As electronic cigarettes become increasingly popular, design and style variations appear on the market fairly regularly. However, the majority of electronic cigarettes (also known as personal vaporisers) are currently based upon one of 3 model types – the Penstyle, the Mini and the Supermini.
Penstyle electronic cigarettes, which are similar in size and style to a typical pen, are the longest
and biggest of the 3 model types. Because of their size compared to other models, Penstyle batteries tend to hold their charge longer and their cartridges hold a greater volume of e liquid (or e-juice as it's also known).
As a rough guide, the Penstyleelectronic cigarette cartridgeholds 1ml of e-juice which provides about 100 puffs, the approximate equivalent of between 7 and 10 tobacco cigarettes.
Mini electronic cigarettes are more or less midway in size between the Penstyle and Supermini. The Mini e-cigarette battery holds less charge and the cartridges less juice than the Penstyle. Mini electronic cigarettes appear to be the most popular of the 3 basic models.
As a rough guide, a Mini cartridge holds 0.5ml of e-juice which provides about 50-75 puffs, the approximate equivalent of 5 or 6 tobacco cigarettes.
Supermini electronic cigarettes are the smallest and least popular of the 3 model types; their batteries hold the least charge and cartridges the least juice. However, the Supermini can look remarkably realistic even close-up, which appeals to many people purchasing electronic cigarettes for the first time.
As a rough guide, a Supermini cartridge holds 0.3ml of e-juice which provides about 20-30 puffs, the approximate equivalent of between 1 and 3 tobacco cigarettes.
Because of their greater size, e-pipe cartridges hold the greatest volume of e-juice of any e-smoking device. One e-pipe cartridge provides the equivalent number of 'puffs' or inhalations as approximately 14 or 15 tobacco cigarettes.
As one would expect, e-cigars are larger than Penstyle electronic cigarettes allowing for greater cartridge and battery size. A typical e-cigar cartridge holds 1.2ml of e-juice which provides about 120-130 puffs, the rough equivalent of between 10 and 12 tobacco cigarettes.
Disposable electronic cigarettes and e-cigars come fully charged, filled with e-juice and ready to vape. Typical devices have a lifespan of approximately 3 days, depending on the model and how heavily it's used.
