Wick & Wire e-cigarettes

An electronic cigarette, also known as an e-cigarette, personal vaporizer or PV, is an electronic inhaler that vaporizes a liquid solution into an aerosol mist, simulating the act of tobacco smoking. Electronic cigarettes are no longer marketed as smoking cessation-aids or tobacco replacement in most countries. There may be similarities between conventional and some electronic cigarettes in the physical design and the nicotine release, which may approximate the same amount of nicotine as a conventional cigarette. There are also many electronic cigarettes which do not resemble conventional cigarettes at all. The amount of nicotine contained can also be chosen by the user, with many people choosing no nicotine at all.

Atomizer
The atomizer contains a small heating coil that vaporizes the liquid, and generally consists of a simple filament and wicking metal mesh or silica wick to draw the liquid in. It is positioned in the center of the three components that make up the entire electronic cigarette cylinder, as the cartridge attaches to one end, and the power unit to the other. The atomizer's filament will lose efficiency over time due to a buildup of sediment, or "burns out" entirely, requiring replacement. In some models, the cartridge and atomizer component are integrated, known as a cartomizer.

Battery
Most portable power units contain a lithium-ion rechargeable battery and makes the largest component of an electronic cigarette. This may contain an electronic airflow sensor so that activation is triggered simply by drawing breath through the device. Other models come with a power switch, which must be held during operation. A LED to announce activation may also be equipped in the front of power unit casing.
Batteries are usually charged via AC outlet, car or USB. Some manufacturers also offer a cigarette-pack-like portable charging case (PCC), which contains a larger battery to charge smaller batteries of individual e-cigarettes.

Liquid

Liquid for producing vapor in electronic cigarettes, known as e-juice or e-liquid, is a solution of propylene glycol (PG) and/or vegetable glycerin (VG) and/or polyethylene glycol 400 (PEG400) mixed with concentrated flavors, and optionally, a variable percent of a liquid nicotine concentrate.

They are often sold in a bottle or as pre-filled disposable cartridges. Many manufacturers offer dozens of flavors which resemble the taste of regular tobacco, menthol, vanilla, coffee, cola and various fruits, but nicotine concentrations vary by manufacturers. The standard notation "mg/ml" is often used in labeling, sometimes shortened to a simple "mg".Nicotine-free solutions are also common.

Some electronic cigarette users opt to make their own e-juice in a form known as "DIY".

 

Kits

 

There are dozens of e-cigarette model types sold online and in stores, all under hundreds of different brand names. Most electronic cigarette users initially purchase starter kits that contain a battery, USB charger and a selection of cartomizers (cartridges). Some kits also include a portable charging case (PCC).

 

Mods

 

A more advanced area of the electronic cigarette are the mod batteries, these batteries allow the user to experiment with different voltages and/or wattages. Changing the volts/watts of your battery to increase its power output causes the flavour to burn at a hotter rate, which in turn can help with the overall taste. Mod batteries are not for the beginner, they require a little background knowledge in ohms law. Once understood, the mod battery opens up a whole new area of vaping. The most popular mod battery at the moment is the ProVari, with the Vamo a close second. Both batteries come with built-in safety features that prevent the battery from shorting out.
