Best Sub-Ohm Tanks To Buy In 2024: Bow Down To The Cloud Chasing Kings
Sub-Ohm tanks, as the name suggests, are tanks (usually with a DTL vape style) that utilize coils with a resistance of less than one Ohm. The lower a tank’s coil resistance is, the thicker and larger the vapor it produces, which means that you’ll get more flavor out of your e-liquid. So, if you’re looking to chuck flavorful, massive clouds, a sub-ohm vape tank might be what you’re looking for.
Our Comprehensive Sub-Ohm Tank Review Process
The sub-ohm tanks featured in this review have been chosen with coil resistance, battery voltage, and wattage in mind. While all of these factors play a role in determining the overall experience a vape tank has to offer, we gave coil resistance a bit more attention since it really defines sub-ohm vaping, immensely affecting a tank’s overall performance with just a slight change. Battery voltage and wattage, on the other hand, are responsible for a tank’s actual generated power and the amount of vapor and flavor it is capable of producing.

What is a Sub-Ohm Tank?
With the continuously evolving sub-ohm technology, sub-ohm tanks have seen drastic improvements over the years, to the point that the quality of vapor they produce is comparable with rebuildable tanks. This is achieved by utilizing thicker wires, thanks to the tank’s bigger surface area for providing a bit more room for the current to flow.
Sub-ohm tanks are suitable for those who prefer vaping DTL-style since they provide plenty of airflows. However, those who prefer vaping MTL-style will probably not enjoy sub-ohm tanks even with the airflow holes all closed down. Sub-ohm tanks come with pre-built coil heads with a resistance of 0.5 ohms or lower and typically require powerful vape mods that work at high wattages.
Advantages and Benefits of Sub-Ohm Tanks
Convenience
Sub-ohm tanks were invented to make sub-ohm vaping more accessible to more people – eliminating the need to dig deep into advanced electrical concepts to build coils.
A great thing about sub-ohm tanks is that they use pre-made and replaceable coils like regular vape tanks without compromising performance. In fact, their performance has been comparable to rebuildable tank atomizers.
Also, a sub-ohm tank’s coil works well with high VG (vegetable glycerin) e-liquids, essentially improving one’s DTL vaping experience with a smoother throat hit. The latest sub-ohm tanks also don’t get you stuck with just a single coil as they allow you to experiment with various coils so you could find just the right one for you.
The variety of options they offer, combined with their high-performance level, achieves intense flavor and huge, impressive clouds are made a lot easier. Sub-ohm tanks leave you with just three things to do: popping in a coil, filling it up with e-liquid, and, most importantly, enjoying your vaping experience.
Excellent and Intense Flavor
Sub-ohm tanks are known for their excellent vapor production. Because of the increased e-liquid vaporization happening in sub-ohm tanks compared to tanks with a tighter airflow, you can expect tons of flavor and even notice flavor notes that you didn’t know were there.
Sub-ohm tanks enhance the subtleties of an e-liquid’s flavor, the subtleties that aren’t noticeable when vaping on coils with higher resistance.
Increased Vapor Production for Huge Clouds
The enormous clouds of vapor that sub-ohm tanks are capable of producing attract a lot of vapers looking to take their vaping experience up a notch.
This increased vapor production is all thanks to the larger coils used in them as they heat up a bigger surface area of the wick faster, therefore producing huge clouds.
Also, the fact that sub-ohm tanks allow for better air circulation and that you’ll most likely be using high VG e-liquids with it only increases their potential for more vapor.
Warmer Vapor
For some people, a warmer vape is more enjoyable, and this is easily attainable with sub-ohm tanks. This is mainly because of how quickly it takes a sub-ohm tank’s coil to heat up, as well as the fact that sub-ohm tanks require more power or wattage.
A sub-ohm tank’s increased airflow also proves to be useful with regards to the vapor’s temperature as it kind of balances the warmness and coolness out, resulting in the vapor that is just the right amount of warm.
This sweet spot gives off a pleasant sensation that’s a little similar to what cigarette smokers get when lighting a cigarette.
Smoother yet Stronger Hit
Sub-ohm vaping is arguably more satisfying because of the gentle, soft, and strong hit it provides. With sub-ohm vaping, using e-liquids with lower nicotine concentration is recommended since sub-ohm tanks perform well in delivering more nicotine into your lungs.
With that said, using high-nicotine e-liquids for satisfaction is unnecessary as they tend to feel very harsh to the lungs because of the warmer vapor a sub-ohm tank produces.
With the continuously evolving sub-ohm technology, sub-ohm tanks have seen drastic improvements over the years, to the point that the quality of vapor they produce is comparable with rebuildable tanks. This is achieved by utilizing thicker wires, thanks to the tank’s bigger surface area for providing a bit more room for the current to flow.
Sub-ohm tanks are suitable for those who prefer vaping DTL-style since they provide plenty of airflows. However, those who prefer vaping MTL-style will probably not enjoy sub-ohm tanks even with the airflow holes all closed down. Sub-ohm tanks come with pre-built coil heads with a resistance of 0.5 ohms or lower and typically require powerful vape mods that work at high wattages.
Choosing the right sub-ohm tank that suits your needs can be quite a task with the number of sub-ohm tanks on the market today, but some major things to consider when choosing one include the amount of e-liquid it can hold, its filling method, and its wicking materials.
A sub-ohm tank with a large e-liquid capacity will not require you to refill your tank constantly, and one with an easy filling method, like one with a top-filling system, will make refilling a breeze. Lastly, the wicking materials that sub-ohm tanks utilize vary from model to model, so if you’re after the best flavor, you might want to look into tanks with mesh coils or other more advanced ones.
Disadvantages of Sub-Ohm Tanks
The main downside to sub-ohm tanks is how they’re not suitable for MTL vapers. MTL vaping has that tight, cigarette-style draw, which many vapers, especially those trying to quit smoking, prefer. Another is that sub-ohm tanks aren’t exactly discreet and can be a real attention drawer with the amount of vapor they produce.
Also, they are quite a battery drainer since they require more power, consuming a lot more e-liquid as a result. Lastly, sub-ohm tanks tend to have a weaker throat hit; while no one wants a harsh throat hit, some vapers find a stronger throat hit more enjoyable.
Because a high HV e-liquid with a low nicotine concentration is to be used with sub-ohm tanks, you’ll instead get a gentle, smooth hit rather than a strong one.
Sub-Ohm Tanks FAQ
How does a Sub-Ohm Tank Work?
Sub-ohm tanks work the same way as regular vape tanks. However, sub-ohm tanks are geared towards high-powered setups.
A sub-ohm tank’s coil head attaches to the tank’s base, and the cotton wick absorbs the e-liquid, which becomes vapor when it comes in contact with the heated-up coil.
When taking a hit, the e-liquid is pulled by the suction towards the coil. The latest sub-ohm tanks almost always feature a top-fill system, and sports open airflow holes for that DTL draw while also keeping the coil from getting overly hot.
With sub-ohm tanks, increasing the amount of vapor the coil produces is as easy as increasing the unit’s battery power; more power means results in a hotter coil, and a hotter coil produces more vapor. Keep in mind that an excessively hot coil can burn your wick and cause the vapor to become uncomfortable and taste burnt.
Is Sub-Ohm Vaping Safe?
Nothing is truly absolutely safe. When engaging in sub-ohm vaping, it is important to have a good understanding of Ohm’s law and to know your batteries’ capability since sub-ohm vaping taxes a unit’s batteries pretty heavily, heightening the risk of battery damage – the main risk for vaping safety.
With that said, you should always gain prior knowledge about your specific device and adhere to the manufacturer’s recommended wattage range for use with your sub-ohm tank’s coil to avoid electrical fault.
Are Mesh Coils Better than Traditional Coils?
Since mesh coils do a great job of heating the wire’s surface area, as opposed to traditional coils’ way of heating (from the middle outward), they are generally better than traditional coils.
Mesh coils make for bigger clouds, less hot spots, and more efficient wicking while also giving you exceptional flavor.
Additionally, mesh coils tend to last longer than traditional ones, and they work quietly without any spit back.
Can You Put any Sub-Ohm Tank on any Mod?
Pretty much any 510-threaded sub-ohm tank will fit onto any 510-threaded mod.
However, a pair isn’t always guaranteed to work. For instance, if a tank has a coil resistance that’s lower than the mod can fire, it just won’t work.
And generally, you shouldn’t put a sub-ohm tank and a hybrid top mech mod together because the battery will make direct contact with the atomizer.
Conclusion
While we love all the sub-ohm tanks mentioned above, the FreeMax FireLuke 2 is without a question our favorite.
Aside from how well the coil resistance, voltage output, and wattage output of each coil in the TX Mesh Coil series work together, the way each component of this sub-ohm tank is designed is commendable.
From the feeding design and patented wicking formulation to the coil’s unique diamond pattern, every little part and the systems it utilizes just seems to be really well thought of – ticking every box in the list of what a sub-ohm vaper is looking for: a smooth draw, rich flavor and vapor, no leaking and spit back, easy refilling and airflow adjusting, and the list goes on.
The overall vaping experience this flawlessly-designed tank offers is just incredible.
