As far as the average e-cig user is concerned, electronic cigarettes are just composed of 3 main parts. Those three parts are the battery, the cartridge, and the e-liquid.
E-liquid, sometimes called E-Juice, is the fuel of any electronic smoking device. It contains flavoring and nicotine, along with a base to hold it all together. Once the device is activated, the e-liquid becomes vapor to be inhaled. There are almost an infinite amount of e-liquid flavors available all over the internet, so it’s important to understand how it works.
E-Liquid comes not only in different flavors but with the various amounts of nicotine as well. The strength of the liquid is typically measured in milligrams of nicotine per milliliter of liquid. You’ll usually see strengths labeled with “mg/ml.” Below is some information on typical nicotine levels and which one would be best for you:
6 mg/ml: Low volume smoker, less than half a pack per day
12 mg/ml: Average smoker, between half and full pack a day
18 mg/ml: High volume smoker, more than a pack per day
24 mg/ml: Chain smoker, this is typically the highest strength sold by any reputable retailer
If you buy a starter kit, which we recommend for first-time buyers, it will include e-liquid. But it is the one part of an e-cig that you will need to replace regularly.
Cartomizers: this piece of an electronic cigarette has many names. Cartomizer, cartridge, clearomizer, tank, and often any of those two words combined. But they all serve the same function. It is the piece that holds the reservoir of e-liquid and facilitates the process of vaporizing it.
Inside the cartridge is a small device called an atomizer, which is the vaporizing element. As the user puffs on his e-cigarette, the cartomizer feeds liquid onto the atomizer via small fiber wicks. If you buy a cheap cartridge, it may become frustrating for you because there are many things that can go wrong with cheap cartridges. However, some brands have very high-quality cartridges that work very well and will not require frequent replacement.
The final piece of the puzzle is the battery, which provides the power needed to generate the atomizer and vaporize the e-liquid. Batteries are relatively straightforward: the bigger the battery, the longer it’s going to last and the more vapor it’s going to be able to generate. Some people prefer the miniature e-cigarettes because they want to mimic the tobacco cigarette experience. Others prefer the eGo style (sold by Halo and Apollo) because they are a bit larger and have a longer battery life. Some eGo models even allow you to adjust how much power you want your battery to release when you are puffing. Other vapers have gargantuan “mods” that have incredibly long battery life but are not portable at all.
