Liquid tank capacity
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.
Minimum resistance
The smallest resistance of the heating coil of an electronic cigarette.
The meaning of this parameter will be different, depending on which part of the device is in question (see "Type"). So, for atomizers, this parameter is given if spare heaters are supplied in the kit — accordingly, it is indicated for the “head” with the lowest resistance. For a battery mod, this is the smallest resistance that can be connected to it. And in starter kits, the minimum resistance is also usually indicated by the battery mod; low-resistance "heads" in such cases may or may not be included in the delivery.
Anyway, data on the minimum resistance is important in the mutual selection of an atomizer and a battery mod (including when creating custom windings) — connecting an atomizer with too low resistance is fraught with overloads and various unpleasant consequences, up to fire. However, this parameter is of particular importance for lovers of the so-called subohm — soaring at a low heater resistance (up to 1 ohm), which allows you to achieve high steam saturation (when the resistance decreases, the power increases). Not all batteries are capable of working with sub-ohm heaters, so the suitability of a battery mod for such vaping needs to be clarified.
Capacity
The battery capacity of an e-cigarette or separately sold battery mod. This parameter is indicated only for models with non-removable batteries (see "Battery type"): replaceable cells can be produced in different capacities.
The larger the battery, the longer you can use the device without recharging the battery. However the actual power consumption and, accordingly, the battery life of different models will be different, therefore, only devices with similar operating voltages and atomizer resistances can be compared in terms of capacity.
In general, if battery life is important to you, it is quite possible to proceed from the principle “the more capacious the battery, the better”; and to save money, you can choose a relatively weak battery. It is also worth mentioning that there are schemes for calculating the optimal battery capacity depending on the power, atomizer resistance, etc.; these schemes can be found in special sources.
Minimum voltage
The lowest voltage that the battery mod can supply to the atomizer.
The meaning of this parameter depends on the type of battery mod and the functions of the board (see above). So, in mechanical and simple electronic modes, the smallest value to which the battery voltage can drop before it turns off and requires charging is usually indicated here. Knowing this parameter, as well as the resistance of the atomizer, you can calculate the minimum guaranteed vaping power.
If we are talking about a mod with adjustments like varivolt or variwatt, then the minimum voltage is also the lowest voltage that can be set manually in the settings. This may be necessary to reduce the power and, accordingly, the intensity of soaring — for example, if the gas station has a very rich taste, and abundant dense steam would be overkill. In adjustable battery packs, the lower the minimum voltage (with the same maximum voltage), the wider the adjustment range, the more options the vaper has to adjust the vaping parameters. See “Maximum voltage".
Tank material
The material from which the flask of the complete atomizer is made. Most often, it means the material from which the transparent insert in the body (usually steel) is made, with the exception of all-steel flasks, see below for more details about them.
—
Glass. The most popular flask material in modern vapes. The glass does more than just allow you to see the contents of the flask — this transparency is maintained for a long time, as the glass surface is highly resistant to scratches. In addition, the walls of the flask are chemically inert, they do not react with the "slurry", whatever its composition; and the fragility of the walls is compensated by their thickness, and sometimes by special additives in the composition of the glass. This material is somewhat more expensive than plastic, but in fact this difference is insignificant.
— Plastic.
Plastic flasks, like glass, are usually made transparent, which allows you to monitor the amount of liquid; at the same time, they are much cheaper, it is very difficult to break such a container, and fragments from plastic are not as dangerous as glass ones. At the same time, this material is easily covered with scratches and quickly becomes cloudy during use. In addition, some types of plastic (especially inexpensive ones) can react with substances that make up e-liquids (manufacturers of both flasks and refills try to avoid this phenomenon, but
...a full guarantee cannot be given). As a result, this option is not particularly popular, it is typical mainly for low-cost devices created with the expectation of maximum cost reduction.
— Stainless steel. Stainless steel flasks are notable primarily for their high strength — even under a very strong load, the steel tank is more likely to flatten than crack. Yes, and resistance to corrosion can also be written down as advantages. At the same time, this material has a critical drawback that negates all its advantages — it is opaque. As a result, it is possible to monitor the liquid level in such a flask only by indirect signs — for example, by changing the taste or the amount of steam. This, to put it mildly, is inconvenient, so steel flasks are used extremely rarely — and not so much for practical reasons, but as an element of unusual design.
