Vaping is the process of smoking an electronic cigarette, also known as an e-cig. An electronic cigarette is an alternative to smoking regular cigarettes. It has three main components: a battery, a heating element, and a refillable cartridge. They come in many shapes and sizes to fit many different needs. When choosing an e-cig, the consumer can decide what features matter most and choose a device that best fits his or her specific needs. Some customers prefer longer battery life, while others want enhanced performance, and still others want a certain look.
