Best Sub-Ohm Tanks – The Top Vape Tanks For Every Vaper
Sub-ohm tanks came to prominence after vapers began tinkering with their first-generation clearomizers and atomizers. Sub-ohm tanks are made of several disassembled parts and offer more advanced features like airflow control and inhalation style (MTL or DL). Sub-ohm tanks also let users install different coil types to obtain more flavor or cloud size.

The Uwell Valyrian II is a new sub-ohm tank that features a stainless steel build and an extended e-juice capacity. The Valyrian II is an update to the original tank and it is compatible with those coil types so vapers can use them with this tank. The new tank has an 8ml e-juice capacity thanks to its wider, 32mm diameter that is specially designed to work with larger, dual-cell mods. The tank also comes with two distinct coil heads which are both mesh-style coils but have either single or dual coil designs.
Available in 4 great colors (black, gold, stainless steel, rainbow)
Protected by a warranty
Easy to understand user manual
Great for vapers who like low-wattage vaping
Small e-liquid capacity without the 4.2 mL spare glass extender
The Cleito 120 is the upgraded tank that has recently been added to the Aspire’s Flagship Cleito product line. There were two specific things kept in mind during the making of this tank. First, it was designed for massive cloud making. Second, its design is now compatible for mesh coils.
A purchase of this tank comes with lots of extra goodies in the box. Vapers will receive a pre-installed 0.5 ohm coil designed to work for 60-80 watts. They also get a 0.15ohm mesh coil that works with watts between 60 and 75. Lastly, they will get a spare glass tank extender that expands the 3 mL tank to 4.2 mL, spare o-rings, a user manual, and a warranty information card.
The .15 mesh sub ohm coil that comes with the Aspire Cleito is what makes this tank so great. Mesh coils are preferable for many reasons. First, they work better with lower wattages and are better at evenly distributing heat. They also are more conducive to massive cloud brewing, but do not sacrifice intense taste for volume. Once a vaper starts using a mesh coil, they will likely never want to go back.
The Falcon King uses the same winning blueprint of the original Falcon tank. The Falcon tank featured a unique flax paper coils, made of flax fiber and wood pulp for a unique flavor. At 25.4 mm in diameter goes 4 ml juice capacity, with up to 6 ml with a bubble glass upgrade.
New to the Falcon King is a series of organic coils, such as the 0.16 ohm M1+ Mesh coil made with bamboo fiber and organic cotton (rated at 75W), and the 0.38ohm M-Dual coil that uses the same materials but features a dual mesh setup (rated at 80W). The organic mesh grants high temperatures almost instantaneously, and pure flavors without dry hits.
The Falcon King is cross-compatible with all previous Falcon coil system parts. The Falcon King tank includes both the single 0.16-ohm mesh organic coil and the dual 0.38 mesh organic coil. A spare Pyrex 4 ml glass tube and a user manual are also included.
There is one unique feature of the Uwell Valyrian sub ohm vape tank. Namely, there are three separate and interchangeable center pins.
Standard center pin
Rounded center pin
Spiral center pin
Swapping center pins is easy. They all vape much the same. The spiral center pin seems to make the vaping extra smooth. You can experiment with each pin to see what you think.
Uwell Valyrian Coils
There is only one coil option for the Valyrian, but it is a beauty! A fantastic big coil that makes amazingly consistent vapor. The juice ports are massive. In fact, keep an eye on the minimum juice fill line on your coil. These coils are on the expensive side, but they last a long time and make a lot of vapor. The coils are rated at 0.15 ohms and can be vaped at 85 watts to 120 watts. You are going to get plenty of vapor at 85 to 95 watts.
The Uwell Nunchaku sub-ohm tank features a unique plug-and-pull coil removal system. The tank can hold 5ml of e-juice, in a quartz-reinforced glass tank. The diameter of the tank measures one inch. Underneath the atomizer features a 510 pin for secure connection with similarly-threaded mods. There are also copper, silicone and stainless steel elements within the tank’s construction.
The coil system on the Nunchaku does not use threaded coils. It uses a threadless, plug-and-pull style, which makes replacing them easier. The Nunchaku kit features two of these coils. One coil is 0.4ohms and can vape between 45-55W.
The other coil can fire as low as 0.25ohms, and rates for anywhere between 40-50W. The interior of the tank features a unique condensation holder. This separate compartment keeps e-juice free from exposure to excess moisture. The Delrin drip tip is removable and wide-bore for more massive cloud production.
There are two adjustable airflow slots underneath the glass section. The tank has a top-fill design for easy refilling. The kit features spare parts, like a quartz glass tank, as well as the two Claptonized coils, which are made with Kanthal wire.
The tank must be emptied before replacing the coil heads
No RBA deck available
Fireluke Mesh Tank uses a kanthal mesh coil to give a more dramatic flavor.
This 24 mm sub-ohm tank comes in steel, resin, and carbon fiber finish; the Fireluke Mesh Tank has both a great look and performance.
Thanks to its well-thought design and construction, you can quickly refill juice from the generously large top fill ports without using a dropper.
The mesh coil is rated 0.15 ohms and works best between 40W to 90W to give weeks of longevity.
Other features include a matching 810 wide drip tip, and a standard 510 connector to fit virtually any mod. There are two adjustable airflow slots to provide more control over vape clouds.
At 46.5 mm wide, the Fireluke Mesh Tank holds up to 3 ml of ejuice.
Each Fireluke Mesh Tank includes two mesh 0.15-ohm Kanthal coils, 1 Pyrex glass tube, one bag of Spare O-Rings and a user manual.
The SMOK TFV16 represents the pinnacle of vaping engineering as it is the largest and widest tank from the SMOK label so far. The tank boasts a 32mm diameter, at its widest point, while its base diameter measures 28mm (1.1”). The e-juice capacity is also unprecedented (for a sub-ohm tank) as the tank can hold 9ml with a heat-resistant, Pyrex glass bubble piece stretching the bounds of what is possible. The tank also comes with several coils options that allow users to push the tank to its brink. Users will find mesh coils in different styles like a single (0.17-ohms), dual (0.12-ohms), or triple mesh coil (0.15-ohms) or with a conical design (0.2-ohms).
The stock drip tip is narrow and limits vapor production
Uwell Crown 4 sub-ohm vape tank inherited a top-notch construction quality with a classic Crown tank series features, such as top-filling ports, triple adjustable airflow ports, and a twist-open top cap.
Another unique feature to the Uwell Crown 4 is the innovative self-cleaning chamber.
This patented self-cleaning technology sucks up all the excess juice at the bottom of the generous 6 ml tank, preventing any leaks and cuts down the number of cleaning sessions on a tank.
With the Uwell Crown 4 come two sub-ohm coils, a 0.4-ohm coil rated for 60W to 70W, and a 0.2-ohm coil rated for 70W to 80W. Both coils are constructed with SS904L standard round wire.
The modular design of the Crown 4, allows to take it apart quickly to swap out new coils or to clean a tank.
The Uwell Crown 4 sub-ohm vape tank includes a 6 ml bubble glass, a 5 ml straight tube glass, an 810-drip tip cover, two sub-ohm coils (0.4 and 0.6 ohms) and a user manual
Now, if you are looking for maximum vapor and want to push your high powered mods to the hairy edges, then you want the TFV12 Cloud King. The new T12-V12 can be vaped at up to 350 watts. That is not a typo! If you have a quad mod capable of 350 watts, then you will be able to go to the extremes of vaping.
The TFV12 is 25 mm at the base has 27 mm in diameter tank glass. The extra diameter is needed for this massive tank because the coils are just enormous. This tank is incredibly well built with fantastic airflow. One thing to keep in mind is that you might want to reduce your typical nicotine level when vaping the Smok TFV12 sub ohm tank. You will be inhaling a lot more vapor than usual, so it would be appropriate to reduce the nicotine content.
Smok TFV12 Sub Ohm Vape Coils
Of all of the serious cloud chasing tanks, TFV12 coils are the most affordable and most available. Coil prices vary depending on which option you select. Because of its popularity, most retailers carry them. TFV12 coil options include:

Do You Really Need a Sub-Ohm Tank?
Ask yourself this question.
Are you unsure, whether the best sub-ohm tank will be the best choice for you or not? Let’s weigh their pros against their cons and see whether sub-ohm vaping is the right choice for you.
BENEFITS OF SUB OHM VAPING
There are two types of vaping styles. Standard vaping with atomizers above 1.0-ohms, and sub-ohm vaping with atomizers below 1.0-ohms. When you are standard vaping you draw the vapor into your mouth and then inhale. When you are sub-ohm vaping, you draw the vapor directly into the lungs. This is MTL, mouth to lung, vs. DL, direct lung.
When you are vaping a standard atomizer coil above 1.0-ohms, you will use a vape juice that is 50% PG or more. When you are sub-ohm vaping, you will use an e-liquid that is more than 50% VG. Remember as well that with sub ohm vaping you will not need an e-liquid with any more than 6 mg of nicotine. If you vape direct to the lung, you’ll simply love the sub-ohm vaping experience. In fact, once you sub-ohm, you won’t go back. On the flip, if you prefer mouth to the lung, above ohm vaping gear is the way to go. Although not written in stone, it’s the easiest way to gauge whether a top sub-ohm vape tank is ideal for you.
Sub-Ohm Tank Vapor Production
When it comes to vapor production, standard vaping doesn’t even come close to sub-ohming. The vapor production is considerably higher. In fact, that is the biggest charm behind the best sub-ohm vape tanks. It has become a competitive sport. People compete against each other to see who blows the biggest, thickest plumes of vapor. Cloud chasing is the pursuit of the biggest clouds of vapor possible.
The fact that you are inhaling so much more vapor is why VG e-liquids for sub-ohm vape tanks contain less nicotine than PG e-liquids for standard vaping.
We have a couple of quick tips for choosing an e-liquid blend for you sub-ohm vaping tank. An e-liquid or vape juice that is 70% to 80% VG is the sweet spot for vapor production and flavor. Max VG e-juices will make even more vapor, but will not be as flavorful.
Sub-Ohm Tank Flavor
This is where things get a little crazy. You would think that the flavor intensifies because you’re inhaling more vapor. But, with the increased airflow and speed at which vapor is inhaled directly to the lungs, it leaves little time for your taste buds to extract the taste. You get to savor the flavor on the exhale. The flavor performance was one of the leading qualifying criteria that we used to determine the best sub-ohm vape tanks. A lot of factors determine the flavor performance of a sub ohm tank. The quality and construction of the coils being chief among them. Organic cotton coils deliver the best flavor. The combination of airflow and juice ports that keep the wick saturated is a secret sauce for vapor flavor.
Finally, little things like the distance of the coils from the drip tip can impact the flavor. Of course, the quality of the vape juice you are using is critical. Cheap, poorly made vape juice tends to be overly saccharine and flavor challenged shall we say! You sub ohm vape tank deserves a good juice. Find proven, transparent e-liquid brands and your vaping experience will be much better for it.
More Excitement, More Innovation, More Fun
When compared to vaping standard cartomizers or tanks, sub-ohming opens a new world of innovation. In fact, most of the innovation has been dedicated to developing the best sub ohm vape tanks.
The innovations have taken diverse paths. Tanks like the TFV12 are all about maximum vapor. No holds barred insane vapor! Other tanks strike a balance between vapor production, flavor, and ease of use. Others yet are geared toward affordability. Every type of innovation has its place and will appeal to a cross-section of vapers.
There are vape tank innovations in drip tip design, airflow design, and chimney design. Minor changes can drastically alter the vaping experience. It is a lot of fun to experience.
We have also seen incredible innovation and improvement in sub-ohm coils over the years. The best tanks have the best coils. Manufacturers also strive to make coil swapping easier for vaper.
Is Temperature Control Vaping Sub-Ohm?
Yes, it is. Temp control vaping is achieved with sub-ohm coils. But, instead of Kanthal coils temp control coils must be made of compatible wire. Examples of temp control wire are nickel, stainless steel, and titanium. Some of the top-rated sub-ohm vape tanks on our list do give you the option of using temp control coils. We did not consider this a factor in the ranking structure. Our focus was to evaluate these devices as sub-ohm tanks. If you are interested in temp control, look for products that give you the coil options that accommodate TC vaping.
From temperature ranges to coil materials to top filling designs to RBA heads, there is just so much to experiment. You’ll never get enough of it.
Disadvantages of Sub-Ohm Vaping
Big Dent to Battery Life
Sub-ohm tanks need a lot of power and wattage to offer optimal performance. Small e-cig and mod batteries do not have the power required to bring the vapor. You will be best served by a device that operates on 18650 batteries or an internal battery with a capacity of at least 1,500 mAh. Mods with dual 18650 batteries should provide ample power except for the extreme cloud chasers.
What this means for you is that you’ll be charging your battery more frequently. Since the resistance of the coil is low, more current flows through it. The battery gets some beating. It’s akin to water flowing through a pipe: the wider the pipe is, the more water will flow.
We recommend using an external battery charger for your 18650 batteries. You will also want to have spare, fully-charged batteries on hand and ready to go.
Heavier on Your Pocket
Sub-ohm vaping can be more expensive than standard vaping. Sub-ohm vaping tanks not only uses more battery power but also consumes more e-juice. Those big clouds come at the cost of excessive e-juice. And if you use a high-quality, expensive e-liquid, it can impact your budget.
That said, you do not want to skimp on your vape juice. The best sub-ohm vape tanks will give you full enjoyment of your juice. Cheap juice made in the back room of a vape shop might save you a buck, but quality vape juice always vapes better.
Stealth Vaping Is out of Question
This is a no-brainer. If you want to vape around people but don’t want others to notice, you have to choose above-ohm vaping. Sub ohm vape clouds will be noticed!
NO MOUTH TO LUNG VAPING
Sub-ohm tanks usually have a loose airflow so you can take the draw easily. It’s pretty much like drinking soda through a straw. Therefore, you won’t be able to do mouth to lung hits. As a result, the vapor won’t stay in your mouth for long enough for you to savor the taste.
IT CAN BE RISKY
Sub-ohm vaping has become much safer than it used to be a few years ago. This is thanks to powerful, precision regulated vape mods. By regulated, we don’t mean legally; we are talking about control boards, or chips, that control power output. Not only are mods better but the best sub-ohm vape tanks today are amazing. Finally, better batteries have also contributed to a safer vaping experience.
However, since you virtually stretch the batteries to their maximum capacity, it can be comparatively riskier. But again, the stats show that probability of a vape battery explosion is one in a million.
The best-rated sub ohm tanks have made vaping safer by making it easier. Follow the recommended wattage ranges to avoid stressing batteries and frying atomizer coils.
SUB-OHM VS. ABOVE-OHM VAPING
Apparently, there are more downsides than advantages of sub-ohming. However, the vapor production and the excitement simply outweigh all the cons. It all boils down to your personal preferences. If you sub-ohm for a while, chances are you’ll get hooked on it and never go back.
What Makes a Good Sub-Ohm Tank?
Let’s see what the qualities of a good sub-ohm tank are. The Bigger, the Better? Maybe. But then, it all depends on your vaping style. Having a 5ml or even bigger sub-ohm tank is great as you don’t have to refill very often. This can be a plus depending on how often you vape. Ideally speaking, you should go for a big tank size. On the flip, it can increase the overall size of the mod.
Also, are you one of those souls who always want to try new things? You might want to try new flavors as well, and bigger might not be better. Trying to switch to a different flavor can be a problem if you already have a full 5ml tank.
Look, the bottom line is this. Big sub-ohm vape tanks can accommodate larger coils. Bigger coils can bring more vapor. Can a small sub-ohm vape tank and small coils deliver as much vapor as a cloud chasing tank like the TFV12? No. But, a little tank can bring perfectly respectable sub ohm vapor production. For practical, everyday vaping, a small sub-ohm tank will do just fine.
The final verdict is that larger diameter sub-ohm vape tanks with huge coils produce more vapor than smaller tanks. Many vapers like to have a small tank for day to day needs and have a big sub ohm tank at home for maximum clouds in their leisure time.
TYPE OF COIL
This didn’t use to be a big factor until lately. However, with so many different options available, you might be missing out if you continuously use the same coils. For example, a Kanthal coil is ideal for use with ordinary variable wattage vaping. As a general rule, the lower the atomizer resistance, the higher wattage you can vape. Low resistance and high wattage equal more vapor.
You can completely change the vaping experience just by swapping coils. On the other hand, you can also use nickel, stainless steel, and titanium on a mod with temperature control.
Your mod will pretty much dictate what type of coil you ought to choose. Different e-liquids will have a slightly different taste with different types of coils. It is something that experience will teach you. Try out different types of coils and the settle down with the one that floats your boat. Or, don’t settle down at all! It’s up to you.
Another factor that can impact your vaping experience is the style of the coil. For instance, some modern tanks come with Clapton-style coils, which somewhat look like guitar strings. You should also consider the number of coils (some have up to 12 coils) and their alignment (vertical vs. horizontal). Vertical coils usually outperform the horizontal ones and are more common.
Most sub-ohm tanks allow customization regarding air flow control. For direct lung inhalers, a wider airflow is better and vice versa. A tank with wider airflow options is a better choice.
There is a whole line of RTAs that come with a rebuildable atomizer (RBA). However, there are a few sub-ohm tanks that include an RBA in addition to the built-in options. This is a great feature for rebuilders who want to try sub-ohming.
TOP-FILLING DESIGN VS. BOTTOM-FILL DESIGN
The top-filling design is extremely easy to fill and is becoming increasingly popular. Rather than having to take apart the sub-ohm tank, simply uncap the top and refill.
Another important factor is the wicking material. The most common material is Japanese organic cotton. There are a few sub-ohm vape tanks that offer a ceramic coil. The latter offers the advantage of additional heat resistance. This means you can fire the mod with an empty tank and there won’t be any damage to the wick.
On the flip, a cotton wick will burn pretty quickly. This little feature not only improves the flavor but also prolongs the lifespan of your coils. But this doesn’t mean that we can rule out cotton. In fact, comparing apples to apples, cotton will offer a better taste.
Some other features that you may consider including liquid flow control and anti-spit back system. Liquid flow control allows you to regulate the speed at which your juice reaches the coil. As a result, it gives you a lot more control over the overall performance.
Anti-spit back is an innovative design mouthpiece that stops the hot juice from going into your mouth. Moreover, certain sub-ohm tanks will have a cooling system for those who don’t like the hot vapor.
Tips for Using Sub Ohm Vape Tanks
Always read the user manual of your sub-ohm vape tank. There are some variations of how sub-ohm tanks function. Here are a few tips common to all tanks:
Use an e-liquid with more than 50% VG
70% VG e-liquids offer a great combination of vapor and flavor
Max VG e-liquids have less flavor but more vapor
Always prime your sub-ohm vape coils
“Priming” is placing a few drops of e-juice directly on the cotton visible through the juice ports on the coil
After priming, assembling, and filling your tank – wait at least five minutes before vaping
Waiting at least five minutes will allow the wick to become fully saturated with e-liquid
When refilling a sub-ohm vape tank, it is a good idea to close off the airflow to prevent leaking.
Finally, it is a good idea to break in new sub-ohm coils slowly. For instance, you don’t want the first hit on a new coil to be at maximum wattage. Start out at the low end of the wattage range and gradually increase.
Final Word on Sub-Ohm Vaping
Sub-ohm tanks are pretty much like supercars. They are high performance, but they are not for everyone. And if you think you’re cut out for sub-ohming, make sure to consider all the things we have discussed above. It’s best to do some research and then use it along with your personal preferences to choose a tank. Feel free to choose any of the best sub-ohm vape tanks we’ve mentioned above. All of the tanks on our list have been put through their paces and proved their metal in real-world conditions. We test these tanks that way that you will use and enjoy them. Go with a proven performer and ensure that your vaping will be all that it can be!

My way of understanding the significance of vaping came not only through the disruption of smoking but its effects on society as a whole. Now I bring people to vaping and bring vaping to people. I love using new gear, writing in-depth reviews and generally nerding out about vaping to like-minded people.
