Vape Tanks Guide

What Are Vape Tanks?

A vape tank is the part of your e-cigarette or mod that holds your e-liquid and contains the coil which vaporizes it. In most devices, the tank sits on top of the battery, which is the pen-like part on older designs and the bigger, usually box-shaped part on modern devices.

Types Of Vape Tanks

As mentioned, there are many different types of vape tanks available, which have been condensed into something easily to digest below:


This type of tank is most commonly used with starter kits, as it is simple to use. One of the main reasons new vapers prefer this is because it is much less fiddly than other tanks. Plus, they are much cheaper. Most clearomisers use high resistance coils as well as a restricted airflow. This makes them ideal for mouth to lung vaping.


Regular tanks are designed to allow people to simply make the switch from smoking to vaping. They produce a more moderate amount of vapour, demand less power from your vape kit, and generally use coils with a resistance of 1.0ohm and above.

Regular vape tanks are perfect for anyone who wants something that can mimic the sensation of smoking, is easy to maintain, and uses less vape liquid whilst in use.


Sub-ohm vape tanks (or sub tanks) are built for power and vapour. They produce a much larger amount of vapour, require more powerful e-cigs to activate the coils housed within, and generally use resistances below 1.0ohm.

Large tanks are great for those who want more vapour and greater vaping satisfaction, and are often used as an upgrade from a regular one.


Rebuildable vape tanks are aimed at vapers who want to advance to the most complex vaping options available. Most rebuildable vape tanks require powerful e-cig mods, produce the most vapour and will commonly use coils 0.5ohm and below. You can build your own coils or install premade options to better suit your vaping style.

Rebuildable tanks are perfect for advanced cloud chasing, and once mastered, provide what some believe to be the ultimate vaping experience.

Types of Tanks

Vape Tank Diameter

It is important to pick the right tank diameter to match your battery to make sure your setup looks well paired.

With vape mods (or box mods), the diameter allowance tends to be a larger, allowing a greater variety of tanks to be used. You can still use a tank with a smaller diameter, but it might look a little out of place compared to the overall look and feel of the device itself.

If you happen to use a large tank which has a bigger diameter than the battery you are using, then this will cause something called ‘overhang’. Although this does not mean the tank won’t work, it is not a great look.

It is worth noting that virtually all vape tanks use the same connection (called 510) which is compatible with 99% of all e-cig batteries. The only exceptions to this rule would be bespoke magnetic connections for certain models, and something called an ‘eGo’ connection, which is an older style connection used on pen style batteries, with the Vapouriz FUSE tank being one example.

Top Or Bottom Filled Vape Tanks

When choosing a vape tank you can select from with a bottom filled vape tank or a top filled vape tank. Each has their own distinct benefits.

Bottom Filled Vape Tanks

Bottom filled tanks need to be removed from the battery in order to be topped up. This may seem more inconvenient than top filling, but it does have its perks. Some advanced bottom fill tanks also feature a lock to prevent the e-liquid from spilling out when the coil is removed. They are also less likely to get damaged as the filling port isn’t exposed. Bottom filled tanks are a good choice for most people, and are quite commonly found with many different vape kits.

  • More protection against fall damage.
  • Less likely so spill e-liquid.

  • Not as convenient.
  • More likely to leak.

Top Filled Vape Tanks

Top refill systems are quick and convenient. You don’t have to remove the tank from your battery, and they are available in different forms such as screw tops, sliding tops and flip tops. This method quickly reveals the filling hole for simple refilling at home or on the go. Top filled vape tanks are a good option if you don’t want to remove anything to refill, or if it is inconvenient to do so.

  • Can be refilled without removing it from the device.
  • Less likely to leak.

  • More likely to get damaged when dropped

Vape Tanks Air Flow

A tank’s airflow can either be adjustable, fixed, regular, airy or open. Each of these can have a massive impact on your vaping experience.

  • Adjustable airflow can be fully tweaked in order to find the perfect draw for you.
  • Fixed airflow cannot be adjusted, but they are usually designed to hit a sweet spot for a majority of vapers.
  • Regular airflow is usually quite restricted, and mimics the sensation of smoking. This option is perfect for both new and regular vapers.
  • Airy tends to be more open than regular, and can produce an increased amount of vapour with higher powered e-cigs.
  • Open airflow has little to no resistance at all, making it ideal for vapers who want to create large clouds of vapour at high wattages.

Best Vape Tanks

New vapers use regular tanks or clearomisers as they offer the easiest experience. Plus, the coils and airflow offer a similar experience to smoking, making the transition easier. Experience vapers prefer large tanks designed for sub ohm vaping. They are more complicated to use, but once you know what you're doing they offer a wider range of options to customise your experience.

However, the best tank depends entirely on what kind of vaping experience you want to have. If you’re looking for a standard vape which mimics the sensation of smoking, then you should choose a regular tank. If you’re after something with a little more ‘oomph’ then consider purchasing a sub-ohm tank.

Once you have a decent understanding of both regular and sub tanks, but want to enjoy the maximum amount of vapour and flavour, then you should consider trying an advanced rebuildable tank with an open airflow.

Which Vape Liquid For My Vape Tank

This is an important one to get right, but if you take a look below, we have provided some direction to help you choose the right vape liquid for you.

If you have decided to buy a regular tank, then this would be best paired with a vape liquid containing between 10-18mg (1.0% - 1.8%) of nicotine. Nic salts would also be suitable for use in this type of tank. Due to the lower power of this type of tank, a weaker strength might fail to satisfy those nicotine cravings.

If you have chosen to go for a sub-ohm vape tank, then anything from 6mg (0.6%) nicotine or lower would be ideal. Using anything higher may provide you with too much nicotine than you are used to having.

Should you go for the rebuildable option (RDA, RDTA etc), then the best nicotine strength would be 3mg (0.3%) or lower if you happen to mix your own vape liquid. We would advise avoiding the use of high strength nicotine in this type of tank to ensure a satisfying vape experience.

If you do happen to choose a higher nicotine option, then this would be better than choosing something too low. You can vape less often with a higher strength until your next e-liquid order.
