Overview of the Aspire Nautilus 2S replacement coils 5 pack

The Aspire Nautilus 2S replacement coils 5 pack is a multipack of spare mesh coil heads made for the Aspire Nautilus 2S family of refillable vape devices. The coil head is the small consumable part that sits inside the pod or tank, soaks up e-liquid through its cotton wicking and heats it to make vapour. It is the one component on a refillable kit that wears out on a regular schedule, which is why anyone who keeps a Nautilus 2S going for more than a few weeks ends up buying coils far more often than any other part.

Buying five in one go is the practical way to handle that. Rather than waiting for a single coil to fade and then hunting for a replacement, you keep a small stock in a drawer and swap the moment flavour starts to drop. For a typical daily vaper, five coils cover roughly two to three months of use, depending on the e-liquid, the power setting and how often you vape. Heavy users will get through them faster, and occasional users may find a pack lasts a good part of the year.

This page walks through everything worth knowing before you order and after the parcel arrives, from compatibility checks and coil technology through to nicotine strength, fitting, troubleshooting, value and how these coils compare with alternatives from other brands. It is written for UK vapers and assumes you are 18 or over, since selling vaping products to under-18s is illegal in the UK.

Which devices these coils fit and how to check before you order

Compatibility is the single most common reason a coil order goes wrong, so it is worth a minute of checking. These coils are designed for the Aspire Nautilus 2S system. Aspire has released a long run of Nautilus products over the years, including the original Nautilus, the Nautilus 2, the Nautilus GT, the Nautilus X, the Nautilus Prime and the Nautilus 2S, and the coil heads are not universally interchangeable across all of them. Some models share a coil family, while others use a different base, a different resistance range or a different locating shape.

The simple rule is to match the name on the coil pack to the name on your device. If your kit is a Nautilus 2S, these are the coils to look for. If you own an older Nautilus tank, check which coil it takes before assuming anything carries over.

A few practical checks before you order:

• Look at the coil you are replacing. Most coil heads have the series name and resistance printed on the metal shell or the side. Compare that with the product title on this page.
• Check the resistance. Coils in the same range are often sold in more than one ohm value. The resistance should be shown in the listing details, and it should suit the way you vape, as covered in the performance section below.
• Do not force a coil. A correct coil seats with light, even pressure and a firm stop. If it will not seat, stop and re-check the model rather than pushing harder.
• Do not mix ranges. Coils from other product lines, even ones that look similar, may fit loosely or not at all and can cause leaks or a poor electrical connection.
• Compare the related listings. There are three related listings in this product family on our site, which usually differ by resistance or pack configuration. Look at each one before adding to your basket.

If you are unsure which Aspire device you own, the model name is normally printed on the base of the device or on the original box. If you are still stuck, get in touch with the model name and we can confirm which coil you need before you buy.

Coil and mesh technology explained

The defining feature of this coil is the mesh heating element. Traditional vape coils are built from a length of round wire wrapped around a cotton wick. A mesh coil replaces that wire with a thin, perforated sheet of resistance metal, usually a stainless steel alloy, formed into a curved shape and pressed against a cotton wicking surface. The sheet carries a regular grid of tiny holes, and e-liquid soaks through the cotton onto the mesh across a much larger contact area than a single wire can offer.

That larger surface area has several practical effects:

• Faster, more even heating. More of the e-liquid is touching a hot surface at the same moment, so the coil reaches vaping temperature quickly and vapour is produced consistently from the start of a draw.
• Fuller flavour. Even heating tends to give a rounder, more complete flavour than a hot spot on a single wire. Sweet and fruity notes in particular come through clearly.
• Efficient use of power. A mesh coil can produce satisfying vapour at modest wattage, which is part of why compact devices such as the Nautilus 2S use this design.
• Lower dry-spot risk. The cotton touches the mesh over a wide area, so the wicking has more room to keep up with demand, provided the e-liquid is not too thick.

Resistance is measured in ohms. A lower number lets more current flow, which means more heat and more vapour at a given power setting. A higher number gives a cooler, tighter draw that sits closer to the feel of a cigarette. Mesh coils made for compact pod and tank systems commonly sit below one ohm, and the exact figure for the version you are buying is shown in the listing details. Always run a coil inside the wattage range printed on its pack. Pushing it harder does not improve flavour, it simply burns the cotton sooner and shortens the coil's life.

The cotton itself is just as important as the metal. It acts as the wick, drawing e-liquid in from the reservoir and holding it against the mesh. Fresh cotton is dry, which is why priming matters (covered in the how-to section). Over time, sweeteners and flavour compounds in the e-liquid build up as a thin deposit on the mesh and cotton. That residue, often called gunk, is what eventually dulls flavour and signals that it is time to swap the coil.

Performance and vapour delivery

Because coils are consumables, their performance is measured in days and millilitres rather than the puff counts you see quoted for disposable vapes. As a rough guide, a mesh coil used at sensible power with a standard 50/50 or 60VG e-liquid will often give around one to three weeks of consistent flavour, which for many people works out to somewhere between 15ml and 30ml of e-liquid passing through the coil. Treat those figures as a guide rather than a promise, because the real number depends on your habits and your juice.

With a fresh coil installed you can expect the following:

• Quick response. Mesh warms up almost immediately, so there is little delay between pressing the button or drawing and getting vapour.
• Smooth, warm vapour. The even heating gives a consistent temperature across the draw, which many users find gentler on the throat than a hot-spot coil at the same power.
• Reliable output across the tank. Performance stays steady from a full tank down to a low one, unlike some coils that start to struggle as the liquid level drops.
• A mouth-to-lung or restricted style of draw. The Nautilus 2S is a compact system and the coil is built for a controlled draw rather than huge clouds, which suits former smokers and anyone who prefers a more discreet vape.

What affects how long the coil keeps this performance? The biggest factors are e-liquid sweetness, power setting and vaping pattern. Heavily sweetened dessert and candy liquids leave residue faster than lighter fruit or menthol blends. Running the device at the top of the coil's power range heats the cotton harder and shortens its life. Chain vaping, taking many puffs in quick succession, gives the cotton less time to re-saturate and is a common cause of a burnt taste.

You will usually notice a coil is on its way out through a gradual change rather than a sudden failure. Flavour flattens first, then vapour may thin a little, and eventually a slightly bitter or burnt note appears. When that happens, swap the coil rather than trying to push through, because a tired coil makes even a good e-liquid taste poor.

Flavour profile and what to pair with these coils

A coil does not have a flavour of its own. What it controls is how faithfully your e-liquid is rendered. A clean, fresh mesh coil is close to neutral, which means it lets the character of the liquid come through rather than adding a metallic or toasted note. That is one reason people who change e-liquid flavours often like to keep a few spare coils on hand.

Mesh heating is particularly good at bringing out layered flavours. Here are seven e-liquid styles that tend to work well with a coil like this, together with what to expect:

• Blue raspberry and other sweet-sharp fruit. Bright, tangy notes stay crisp rather than turning muddy.
• Strawberry kiwi and mixed berry blends. Multiple fruit layers remain distinguishable as the coil heats evenly.
• Mango and peach. Tropical and stone-fruit flavours come across juicy and rounded, though they are sweet, so expect to change the coil a little sooner.
• Menthol and mint. Cooling flavours are delivered cleanly and with consistent intensity, and they leave less residue than sugary profiles.
• Tobacco. Lighter tobacco blends keep their dry, papery character, while rich, dark tobacco blends are rendered smoothly rather than harshly.
• Cola and fizzy drink styles. The sharp, spiced top notes hold their definition.
• Custard, vanilla and bakery desserts. These taste full and creamy, but they are the most likely to gunk up a coil, so be ready to replace it at the first sign of fading.

On thickness, a balanced e-liquid such as a 50/50 PG/VG mix, or a blend up to around 60 to 70 percent VG, is a sensible match. Very thick high-VG liquids can wick slowly through the cotton and cause dry hits, particularly when the tank is nearly empty.

If you move between very different flavour families, for example from strong menthol to a creamy dessert, you may notice flavour carry-over, sometimes called ghosting. The cotton holds on to traces of what went before. The cleanest solution is a fresh coil when you make a big switch. This is another reason the 5 pack is handy: you can dedicate a coil to a flavour family without worrying about running out.

Design and build quality

A coil head looks simple but is a small assembly of several parts. The outer shell is metal and houses the mesh element and cotton, with an electrical contact at the base that connects to the device and a ring of seals that stop e-liquid escaping around the sides. Small intake holes let e-liquid flow in from the reservoir to the cotton, and the open top leads the vapour up through the mouthpiece. Everything is sized to a tight tolerance, because even a slight mismatch between the coil and its seat can cause a leak or poor contact.

Points worth looking at when your coils arrive:

• Intact packaging. The coils should be sealed or clearly unopened, with no signs of previous use. A genuine product from a reputable UK retailer will arrive in tidy, consistent packaging.
• Clean metalwork. The shell should be free from dents, scratches that expose bare metal in odd places, or discolouration.
• Visible, evenly seated cotton. Through the inlet holes you should see clean white or off-white cotton, not stained or compressed fibres.
• Fully fitted seals. The sealing ring should sit evenly around the coil with no gaps or twisting.

Aspire is one of the longer-established names in refillable vaping hardware, and the Nautilus line has been a familiar sight in UK vape shops for years. That track record is a factor when you are choosing coils, because a manufacturer's own replacement parts are built to the same tolerances as the device they go into. By contrast, unbranded or counterfeit coils can vary in resistance, wicking quality and seal fit, which is a recipe for leaks and inconsistent vapour.

A five-coil pack is also compact. It slips into a pocket, a bag or a drawer, and the individual coils are small enough that carrying a spare while you are out and about takes no effort. Keep the unused coils in their original packaging until you need them, away from heat, direct sunlight and moisture.

Battery and charging considerations

The coils themselves contain no battery and are not charged. They do, however, interact with the battery in your Nautilus 2S device, so a few points are worth knowing. The Nautilus 2S is built around a rechargeable lithium-ion battery in the region of 1,000mAh, which is a typical size for a compact refillable system. Check your device manual for the exact figure and charging specification.

How coil resistance affects battery life:

• A lower resistance coil draws more current to reach a given power level, so it will drain the battery faster than a higher resistance coil at the same wattage.
• A fresh coil heats and vaporises e-liquid efficiently, so you may find battery life feels slightly better right after a swap than it did with a worn-out coil that needed longer draws.
• A burnt or very gunked coil can reduce efficiency, which is one more reason to replace it promptly.

Good charging habits keep the battery healthy for longer:

• Use the charging cable supplied with the device, or a good quality USB cable, plugged into a standard 5V adapter from a reputable brand.
• Avoid leaving the device charging unattended for long periods, especially overnight on soft furnishings.
• Do not charge a device that is hot, damaged or has visibly swollen. Stop using it and recycle it safely.
• Keep the device away from coins and keys in a pocket or bag, which can bridge the charging contacts and cause a short circuit.

If the device does not fire after a coil change, it is far more likely to be a connection issue than a battery fault. Remove the coil, check that the base is clean and dry, reseat it and try again. Never put a damaged lithium-ion battery in household waste or kerbside recycling. Take it to a battery or electrical recycling drop-off point, which many UK supermarkets and household waste recycling centres provide.

Nicotine strength guidance for use with these coils

The coils do not contain nicotine, but the strength of the e-liquid you put through them has a large influence on your experience, so it is worth choosing deliberately. In the UK, the Tobacco and Related Products Regulations 2016 cap nicotine e-liquid at 20mg/ml (2 percent) and restrict bottle sizes to 10ml. Refillable tanks are limited to 2ml. That 20mg limit is the same ceiling that applied to disposable vapes before single-use disposables were banned from sale on 1 June 2025, which is a large part of why many former disposable users have moved to refillable kits like the Nautilus 2S.

Mesh coils deliver warm, efficient vapour, so the nicotine reaching you per puff can feel stronger than the number on the bottle suggests. A sensible way to choose is to start lower than you think you need. These are general guides, not medical advice:

• Heavier smokers (around 15 or more cigarettes a day): Nicotine salt e-liquid at 10mg to 20mg is the usual starting point, as salts are smoother at higher strengths. If 20mg feels harsh, step down to 12mg or 10mg.
• Moderate smokers (around 5 to 15 a day): Nicotine salts at 10mg to 12mg, or freebase nicotine at around 6mg to 12mg, are common choices.
• Light or social smokers: Freebase at 3mg to 6mg, or nicotine salts at around 5mg to 10mg, is usually enough.
• Long-term vapers reducing their nicotine: Step down gradually, for example from 12mg to 6mg to 3mg, giving yourself a couple of weeks at each stage.

Nicotine salts feel smooth even at higher strengths, while freebase has a firmer throat hit and tends to be used at lower strengths. Because mesh coils warm the liquid evenly, freebase at higher strengths can feel sharp, so many users pair these coils with salts or with lower freebase strengths.

Signs that your strength is too high include dizziness, nausea, headaches, a racing heart or a harsh throat hit. If any of these occur, stop vaping, drink some water and drop to a lower strength next time. Nicotine is addictive, and the NHS advises that vaping is far less harmful than smoking but is not risk-free. If you do not currently smoke, you should not start.

Who these coils are for, and who should skip them

These replacement coils are a sensible purchase for a specific group of people. They are not a general-interest product, and being clear about that saves you money and a returned parcel.

Who they suit:

• Owners of an Aspire Nautilus 2S. If you already have the device and need to keep it running, this is the part you will buy most often.
• Adult smokers who have switched to vaping. The controlled draw of a compact mesh system suits people moving away from cigarettes who want something familiar rather than a cloud-focused setup.
• Former disposable users. With single-use disposables no longer sold in the UK, a refillable system with replaceable coils gives similar convenience with less waste and a lower ongoing cost.
• People who like to stock up. If you dislike running out mid-week, five coils in a drawer remove the problem.
• Flavour-focused vapers. If you rotate between e-liquid styles, spare coils let you keep each flavour family clean.

Who should skip them:

• Anyone under 18. Sale and supply of vaping products to under-18s is illegal in the UK, and we do not sell to them.
• Non-smokers and never-smokers. Vaping is a harm-reduction tool for adult smokers, not a recreational habit to pick up.
• Anyone without a compatible Nautilus 2S device. These coils are not a universal fit, so do not order them for a different kit.
• People who want a throw-away, no-maintenance product. A refillable kit means refilling, priming and swapping coils. If that sounds like too much effort, a refillable system may not suit you.
• High-power cloud chasers. These coils are built for a compact, controlled draw, not for large volumes of vapour at high wattage.
• Pregnant or breastfeeding women and people with heart or respiratory conditions. Speak to a GP or a stop-smoking service before using nicotine products.

If you are a smoker looking to quit, local NHS stop-smoking services offer free support and can be combined with vaping as part of a plan. Ask your GP or pharmacist about what is available near you.

How to fit, prime and use your new coil

Fitting a coil takes a couple of minutes, but the steps matter. Skipping the priming stage is the most common cause of a burnt first puff and a ruined coil. Follow this routine each time you swap:

• Step 1: Switch the device off. If it has a lock or off function, use it, and take care not to press the button while handling the parts.
• Step 2: Separate the pod or tank from the battery section. Empty any remaining e-liquid into a clean tissue or back into the bottle.
• Step 3: Remove the old coil. Depending on the design, it will either unscrew or pull out with a gentle twist. Check that the sealing ring comes out with it rather than staying in the tank.
• Step 4: Rinse and dry the tank or pod. Use lukewarm water, dry it fully and allow a few minutes of air drying, since any water left behind will cause spitting and gurgling.
• Step 5: Seat the new coil. Push or screw it in firmly and evenly until it stops, making sure the seal is flat and nothing is twisted.
• Step 6: Prime the coil. Put a few drops of e-liquid directly onto the cotton through the inlet holes, then fill the tank or pod. Do not overfill beyond the max line.
• Step 7: Wait. Leave the device standing upright for at least five to ten minutes so the cotton can saturate fully.
• Step 8: Start gently. Take a few short, easy puffs at the lowest comfortable power, then work up to your usual setting over the next few minutes.

Never press the fire button without e-liquid in the tank. Firing a dry coil, called a dry burn, scorches the cotton instantly and gives a harsh, unpleasant taste that does not go away. It can also damage the coil permanently.

Disposing of used coils. A spent coil is small electrical waste. Do not put it loose into kerbside recycling or leave it where children or pets could reach it. The Recycle Your Electricals website has a postcode search for local drop-off points, and many vape shops and household waste recycling centres accept vape components. Check what your local site takes before you go. Any batteries or devices should be taken to a battery or electrical recycling point and never placed in general waste.

Troubleshooting common coil problems

Most coil issues have a simple cause and a quick fix. Run through the list below before assuming a coil is faulty.

• Burnt taste straight after fitting. The coil was almost certainly not primed long enough. Let it rest for another ten minutes, take gentle puffs and avoid chain vaping. If the burnt taste persists after several minutes of careful use, the cotton may already be scorched and the coil should be replaced.
• Weak or flat flavour. This is the classic sign of a coil reaching the end of its life. Gunk has built up and is blocking e-liquid from reaching the mesh. Replace the coil. If the coil is new, check that you have not over-diluted the flavour by switching to a different e-liquid or lowering the power too far.
• Gurgling or spitting. Usually caused by a coil that is not fully seated, water left behind after rinsing, or an overfilled tank. Dry everything, reseat the coil and keep the e-liquid below the max line.
• Leaking from the base or air holes. Check that the sealing ring is sitting flat, that the coil is fully tightened and that the tank was not filled to the brim. Avoid squeezing the tank when the device is in your pocket, and store it upright when you can.
• No vapour or the device will not fire. Take the coil out, wipe the electrical contacts with a dry cloth, and reseat it. If your device shows a coil or atomiser warning, the connection is probably imperfect. Try a different coil from the pack to rule out a single faulty unit.
• Hard or restricted draw. Check the airflow slot or hole is not blocked and that the mouthpiece is clear of residue. Condensation or thick e-liquid can also restrict airflow.
• Dry hits that appear when the tank is low. The cotton is not receiving e-liquid fast enough. Refill earlier, use a thinner e-liquid, and give the device a few seconds between puffs.
• Coil dies within a few days. Review your e-liquid and your power. Very sweet liquids, high power and chain vaping are the three most common causes of short coil life.

If you have tried these steps and still suspect a manufacturing fault, keep the coil, its packaging and your order number. Contact us with a description and a clear photo, and we will look at it under our returns policy.

Value for money and how these coils compare with alternatives

A coil's value is best measured as cost per week of use rather than cost per unit. If a coil gives you around two weeks of reliable vaping, a five-coil pack covers roughly ten weeks. Multipacks are normally priced below the cost of five single coils, so buying five at once is almost always cheaper per coil than topping up one or two at a time, and you avoid the delivery cost of repeated small orders. Current pricing is shown on this page, and it can change, so check the live price before you buy.

Compared with single-use disposables, a refillable system is generally cheaper to run over time. A disposable is thrown away after a few days of use, taking its battery and electronics with it, whereas a Nautilus 2S keeps the device and replaces only the coil. That also makes it a lower-waste choice, as long as used coils and the device itself are recycled properly at the end of their life.

How do these coils stack up against rival ranges? Here is an even-handed comparison:

• Voopoo PnP coils. The PnP range is very widely stocked and comes in a broad choice of resistances, which suits people who want to experiment with different power levels. It belongs to a different device ecosystem, so it is not a like-for-like swap, but it is a fair benchmark for pricing and variety.
• Vaporesso GTX and GTi coils. Another mainstream mesh range with plenty of options. Vaporesso devices have a strong following, so replacement coils are easy to find. Again, the coils are specific to their own devices.
• SMOK Nord and RPM coils. These suit users in the SMOK ecosystem and offer a range of mesh and regular coil options. They are competitively priced but, as with the others, are not designed for the Nautilus 2S.
• Unbranded third-party coils. Cheaper sticker prices can look appealing, but quality control is inconsistent, resistances can differ from what is claimed, and fit can be loose. A badly fitting coil costs you far more in leaked e-liquid than you save on the coil.

The honest summary is that Aspire coils are not the cheapest on the market and are not the most varied, but they are a dependable match for the device they are designed for, and a manufacturer-made coil in the right pack size gives you predictable performance. If you already own a Nautilus 2S, the question is not really which brand to pick but how many coils to buy at once, and a five-pack is a sensible answer for most people. If you are weighing up a new device and coil ecosystem, compare the price and range of coils across the brands above, as running costs add up over a year.
