VooPoo Uforce Coils (Pack of 5) overview

The VooPoo Uforce Coils (Pack of 5) are replacement atomiser heads for tanks built around VooPoo's Uforce coil system. Each pack contains five screw-in heads, so you get a full set of spares rather than a single replacement. Coil heads are consumable parts. The cotton wick and the metal heating element inside gradually wear out, and swapping the head is the routine way to bring back clean flavour and consistent vapour. If you vape daily on a Uforce-compatible tank, a five-pack covers several weeks of use without another order.

This page covers a family of five variants. The differences between them are mainly resistance, the wattage range each head is built to handle, and the style of vaping each one suits. Lower-resistance heads are made for higher power, faster ramp-up and bigger vapour output. Higher-resistance heads use less power, stretch your battery further and give a tighter, more controlled draw. Before you add a pack to your basket, choose the variant that matches the way you vape and the e-liquid you already use.

VooPoo is a Shenzhen-based manufacturer best known for the Drag series of box mods, the GENE chip platform and a long run of tanks and pod systems. The Uforce coil range grew out of that tank and mod ecosystem and has been sold in the UK for several years, so replacement heads are generally easy to find. Here is what you can expect from this product at a glance.

• Contents: five coil heads in each pack, supplied sealed. No tank, battery or e-liquid is included.
• Type: replaceable screw-in atomiser heads using cotton wicking and a mesh or wire heating element, depending on the variant you pick.
• Best for: vapers already running a Uforce-compatible tank who want reliable spares at a lower cost per head than buying one at a time.
• Age restriction: sold to adults aged 18 and over only. Nicotine is addictive, so these are for existing smokers and vapers rather than anyone new to nicotine.

The coils themselves contain no nicotine. They are only the heating part of your setup, which means the experience you get depends on three things working together: the coil you choose, the power your device delivers and the e-liquid you put in the tank. The sections below walk through each of them so you can get steady results from every head in the pack.

Compatibility: which tanks take Uforce coils

Compatibility is the first thing to check with any replacement coil, and it is where most wrong orders come from. Uforce coils thread into the base of tanks that use the Uforce coil system, such as the tank supplied with the Drag 2 kit and other VooPoo products that share the same base. They are not interchangeable with VooPoo's PnP coils, with the TPP range, or with coils from other brands. A head that looks similar can still have a different thread, a different seating depth and a different juice-hole layout, and forcing the wrong one in risks leaks, poor contact or a damaged tank base.

The easiest way to confirm a match is to look at the head already in your tank. Most coil heads are etched or printed with a model code and a resistance value on the metal collar. Compare that code with the variants on this page. If your old coil is missing or unreadable, check the manual that came with the tank or kit, which normally lists every coil code the tank accepts together with its recommended wattage range.

• Check the code: match the letters and numbers on your current head to the variant you are ordering.
• Check the tank base: Uforce-series tanks have a particular base design, and you should not try to fit PnP or other threaded coils into it.
• Check your device limits: some regulated devices have a minimum resistance, often around 0.1 ohm. Make sure the variant you choose sits comfortably above it.
• Check capacity rules: tanks sold in the UK for nicotine e-liquid are limited to 2ml in the box, with larger glass or extension kits sometimes supplied for nicotine-free liquids and international editions. The coil fits either way, but your tank volume affects how often you refill and how long the coil stays saturated.

If you are still unsure after checking, take a clear photo of the base of your tank and the old coil, and send it to customer support before ordering. It takes a minute and saves a return. Remember too that coil heads are sealed, hygiene-sensitive items, so an opened pack generally cannot be sent back just because it turned out to be the wrong code for your tank. Getting the match right before you buy matters more with coils than with most accessories.

Mesh and coil technology explained

Most of what makes a modern coil head perform comes down to the heating element and the wick wrapped around or behind it. Uforce heads use cotton wicking in contact with a metal element, and the element is built either as a mesh sheet or as a wire arrangement depending on the variant. The pack text and the model code on the head identify which you have. The principle is the same across the family: e-liquid soaks into the cotton through ports on the side of the head, the element heats up when you press the fire button, and the liquid on and near the element turns to vapour.

Mesh elements have become popular because of how much surface area they offer. A mesh sheet is rolled into a cylinder, so the cotton sits against a large, flat-ish area of metal rather than a narrow strip of round wire. That tends to give faster ramp-up, more even heating across the wick and fewer cold spots, which means more of the e-liquid is vaporised properly instead of spitting or leaving a burnt edge.

• Faster ramp-up: a larger heated area reaches vaping temperature quickly, so the first puff of a draw already has flavour.
• More even vaporisation: heat is spread across the wick, which reduces the localised overheating that causes harsh hits.
• Good compatibility with thicker liquids: the wide wicking surface copes well with high-VG juices, within the limits covered later.

Materials matter too. Many mesh coils use a Kanthal-type alloy, while some use stainless steel such as SS316L. Kanthal should be used in standard wattage mode only. Stainless steel heads can be used in temperature control mode on devices that support it, which holds the element below a set temperature and reduces the chance of a dry hit. Check which material your chosen variant uses before enabling any temperature control setting, because applying a temperature curve to the wrong alloy can make the device misread the coil.

Mesh is not magic. It does not remove the need for patience when priming, and heavily sweetened liquids can still build residue on the element over time. What it does offer is a consistent, repeatable vape across the life of the head, which is why it is now the default choice for most sub-ohm tanks.

Performance and vapour delivery

Performance with Uforce coils depends heavily on which variant you pick, because resistance determines how much power the head can take and how much vapour it produces. As a general rule, a lower-resistance head run toward the upper end of its wattage window produces more vapour and a warmer hit, while a higher-resistance head run at lower power produces a cooler, tighter draw with less liquid consumption. The labelled wattage range on the pack is a design limit, not a target. Most people find their best results somewhere in the lower to middle part of that range.

Ramp-up on a mesh head is quick, usually within a fraction of a second after pressing fire at sensible power. Vapour density is the main reason people choose the lower-resistance variants, and these are aimed squarely at direct-to-lung vaping, where you inhale straight into the lungs through a wide airflow slot. Higher-resistance variants suit restricted direct-to-lung and, with the airflow closed down, some mouth-to-lung styles, though they will not feel identical to a dedicated mouth-to-lung pod coil.

• Lower-resistance heads: higher wattage, thicker clouds, warmer vapour, faster e-liquid and battery drain.
• Mid-range heads: a balance of flavour, vapour and efficiency that suits most people moving from a pod system to a tank.
• Higher-resistance heads: lower wattage, longer battery life, less liquid used per puff and a slightly more restrained throat hit.

Liquid consumption is something new tank users often underestimate. A sub-ohm style head running at 50 to 60 watts can use several millilitres of e-liquid in a day of regular vaping, which is quite different from a small prefilled pod. That affects running costs, and it also affects how often you must top up to keep the cotton saturated. Never let the tank drop below roughly a quarter full, because once the liquid level falls below the juice holes, the cotton starts to dry out and burn.

Airflow adjustment on the tank itself also changes the result. Opening the airflow fully cools the vapour and gives bigger clouds but dilutes flavour slightly. Closing it down gives a warmer, more concentrated hit. It is worth experimenting for a day with a fresh head before settling on your preferred combination of wattage and airflow, because small changes make a noticeable difference.

Flavour profile and how the coil shapes it

The coil does not add a flavour of its own, but it has a large effect on how clearly the flavour in your e-liquid comes across. Mesh heads in particular are valued for clarity: because the wick is heated evenly, the individual notes in a recipe tend to come through more distinctly instead of blurring into a generic sweet vapour. Fruit blends, menthol and ice flavours, tobacco and dessert recipes all benefit, though each behaves a little differently as the head ages.

A new head goes through a short settling period. During the first day or two, the cotton continues to fully wet and the element finishes bedding in, and flavour usually builds to its peak. Over the following days it holds steady. As the head approaches the end of its life, the first change most people notice is a slight flattening of flavour, followed by a faint toasted note. That is your cue to swap, long before the taste turns properly burnt.

• Fruit and ice flavours: these show off the clean ramp-up of mesh, with bright top notes and a defined cooling finish.
• Dessert and bakery flavours: sweeteners in these recipes caramelise on the element, so they tend to shorten coil life. Expect to change heads a little sooner.
• Tobacco and nut flavours: these cope well with the warmer end of the wattage range, which brings out depth.
• Menthol and mint: these usually stay crisp with the airflow fairly open.

Power setting changes flavour more than most people expect. Staying near the lower end of the wattage range keeps vapour cooler and puts the emphasis on flavour. Pushing toward the top increases vapour volume but tends to mute delicate notes and shorten the life of the head. If you find a flavour tasting thin, try reducing wattage by a few watts before assuming the coil is at fault.

If you rotate between very different recipes, such as a strong menthol and a creamy dessert, keep in mind that cotton holds residue. A coil that has been used with menthol can leave a ghost of it in the next flavour. Having five heads in a pack makes it practical to dedicate one head to each family of flavours instead of forcing one coil to do everything.

Design and build quality

A Uforce coil head is a small, self-contained part, and the build details are worth knowing because they decide how well it seals, conducts and wicks. At the base there is a metal contact that makes the electrical connection with the tank, separated by an insulating ring from the threaded collar. Above that sits the heating element, held in place within a metal shell and wrapped in cotton. Along the side of the shell are the wicking ports that let e-liquid in. The head threads into the tank base and seals with a rubber ring, so the whole assembly can be removed and replaced without tools.

When you open a pack, it is worth giving each head a quick visual check. Genuine, undamaged heads should look clean and uniform.

• Cotton: should be neatly tucked and evenly distributed, with no loose fibres poking out of the juice ports and no flattened or crushed areas.
• Shell and threads: should be clean, round and free of burrs, with no visible dents that would stop the head seating squarely.
• Sealing ring: should be intact and sit flat. A pinched or missing ring is a common cause of leaks.
• Markings: the model code and resistance value should be legible on the collar and match the pack.

Counterfeit coils exist for popular ranges, and they are one of the main reasons for inconsistent resistance, poor wicking and early failures. Buying from a reputable UK retailer, checking the packaging for clear and crisp printing, and being cautious about unusually cheap listings all reduce the risk. If a head arrives visibly damaged or does not read the resistance printed on it, contact support rather than vaping on it.

The physical design also affects how easy the part is to handle. The heads are small, so fit them with clean, dry fingers over a flat surface in case anything drops. Do not squeeze the shell or pinch the cotton while installing, and do not twist the head hard once it is seated. Snug is enough. Overtightening can deform the sealing ring and cause exactly the leaking you are trying to avoid. With sensible handling, the build quality is consistent across the pack, and the real variable becomes how you vape and which liquid you use.

Power, battery and charging with Uforce coils

The coil heads have no battery of their own, so charging concerns the device you pair them with. Even so, the coil and battery are linked more closely than many beginners realise, because the resistance of the head sets how hard your battery has to work. Power in watts equals voltage squared divided by resistance, and the current drawn from the battery equals the square root of power divided by resistance. In practice that means a low-resistance head at high wattage asks a lot of the cell.

• A 0.2 ohm head at 60 watts draws roughly 17 amps from the battery.
• A 0.4 ohm head at 30 watts draws roughly 9 amps.
• A higher-resistance head at 15 watts draws far less, which is why it is easy on batteries and gives longer runtime.

These figures show why you should match the coil to the device. If your mod uses removable 18650 or 21700 cells, make sure the cells are quality cells from a known brand and that their continuous discharge rating is comfortably above the current your coil will pull. Never rely on a rating you cannot verify, and avoid unbranded cells sold as high capacity at a low price. If your device uses an internal battery, check the maximum output in the manual and stay inside it.

Charging habits make a real difference to safety and lifespan. Use the cable supplied with the device or a good quality USB-C cable, and a reputable plug. Do not charge on soft furnishings, and do not leave a device charging unattended overnight. For removable cells, an external charger lets you monitor the process and is kinder to the cells over time. Keep spare cells in a plastic case, never loose in a pocket with keys or coins.

Power settings also influence battery life. Running the same coil at the top of its range rather than the middle can cut runtime considerably while adding relatively little to the experience. Spent or damaged batteries should never go in household bins. In the UK, batteries can be taken to supermarket collection points and household waste recycling centres, which accept them for safe processing.

E-liquid and nicotine strength guidance

Choosing the right e-liquid is as important as choosing the right coil, and the two have to suit each other. In the UK, nicotine e-liquid is capped at 20mg/ml, and nicotine bottles are limited to 10ml. The same 20mg cap applies across the board, to refill liquids and previously to disposables, which are now banned from sale in the UK as of June 2025. Reusable systems such as a Uforce tank with replaceable coils are the normal route for adults who vape, and they allow you to pick your strength precisely.

Nicotine strength should reflect the resistance of your coil. High-power, low-resistance vaping delivers a lot of vapour with each puff, which means a lot of nicotine if the strength is high. Because of that, low-resistance heads are normally paired with low-strength liquid. Higher-resistance heads, with a tighter draw and less vapour, suit stronger liquids. The ranges below are starting points, not medical advice, and you should adjust to your own experience.

• Low-resistance heads, 50 to 60 watts and above: nicotine-free shortfills with added nicotine shots to reach about 3 to 6mg, or low-strength liquid in the 3 to 6mg range. Choose a 70VG/30PG blend or similar.
• Mid-resistance heads, 25 to 40 watts: about 6 to 12mg, often in a 60VG/40PG or 50/50 blend.
• Higher-resistance heads, lower wattage: about 10 to 20mg nicotine salt in a 50/50 blend, which gives a smoother throat hit at higher strengths.

Nicotine salt liquids are smoother at high strength but are generally not suited to very high wattage, where they become harsh and deliver too much nicotine. Freebase nicotine suits lower strengths and higher power. If you are moving from cigarettes, it is common to start higher and step down over time as cravings settle. If you are moving from a pod system, remember that a tank gives a much bigger puff, so you will usually need a lower nicotine strength than your pod liquid.

Finally, think about viscosity. Mesh handles thick liquids well, but very high-VG liquids, above about 80 percent VG, can wick slowly at low wattage and cause dry hits if you do not prime properly. Stay within 50 to 70 percent VG for most variants unless the pack says otherwise.

Who these coils are for

Uforce coils are aimed at adults who already use a compatible tank and want straightforward, reliable replacements. Because the family covers a spread of resistances, there is a sensible choice for several types of vaper, but there are also people for whom a different product would suit better.

These coils make good sense for:

• Existing Uforce tank owners: if you already have the tank, a five-pack is the practical way to keep it running, and buying in multiples brings down the cost of each head.
• Ex-smokers using a reusable tank: with disposables now off the UK market, a refillable tank and a spare supply of coils is a cost-effective route to continue vaping instead of smoking.
• Flavour-focused vapers: mesh heads are valued for flavour definition, which suits people who care about the taste of their e-liquid more than sheer cloud size.
• People who rotate flavours: five heads let you dedicate one to each style of e-liquid and reduce flavour carryover.
• Anyone who wants predictable maintenance: swapping a head every week or two is simple and does not need any building skills.

They are less suitable if:

• You use a PnP, TPP or other coil system. These heads will not fit, and you should look for the correct coil for your own tank.
• You prefer the simplicity of a prefilled pod. A tank and coil require refilling, priming and a little routine maintenance.
• You have never smoked or vaped. Nicotine is addictive and vaping is not recommended for non-smokers, and these products are for adults only.
• You are buying for someone under 18. The sale of vaping products to under-18s is illegal in the UK.

If you are undecided between variants, think about your habits. Frequent, large inhales point toward lower-resistance heads and low-strength liquid. Frequent, small, discreet puffs suggest a higher-resistance head with a stronger nicotine salt. Casual or occasional use points toward the middle of the range, where one head tends to last a bit longer because of the lower power draw.

How to fit, prime and use your coil

Fitting a coil takes a couple of minutes, but the priming step decides whether the first few puffs taste good or burn. Rushing it is the most common reason a brand new head fails early.

• Step one: switch the device off or lock it, then unscrew the tank and remove the old head. Empty any remaining liquid into the tank before removing it, and wipe the base and threads with a dry tissue.
• Step two: take a fresh head from the pack and check the sealing ring and cotton as described earlier.
• Step three: add a few drops of e-liquid directly onto the cotton through each wicking port on the side. Do not flood the central chimney.
• Step four: screw the head into the tank base until snug, then fill the tank to just below the maximum line, taking care not to overfill the airflow channel.
• Step five: wait at least five to ten minutes so the cotton saturates fully. Thicker liquid needs closer to ten.
• Step six: set the device to the low end of the coil's wattage range, take two or three gentle puffs without firing for long, then move to your usual power.

Never fire a dry coil. If the cotton is not wet you will scorch it in a second, and the burnt taste can stay for the rest of its life. Do not chain vape on a brand new head until it has fully bedded in, as the cotton needs time to keep up.

For everyday use, keep the tank above about a quarter full, refill before it gets low and avoid draining the tank to the last drop. Take shorter draws instead of very long pulls, especially at high wattage, to give the wick time to refill between puffs. If you change flavour, clean the tank thoroughly with warm water, dry it fully, and fit a fresh head.

When the time comes to dispose of a spent head, do not simply bin it with loose batteries or electronics. Many UK household waste recycling centres and vape retailers will take used vape components, and the Recycle Your Electricals scheme lists drop-off points near you. Used coils contain residue of nicotine liquid, so keep them away from children and pets until they are disposed of.

Troubleshooting common coil problems

Most coil issues have a simple cause and a quick fix. Work through the likely causes before assuming the head is faulty, because poor priming, low liquid or wrong power cause far more problems than a defective part.

• Burnt or dry taste on a new coil: usually under-priming. Remove the tank, add a few more drops to the cotton, wait ten minutes and restart at a lower wattage. If the taste persists after a full tank, the head may have been scorched and should be replaced.
• Gurgling or spitting: too much liquid in the chamber or airflow. Blow gently through the drip tip to clear it, and avoid overfilling next time. Check that the tank is assembled with the seals correctly seated.
• Leaking from the airflow slots: usually a poorly seated head, a damaged sealing ring or overfilling. Reseat the coil, check the ring and wipe the base dry.
• Weak or flat flavour: a fading head, a power setting that is too high, or residue from a previous flavour. Reduce wattage, clean the tank and fit a fresh head if the issue continues.
• Device shows no atomiser or coil error: the head is not making contact. Unscrew and refit it, clean the contact point at the bottom of the head and the tank pin, and check the resistance is within your device's range.
• Coil dies quickly: frequently caused by very sweet liquids, very high wattage, chain vaping or running the tank too low. Adjust those habits before blaming the product.
• Hissing or crackling: often a sign the cotton is not keeping up with the power. Lower the wattage or use a slightly thinner liquid.

If you have followed these steps and a brand new head still fails to work, or the resistance reading is clearly wrong, it may be faulty. Keep the packaging, note the batch information if printed and contact customer support with your order number and a photo. Faults are dealt with under your normal consumer rights, and spotting them early helps support resolve the issue faster.

One extra tip: many people replace the head on a fixed schedule, for example once a week, instead of waiting for the taste to go. This avoids ever tasting a burnt hit and tends to make the whole routine less stressful.

Value for money and how Uforce compares

Coils are a running cost, so value is about cost per week of good vaping rather than the price on the box. A pack of five reduces the price of each head compared with buying a single replacement, and with sensible use each head typically lasts somewhere between one and two weeks, depending on liquid sweetness, wattage and how often you vape. That means one pack can cover roughly five to ten weeks. Heavy daily vapers will sit at the shorter end, light users at the longer end.

Habits that stretch the life of a head include staying in the lower to middle part of the wattage range, keeping the tank topped up, priming properly, and choosing liquids that are not extremely sweet. Habits that shorten it include chain vaping, high power and letting the tank run low.

It is fair to compare Uforce with other options, bearing in mind that coil systems are not interchangeable, so the real decision is which platform to commit to.

• Compared with VooPoo PnP coils: PnP is the newer system and is found on most of VooPoo's recent kits, with a wider range of variants and generally more current hardware. Uforce suits you if you already own a compatible tank, but if you are buying a fresh device, check which coil system it uses so that you are not choosing a platform with fewer new products.
• Compared with GeekVape and Vaporesso mesh heads: both brands offer well regarded mesh coils with comparable performance in the same wattage bands. The differences are small and mostly down to personal preference, so your tank decides the choice rather than the coil.
• Compared with SMOK mesh coils: similar mesh technology and price band, and SMOK has a very large range. Availability and variety are strong, though quality can vary slightly between ranges.
• Compared with closed pods such as Uwell Caliburn style systems: pods are simpler and more discreet, but the cost per millilitre of liquid is usually higher and you cannot freely choose your juice. A tank with Uforce coils gives you control of liquid, strength and power at a lower running cost for regular users.

On balance, Uforce coils are a sensible purchase if you already run the matching tank. They deliver steady performance and good flavour, they are easy to fit, and the five-pack makes upkeep inexpensive. They are not the right buy if your tank uses a different coil system, so double-check compatibility first and choose the variant that fits your power and nicotine preferences.
