Uwell Coil is the general name for the replaceable heating elements used in Uwell brand electronic cigarettes, pods, Pod Mods, and atomizer systems. The Uwell product range includes coil options with different resistances and power ratings, ranging from low-power MTL usage to DTL tanks above 100W.
In the Uwell ecosystem, the coil system varies significantly depending on the device family. While Caliburn G/G2 Series devices feature a coil system that can be replaced separately by the user, in current Caliburn GPP / G3 / G4 / G5 platforms, the coil is integrated into the cartridge, and the entire cartridge is replaced when its lifespan ends.
Additionally, the Uwell product family includes completely different coil platforms such as Crown PA Coil, Crown M Coil, Crown Nano Coil, and Valyrian V-Coil. Therefore, when purchasing a coil, one should check not only the brand or ohm value but also the exact model of the device, pod, or tank being used.
The shortest answer to the question “What is a Uwell Coil?” is that it is the consumable part that heats the e-liquid within the tank or appropriate pod system.
A pre-built coil generally contains;
When the device is activated, the coil heats up, and the e-liquid carried by the cotton turns into an aerosol.
For different brand coil options, you can check the Electronic Cigarette Coil category.
Caliburn G Coil is the Uwell pod coil system where the coil can be removed from the cartridge and replaced separately.
The basic coil options for the Caliburn G/G2 platform are;
as follows.
The Caliburn G/G2 coil platform has been used in many Uwell devices.
Compatible models include;
and other various products.
Caliburn G/G2 Coil and Caliburn G3/G4/G5 cartridge systems are not the same. While the coil can be replaced separately in the G/G2 generation, the coil is integrated into the cartridge in the new GPP platform.
The Caliburn G 0.8Ω coil is one of Uwell's low-power coil options featuring a UN2 mesh structure.
For the Caliburn G2 device, Uwell positions the 0.8Ω coil for a more open RDL usage and the 1.2Ω option for a tighter MTL usage.
The Caliburn G 1.0Ω coil is one of the high-resistance MTL options of the Caliburn G platform.
It is also offered as a compatible option in many G Series devices such as Caliburn G2, GK2, GZ2, Tenet, and Caliburn X.
The Caliburn G2 1.2Ω UN2 Mesh Coil is a coil option aimed at tighter and lower-power MTL usage.
It is supported in a significant portion of G2, GK2, GZ2, Tenet, and various G Series devices.
Currently, no separately replaceable coil is used for the Caliburn G3.
With the Caliburn G3 generation, Uwell transitioned to a pod system where the coil is integrated directly into the cartridge.
G3 cartridges feature different integrated coil resistances such as 0.6Ω, 0.9Ω, and 1.2Ω.
When the coil reaches the end of its life, the metal coil is not removed separately; the entire cartridge is replaced.
GPP stands for Uwell's current G Pod Platform cartridge system.
In GPP cartridges, the coil is integrated into the cartridge.
Current GPP options include;
different resistance and power options.
The GPP cartridge platform combines the Caliburn G3, G4, and G5 generations into a shared cartridge ecosystem.
Current GPP systems feature different filling options such as Side Fill and Top Fill.
Uwell aims for the cartridges in the GPP platform to provide mutual compatibility with Caliburn GPP Series devices.
GPP Alpha Cartridge is the new generation integrated coil cartridge platform introduced by Uwell in 2026.
GPP Alpha maintains existing GPP compatibility while continuing the structure where the coil and cartridge are replaced together.
Therefore, users who purchase GPP Alpha do not need to buy separate metal coils.
If you are looking for a “spare coil” for the Caliburn G5, in most cases, the product you need is a GPP/GPP Alpha cartridge, not a coil.
In the Caliburn G5/GPP platform, the basic integrated coil options are at the 0.4Ω, 0.6Ω, 0.9Ω, and 1.2Ω levels.
The current power pairings for the G5 KOKO are;
as follows.
No.
The metal coil is removed from the pod by the user and replaced separately.
The coil is integrated into the cartridge. The entire cartridge is renewed when the coil wears out.
These two systems cannot be used interchangeably.
Uwell PA Coil is the replaceable coil platform developed for the Crown D Pod Mod.
25–35W
DTL
15–18W
MTL / RDL
Within the same PA coil family, usage characteristics and wattage levels can change significantly.
Crown M Coil is the coil system specific to the Crown M Pod Mod.
In the Crown M platform;
options are available.
Crown M Twin Coil is a Uwell coil design that provides dual-output characteristics within the same coil body.
0.4Ω and 0.8Ω operation options are used at different power levels.
Crown M 0.6Ω is a standard RDL coil option separate from the Twin-Coil.
Crown Nano Coil is the coil platform developed for Uwell's current Crown Nano MTL Tank system.
10–14W
Tighter MTL
16–20W
MTL
Crown Nano is one of Uwell's current tank systems in the Crown family focused on MTL usage.
Valyrian IV Advanced V-Coil is the current DTL coil system developed for Uwell's high-power Valyrian IV Tank.
90–100W
High-power DTL
50–60W
DTL
Yes. In addition to the new Advanced V-Coil options, Uwell provides compatibility with the previous Valyrian III and Valyrian II coil families in the Valyrian IV Tank.
This creates a wide range of coil options in the Valyrian tank family.
The main options for the Valyrian III coil platform;
80–85W
SS316L
80–90W
FeCrAl
Certain Valyrian II coil options can also be used in Valyrian III and current Valyrian IV platforms.
These coils are in the high-power DTL usage class.
There is no single wattage value for the Valyrian coil family.
For example;
there are very different power values such as these.
Crown IV Coil is one of the older but still frequently sought-after sub-ohm coil platforms developed for the Uwell Crown IV Tank.
55–65W
60–70W
Crown IV coils are not the same as the current Crown Nano or Crown M coil platform.
No. “Crown Coil” is not a single coil platform.
Saying “Uwell Crown Coil” is not enough to choose the correct spare part. The full name of the Crown model must be checked.
There is a quite wide resistance range in Uwell coil and integrated cartridge systems.
The ohm value alone does not determine which device the coil will be used with or at what wattage it will operate.
No.
For example, the 0.8Ω resistance value in the Uwell product range can be found in;
physically completely different product platforms.
No.
Even if the electrical resistance of the coil is the same, the heating surface, coil design, tank airflow, and device power system may differ.
For example, while a PA 0.8Ω Coil operates at the 15–18W level, the power management of another 0.8Ω Uwell system may differ.
Therefore, the wattage range specified by the manufacturer for the coil or cartridge should be taken as the basis.
There is no single ideal wattage value for a Uwell coil.
In the brand's current product family;
there are very different power levels.
The maximum wattage of the device is not the coil wattage. The power range specified by the manufacturer for the coil or cartridge should be used.
Since the tank or pod airflow is also important in this classification, one should not decide based solely on the coil ohm value.
Mesh Coil is a coil technology that uses a wide-surface, net-like heating structure instead of a classic round wire.
Most of Uwell's current products feature different mesh coil technologies.
For example;
different mesh systems are found.
Mesh coil does not only mean low-resistance, high-wattage use; there are also 1.2Ω MTL mesh coil options.
Pro-FOCS is the trade name for Uwell's own atomization and flavor optimization technology used in many of their coil, pod, and tank systems.
New generation versions such as Pro-FOCS 4.0 are also used in current Uwell devices.
This technology is not a coil compatibility standard. Just because both products have Pro-FOCS does not mean their coils are compatible with each other.
The following sequence can be used when choosing the correct Uwell coil:
No.
The answer to the question “Which coil for Caliburn?” changes depending on the Caliburn generation.
0.8Ω, 1.0Ω, or 1.2Ω separate replaceable G Series Coil.
Uses GPP cartridge; the coil is integrated within the cartridge.
This distinction is important to prevent buying the wrong coil or cartridge.
Caliburn G5 uses the GPP cartridge platform.
For this device, a GPP or GPP Alpha cartridge with the appropriate resistance should be chosen instead of a separate metal coil.
There are different options in the GPP platform, such as 0.4Ω, 0.6Ω, 0.9Ω, and 1.2Ω.
The Crown series name alone is not enough to determine the correct coil.
In the Crown family;
there are completely different platforms such as these.
The coil changes depending on the generation of the Valyrian tank.
While the current Valyrian IV uses new Advanced V-Coil options, it also offers wide compatibility with previous Valyrian III and Valyrian II coils.
Therefore, the Valyrian tank family has a wider backward coil compatibility compared to many other Uwell platforms.
When a new Uwell coil is installed, the cotton inside the coil must be sufficiently saturated with e-liquid before the first use.
Firing at high power without giving the cotton time to absorb the e-liquid after filling the tank or pod can cause a dry hit or a permanent burnt taste.
Since the waiting and first-use method can vary according to the coil/tank design, the relevant Uwell user manual should be taken as the basis.
A new coil should not be fired dry. Before use, make sure the coil cotton is fully saturated with e-liquid.
Not all Uwell coils are threaded.
In many of Uwell's modern tank and pod systems, the coil may be push-fit, meaning it sits in place by being pushed.
Therefore, the phrase “definitely tighten the coil” found in older texts is not correct for all Uwell products.
The coil;
and the device's own installation method should be applied.
Priming is the process of completely saturating the cotton inside a new coil with e-liquid before the first use.
Preparing the new coil appropriately helps to;
There is no single definitive minute value that applies to all Uwell coil systems.
The saturation time can vary depending on coil size, cotton amount, and e-liquid viscosity.
Therefore, rather than a fixed “5-minute” or “15-minute” rule, the usage instructions for the relevant tank or device should be taken as the basis.
It is not correct to give a definitive number of days for the lifespan of a Uwell coil.
Coil lifespan can be affected by;
When the coil or integrated coil cartridge reaches the end of its useful life;
symptoms such as these may be observed.
In integrated coil cartridges such as GPP and G3/G4/G5, the metal coil cannot be replaced separately.
In case of a burnt taste or significant performance loss, the entire cartridge is renewed.
Therefore, “Caliburn coil lifespan” and “Caliburn cartridge lifespan” can refer to the usage period of the same consumable product in new generation devices.
Dry Hit is a condition of a dry and burnt taste caused by heating the coil without sufficient e-liquid in the coil cotton.
A low liquid level, not waiting long enough for a new coil, or very frequent consecutive puffs can increase the risk of a dry hit.
Pre-built Uwell coils are consumable parts designed to be replaced with new ones when they reach the end of their useful life.
When the cotton inside the metal body is burnt or heavy residue forms, it should not be expected that a pre-built coil will return to its completely original performance.
In integrated coil cartridges, the coil is not removed; the cartridge is replaced entirely.
Salt nicotine can be used in low-power MTL Uwell coil and cartridge systems.
However, not all Uwell coil systems are in the same usage class as high nicotine concentration salt nicotine e-liquids.
GPP 0.9/1.2Ω, Caliburn G high-resistance coils, and options like Crown Nano.
Valyrian and high-power Crown tank coils should not be evaluated in the same usage class as high nicotine salt nicotine e-liquids.
For salt nicotine options, you can check the Salt Nicotine category.
Freebase e-liquids with appropriate nicotine concentration and VG/PG ratio can be used in different Uwell coil systems.
Low-nicotine freebase liquids are in the common usage class for low-resistance Valyrian, Crown, and DTL coil systems.
Low-power MTL freebase options can also be used in suitable Caliburn and Crown Nano systems.
VG/PG selection should not be made based only on the name “Uwell Coil”.
In the selection;
should be evaluated together.
For liquid options, you can check the Electronic Cigarette Liquid category.
Incorrect installation of the coil or damage to the gasket section can be one of the reasons for leakage, but not every leak is directly coil-related.
Leakage can be caused by;
different situations like these can cause it.
The best Uwell Coil is not the same product for everyone.
The first criterion is compatibility with the device or tank you are using.
Uwell Coil prices; can vary according to the coil family, resistance value, mesh technology used, whether the product is a separate coil or an integrated cartridge, and the number of pieces in the package.
A fixed rule like “Uwell coils come in packs of 4” mentioned in old category texts should not be used for all current products.
When comparing prices;
should be evaluated together.
In Caliburn coil prices, the device generation is the first point that needs to be checked.
Separate coils can be purchased for the Caliburn G/G2 platform.
