Tank Coils
This collection holds 104 replacement tank coils covering mouth to lung tanks, sub ohm tanks and the pod tanks that sit between them. Coils from Aspire, Innokin, Freemax, Lost Vape, Nevoks and iJOY are stocked here in mesh and round wire builds. Coils are consumable, so every tank in daily use needs a fresh one every week or two.
The single most important thing on this page is fitment. A coil is engineered for one tank family and nothing else. Thread size alone is not enough. Height, wicking port position and base seal all have to line up, so ordering by the exact name of your tank is the only reliable method.
Coils are family specific
Manufacturers group coils into families rather than making one per tank. Aspire Nautilus coils have carried across several generations of the Nautilus tank, which is why that family is still one of the most widely stocked mouth to lung coils in the country. Innokin's Z coil family is shared across tanks in the Zenith and Zlide lines. Freemax mesh coils are grouped by series rather than by individual tank.
What you cannot do is move between families. Aspire Cleito, Cleito Pro and Cleito EXO coils are three separate parts despite the shared name. A Nautilus coil will not seat in a Nautilus X. If the tank name on the coil packet does not match the tank in your hand, it is the wrong coil.
Reading the numbers on a coil
Resistance
Resistance is printed on the coil in ohms and defines the style of vaping it is built for. Anything above 1.0 ohm is a mouth to lung coil, running at low power with a tight cigarette style draw. Anything below 1.0 ohm is a sub ohm coil, built for a direct to lung draw with open airflow and much more vapour. The 0.6 to 1.0 ohm band sits in between and suits restricted direct to lung vaping.
Wattage range
Most coils carry a recommended range printed on the side. Start at the bottom of it and work up. Running above the range burns the cotton and shortens coil life dramatically. Running well below it produces a muted, cool vape that tastes thin. The printed range is the manufacturer's tested window rather than a formality.
Mesh against round wire
Round wire is the traditional coil, a wire wrapped into a spiral around the wicking material. Mesh replaces that with a perforated strip of metal, giving a larger and more even heating surface. Mesh ramps up faster, heats the cotton more evenly and generally lasts longer at a given wattage, which is why it now dominates sub ohm coils and most modern MTL coils too. Round wire still has a following among vapers who prefer a slower build up.
Matching the coil to your e-liquid
The coil dictates the liquid rather than the other way round. A coil above 1.0 ohm wants a 50/50 PG to VG blend, which in the UK means a 10ml bottle of nicotine salt or traditional freebase e-liquid at up to 20mg per ml. The wicking ports on these coils are small and a thick high VG liquid will not travel through them fast enough.
A sub ohm coil below 1.0 ohm needs a high VG shortfill, typically around 70/30, at a low nicotine strength of 0mg to 6mg. Thin 50/50 liquid in a sub ohm coil floods the chamber and leaks out of the airflow. Getting this pairing wrong is the most common reason a brand new coil fails within a day.
Priming a new coil properly
Priming is the difference between a coil that lasts a fortnight and one that tastes burnt on the second puff. Drip e-liquid directly into each wicking port until the cotton looks darkened rather than white. Screw the coil in, fill the tank and then leave it standing for at least five minutes. Ten is better on a high VG liquid. Take three or four draws with the device switched off to pull liquid through, then start at the lowest wattage in the range and work upwards over the first tank.
Skipping that wait is the most common cause of a coil ruined on day one. Cotton cannot be un-burnt.
How long a coil lasts and what shortens it
One to two weeks is the normal expectation for a tank in daily use. Sweeteners are the main thing that moves that figure.
Sucralose in dessert, candy and soft drink flavours caramelises onto the coil at temperature and forms a dark crust that blocks the wick. A heavily sweetened liquid can halve coil life. Dark bakery and custard blends do the same. Menthol, light fruits and unsweetened tobacco blends are far kinder and can double the interval between changes.
Wattage matters too. Running at the top of the range all day wears the cotton faster than sitting in the middle of it. Chain vaping without letting the wick reload gives dry hits that scorch the cotton permanently.
Knowing when to change it
The signs are consistent. Flavour goes dull or takes on a burnt edge. Vapour production drops even though nothing else has changed. The draw feels harsher at the back of the throat. Some tanks start spitting as the wick loses its ability to hold liquid. Once any of these appear, no amount of cleaning brings the coil back. Coils are sealed units that are not designed to be rebuilt.
Buying coils sensibly
Coils are almost always sold in packs of three or five, which is the correct way to buy them. Keeping one pack ahead of yourself removes the problem of a dead device on the day a coil fails. Check coil availability before committing to a new tank too, since a discontinued family strands an otherwise good atomiser.
UK rules, delivery and advice
Vaping products are sold to adults aged 18 or over only. Nicotine e-liquid sold in the UK is capped at 20mg per ml, bottles containing nicotine at 10ml and tanks sold containing nicotine liquid at 2ml. UK delivery is free on orders over £20. If you are not certain which coil your tank takes, the team can identify it on 07827 210361 between 8.30am and 4.00pm.
Tank coil questions answered
How do I find out which coil fits my tank?
Match the coil to the exact tank name, including any suffix such as Pro, Plus, Mini or X. Coils are engineered for one family, so the height, the wicking port position and the base seal all have to line up. The name is normally printed on the base of the tank or on the coil currently fitted.
Are coils interchangeable between brands?
No. Coils from one manufacturer will not fit another manufacturer's tank. Even within a single brand the families are separate. Aspire Cleito, Cleito Pro and Cleito EXO coils are three different parts despite the shared name. Some ranges do share coils across several tanks, such as the Aspire Nautilus family and the Innokin Z family. That is decided by the manufacturer rather than by the fitting.
What resistance coil should I use?
It depends on the draw you want. A coil above 1.0 ohm is a mouth to lung coil for a tight cigarette style inhale at low wattage. A coil below 1.0 ohm is a sub ohm coil for direct to lung vaping with open airflow and much more vapour. The 0.6 to 1.0 ohm band sits between the two and suits a restricted direct to lung draw.
What is the difference between mesh and round wire coils?
Round wire is a spiral of wire wrapped around the wick. Mesh is a perforated strip of metal that presents a larger, more even heating surface to the cotton. Mesh ramps up faster, heats more evenly and usually lasts longer at the same wattage. Round wire still appeals to vapers who prefer a slower, warmer build up of vapour.
How do I prime a new coil?
Drip e-liquid into each wicking port until the cotton darkens, fit the coil, fill the tank and then leave it standing for at least five minutes. Allow ten on a thick high VG liquid. Take three or four draws with the device switched off to pull liquid through, then begin at the lowest wattage in the printed range and work upwards. Rushing this step is the usual cause of a coil that tastes burnt on the first day.
How long should a tank coil last?
One to two weeks in daily use is normal. Heavily sweetened dessert, candy and soft drink flavours contain sucralose that caramelises onto the coil and can halve that. Menthols, light fruits and unsweetened tobaccos are much kinder. Running at the very top of the coil's wattage range also shortens its life.
Why does my new coil taste burnt straight away?
Usually one of three things. It was not primed and left to soak before the first draw. The wattage was set too high for the printed range. The e-liquid does not suit the coil. Thick high VG liquid in a mouth to lung coil above 1.0 ohm cannot wick fast enough, which dries the cotton and scorches it permanently.
Can I clean a coil instead of replacing it?
Not usefully. Tank coils are sealed units with cotton inside, so rinsing removes some residue from the metal without restoring the wick. Once flavour has gone dull or burnt the coil has reached the end of its life. Coils are sold in packs of three or five for that reason. Keeping a spare pack ahead avoids being caught out.
