A List Of The Top 5 Sub-ohm Tanks

Selections of sub-ohm tanks form an ever-changing menu of accessories available to serious vapers with serious machines. Next week something new and better might be released but, for now, here is a list of best sub-ohm tanks to help you get started. They are all reasonably priced and made by respected Chinese manufacturers.

1. Sigelei Moonshot

Sigelei Moonshot

Sigelei’s new sub-ohm tank is the newest product in this write-up; a Chinese-American RTA with a crater-sized Delrin-protected mouthpiece letting out steam and distinguishing this tank from those of competitors. There is a dual-post rebuild deck, Cyclops-style airflow adjustment opening, and a Pyrex glass tank supported by stainless steel. Fill up and vape at up to 200 watts.

2. Kanger Toptank

Kanger Toptanks

Anything upgraded is supposed to be better than the original and that’s true here. The Toptank improves on features of the Subtank by Kanger, particularly with respect to refilling. Add e juice at the top now instead of the bottom as you do when using the Subtank (also a great tank). Kanger supplies stainless steel OCC replacement coils and also an RBA, sold separately. The regular Toptank holds up to 4 ml of e juice. Kanger also makes a 3.2-ml Nano with an even smaller tank option. The Toptank is ready to roll with TC mods. No other lineup of tanks is as colorful as the Toptank which match assorted Kager mods like the SUBVOD and KBOX.

3. UD Zephyrus V2

UD Zephyrus V2

UD’s most recent offering in the sub-ohm category is a reliable addition to your collection. UD’s Zephyrus, version 2, provides top-filling capacity and a 6-ml tank which is bigger than most so you aren’t refilling constantly during a long vaping session at high temperatures. Customize airflow through 4 valves, two at the top and two at the bottom, setting precise draw quality and vapor temperature. An anti-condensation hole releases the pressure which sometimes leads to flooding. Numerous potential coil builds have been created for the Zephyrus 2 using organic cotton.

4. Eleaf MELO 2 TC Tank

MELO 2 Atomizer

Eleaf had their TC vape mods in mind when they designed the MELO 2 but it’s perfectly suited to several temperature control devices such as the eVic VTC and any mod featuring mid-range wattage output. That means you can replace the tank atop your iStick 40W with the MELO 2 or add it to a DNA40 by Hana Modz. Tank capacity of 4.5 ml is significant, if not huge, but the design is simple and stately. Select temperature control coils made from Nickel 200 or Titanium to vape with your TC mod or choose pre-built Kanthal coils when you are planning to operate a mod in Variable Watt mode up to approximately 80 watts. Refill from the side: now that’s a unique feature.


SMOK TFV4 Black and Silver

It’s not that this SMOK tank ranks lower than the others: in fact, many times their TFV4 would be a chart-topper, but let’s not be predictable here. SMOK makes a fine product, but I have a feeling there is something else up their sleeve ready for imminent release; a product to top even their mighty TFV4 sub-ohm tank for high-watt devices and even temperature control vaping at high temperatures. They can’t ride on the popularity of this excellent tank forever; not even with their stylish colored O-rings and sturdy build. The SMOK TFV4 has the agility to handle several types of vaping setups. Heat e juice at up to 200W with Kanthal and push it through coils as low as 0.1 ohms using temperature-sensitive materials. There are so many coil choices you should prepare with an atomizer pop-quiz before going shopping. Customers can even buy a sextuple coil. The optional rebuild deck and compatible 510 threading connection give users the versatility they need to vape however they want with any model of e cig such as a SMOK XCube, Innokin Cool Fire IV, Sigelei 90W, or the Tesla 200.

Sub-Ohm Tanks: A Cloud-Chasing Revolution

Cloud chasers are people who vape with the goal of creating a lot of vapor. They are not as concerned with flavor or cost efficiency as they are with how thick their plumes are, and they even run competitions to see whose vapor is thickest, travels farthest, is whitest (purest), etc. If you had to try and pinpoint the most extreme, even fanatical vapers around you would have to say they were the ones.

Sub-Ohm Vaping

They can achieve these clouds owing to a revolution in the development of high-watt vape mods and tanks to go with them. Early on, these devices were variable wattage/variable voltage units in tube or box shape and they would be filled with the best e juice brands like King’s Crown and Five Pawns.

At the highest settings these devices could create amazing vapor, especially with low-ohm coils installed in their specialized tanks made by big name brands. Top brands were developing better coils in a variety of configurations such as the Bottom Vertical Coil (BVC) which could cope with thick e juice and would become famous for their cloud-making capacity.

It would also become clear that certain e liquids were better for cloud-chasing than others and they would come to support the efficacy of high-end tanks. These were (and still are) e liquids made from at least 50% vegetable glycerin, but often more: up to 100%.

Sub-Ohm Changes

Now there are more brands than ever of both tanks and mods. They include VW/VV devices and VW/TC devices (temperature control).

There are still tubes and box mods with the majority favoring a box-like shape of some kind. These systems have become sophisticated enough to run at up to 200W and offer resistance below 1 ohm; even under 0.8 ohms.

Would you believe it’s possible to run a vape mod setup at as little as 0.05 ohms in the correct setting (TC) using special coils (Ni200 or Titanium)? Safety features are much improved too, so it’s usually not dangerous to operate a high-watt, brand-name device by the likes of Kanger, SMOK, HCigar, or Hana Modz knowing they each contain tried and tested control boards.

Sub-Ohm Tanks

You don’t have to be a TC vaper to experience the joys of sub-ohm vaping, but your atomizer must support the output you wish to create with your device. At 40W or more, you can reach sub-ohm resistance if your tank is suitable. What makes it a suitable tank? There are a few features.

• adjustable airflow
• sub-ohm coils
• glass tube
• stainless steel caps

Caps are the top and bottom parts of a tank which attach to the glass and provide the base for a drip tip (top), atomizer, and airflow control valve (bottom). Innokin released a polycarbonate (PC) iSub made from the most modern PC available but they soon upgraded to an iSub G and iSub Apex as it became clear how much customers prefer glass.

The reason is that glass does not release fumes at high temperatures and it does not break down. Tell consumers that top-rated PC is also stable but they aren’t so sure: glass is a known quantity. Stainless steel is also preferable because it is non-corrosive, durable, and stable at high temperatures. It won’t start to break down at 100W and well-made items are smoothly threaded.

Adjustable airflow allows the vaper to control vapor temperature to a point but mostly determines how tight or airy the draw is. As you delve into sub-ohm vaping, these customization features are more important. Experienced consumers expect maximum control over every part of their experience. Some sub-ohm tanks also feature juice control and drip tip airflow adjustment.

Coils for sub-ohm vaping must be at least dual coil but sometimes feature quad or even octuplet coil (the Arctic V8 by Horizon). Multiple coils create more vapor than single coils and are also able to cope with thick e juices.

Optional Extras

As a bonus, your sub-ohm tank could be top-fill oriented. A few mods can be filled at the top or the bottom and there is also a side-fill tank made by Eleaf. Top-fill orientation allows you to refill e juice during a vaping session without removing the atomizer tank from your mod.

It’s a way to cut down on mess and hassle when you are probably filling juice frequently — high temperatures tend to burn e juice rapidly. With the top-fill method, there is potentially less mess because a tank turned upside down would leak liquid through the drip tip. If you close the airflow valve of a top-fill tank, it won’t leak during the refill process.

Temperature-sensitive coils are optional. Ni200 and Ti coils (Nickel 200 and Titanium) are suitable for TC vaping and, in fact, necessary for using the TC function on a vape box. They hold their temperature better than Kanthal at lower wattage and they also burn down relatively slowly making them especially efficient. Vapers experience fewer dry hits with TC coil too.

A third bonus is the RBA head: a deck which some sub-ohm tanks contain so you can build your own coils. There are loads of pre-built coil heads around for assorted tanks in lots of resistance options but the RBA allows you to be fussy about material and build style.

Models of Sub-Ohm Tanks

The top names in tanks are Aspire and SMOK, with Horizon close behind them. Kanger is another excellent tank builder, famous for their low-resistance Aerotank and Protank but now also for the Subtank Plus, Nano, and Mini.

Aspire’s fame spread with their Nautilus tank but this is a low-resistance accessory: their Atlantis was the breakthrough they needed in order to reach the sub-ohm vaping audience. They have also released a Triton tank and the Cleito since then.

SMOK’s TCT and TFV4 are top sellers: the latter is especially flexible. Horizon’s Phantom tank is among the most innovative with its juice recycling system and numerous windows through a metal cover into the tube. Eleaf’s Melo 2 and the Uwell Crown are both excellent. Threading on mods and tanks is usually flexible so you can take your pick of tank.

Vaping Tanks Guide

Electronic cigarette clearomizers, glassomizers, and tanks are often classified within the same category. Alternatively, tanks and rebuildable or dripping atomizers are frequently listed under the same heading.

Tanks share something in common with both: they are rebuildable but will be filled with around 2.5 ml or more of liquid at a time. They are frequently associated with adjustable mods whereas RDAs and RBAs are often listed alongside fully mechanical mods. The latest tanks bridge the gap between tube tanks and RDAs.

Top Names in Vaping Tanks

The best names in tank manufacturing are both Chinese: Aspire and KangerTech. JoyeTech has just entered the market too with their Delta and SMOK makes several noteworthy products. Tanks from these companies are generally reliable, but there is variety in the product style and purpose.

Vaping at Low vs. Sub-Ohms

If you are vaping with an APV, your coils are generally built for low but not sub-ohms: maybe up to 2 ohms and as low as 1 ohm. For vaping at lower than 1 ohm, your tank coils must either be pre-built, ready for your VW mod, or rebuildable.

This is where a tank becomes a hybrid: when there are either two atomizer heads for separate functions or a single atomizer head can be rebuilt. The Kanger SubTank comes with two heads so that the user can either default to the pre-wrapped format or build his own coils to a chosen resistance.

Features of Tanks

A traditional tank is combined with a cartomizer which runs through the middle of the tube and contains wick, cotton, or mesh. Japanese Organic Cotton is considered the purest material available for this purpose. New atomizer heads with the abbreviation OCC stand for Organic Cotton Coil.

Tanks come in several parts. One is the drip tip, usually a removable piece, but sometimes built into the top cap. There is a bottom cap, glass (usually Pyrex) tube, sometimes an adjustable airflow valve, and potentially an airflow valve near the mouthpiece. Within the bottom cap is an atomizer head. All of these pieces are replaceable.

Many companies supply a stainless steel sleeve with the tank or as an optional accessory. Usually, it is decorated with holes so that one can see liquid levels, enjoy the appearance of an attractive tank design, but also protect the glass from ordinary knocks which occur during normal usage.

Features One by One

Popular vaping tanks like the Nautilus and Aerotank are beloved by vapers for several reasons. One is their materials: stainless steel and Pyrex. Another is that they are economical owing to the rebuildable nature of their design. Third is the presence of adjustable airflow.


This is the part where a vaper changes the resistance of his draw, not resistance between atomizer and watts/volts. Sometimes vapers like an easy draw and perhaps they like the draw to be more restrictive.

That is not the same as cooling vapor before it gets to one’s mouth. An airflow inlet at the top, near a mouthpiece (as seen on the Aspire Atlantis) affects the temperature of vapor before inhalation, a bit like a cooling device on an herbal vaporizer but without water or a double-helix cooling coil.


There is a lot of concern in the vaping world and the regulatory arena about toxins in e liquids and vapor. This is a valid concern emanating from the fact that temperatures high enough to vaporize liquid can also release fumes from certain materials.

As mods become more powerful, they are also capable of reaching much higher temperatures. Plastic or rubber components could, potentially, release toxins into vapor which spoil the flavor and maybe even make it poisonous to a degree well below the toxicity of smoking, but still measurable.

Pyrex isn’t just tough glass; it is a neutral component which offers nothing toxic to release. The same is true of stainless steel, a hygienic and durable material that won’t start melting until it reaches temperatures no vaper wants to play with.

Popular Vape Tanks

The Vivi Nova is an amazing, even beautiful tank. There are numerous colors you can buy and huge-capacity tanks. Prices are also excellent. Some say this is the most popular tank, but I would argue the Aspire Nautilus is even more popular and tends to run out of stock in a hurry. It possesses all the best components: airflow adjustment, Pyrex tube, and stainless steel caps.

An Aspire Atlantis is better than the Nautilus for sub-ohm vapers buying into the high-watt mod department. Consumers of this class of device prefer a low-ohm set-up because they run their mods at 50W and higher. Anything up to 80W is safe with the Atlantis.

A Subtank by Kanger is also good value for money, while Joye has released a version known as the Delta, now onto Version 2.0. Good tanks generally sell for between $20 and $40, reaching the higher numbers with more features and extras.
