Innokin Tanks & Rebuildables
Innokin tanks have a particular reputation among UK vapers, built almost entirely on mouth to lung performance. The Zenith line in particular is the tank most often recommended to people who want a cigarette like draw with proper flavour behind it. This collection holds 22 Innokin tanks and rebuildables, covering MTL tanks, a sub ohm tank, pen tanks and one rebuildable atomiser, with prices from £9.99.
Every tank here uses a standard 510 thread, so it will fit any regulated mod or pen with a 510 connection. What varies is the draw style, the coil family and the capacity. Those three things decide whether a tank suits the way you vape, so the sections below deal with each in turn.
Mouth to lung tanks
A mouth to lung tank has a narrow airflow inlet and a tight chimney, so vapour is drawn into the mouth before being inhaled. Coils are high resistance and wattage stays low, typically 12W to 20W. The Zenith range is the benchmark here. The Zenith 2 at £16.99 and the Zenith Minimal at £17.99 both offer fine airflow control, top filling and a draw that closes down to a genuinely tight cigarette style inhale. The Plex tank is £19.99.
Pen tanks
The Prism tanks are the simpler end of the line, designed to sit on Innokin Endura pens rather than on a box mod. The Prism T20 and Jem tanks are £9.99, the Prism T18II and Endura Apex Prism S tanks £10.99 and the T18E Pro £11.99. These use fixed or lightly adjustable airflow with a straightforward high resistance coil.
Sub ohm and restricted direct lung
The Z-Force DL/RDL sub ohm tank at £16.99 covers the other side of the range. Sub ohm tanks use coils below 1.0 ohm with wide open airflow and higher wattage, producing far more vapour on a direct to lung draw. They want a high VG shortfill at 3mg or 6mg and will get through liquid several times faster than an MTL tank.
Rebuildables
The Ares Finale RTA at £19.99 is the only rebuildable in the collection. An RTA is a rebuildable tank atomiser. It replaces the pre made coil with a deck you build yourself, wrapping your own wire and threading your own cotton. The Ares line is designed around mouth to lung building, which means a single coil deck with a tight chimney.
Rebuildables are not a beginner purchase. You need an ohm reader or a mod that reads resistance accurately, a basic tool kit and an understanding of what a short circuit looks like before you fire one. What you get in return is a running cost of pennies and complete control over resistance and wicking.
Coils and cross compatibility
Innokin runs a small number of coil families rather than a different coil for every tank, which makes reordering simpler. The Zenith and Z series tanks share the Z coil family. The Prism pen tanks share Prism coils. Check the coil family named on the tank listing rather than assuming, because a coil that threads in but seals badly will leak.
Capacity and the 2ml rule
A tank sold in the UK for use with nicotine e-liquid cannot hold more than 2ml. That is why every Innokin tank sold here ships with a 2ml glass regardless of what the tank is capable of in other markets. The cap is a legal requirement rather than a design decision, so it applies across every brand equally.
Getting the best from an Innokin tank
Prime every new coil. Drip liquid into the wicking ports until the cotton is visibly wet, fit the coil, fill the tank and leave it standing for five minutes before the first draw. Start at the bottom of the printed wattage range and step up until the flavour peaks. Keep the tank above a quarter full to avoid dry wicking.
Cleaning and maintenance
Tanks benefit from a strip down every few weeks. Empty the tank, take the sections apart and rinse everything except the coil in warm water. Dry thoroughly before reassembly. Check the O rings while you have it apart, since a perished seal is the usual cause of a tank that has started leaking for no obvious reason.
Buying Innokin tanks in the UK
Vaping hardware is sold to adults aged 18 and over and orders are age checked before dispatch. UK delivery is free on orders over £20, which most tanks in this collection clear on their own. For help matching a tank to a mod you already own, the team is on 07827 210361 between 8.30am and 4.00pm.
Innokin tank questions answered
Will an Innokin tank fit my mod?
Yes, provided the mod has a standard 510 connection, which almost every regulated mod and vape pen does. The other thing to check is diameter. A tank wider than the top of your mod will overhang, which looks awkward but does no harm. Innokin Prism tanks are designed for Endura pens specifically.
Which Innokin tank is best for mouth to lung vaping?
The Zenith family is the usual recommendation. The Zenith 2 and Zenith Minimal both offer fine airflow adjustment that closes down to a genuinely tight cigarette style draw, top filling and access to the Z coil range. If you want something simpler for a pen, the Prism T20 or T18II tanks do the same job at a lower price.
What is an RTA and should I buy one?
An RTA is a rebuildable tank atomiser. Instead of a pre made coil you fit a deck and build your own coil from wire, then wick it with cotton yourself. The Ares Finale RTA in this collection is a mouth to lung design. It is not a starting point. You need a mod that reads resistance accurately and a working understanding of coil building.
Why are all these tanks only 2ml?
UK regulations cap the capacity of any tank sold for use with nicotine e-liquid at 2ml. Every tank sold here therefore ships with a 2ml glass, even where the same model is supplied with a larger bubble glass in other countries. The limit applies to every brand equally.
Which e-liquid should I use in an Innokin tank?
Match the liquid to the coil. A coil above 1.0 ohm is mouth to lung and wants a 50/50 blend, which in the UK means a 10ml nic salt or freebase bottle at up to 20mg per ml. A coil below 1.0 ohm is sub ohm and needs a high VG shortfill at 3mg or 6mg. The Z-Force is the sub ohm option here.
How do I stop a new coil tasting burnt?
Prime it properly. Drip e-liquid directly into the wicking ports until the cotton is soaked, fit the coil, fill the tank and leave it standing upright for five minutes. Take a few draws without firing, then start at the bottom of the coil wattage range. Keeping the tank above a quarter full also helps.
Why has my tank started leaking?
The usual causes are a worn O ring, a coil that has not been tightened fully or filling the tank right to the top. Strip the tank down, check the seals for splits or flattening and replace any that look tired. Make sure the coil is seated squarely rather than cross threaded.
