No matter if you’re a beginner or an advanced expert, sub ohm tanks are a sure staple in any vapers collection. Because of their easy-to-use nature, sub ohm tanks are usually the first go-to vape tank for most beginner vapers, but more advanced vapers love them too for their great flavor and cloud production.
But with so many different and varying sub ohm tanks out there it can be hard to know if you’re getting a great vape tank or just throwing your money and ejuice down the drain. So to save you the time and money, we’ve created a list of the best sub ohm tanks of 2021. We’ve chosen these sub ohm tanks based on their flavor, cloud production, airflow and tank capacity.
Best Sub Ohm Tanks of 2021: The Best Vape Tanks Right Now
The nexMesh Pro has a large 6ml tank and a secure fill port to prevent leaking. It comes with an extremely flavorful clapton mesh coil, as well as a unique mesh & round wire coil. Also avaialble are conical coils that concentrate the vapor as it travels upwards for increased clouds and massive flavor. The nexMesh Pro is our pick for the best sub ohm tank of 2021.
WHY TRUST US
All of our reviews are based on market research, expert input, or practical experience with most products we include. This way, we offer genuine, accurate guides to help you find the best picks.
OFRF are best known for their excellent mesh coils, like the ones included with the Wotofo Profile Unity RTA. Their mesh is loved for it’s quick ramp up times, large vapor production and amazing flavor. Now, Wotofo has taken that same mesh and incorporated it into a sub-ohm tank for those who may not use rebuildables. The nexMesh Pro Tank has a large 6ml max capacity and features a silicone guard on the fill port to prevent leaking.
Two very unique coils come included with the nexMesh Pro. The first is a clapton mesh coil that uses kanthal A1 as the core wire and ni80 as the outer, wrapping wire. This coil delivers RDA-like performance that is hard to imagine from a sub-ohm tank. The second coil is a dual coil but with a single mesh core and a double wire regular coil core. This coil allows you to experience the clouds from a mesh coil, with the flavor accuracy of a regular round wire coil.
In addition to the two included coils, the other available coils for the nexMesh Pro Tank further set it apart from the competition. These coils have a “conical” structure where the mesh is shaped like an upside down funnel. In other words, the top of the coil is a little more narrow than the bottom. This makes the coil heat up more quickly and also concentrates the vapor as it travels upwards for increased vapor and flavor production.
Along with the conical shape, these coils use both an outer and inner layer of cotton to give them the best wicking capabilities of any sub-ohm tank; you can take multiple long draws in a row without ever having a dry hit.
If building your own coils is your thing, you can do that with the nexMesh Pro, too. An RBA coil is sold separately so you can use your own builds with the nexMesh Pro.
The nexMesh Pro is a leak free tank that stays bone dry, all while providing incredible flavor and vapor that you wouldn’t think possible from a sub-ohm tank. But do yourself a favor and pick up a pack of the H13 and/or H11 conical coils when you buy the tank. You’ll thank us later.

The Falcon 2 is the follow up to one of the best sub ohm tanks ever. It has an impressive design that looks great and it’s available in five attractive colors. Each color comes with its own matching resin drip tip.
The defining feature of this tank, and the reason why it produces such good flavor, is its 0.14ohm sector mesh coils (best used at 70-75W). These coils are plug’n’play and not threaded like the coils for the original Falcon or Falcon King so they aren’t backwards compatible. These coils are wider at the bottom and more narrow towards the top of the coil. This condenses the vapor to provide a more dense and flavorful draw.
The Falcon 2 has a push to open top cap that is convenient to open but still very secure — it’s not going to open unless you try to open it. The Falcon 2 has three large airflow slots that can be easily adjusted to suit your draw preference.
The flavor from the Falcon 2 is as good, if not better, than the Falcon King. It has a 5.2ml ejuice capacity with the bubble glass installed and this is more than large enough to last heavy vapers through a day of heavy vaping. There aren’t many tanks that can compare to the full, crisp flavor that the Falcon 2 delivers.

HorizonTech are known for producing some innovative tanks and coils, and the Falcon King is the latest addition to their impressive lineup. Just by taking one look at the color choices for the Falcon King you’ll be impressed by the unique hues and matching resin drip tips.
The thing that sets the Falcon King apart from its competitors are its five available mesh coils produced with unique wicking materials:
- M1+ coil — 0.16ohm, 75W (bamboo fiber)
- M-Dual coil — 0.38ohm, 80W (bamboo fiber)
- M1 coil — 0.15ohm, 70-80W (wood pulp+cotton)
- M2 coil — 0.16ohm, 70-80W (wood pulp+cotton)
- M-Triple coil — 0.15ohm, 80-85W (wood pulp+cotton)
These coils are all amazing but the best one will vary according to your vaping style and preference. To get you started, the Falcon King includes an M1+ and M-Dual coil.
The Falcon King features a swivel top fill system that is very convenient. Simply press the button on the top cap and it will swing open, allowing you to fill your desired ejuice. The airflow on the Falcon King is also great and enters the tank through three adjustable, wide-slot airflow holes. Whether you prefer a tight DTL draw or a more airy draw, the Falcon King has got you covered.
The flavor that you get off of this vape tank is insane. Plus, the tank capacity of the Falcon King is 6ml with the included bubble tank section which should be more than large enough to last you a full day of vaping. Definitely worth picking one up. Hell, it’s so good it might be a good idea to grab two!

The FreeMax Maxus Pro (or M Pro 2) is the follow up to Freemax’s Mesh Pro, one of the best sub ohm tanks of all time. The Maxus Pro produces some of the best flavor possible thanks to its use of Freemax’s CoilTech 4.0 coils. These coils use SS904L mesh and tea fibber cotton for crisp, pure flavor.
The Maxus Pro is compatible with coils from the original Mesh Pro tank. This means that not only do you get coil options that are designed specifically for the Maxus Pro, but you also have the option of using other coils as well.
Included with the Maxus Pro is one 0.15Ω single mesh coil and one 0.2Ω double mesh coil but you can also purchase triple and quadruple mesh coils separately. While the coils that come included with the Maxus Pro are good, do yourself a favor and pick up a pack of the quadruple mesh coils. You won’t regret it!
The Maxus Pro is built with a leak-resistant design but it’s still super easy to fill. On the metal edition you just have to lift the top cap before sliding it back to reveal the fill port. On the resin edition there are 3 steel balls that add friction and greatly reduce the chance of the top cap opening accidentally. These designs mean that you can throw this tank in your pocket or bag without having to worry about the top cap loosening and leaking. The Maxus Pro will hold a respectable 5ml of ejuice and will last you long through your vaping day.
For airflow the Maxus Pro has large adjustable airflow slots on the bottom of the tank. The can airflow be adjusted to achieve anywhere from an airy direct lung draw to a slightly restricted direct lung draw.
All around, the Maxus Pro is an amazing sub ohm tank that delivers exceptional flavor thanks to its use of CoilTech 4.0 coils. Plus, you can vape at up to 110W with the triple or quadruple mesh coil and chuck some massive clouds. If you’re looking for an excellent flavor and cloud tank, you can’t go wrong with the FreeMax Maxus Pro.

The Augvape Intake is a unique and capable sub-ohm tank. It brings incredible clouds and flavor, as well as a dominant and beautiful tank design. The highlight of the Intake Subohm tank is its use of all-new Clapton mesh coils.
Clapton wire is made of a smaller, thinner wire wrapped around a larger core wire. Because of the increased surface area of the wire, more ejuice is vaporised and this results in more flavor. Clapton wire is nothing new, but it’s a new concept for pre-built coils.
Included with the Intake are three great coils: one 0.15ohm regular mesh coil and two 0.20ohm Clapton mesh coils. The Clapton mesh coils deliver warm vapor and superb flavor. The single mesh coil isn’t quite as good as the Clapton mesh but it holds its own.
The filling system on the Intake is quite easy to use. The top cap unscrews with a quarter turn to reveal two large fill ports. The top cap is easy enough to remove but still very secure.
The airflow on the Intake is smooth and satisfying. This is a top airflow tank, but the airflow slots feed into two tubes that funnel the airflow to the bottom of the deck. This gives the flavor of a bottom airflow tank, but with the leak resistance of a top airflow tank.
It’s unique, it’s leak resistant, and the Clapton mesh coils deliver excellent flavor. The Intake is a great sub-ohm tank and it sits comfortably on our list as one of the best sub-ohm tanks of 2021.

The Fireluke 3 is the successor to one of the best sub ohm tanks of all time, the Fireluke 2. The FireLuke 3 mesh coils heat up more evenly than regular coils and they last longer too. Not only that, but mesh also means a more flavorful vape and larger clouds. For the best mid-high wattage sub ohm tank, the FireLuke 3 is the one.
Included with the FireLuke 3 is one 0.15 ohm mesh coil and one 0.20ohm double mesh coil but it’s also backwards compatible with the original Fireluke and Fireluke 2 coils. These mesh coils provide a tasty, flavorful and intense vape that definitely ranks among the best of the best sub ohm tanks.
The FireLuke 3 features an easy to use, slide-to-open top fill system. Simply slide back the top cap and fill your ejuice. There are three steel balls for added friction to prevent the top cap from opening accidentally. As for airflow, the FireLuke 3 is a cloud beast. It has large airflow slots located at the bottom of the tank and these are fully adjustable to the draw that you want.

But she’s not only a pretty face. The Wirice Launcher is the only sub ohm tank that lets you change the coils from the top! Just remove the drip tip, remove the old coil, and drop in your new coil. The wicking ports close when you remove the coil so you don’t even have to empty the tank!
The Wirice Launcher comes with both a 0.21Ω coil and a 0.15Ω mesh coil. No matter which coil you choose, this sub ohm tank produces awesome flavor and the 0.15Ω coil will allow you to chuck some pretty respectable clouds too.
The Wirice Launcher features a convenient top-fill design where you simply unscrew the top cap, stick the nozzle of your ejuice bottle into one of the two fill holes, and fill her up! This fill system is great because it’s super secure so you’ll never get leaking from the top cap. The Wirice Launcher will hold 4ml of ejuice with the straight glass or 5ml with the included bubble glass.

Few coil options
This 25.5mm tank is compatible with Vaporesso’s entire line of GT coils. These are the same coils used in the Vaporesso Sky Solo Plus and the NRG PE tank that comes with the Swag II kit. There are 8 different GT coils in various resistances and material types. The sheer amount of coil options ensures that you’ll find a coil that you like.
The NRG-S is super easy to fill. The top cap slides and swivels back and takes a decent amount of pressure to pop open. The fill port is wide enough to accomodate bottle nozzles or droppers and is lined with silicone for leak resistance.
There are two adjustable airflow slots on the NRG-S which are located at the bottom of the tank. The airflow control ring is on a stopper so it can be fully closed if needed.
Eliquid capacity for this tank is great. It can hold 8ml of ejuice with the bubble glass and 5ml with the straight glass. This is one of the largest capacities on a sub-ohm tank — it doesn’t get much larger than this.
The dense clouds, great flavor, and awesome coil compatibility make the NRG-S one of the best sub ohm tanks you can get. You don’t take our word for it; pick one up and see for yourself.

Multi-core coils use a lot of ejuice
With the huge success of the Crown line to live up to, the Valyrian 2 is the latest sub-ohm tank from Uwell. Aiming to reclaim its position as the best sub-ohm tank, the Valyrian 2 has been redesigned and outfitted with a few unique features to set it apart and provide a more flavorful vaping experience.
One of these features is the self-cleaning system that was first seen on the Crown IV. This system allows any condensation that accumulates at the base of the tank to be reabsorbed by the coil. This prevents any leaking caused by condensation build-up and helps to keep the airflow control ring bone dry.
While the original Valyrian used interchangeable pins to enhance the airflow and flavor of the tank, the Valyrian 2 uses specifically designed mesh coils to achieve the same effect but with even better flavor and clouds.
Included with the Valyrian 2 are two mesh coils: one 0.32ohm single mesh coil and one 0.14ohm dual mesh coil. The large surface area of the mesh and their even heating results in incredible flavor and the clouds are no slouch either. Although newly released, the Valyrian 2 is already becoming known as the best flavor tank you can get.
Filling is super convenient as the Valyrian 2 uses a hinged top-fill system. By pressing a small button on the side of the tank, the fill cap pops up to reveal the fill holes. As for airflow, there are three large adjustable airflow slots located at the base of the tank that provide a hard-hitting, direct lung draw.
The tank on the Uwell Valyrian 2 is quite large at 6ml and this means that you can get a good while of vaping out of this beast before having to refill. All things considered, the Valyrian 2 is definitely a sub-ohm tank that is worth checking out.
Available Coils UN2 Single Mesh — 0.32ohm (90-100W)
UN2 Dual Mesh — 0.14ohm (80-90W)
UN2 Triple Mesh — 0.16ohm (90-100W)
Quadruple Coil — 0.15ohm (100-120W)

The Geekvape Zeus isn’t just a pretty sub-ohm tank. It’s got a 26mm base diameter, 5ml max capacity and utilizes brand-new Mesh Z coils for optimal flavor and clouds. It’s also a top airflow tank so there’s no need to worry about ejuice leaking out of the airflow slots; it’s basically leakproof.
The Zeus includes a 0.4ohm Z1 mesh coil and a 0.2ohm Z2 mesh coil. Each coil will function best at different wattages which we’ve included in a table below. Regardless of which coil you use, the flavor is up there — especially for a top airflow tank.
The stellar performance of the Zeus is due to its top-to-bottom airflow design. Airflow is immediately funneled from the top airflow holes and down through two large channels that lead straight to the coil. This stellar performance, its flavorful coils and its beautiful design are enough to earn the Geekvape Zeus a spot on our list of the best sub ohm tanks of 2021.
Available Coils 0.40ohm (60-70W)
Tank Capacity 5ml Airflow Dual Wide-Slot, Adjustable Top Airflow
Good build quality

What is a Sub Ohm Tank?
A sub ohm tank is actually quite simple to understand. Simply put, a sub ohm tank is a tank that is meant to use premade, replaceable atomizers (coil +cotton) at less than 1.0 ohm. Sub ohm tanks are very user-friendly, and easily allow you to change the atomizers with factory-made ones that you can purchase from any reputable vape shop.
In addition to their ease of use, sub ohm tanks are also very easy to take apart and clean, have large tanks that will hold tons of ejuice, and will provide great flavor and huge clouds. All of these benefits mean that a good sub ohm tank is: low hassle, great to take on the go, and most importantly — a great performer.
Reasons to Use a Sub Ohm Tank
There are many reasons to use a sub ohm tank:
- Easy to use
- Great flavor
- Large vapor production
- Lots of airflow
Sub ohm tanks are much easier to use than any other type of vape tank. While rebuildable tanks like RDAs and RTAs require you to build your own coils, sub ohm tanks use coils that come ready to be used. All you have to do is screw or push the coil into the tank, fill your tank up with ejuice and wait for 5-10 minutes and you’re ready to vape!
The flavor produced by modern sub ohm tanks is amazing. Thanks to new advances in both tank and coil design, the best sub ohm tanks allow you to taste every note and nuance of your ejuices.
Last but not least, sub ohm tanks provide a lot of airflow and this results in huge clouds! If you’re a cloud chaser then a sub ohm tank is the way to go. Most tanks have at least two, if not three, wide airflow slots. This allows you to adjust the draw to exactly how you like.
Drawbacks to Using a Sub Ohm Tank
- Not meant for MTL vapers
- They use a lot of ejuice
- Not as cost effective as rebuildable tanks
The main drawback of a sub ohm tank is that they aren’t for vapers looking for a tight, MTL draw. The draw from most sub ohm tanks is going to be very airy. If you like the draw of a cigarette, you’re better off going with a pod vape.
Another drawback of using a sub ohm tank is that they use a lot of ejuice. Because sub ohm coils need a lot of wattage, they also vaporize a lot more ejuice with each draw. This results in more ejuice being used more quickly than it would be if you used a lower powered device. For this reason, finding a good cheap ejuice is recommended.
Lastly, sub ohm tanks aren’t as cost effective as rebuildable tanks. The coil for a sub ohm tank has to be changed every two weeks and buying coils can quickly add up. If you’re trying to be as cost efficient as possible, you can look into a tank that you can build your own coils for like an RDA, RTA or RDTA.
How Does a Sub Ohm Tank Work?
Sub ohm tanks use premade, replaceable coils to absorb and vaporize ejuice. These premade coils have a wicking material inside of them (usually cotton). Most sub ohm tanks have a port on the top of the tank that allows you to fill it with ejuice.
When your tank is filled with ejuice, the cotton absorbs ejuice through holes on the outside of the coil. The cotton will also pull in ejuice when you inhale on the mouthpiece as this creates suction; this is how the coil gets saturated with ejuice. When you press the fire button on your mod, the coil heats up and vaporizes the ejuice.
How to Use a Sub Ohm Tank
Sub ohm tanks are the most straightforward type of vape tank to use. Unlike rebuildable tanks, you don’t need any tools. All you need is the tank, a coil, and some ejuice.
It’s a good idea to prime your coil before inserting it into the tank. This is where you drop some ejuice into the holes on the outside of the coil to get it pre-saturated. For more information, check out our guide on how to prime a coil properly.
In order to insert the coil, you’ll need to disassemble the tank. Most tanks will unscrew from the airflow control ring at the bottom of the tank. With the tank apart, take your sub ohm coil and insert it into the tank. Depending on the tank, it might need to be screwed in or it might just push into the tank.
With the coil inserted, reassemble your tank. Now you can fill it up with ejuice. Most sub ohm tanks have the fill port located just underneath the top cap. Some top caps slide back, others unscrew, and some have a button release. Fill your tank up with ejuice and close the top cap. Wait for 5-10 minutes for the coil to fully saturate. Once the waiting period is over, you’re ready to vape.
Depending on the resistance of the coil, the best wattage to vape at will differ. Most coils have the recommended wattage printed on the outside of the coil. For the best experience, stay within this recommended wattage range.
Can I Use any Coil With Any Sub Ohm Tank?
No. While some sub ohm tanks are compatible with multiple types of coils, like the Hellvape Hellbeast sub ohm tank, it still can’t use just any coil. Most sub ohm tanks only work with one specific type of coil. For instance, if you purchase the Horizontech Falcon 2 sub ohm tank then you’ll need to use the Falcon 2 sector mesh coils.
What Is the Best Eliquid To Use In a Sub Ohm Tank?
Generally, higher VG ejuices are best in sub ohm tanks. This is because they’ll provide a smoother draw. Look for an ejuice with at least 60VG to use with your sub ohm tank.
What is the Best Wattage to Vape At With a Sub Ohm Tank?
Depending on the resistance of the coil, the best wattage to vape at will differ for each coil. Most coils have the recommended wattage printed on the outside of the coil. For the best experience, stay within this recommended wattage range.
What Nicotine Strength Ejuice Should I Use In my Sub Ohm Tank?
Using too high of a nicotine strength will result in harsh draws that will hurt your throat. It’s recommended that you use a 0mg, 3mg, 6mg or 9mg nicotine strength ejuice with sub ohm tanks.
How Long Does a Sub Ohm Coil Last?
All coils are different and so the amount of time they’ll last varies, but you can generally expect to get 1-2 weeks out of a sub ohm coil.
Coil life also depends on the wattage that you vape at and the type of ejuice that you use. Ejuices with a lot of sweetener will severely gunk up your coils and cut their usage times short. Similarly, exceeding the recommended wattage of your coil will also cut the usage time considerably.
What’s Better: a Sub Ohm Tank or an RDA?
While sub ohm tanks are meant to be used with factory-made, prebuilt atomizers and come with a tank that allows you to fill it with ejuice and vape away, RDAs are quite a bit different. With an RDA, you have to build your own coils with your own vape wire and cotton, and there isn’t really a “tank” like sub ohm tanks. Instead, you’ll have to drip your juice into the RDA every so often in order to continue vaping without any dry hits. If you want to learn more about RDAs you can read our article here.
