Vaping Glossary


Adult nicotine consumers new to vaping often face new terminology, technology and techniques. Don’t know an atomiser from a clearomiser? Confused about the differences between propylene glycol and vegetable glycerine? This vaping glossary is here to help!

     1. Aerosol The technical term for the cloud of vapour that is inhaled from a vape device and exhaled by the consumer.
     2. Airflow The rate, speed and pressure at which air flows from your vape device when you inhale.
     3.  Amp A unit of electrical current (ampere). The number of amps tells vapers how powerful a battery is; the higher the amps, the higher the battery power.  
     4.  APV (advanced personal vaporiser) A name for the most sophisticated vaping devices, which usually have adjustable settings, letting consumers adjust airflow and power (wattage and voltage) for more bespoke vaping. 
      5. Atomiser The heart of any vaping device; the part which converts e-liquid into vapour droplets, ready to be inhaled. 
     6.Automatic A name for vape devices that don’t have an on/off button.
     7.Battery The battery of a vape device provides the electrical power needed to create heat.
    8. Battery cutoff   A safety feature that causes the device battery to cut off after a time, preventing the device from being left on for too long and stopping the e-liquid from overheating.
   9. Box mod (box modular) A kind of APV (advanced personal vapouriser) where the device is rectangular box-shaped, with a mouthpiece sticking out of the top.
   10. Cartomiser A single disposable cartridge which contains an atomiser and e-liquid. 
   11. Cig-a-like This specific e-cigarette style resembles a traditional cigarette with a white body and brown end.
   12. Clearomiser The transparent tank that holds e-liquid in an open-system vape device; clearomisers can hold 2ml of e-liquid or less under UK law.
   13. Coil and wick

Most vape devices use a coil and wick system to heat e-liquid.

This heating method is similar to the mechanism in an oil lamp: a heating coil wrapped around a wick made of cotton or silica.

When the device is activated, the coil and wick heat up to vaporise e-liquid, which then partially re-condenses as a mixture of gas and liquid droplets – the vapour you inhale.

   14. Concentration In vaping, concentration describes how much nicotine is in an e-liquid.
   15. Custom mod (custom model) Usually refers to a vape device model built by a consumer rather than a factory model.
   16. Dripping

‘Dripping’ e-liquid directly onto the heating element of a vape atomiser instead of feeding it in through the clearomiser.

We do not recommend dripping with Vuse devices. Please use your device correctly by referring to the user manual.

   17. Dry hit

This happens when a vape runs out of e-liquid; the wick is dry and can burn, making the vapour taste unpleasant.

If you’re using a closed system device, change the flavour cartridge to correct this.

If using an open system vape, refill the clearomiser with e-liquid or change the atomiser and wick.

A dry hit can also be caused by having the airflow or power settings too high – try lowering both.

   18. DTL (Direct-to-lung)

An inhalation technique where vapour is drawn directly into the lungs without holding it in the mouth (like taking a deep breath).

   19. e-liquid

The liquids you put into your device to vape. We make our eLiquids using propylene glycol (PG) and vegetable glycerine (VG) in various flavours with and without nicotine.

   20. Generation

In the world of vaping devices, like many tech products, ‘generation’ is roughly the same as the word ‘version’, used when referring to a particular product (vaping device) or component.

   21. ISO 9001:2008

This line of numbers probably doesn’t mean much to most people, but here at Vuse, it means a great deal.

ISO 9001:2008 is a strict specification of quality management standards from the International Organization for Standardization (ISO), a network of national standards institutes from 163 countries.

We proactively maintain ISO 9001:2008 for our quality management business system.

   22. LED

The light on a vape device; the LED usually glows when in use.

   23. Lithium-ion

The type of battery used in all Vuse devices.

   24. mAh

An acronym in the description of batteries that means ‘milliamp hour’, a measure of battery charge capacity.

If two batteries have identical voltage, then the one with a larger mAh will last longer.

   25. Milliampere

One-thousandth of an ampere – a measure of the amount of electrical charge flowing past a circuit point at a specific time.

   26. MTL (mouth to lung)

An inhalation technique where vapour is drawn into the mouth and held for a few seconds before being passed into the lungs.

This vaping method is often compared to smoking a traditional cigarette.

   27. Nicotine

Nicotine occurs naturally in several varieties of plants but is found in the highest quantities in the tobacco plant.

   28. Nicotine salts

Found mainly in the leaves of the tobacco plant, where nicotine exists in a salt form.

The nicotine salts in tobacco have been recreated in e-liquid by adding an ingredient which reacts with nicotine to form a nicotine salt.

In ‘salt’ form (protonated nicotine), nicotine is more stable than in other e-liquids.

   29. No-nic

A type of e-liquid that doesn’t contain any nicotine.

   30. Ohms

A unit of electrical resistance named after German physicist Georg Simon Ohm. In vaping, measurements of resistance usually relate to the heating coil in the atomiser. The lower the resistance, the hotter the coil can get.

   31. Over-voltage and over-heating controls 

Vuse devices are designed for safe charging, with over-voltage protection and a timed cutoff system.

Please don’t use alternative or unbranded charging cables or AC adaptors, as they may not be compatible with Vuse devices and may even be counterfeit.

   32. Propylene glycol (PG) 

One of two primary ingredients in e-liquid; colourless, clear and nearly odourless. 

   33. Puff activation

Some vapes are activated by pressing the power button; others are ‘puff activated’, which means they’re activated when consumers take a draw. 

   34. Resistance

How much electrical current the heating coil of a vaping atomiser allows, measured in ohms. The lower the resistance, the hotter the coil can get.

   35. Temperature control

The technology that controls the temperature inside a vape device for safety reasons and to produce a better vape.

   36. Throat hit

The feeling when the vapour hits the back of your throat.

   37. Tube mod (tube modular)

A kind of APV (advanced personal vaporiser) where the device is tube-shaped with a mouthpiece at one end.

   38. Vegetable glycerine (VG)

A natural, colourless and odourless ingredient, one of the two primary e-liquid ingredients. 

   39. Wattage

A measure of the rate at which electrical energy is used by any electrical product. The wattage number measures the power used by a Vape device. Usually, the higher the wattage, the bigger the vapour cloud.
