Best Vape Tanks: A Buyer's Guide
Vape tanks are the bread and butter of vaping. Capable of holding up to 2ml of e-liquid and housing the coil that heats it, the tank is where the vapour actually gets made. This guide covers how a tank works, the difference between sub-ohm and mouth-to-lung tanks, and our current picks across both categories.
A note on how these picks were chosen: the tanks below are compared on specification, build quality and manufacturer-stated performance rather than weeks of first-hand testing. We're upfront about that distinction so you know exactly what you're reading.
How Does a Vape Tank Work?
A vape tank is typically made from glass or high-grade plastic to resist cracking, and is built around a few core parts. The coil sits at the heart of the tank and heats the e-liquid to create vapour. The mouthpiece, also called a drip tip, is where you draw that vapour in. Drip tips are usually a standard 510 connection, so you can swap between different mouthpieces to suit your preference.
Can You Adjust a Vape Tank?
Airflow is one of the biggest factors in how a tank actually vapes. Tanks with adjustable airflow let you balance a tighter draw, which sharpens flavour and feels closer to smoking, against a looser draw that produces bigger clouds. Where the airflow openings sit matters too: top airflow tends to reduce the chance of leaking and keeps flavour consistent, while bottom airflow directs air straight to the coil for a richer flavour profile.
Coil material affects flavour as much as airflow does. Mesh coils have a larger surface area and heat more evenly than traditional wire coils, generally giving a more intense flavour. The specific material, whether Kanthal, stainless steel or nickel, changes things further: some heat up faster, others last longer. Our full guide to vape coils goes into this in more depth if you want to understand it properly before choosing a tank.
Sub-Ohm vs Mouth-to-Lung Tanks: What's the Difference?
A sub-ohm tank runs a coil with a resistance below one ohm. It heats up faster and uses more e-liquid than a standard mouth-to-lung setup, and it's built for direct-to-lung vaping: a looser, more open draw that produces bigger clouds and pulls more vapour straight into the lungs rather than holding it in the mouth first. Because of the increased airflow and higher wattage involved, using a sub-ohm tank mouth-to-lung tends to feel harsh and can bring on coughing, so it's worth matching your tank type to how you actually intend to vape rather than mixing the two.
A mouth-to-lung tank is built the other way: higher resistance, more restricted airflow, and a tighter draw that's closer to the feel of smoking. This is where most vapers who've recently switched from cigarettes are most comfortable, and it's also what most beginner devices are set up for out of the box.
In the UK, tank capacity is capped at 2ml regardless of type, under the Tobacco and Related Products Regulations (TRPR), the UK's retained version of the old EU rules. That cap applies to both sub-ohm and mouth-to-lung tanks alike.
Our Current Picks
- Aspire Atlantis GT Tank
- Horizon Falcon Legend
- Geekvape Z Fli
- Voopoo Uforce-X
- Smok TF-D
- Vaporesso iTank 2
- Innokin Zlide
- Freemax Fireluke 4
1. Aspire Atlantis GT Tank
A well-regarded tank appreciated for its build quality and flavour production, making it a strong contender for sub-ohm vaping. It has an adjustable top airflow system, controlled by rotating the bottom airflow ring, designed to minimise leaks while maximising flavour retention.
The metal protective cover doubles as a style feature and an added layer of protection for the glass. The Aspire SE coils it supports come in 0.18, 0.3 and 0.35 ohm options. The drip tip is wide and curved for cloud performance, and the 510 connection is replaceable if you want to swap it for a different mouthpiece.
2. Horizon Falcon Legend
One of the more distinctive tanks on this list, built with bamboo fibre and wood pulp in its coils rather than the usual cotton, which Horizon says improves e-liquid absorption and distribution and extends coil lifespan.
Its top-fill system is designed to keep refilling simple and minimise spills, with every part of the tank removable for cleaning or maintenance.
The bottom-to-top airflow design is fully adjustable to personal preference. It's available in black, blue and stainless steel finishes.
3. GeekVape Z Fli Tank
Known for a leak-resistant design and strong flavour delivery.
The flip-top cap makes filling straightforward, a genuine point of difference from more fiddly top-fill designs, and the top airflow system routes air past the drip tip for consistent flavour on each draw.
It's built from durable materials typical of GeekVape's range, and uses high-grade mesh coils across a range of resistances for fast, even heating.
4. Voopoo Uforce-X
Built around triple airflow and compatibility with Voopoo's full PnP-X coil range, which spans mouth-to-lung through to sub-ohm use in one tank:
- 0.15 ohm (DTL): best around 60-80W
- 0.2 ohm (DTL): best around 40-60W
- 0.3 ohm (DTL or RDL): best around 32-40W
- 0.45 ohm (RDL or MTL): best around 26-32W
- 0.6 ohm (RDL or MTL): best around 18-23W
- 0.8 ohm (MTL): best around 12-16W
- 1.0 ohm (MTL): best around 10-13W
That range makes it one of the more versatile tanks here if you're not committed to one vaping style.
5. SMOK TF-D Subtank
Unusually for a SMOK tank, this one supports both mouth-to-lung and direct-to-lung styles rather than being built for DTL only, and takes a 510 connection compatible with most devices over 25W.
It has a top-fill design and customisable airflow via a twist mechanism. The Smok D coils use a dual mesh design, available in 0.15, 0.23 and 0.4 ohm resistances. Smok recommends pairing it with high-VG e-liquid, ideally 100% VG, to get the most from the mesh coils.
6. Vaporesso iTank 2
Built around Vaporesso's GTi mesh coil range, available in 0.2 or 0.4 ohm, covering both a looser, flavour-and-cloud-focused draw and a tighter, more restricted one. The Corex heating technology is Vaporesso's own coil design, intended to improve e-liquid distribution and flavour consistency.
Filling is straightforward: a button press opens the tank automatically, and it includes a self-cleaning function to help keep things running smoothly between deeper cleans.
7. Innokin Zlide
A long-running, reliable MTL tank, designed for a proper throat hit and a discreet amount of vapour rather than big clouds.
The sliding top-fill mechanism, which gives the tank its name, sits under the mouthpiece and helps prevent flooding the coil when you top up.
8. Freemax Fireluke 4
A stainless steel sub-ohm tank built around Freemax's own mesh coil range, which ships with a 0.15 ohm coil (rated 40-90W) and a 0.2 ohm coil (rated 40-80W) as standard, giving you a choice of two flavour and cloud profiles out of the box.
Freemax says its coil technology brings a meaningful improvement in flavour and heating speed over earlier Fireluke coils, though we haven't tested this ourselves to confirm it.
It uses a sliding top-fill design, comes apart fully for cleaning, and is available in black, stainless steel, silver and blue.
As with all UK-sold tanks, capacity is limited to 2ml under TRPR, regardless of the larger capacity sold in some other markets.

Frequently Asked Questions
What's the actual difference between a sub-ohm and an MTL tank?
Resistance and airflow. Sub-ohm tanks run below one ohm, use more open airflow, and are built for a looser direct-to-lung draw. MTL tanks run higher resistance with more restricted airflow, giving a tighter draw closer to smoking. Using one type for the other's intended style usually feels wrong, sometimes harshly so.
Why are UK vape tanks limited to 2ml?
It's a regulatory limit under the Tobacco and Related Products Regulations (TRPR), the UK's retained version of the original EU rules, and it applies to every tank sold here regardless of type or brand.
Does coil material actually make a difference to flavour?
Yes, though airflow and tank design matter too. Mesh coils generally deliver more intense flavour than traditional wire coils because of their larger surface area, and the specific metal (Kanthal, stainless steel, nickel) affects heating speed and durability as well as taste.
Can I use any coil in any tank?
No. Coils are designed for specific tanks or coil families (Aspire SE, GeekVape Z series, Voopoo PnP-X, and so on), so always check compatibility before buying replacements rather than assuming a coil will fit.

Health, safety and regulatory points are checked against named UK authorities such as the NHS and MHRA, and a product is only ever called "less harmful than smoking" where a UK authority says so. More about how he works, and the family story behind V2, is on Joe's author profile.
