Best Vape Tanks UK: MTL, Sub Ohm and All-Rounder Picks

The best vape tank is the one that fits your mod, suits your draw and takes coils you can buy again. This guide shortlists six tanks from Go Smoke Free's range and sets out their specifications side by side: three groups by draw style, then the checks that show if a tank will work on your device. To browse more of our range, see the mouth to lung tanks and the sub ohm tanks, or find a replacement in our vape coils range.

How These Tanks Were Chosen

The shortlist comes from published specifications and Go Smoke Free's range. It is not a ranking, and the "best for" labels describe fit, not position. Each tank had to meet three conditions, and replacement coil heads are linked wherever Go Smoke Free lists them:

• Live product page: the tank has a current Go Smoke Free listing.
• UK 2ml capacity: it is sold as the 2ml version required for UK sale.
• Coil data: coil resistance is listed, with a wattage range from the product or matching coil listing, so you can check them against your mod.

Specifications are as listed on each product page, with coil wattages taken from the matching coil listing where the tank page does not give them. Where a listing is unclear or contradicts itself, the figure is left out or described as approximate.

Best MTL Tanks

A mouth to lung tank pairs a tighter airflow with a higher-resistance coil and a low-wattage device. Both tanks here have 22mm bodies.

Tank	Diameter	Capacity	Coils (fitted, then spare)	Wattage	Fill
Aspire Nautilus 2	22mm	2ml	0.7Ω, 1.8Ω	18 to 23W (0.7Ω), 10 to 14W (1.8Ω)	Top fill (unscrew the tank protector)
Innokin Zenith D22 MTL	22mm	2ml	0.5Ω Plexus Z mesh, 1.6Ω	14 to 19W (0.5Ω), 10 to 14W (1.6Ω)	Twist-to-fill top cap

Aspire Nautilus 2: Best for a Classic, Low-Wattage MTL Draw

The bottom airflow ring has five settings from wide to narrow, and the product page says the tank is made for MTL use and that high VG e-liquid is not recommended. It is an older design: Vaping360's 2017 review found its airflow suited MTL and advised not going more than two or three watts above the 12 to 13W (1.8Ω) and 20 to 23W (0.7Ω) at which it worked best, because going further can overheat the mouthpiece and burn the coil. Replacement Nautilus 2 coil heads are listed, and the wider Aspire coils page covers the rest of the range.

Innokin Zenith D22 MTL: Best for a Mesh Coil in a Compact MTL Tank

The product page describes the 0.5Ω Plexus Z coil as the first MTL mesh-type coil, with a 1.6Ω coil as the spare for lower wattages and a 0.8Ω coil sold separately for a slightly warmer draw. Airflow adjusts with a twist ring at the base. The tank page gives no wattage range, but the coil listings rate the 0.5Ω Plexus Z at 14 to 19W and the 1.6Ω Z coil at 10 to 14W. The 0.5Ω coil is sold as Plexus Zenith coil heads, the 0.8Ω and 1.6Ω coils are in the Zenith coil heads pack, and more are on the Innokin coils page.

Best Sub Ohm Tanks

A sub ohm tank takes coils under 1Ω, a looser airflow and a higher-wattage device. The three tanks below differ mainly in diameter and in how wide a wattage window their coils cover. For the fundamentals, our guide to sub ohm tanks goes further.

Tank	Diameter	Capacity	Coils and wattage	Fill
Uwell Valyrian 2	27mm	2ml	0.32Ω single mesh, 90 to 100W; 0.14Ω dual mesh, 80 to 90W; 0.16Ω triple mesh, 90 to 100W; 0.15Ω quad, 100 to 120W	Hinged top cap, release button
FreeMax Mesh Pro (resin edition)	25mm	2ml	0.2Ω double mesh fitted, 60 to 90W; 0.15Ω single mesh spare, 40 to 70W	Push-back top cap
HorizonTech Falcon	25.5mm at base	2ml	0.15Ω mesh fitted, up to 70W; 0.2Ω spare, up to 80W	Quarter-turn top cap

Uwell Valyrian 2: Best for a High-Power Mod and a Choice of Coil Builds

Four FeCrAl coil options run from a 0.32Ω single mesh at 90 to 100W to a 0.15Ω quad at 100 to 120W, so the coil you fit sets the minimum power your mod needs. The page states the tank ships with 2ml of straight glass to meet UK requirements. Coils are listed as Valyrian 2 replacement coil heads, with more on the Uwell coils page.

FreeMax Mesh Pro: Best for a Wide Wattage Window

The resin edition's page gives an overall range of 40 to 110W, with the fitted double mesh at 60 to 90W and the spare single mesh at 40 to 70W, so it can run on devices that top out around 70W as well as stronger ones. Airflow comes from twin base intake ports with an adjustable resin ring, and the listing counts eight compatible coil formats. Spares are listed as Mesh Pro coils.

HorizonTech Falcon: Best for a Mesh Build at Moderate Power

The fitted 0.15Ω mesh coil is rated to 70W, the spare 0.2Ω to 80W, and the listing gives three adjustable airflow slots on the base and wicks of 70% cotton and 30% wood pulp. The connection is listed as 510 with a fixed positive pin, so confirm your mod accepts it. Replacements are listed as Falcon coil heads.

Best All-Rounder Tank

An all-rounder uses adjustable airflow to cover both draws. The tank below does it with a single coil type, so the airflow ring does the work.

Tank	Diameter	Capacity	Coils and wattage	Fill
Ample Firefox MTL/DL	24mm	2ml	Two 0.3Ω dual coils, 25 to 75W	Unscrew top cap

Ample Firefox MTL/DL: Best for One Tank Across Both Draws

The twist ring narrows the dual-channel top airflow for MTL and opens it for direct lung, and the product page suggests about 30W as an MTL starting point. At 0.3Ω the coil is lower in resistance than the 0.5Ω to 1.8Ω coils in the MTL picks above, so on MTL the tighter draw comes from the airflow setting, not the coil. The listing states the tank needs a mod with a 510 connector and 24mm of tank space. A tank built for both draws is a compromise, and a dedicated MTL or sub ohm tank will usually suit one draw more closely.

How to Choose the Best Vape Tank for Your Mod

Check four things before you order.

Check	What to confirm
Connection	The tanks above that list a connection use 510. Confirm the listing names yours.
Diameter	The tank must fit your mod's atomiser space. The Firefox listing, for example, asks for 24mm of tank space.
Wattage	Your mod's range should cover the coil's rated range. Run the coil inside it.
Coils	Check that replacement coils for the tank are in stock before you rely on it, and compare them in the vape coils range.

Vaping360's wattage warning for the Nautilus 2 applies to any coil: running past its rating can burn the coil. Tanks sold in the UK are limited to 2ml under regulation 36 of the Tobacco and Related Products Regulations 2016. On the device side, the Office for Product Safety and Standards, via Trading Standards, advises using the charger that came with your device and never charging a vape with a phone or tablet charger.

If you would rather build your own coils, see our rebuildable RTA tanks. For more on how tanks work, see our ultimate guide to vape tanks.

Which Tank Should You Choose?

Match the tank to your mod and your draw:

• Low-wattage mod and a classic MTL draw: the Aspire Nautilus 2, with a 0.7Ω coil at 18 to 23W or a 1.8Ω coil at 10 to 14W.
• Low-wattage mod and a mesh coil: the Innokin Zenith D22 MTL, with its 0.5Ω Plexus Z coil at 14 to 19W.
• Mod that tops out around 70W: the FreeMax Mesh Pro, whose spare coil is rated 40 to 70W, or the HorizonTech Falcon, whose fitted coil is rated to 70W.
• High-power mod of 80W or more: the Uwell Valyrian 2, whose coils run from 80 to 120W.
• One tank for both draws: the Ample Firefox MTL/DL, with coils rated 25 to 75W and about 30W as an MTL starting point.

FAQs

What is the difference between an MTL and a sub ohm tank?

An MTL tank uses a tighter airflow, a higher-resistance coil (0.5Ω to 1.8Ω among the picks above) and lower wattage. A sub ohm tank takes coils under 1Ω, opens the airflow and runs at higher wattage. Sub ohm describes the coil and the tank. How you inhale, mouth to lung or direct to lung, is a separate question of technique.

Can I use a sub ohm tank on a low-wattage device?

Only if the coil's rated range sits within what the device delivers. The fitted Falcon coil is listed up to 70W and the fitted Mesh Pro coil at 60 to 90W, while the Mesh Pro spare is listed at 40 to 70W. A device that tops out below the coil's rating will not drive it properly, so the coil's rating is the guide, not the tank's name.

Why are UK vape tanks limited to 2ml?

Regulation 36 of the Tobacco and Related Products Regulations 2016 sets a 2ml limit on tanks, a 10ml limit on refill bottles containing nicotine and a 20mg/ml nicotine strength limit. Every tank listed here is the 2ml UK version.

How do I know if a tank will fit my mod?

Match three figures first: the connection (510 on the tanks above that list one), the tank diameter against your mod's atomiser space, and the coil's wattage range against your mod's output. If any one is outside the listed range, choose a different tank or coil. The sub ohm tanks and mouth to lung tanks pages show the range, and each product page gives the diameter, connection and coil data.

Which e-liquid suits an MTL or sub ohm tank?

The MTL tanks here suit thinner liquid. The Nautilus 2 page says high VG is not recommended, and the Zenith coil listing says its 0.8Ω and 1.6Ω coils suit 50/50 or high PG liquids, so look at 50/50 e-liquid. The sub ohm tanks pair with thicker liquid: the Valyrian 2 listing bundles a high VG e-liquid and the Mesh Pro page points to the high VG range. Check the page of the tank you choose for its own recommendation.
