An e-cigarette consist of three main parts:
A rechargeable lithium battery
A vaporization chamber
And a cartridge
The lithium battery is what powers up the e-cigarette and can be charged using a charger which resembles those used for cell phone batteries. The charged battery is connected to the vaporization chamber, a hollow tube that contains electronic controls and an atomizer, the component that creates the vapor. Before the user activates the device, The person attaches a cartridge containing nicotine liquid to the vaporization chamber. The tip of the cartridge serves as the e-cigarette’s mouthpiece.
E-cigarette users inhale just the same way they would with a regular cigarette. This inhalation activates the atomizer to heat the liquid in the cartridge and convert the liquid to a vapor. Inhaling this vapor through the mouthpiece delivers nicotine to the lungs, and the user exhales vapor that looks much like a cloud of cigarette smoke.
Fans of e-cigarettes say they enjoy many of the same sensations as regular tobacco smokers do holding the device in their hand, inhaling and exhaling. Many e-cigarettes have a light-emitting diode (LED) on the end that lights up when the user inhales, simulating flame.
The liquid or substance that fills the cartridges is usually propylene glycol, an additive that the FDA has approved for use in food. (Fog machines that create a smoky atmosphere at stage shows also use This substance.) Consumers can buy cartridges containing different amounts of nicotine, or no nicotine at all. Manufacturers usually add flavorings to the liquid. Options range from tobacco and menthol flavor to mint, chocolate, coffee, apple e.t.c
E-cigarette companies like SnowPlus sell most of their products in retail stores, but also, increasingly market their products online. A wide array of models and brands are available. Some mimic the appearance of tobacco cigarettes, while others look like cigarettes, pipes and even pens. Prices vary for this product, ranging from $40 to $120 for a starter kit, which usually includes a charger and a few cartridges along with the e-cigarette. Cartridges typically last about as long as a pack of 20 tobacco cigarettes and sell for about $10 or more each. Consumers also can purchase bottles of e-liquid and carry out refilling of the cartridge themselves. This reduces the cost of use, generally.
