli and liter put together) is a very small amount of liquid. There are approx. 20 drops to one ml. With e-cigarettes it is used to indicate the capacity of the tank and selling volume of e-liquid.
Nickel wire is a low resistance wire used to make heating coils and can be used with VT (Variable Temperature) devices. Pure nickel is used because there is a linear relationship between resistance and temperature. As the coil heats, the resistance changes and the algorithm built into the processing chip of the electronic cigarette can determine the temperature from the resistance it is measuring.
Nichrome is a popular resistance wire used to make heating coils, it is a nickel/chrome alloy.
The ohm is the SI unit of electrical resistance and is named for Georg Simon Ohm, the German physicist who created Ohms Law. On atomizer heads it indicates the resistance measure of the heating coil as a numerical value. E.g. 1.8ohm.
PG (Propylene Glycol) is pharmaceutical grade and is used as a diluent when mixing your own liquid. PG produces less vapor than VG and adds clarity to flavors.
A decorative collar of metal that is used on the outer thread of an e-cigarette battery to streamline the aesthetic appearance of the unit and add stability to a flat-based tank.
Person Vaporizer, another name for an electronic cigarette.
RCS - Replacement Coil System
Refers to the atomizer head being replaced when the coil reaches the end of its natural life.
Silica Rope Wick
Silica rope can stand very high temperatures that can be used instead of Japanese Cotton. The wicking properties of silica are not as efficient at Japanese Cotton.
Refers to heating coils with an electrical resistance of less than 1.0Ω.
Top of an e-cigarette which connects to the battery, houses the atomizer and e-liquid and has either a removable or fitted mouthpiece on top.
Throat Hit or Throat Kick is the sensation of nicotine at the back of the throat.
Titanium wire is a low resistance wire used to make heating coils and can be used with VT (Variable Temperature) devices. Pure titanium is used because there is a linear relationship between resistance and temperature. As the coil heats, the resistance changes and the algorithm built into the processing chip of the electronic cigarette can determine the temperature from the resistance it is measuring.
Inhale and exhale the vapor produced by an electronic cigarette or similar device.
Totally Wickeds’ Vegetable Glycerine is pharmaceutical grade VG (Vegetable Glycerine). It is used as a diluent when mixing your own liquid. VG produces more vapor than PG and adds a little sweetness to the mix.
VV / VW / VT / Variable Voltage / Variable Wattage / Variable Temperature
These common terms refer to output measurements that vaping devices refer to, Variable Voltage (VV), Variable Wattage (VW) and Variable Temperature (VT). Variable Voltage refers to electromotive force being pushed through the atomizer whereas Variable Wattage refers to the power produced by that force. Put simply a Variable Wattage device detects the atomizer resistance and selects the correct voltage to deliver the desired output whereas a Variable Voltage device delivers the selected output irrespective of the atomizer resistance. Variable Temperature controlled devices enable you to pre-set a maximum temperature in celcius or farenheight that the atomizer coil will be able to reach.
Normally made of Silica rope, which is fire retardant while being efficient in wicking the e-liquid to the atomizer coil, or cotton which provides full flavor and vapor production.
This refers to the screw thread cut and is the most common thread pattern used on e-cigarettes which aids cross compatibility of components. It is also used to refer to the compatibility of mouthpieces and the connection at the top of the tank.
Available in a variety of colors and styles. Tanks with a 510 fitting mouthpiece have the ability to swap with another 510 mouthpiece allowing for personalization and customization.
