The tank holds your e-liquid and houses the coil, and whether you are after thick sub-ohm clouds or a tighter mouth-to-lung draw, the right one makes the difference. We stock proven tanks from Aspire, Vaporesso, Smok, OXVA and Innokin — including the Aspire Nautilus that so many MTL vapers stay loyal to — plus spare glass for when one takes a knock.
Match the tank to your kit first: sub-ohm tanks want a higher-wattage mod and high-VG shortfills, while MTL tanks pair with nic salts at lower power. Once you have it set up, you only ever swap the coil and the odd bit of glass. Sold individually, fast UK delivery,

Each tank uses its own coil platform. Geekvape Z Series coils do not fit Vaporesso tanks and vice versa. Always confirm the coil platform matches your tank before ordering replacements.
Sub-ohm tanks are designed for direct-to-lung (DTL) and restricted direct-to-lung (RDL) vaping, where e-liquid capacity, vapour volume and flavour intensity are prioritised over a tight draw. The Geekvape Zeus Sub-Ohm Tank 5 (£22.99 at VapeCity) is the current flagship in the Zeus range, with a 5ml capacity and top-fill design. It uses Z Series XM coils, which cover a mesh and dual-mesh range from sub-ohm DTL through to a tight RDL at the higher resistance end. The sealed top cap opens with a quarter-turn to fill without removing the tank from the device. The Zeus 5 is compatible with most 510-threaded box mods and advanced pod mods with a 510 adapter.
The Vaporesso iTank T Dual Mesh (£19.99 at VapeCity) offers the largest capacity in the VapeCity tank range at 8ml, using GTi dual-mesh coils in 0.2Ω and 0.4Ω configurations. The dual-mesh coil design increases the heated surface area relative to a single-mesh coil, improving flavour consistency with high-VG shortfill e-liquids at 40-80W. The iTank T uses a pull-and-fill top-fill mechanism and has adjustable bottom airflow. The Voopoo UForce X Tank (£14.99) uses UForce FT coils in a 5ml body, with a side-fill port under the top cap and adjustable bottom airflow. The UForce X sits between MTL and open DTL in draw resistance, covering the RDL range most suited to 50/50 blends at 10mg nicotine.
The Geekvape Zeus Sub-Ohm Tank (the predecessor at £16.99) uses the same Z Series coil platform as the Zeus 5 but with a 4ml capacity and an older coil range. Both Zeus models are coil-compatible with the Z Series XM Boost packs stocked at VapeCity. If you already own a Zeus coil stock, either tank generation uses the same coils. The Zeus 5 adds the larger capacity and a redesigned fill mechanism, while the original Zeus Sub-Ohm Tank delivers the same coil platform at a lower purchase price for the tank itself.

Choose a sub-ohm tank (Geekvape Zeus 5, Vaporesso iTank T, Voopoo UForce X) if: you use high-VG shortfill e-liquid at 3-6mg, vape at 40-80W, and prefer a warm, dense vapour with a loose draw. Choose an MTL tank (Innokin Prism range, Aspire Nautilus 3SR, Vaporesso XTank T) if: you use 20mg nic salt or 50/50 blend at 10-25W, prefer a tight draw that mimics a cigarette, or are in the process of switching from smoking. The Aspire Nautilus 3SR (£20.99) spans both categories with an adjustable airflow that covers both RDL and tight MTL on the same tank.
The Innokin Prism tank series is the most accessible range in the VapeCity tank lineup by price. The Prism T20S (£7.99) and Prism T18E (£8.99) are the entry-level options, both using the Prism T18 or T18E coil platform respectively and operating at 10-16W for tight MTL use with 20mg nic salt. The T18E Pro (£10.99) and T18 II (£9.99) add incremental refinements to the same coil-and-tank format. All four Innokin Prism tanks use a top-fill design with a fixed airflow calibrated for a tight, consistent MTL draw. They are best paired with 20mg nicotine salt in a 50/50 VG/PG blend at 12-16W. Innokin Prism coils use a dual coil layout rather than mesh, which provides a different vapour character from the mesh-dominant options in the sub-ohm category.
The Aspire Nautilus 3SR (£20.99) is the most versatile tank in the MTL section at VapeCity, with adjustable airflow that covers both restricted direct-to-lung and a tight MTL draw on the same unit. The adjustable airflow ring has distinct click positions so you can set a repeatable draw without readjusting each time. It uses Nautilus BVC coils, which is a long-standing Aspire platform available in multiple resistance options including 0.7Ω for RDL and 1.8Ω for tight MTL. The Nautilus 3SR is top-fill via a rotary cap. At 4ml capacity, it suits a full day of use on 20mg nic salt without refilling in most vaping patterns.
The Vaporesso XTank T (£13.99) uses the GTX coil platform, covering 0.8Ω for MTL at 12-25W through to 0.3Ω for RDL at 32-40W. This is the same GTX coil range used in the Vaporesso GTX One and GTX Two kits, so if you already stock GTX coils, the XTank T uses the same pack. The tank body holds 4ml and uses a top-fill system. The XTank T sits between the budget Innokin Prism tanks and the premium Nautilus 3SR in terms of coil range flexibility and build quality.
A sub-ohm tank uses coils below 1.0 ohm and is designed for direct-to-lung (DTL) or restricted direct-to-lung (RDL) vaping at 40-80W, using high-VG shortfill e-liquids at 3-6mg nicotine. An MTL tank uses coils at 1.0 ohm and above, designed for a tight draw that mimics a cigarette at 10-25W, using 20mg nic salt in a 50/50 blend. Both types are refillable vape tanks that use replaceable coils. The right choice depends on your preferred draw style and e-liquid type.
Most vape tanks use a 510 thread connector, which is the standard connection on box mods, tube mods and many advanced pod mods with a 510 adapter. Check your device for 510 compatibility before purchasing a standalone tank. Some pod kits use a proprietary magnetic connection rather than a 510 thread, so a 510 tank will not attach to these devices. If you are unsure, check the device specification or contact VapeCity.
The Geekvape Zeus Sub-Ohm Tank and Zeus Sub-Ohm Tank 5 both use Z Series XM (Boost) coils, which are the same coil platform used in the Aegis Legend 5 and some other Geekvape mods. Geekvape uses separate coil series for each kit family: Z Series for Zeus and Aegis Legend, B Series for Aegis Boost and Hero, and P Series for Aegis Prime. These series are not cross-compatible within the Geekvape range.
For most vapers using a tank with 20mg nic salt at MTL resistance, a 2-4ml tank is sufficient for a day of moderate use. At VapeCity, the Innokin Prism tanks and Aspire Nautilus 3SR are 4ml. For sub-ohm vaping with shortfill at higher wattage, a larger capacity reduces refill frequency: the Vaporesso iTank T at 8ml and the Geekvape Zeus 5 at 5ml cover heavier DTL/RDL use. EU TPD rules limit most UK tank sales to 2ml unless the tank has a larger included reservoir, so always check the actual fill capacity listed.
The Aspire Nautilus 3SR is the main tank at VapeCity that spans both MTL and RDL on the same body, using different Nautilus BVC coil resistances (1.8Ω for tight MTL, 0.7Ω for RDL) combined with adjustable airflow. The Vaporesso XTank T with GTX coils also spans 0.8Ω MTL through 0.3Ω RDL. Most other tanks are calibrated for either MTL or sub-ohm use. Swapping a 1.8Ω MTL coil into a sub-ohm airflow chassis will not produce a satisfactory result without adjusting the airflow too.
