Glossary

Glossary of E-Cigarette Terms

 

510:

This refers to the screw thread connection and is the most commonly used thread pattern on an e-cigarette battery or vaping accessory connection.  It also refers to the compatibility of components.

Adjustable Airflow:

This allows vapers to adjust the airflow into the tank via either a screw or dial to customise the amount of vapour and flavour.

Atomizer Head:

A unit that houses the heating coils and wicking material. Atomizer heads are consumable products that require replacement usually between 4-6 weeks depending on the device and individual use.

BDC - Bottom Dual Coil:

A BDC is an atomizer head that has two coils mounted in the base of a tank. The base position means that the heating coils are permanently immersed in e-liquid to prevent overheating the coils. The dual coil refers to two coils in parallel which diffuse the load evenly to deliver high performance and durability.

Burning:

Burning occurs if the coil gets too hot and there is insufficient e-liquid in the device. In certain circumstances the wicking material burns which can result in an acrid taste that is unpalatable. Once a coil is burnt it is unlikely to recover normal performance and usually needs replacing.

Cartomizer:

Used in the original Odyssey tank, a cartomizer contains absorbent wadding, which is soaked with e-liquid.

Dry Hit:

A dry hit occurs if the wicking material is too dry due to lack of e-liquid in the e-cigarette.

E-cig / E-cigarette:

These are terms that are commonly used to refer to electronic cigarettes.

E-Liquid:

E-liquid is the fluid which is used to produce vapour and flavour on inhalation of an e-cigarette. They can be flavoured or unflavoured and are available in different nicotine strengths.  E-liquids are also offered as pre-mixed fluids which can be used straight from the bottle or vapers can mix their own for a more personalised vape.

Ohm (Ω):

The ohm is the SI unit (International System of Units) of electrical resistance.  Ohms Law is named after its creator, the German physicist Georg Simon Ohm.  Atomizer heads have a varying range of resistance of the heating coil which is measured as a numerical value. E.g. 1.8ohm.

OLED:

Organic Light-Emitting Diode - displays vaping information on a digital screen.

Plinth:

A plinth is decorative collar of metal that is used on the outer thread of an e-cigarette battery to enhance the appearance of the e-cigarette and add stability to a flat-based tank.

RCS (Replacement Coil System):

RCS refers to an atomizer head which can be replaced when the coil reaches the end of its natural life.

Resistance:

See Ohms Law above.

Tank:

The tank usually sits on top of the e-cigarette and connects to the battery, though some devices now have integrated tanks. This part of the e-cig houses the atomizer and e-liquid.

Temperature Control (TC):

TC devices heat the coils more quickly and maintain the temperature instead of ‘spiking’ and provide a more consistent performance. TC also prevents dry hits and coil damage. 

Vaping:

The inhalation and exhalation of vapour produced by an e-cigarette is referred to as vaping.

VV - Variable Voltage / VW - Variable Wattage:

There are two common output measurements that devices refer to, Variable Voltage (VV) and Variable Wattage (VW). 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.

Wick:

Wicks are made from a variety of materials but the most commonly used is Silica rope. The wick is housed in the atomizer and absorbs the e-liquid when the coil is heated to produce vapour.
