Vape Coil Types: Best Guide for MTL, DTL & Sub-Ohm

WATT a twist of wire!

All the flavors and vapors you enjoy start from one tiny part of your vape. It all begins right inside the tank. 

At the heart of it sits the coil. The most important organ of your vape. It’s a small wire wrapped in cotton. When power hits the wire, it heats up. The cotton holds the e-juice. 

Heat turns that liquid into vapor. And you get to taste the most delish flavor! 

But vape coils aren’t all universal. They come in different shapes and resistances. Each type changes how you vape. Some give a tight draw, like a cigarette. Others produce massive clouds.

About Vape Coil

Small heater. Big job.

A vape coil is a metal heating element that stays inside your pod or tank, right in an atomizer head. That head links to both positive and negative battery terminals. That’s where the electricity flows. 

The wire resists that electricity. That resistance creates heat. Lots of it. When powered, the coil heats up and turns e-juice into vapor. Around the coil sits a wick, usually cotton or ceramic, soaked in the liquid.

The coil has 2 main jobs. 

• First, it needs to heat up fast. 
• Second, it needs to distribute that heat evenly across the cotton. 

Otherwise, there will be hot spots, which will burn the cotton. Burnt cotton tastes awful and ruins your whole day.

2 Common Coil Types

Every coil falls into one of two families based on resistance. These families match how people actually inhale vapor.

• Sub-Ohm Coils: These have a resistance under 1.0Ω. Usually between 0.15 and 0.6Ω. They need serious power, often 40 watts to over 100 watts. 

Airflow stays wide open. You pull the vapor straight into your lungs like breathing air. Direct-to-Lung or DTL-style. Massive clouds. Heavy flavor. Drinks juice like a thirsty camel.

• High Resistance Coils: They sit above 1.0Ω. Often 1.2 or 1.6Ω. They work at low power. Maybe 10 to 15 watts. 

Airflow feels tight and restricted. You pull vapor into your mouth first, hold, then inhale. Mouth-to-lung or MTL style. Mimics cigarette draw. Sips juice slowly. The battery lasts forever.

How Do Vape Coils Work?

Press. Heat. Inhale.

First, the battery detects that you pressed the button. It sends an electrical current toward the coil. 

The electricity travels through the metal threads, down the positive pin, and hits the wire. That wire hates letting electricity pass easily. So, it fights back. This creates friction, which results in heat. 

Within a split second, that wire reaches 200°C to 250°C.

The wire sits wrapped inside cotton. That cotton remains soaked in e-juice. As you take a drag, the hot wire starts cooking that liquid right off the cotton fibers. The liquid hits its boiling point and turns into tiny vapor particles. This is aerosol.

The vapor builds up around the hot coil. When you suck on the mouthpiece, you create suction. Fresh air rushes through the airflow holes at the bottom of the tank, travels past the coil, grabs all that freshly made vapor, and carries it up through the chimney tube. 

The vapor travels through the drip tip and into your mouth. Finally, you exhale a cloud. 

The whole process takes maybe half a second.

Meanwhile, the cotton keeps drinking more juice from the tank, getting ready for your next puff. As long as the cotton stays wet, the coil stays happy. 

Once the cotton runs dry, you get that horrible burnt taste that sticks in your tank forever.

6 Vape Coil Types By Structure 

1. Mesh Coils

Flat heat. Big flavor.

Mesh coils use a thin sheet of perforated metal rather than a single round wire. The sheet looks like fine netting with tiny holes. They wrap that mesh strip around the cotton. This design increases the surface area a lot. 

More surface area means more e-juice touches hot metal at once. That helps give you thicker vapor and stronger flavor.

Most mesh coils run between 0.15Ω and 0.4Ω. They work best at 40W to 80W, depending on the net size. Such coils are great for DTL vaping. Their large surface area heats rapidly and evenly, which helps maximize flavor and vapor.

The issue is that they chew through batteries faster. But for flavor chasers, the tradeoff feels worth it.

High-VG liquids perform well here. VG is thicker. Mesh spreads heat across it evenly.

• Design: Flat perforated sheet
• Performance: Instant heat, intense flavor, dense clouds
• Vape Style: DTL, Sub-ohm
• Construction: Mesh wrapped in a cotton cylinder
• Material: Kanthal, Stainless Steel, Ceramic, or Nichrome

2. Vertical Coils

Classic build. Straight airflow.

Most coils sit horizontally inside the tank. But vertical coils stand upright inside the metal casing. The wire wraps around vertically, which creates a hollow center tube. Cotton sits outside the wire. Between the wire and the metal housing. Air flows straight through the center.

This airflow path improves vapor movement. Because the air travels straight through the middle and picks up vapor from all sides of the wire. This creates less resistance when you inhale. Result: it feels smooth and steady. 

Vertical coils usually come in pre-built stock coils for tanks. They work well for both MTL and restricted direct-lung vaping, depending on the resistance.

It ranges from 0.3Ω to 1.8Ω. Lower resistance versions suit DTL. Higher ones fit MTL.

Surface area is moderate. Flavor is clean. But not super intense. Cloud size depends on coil resistance and wattage. At 1.6Ω and 12W, clouds stay small. At 0.5Ω and 30W, vapor increases.

• Design: Upright spiral wire
• Performance: Smooth airflow, consistent saturation
• Vape Style: MTL or light DTL
• Construction: Cotton wrapped outside, air tube inside
• Material: Kanthal or Stainless Steel

3. Round Wire / Spiral Coils

Simple shape. The classic. 

Round wire coils use one strand of wire wrapped around a rod into tight loops. This is the most basic coil design. Easy to produce. Easy to replace.

The wire has a circular cross-section. The simplicity means they heat up predictably. 

Surface area is limited compared to mesh or Clapton. The contact points between the wire and the cotton are small. Only the bottom of each wire loop actually touches the cotton. This means some liquid sits farther from the heat source. You get good vapor. But not maximum efficiency.

Then again, limited surface area also means controlled heating. So, good for beginners.

Resistance varies widely. High-ohm versions (1.2Ω to 1.5Ω) fit MTL devices. Small chambers, higher resistance, and lower power. Low-ohm versions (0.1Ω to 0.6Ω) work in sub-ohm tanks.

For cloud chasing, round wire falls behind newer designs. Less surface area means less vapor.

• Design: Single circular wire spiral
• Performance: Predictable heating, moderate clouds, decent flavor
• Vape Style: MTL or entry DTL
• Construction: Single wire wrapped in loops
• Material: Kanthal, Stainless Steel, or Nichrome

4. Multiple Coils (Dual or Triple)

More heads are better than one.

Same with coils. Multiple coil setups use 2, 3, or even 4 separate wire coils inside one housing. They sit side by side, each with its own cotton. All fire at the same time. 

The big benefit is that the surface area multiplies. That heats more juice per second, which leads to more cloud production. 

Dual mesh coils come in a 0.12Ω to 0.3Ω range. But they typically run at half the resistance of a single coil. For example-

Two 0.4Ω coils together give a final resistance of 0.2Ω. This lets you push serious power. Often 80 to 150 watts. As a result, you get massive clouds.

However, more coils need more power. And this drains the battery faster. Not just that. Multiple heating elements also need more airflow to cool them down. If airflow can’t keep up, the vape can get harsh. 

Such coils work best for experienced vapers and cloud chasers. 

• Design: Multiple separate wire coils
• Performance: Massive vapor, warm dense hit, intense flavor
• Vape Style: High-power DTL
• Construction: Coils parallel, shared airflow
• Material: Kanthal, Stainless Steel, Ceramic, or Nichrome

5. Twisted Coils

Twist for texture.

Take 2 or 3 strands of wire. Twist them together like rope. Now, wrap that twisted rope into a coil. That’s a twisted coil. The design helps increase surface grooves. Those grooves trap little pockets of e-juice. 

When the wire heats up, the trapped pockets vaporize right on the wire surface. This gives you a stronger flavor. It means you get to relish every note. 

Twisted wires also increase surface area without making the coil physically bigger. The ridges and valleys add extra metal surface. This helps increase vapor production. 

Ramp-up time feels slightly slower than simple round wire. It’s because more metal mass needs heating. But once hot, they hold temperature steady. 

Resistance usually falls below 1Ω, depending on wire gauge. Good for medium-power vaping around 40 to 60 watts. The flavor improvement over standard round wire is noticeable, especially with fruity e-liquids.

• Design: Twisted strands wrapped into a coil.
• Performance: Rich flavor, thicker vapor
• Vape Style: Mid-power DTL
• Construction: Multiple strands twisted together
• Material: Kanthal, Nichrome, or Stainless Steel

6. Clapton / Fused Clapton Coils

Named after the guitarist Eric Clapton.

It’s because they look like guitar strings. Clapton coils have a thick core wire wrapped in a thinner outer wire. The core carries the electricity and heat. The outer wrap adds surface area and texture without massively lowering resistance.

The outer wrap creates tiny gaps along the coil. These gaps hold the juices against the heat source. That way, flavor feels layered and deeper. And vapor becomes denser. 

Fused Claptons take this further. Rather than one core wire, they use 2 or 3 cores side by side. All wrapped together with the thin outer wire. This doubles or triples the core mass. Result: more surface, more vapor, and faster heating. It’s because the electricity travels through multiple paths. 

Fused versions heat faster than single Clapton because of better current flow.

These coils are popular in rebuildable tanks and drippers. They need power, usually 12 to 100 watts, based on size. Common resistance ranges from 0.1Ω to 0.8Ω. 

The only downside is the ramp-up time due to extra metal mass. 

• Design: Core wire wrapped in thinner wire
• Performance: Deep flavor, thick clouds
• Vape Style: Advanced DTL
• Construction: Multiple cores with outer wrap
• Material: Kanthal, Nichrome, or Stainless Steel

5 Vape Coil Types By Material

1. Kanthal Coils

Old favorite. Steady heat.

Kanthal is an alloy of iron, chromium, and aluminum. It handles high heat well. That makes it durable. 

Resistant doesn’t shift, and materials don’t melt even after repeated heating. So, you get predictable performance from the Kanthal Wire. And since resistance stays stable or flat, it doesn’t support temperature control mode. 

Rather, it works only in wattage mode. At 10 watts or 100 watts. So, you set your watts and vape only. Simple. 

Ramp-up feels moderate. Not too fast. Not too slow.

Flavor is neutral.  It doesn't add any taste to your e-liquid. Vapor production depends more on structure than material here.

• Material: Iron-chromium-aluminum alloy
• Performance: Stable resistance, wattage only
• Vape Style: Any
• Other Names: FeCrAl alloy

2. Stainless Steel Coils

Flexible choice. Dual mode ready.

Stainless steel works in both wattage and temperature control modes. That makes it versatile. It comes from steel with chromium added to prevent rust. 

Although the material comes in different grades, S316 is common in vaping. 

It heats faster than Kanthal. And you can call it the multi-tool of coil materials.

The resistance increases slightly as it heats. This lets temperature control mods calculate wire temperature accurately.

Ramp-up feels quick in wattage mode. You get quicker vapor production. The flavor is slightly brighter than Kanthal. Some say cleaner. Clouds are similar.

Good for both MTL and DTL depending on the build.

The downside? Softer than Kanthal. SS bends more easily. And this can make building trickier. It can also get hot spots if not installed perfectly. 

• Material: Steel-chromium alloy
• Performance: Fast ramp-up, TC compatible
• Vape Style: All styles, very versatile
• Other Names: SS304, SS316, SS316L

3. Nichrome Coils

Fast heat. Quick hit.

Nichrome contains nickel and chromium. It has lower resistance than Kanthal. That means faster heating at the same wattage. You press the button, and vapor comes instantly. No waiting.

The lower resistance per foot lets you build coils with more wraps while staying at moderate resistance. More wraps give you more surface area without crazy high power.

Ramp-up feels almost instant. That gives quicker vapor production. Good for short puffs.

Nichrome works only in wattage mode. The resistance curve isn't consistent enough for accurate temperature control.

Flavor feels slightly sharper as heat builds quickly. Some vapers feel it gives a slightly more pronounced flavor than Kanthal. Several sub-ohm coils use Nichrome for faster response.

• Material: Nickel-chromium alloy
• Performance: Extremely fast heating
• Vape Style: DTL, Sub-Ohm
• Other Names: Ni80, Ni90

4. Nickel Coils

Soft metal. 

Nickel wires basically started the TC revolution. So, they work only in temperature control mode. 

It has very low resistance. Small coils can measure 0.1Ω or lower. Its resistance changes dramatically and predictably as it heats. Mods read that resistance change and calculate the exact wire temperature. That helps prevent dry hits.

However, nickel feels soft and is hard to shape evenly. That’s why it’s not common in prebuilt coils now. Even if your device uses one, never fire it in wattage mode. Otherwise, the mod would dump full power into that low resistance, and this would lead to 2 consequences. Overheating. Toxic Fumes. 

The flavor from nickel is fine. Nothing special. 

• Material: Pure nickel wire
• Performance: Accurate TC, very low resistance
• Vape Style: Temperature control only
• Other Names: Ni200

5. Titanium Coils

Light metal. Smooth heat.

Titanium sits between nickel and stainless steel. It offers accurate temperature control. But with better structure and strength. The big plus is that such a wire holds its shape during building. No floppy noodles here.

The resistance of titanium is higher than that of nickel. So, you can build coils with more wraps (while staying in the TC range). Result: Bigger surface area. Better flavor.

Big warning though: Never pulse titanium coils to check for hot spots. When titanium gets red hot (in the presence of oxygen), it forms titanium dioxide. This white powder can be harmful to inhale. 

• Material: Pure titanium wire
• Performance: Accurate TC, good structure
• Vape Style: Temperature control only
• Other Names: Grade 1 titanium

FAQs

Is a 1.2 or 0.8 coil better?

A 1.2Ω coil is better for a tight, cigarette-like mouth-to-lung draw and uses less power. A 0.8Ω coil offers a slightly looser draw with a bit more vapor. This makes it a great middle ground for restricted lung hits.

Which vape coil is best?

Mesh coils are widely considered the best for flavor. It’s because their flat surface heats e-juice evenly and instantly. For massive clouds, a dual or fused Clapton coil running at high wattage is the top performer. Find best vape coils at VapeDeal. 

What are the different types of vape coils?

Coils are grouped by structure (mesh or Clapton )and by material (Kanthal or Stainless Steel). Your choice depends on vape style: MTL (high-resistance round wire) or DTL (low-resistance mesh for flavor or multi-coils for clouds).

Which vape has the best coils?

There isn't one single best vape. But look for devices compatible with popular coil families. Try tanks with mesh coil technology, usually ranging from 0.15Ω to 0.2Ω for DTL. They consistently deliver the best flavor and cloud balance right now.
