Eleaf Atomizer Head (Pack of 5): What You Are Buying

The Eleaf Atomizer Head (Pack of 5) is a multipack of replacement heating coils for refillable Eleaf tanks and pod systems. It is a consumable accessory. There is no battery in the box, no tank, no e-liquid and no charging cable. What you receive is five sealed atomiser heads, each one a small cartridge of resistance wire and cotton wicking inside a metal housing, designed to push into the base of a compatible Eleaf tank or into the coil seat of a compatible pod. When one head wears out, you pull it, drop in the next, prime it and carry on with the same device you already own.

This listing covers a family of three variants. They are separated by resistance and by the power range each head is built to run at, so the correct pick depends on how you vape and on which tank you own rather than on personal taste alone. Coil heads are not universal. A head that looks identical to the one in your tank can still have a different thread, a different seal diameter or a different air-flow path, and any of those mismatches leads to leaks or poor vapour. Read the compatibility line on the product page, then check the markings on the head you are replacing. Eleaf prints the resistance and a recommended wattage window on the shell of most of its heads, and you should match both.

Why a pack of five? Because a coil is a wear part and because buying in multiples is usually the cheaper way to keep a tank running. A typical daily vaper changes a head every one to three weeks, so five heads cover roughly two to four months of use. Having spares in a drawer also means a burnt-out coil never leaves you without a working setup on a Sunday evening when the shops are shut.

Eleaf is an established hardware maker whose tanks, pods and mods have been sold in the UK for many years, and its heads are among the more widely stocked replacement coils in British vape shops. That availability matters in practice: you can find them easily, and you can compare prices between retailers without hunting for obscure parts. This page walks through performance, flavour, build, power, coil technology, nicotine choice, fitting, troubleshooting, value and honest comparisons with competing coil systems, so you can decide whether this pack suits your device.

• Product type: replacement atomiser heads for refillable tanks and pods

Performance and Vapour Delivery

A coil head decides most of what you notice at the mouthpiece: how quickly it fires, how much vapour it makes, how warm that vapour is and how stable the draw feels from the first puff to the last. The heads in this range are built around resistance values that Eleaf pairs with particular styles of vaping, and the numbers tell you a lot before you ever fit one.

Lower-resistance heads, typically anything below about 0.3 ohm, are designed for direct-to-lung inhaling at higher wattage. They heat a larger wick surface, draw more power from the battery and produce a denser, warmer cloud. They also use e-liquid faster, so a small tank empties sooner than it would with a higher-resistance head. Higher-resistance heads, around 0.5 ohm and up, run at lower wattage, sip less liquid and suit a tighter draw closer to what a cigarette feels like. They make less vapour, but that is the point for many people stepping away from smoking, because the throat hit is firmer and the battery lasts longer between charges.

Ramp-up time is short with either type once the cotton is properly saturated. Expect vapour within a fraction of a second of pressing the button or taking a draw. If a head takes noticeably longer to respond, the usual cause is a dry wick rather than a faulty coil, and priming correctly fixes it nearly every time. That is covered in the fitting and troubleshooting sections below.

Consistency over the life of the head is the real test. A new coil tastes and performs at its peak for the first few days, then drifts gradually as residue from sweeteners builds on the wire and the cotton darkens. You should see steady output for somewhere between one and three weeks of regular use. Heavy use of dessert or sweet fruit liquids shortens that, while tobacco, menthol and drier fruit profiles are kinder to the cotton. Running a head above its stated wattage range is the quickest way to cut its life to a few days, so treat the printed range as a limit rather than a suggestion.

• Low resistance (around 0.15 to 0.3 ohm): bigger clouds, warmer vapour, faster liquid use, needs a capable battery
• Mid resistance (around 0.3 to 0.6 ohm): balanced vapour and flavour, flexible across many devices
• Higher resistance (around 0.6 ohm and above): tighter draw, lower power, longer battery life, suits nicotine salts

These are general ranges for the category rather than a promise about each specific variant, so use the figure printed on your chosen head as the final word.

Flavour Profile and What Affects It

A coil does not have a flavour of its own, but it shapes how your e-liquid tastes more than most people expect. The wire material, the surface area of the heating element, the quality of the cotton and the temperature the whole assembly reaches all change what reaches your tongue. This is why the same bottle can taste crisp in one tank and muddy in another.

Fresh heads give the cleanest flavour, and that first stretch of use is when subtle notes show up: the cooling edge in a menthol, the sharpness in a citrus, the difference between a red apple and a green one. Eleaf heads are generally tuned to give rounded flavour rather than a harsh, over-toasted edge, particularly when run in the lower half of the printed wattage window. Push the power to the top of the range and flavour tends to flatten while the vapour gets hotter. Dropping the wattage a few steps almost always brings definition back.

As a head ages, you will notice the change before the coil actually fails. Sweet liquids leave a caramelised film that dulls fruit notes first, and then everything starts to taste faintly alike. A slightly burnt or bitter background taste means the cotton has started to scorch and the head is at the end of its useful life. Do not try to vape through it. A tired head is cheap to replace, and the unpleasant taste is a poor trade for squeezing out a few more days.

Liquid choice matters as much as the coil. Thin, high-VG blends suit low-resistance heads with wide wicking ports. Thicker, sweeter liquids can slow wicking on small high-resistance heads and lead to dry hits if you chain vape. Nicotine salt liquids, which are usually thinner and run at higher strengths, pair naturally with the higher-resistance heads and lower wattages. If you have just switched head type and the flavour seems off, change one thing at a time: first the wattage, then the liquid.

• Run new heads in the lower to middle part of the stated power range for the cleanest taste
• Expect sweet and dessert liquids to dull the flavour sooner than fruit, tobacco or menthol
• Replace a head as soon as a burnt or flat taste appears, rather than waiting for a complete failure
• Rinse the tank thoroughly when changing liquids so old flavours do not carry over into a new head

Design and Build Quality

These heads are small, so the build details are easy to overlook, but they are the details that decide whether the head seals properly, wicks reliably and lasts its full life. A typical Eleaf head has a metal outer shell, usually stainless steel, that protects the coil and cotton and provides the electrical contact at the base. Inside sits the heating element wrapped around or pressed against organic cotton, and around the shell are a set of wicking ports that let e-liquid flow from the tank into the cotton. At the base you will find a silicone seal or o-ring set and a centre pin that makes contact with the battery connection.

The pressed-in construction used on this style of head is standard across the industry, and consistency between heads in a pack is generally good. When you open a pack of five, all five should look the same: clean metal, even seals, no bent pins, no cotton hanging out of the ports and no residue on the sealing surfaces. If one looks different from the rest, do not fit it. Contact the retailer instead, because a visibly damaged head is a defect, not a quirk.

The sealing surfaces deserve a little care when you handle them. Silicone rings need to sit flat and undamaged for the head to hold pressure and avoid leaks. Avoid touching the cotton, and never squeeze the shell to test it. Keep unused heads in the original packaging until you need them, away from heat, direct sunlight and damp. Cotton absorbs moisture and odours from the air, so a loose head stored in a pocket or a drawer of strong-smelling items can pick up a taste that lingers for the first few puffs.

On compatibility, treat the head as a precision part. Eleaf uses different base designs across its tank lines, and the shell diameter, thread or push-fit style and air-flow pattern vary. The product listing names the compatible range, and the resistance and series name are printed on the head itself. If your old head has a series name such as EC-M, EC-N, GT, GTi or HW and you are unsure what you need, read it off the old head and match it. Do not try to force a head into a tank it was not designed for.

• Metal shell and sealed base protect the coil and ensure a reliable electrical connection
• Silicone seals prevent leaks when seated correctly
• Resistance and series markings on the shell make like-for-like replacement straightforward
• Inspect every head on opening and reject any with damaged seals or bent pins

Power, Battery and Charging Considerations

The heads themselves have no battery and no charging port, but they do dictate how hard your device has to work, which in turn affects how often you charge. Battery drain scales with power: a head that wants 60 watts empties a battery noticeably faster than one that runs at 15 watts. If you are choosing between two variants in this pack family, remember that the lower-resistance head will usually shorten the gap between charges, and the higher-resistance head will stretch it.

Eleaf pod systems and compact tank kits often use built-in batteries somewhere in the range of 400 mAh to 1,500 mAh, with larger mod-style devices using one or two replaceable 18650 cells rated at around 2,500 to 3,500 mAh each. As a rough guide, a built-in battery of around 1,000 mAh paired with a 0.8 ohm head at low power can last a full day for a moderate vaper, while the same capacity paired with a 0.15 ohm head at 60 watts may only last a couple of hours of steady use. These are indicative figures, so check the specification of your own device rather than relying on them.

Charging habits matter for battery health and for safety. Use the cable that came with your device or a reputable replacement, plug it into a standard USB charger rather than a fast-charge brick unless the manufacturer says it is fine, and do not leave a charging device unattended overnight on a soft surface. If you use removable 18650 cells, use an external charger and keep spare cells in a case rather than loose in a pocket with keys or coins. A swollen, hot or damaged battery should be taken out of use at once.

When batteries or devices reach the end of their life, they should not go in the household bin. Lithium cells can cause fires in refuse lorries and recycling plants. UK shops that sell vaping equipment and batteries are expected to offer take-back, and many household waste recycling centres and supermarket drop-off points accept small electricals and batteries. Ask at the counter or check your local council website for the nearest drop-off point. Spent coil heads are small and mostly metal and cotton, and your local authority will say whether to treat them as general waste or small electrical items.

• Higher resistance: lower wattage, longer battery life, gentler on small built-in batteries
• Lower resistance: higher wattage, shorter battery life, suits larger batteries and removable cells
• Always: charge on a hard surface, use a suitable cable and recycle spent batteries at a proper drop-off point

Coil and Wicking Technology Explained

Understanding what is inside a head helps you buy the right one and spot problems early. Every atomiser head does the same job: it passes electrical current through a length of resistance wire, which heats, vaporises the e-liquid held in the cotton wick next to it and releases the vapour into the air path. The differences between head types come from how the wire is arranged, what it is made of and how the cotton is packed.

Eleaf has used several coil constructions over the years. The older EC-style heads use round wire wrapped around a cotton wick, which is simple, cheap and reliable. Mesh-based designs replace the wire coil with a flat sheet of perforated metal that is rolled or folded against the cotton, increasing the contact area so that heating is more even and flavour is more consistent. Newer GT and GTi style heads use a multi-coil or ceramic-reinforced structure designed to cope with higher power. Which of these you hold depends on the variant in this pack, so check the series name on the head.

Resistance is measured in ohms, and it is set by the wire gauge, the material and the length of the heating element. By Ohm's law, a lower resistance lets more current flow for a given voltage, which means more power and more heat. That is why a 0.15 ohm head can happily run at 60 watts while a 0.8 ohm head would struggle to use more than about 20. The wattage range printed on the head is the window in which the wire heats the cotton at the right rate without scorching it.

Most Eleaf heads use kanthal or stainless steel wire, which are both well suited to wattage mode on a standard device. Some variants may be compatible with temperature control if the wire is nickel or stainless steel. Check your device manual before trying temperature control, because using it with the wrong wire type will give inaccurate readings.

The wick is organic cotton in the great majority of heads of this kind. It draws liquid from the tank by capillary action. If the wick is too tight, liquid arrives slowly and dry hits follow. If it is too loose, liquid floods the chamber and gurgles. Manufacturers tune this at the factory, which is why you should never tamper with a head to try to improve it.

• Round wire heads: simple and economical, good for everyday use
• Mesh heads: larger heating surface, more even flavour, often faster heat-up
• Multi-coil or reinforced designs: built for higher wattage and heavier use
• Resistance and wattage range are the two numbers that matter most when choosing

Choosing Nicotine Strength for Your Coil

Nicotine strength and coil resistance work together, and choosing the wrong pairing is a common reason people feel a new setup is harsh or unsatisfying. A low-resistance head at high power produces a large volume of vapour per puff, so each puff delivers a lot of nicotine if the liquid is strong. A higher-resistance head at low power produces much less vapour, so you need a stronger liquid to get the same effect.

In the UK, the legal maximum nicotine strength for e-liquids is 20 mg/ml, which is 2 percent. That limit applies to refillable e-liquids and, before they were banned, applied to disposable vapes too. Single-use disposables can no longer be sold in Great Britain as of June 2025, so a refillable system with replaceable heads, like the one these heads belong to, is now the main route for anyone who wants a vape device. UK rules also cap bottle size at 10 ml for nicotine e-liquid and tank capacity at 2 ml, which is why you will see 2 ml tanks and 10 ml bottles across the market.

As a starting point, with a higher-resistance head (about 0.6 ohm and above) at low power, nicotine salt liquids of 10 to 20 mg/ml are the usual choice, because salts are smoother at high strength. With a mid-resistance head (about 0.3 to 0.6 ohm), 6 to 12 mg/ml freebase or 10 mg/ml salt tends to work. With a low-resistance head (below about 0.3 ohm) at higher power, most people use 3 mg/ml freebase or lower, because the vapour volume delivers plenty of nicotine, and anything stronger becomes harsh quickly.

If you are moving from cigarettes, it is better to start slightly stronger than you think you need than to go too low and end up smoking again. If you are an existing vaper and your throat feels scratchy, step the strength down, lower the wattage or both. If you are not a smoker or vaper, a vape is not a product you should start using. Nicotine is addictive, and e-cigarettes are meant for adults who currently smoke or vape. Nobody under 18 can legally buy these products in the UK.

• Higher resistance, low power: nicotine salt, around 10 to 20 mg/ml
• Mid resistance: around 6 to 12 mg/ml freebase or 10 mg/ml salt
• Low resistance, high power: around 0 to 3 mg/ml freebase
• UK legal cap: 20 mg/ml, with 10 ml maximum bottles and 2 ml maximum tanks

Who These Heads Are For, and Who Should Skip Them

This pack is aimed at existing users of compatible Eleaf hardware who want to keep their tank or pod running at a lower cost per head than buying singles. If you already own a tank that takes this head, buying five at once makes sense. If you are about to buy your first device, start with the hardware and then choose the head style that suits it, because a pack of coils is not something you can use on its own.

It suits adult smokers who have switched to vaping and are settled on a hardware setup. People in that group tend to change heads regularly, notice the difference between a fresh and a tired coil, and value the convenience of spares in the drawer. It also suits people who run more than one device, since a multipack lets you keep each tank stocked without a trip to the shop every time one burns out.

It is a good fit for anyone who wants to move away from throwaway products. With single-use disposables banned in Great Britain, a refillable system with replaceable heads is both the legal and the more economical route, and it produces far less waste. A tank that takes five heads in a pack can run for the best part of a year before the tank itself needs replacing.

It is a poor fit in a few situations. If you do not know which Eleaf model you own, do not order until you have checked, because heads are not interchangeable and returns on mistaken orders are an annoyance for everyone. If you want a device that needs no maintenance at all, a sealed pre-filled pod system may suit better than a refillable tank. If you do not currently smoke or vape, you should not start. And if you are buying for someone under 18, do not: it is illegal to sell vapes to under-18s and illegal to buy them on their behalf.

• Good fit: adult vapers with a compatible Eleaf tank or pod who want spare heads
• Good fit: smokers who have switched and want a cheaper, lower-waste setup than disposables
• Poor fit: anyone who has not confirmed their device model and head series
• Poor fit: non-smokers, and anyone under 18

How to Fit, Prime and Run In a New Head

Fitting a new head properly is the single biggest factor in how long it lasts and how good it tastes. Most early failures come from skipped steps rather than faulty coils. The process takes about ten minutes including waiting time, and it is the same for most heads in this family.

• Step 1, empty and unscrew. Switch the device off or lock it, remove the tank, and pour out any remaining e-liquid. Unscrew the base or pull the pod apart, depending on your hardware.
• Step 2, remove the old head. Unscrew or pull out the used head. Wipe the seat dry with a clean tissue and check that the o-rings are intact.
• Step 3, inspect the new head. Check the seals, pin and shell for damage. Do not touch the cotton.
• Step 4, prime the cotton. Put four to six drops of e-liquid directly onto the exposed cotton through the wicking ports, then let it soak in for a few moments.
• Step 5, seat the head. Push or screw it firmly into the base, ensuring it sits flat. Do not overtighten.
• Step 6, fill the tank. Fill with e-liquid up to the maximum line, not over it, and avoid blocking the air-flow hole or central tube.
• Step 7, wait. Leave the tank upright for at least five minutes so the cotton can finish saturating. Ten minutes is better for thick liquids.
• Step 8, run in. Start at the bottom of the wattage range printed on the head. Take a few gentle puffs without firing, then increase the power gradually over the first several puffs.

Skipping the wait is the most common mistake. If the cotton is not fully wet when you first fire the coil, the dry fibres scorch and leave a burnt taste that never fully goes away. A burnt cotton head cannot be rescued, so be patient with the first fill.

In daily use, avoid chain vaping, which draws liquid faster than the cotton can replace it. Keep the tank at least a third full, because running it nearly empty starves the wick. When you change liquids, flush the tank first and prime the head again if you are changing to a markedly different flavour. If the device allows it, lock the button when it is in a bag or pocket so it cannot fire dry by accident.

Store spare heads in their packaging until needed, and rotate the stock so older packs are used first.

Troubleshooting Common Problems

Most problems with a replacement head fall into a small number of categories, and most have simple fixes. Work through the cause in order, starting with the easiest.

Burnt or acrid taste. Almost always caused by dry cotton, too much power or an old head. Check that the tank has liquid above the wicking ports, lower the wattage to the bottom of the stated range, and prime the head again. If the taste persists after a fresh fill and a rest, the cotton has scorched and the head needs replacing.

Weak or flat flavour. Check the head's age first. After a week or two, sweet liquids coat the wire and flavour fades gradually. A new head and a thorough clean of the tank usually restore it. If the head is new, try a lower wattage, because overheated vapour tastes flat.

Leaking. Check the silicone seals are seated and undamaged, that the tank is not overfilled and that the head is firmly screwed in or pushed home. Leaks around the base after a new head is fitted often mean an o-ring has shifted. Reseat the head. If a leak continues, check for hairline cracks in the tank glass or plastic.

Gurgling or spitting. Usually caused by condensation or flooding. Blow gently through the mouthpiece to clear the air path, wipe the drip tip, and make sure the tank is not overfilled. Thick liquids in a high-wattage head can also spit, so try a lower power setting.

Device says check atomiser, short or no coil. The device cannot read the head. Unscrew it, check that the centre pin is clean and not pressed in, and reseat the head. Wipe the contact on the device with a dry cotton bud. If a second head gives the same message, the fault is probably in the device connection rather than the coil.

Dry hits. The wick is not drawing fast enough. Slow down between puffs, top up the tank, lower the wattage and let the head rest. Dry hits on a brand-new head usually mean it was not primed or rested long enough.

Head dies within days. Common causes are very sweet liquids, running above the stated wattage, chain vaping or no priming. Change one habit at a time to find the one responsible.

• Always prime and rest a new head before firing it
• Keep the tank above a third full
• Stay within the wattage range printed on the head
• If a fault appears across several fresh heads, suspect the device or the tank rather than the coils

Value for Money and Running Costs

Value with a coil pack comes down to cost per head, cost per week of use and whether the heads last as long as they should. A five-pack almost always costs less per head than singles, and it removes the small hassle of reordering often. Prices vary between retailers and over time, so always compare the per-head figure rather than the pack headline.

As a worked example of the logic, suppose you change a head every two weeks. Five heads then cover ten weeks of use, which is roughly two and a half months. Over a year you would use about 26 heads, or between five and six packs. If you changed every week because you vape heavily or run sweet liquids, that doubles. The pack price divided by five, multiplied by the number of heads you use per year, gives your annual coil bill. Compare that against the weekly cost of the cigarettes you replaced and the gap is usually very large in the vaper's favour.

Three things stretch the life of a head and therefore improve value. Prime properly each time, so the cotton is never fired dry. Run within the printed wattage range, and drop a few watts if the flavour seems harsh. Choose liquids that are not extremely sweet, or alternate with tobacco, menthol or fruit flavours to give the wire a rest. These habits can easily add a week to a head's life, which across a year means several packs saved.

Compare against disposables, which have been banned for sale in Great Britain since June 2025, and against sealed pre-filled pods. A refillable tank with replaceable heads has a higher upfront hardware cost but a much lower cost per vaping hour, and it generates a fraction of the waste. Used heads are small, but they still count towards waste, so dispose of them according to your local council guidance and send batteries and devices to a proper drop-off point rather than the bin.

Buy from a retailer you trust. Counterfeit coils exist in the market, and a fake head that looks identical can use poor-quality cotton or wire and, in the worst cases, behave unpredictably. A head that is much cheaper than every other listing deserves suspicion. Buying from an established UK retailer, with clear delivery and returns terms, protects you against the risk and gives you someone to contact if something is wrong.

• Cost per head is the number to compare, not pack price alone
• Good priming and sensible wattage extend life more than any other habit
• Refillable systems cost less per week than disposables or pre-filled pods over time
• Buy from reputable UK sellers to avoid counterfeits

How Eleaf Heads Compare With Other Brands' Coils

Coils are brand-specific, so the real comparison is between ecosystems rather than individual parts. When you buy a tank, you are also choosing which heads you will buy for the next year or two. Here is how the main options compare, in fairness to each.

Eleaf. Strengths are wide availability, a broad range of resistances and several head families that cover both tight mouth-to-lung and open direct-to-lung vaping. Heads are usually priced at a mid-market level, and spares are easy to find in UK shops. The downside is that Eleaf has used many different head series across its tanks over the years, which makes it important to check the series name before ordering.

Vaporesso. Vaporesso's GTX and similar mesh coils are well regarded for even flavour and are common in UK shops. The range is broad and the heads suit many of the brand's tanks and pods. Prices are in the same general bracket as Eleaf, and the choice between them comes down to which hardware you prefer rather than a clear quality gap.

Smok. Smok's coil range is large and long-established, covering pods such as the Nord and RPM families and bigger tanks. Selection is deep and prices can be competitive, but with so many series the same compatibility care is needed.

Uwell. Uwell's Caliburn pod coils and Crown tank coils are popular with those who want tidy pod devices. The pod-coil ecosystem is tightly controlled, so heads are easy to match but you are tied to one brand.

Aspire and Geekvape. Both have well-liked mesh and wire coils and active communities. Availability is good for their main ranges, but check that your retailer stocks the specific series.

Third-party and clone coils are cheaper and widely sold, but quality varies. Some are fine, and some use poorer cotton or inconsistent resistance. If you choose them, buy from a reputable seller and expect to experiment. For most people who simply want a reliable replacement, original Eleaf heads for an Eleaf device are the safest option, and the pack of five keeps the cost per head reasonable. None of these brands is categorically better than the others. The right choice is whichever one matches the tank you own, the way you vape and the budget you want.

• Match the head to the tank, since coils are not cross-compatible between brands
• Compare cost per head and availability when choosing a new device
• Original heads cost a little more than clones but reduce the risk of poor performance
• No single brand is clearly ahead; choose by hardware fit and vaping style
