Sub Ohm Tank Types

Tanks are a type of atomizer that are a good place for new vapers to start and also the easiest and most convenient to use.

There are 2 styles of tanks.

  1. MTL (Mouth to Lung)
  2. which are higher resistance and lower wattage coil with a similar draw to smoking and;

  3. Sub Ohm Tanks:
  4. which are DTL (Direct to Lung) tanks which are higher wattages with lower resistance coils with more airflow and you inhale directly into your lungs.

    This list will give you all the best options for both styles of vaping.

    There are a few terms and styles you should be familiar with when picking out a tank so let’s go over them all.

Coil Types

Sub Ohm Coils are generally rated by their resistance and wattage range. The main thing to look at is the wattage range. In general, higher wattages means it drains batteries quicker but it produces good clouds and flavor. There are also different wire types inside the coil heads.

  • Kanthal

    : is the most common and is used in power mode.

  • Nickel coils

    (ni or ni200 labeled)

  • Titanium

    (ti labeled) which are to be used in temp control only.

  • Stainless Steel

    Coils (SS or SS316 labeled) which can be used in both power and temp control modes.

Refill Types

There are 3 refill types on sub ohm tanks.

  • Top Fill

  • Side Fill

  • Bottom Fill

And it’s in reference to where you fill from. There is top fill, which usually means unscrewing a top cap and filling, although some sub ohm tanks feature a swivel design where you don’t need to unscrew to show the fill port. Then there is side fill, which will have a hidden fill port accessed by pulling up on the tank to expose it. And lastly, the older and not seen too often anymore, the bottom fill, which requires unscrewing the bottom base to fill directly into the tank. Top and side fill are the best options.


The coil heads usually all use organic cotton for it’s wicking material. Some sub ohm tanks use ceramic as wicking or have ceramic surrounding the cotton. Some say it improves flavor, some say there is no difference. Some question the safety of using ceramic. All the sub ohm tanks on of best sub ohm tank list, however, use organic cotton wicking.


There are 2 styles of airflow on sub ohm tanks.

  • Top

  • Bottom

Bottom airflow is best for flavor

as the air will come from directly underneath the coils but can be more susceptible to leaking if not used correctly.

Top air will give off less flavor but is virtually leakproof

. Some top air tanks channel the air under the coils internally hence increasing the flavour to be like bottom air. For the purpose of this list, there will be no true top air tanks due to the lack of good flavour.

What’s an RBA?

During the course of this list, you will hear that term a lot. An RBA deck is used as a coil head, however, you install your own coils and wick on it prior to using. It turns your tank into an RTA basically (Rebuildable Tank Atomizer) Some tanks come with this option in case you run out of or don’t want to buy coil heads anymore. Also, in the case that the manufacturer stops making coils for an older tank which could happen. Without an RBA, that would make the tank useless if it became outdated and no longer supported. It’s pretty rare that happens, however, as many manufacturers still make coils for tanks that are years old.

Juice Ratio

Ejuice comes in many options of VG/PG mixture. VG ( Vegetable Glycerin) is the thicker of the bases. It’s good for clouds and doesn’t have a throat hit. PG ( Propylene Glycol) is thinner and carries flavor a little better, but also gives the throat hit similar to smoking. Having the right mixture is essential to your tanks performance. For MTL tanks, the best mixture is a 50/50 mix. It provides the throat hit-like smoking and also makes the juice thin enough to wick properly. Using too thick of a juice in a MTL tank can cause it not to wick properly leading to dry hits and coils burning out too fast. 60/40 (VG/PG) is also acceptable.

For the best sub ohm tanks, the best mixture is 70/30 (VG/PG) but 60/40 and 80/20 are also acceptable (VG/PG). Max VG isn’t recommended as it could contain anywhere from 80-99% VG and be too thick to wick properly if it’s on the higher VG side, 50/50 isn’t recommended either as it can be too harsh in a sub ohm tank and could be too thin causing leaks.

Nicotine Strength

Ejuice also comes in many options of nicotine strength. While nicotine strength is preference, I will give you the basic guidelines. 1.5-6mg is a good optimal range for sub ohm tanks. Anything higher will be too strong to use as sub ohm tanks deliver more nicotine than MTL tanks. For MTL tanks, 12-24 is the good optimal range. Of course, everyone is different so find what works for you, and if you don’t need the nicotine at all, then feel free to buy 0MG nicotine for any tank.

Drip Tips

All sub ohm tanks have a drip tip. But not all drip tips are the same. There are 2 standard diameters of drip tips.

The 510 (smaller)


810 (larger)

Sub ohm tanks come in different heights as well. Some shorter than others. What’s good is this means more preference to the user. 510 and 810 tips can be replaced with any of the same size tips and are widely sold in many places. Some feature proprietary tips that can’t be replaced as easy. “Wide bore” refers to tips that have more air and are less restricted. Even tips of the same size (example 510) can have different levels of airflow due to being wide bore or not.
