An electronic cigarette (E-Cigarette) is a battery powered device which is used to deliver nicotine into the body without the chemicals contained in cigarettes. Instead of burning tobacco, an e-cigarette heats up the e-liquid and turns it into vapour.

Components of an Electronic Cigarette

Most electronic cigarettes contain a battery, electronic circuits, atomizer, tank and a mouthpiece.

Battery and Electronic Circuits

These 2 components are the main part of an electronic cigarette are together are referred to as a Mod. Batteries in e-cigarettes are rechargeable Lithium-ion batteries and have a capacity ranging anywhere from 150 mAh to 2500 mAh.

Atomizer

The atomizer contains a heating element (Coil) and connects directly to the mod. The mod provides power which transfers through the atomizer to the coil, which results in heating the coil up and turning the e-liquid into vapour.

Tank

The tank of an e-cigarette contains the e-liquid as well as the atomizer. Tank sizes can vary from 0.3ml to 3ml.

Mouthpiece

The mouthpiece attaches to the tank and is the part that is placed in your mouth when vaping. Some tanks have built in mouthpieces while others have mouthpieces that can be removed and replaces at will.

E-liquid (E-juice)

E-liquid is made up of 4 different ingredients, namely, Vegetable Glycerin (VG), Propylene Glycol (PG), Nicotine and flavouring.
VG and PG are the base of any e-liquid and usually make up between 80 and 90% of the formula. Most e-liquids contain a ratio of 70% PG/ 30% VG, however these ratios vary depending on the e-liquid brand and users preference.


Nicotine strengths in e-liquid range from 0mg right up to 36mg, with 3 to 6mg being the most popular choice among vapers (people who use electronic cigarettes). People who are trying to switch over from cigarettes to vaping will usually start with a higher concentration of nicotine and will slowly work their way down.


Flavouring usually makes up between 5 and 15% of an e-liquid formula and is the most important ingredient. A bottle of e-liquid which contains the right combination of flavours can taste amazing and will make a huge difference for someone who is trying to switch over from cigarettes.
