Hon Lik, the inventor of the modern electronic cigarette, filed patents on his invention in China, the United States and the European Union in 2003. The first electronic cigarette was manufactured in 2004 in Shenyang, China. Electronic cigarette users since then have boomed to an estimated 68 million worldwide in 2020. Below we hope to answer some of the most often asked questions we are asked. Click the headers to expand.

The Basics

An e-cigarette (electronic cigarette or vaping device) is a hand held battery-operated device that delivers vapour from heating a nicotine-based solution otherwise known as e-liquid.

Devices come in many variations; however, there are some shared components. Most e-cigarettes usually have the following components; a battery, a tank (clearomiser or cartomiser), and an atomiser. 

There are currently four device generations available on the market:

• 1st generation devices resemble the look of cigarettes (aka ‘cig-a-likes’). They contain an automatic battery (90 or 120 mAh) with a short charge time and small cartomizer.

• 2nd generation devices consist of a manual, higher-capacity battery (650 – 1600 mAh) and charged by USB. These provide a longer life span, more vapour production and a better throat hit. The e-liquid can be refilled in the clearomizer. There is also an additional safety on/off feature.  There is a wide choice of atomizers or clearomizers that are available for this type of device.

• 3rd generation devices (aka ‘Mods’ from modifications). Mod devices come in all sorts of shapes and sizes.  They can be typified by their larger battery capacity and tend to be used by people who explore the notion of the devices using larger tanks and lower resistance atomizers thus producing higher volumes of vapour.

• Pods/Disposables These are devices prefilled with e-liquid and available either as a disposable pod with rechargeable battery as in the DOT Pro or a completely single use device as with the DOT Go


There are typically 4 components in e-liquids:

•             Propylene glycol (PG) – provides a bigger throat hit and a stronger flavour.

•             Vegetable glycerine (VG) – provides more vapour, a sweeter taste but subtle flavour.

•             Flavouring – available in a wide range of varieties.

•             Nicotine – available in different strengths up to a maximum of 20mg per ml or 2.0%.

PG, VG and nicotine are pharmaceutical grade and the flavourings used are food grade. The majority of e-liquids in 10ml bottles consist of a 50-50 PG/VG base for a balanced throat hit and vapour production. VG heavy e-liquids are commonly available in larger bottles 60/120ml and do not contain nicotine when purchased, these are known as “shortfills”. An 18mg “Nicotine Shot” is then added to the bottle (1 per 60ml) to create a 3mg or 0.3% e-liquid.

There are not any ‘rights’ or ‘wrongs’ when it comes to choosing e-liquid or e-cigarettes.  The key is finding the right combination that will enable you to feel comfortable and satisfied. Increasing the nicotine percentage increases the throat hit to further tailor your vaping experience.

E-liquids exposed to heat, light and air during storage will darken in colour over time due to photo-oxidation. This process will not affect the nicotine potency and has little effect on the vapour and flavour. Keeping your e-liquid stored in dark, cool and dry conditions will slow down this process though.

On average, a vaper will go through about 3ml of e-liquid per day but this is very device dependant.  There are lots of studies that reflect the use of nicotine via various means with some research indicating that the human body is able to self-titrate (or control) nicotine dosage, therefore usage will also differ from individual to individual.


Batteries come in all sorts of sizes but every battery has the same function which is to supply the power to the atomiser, which in turn heats the coil and produces vapour. Most devices available are turned on/off by quickly clicking the LED button 3 or 5 times. Batteries can vary in power and also how they are controlled. Most eGo style batteries have a power output of 3.7 volts, whereas mods (for the advanced users) can vary the power (voltage) or Wattage (electrical power expressed in watts). Below are some phrase you will come across when choosing a vaping device.

mAh –  Means Milliamps per hour and refers to the battery capacity (or how much energy they can store).  The higher the mAh, the longer the battery will last between charges.

Variable Voltage Power – Some batteries have a Variable Voltage (VV) option.  You can set the voltage of the battery and control the amount of power coming from it.  This allows you to use different resistance atomizers and still get the desired throat hit and vapour production by adjusting the power.

Variable Wattage Power – Variable Wattage (VW) allows you to control how many watts your device will produce. Variable wattage will allow you to set the wattage, no matter what resistance atomizer you use with the device. If you set it to a desired wattage, it will always give you the same outcome no matter what resistance atomizer you use.

All our Vaping Kits will come with a charger which is suitable for that device. Always use the charger provided with the device. Incorrect or incompatible chargers or wall plugs (such as ipad chargers) can result in failure as the amperage may be too high.

Tanks / Clearomisers

A clearomiser or tank are basically the same and are the parts that you fill with e-liquid. They consist of an atomiser or coil (usually replaceable) and a tank that holds the e-liquid.  The atomiser/coil is the heating element that produces vapour. It consists of a wire or milled metal that is wrapped around a wicking material such as organic cotton that soaks up the e-liquid. The wire receives a current from the battery, which in turn heats up and vaporizes the e-liquid. The amount of vapour produced will depend on the battery power as well as the atomisers resistance/ohms. Ohms is a measure of electrical resistance or how freely electricity is able to travel through something.  The lower the number (0.5 ohms) the hotter the atomizer will heat up.  The higher the number (1.8 ohms) the cooler the vape will be.

TRP Regulations 2016

The Tobacco and Related Products Regulations 2016 came into force on 20th May 2016 and are regulated by the MHRA

The MHRA is the competent authority for a notification scheme for e-cigarettes and refill containers in Great Britain and Northern Ireland and is responsible for implementing the majority of provisions under Part 6 of the Tobacco and Related Products Regulations 2016 (TRPR), as amended.

The TRPR introduced rules which ensure:

  • Minimum standards for the safety and quality of all e-cigarettes and refill containers
  • That information is provided to consumers so that they can make informed choices
  • An environment that protects children from starting to use these products.

The requirements:

  • Restrict e-cigarette tanks to a capacity of no more than 2ml
  • Restrict the maximum volume of nicotine-containing e-liquid for sale in one refill container to 10ml
  • Restrict e-liquids to a nicotine strength of no more than 20mg/ml
  • Require nicotine-containing products or their packaging to be child-resistant and tamper evident
  • Ban certain ingredients including colourings, caffeine and taurine
  • Include new labelling requirements and warnings
  • Require all e-cigarettes and e-liquids be notified and published by the MHRA before they can be sold
