As the number of types of electronic cigarettes is increasing, many of you must be wondering which one to choose and by what criteria so that you will not make a mistake. In this article, we will explain how to choose an e-cigarette (vape) without making a mistake.Tobacco leaf heating type and liquid heating typeWhat is a tobacco leaf heating type?Tobacco leaf-heated e-cigarettes, as typified by IQOS, are not, strictly speaking, electronic cigarettes.To briefly explain their structure, tobacco leaves are heated using electricity, and the vapor vaporized is inhaled.As a result, tar is greatly reduced, but nicotine can still be inhaled, making it a popular product among smokers.The main selling point of these cigarettes is that they suppress the unpleasant odor characteristic of cigarettes and allow smokers to enjoy the original flavor of the cigarettes.Currently in Japan, there are three types of heated tobacco leaf products on the market: IQOS by PHILIP MORRIS, Ploom TECH by JT, and glo by BAT.Next are liquid-heated e-cigarettes called vapes, which can be broadly divided into three types: liquid, cartridge, and disposable.All three types are nicotine- and tar-free because they use electricity to heat liquid of various flavors instead of tobacco leaves.Since the special liquid is heated to produce vapor and pseudo-smoke, what you inhale is the so-called aroma containing flavors, and since no nicotine-added liquid is currently sold in Japan, it is no different from smoking cessation.What is a liquid-heated vape?Vape is the common name from electronic cigarette manufacturer, which are no longer shaped like cigarettes as in the past, but are more stylish in design.They produce smoke just like cigarettes, so they look like real cigarettes, but this is because a small amount of liquid is heated to produce vapor, which looks like cigarette smoke. Therefore, there are no worries about secondhand smoke or fire, which are concerns with cigarettes.Select by shape and designThe shapes and designs of e-cigarettes can be roughly divided into the following categories.Cartridge-integrated typeThis is a disposable type of e-cigarette that requires no troublesome maintenance. Since the body and liquid are integrated, they may be a little more expensive. However, the appearance is similar to that of a cigarette, so it may be close to the image of an e-cigarette.Integrated tank typeThere are also products on the market that are simple in design and do not even have a power button, but are turned on by simply sucking in through the mouthpiece. While this type of e-cigarette can be smoked easily on the go, it is difficult to clean, and if it is damaged, the entire tank may have to be replaced.Pen and stick typeMany of them do not have adjustable outputs, such as voltage, and it is difficult to adjust to TPO immediately. There are also disposable vape pods in fashionable colors, and overall, they are small enough to fit in one's hand, making them very convenient to carry around. Many of them are simple in function, and many of them may have a feminine design.Box-shapedMany of them have a bulky design, but many of them have a variety of functions. There are two types: one with an integrated battery and one with a separate battery, and the integrated type is not suitable for portable use.Select by the amount of smokeThe amount of smoke from an e-cigarette can be adjusted. If the atomizer, which is the container for the liquid, is equipped with an air float control that adjusts air resistance, the amount of smoke can be adjusted instantly. Also, simply changing the liquid used to one with a higher concentration of VG (glycerin) will increase the amount of smoke compared to one with a lower concentration.If the e-cigarette has an adjustable voltage, it is easy to produce thicker smoke by simply setting the voltage higher, but it requires more power to produce a lot of smoke. This power is determined by the voltage of the battery and the resistance of the coil inside the atomizer. The higher the power, the more smoke is produced and the more smoke you can enjoy.If you are knowledgeable, you can change the atomizer's components to your own specifications, but if you are new to the market, it is better to purchase an electronic cigarette with an explosive smoking specification, as there are a number of them on the market.
