e-liquidOver recent years, more and more people have turned to e-cigarettes and vaping. Global sales of e-cigs exceeded £3.9 billion in 2015 and the UK is now the second biggest e-cig market in the world.

But what are e-cigs? How do they work? And why are more people using them than ever before? Keep reading for our comprehensive guide to electronic cigarettes for beginners.

Guide to e-cigs - How does an e-cig work?

Electronic cigarettes - often called 'e-cigs' - are designed for users to experience smoking in a safer, more controlled and healthier way then traditional cigarettes.

They come and in a variety of shapes and sizes depending on the type of model you are intending to use they produce a resemblance to 'smoke' in the form of vapour

They have many names including e-cigs, vape devices, electronic cigarettes and personal vaporisers. At a basic level they all do the same thing - vaporise e-liquid into an aerosol that you inhale.

E-cigs are normally made up of several components:

  • An atomiser - electricity passes through the coil heating the atomiser and, in turn, vaporises the e-liquid soaked on the wicking material
  • A liquid 'tank' - this keeps your atomiser soaked with e-liquid
  • A battery - this provides the electrical power to heat your atomiser coil and vaporise your e-liquid 
  • Output control - Most e-cigs have a way of ensuring electricity heats the atomiser in a controlled way, often through a switch or temperature control

When you are ready to ‘smoke’ (in this world we prefer to call this ‘vape’), you simply use a switch to control the e-cig (if there is one) and inhale on the mouthpiece end as you would with a traditional cigarette.

Why people use e-cigs and vape

There are many benefits to using e-cigs rather than traditional cigarettes. These include:

  • You avoid harmful chemicals - Smokers can avoid many of the harmful chemicals found in tobacco cigarettes including carbon monoxide, tar and lead
  • There is a range of flavours - Unlike traditional cigarettes, e-cigs are available in a wide range of flavours
  • They are cleaner - E-cigs don't produce smoke - what you see is vapour - meaning there is no ash, no smoke and no stale tobacco odour
  • They are harmless to others - Unlike cigarettes which can cause 'passive smoking' e-cigs don't cause potential harm to others
  • They are cheaper - The cost of e-cigs, vaping and liquids is generally cheaper than buying packets of cigarettes


2 types of e-cig you should know about

There are two main types of e-cig/vaping device currently available on the market.

1. Regular vaping

Regular e-cigs are the models you will commonly see. Typically pen-like in appearance, these models have a rechargeable battery pack, a liquid tank and can be refilled with your choice of e-liquid.

When you buy a regular e-cig, your pack will normally include a battery, the tank, a preinstalled atomiser, an extra replacement atomiser, and a micro USB cable for charging.

These models will have a coil resistance in the range from 1.0 ohm to 2.8 ohms. A typical commonly used coil resistance is 2.4 ohms.

A high PG e-liquid typically within a 0mg to 18mg nicotine level is used in conjunction with regular models.

2. Sub-Ohm vaping

Sub-ohm models are becoming increasingly popular, although they are generally for advanced users. Sub-ohm e-cigs produce high levels of vapour - you will often see a huge cloud of vapour - and an intense hit of flavour.

Sub-ohm models use lower resistance coils which mean that the hit is stronger and the cloud is larger; for this reason the nicotine levels for these models will not be over 6mg in strength. Some models also have a slightly warmer vape, meaning that it more closely resembles smoking traditional cigarettes.

A high VG e-liquid is required for sub-ohm models - typically used within a 0mg to 6mg nicotine level.

These models will have a coil resistance in the range 0.15 ohms to 1.0 ohm. A typical commonly used sub-coil resistance

Coil Resistances

A vaper (one who uses an e-cig device) must ensure that they do not mix the parts from a regular device with those from a sub-ohm device, unless the battery device can handle the different variations. A sub-ohm coil should never be used on a regular battery (such as an EGO type model), as this will overload the batteries output and may lead to a hazard.

Like regular batteries a sub-ohm battery device will also generally feature variable voltage (VV), the mode can usually be switched over to the more commonly used one in watts (W). Depending on your battery output a sub-ohm device can release huge amounts of instant power which is ideal for those looking towards using very low resistance coils that produce humongous clouds of vapour. These devices generally feature a controlled power output, so you can safely connect a regular resistance coil to a sub-ohm device and then adjust the output as required (but do check the manual instructions of your device first).

For both types of battery devices the lower the coil resistance used, the more power flows through it which produces warmer vapour, with larger clouds. Flavours can taste different and be more enjoyable at different heat settings; the variable controls allows the user to adjust the settings to ones preferred 'sweet spot'.

Growth and Legislation

This industry has gone through rapid growth over the last few years with an ever increasing range of new products marketed with advanced quality technologies. This allows users of vaping devices now to be able to really enjoy an amazing vaping experience, but do keep checking here at VapeHit to see the latest products available for your use.

The electronic cigarette industry is set to be legislated in the UK under the TPD (Tobacco Product Directive) which will harmonise and control the quality of electronic cigarette products and e-liquids. This will affect the range of products available and only those that are notified with an ECID number will be eligible for sale, with the law to be fully enforced in May 2017. This will further ensure consumers will be receiving a quality controlled product for their use.
