NEW WEBSTORE IS ONLINE CHECK IT OUT HERE!
Welcome to the Wicked Vapors site - a meeting ground for vapers at Fort Gordon, and friends from everywhere. This site is where we discuss new e-cigarette issues we've seen in the news, online, on tv, and other things like flavors, suggestions, and some basics that those new to vaping may want to know! You'll see that we point you to the E-cigarette Forum (ECF) quite often, because that's where the mass of vapers are talking, and there's some awesome information out there.
Thanks for visiting!
Taken from wikipedia:
An electronic cigarette or "e-cigarette" is a battery-powered device that provides inhaled doses of nicotine by heating a nicotine-chemical solution into a vapor. It is an alternative to smoked tobacco products, such as cigarettes, cigars, or pipes. In addition to nicotine delivery, this vapor also provides a flavorand physical sensation similar to that of inhaled tobacco smoke, while no tobacco, smoke, or combustion is actually involved in its operation.
An electronic cigarette usually takes the form of some manner of elongated tube, though many are designed to resemble the outward appearance of real smoking products, like cigarettes, cigars, and pipes. A common design is also the "pen-style", so named for its visual resemblance to a ballpoint pen.
Most electronic cigarettes are reusable devices with replaceable and refillable parts. A number of disposable electronic cigarettes have also been developed.

When a user inhales through the device, air flow is detected by a sensor, which activates a heating element that vaporizes a nicotine solution stored in the mouthpiece. It is this vapor that is inhaled by the user. On some models an LED on the opposite end of the device is also activated during inhalation, which serves as an indicator of use, and simulates the glow of actual burning tobacco.
The mouthpiece is a small disposable plastic cup affixed to the end of the tube. Inside, the piece contains an absorbent material that is moistened with a flavorednicotine liquid solution. The mouthpiece is referred to in the industry as a "cartridge". When the liquid in the cartridge has been depleted, it can either be refilled by the user, or replaced with another pre-filled cartridge.
The heating element serves to vaporize the liquid in the mouthpiece so that it can be inhaled. This component is referred to in the industry as an "atomizer". Some models combine atomizer and cartridge into one disposable component referred to as "cartomizer".
Most electronic cigarettes employ a lithium-ion rechargeable battery to power the heating element. Battery life varies depending on the battery type and size, frequency of use, and operating environment. Many different battery charger types are available, such as wall outlet, car, and USB. The battery is generally the largest component of an electronic cigarette.
Most electronic cigarettes employ an electronic airflow sensor to automatically activate upon inhalation, while some models instead have a manual button that the user must press while inhaling. Various other electronic circuits are usually employed as well, such as a timed cutoff switch to prevent overheating, and an LED to signal activation of the device. An orange-colored light is often chosen for its visual resemblance to actual burning tobacco in the front of the cigarette.
While some larger electronic cigarette models employ an independently replaceable standard-size battery cell, many models are too small to house a standard-size cell and instead require a proprietary component made by the electronic cigarette manufacturer. For those models, the battery and electronic components are housed within a single replaceable part, which is generally referred to in the industry simply as the "battery" — even though it actually contains many other components as well.
