Understanding Vaping Coil Wire Basics (2023)

Understanding Vaping Coil Wire Basics (1)If you’re happily vaping along with a premium yet simplistic vape kit that’s easy to set up and use, this guide isn’t essential reading. Nevertheless, whatever your stage is in the vaping journey, knowing the basics such as the different vaping coil materials and each unique quality they possess is useful. If you’re interested in rebuilding your atomiser and all that they can do for you, these basics are a must. After all, any vapour device we use will have one.

The Purpose of a Vape Coil Wire

A vape coil wire plays a very important role in your overall experience. It will form the coil, which works to build up the heat with the help of your battery and transmit them to your wick so it can be heated. Once your wick soaked with e-liquid is heated, then that lovely vapour will be produced. It’s not just central to your atomiser but how your vape will operate too.

Gauge and Resistance - the Key Terminology Explained

Before we go on to discussing the different types of coil wire, there are some terms you should understand. The first is the gauge, which is simply the diameter and thickness of the wire. A higher gauge number will mean a thinner wire and smaller diameter. Typically coil wire is somewhere between 22 and 32 gauge.

Resistance, measured in Ohms is equally important. As the size of your wire goes up, the wire’s resistance decreases. Therefore, a thinner wire with a 30 gauge will have more resistance but will also heat up quicker than a 22 gauge wire. A thicker wire creates less electrical resistance because more current will pass through.

Lastly, you should know what ramp time is. This is the time it takes for your coil to reach the minimum temperature needed for vaporising your e-liquid. With a bigger mass, you’ll see a lower gauge number which takes longer to heat up. For a quicker ramp-up time, thinner wire is the best choice.

Best Wire Type for Vaping

Different types of coil wire will behave differently to electricity and heat, and thus will have their own sets of pros and cons. Let’s take a look at the four most popular types and what each can offer you.

  1. Kanthal – As one of the most widely available types of coil wire, Kanthal is extremely popular. Easy to acquire, it’s also cheap and often the starting point for anyone trying to build their coil. It's a little slow in ramp-up time but still very popular with vapers.
  2. Stainless Steel – In contrast to Kanthal, using stainless steel provides a very quick ramp time. It’s also one of the easiest wire types to manipulate and create shapes, with a stronger hold. The potential nickel content (which is very low) creates a dilemma for a small group of vapers, due to potential allergies as explained here by the NHS.
  3. Titanium – This is one of the least used of the four that we have covered. Titanium does have some strong points. It is really simple to work with and it does a great job in combination with most wicking material. Yet, there are concerns. Titanium is known to release a toxic compound at extremely high temperature and it is hard to put out if for some reason it did catch fire. This isn’t a concern for the people that use it and swear by it, but it’s enough to make most people opt for Kanthal or stainless steel instead.
  4. Nichrome – This type of wire is an alloy made of nickel and chromium. The points in favour of using nichrome (NiCh) are that it holds its shape well, and it can ramp up quickly. On the downside, it’s that it isn’t so easy to find, so you’ll probably have to search online to get it.

Is Mesh Coil Better Than Standard Wiring?

In the past, every coil was shaped the traditional way, wrapped around the wick. However, in more recent times we have seen the emergence of the mesh coil, which enhances the flavour and boosts the temperature at a quicker rate due to a larger surface area. This coupled with the perforated holes and unique style started by Freemax is now a popular trend with Sub-Ohm vapers using high VG e-liquid.

Important Consideration - Temperature Control

Vaping is about fine-tuning your experience to get the right hit from your device. With so many finer points to iron out, coils are only one part of the equation. You have to consider how many watts you want to vape at, the flavour consistency expected from your coils - even the sort of cloud production you want. The mode or settings you adjust will also play a part. For instance, many beginner and advanced vapers alike question whether temperature control (TC) is the way to go, or your vape should be tailored towards adjustable wattage.

Before choosing which route to go down, it’s important to understand that not all coil wire types are compatible with the various modes vape mods offer. To break it down:

  1. Coil wires such as nickel and titanium do not work in wattage mode but are compatible with temperature control mods. This is because they offer a vape wire that increases in resistance. The advantage of NiCh and stainless steel, which is explained in more depth below, is the greater protection of your cotton. It will not burn if you are low on e-liquid in TC mode with these two coil wire types.
  2. In contrast, Kanthal and nichrome do not work in TC mode. Because they operate on a static current, this makes increasing the heat a real challenge, increasing the chances of your coils burning out or even overloading. However, they work perfectly fine in adjustable wattage mode.

For those vapers still tossing and turning at night, unsure which option to go for, stainless steel is the safe choice. With stainless steel, you’ve got a jack of all trades that ticks both boxes, working for not just adjustable wattage mods but temperature control too.


Which Vape Coil Wire is Best for Flavour?

Although nichrome should be avoided if you have a nickel allergy and to an extent stainless steel vape wires, for flavour alone lots of vapers believe these two types offer the best flavour for vaping. Even more so than Kanthal, which tends to be the popular choice for price and durability. Overall, it depends on whether you want quantity or quality. A lot of vaping is trial and error - adjusting your device, e-liquids and set up to find the perfect match.

Pre-Build Coils vs Build Your Own - Verdict

Now that you know the basics of coils; including their function, the different types and how they work in various modes, you should have enough knowledge to take your vaping experience to the next level. For those who Sub-Ohm vape, you already have a lot to think about to get the best results. When you want to maximise the performance of your vape on the go, the main considerations include how to get the largest cloud production and enhancing the flavour as much as possible. Some vapers choose to do so manually themselves, but this requires a greater effort and additional time. To do so, you’ll need the following:


  • Scissors to cut the wicking material (often cotton) in a neat manner
  • Tweezers to test the coil resistance safely, known as ‘pulsing’
  • Your wire of choice
  • Wire cutters
  • A screwdriver or metal tool to shape and tighten the coils and bolts holding the coils in place

While building your coils has a couple of advantages, giving you greater control over customising the vaping mod you select at a slightly cheaper price, most still opt for pre-built coils. The main reasons for this include:

  1. Easier to use, simply slotting the Sub-Ohm coil into your vape mod or already installed in some vape pod kits for MTL vapers.
  2. No need to fiddle about with components and wires.
  3. Fewer parts to buy and do not need to source each aspect individually.
  4. The likes of SMOK, Innokin and Aspire produce a great range of stylish and easy-to-use coils.

The team at V2 Cigs is happy to help with any queries you have found the perfect coil to slot in your vape. Whether it’s Kanthal coil wire for longevity or stainless steel for versatility, there is something out there for every flavour preference when you vape.


How do I know what wire to use for vaping? ›

Wire gauge: a brief rundown

Vapers usually use 22, 24, 26, 28, 30, and 32 gauge wire. The bigger the number of the gauge increases, the thinner the wire gets. For instance, a 24 gauge wire at about 0.02 inches, that is 0.51 mm in diameter, while a 30 gauge wire falls at 0.01 inches, 0.25 mm in diameter.

What is the difference between 0.8 and 1.2 coil? ›

The 0.8ohms are a restricted direct to lung (RDL) coil type, meaning they are able to be used with a wide range of e liquids. The 1.2ohms are for a mouth to lung (MTL) vaping experience, which replicates the feel of a smoke on a cigarette.

What do the numbers on a vape coil mean? ›

Some of the more common ohms are 1.5, 1.6, 1.8, 2.1, 2.2, and 2.5 ohms. What do those numbers mean for you the vapor? General rule of thumb is the lower the ohm(lower the number) the harder the hit, more vapor, warmer the vape, and shorter the battery life before recharging.

What is the difference between a 0.6 and 1.2 coil? ›

The 0.6ohm coil is perfect for hybrid sub vaping that want more clouds and low nicotine dosage. The new 1.2ohm coil is for true mouth to lung vaping and perfect for high nicotine dosage without flavourloss.

What ohm coil is best for flavor? ›

Coils With a Rating At 1.0 Ohm or Above

Coils with at least 1.0 ohm resistance are designed for 'mouth-to-lung' vaping. They produce a subtle, cool vapour with intense flavour.

What wire is best for flavor? ›

Stainless steel, on the other hand, heats up faster, lasts longer, and delivers better flavor than kanthal. While there's nothing wrong with using nickel, nichrome, or titanium coils, just be sure you know what you're doing first.

Is 1.0 or 0.8 coil better? ›

The 0.8ohm coil is best when used at a wattage of between 20w-35w. We recommend using nicotine salts with his coil for the ultimate experience. The standard 1.0ohm coil is also great for MTL vaping, however, offers more resistance for a deeper mouth to lung experience.

Does higher ohms mean more vapor? ›

Higher Ohm Coils

Produce less vapour due to there being less heat at the source (the coils).

What coil should I use for 50 50? ›

The resistance of a coil is given in ohms. As a rule of thumb: if your coil has a resistance of 1 ohm or above, use 50/50 PG/VG e-liquids or liquids with more PG than VG. if your coil has a resistance under 1 ohm, use e-liquids with more VG than PG.

What's the difference between 0.6 and 1.4 coil? ›

The 0.6Ω mesh coil is specially designed for sub-ohm vaping, it has a large mesh inside, with which you can get faster heating process and massive vapour clouds; and the 1.4Ω regular coil is designed for MTL vaping, you can enjoy throat hit with it.

Is it better to have higher ohms or lower vape? ›

Simply put, ohms is a measure of electrical resistance or how freely electricity is able to travel. Lower ohms will produce more heat and this will affect vapor production, throat hit, temperature of vapor and flavor. At an experiential level, LOWER OHMS: Will run hotter, producing a warmer vapor.

What wattage should I vape for beginners? ›

If you're just getting into vaping, starting with a low wattage, around 7 watts may be best.

Is 1.2 ohm good for salt Nic? ›

If you're using a coil that's around 1.0ohm to 1.2ohms you'll get a decent nicotine hit and great flavour. For smokers getting through 5 to 10 cigarettes a day: You're still a “moderate smoker” at this level and something like a 6mg or 10mg will work for you too.

What is a 0.8 coil for? ›

The Eleaf 0.8ohm GTL coil is a sub-ohm atomizer designed for vaping at lower wattage outputs, mimicking the sensation of smoking.

Is 0.4 or 0.2 coil better? ›

The lower resistance 0.2 ohm coils allow higher wattage to be used. This said, in this case, the 0.4 ohm coils give much better flavour with the Cleito tank than the 0.2 ohm coils.

Does higher ohms mean more flavor? ›

Lower resistance coils produce more flavour, vapour and heat at a lower voltage than higher ohm coils because they use more watts. For example, if you have a 1.8ohm coil running on 3.7 volts you'll get an output of around 7.3 watts.

Does lower ohm mean more flavour? ›

Low ohm vape coils produce more vapour and flavour and case use more e-liquid and take more battery power than high ohms. High ohm e-cig coils produce less vapour and use less e-liquid and battery.

Does more airflow use more juice? ›

A higher airflow will ensure a cooler cloud, but when you cool it down, you will lose a bit of flavour. Because of this, a higher airflow can decrease the amount of juice required, because it remains on the coils for longer.

Is it better to use thicker wire? ›

The thin wire will conduct electricity, but there is more electrical resistance. The thicker wire is like the four lane highway. There's a lot less electrical resistance, and as a result, that light bulb burns brighter because more electricity can reach it.

What are the 4 types of wire? ›

Types of Wire - A Thomas Buying Guide

While the exact duration may differ from person to person depending on their personal vaping habits, most new coils are designed to last anywhere between 7 to 21 days. This varies depending on how well you care for and clean your device.

How do I make my vape clouds bigger? ›

Try leaning forward slightly and straightening back up as you inhale. Straightening up while inhaling naturally opens up the lungs and allows more vapour to enter them. While exhaling, try pushing out your lower jaw slightly.

What wattage should I vape at 0.6 ohm? ›

In contrast, the 0.6ohm coils have a recommended wattage of 12-25 watts. They are therefore classed as restricted direct to lung (RDL) coils, offering less clouds but conserving your battery and e juice.

Do lower ohm coils burn out faster? ›

Sub-ohm coils heat up much quicker than those with a higher resistance. If your e-liquid has a thinner consistency then the atomizer head can vaporize it too quickly, causing premature burning.

What is the difference between 0.6 and 0.8 coil? ›

If you want a bit more flavor and juice with a bit less nicotine but still want a MTL draw, you can use the 0.8 ohm mesh coil. If you're chasing clouds, the 0.6 ohm mesh coil offers some impressive cloud production for a pod vape and wicks fast enough to handle thicker vape juice.

What does 70 PG 30 VG mean? ›

An e-liquid with a VG:PG of 70:30 will contain 70% vegetable glycerine and 30% propylene glycol.

What coil is best for 70/30 Juice? ›

As a general rule of thumb, Sub Ohm coils should only be used with E Liquids in a 70% VG to 30% PG mix since VG is much thicker than PG. The low power resistance allows for much higher temperatures to be used, meaning more E Liquid can be vaporized in one go.

Does higher wattage give more flavor? ›

Flavor. Wattage for sure can impact flavor, as higher wattages can produce a stronger flavor. That can be a good or bad thing depending on your tastes and the flavor of the e-liquid itself.

What juice is best for 0.6 ohm coil? ›

For 0.8/0.6Ω coils start with 60% VG or 70% VG and use that as a guide. For 0.5Ω coils start with 70% VG and use that as a guide. Just try a small amount until you know how your coil/device is performing with your particular juice flavour/blend.

What wattage is best for salt nic? ›

What's the Best Wattage for Nic Salts? It's key to not go too high in terms of wattage for your nic salts. Keep it lower than 15 watts and you will have a premium vaping experience with your chosen nic salts. Anything higher than that could cause a sharp throat hit and loss of flavour.

What is the safest ohms for vape? ›

But to ensure that you remain safe, build a bit higher; 0.12ohm would be better to ensure that you're vaping safely within the limits of your batteries and not stressing them. NOTE: A single coil with a resistance of at least 0.11ohm is safe for the build above.

What wattage should I vape at 0.4 ohm? ›

Ideal at 12 watts. RPM Mesh 0.40Ω Coil, mesh resistance, for increased heating speed, will be ideal at 25 watts.

Is 1.2 or 0.8 ohm better? ›

The higher the resistance, the cooler and weaker the vape, but that's not necessarily a bad thing. The 1.2-ohm coil is great for stronger salts, while the 1.0-ohm coil is perfect for mid-strength juices. The 0.8-ohm coil is the best for flavor in my opinion and needs less nicotine to shine.

What airflow should I vape at? ›

Most vapers find a 'happy medium' airflow setting, where the vapour is a comfortable temperature, they can still taste the vapour and they're happy with the size of their vape cloud.

Why does my vape burn my throat? ›

Strength of Liquid is Too High

When we vape we experience what's known as a “throat hit” which is basically the feeling you get in your throat when you inhale. The severity of the throat hit depends on the strength of your liquid – the stronger the liquid the more intense the throat hit.

What voltage should I set my vape too? ›

What Is the Best Volt Setting for My Vape Pen? The most common range for a variable voltage vape pen is between 3.3 volts and 4.8 volts.

Why is my salt nic harsh? ›

Nicotine is too strong

Perhaps the most common cause for a harsh vape is the strength of nicotine is too high. This is an easy mistake to make, particularly if you're just starting out on your vaping journey, and switching up your e-liquid for one that contains less nicotine should swiftly resolve the issue.

What is 20mg nic salt equivalent to cigarettes? ›

A disposable vape with a 2ml tank (the legal max size in the UK) with a 20mg nicotine or Nic Salt, contains 40mg of nicotine in the entire disposable (2ml x 20mg). This is why most disposables are suggested to be the equivalent of a pack of 20 cigarettes.

Is .8 coil good for salt nic? ›

Given that nic salts absorb so quickly into your system, if you're using a 20mg nic salt for example, we'd recommend using the higher resistance coils. Anything between 1.2ohm to 1.8ohm is great, they'll give you a smooth hit, the right amount of nicotine and won't be too potent to enjoy.

What's the difference between 0.8 mesh and 1.2 mesh? ›

They are both suitable for MTL (mouth-to-lung), which is very rare, with the only difference being that the 0.8Ω puts out warmer vapor than the 1.2Ω coil.

Is 0.6 or 0.4 coil better? ›

Neither is “better” nor “best,” it's strictly a matter of personal taste… and there is so little difference in those, there won't be any difference in how it vapes, though lower resistance will run down the battery faster.

Which coil is mouth to lung? ›

What Coil Resistance (Ohms) Should I Use For Mouth To Lung (MTL) Vaping? For MTL, coils range from 0.6Ohm-2.8Ohm. The most common coils for MTL vaping are 0.6Ohm and 1.8Ohm.

Does higher wattage burn coil? ›

Choose a lower wattage

If you prefer high wattage, make peace with the fact you'll go through your coil faster than a vaper who chooses a lower wattage.

What juice is best for 0.4 ohm coil? ›

Coils of 0.4 ohm and lower

The amount of VG will usually need to be anything from 50% VG, and in some cases the user's preference is 100% VG.

The EF 0.3ohm Coil is rated at 30-60W, allowing a great vaping experience with thicker vapor clouds.

Can I use any wire for vape coil? ›

Can I use any type of metal wire to repair the coils in vape modes? No you can't use any type of wire, the most common is kanthal, stainless steel and nichrome.

What kind of wire is used for vape coils? ›

Stainless Steel Wire

It is also durable, flexible, easy to use, and stainless steel holds its shape very well. Stainless steel wires come in a large assortment of suitable grades for building vape coils (with the specific grade determining how difficult it is to work with.

What color wires do I use to hit my cart? ›

Remember that you only need the positive and negative leads within the wire, which are usually labeled black and white. The positive (black) wire fits snugly and conveniently inside the small hole in the bottom of your cartridge, and the red wire rests lightly on the outside metal threading.

Does coiled wire increase voltage? ›

The induced voltage can be increased by winding the wire into a coil because the field lines intersect the circuit multiple times. The direction of the magnetic field produced by a coil can be determined by the right hand grip rule.

Which is better kanthal or Nichrome? ›

Kanthal is superior than Nichrome in terms of functionality and service life therefore it is recommended as a standard alloy for heating elements for use in the industrial furnaces. The essential benefits obtained from kanthal heating wire are higher maximum temperature limit of 1425 °C or 2280 °F with extended life.

Is lower ohms better for vaping? ›

Lower ohms will produce more heat and this will affect vapor production, throat hit, temperature of vapor and flavor. At an experiential level, LOWER OHMS: Will run hotter, producing a warmer vapor.

Which wire is hot smooth or ribbed? ›

The ribbed side of the line cord indicates the neutral wire, the smooth side, the hot wire. If we are wiring a line cord plug, the ribbed wire would connect to the wider space or neutral space on the plug itself.

Which wire is positive smooth or ribbed? ›

Ribbed is the neutral (negative) side and smooth is the line (positive).

Is coiled wire is better? ›

Coiled wires (also called retractile cords) are great for keeping long wires tidy and together. Their springy nature allows them to be stretched and then return to their coiled shape, keeping your wire localized and neat looking.

Why is coiled wire better? ›

Because of the special process by which the cords are coiled, the wires can stretch and retract as needed without undue wear on the wires held inside. Coil cords are found in many different industries and can be made to almost any kind of required specification.

Which is better kanthal or Clapton? ›

Clapton coils are usually made from Kanthal and it's all about the style of the coil winding. Claptons are more complex from the wiring point of view and have a wider area of wiring. As this means more contact with the e-juice, it can also vaporise it better, being more efficient.

What color wires go to what? ›

Black wires are hot wires that run to the electrical outlet from the switch. Red wires are hot wires common in a 240-volt outlet or when a wall switch controls the outlet. Blue and yellow wires are hot wires for ceiling fans and three- or four-way switches. White or gray electrical wires are neutral wires.

Which wire is hit the white or black? ›

The black wire is the "hot" wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the "neutral" wire, it takes any unused electricity and current and sends it back to the breaker panel.
