The volume of the liquid tank provided in the design of the atomizer. Note that this parameter can be specified even for squonk atomizers (see "Filling type"): although they work with an external tank, however, a certain amount of "liquid" can fit in the evaporator itself.
The larger the tank, the more liquid you can keep in an electronic cigarette and the less often you have to refill it. On the other hand, capacious tanks have the appropriate dimensions, and too large a tank would be inconvenient, and liquids are consumed relatively little even in one long session of soaring. As a result, a volume
of more than 6 mL is already considered quite large for vapes, and in the smallest models this figure
does not exceed 2 mL.
Also note that when choosing a tank capacity, manufacturers usually take into account the resistance of the spiral, the power of the battery (if it is included) and other parameters that affect the expected flow rate of the liquid. There is no hard dependency here, however, in general, more powerful atomizers are usually equipped with larger tanks.
The material from which the body of the device is made.
This parameter is relevant primarily for battery mods: they can be made from a wide variety of materials, while atomizers do not differ in variety (the standard option is stainless steel, with a few exceptions; see below for details). Actually, for ready-made kits (including POD systems, see "Type"), this paragraph just indicates the material of the battery mod. Here is a more detailed description of specific options:
—
Stainless steel. Perhaps the most popular material for electronic cigarettes and their components — of all types and price categories. At a relatively low cost, stainless steel is strong, reliable, durable and not subject to scratches and corrosion. Of the shortcomings of this material, one can only note a rather large weight, but some, on the contrary, consider this moment an advantage: a massive metal case gives the impression of solidity and quality. Also, steel, like any metal, can cool the skin at low air temperatures and slide in the hands; however, in order to avoid all this, various linings (for example, made of rubber or soft-touch plastic) can be provided on the case to eliminate this drawback.
—
Zinc alloy. Another fairly popular material, which is actually a compromise between stainless steel and aluminium. Zinc weighs less than steel and costs less than aluminium alloys; at the same time, this
...material perfectly resists corrosion and has high strength, which led to its prevalence.
— Aluminium. Perhaps the most advanced metal in terms of practical characteristics: aluminium is light, strong and absolutely insensitive to corrosion. Its main disadvantage is a rather high price, while the described advantages are rarely decisive in comparison with the same steel or zinc. Therefore, aluminium cases are quite rare; at the same time, it is worth noting that this material is found not only in battery mods, but also in atomizers.
— Plastic. Inexpensive material, which also has a small weight and is able to take on a wide variety of colours. However, this is where the advantages of plastic, in fact, are exhausted: in terms of strength and scratch resistance, it is noticeably inferior to metals, and it can melt from strong heat. However there are advanced grades of plastic, but instead of them, most manufacturers prefer to use steel or other metal in vapes. As a result, plastic cases are rare, and mostly among entry-level models.
— Copper. The material used mainly as a design material — to give the case an unusual appearance (copper has a characteristic reddish tint). From the point of view of practical properties, such cases are similar to steel ones — in particular, they are strong, massive and scratch resistant. On the other hand, copper tolerates moisture worse, stains can appear on it even from constant contact with the skin. However, the main drawback of this material is its high price, which determined the specifics of its application.
— Brass. Another metal used primarily for aesthetic rather than practical reasons. It is similar in properties to copper described above and differs only in colour (shades of yellow) and somewhat greater resistance to oxidation (although it all depends on the specific type of brass).
— Wood. Wooden cases look interesting due to the characteristic colours and patterns. At the same time, this material is not very practical: it is prone to cracks and splits from impacts, it is easily scratched, and it can swell and warp from prolonged exposure to moisture. In addition, wooden cases are quite expensive (in part, this is a payment for the style). So, choosing a battery mod in such a design is worth it only in cases where the ability to “stand out from the crowd” is more important for you than the shortcomings described.
— Ceramics, Special high-strength ceramics are highly resistant to wear: such a case is very difficult to scratch, so it looks like new for a long time. On the other hand, this material may crack on impact (whereas metal is more likely to only slightly bend). Therefore, ceramic cases are extremely rare — especially since they are not cheap.
