Vape resistance calculator. Reprova Coil Calc - perhaps the most convenient mobile application-winding calculator Calculation of coil resistance

The atomizer coil is one of the most important elements of an electronic cigarette. You can implement winding either on your own or buy ready-made spirals. It all depends on the skills and preferences of the user of such a device.

We have already talked about how to make winding with your own hands in one of our publications, but we have not yet talked about the role of this element in the vaping process itself.

Today we will talk about what ready-made coils give to vapes, whether it makes sense to wind the evaporator on your own, and how to calculate the resistance of an atomizer coil.

The coil of the evaporator is a very important component of an electronic cigarette, without which such gadgets simply will not be able to work.

The coil is installed on the base of a steam generator (atomizer, evaporator) and serves as a heat element, through which, in fact, the process of converting vape refills into the very vapor for which vapers buy such gadgets is possible.

Briefly about the main thing

So, as mentioned earlier, you can buy ready-made spirals that are designed for a certain resistance and are suitable for certain models of electronics.

However, moving to the stage of professional vaping, many vapers express a desire to wind their electronic vaporizers on their own, which provides many advantages:

  1. Saving.
    If we talk about long-term self-winding of the atomizer, then we are talking about colossal savings. Ready-made coils cost almost the same as a whole skein of Kanthal or nichrome wire, from which you can twist at least a dozen delicious coils.
  2. Skill level.
    This is, perhaps, why vapers come up with all sorts of stages for their mods. Everyone who winds an atomizer is trying to come up with something new to show their level of professionalism in this truly fascinating culture.
  3. Achieving certain vape targets.
    For example, a single-coil serviceable atomizer can be wound in such a way that it produces twice as much vapor as its more modern counterpart. Yes, yes, all this thanks to well-chosen winding. Whereas ready-made spirals are designed only for certain resistance values.

Resistance calculation: why and how to do it correctly?

The main characteristic of any electronic cigarette coil is resistance.

So, for example, for popular models of Subtanks, both standard windings of 1-0.5 Ohms, and those that differ from the sold serviced bases, either less up to 0.3 Ohms inclusive, or more, are perfectly suitable.

Optimal resistance values.

The winding resistance of steam generators depends on a number of factors, including:

  1. Winding length.
    This refers to the number of turns that make up the spiral. If you remember from physics, the law states that the longer the path along which the voltage travels, the higher the resistance of the current. By the way, this is the most important rule that needs to be taken into account when servicing atomizers yourself.
  2. Thickness.
    Here again we turn to the laws of physics. The smaller the thickness used for winding, the higher the resistance to the spiral and vice versa. But at the same time, it is worth noting the following: it is not so easy to make new turns from thicker wire, for example, 0.5 mm. And besides, the larger the winding area, the greater the amount of heat required to warm it up. Hence the rapid battery consumption.
  3. Resistance indicators.
    This value largely depends on the material used for winding the spiral. In accordance with the operational characteristics of the consumables, for each of them it is necessary to select a special thickness and length, as well as the number of turns to implement the finished stage.

When creating a winding, you must always remember that the more turns you get, and the larger the diametrical size of the spiral, the larger the heated area. Due to this, it is possible to obtain thicker and more voluminous steam.

But at the same time, it is impossible to make coils of infinite length, because restrictions are imposed by both the vape itself and the atomizer, which may simply not cope with the task, which will lead to their failure.

In addition, when doing independent maintenance of electronic evaporators, namely winding it, you need to remember and understand Ohm’s laws, which play an important role here.

If you wind a coil for a vape without following any rules, this can lead to various kinds of problems, both in the operation of the device and other difficulties. But first things first, we will look at what will happen if you wind the atomizer incorrectly a little later.

For example, when winding a spiral on a SubTank, and for such, the resistance on the coils must be at least 0.5 Ohm, you need to remember that suitable gadgets are needed to service such stages.

In this case, for high-quality operation of the coils, it is necessary that the mod has a current strength of 15 Watts. However, today it is extremely difficult to find a device with such characteristics, so working with low-resistance windings is extremely difficult.

Advice! When choosing a winding, it is necessary to take into account not only the power indicators of the vape, but also its resistance. The largest selection of vaping gadgets today starts from 30 W and above.

In addition, in order to ensure a high-quality vaping process, you need to pay attention to the power source with which the vape is equipped. The batteries must contain high frequency current, otherwise the winding may overheat.

At low watts with nickel or titanium windings, low resistance can be achieved. However, if the electronic cigarette is not equipped with a thermal control function, then be prepared for the fact that this stage will very soon cease to fulfill its purpose.

Initially, the resistance of any material will be calculated according to the law that we all know from school: R=U/I. But this formula is not entirely complete. In our case, we also need to add the length of the spiral to it.

Calculation table.

To make it more clear, let's look at several examples of calculating the winding resistance for serviced electronic cigarette atomizers:

  1. If you need to obtain a winding resistance of 0.5 Ohm, then, relying on the formula proposed above, we expect that the A1 cable wire will be quite suitable for the implementation of the task. The thickness of the wire should not be more than 0.4 mm, coupled with a curl radius of 1.125 mm, approximately 5.5 turns will need to be made.
  2. Or here’s a second example: the required resistance on the coils is 0.3 Ohm. For winding we will use nickel wire. So, we take Nickel 200, the thickness of which is 0.2 mm. Here it will be sufficient to make 12 curls, with a radius of each of 1.25 mm.

At first glance, carrying out such calculations is not an easy task, but there are many options to simplify this task. On the Internet you can easily find special calculation programs called resistance calculators.

One of these programs that will help you carry out the correct calculation can be reprove or coiltoy, which, by the way, can be installed not only on a desktop computer, but also downloaded from the Google Play mobile application.

Few vapers do their own calculations. Most steamers prefer to use the appropriate programs: it is both fast and convenient.

For reference! Going for less than 1 ohm resistance has become very popular these days, with many professional vapers easily going as low as 0.05 ohms on their coils. This is the resistance that lovers of tasty and voluminous vaping prefer.

What happens if the calculation of the spiral resistance is performed incorrectly?

The question, of course, is very relevant and quite sensitive. We would like to warn you right away, be sure to read this information to the end, because not only the organization of a high-quality vaping process depends on it.

So, what are the consequences of incorrectly calculating the winding resistance of an atomizer on an electronic cigarette:

  1. If the resistance on the evaporator is low, then the worst thing that can happen is the poor performance of the entire gadget as a whole. Low-resistance vaping is only possible on vapes that operate at more than 15 Watts. Otherwise, the conversion process will either not take place at all, or liquid spitting will be observed (this is when, along with the steam, when inhaling, the vaping mixture enters the vaper’s mouth).
  2. If the resistance on the spiral is very high, then the consequences may be more serious. It’s good if you identify this problem in a timely manner and replace the winding with a more suitable one in terms of resistance. It will be worse if the vaper tries to light up the vape on this winding. Here even explosions of the entire gadget are possible. Is it worth talking about what can happen to a vaper if the mod flies into the air while taking a puff? A very sad picture...

Be that as it may, the resistance on the evaporator must correspond to the operational characteristics of both the atomizer itself and the electronics, in particular the power source.

Why does the resistance on a vape fluctuate?

A very pressing problem for vapers: it happens that during the vaping process the resistance jumps by different values. It produces 1.6 ohms, and after a few minutes the indicator changes to 2 ohms.

There are several explanations for this:

  1. The mounting screws that secure the winding to the base are not tightened tightly enough.
  2. The resistance of the resulting stage is not suitable for the electronics or the evaporator itself.
  3. Weak puff on the vaporizer and vape.
  4. Problems in the functionality of the control board.

Let's try to deal with this kind of trouble. Using a special tester or another mod that has the ability to control winding indicators, we measure the resistance value of the spiral.

In the absence of the opportunity to take measurements, but knowing the number of turns, the diametrical size of the wire, the diameter of the cord, you can enter these data into a special calculator, and the approximate resistance of the stage will be known.

If the results obtained meet the standards, then we move on. Slightly loosen the fixing screws, check the connection of the winding ends and re-tighten the fasteners. Testing the electronics again. The vape worked - great, no, we continue to look for the problem.

Resistance can vary greatly among different materials.

In the instructions for the electronic cigarette, which must be included with the mod, we look at the value of the resistance value. If these data do not match, then the only way out is to rewind the atomizer, completing the required number of curls. Let's test the gadget again. Everything is fine - we enjoy the soaring, no, we continue to work.

The third reason that the resistance on the electronics constantly fluctuates may be the fact that the atomizer has poor contact or the contacts on the vape itself are pressed. Here it is enough to check the size of the ends of the coil and the contacts themselves for the presence of dirt and other nuances that can lead to a poor connection between the evaporator and the mod. We check, and if a malfunction does not occur, we are happy.

If all this did not help eliminate the problem and the resistance on the atomizer continues to jump, then most likely there is a fault in the control board. Unfortunately, it is extremely difficult to solve this problem on your own. And if you are not a professional in this matter, then it is better to entrust your mod to specialists.

But the problem may not be with the evaporator. If you put a working atomizer on the vape and the problem remains, then the gadget itself is to blame. There is either a repair, which, as a rule, does not help solve the problem, or a complete replacement of the device.

Conclusion

At the end of our publication I would like to summarize:

  1. Before you begin servicing your vape, be sure to read the rules for such a procedure. In addition, you need to understand at least a little about physics, or at least know what resistance on a spiral is, how to regulate it and what its performance depends on.
  2. Remember, an incorrect resistance calculation or purchased unsuitable ready-made coil can cause a poor-quality vaping process, damage the gadget, or, even worse, harm the health of the vaper.
  3. To implement winding, give preference only to high-quality consumables. This approach will allow you to make a high-quality, high-quality and well-functioning coil for an electronic cigarette.
  4. If you use purchased spirals, then try to select them so that they fit well on your base. Here we are talking mainly about the operational characteristics of the electronics itself, that is, whether it will handle this or that stage.

That, in fact, is all we wanted to bring to your attention. We hope this information will help you organize quality service for your electronic cigarette. What kind of winding is on your vape: purchased or homemade?

And which one, in your opinion, performs better in the vaping process?

And which one do you think is

Using the online winding calculator, the calculations necessary to install from 1 to 4 spirals and determine the appropriate current power range for their optimal operation are carried out. Calculations are supported for coils that consist of a maximum of 6 parallel wires with a diameter of 0.10 to 1.02 millimeters. The power recommended by the coil calculator allows you to avoid overheating of the liquid, too rapid “coking” of the coils, and burning of the cotton wool, which greatly affects the taste properties of the coil. Let's look at the functionality of the calculator and get acquainted with the initial parameters:

  1. Number of wires: indicate the number of parallel wires in the spiral.
  2. Number of coils: set the required number of coils for installation.
  3. Spiral type: please specify option:
  • Normal– the arrangement of the turns is separate.
  • Micro– turns tightly adjacent to each other.
  • Clapton– the wire has an additional braid made of another wire with a smaller cross-section (appearance: like a guitar string).
  • Wire diameter – enter the diameter value.
  • Winding diameter – enter a number equal to the diameter of the winding base.
  • Number of turns – enter the number of turns. A choice of full and half turns is available.
  • If you are using two wires woven together, check the “Pigtail” sub-item.
  • Leg length - the length of the wire from the end of the spiral to the fastening.
  • Wire type - see markings on the package. Common - Kanthal A1.
  • Battery scale – operating voltage. The online calculator will give you a hint about the appropriate value. It all depends on resistance. Blue color means that the coils will not heat up well, green is the optimal value, red color indicates overheating.
  • How to use the winding calculator

    Let's say you need to wind it on a drip tape. Let's calculate for Kangertech KBOX Mini TC. As a result, the maximum current output is 20 Amperes, voltage is up to 4 Volts. Two spirals. The acceptable thickness of the electrical wire is 0.5-0.7 millimeters. A thin wire is bad for these powers, a thick wire is more likely to be weak.

    We set the initial parameters:

    1. The number of wires is “1”.
    2. The number of spirals is “2”.
    3. Type - Microcoil.
    4. Wire thickness – indicate 0.51 millimeters.
    5. Coil diameter – indicate 2.25 millimeters (ideal for drip).
    6. The number of turns is left unchanged. We will set the parameter later.
    7. We leave the length of the legs unchanged.
    8. We wind from Kanthal, so we indicate Kanthal A1
    9. Move the battery slider to the 4 Volt mark.

    Let's look at the calculation result.

    The result is a coil with a resistance of 0.25 Ohm, the optimal power value is 62.75 Watt, it is recommended to set 44.57 Watt. The calculation showed that the spiral consumes a current of 15.69 Amperes. This result for a board with 1 battery is close to ideal.

    If the parameters are not suitable, then experiment with the number of turns. But as the number of turns increases, it will be more difficult to heat the coil. And if you reduce it, then the working area of ​​evaporation will decrease. Remember that the ideal solution is to find a “golden mean”.

    Today I would like to tell you about such a necessary and convenient thing as a winding calculator. And not just review them all, but on the contrary, talk about the most convenient of them, in my opinion.

    Let me clarify right away that the calculator we are talking about is available both as an application for iOS or Android, and in the form of an online version on the website. The advantage of this approach is obvious: on the one hand, you can use the calculator on the big screen whenever it is convenient for you, and on the other hand, at any time you can switch to a mobile application, the interface of which is like two peas in a pod, which makes its use as familiar as possible. This can be convenient in many situations, for example, if you are too lazy to turn on the computer or if you are not at home, and so on.

    By the way, one of the applications that I found for myself personally: when I have any idea for winding, I can simply take my phone out of my pocket and specify all the parameters, check the approximate resistance and required power and understand which of my devices can handle it and which No.

    In general, there are actually a lot of applications, and most importantly, every advanced vaper will decide on them himself, as well as the need to have such an application.

    So, let's talk about the application Reprova Coil Calc.

    Let's first look at the interface and capabilities of the mobile version, and then I'll tell you a little about the site. Let me clarify that we will be talking about the version for iOS and in the screenshots you will see exactly that, simply because at the moment, unfortunately, I do not have devices for Android, but in general the versions are not particularly different, so this is not that important.

    Interface:

    The first thing that greets us after installing the application is the icon. Quite nice, with the Ohm symbol.

    Well, after all the preparations, we are greeted by the main screen of the application.

    If we talk about the interface as a whole, it is very convenient and intuitive; there are no heaps of menus or tabs in which you can get lost. One screen. All.

    A separate advantage is the presence of Russian localization, which makes using the application more convenient for people who are not fluent in English.

    Possibilities:
    The program's capabilities are quite extensive.

    You can choose the following options:

    • number of wires in a spiral (from 1 to 6)
    • number of spirals (from 1 to 4)
    • coil type (nanocoil/microcoil and regular)
    • wire diameter
    • diameter of turns (internal diameter of the spiral)
    • number of turns
    • length of legs (from spiral to racks)
    • wire type (material)
    Recommendations on the optimal power for your winding are also available, and you can save the spirals so that at any time you can see what you wound there before.

    Now a little more detail about several points.

    When selecting the coil diameter, you have access to specified values ​​in inches (inch) and millimeters (mm). The range is quite wide and covers all possible options that you will need when calculating. However, I would call the lack of the ability to enter your own values ​​a minus.

    Values ​​in millimeters start from 0.5 and end with 4mm, pitch varies from 0.1 to 0.5mm, in inches from 3/64 to 3/16

    The options available in millimeters are:

    In inches:

    • 11/64

    When choosing a wire diameter, the range will be from 0.10 to 1.02 mm, and, which is especially convenient, next to the values ​​in millimeters, AWG values ​​are given in parentheses. This is convenient when you read or watch videos about windings from American coilbuilders, because As a rule, they indicate wire diameters in AWG and not in millimeters. By the way, 28 gauge and 28AWG are the same thing, they can say either way.

    Available values:

    • 0.10mm (AWG 38)
    • 0.11mm (AWG 37)
    • 0.12mm (AWG 36)
    • 0.14mm (AWG 35)
    • 0.15mm
    • 0.16mm (AWG 34)
    • 0.18mm (AWG 33)
    • 0.20mm (AWG 32)
    • 0.22mm (AWG 31)
    • 0.25mm (AWG 30)
    • 0.28mm (AWG 29)
    • 0.30mm
    • 0.32mm (AWG 28)
    • 0.35mm

    • 1.0mm
    • 1.02mm (AWG 18)
    Thus, as you can see, the standard values ​​cover the entire range of wire diameters that can be used for winding.

    When choosing wire material, the following are available:

    • Nickel 200 (Ni)
    • Titanium (Ti)
    • SS AISI 304
    • Nichrome Cr20Ni80
    • Nichrome Cr15Ni60
    • Fechral H23YU5T
    • Kanthal D
    • Kanthal A1

    If we scroll down the screen, we see exactly what the program was made for - calculating resistance in accordance with the above parameters.

    But that is not all. As you can see, we can also specify the voltage with the slider and see what the power will be at this resistance. Below we see the recommended power.

    In addition, when the voltage changes, the application displays how the installed power will affect the vaping process; there are three options - low, optimal and overheating. It is quite convenient to know in advance in what range the coil will heat up optimally and in what range you should expect overheating and, therefore, a burning taste.

    Reprova Coil Calc also calculates the required wire length, current pi of a given power (which is very useful when vaping on mechanical mods) and the length of the coil, as well as the surface power in watts per square millimeter (this parameter, roughly speaking, gives an idea of ​​how efficiently the power will be realized by calculating the area of ​​the coil) .

    Just below there is a line with a link that you can open in the browser and all the parameters you set will be displayed in the online version, or you can send this link in a message and the recipient will also be able to see what you calculated in the application in the online version.

    You can also save your calculations inside the application, naming them as it is convenient for you (for example, in accordance with the name of the atomizer on which a specific coil is installed) and subsequently load the desired calculation at any time.

    In general, the functionality is very decent, it has everything you need and even a little more.

    Flaws:
    Among the disadvantages, it is worth noting the following points:
    • lack of calculations for complex windings such as clapton coil, fused clapton, etc.
      However, I suspect that such calculations are difficult to implement or not implementable at all, so this is rather a nitpick.
    • slightly lame localization
      Not all items are translated; there are often untranslated words in the application.
    • no version for iPad
      Sometimes it would be convenient to have such a version, for example in case there are many different saved windings, or, for example, in the iPad version it would be possible to implement different power graphs.
    • lack of calculation of the optimal temperature for nickel and titanium coils
      instead, the same power calculation is displayed depending on the resistance, which is generally not applicable in the case of nickel, which can only be used on devices with thermal control due to the very low resistivity and, as a consequence, the extremely low resistance of the finished coils
    But at the same time, I would like to note that the application is being actively updated and improved, so there is a possibility that in future versions the above shortcomings will be corrected. Otherwise the program is excellent.
    Online version:

    In general, the online version is practically no different from the mobile one, which is very convenient. However, there is one difference that, in my opinion, is quite interesting, namely the 3D temperature graph.

    I'll explain how to use it. In the photo you see three versions of this graph with the corresponding captions “little”, “good”, “bad”. This graph, roughly speaking, displays how your coil will heat up when vaping. When you change the voltage with the slider, the graph also changes. Thus, guided by its changes (and our preferences, do not forget that the calculator has only the function starting point, but not the ultimate truth regarding power selection) you can determine the voltage range for a specific spiral and your needs.

    Every vaper knows perfectly well what can be used in their serviced atomizers: both vaporizers and self-installed coils can be used. It is impossible to say which is better, since every lover of aromatic steam chooses his own “Feng Shui”. It’s worth focusing separately on self-installed coils, which you can buy in a vape shop. But sooner or later, most vapers have a desire to make their own coil, and not everyone knows about the features of coils, the specifics of their manufacture and the choice of materials.

    Materials for making spirals

    An important point for obtaining good taste and bulk when making builds is the choice of material that has the technical characteristics necessary for the vaper. Currently used:

    • Nichrome (Ni)- heats up evenly, has high plasticity, and is inexpensive;
    • Fechral or Kantal (A1)- the technical characteristics-price ratio makes it very popular among vapers, but at the same time it is not worth vaping in thermal control mode - its linear heating parameters fluctuate, and this may affect the quality of the vapor;
    • Stainless steel (SS)- a material that heats up very quickly, has minimal resistance (therefore it is worth using for mechanical mods) and can be used in TC mode;
    • Nickel- quite an expensive material, but its technical characteristics are encouraging, although there is an opinion that during operation it emits harmful substances;
    • Titanium- the material is expensive, but works great in TC mode.

    It is worth saying that when choosing a material, it is important to take into account not only its resistance in the spiral, but also the device on which it will be used.

    Types of spirals

    If you go to any search engine and type “types of coils for vaping,” you can get hundreds of options, pictures and videos with their varieties. Each of the spirals has its own characteristics, advantages and disadvantages that are worth knowing about:

    • MicroCoil- the simplest winding, which is a small spiral of wire with legs for installation. It is very simple to make - just have a wire and a drill (or any other object) of a given diameter on hand. The same coils include ParallelCoil - two wires placed in parallel, which ultimately form a single whole. Among the advantages we can note the ease of production, but you should not expect a lot of taste and steam from it;
    • Twist or “pigtail”- two wires (possibly even of different diameters) braided, which allows you to reduce the resistance of the spiral and increase the heating area. Created simply using improvised means;
    • ZIPPER COIL- these are two twists located in parallel, and the direction of the braids is towards each other (visually very reminiscent of a zipper on clothes). The coil is quite simple to make and produces an average amount of steam and flavor;
    • CLAPTON COIL- it’s worth saying right away that to make it you will need a screwdriver and two types of wire - a base (of different diameters) and a thinner one for winding onto it. The peculiarity of such a spiral is that in addition to the increased heating area, the presence of small grooves between the turns of thin wire can significantly improve the taste sensation and produce more steam;
    • FUSED CLAPTON- the basis of such a spiral is two parallel wires of the same diameter, wrapped with small diameter wire. This design allows you to get hundreds of small trays that can enhance the taste of the liquid several times. This type of spirals is one of the most common, as it is inexpensive and quite simple to make;
    • TRIPLE FUSED- the difference from a fused clapton is that the base is made of three wire strands of the same diameter. One of the best options for obtaining taste and bulk;
    • ALIEN CLAPTON- an analogue of triple fuse, but the winding is made using wire having the shape of a stretched wave, which allows you to increase the area of ​​the wrapped base of three main cores by 1.5-2 times. It has excellent flavor transfer, but requires high power to heat up;
    • STITCHED ALIEN- one of the variations of Alien, but the three veins are arranged in the form of a triangle, which has a positive effect on the taste and bulk. The spiral will delight you not only with its taste and bulk, but also with its original appearance - it won’t be a shame to post it on Instagram;
    • STAGGERED CLAPTON- one of the variations of the fuse, consisting of two claptons placed in parallel, the turns of which are slightly apart. A thin wire is wound into the resulting “slits”, which secures the claptons. Allows you to get a lot of flavor and steam, but requires quite a lot of power from the box mod;
    • Juggernaut- an analogue of a stagged one, but a parallel of two kleptons is wrapped with flat kanthal to obtain a maximum pile-up;
    • CATERPILLAR CLAPTON- four or five main pieces of wire wrapped with thinner ones. The peculiarity is that after manufacturing the spiral is tapped with a hammer to obtain a flat surface reminiscent of the tracks of the special equipment of the same name. The combination of taste and bulk is excellent, but you shouldn’t forget about the power of the box mod;
    • Green Mamba- a parallel that is wrapped with two twists located towards each other. This combination allows you to get the maximum number of microbaths and, accordingly, taste and bulk, which is why it is in demand among vapers. Suitable for drips and tanks with a large base.

    Naturally, there can be dozens of variations of coils - everything is limited only by the vaper’s imagination, his perseverance and the availability of appropriate materials. There are many combinations of the main types of coils with additional weaves to improve the basic characteristics of the coil.

    Practice shows that owners of mechanical mods should give preference to spirals made on the basis of stainless steel - their resistance is much lower than that of analogues made of kanthal or nichrome and they heat up much faster - ALIEN FOR MECHANICAL MODS or FUSED FOR MECHANICAL MODS. When using box mods, it is important to control the resistance, since not all models are capable of working with a resistance below 0.1 Ohm, but at the same time they have the ability to use complex high-power windings - STAGGERED CLAPTON COIL, ALIEN CLAPTON COIL, TRIPLE CORE ALIEN CLAPTON BY HOPPERS FACTORY, TRIPLE FUSED BY GRADE COILS, STAGGERED BY GRADE COILS or INTERLOCKING ALIEN BY GRADE COILS.
