the e-cigarette usues a personal atomizer to vaporize the liquid nicotine in the cartridge so it can be inhaled. Our e-cigarette models have two different types of atomizers. The disposable atomizer is build into the cartridges and is thrown away with each new cartridges. ( model ec100 ) The permanent or non-disposable atomizer is reused with each cartridge. Typically this type of atomizer will last about 25 cartridges until the vapor quality is reduced.
When you puffed on your ecigarette the battery sends power to the atomizer and it vaporizes the nicotine to creates a smoke like vapor, just like a real cigarette. A good quality atomizer will last longer and produce a consistent, better quality, and more flavorful vapor.
