SMOK Coil is the general name for the replaceable coil families used in SMOK brand electronic cigarettes, pods, pod mods, and atomizer systems. Over the years, SMOK has developed numerous different coil platforms, ranging from low-power MTL coils to high-power DTL tanks.
SMOK coil varieties include distinct systems such as RPM, RPM 2, RPM 3, RPM 4, LP1, LP2, Nord, D-Coil, TA Coil, TFV18, TFV16, and V18 Mini. These coil families differ in physical dimensions, connections, resistance, wattage ratings, and compatible tanks or cartridges.
Therefore, when purchasing a SMOK coil, it is not enough to look only at resistance values like 0.15Ω, 0.4Ω, 0.6Ω, or 0.8Ω. You must first check which coil family your device, pod, or tank supports.
The shortest answer to the question "What is a SMOK coil?" is that it is a replaceable consumable part that heats the e-liquid inside a SMOK tank or pod system.
A ready-made SMOK coil generally contains;
When the device is fired, electricity from the battery heats the coil. The e-liquid carried by the cotton is heated to produce an aerosol.
You can browse the Electronic Cigarette Coil category for options from different brands.
SMOK RPM Coil is one of the brand's broadest legacy pod coil platforms.
The RPM family has seen various coil options developed over time, including;
This wide resistance range has made the RPM coil family a preferred choice for both MTL and more open pod usage.
RPM Mesh 0.4Ω is one of the most common options in the RPM coil family.
It has been used in the RPM40, the RPM Pod within the RPM 4, the RPM cartridge for the Nord 2, and various other RPM-compatible devices.
However, using a different cartridge on the same device may change the required coil family.
No. Some SMOK devices have used two different pod options on the same body.
For example, the Nord 2 offers;
Uses the RPM Coil family.
Uses the Nord Coil family.
Even if the device name is the same, the cartridge used can change the correct coil selection.
RPM 2 Coil is a coil family with a physical structure distinct from the classic RPM Coil.
The RPM 2 platform includes;
options.
RPM Coils and RPM 2 Coils are not compatible with each other. Despite the similarity in name, their physical coil platforms are different.
The RPM 2 Mesh 0.16Ω coil is developed for low-resistance DL usage.
In the technical specifications for the SMOK RPM 85 / RPM 100, the RPM 2 0.16Ω coil is listed with a range of 25–50W, with an optimum power of approximately 40W.
The RPM 2 DC 0.6Ω Coil is one of the options geared toward MTL usage.
Technical specifications specify a power range of 12–25W for this coil.
RPM 3 Coil is the coil platform used in high-power SMOK devices such as the RPM 5, RPM 5 Pro, RPM 85, and RPM 100.
40–80W
20–45W
Both coils are in the low-resistance usage category, but their wattage ranges differ significantly.
The RPM 3 Meshed 0.15Ω coil has an operating range of 40–80W.
It is the higher-power coil option in the RPM 3 family.
The manufacturer specifies an operating range of 20–45W for the RPM 3 Meshed 0.23Ω coil.
New coil options under the RPM 4 name have also started to be used in SMOK's newer products.
Specifically, the RPM 4 Meshed 0.6Ω Coil is one of the coil options added to SMOK's current product records as of late 2025.
Therefore, the terms "RPM Coil used by the RPM 4 device" and "RPM 4 Series Coil" should not be confused.
Important name distinction: The original RPM 4 Kit was offered with two different pods capable of using both RPM Mesh 0.4Ω and LP2 coils. The new "RPM 4 Meshed 0.6Ω Coil" is a separate coil product name.
LP1 Coil is the SMOK coil family used in more compact pod systems like the Novo 4.
SMOK's current coil compatibility list includes;
various options.
The LP1 family consists mainly of options for MTL and low-power pod usage.
The inclusion of resistances such as 0.8Ω, 0.9Ω, and 1.2Ω distinguishes this platform from high-power SMOK DTL coils.
LP2 Coil is a different coil platform that offers lower resistance and wider power options compared to the LP1.
The LP2 coil family includes options such as;
The G-PRIV Pod and the LP2 cartridge of the RPM 4 are examples of products using this coil system.
No.
A higher-resistance, MTL-focused compact pod system.
A different platform with more open DL/RDL usage options via 0.23Ω, 0.4Ω, and 0.6Ω.
The physical connections of the two coil families are not the same.
Nord Coil is one of SMOK's longest-serving coil platforms.
Over the years, the Nord family has seen the development of various coil options, such as;
No.
Nord and RPM are entirely different coil families.
Because some devices offer two different cartridge options, both Nord and RPM coils can be used on the same device body, but a coil cannot be swapped directly into the same pod.
SMOK D-Coil is one of the new-generation low-resistance coil platforms used in the TF-D Sub-Ohm Tank and current DTL systems.
There are different resistance options in the D-Coil family.
The D-Coil Meshed 0.15Ω is one of the options used in the current X-PRIV SOLO + TF-D Tank system.
The recommended operating range by the manufacturer is 55–65W.
The D-Coil Meshed 0.23Ω coil is used in the 45–55W operating range.
D-Coil is the TF-D Sub-Ohm Tank coil platform.
For example, the X-PRIV SOLO kit offers 0.15Ω and 0.23Ω D-Coil options along with the TF-D tank.
D-Coils are not the same as RPM, LP, or TA Coils. Being a SMOK brand does not guarantee physical compatibility.
SMOK TA Coil is a low-resistance coil platform used with the T-Air Subtank and specific Nord GT systems.
The TA family includes options such as;
The TA Coil is primarily considered in the more open RDL/DTL usage category.
No.
TA Coils and D-Coils are physically different coil systems produced for separate tank platforms.
Even if their resistance values are similar, they should not be used interchangeably.
TFV18 Coil is the coil family developed by SMOK for its high-power TFV18 Sub-Ohm Tank system.
Key TFV18 coil options include;
TFV18 coils are products geared toward much larger tanks and higher power classes than classic pod coil platforms.
No.
Coil family used for the full-size TFV18 Tank.
A physically different coil family produced for the TFV18 Mini Tank.
These two products can often be confused due to name similarity.
The V18 Mini Coil is the coil series used for the TFV18 Mini tank.
This family includes options such as;
Products like the Fortis Kit and R-KISS 2 have used the TFV18 Mini Tank.
TFV16 Coil is the coil platform belonging to the high-power TFV16 Tank family.
The TFV16 options include various high-power coil structures, such as;
TFV16 and TFV16 Lite should be considered different coil platforms.
On the TFV16 Lite side, there are separate coil options such as;
There is a very wide resistance range in the SMOK coil family.
These values are a general classification. The usage method should not be determined solely by the ohm value.
No.
There are many different coil families in the SMOK product range that use the same resistance value.
For example, at 0.6Ω resistance, there are completely different products such as;
Seeing "0.6Ω" written does not mean compatibility. The coil family must be checked.
No.
Resistance is an electrical characteristic of the coil but does not determine the operating power on its own.
Heating surface, coil structure, mesh technology, and physical size can change the required wattage.
Therefore, the wattage range indicated on the coil or in SMOK technical information should be used.
There is no single wattage value for a SMOK coil.
The brand's product range extends from low-power MTL coils to high-power DTL tank coils.
For example;
Maximum device power is not the power at which the coil will be used. If a 45–55W coil is used on a 100W device, you must stay within the coil's own wattage range.
SMOK coil systems have different options for MTL, RDL, and DTL usage.
However, the usage character should be evaluated along with tank airflow and device power.
Mesh Coil is a coil technology that uses a wider surface area, net-like heating element instead of a classic round wire.
Nowadays, mesh options are available in most SMOK coil families.
For example, there are different mesh platforms such as;
The term "mesh" alone does not mean MTL or DTL.
Dual Mesh is one of the coil technologies that uses a double-mesh heating structure within the coil.
SMOK has different Dual Mesh options across its different generations;
Although these products all bear the name Dual Mesh, they are not physically compatible with each other.
The following order can be followed when choosing the right SMOK coil:
No.
For SMOK brand devices, just looking at the series name is not always sufficient.
Especially in the Nord and RPM series, different cartridges may have been offered for the same device.
For example, the RPM 4;
has been offered with two different pod/coil systems.
The classic RPM 4 device uses two different pods:
RPM Coil family, includes RPM Mesh 0.4Ω in the kit.
LP2 Coil family, includes LP2 Meshed 0.23Ω in the kit.
Therefore, when searching for an "RPM 4 coil," you must first check which cartridge is currently installed on the device.
The Nord 2 is also a device that can be used with two different cartridge systems.
It uses Nord Pods with Nord Coils, and RPM Pods with RPM Coils.
An incorrect pod-coil match will not be physically compatible.
The primary pod system for the RPM 85 and RPM 100 devices uses the RPM 3 Coil family.
The standard kit includes 0.15Ω and 0.23Ω RPM 3 Meshed coil options.
The SMOK X-PRIV SOLO kit uses the TF-D Sub-Ohm Tank.
This tank works with D-Coil options such as;
After a new SMOK coil is installed, the cotton inside must be completely saturated with e-liquid before the first use.
SMOK calls this process coil priming.
SMOK's official coil priming guide suggests;
Waiting time for SMOK products can vary in different instructions depending on the device and coil system.
While some SMOK pod device manuals specify 2–3 minutes, the general SMOK coil priming guide suggests 5–10 minutes, and some tank manuals recommend 15 minutes for complete saturation.
Therefore, it is not correct to give a single fixed minute value for all SMOK coils. The basic rule is to ensure the coil cotton is fully saturated with e-liquid and to follow the user manual for the specific device.
Priming is the process of completely saturating the cotton inside a new coil with e-liquid before its first use.
Firing a new coil while dry can cause the cotton to burn and create a persistent burnt taste.
In systems with adjustable wattage, starting the first few puffs at a lower wattage than the normal operating level is preferred.
According to SMOK technical support, reasons for an early burnt taste include;
Dry Hit is the dry and burnt taste that occurs when the coil is fired while the cotton inside is not carrying enough e-liquid.
Dry Hit can be caused by;
It is not correct to give a fixed number of days for SMOK Coil lifespan.
Coil lifespan can be affected by;
Symptoms that may indicate the coil's useful life is nearing its end include;
Ready-made SMOK coils are consumable parts where the cotton and heating system are contained together within a metal housing.
A ready-made coil that has completed its lifespan is not designed to be re-wicked in standard use.
In case of a persistent burnt taste or significant performance loss, a compatible new coil is used.
The maintenance and rebuildable structure of RBA systems are different from ready-made coils.
In addition to ready-made coil options, RBA structures are offered in some legacy and current SMOK coil platforms.
For example;
are systems where the user can install their own coil and cotton.
Using an RBA coil requires more technical knowledge than using a ready-made coil.
Low-power MTL SMOK coil options can be used with Salt liquids.
However, not all SMOK coil systems are suitable for Salt liquid use, especially those with high nicotine concentrations.
Options such as LP1, RPM MTL, high-resistance Nord, and similar low-power coil options are in the class more commonly used with Salt liquid.
Low-resistance high-power coil systems such as RPM 3, D-Coil, TA, TFV16, and TFV18 should not be evaluated in the same usage class as high-nicotine Salt liquids.
You can check the Salt Liquid category for Salt product options.
Freebase e-liquids with appropriate nicotine concentration and VG/PG ratios can be used in SMOK coil systems.
The use of low-nicotine Freebase e-liquids is common, especially in low-resistance high-power DTL coil systems.
There are also Freebase e-liquid options prepared for MTL usage.
VG/PG ratio should not be determined solely by the "SMOK Coil" name.
For a correct choice, the following must be evaluated together;
The coil itself or incorrect coil installation can be among the reasons for leaks, but not every leak is coil-related.
Leaks can be caused by;
The best SMOK Coil is not the same coil for everyone.
First, you must determine which coil family your pod or tank supports.
