The FreeMax 4 is the latest in the Fireluke series of tanks; widely regarded as some of the best sub ohm tanks of all time. The Fireluke 4 produces some of the best flavor possible thanks to its use of Freemax’s CoilTech 5.0 coils. These coils use SS904L mesh and tea fibber cotton for crisp, pure flavor.
The Fireluke 4 is compatible with coils from the Fireluke 2 and Fireluke 3, as well as all coils from Freemax’s X Mesh Coil Series. In total, there are 17 coil options available in a variety of resistances and coil materials. This gives you more coil choices than almost any other tank on the market.
Included with the Fireluke 4 is a new 0.15Ω mesh coil and a 0.2Ω double mesh coil. You can also purchase triple and quadruple mesh coils separately. While the coils that come included with the Fireluke 4 are good, do yourself a favor and pick up a pack of the quadruple mesh coils. You won’t regret it!
The Fireluke 4 is built with a leak-resistant design but it’s still super easy to fill. Simply lift and slide the top cap back to reveal the fill port. This design means that you can throw this tank in your pocket or bag, but not have to worry about the top cap loosening and leaking. The Fireluke 4 will hold a respectable 5ml of ejuice which should be more than enough ejuice to get you through your vaping day.
For airflow, the Fireluke 4 has large adjustable airflow slots on the bottom of the tank. The airflow is smooth and direct, and it can be adjusted to achieve anywhere from an airy direct lung draw to a slightly restricted direct lung draw.
All around, the Fireluke 4 is an amazing sub ohm tank that delivers exceptional flavor thanks to its use of Freemax’s CoilTech coils. Plus, you can vape at up to 90W with some of these coils and chuck some massive clouds. If you’re looking for an excellent flavor and cloud tank, you can’t go wrong with the FreeMax Fireluke 4.

HorizonTech is frequently praised as one of the best manufacturers of subohm tanks; the Falcon Legend proves why. The Falcon Legend encompasses what a great tank should be with its professional design, great airflow, excellent flavor, and wide range of available coils. In total, there are ten coils that can be used with this tank.
The Falcon Legend uses new M series coils which use bamboo pulp cotton for the wicking material for better wicking and flavor. You get two coils in the package, a 0.15Ω M8 coil (pre-installed), and a 0.15Ω M6 coil. In addition to these coils, the Falcon Legend is compatible with all other Falcon M and F series coils.
The two mesh coils that come with the Falcon Legend are very similar to one another. They’re both 0.15Ω resistance, and they’re both meant to vaped at around 65-70W. However, you can easily push these coils beyond their rated wattage, up to around 80-85W, without an issue. Both coils deliver fantastic flavor that is head and shoulders above most other tanks.
The Falcon Legend features a threaded top cap that comes off with a quarter-turn. It has enough resistance that it’s not going to come off accidentally, but there’s knurling that makes removal easy when you want to take it off. Overall, we found the top cap to be very secure.
The airflow on the Falcon Legend enters the tank through three adjustable, medium-sized slot airflow holes. The airflow with both coils is the same; a slightly restricted direct lung draw with the airflow open, and a restricted direct lung draw with the airflow closed down.
If you like to have no restriction with your tanks then the Falcon Legend may disappoint you. For anyone who likes a slight restriction to their draw though, the way the airflow hits wide open is perfect.
This tank is a great one overall from all aspects, with a clean design, lots of coil options, a nice draw, and good flavor. But buyer beware, the Falcon Legend guzzles ejuice so be prepared to purchase bottles more frequently.

VAPORESSO is a vaping brand that is known for their excellent pod vapes, pod mods, and vape mods and kits. The iTank 2 is their latest subohm tank and although it comes included with a few of their mod/tank kits, the performance makes it worth purchasing as a standalone tank
The iTank 2 is a direct upgrade to the original iTank and improvements have definitely been made. One thing that has stayed the same is the huge 8ml capacity with the bubble glass installed, so you won’t have to fill up too frequently.
The top cap swivels back and opens upon pressing a button, revealing a self-closing silicone fill port. This button is very firm and takes direct and intentional pressure to open so accidentally opening it is unlikely, however you’ll still want to be careful.
The iTank 2 uses VAPORESSO’s GTi series of coils. These coils are made with VAPORESSO’s “COREX Heating Tech” and deliver excellent flavor, wicking capabilities, and coil lifespan. Included with the iTank 2 is a 0.2Ω coil and a 0.4Ω coil, however there are also 0.15Ω and 0.5Ω coils available to be purchased separately. These coils come in packs of 5 and they are readily available for purchase at many online vape stores for around $13.
Coils are plug-n-play and simply push or pull out of the base of the tank. You have to first unscrew the tank from the base to gain access to the coils but it’s all straightforward from there.
The performance of the iTank 2 firmly places it as one of the best tanks that we’ve used. The included coils deliver the best performance for this tank, but you can always try out the other coils for yourself and see if you like them; the options are there.

The Sakerz Master is yet another unique and capable sub-ohm tank by HorizonTech. It brings incredible clouds and flavor, as well as a clean and beautiful tank design. It has a 28mm base diameter, a 5ml max tank capacity, and it comes in 5 colors.
Like HorizonTech’s previous Falcon tanks, the Sakerz Master uses new coils that use wood pulp cotton as a wicking material and mesh as the heating element. These coils wick quickly, provide awesome flavor, and will last for 70ml+ of ejuice without showing any signs of giving out. These are some of the best coils around for flavor, clouds, and coil life.
Included with the Sakerz Master are two great coils: one 0.16ohm fine mesh coil and one 0.40ohm regular mesh coil. The fine mesh coil delivers a direct lung draw and superb flavor. The regular mesh coil isn’t quite as flavorful, but still holds its own against the majority of subohm tanks. This coil delivers a restricted direct lung draw that is really enjoyable to vape on.
The filling system on the Sakerz Master is quite easy to use. The top cap unscrews with a quarter turn to reveal a large fill port. The top cap is easy enough to remove but still secure enough that it won’t come off in your pocket.
The airflow on this tank is smooth, satisfying, and relatively quiet. This is a top airflow tank, but the airflow slots feed into two channels that funnel the airflow down to the bottom of the tank and under the coil. This gives you 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 mesh coils deliver excellent flavor. The Sakerz Master is a great sub-ohm tank and it sits comfortably on our list as one of the best sub-ohm tanks in 2023.

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.

HorizonTech has once again delivered an incredible tank for subohm vapers with the Aquila. The Aquila tank is a go-to subohm tank for the flavor chasers out there, delivering excellent flavor in a clean design.
The Aquila tank is available in 5 colors and uses mesh coils built with what HorizonTech calls their “Encircle” (E2) and “Quadruple” (P4) mesh structures, consisting of organic bamboo pulp cotton for the wicking material. These coils push and pull out of the bottom of the tank, making them very easy to replace.
The E2 coil, a dual mesh coil, is super flavorful and delivers great clouds all throughout the recommended wattage range of 60-70W. The P4 is not as flavorful as the E2 but still delivers an excellent vaping experience. The Aquila tank manages to get every last drop of flavor from your favorite ejuice, and it’s by far one of the most flavorful tanks yet.
This tank comes with a bubble glass pre-installed, which will hold up to 5ml of ejuice, and a spare straight glass in the package which can hold up to 3.5ml of ejuice. The drip tip is a standard 810 drip tip in black, no matter which color you purchase. It is quite comfortable but can be replaced with your own 810 drip tip.
The Aquila 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 Aquila is also great and enters the tank through three adjustable, medium-sized slot airflow holes. Whether you prefer a tight DTL draw or a more airy draw, the Aquila has got you covered.

Sporting a sleek looking form factor with a simple and clean design, the UFORCE-L tank is a beauty. Not only is it designed in a way that looks good, but it’s practical too. The UFORCE-L will hold 4ml of ejuice with the straight glass, or 5.5ml with the included bubble glass.
The UFORCE-L is a top airflow tank, so the possibility of leaking is greatly reduced. The three airflow slots can be adjusted using the airflow control ring, which rotates freely 360° without a stopper. This allows you to set the airflow however you like and get the draw just right.
The UFORCE-L comes with both a 0.20Ω coil and a 0.15Ω coil. Both of these coils are made with Voopoo’s “Dual In One tech”, which just means that they have a double mesh design inside.
No matter which coil you use, this sub ohm tank produces awesome flavor. The UFORCE-L is also compatible with many of Voopoo’s PnP coils, so there are plenty of coil options to try.
One thing that really impressed us about the UFORCE-L is the longevity of the included coils. You can run 20ml+ of ejuice through these coils before the flavor starts to drop off, and even then it’s a barely noticeable difference. If you use ejuices that aren’t too heavy on the sweetener, you can easily vape 30ml+ of ejuice with a single coil.
This tank features a convenient top-fill design where you simply remove the top cap with a quarter turn, stick the nozzle of your ejuice bottle into one of the two fill holes, and fill her up! The fill port location is lined with silicone and the fill holes self-close when you’re done filling. It’s a super secure design, so you’ll never get leaking from the top cap.
The flavor and cloud production of this tank are among the best you can get from a sub ohm tank and the coil choices give you plenty of options to try. All-in-all, the UFORCE-L is a great choice for any flavor-chasing vaper.

The Fireluke Solo uses Freemax’s latest FM COILTECH5.0 coils which are built with military-grade SS904L mesh and upgraded tea fiber cotton. These coils use mesh coils that fully surround the cotton and this results in more even heating, as well as longer coil life. Not only that, but this mesh structure also delivers great flavor and large clouds. For the best mid-high wattage sub ohm tank, the Fireluke Solo is the one.
Included with the Fireluke Solo is one 0.15Ω mesh coil and one 0.2Ω double mesh coil, but there is also a 0.15Ω triple-mesh coil that is available to be purchased separately. These mesh coils provide a tasty, flavorful and intense vape that definitely ranks among the best of the best sub ohm tanks.
The Fireluke Solo features an easy to use, slide-to-open top fill system. Simply slide back the top cap and fill your ejuice. As for airflow, the Fireluke Solo is a cloud beast. It has large airflow slots located at the bottom of the tank and these are fully adjustable to achieve the draw that you want. This tank has an ample 5ml ejuice capacity using the included bubble glass.

With the huge success of the Crown line to live up to, the Valyrian 3 is another great sub-ohm tank from Uwell. Aiming to reclaim its position as the best sub-ohm tank, the Valyrian 3 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 3 uses specifically designed mesh coils to achieve the same effect but with even better flavor and clouds.
Included with the Valyrian 3 are two mesh coils: one 0.32ohm SS316L 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. The Valyrian 3 is also compatible with Valyrian 2 coils. Although newly released, the Valyrian 3 is already becoming known as one of the best flavor tanks that you can get.
Filling is super convenient as the Valyrian 3 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 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 3 is quite large at 6ml and this means that you will get a good while of vaping out of this beast before having to refill. All things considered, the Valyrian 3 is definitely a sub-ohm tank that is worth checking out.

The Geekvape Zeus Max isn’t just a pretty sub-ohm tank. It has a 26mm base diameter, 4ml max capacity, and utilizes Geekvape’s brand-new M series 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 Max includes a 0.14Ω M coil and a 0.2Ω M coil. There are also 0.15Ω and 0.3Ω coils that are sold separately. 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 Max 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. Its stellar performance, flavorful coils, and its beautiful design are enough to earn the Geekvape Zeus a spot on our list.

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
- Convenient
- 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.
