OXVA Unicoil 0.2Ω (Pack of 5): what it is and why it matters

The OXVA Unicoil 0.2Ohm (Pack of 5) is a set of five replacement coil heads from OXVA, the hardware brand behind the Xlim pod range and the Origin line of tanks and pod mods. A coil is the consumable heart of any refillable vape: it holds the heating element and the cotton wick, it is the part that actually turns your e-liquid into vapour, and it wears out long before the battery, the tank or the device body do. Buying coils as a five-pack is how most regular vapers make sure they never find themselves with a dead coil on a Sunday evening and nothing to swap in.

This particular pack is the 0.2Ω (200 milliohm) version. In practical terms that means a low-resistance, sub-ohm coil designed for direct-to-lung (DTL) or restricted direct-to-lung (RDL) vaping. It is built to be paired with a mid-power device, a relatively open airflow, and a thicker, high-VG e-liquid at a low nicotine strength. If you are used to a tight, cigarette-style draw, this is a different experience, and we will be honest throughout this page about who it suits and who it does not.

Here is what you are getting in the pack:

  • Five pre-built Unicoil replacement heads, so there is no wrapping, wicking or building by hand
  • A rated resistance of 0.2Ω, a sub-ohm coil intended for lung-inhale vaping
  • A cotton-based wick, which is the standard approach for coils in this class
  • A formfactor intended for OXVA hardware that takes Unicoil heads, which you should confirm against your own device before ordering

It is worth being clear about what a coil is and is not. A coil is an accessory. It contains no nicotine, no e-liquid and no battery, and on its own it does nothing. It only works when it is seated in a compatible tank or pod, filled with a suitable e-liquid, and powered by a compatible battery. Because it is sold alongside nicotine products, this item is for adults aged 18 and over only.

The rest of this guide covers specifications, performance, flavour, build quality, power and battery considerations, nicotine strength, who the coil is for, how to fit and prime it, how to troubleshoot problems, and how it compares on value with the alternatives. We have written it for UK vapers, so the legal and practical notes reflect UK rules rather than anything imported from another market.

Specifications and what the numbers actually mean

Coil listings are full of numbers, and not all of them are equally useful. Here are the ones that matter for the OXVA Unicoil 0.2Ω, with an explanation of what each means in day-to-day use.

  • Resistance: 0.2Ω. Resistance describes how much the coil resists the flow of current. Lower resistance means more current flows at a given voltage, which means more heat and more vapour at a given setting.
  • Pack size: 5 coils. Each coil is a separate, sealed unit that you rotate in when the previous one loses its flavour.
  • Vaping style: DTL / RDL. A 0.2Ω coil is designed for a lung inhale, where you draw vapour straight into the lungs rather than holding it in your mouth first.
  • Power window: coils in the 0.2Ω class are typically used somewhere in the region of 40W to 65W, with the flavour sweet spot usually in the middle of the range printed on the coil packaging. Treat the figure on your pack as the authority, because it is specific to the Unicoil head.
  • Intended e-liquid: a high-VG blend, commonly 70VG / 30PG, at a low nicotine strength. Thin, high-PG juice can be drawn through the cotton faster than it can be replaced, but a thick blend can lag if the wick holes are small, so a balanced 60 to 70 percent VG liquid is a safe starting point.

The relationship between watts, volts, ohms and amps is worth a minute of your time, because it explains why a 0.2Ω coil feels so different from a 1.0Ω one. Using Ohm's law, a 0.2Ω coil fired at 40W sees roughly 2.8V and draws about 14A. At 50W that becomes about 3.2V and about 16A, and at 60W about 3.5V and about 17A. Those are substantial currents for a small battery, which is why the battery section below matters as much as the coil itself.

Compatibility is the single most important check before buying. OXVA has released several generations of hardware, and not every device or tank uses the same coil family. Unicoil heads are designed for specific OXVA hardware, and a coil that does not match the thread, base and airflow design of your tank will not seat or seal properly. Look at the markings on your existing coil, check your device's manual or box, and compare it with the compatibility details on this product page. If you are unsure, send us the model name of your device and we will tell you whether this pack fits before you buy.

On e-liquid capacity: the coil does not set the capacity, the tank or pod does. In the UK, refillable tanks and pods sold to consumers are limited to 2ml, and e-liquid bottles to 10ml for nicotine liquid. That cap sits alongside the 20mg/ml nicotine limit that applies to all UK-sold nicotine e-liquid. A thirsty 0.2Ω coil will empty a 2ml tank quickly, so expect to refill more often than you would with a high-resistance MTL coil.

Performance and vapour delivery

The defining feature of a 0.2Ω coil is how much e-liquid it can vaporise in a single draw. A larger heating surface at a low resistance heats quickly and produces a large cloud with each inhale. If your previous coil was a 0.6Ω or 0.8Ω head, the step up to 0.2Ω is obvious on the very first pull: warmer vapour, denser vapour, and a lot more of it.

Here is how that tends to show up in daily use:

  • Fast ramp-up. A low-resistance coil reaches vaping temperature almost immediately, so there is little delay between pressing the button or drawing and getting vapour.
  • Dense vapour. With the airflow open, the cloud is thick and the inhale is smooth rather than tight.
  • Warm to hot vapour at higher settings. Push the wattage towards the top of the recommended range and the vapour gets noticeably hotter. Most people settle a few watts below the maximum.
  • High liquid consumption. More vapour means more e-liquid used. As a ballpark, a regular DTL vaper on a 0.2Ω coil at around 50W can reasonably expect to get through a few millilitres of liquid in a day, noticeably more than at lower power. Your own figure will vary with how much you vape.

Wicking is the limiting factor. The cotton can only deliver liquid to the heating surface at a certain rate, so if you chain-vape or take very long draws, the wick can fall behind and you will taste a dry, slightly scorched note. The fix is simple: take shorter draws of two to four seconds, give a few seconds between pulls, and keep the tank above the half-way mark. Chain-vaping a sub-ohm coil is the quickest way to shorten its life.

The airflow setting on your tank has a large effect on how the coil behaves. A wide-open airflow cools the coil, gives the most vapour and keeps the draw airy. A partly closed airflow concentrates flavour and warms the vapour but can make the coil run hotter and wear faster. If you are used to a tighter draw, close the airflow a little at first and open it gradually until the draw feels comfortable.

It is also worth being realistic. A 0.2Ω coil is not subtle and it is not frugal. You will use more liquid, more battery and more coils than you would on a higher-resistance setup. In exchange you get a bigger, warmer, more satisfying lung hit. That is the trade-off, and it is the reason this coil is popular with vapers who switched from a mouth-to-lung setup and found it too restrictive.

Flavour profile

A coil does not have a flavour of its own. The taste you get comes from the e-liquid, and the coil's job is to heat that liquid evenly and cleanly without adding anything of its own. What the coil does influence is how the flavour is presented: temperature, intensity and consistency. On that basis, the OXVA Unicoil 0.2Ω leans towards a warm, full, rounded presentation.

Here is what to expect from different liquid types:

  • Fruit and ice blends. The larger heating surface and generous vapour volume give fruit liquids a layered, juicy character. Menthol and ice notes come through clearly, but at higher wattage the cooling can feel a little muted because the vapour itself is warm.
  • Dessert, custard and bakery liquids. These rich, sweet profiles are where warmer vapour tends to shine. The extra heat helps carry the creamy and caramelised notes. Be aware that sweet liquids leave more residue on the coil, which shortens its life.
  • Tobacco and nutty blends. Subtle profiles can come across a little heavy at the top end of the power range. Dropping the wattage a few watts often brings out finer detail.
  • Simple single-note fruits and sodas. These work well on a 0.2Ω coil because there is plenty of vapour to carry the single dominant flavour.

Almost every new coil goes through a short settling-in period. For the first few draws you may notice a slightly dull or papery taste from the fresh cotton. This disappears once the wick has been properly saturated and the coil has had a handful of draws. Priming correctly (see the how-to section below) shortens this period considerably.

Flavour will change gradually as the coil ages. In the first days, the taste is at its sharpest. After a week or two of regular use, residue from the sweeteners in your liquid builds up on the heating surface, and flavour begins to flatten. When the taste is muted even after a clean tank and a fresh fill of liquid, the coil has reached the end of its working life. Swapping it out brings the flavour back immediately.

One practical tip: if you switch between very different flavours, such as a strong menthol and a creamy dessert, the cotton can hold on to traces of the previous liquid. Many vapers dedicate one coil to each flavour family for that reason, and a five-pack makes that approach affordable.

Design and build quality

Pre-built coil heads are small, precision-made parts, and the quality you notice is mostly in the consistency between one coil and the next. A coil pack is only useful if the fifth coil performs like the first. With a five-pack from an established brand like OXVA, the aim is exactly that: identical resistance, identical wicking, identical seal.

Like other pre-built heads in this category, the Unicoil is a self-contained unit made up of these parts:

  • An outer housing, usually metal, that holds everything together and locates the coil in the tank base
  • A sealing ring, usually silicone, which prevents e-liquid from leaking past the coil into the airflow or the base
  • Wicking holes, the small openings in the housing that let e-liquid reach the cotton
  • The heating element and cotton core, which is where the work gets done
  • A bottom contact, usually the 510-style centre pin or equivalent, that completes the electrical circuit with the device

What to check when your pack arrives: look at each coil in good light before fitting it. The housing should be clean and undented, the silicone seal should be seated and not twisted, and the cotton visible through the top of the coil should be white or off-white and undisturbed. Gently rotate each coil between your fingers; it should feel solid, with no rattling. If any coil looks damaged, set it aside and contact us, and we will sort a replacement.

Storage matters more than most people realise. Keep spare coils in their original tray in a cool, dry place away from direct sunlight and heat. Do not let them roll loose in a bag with keys and coins, where the contacts can be scratched or the cotton compressed. A coil that has been knocked about or squashed may wick unevenly or leak when fitted.

The coils are small, so they are easy to drop and lose. Fit them over a clean surface, and avoid touching the cotton with your fingers, since skin oils can taint the wick and affect flavour. Handle the coil by the metal housing only.

As a design, the fit between the Unicoil head and the tank base is where quality shows over time. A properly seated coil produces a solid, quiet draw with no gurgling and no leaking. If you find a coil does not seat firmly, stop, remove it, and check that the seal ring has not rolled out of place, rather than forcing it.

Power, battery and charging considerations

The coil itself has no battery and does not charge, but it has a larger effect on your battery life than any other part of the setup. A 0.2Ω coil demands a lot of current, so it matters that the device powering it is up to the job.

Start with the numbers. At 50W, a 0.2Ω coil needs about 3.2V and about 16A at the coil, and because the cell in your device sits at around 3.7V nominal, the cell is supplying well in excess of 10A at that setting. Not every battery can do this safely. If your device takes removable cells, use only cells rated for a continuous discharge current comfortably above what you will draw. For a coil like this at typical settings, a high-drain cell with a continuous rating of 20A or more is the sensible choice. Never use an unmarked or rewrapped cell.

How long will a battery last? A rough calculation helps set expectations:

  • A 3000mAh cell stores roughly 11 watt-hours of energy. At 50W, a four-second draw uses about 0.056 watt-hours, so an ideal full charge covers about 200 draws. Allowing for conversion losses, plan on around 170.
  • A smaller built-in battery of around 1000mAh stores roughly 3.7 watt-hours, which at the same 50W works out at something like 55 to 65 draws per charge.
  • Drop the wattage and those figures rise. At 40W you gain about a quarter more draws from the same charge.

These are estimates, not promises. Real-world figures depend on the device, temperature, how long you hold each draw and how worn the battery is. But they show why a heavy DTL user often carries a spare cell or a power bank.

Charging advice for devices that charge through USB-C:

  • Use the cable supplied or a reputable replacement, and a standard wall adapter or computer port
  • Do not leave a vape charging unattended or overnight, and never charge it on soft furnishings
  • Stop using and stop charging any battery that is swollen, hot, dented or leaking
  • For removable cells, use a proper external charger rather than charging in the device if your device supports it
  • Never carry loose cells in a pocket with keys or coins; use a plastic case

When a battery reaches the end of its life, do not put it in household rubbish or general recycling. Take it to a battery recycling point, which you will find at most supermarkets and council recycling centres. Retailers who sell vaping products also have obligations to take back waste electrical and battery items, so ask if in doubt.

Coil technology, resistance and wicking

The inside of a coil is simple in principle and fiddly in practice. An electrical current runs through a resistive metal element. The element heats up. Cotton wrapped around or against the element soaks up e-liquid and presents it to the hot metal, where it turns to vapour. As you draw, fresh liquid wicks in from the tank through the openings in the housing to replace what was used.

Four things determine how a coil behaves:

  • Resistance. At 0.2Ω, this coil is a low-resistance design that favours power and vapour volume.
  • Heating surface. A larger surface area spreads heat across more of the wick, which gives even vaporisation, a smoother draw and less risk of hot spots. Always rely on the technical details printed on the pack for the exact construction of the Unicoil element.
  • Wicking material and density. Cotton is the norm. Packing density has to balance two needs: loose enough to let liquid through quickly, tight enough that it does not flood the airflow.
  • Wicking openings. The size and number of holes determine how fast liquid reaches the cotton. Large openings suit thicker, high-VG liquids.

Pre-built coils such as the Unicoil take the guesswork out of all of this. Building your own requires wire, cotton, tools, and an understanding of safe build resistance. A pre-built head is manufactured in controlled conditions to a consistent specification, which is why many vapers prefer the convenience.

Run the coil in power (wattage) mode unless your device manual says otherwise. Temperature control modes depend on the specific wire material in the coil, and a pre-built head will not necessarily match what the mode expects. Always stay within the wattage range printed on the pack.

Why do coils die? There are three main causes. First, residue builds up on the heating element from sweeteners and flavouring in the liquid, which dulls flavour and eventually causes a burnt taste. This is gradual and is the most common reason for replacing a coil. Second, the cotton can dry out or scorch if the tank runs low or you chain-vape. Third, the element can fail electrically, which usually shows as an error message such as a short circuit or no atomiser found. Spacing your draws, keeping the tank topped up and not over-powering the coil all slow the first two causes.

One last point: a dry burn, where you fire the coil with no liquid, is not a cleaning method and it will damage a pre-built head. Do not do it.

Nicotine strength and e-liquid guidance for a 0.2Ω coil

Nicotine strength is where many people go wrong when stepping up to a sub-ohm coil. A 0.2Ω coil produces a lot of vapour per draw, which means a lot of nicotine per draw if your liquid is strong. The general principle is simple: the more vapour a setup produces, the lower the nicotine strength should be.

The following are general guidelines for adult vapers who already use nicotine. They are not medical advice.

  • 0mg to 3mg freebase nicotine: the most common range for a 0.2Ω coil. Vapour is smooth and the throat hit is mild.
  • 3mg to 6mg freebase nicotine: suited to people stepping down from a stronger MTL setup who still want a noticeable throat hit. Many DTL vapers settle here.
  • Above 6mg freebase: usually too harsh for this much vapour at typical wattages. If you need more nicotine than this, you are probably better served by a higher-resistance coil.
  • Nicotine salts: salt nicotine liquids are designed for low-power, high-resistance devices. At 10mg or 20mg, a sub-ohm coil at 50W will deliver a very large nicotine dose per draw and is rarely a comfortable or sensible match. If you use salts, a higher-resistance coil is the better pairing.

The UK rules are straightforward. Nicotine e-liquid sold for refillable devices is capped at 20mg/ml, in bottles of no more than 10ml, with refillable tanks capped at 2ml. That 20mg cap used to be associated with single-use disposable vapes, but disposables are no longer legal to sell in Great Britain, so a refillable system with replaceable coils is now the standard route. It is also a more sustainable one, because you replace a small coil rather than throwing away a whole device.

On the e-liquid base, aim for a high-VG blend, around 70VG / 30PG, or a balanced 60/40 if you find the wick struggles with thicker juice. Very thin liquids can seep and cause leaking, while very thick liquids can starve the wick if you chain-vape. If the wick is regularly dry, you are either drawing too fast or the liquid is too thick for the openings, and switching to a slightly thinner blend usually solves it.

Finally, remember that nicotine is addictive. If you do not currently use nicotine, vaping is not recommended. If you are using vaping to stop smoking, a low nicotine strength combined with this coil is workable, but talk to your local stop smoking service or pharmacist for support tailored to you.

Who the OXVA Unicoil 0.2Ω is for

Not every coil suits every vaper, and a good buying decision starts with an honest look at your habits. Here is a plain summary.

This coil is a good fit if you:

  • Already own an OXVA device or tank that takes Unicoil heads and need replacements
  • Prefer a lung inhale with plenty of airflow and a big, smooth cloud
  • Use a low nicotine strength, typically 0mg to 6mg freebase, in a high-VG liquid
  • Enjoy fruit, dessert and sweet liquids where warm vapour carries flavour well
  • Want a stock of spares so you are never caught without a working coil

You should probably look elsewhere if you:

  • Prefer a tight, cigarette-style mouth-to-lung draw. A higher-resistance coil is a better match.
  • Use high-strength nicotine salt liquid. The nicotine delivered per draw would be too much.
  • Have a device with a small built-in battery and want a full day of use between charges. A 0.2Ω coil will drain it quickly.
  • Do not own compatible OXVA hardware. Coils are not universal, and a mismatch will not work.
  • Are not a current nicotine user. Vaping is not for non-smokers or under-18s.

It also helps to think about how you use your device across a typical day. A commuter who vapes a handful of times between stations might find a 0.2Ω coil overkill, using up a coil and a battery for puffs that a smaller, more efficient setup would serve perfectly. Someone who vapes steadily through a working day, on the other hand, will appreciate the volume and warmth, and will be glad of a five-pack.

If you are moving from disposables to a refillable device, a 0.2Ω coil is a big jump in power. Many people find a mid-range resistance, somewhere between 0.4Ω and 0.8Ω, easier to start with, and then step down to 0.2Ω if they want more vapour. There is no rule that says you must start at the low end, and starting higher is usually cheaper on liquid and battery.

For experienced vapers who know they enjoy a warm, dense DTL experience, the 0.2Ω is straightforward and predictable, and the five-pack format keeps the cost per coil reasonable.

How to fit, prime and use the coil

Fitting a pre-built coil takes a couple of minutes, and doing it carefully is the best thing you can do for flavour and lifespan. Follow these steps, and check your tank's manual for any model-specific details.

  • Step 1: Switch off. Turn the device off, or remove the tank from the battery, before you do anything else.
  • Step 2: Empty the tank. Pour out any remaining e-liquid, and let the tank dry briefly if you are changing flavours.
  • Step 3: Remove the old coil. Unscrew or pull out the used coil, depending on the design. Check that the old seal ring comes out with it.
  • Step 4: Clean the base. Wipe the tank base and the coil seat with a dry, lint-free cloth or tissue. A clean seat gives a better seal.
  • Step 5: Inspect the new coil. Check that the silicone seal is in place and the cotton is intact.
  • Step 6: Seat the coil firmly. Push or screw the new coil in until it is fully seated and flush. A loose coil causes leaks and poor contact.
  • Step 7: Prime the coil. Put a few drops of e-liquid directly onto the exposed cotton through the openings, then let it soak in. This is the most important step.
  • Step 8: Fill the tank. Fill with e-liquid to just under the maximum line, and avoid pouring liquid down the central airflow tube.
  • Step 9: Wait. Let the tank stand for five to ten minutes so the cotton fully saturates. It is tempting to skip, but impatience is the number one cause of burnt coils.
  • Step 10: Start low. Set the wattage at the low end of the printed range, take a couple of gentle draws without firing at full power, then raise the wattage gradually to your preferred setting.

Day-to-day use tips:

  • Take draws of two to four seconds and leave a few seconds between them
  • Keep the tank at least half full, since a low liquid level is a leading cause of dry hits
  • Open the airflow for more vapour and a cooler draw, close it for more flavour concentration
  • If you change flavours, change the coil rather than trying to rinse a used one
  • Keep a spare coil and a spare battery with you if you vape heavily

Cleaning a used coil is not worthwhile. Rinsing one can leave water in the cotton and damage the element. Replace it when flavour drops.

Finally, dispose of used coils responsibly. Wrap the spent coil in tissue and follow your local council's guidance for small items. Coils are not household recyclables in most areas, and they should not be put in with batteries. Used vaping hardware and batteries can be taken to household waste recycling centres or retailer take-back points.

Troubleshooting common coil problems

Most coil problems have a simple cause and a simple fix. Work through this list before deciding a coil is faulty.

  • Dry or burnt taste straight after fitting. The coil was not primed or the tank was not left to soak. Remove the tank, add a few drops of liquid to the cotton, refill, wait ten minutes and try again at a lower wattage. If a burnt taste persists on a fresh coil, the cotton has probably been scorched and the coil should be replaced.
  • Dry hits mid-tank. The liquid level is low, the draws are too long or too frequent, or the wattage is too high. Top up, draw more gently and reduce power.
  • Leaking from the base or airflow. Check the coil is seated fully and the seal is in place. Do not overfill. A very thin liquid or a worn-out seal can also be to blame. Wipe the tank and base before refitting.
  • Gurgling or spitting. Condensation or excess liquid in the airflow. Remove the tank, blow gently through the airflow to clear it, and wipe down.
  • Weak vapour or muted flavour. A residue-coated coil near the end of its life. If a fresh coil and fresh liquid do not restore the flavour, the old coil is finished.
  • Error message such as short circuit, no atomiser or check coil. Often a poor connection. Remove the coil, wipe the contact, refit, and make sure it is fully seated. If the message persists with a fresh coil, try a second coil from the pack and check the device with a different tank.
  • Hissing or crackling. Often caused by overly thick liquid, flooded cotton or over-powering. Lower the wattage and give the wick time to catch up.
  • Device fires but produces no vapour. The wick is dry, the airflow is blocked or the coil has failed. Check the liquid level and airflow, then swap the coil.

When to stop and replace: if the coil gives a burnt taste that persists after priming and refilling, if it leaks repeatedly after correct seating, or if the device will not recognise it, swap it out. Do not push on with a coil that tastes burnt, as inhaling overheated cotton is unpleasant and unwise.

When to contact us: if a coil is clearly faulty on arrival, such as a damaged housing, a missing seal or a resistance reading far from the stated value, let us know with your order number. Coils are consumable, so normal wear is not a fault, but a defect that exists from day one is something we are happy to put right. Also see the Consumer Rights Act points in the value section below.

Lifespan, value for money and how it compares

Coils are the main running cost of a refillable vape, so it is worth thinking about cost per week rather than cost per pack. How long a 0.2Ω coil lasts depends mostly on how you use it. As a general guide, a heavy user on sweet liquids at higher wattage might get one to two weeks. A lighter user on less sweet liquids at moderate wattage can sometimes stretch a coil to three weeks or a little more. If you take the middle of that range, a five-pack covers roughly two months of regular use.

Factors that shorten coil life:

  • Very sweet or dessert liquids, which leave more residue on the element
  • High wattage at the top of the recommended range
  • Chain-vaping and long draws
  • Letting the tank run low
  • Poor priming when fitting

Factors that lengthen it: moderate wattage, shorter draws, a topped-up tank and proper priming. A little care noticeably extends the time between coil changes.

On value, the main argument for a pack of five is simple: the per-coil price in a multi-pack is generally lower than buying single coils, and you hold a stock of spares. Compare the price per coil rather than the price per pack when you shop around, and be wary of unusually cheap packs from unknown sources, since counterfeit coils are a real problem in the vape market and can have inaccurate resistance and poor build quality. Buying from a UK retailer helps you avoid them.

How does it compare with alternatives? Honestly and fairly:

  • Other brands' sub-ohm coils. Brands such as Vaporesso (GTX range), Voopoo (PnP range) and Uwell make their own 0.2Ω-class coils. They are excellent for their own devices, but they are not interchangeable with OXVA hardware, so this is not a like-for-like swap. If you own OXVA hardware, you buy OXVA coils.
  • Higher-resistance OXVA coils. If you want longer battery life, less liquid use and a tighter draw, a coil of 0.6Ω to 1.0Ω in the same family will serve you better. It will give less vapour and a cooler, more restrained experience.
  • Disposable vapes. Single-use devices are no longer legal to sell in Great Britain, and in any case a refillable system with replacement coils is cheaper over time and produces far less waste.
  • Third-party or unbranded coils. They can look similar but may vary in resistance and wicking quality. We recommend genuine OXVA coils for consistent results and so that any warranty on your device remains intact.

On returns and warranty: coils are consumable, so normal wear and tear is not covered, but under the Consumer Rights Act 2015 goods must be as described and of satisfactory quality. A coil that is faulty on arrival, or the wrong item, can be returned or replaced. Check the delivery and returns page for the current process.

If you are unsure whether the 0.2Ω is right for your setup, a good compromise is to buy this pack alongside a pack of a higher-resistance coil from the same range and compare. For anyone running Unicoil-compatible OXVA hardware in DTL mode, this is a straightforward, sensibly priced way to keep going.

Most people use between 0mg and 6mg freebase nicotine in a high-VG liquid, because a 0.2Ω coil produces a lot of vapour per draw. Stronger liquids and nicotine salts usually feel harsh at this resistance. The legal maximum for UK-sold nicotine e-liquid is 20mg/ml.

How do I charge the device that runs this coil?

The coil does not charge, since it only heats your e-liquid, but your device battery does. Charge it with the supplied USB-C cable or a reputable replacement and never leave it charging unattended or overnight. A 0.2Ω coil draws a lot of current, so expect to charge more often than with a higher-resistance coil.

Can I use different flavours with the same coil?

You can, but the cotton holds on to traces of the previous liquid, so strong flavours can ghost into the next one. Many vapers dedicate a coil to each flavour family, and a five-pack makes that easy. Rinsing a used coil is not recommended.

How long does an OXVA Unicoil 0.2Ω last?

Roughly one to three weeks depending on how heavily you vape, what wattage you use and how sweet your e-liquid is. A pack of five typically covers around two months of regular use. Sweet liquids, high power and chain-vaping all shorten coil life.

Is a pack of five good value?

A multi-pack usually works out cheaper per coil than buying singles, and it means you always have a spare. Compare the price per coil rather than per pack, and buy from a UK retailer to avoid counterfeit coils with inaccurate resistance.

Who should not buy this coil?

Anyone who prefers a tight mouth-to-lung draw, uses high-strength nicotine salts, or does not own compatible OXVA hardware should look at other options. It is also not suitable for non-smokers or anyone under 18. Check your device before ordering.

Will this coil fit my device?

Unicoil heads are made for specific OXVA hardware, and not every OXVA device uses them. Check the markings on your current coil and the compatibility details on this page. If you are unsure, send us your device model and we will confirm before you buy.

Do you deliver across the UK?

Yes, we are a UK shop and deliver to UK addresses. Delivery options, costs and timescales are shown at checkout and on our delivery page. As an age-restricted product, this item is for adults aged 18 and over.

What if a coil is faulty or I receive the wrong item?

Coils are consumable, so normal wear is not a fault, but a coil that is faulty on arrival or the wrong item can be returned or replaced under your Consumer Rights Act 2015 rights. Contact us with your order number and a photo and we will put it right.

How do I dispose of used coils and batteries?

Take batteries to a battery recycling point, found at most supermarkets and council recycling centres, and never put them in household rubbish. Used coils are small and not accepted in all kerbside recycling, so wrap them and follow your local council guidance or ask a retailer about take-back.
