Since the introduction of the first commercially successful e-cigarettes in 2003, vaping devices have been continuously improved to be made more efficient and effective. The first-generation devices, called cig-a-likes, were similar in appearance to conventional cigarettes. It was also when the term ‘electronic cigarette’ originated. The cartomizer, which combined a flavoured cartridge and an atomizer, was introduced in 2006. The second-generation vaping devices (vape pens) were designed to enhance the performance power of batteries and atomizers. These devices were used as starter kits by people who were new to vaping. Vape pen improved upon the weaknesses of cig-a-likes and created a better vaping experience, featuring a button that activated the firing mechanism while turning the battery on/off, and also a chip that prevented overheating. Cartomizers, a combination of cartridges and atomizers, were introduced at this time. Clearomizers, which followed the cartomizers, featured transparent tanks that helped visualize the e-liquid levels in them. They also had silica wicks that delivered the e-liquid to the heating coil. The third-generation mods were further improved versions, with more power and personalization. The advanced personal vaping devices were provided with higher wattage, variable wattage and voltage, digital display, temperature setting, sub-Ohm tanks, airflow control etc.
The current day fourth-generation vaping devices consist of vape pens with higher battery power and refillable cartridges, with provision of pod-kits and box mods, allowing faster inhalation. The current day vape pens are sophisticated and intuitive, making vaping a thing of the future. Pods are the latest all-in-one devices, wherein pre-filled or refillable pods of e-liquid can just be snapped into place. They are provided with ready-prepped coils with or without nicotine, and are especially good with nicotine salts. With technology and consumer needs rapidly changing, the vaping devices currently in the market are far more advanced and personable.
