Overview: what these Hayati Mini Ultra pods are

This listing covers replacement pods for the Hayati Mini Ultra pod system, supplied in two fruit flavours: Blueberry Cotton K and Raspberry Cotton K. The pods are pre-filled with nicotine salt e-liquid and have the coil built into the pod, so there is nothing to refill, nothing to prime with a dropper and nothing to measure. You take the used pod off the device, click a fresh one on and carry on. That simplicity is the whole appeal of the format, and it is why a pod refill like this sits between a throwaway-style experience and a full refillable kit.

It is worth being clear about what this is not. These are pods only. The listing does not include the battery device, and the pods are intended for the Hayati Mini Ultra hardware. Do not assume they will fit another pod system because the shape looks similar; connector layouts and contact positions differ between brands, and sometimes between generations from the same brand. If you are unsure, check the compatibility information on your existing pack or message us before ordering.

Hayati is a name most UK vapers know from the disposable era. The Mini Ultra format belongs to the move toward rechargeable hardware with swappable pods that followed the ban on single-use vapes in Great Britain on 1 June 2025 (Northern Ireland follows separate arrangements). A device you keep and pods you replace generate far less waste than a bar you throw away after a few days, and used pods can go to a recycling point, which we cover in the final section of this page.

The manufacturer rates the pods at around 1,500 puffs. We treat that as a headline rating rather than a guarantee, and the performance section explains why. What you can rely on is the format itself: closed pods, a nicotine salt formulation, a mesh-style coil and a compact device that is charged by cable rather than thrown away. Each of those points has its own section below, so you can jump straight to the part that matters to you.

Everything on this page is written for adult smokers and existing vapers in the UK. If you do not currently smoke or vape, nicotine products are not for you, and you must be 18 or over to buy from us.

Flavour profile: Blueberry Cotton K and Raspberry Cotton K

Both flavours on this listing sit in the fruit category, and both lean sweet rather than sharp. We have kept the 'Cotton K' wording exactly as the brand labels it so that you can match it against the pack. Taste is subjective, and the descriptions below are our reading of how this style of flavour is normally built, not a laboratory analysis. Batches also vary slightly, so two pods of the same flavour will not always taste identical.

Blueberry Cotton K. Expect a rounded, jammy blueberry on the inhale, closer to ripe or cooked berry than to the slightly sour taste of a fresh punnet. The 'cotton' half of the name points to a soft, sugary finish on the exhale, the kind of light candied sweetness that hangs around for a second after you breathe out. Blueberry is a gentle flavour by nature, so it tends to be the easier of the two to vape through a long day. If you find sharp fruit flavours harsh on the throat, this is the pod to start with.

Raspberry Cotton K. Raspberry is naturally brighter and tarter than blueberry, and this pod should follow that pattern. You are likely to notice a livelier, slightly acidic edge on the inhale, followed by the same soft sweetness on the way out. It suits anyone who finds blueberry a little heavy or syrupy. Raspberry notes are also more volatile than blueberry notes, which means some people feel the flavour fade sooner on long sessions, a point we return to in the troubleshooting section.

The names do not mention ice, menthol or cooling agents, so expect little or no cooling effect from either pod. If cooling matters to you, read the pack before you vape; where a cooling variant exists it is normally labelled as such.

For context, these are the flavour families you will most often see across fruit-led Hayati ranges and similar pod systems:

• Blueberry (this listing)
• Raspberry (this listing)
• Blue raspberry
• Watermelon
• Strawberry ice cream
• Mango
• Peach
• Cherry cola
• Mint

Availability varies by range and by stock, so treat that list as a guide to the brand's general direction rather than a promise that every one exists for the Mini Ultra pod. Browse our other Hayati listings for what is currently available.

Because these two flavours are close cousins, a berry base with a soft sugary finish, swapping between them is easy. Many vapers keep one of each and alternate to avoid flavour fatigue, sometimes called vaper's tongue. A practical tip is to finish one pod fully before switching, and to sip some water between pods if you notice the taste dulling, since a dry mouth makes fruit flavours seem weaker than they are.

Performance and puff delivery

The pods are rated at around 1,500 puffs. Puff ratings are produced by manufacturers under standardised machine-draw conditions, usually short, evenly spaced draws with a rest between them. Real people vary a great deal. Long, slow draws use more e-liquid per puff and give you fewer puffs overall; short, light sips give you more. So the rating is better read as an upper bound under ideal conditions, not a number to budget around.

There is a second reason to be cautious. Under UK rules, a replaceable pod can hold no more than 2ml of e-liquid, and nicotine strength is capped at 20mg/ml. At the maximum, a single 2ml pod therefore holds 40mg of nicotine in total. If the pod in your hand is at or near that capacity, a 1,500-puff rating implies a very small amount of liquid per puff, which is hard to reach in daily use. If your pack contains more than one pod, the rating may be quoted per pod or across the whole pack, so check the packaging for the exact wording.

The draw on a pod system of this type is typically a mouth-to-lung style with moderate resistance, closer to the feel of a cigarette than to a loose, airy sub-ohm draw. Vapour production is moderate rather than cloud-heavy, which suits discreet use and keeps liquid consumption lower. With a nicotine salt formulation the hit is smoother than traditional freebase nicotine at the same strength, so 20mg/ml feels much gentler in the throat than it would in a freebase liquid.

Several things change how many puffs you actually get:

• Draw length. Three-second draws use roughly twice the liquid of one-and-a-half-second draws.
• Frequency. Chain vaping heats the coil repeatedly without rest, which burns through liquid and can dull flavour.
• Temperature. Cold weather thickens e-liquid slightly and can make the first few puffs feel muted.
• Battery level. A very low battery can reduce output and make vapour feel thinner.
• Liquid level. As the pod empties, the wick has less to draw from, and the last stretch can feel warmer and less flavourful.

For a realistic picture, many vapers replacing a pack-a-day habit find that a pod of this size lasts somewhere around one to three days, while lighter or social users stretch it to a week or more. Those are broad ranges based on typical pod-system use, not measurements of this specific pod. The most reliable benchmark is your own: note the day you fit a pod and the day it runs out, and use that as your personal figure for planning how many to keep in stock.

Flavour should stay steady for most of the pod's life. The one thing to watch is the final 10 to 15 per cent, when the liquid level drops and the coil has less to work with. A burnt or dry taste at that stage is the pod telling you it is finished, not a fault.

Design and build quality

The Hayati Mini Ultra is a compact pod device, small enough to carry in a jeans pocket or the corner of a bag without feeling bulky. The pods are closed units: a sealed reservoir, a built-in coil and a moulded mouthpiece in a single piece. They seat into the top of the device with a firm click, and the connection should feel snug with no wobble. Pods in this class are typically made from a clear or tinted plastic shell, which lets you see the liquid level at a glance, though the exact window design varies between versions.

The mouthpiece is the part your lips touch, so shape matters. Pod mouthpieces of this type are usually slightly flattened or rounded, with a moderate opening that suits a mouth-to-lung draw. Seals around the fill point are the main protection against leaks, and these are factory-set. You should never need to open the pod, and doing so voids any claim you might have if something goes wrong.

On the device side, compact pod batteries are normally finished in coated plastic or an aluminium alloy. Either can pick up fingerprints and light scratches in a pocket, so a separate pocket from keys and coins is sensible. These are lightweight devices built for everyday carrying, not rugged hardware designed to survive repeated drops onto pavement. Treat the device like a phone: careful, not precious.

When your order arrives, a quick check takes thirty seconds and saves trouble later:

• Look at the pod seal and shell for cracks, loose joints or damp patches.
• Check there is no liquid on the metal contacts at the base of the pod; if there is, wipe it with a dry tissue before fitting.
• Seat the pod and confirm it sits flush with the device body with no gap.
• Give the device a gentle shake near your ear; a rattle can mean a loose component and is worth reporting to us.
• Wipe the mouthpiece with a clean dry cloth before first use.

A word on leaks. Closed pods rarely leak under normal conditions, but air pressure changes on flights, hot cars and long periods stored upside down can push a small amount of liquid toward the mouthpiece or contacts. Carry the device upright where you can, and remove the pod and wipe the contacts if you notice a sticky film. That film is the most common cause of a pod that suddenly stops firing.

Overall, build quality here should be judged for what it is: a practical, affordable pocket pod system. It is not a premium metal-cased device, and nobody should expect it to be, but the closed-pod design keeps the moving parts to a minimum, which is part of why the format is dependable for most users.

Battery and charging

Battery capacity is where it helps to reason from the format rather than guess. Compact pod devices of this size normally carry a lithium-ion cell in the region of 400 to 600mAh. We do not state an exact figure here because it depends on the revision of the device you own, so check the pack or the device itself. As a rough guide, a 500mAh cell at a nominal 3.7 volts stores about 1.85 watt-hours. A pod system working at around 7 to 10 watts uses roughly 20 to 30 joules per three-second puff, which works out to a few hundred puffs per full charge. That is arithmetic, not a specification, but it makes one thing clear: you will charge the device several times during the life of a single pod.

Charging is done by cable, and most devices in this class use USB-C, although you should confirm the port on your own hardware. Use a standard phone-style charger or a USB port on a computer. Some practical points:

• Charge time. Small cells of this size usually take somewhere around 30 to 60 minutes from low to full on a typical 5 volt charger.
• Indicator light. Most devices show a charging light that changes colour or switches off when full. Check your pack for the exact meaning.
• Pass-through use. Avoid vaping while charging unless the manual says it is supported. It stresses the cell and the connector.
• Unattended charging. Do not leave any lithium device charging overnight on a bed, sofa or pile of papers. Charge on a hard, clear surface and unplug when full.
• Damaged cables. A frayed or bent cable is a reason to replace the cable, not to keep going.

Battery life degrades gradually. After a few hundred full charge cycles most lithium cells hold noticeably less than they did when new, and the device will need charging more often. That is normal for every rechargeable product from phones to vapes. If your device suddenly drops from lasting a day to lasting a few hours, or gets unusually warm on charge, stop using it and contact us rather than pushing on.

One further tip: if the device refuses to fire, the cause is often a low battery rather than a faulty pod. Plug it in for ten minutes before assuming anything is wrong. And if you are going away, a short USB-C cable in the bag costs far less than a replacement device.

Coil and mesh technology

The coil is the heating element that turns e-liquid into vapour, and it is built into the pod. This is what makes closed pods convenient: every new pod arrives with a fresh coil, so you never have to wonder when to replace one, and you never have to build, wick or prime anything yourself. The Mini Ultra pods are designed around a mesh-style coil, which is now the standard approach in this class of product.

It helps to understand the difference between a mesh coil and the older round-wire coils. A traditional wire coil is a spiral of resistance wire wrapped around a cotton wick. Heat concentrates along the wire, which makes the contact area small and can lead to hot spots. A mesh coil is a thin, flat or cylindrical sheet of perforated metal in contact with the wicking material across a much larger surface area. That brings a few practical benefits:

• Faster heat-up. The coil reaches working temperature quickly, so the first puff of a draw tastes like the tenth.
• More even vaporisation. Heat spreads across the mesh, which reduces the chance of one point scorching while the rest stays cool.
• Fuller flavour. More surface area means more of the e-liquid is vaporised at a steadier temperature, so fruit flavours like blueberry and raspberry hold their character.
• Longer coil life. Even heating tends to spread wear more evenly across the element.

Mesh is not magic, though, and it is worth being fair about the limits. Sweet e-liquids, and fruit flavours with sugary finishes in particular, leave residue on any coil over time. This is caramelisation, and it is the main reason a coil gradually loses flavour in the second half of a pod's life. Mesh slows that process but does not stop it. Likewise, a mesh coil still needs liquid to work: if you chain vape and the wick cannot keep up, you will get a dry, burnt taste regardless of coil type.

A new pod needs a short settling period. The wicking material has to soak up liquid from the reservoir, and firing the coil before it has done so is the quickest way to ruin a pod. Fit the pod, then wait around five to ten minutes before the first puff. In the meantime, a couple of gentle draws without firing, if the device is activated by draw, can help pull liquid toward the coil. We cover the full sequence in the how-to section.

Because the coil cannot be replaced separately, its life is also the pod's life. When flavour drops away and the draw feels warm, that is the end of the pod, and fitting a new one is the fix.

Nicotine strength guidance and UK rules

Nicotine strength is the single most important choice for a smoker moving to vaping, so it deserves care. In the UK, nicotine-containing e-liquid is capped at 20mg/ml (2 per cent), and replaceable pods and tanks are capped at 2ml. Those limits come from the Tobacco and Related Products Regulations 2016 and apply to every nicotine pod sold here, including the pre-filled devices that used to be sold as disposables. Pods are usually sold in 20mg/ml, and some ranges also offer lower strengths. Always read the variant name and the pack, because the strength on the pack is the one that applies to you.

Here is a straightforward way to think about choosing:

• 20mg/ml. Suited to people who smoke around ten cigarettes a day or more, or who find that lower strengths leave them reaching for a cigarette. Nicotine salt formulations make this strength smoother than it sounds, which is why it is the common starting point for heavier smokers.
• 10 to 12mg/ml. A sensible middle step for lighter smokers, those cutting down, or anyone who finds 20mg too strong.
• 3 to 6mg/ml. For people who are winding down or who vape only occasionally.
• 0mg. Nicotine-free, for those who miss the hand-to-mouth habit but no longer want the nicotine.

Signs you have picked the wrong strength are fairly easy to read. If you feel dizzy, nauseous, jittery or get a hot, harsh throat hit, the strength is probably too high, or you are vaping too often. If you are still craving cigarettes after a few days of regular use, or you are vaping constantly to feel satisfied, the strength may be too low. Move one step at a time and give each change a few days.

It is also worth knowing how nicotine salt works, because it surprises people. Salts use an added acid to lower the pH of the liquid, which makes the nicotine easier on the throat and lets the body absorb it more quickly than freebase nicotine at the same strength. The effect is that a nicotine salt at 20mg/ml feels smoother and can feel stronger in terms of satisfaction than freebase at 20mg/ml would. If you are coming from a freebase liquid at a lower strength, start by being careful, not bold.

Nicotine is addictive. These pods are intended for adult smokers who want an alternative to cigarettes, and they are not suitable for people who have never smoked, for anyone under 18, or for people who are pregnant or breastfeeding without medical advice. Each pack carries the UK-required health warning, and you should read it.

Who it is for, and who should skip it

Matching a product to the right person is more useful than a long list of features, so here is a direct answer.

These pods are a good fit if you:

• Already own a Hayati Mini Ultra device and want straightforward refills with no fuss.
• Are an adult smoker moving from cigarettes and want something simple, with no bottles, no coils to change and no settings to learn.
• Prefer fruit flavours with a soft, sweet finish and do not need menthol or heavy cooling.
• Want a pocketable, discreet device that does not produce large clouds.
• Like the idea of keeping hardware and replacing only the consumable part, which is more sustainable than a throwaway device.
• Want to alternate between two related flavours to avoid flavour fatigue.

Consider skipping them, or looking elsewhere, if you:

• Do not own the compatible device. These are pods only. Without the Mini Ultra hardware there is nothing to put them in.
• Have never smoked or vaped. Nicotine is addictive, and there is no benefit in starting.
• Are under 18. It is illegal to sell nicotine products to you, and we will not.
• Want huge clouds or a loose, airy draw. A mouth-to-lung pod system is designed for a tighter draw and modest vapour.
• Want the lowest running cost. Closed pods are convenient but, for heavy daily users, a refillable kit with 10ml bottles of e-liquid is cheaper per millilitre over time.
• Dislike sweet flavours. Both of these lean sweet. If you want tobacco, mint or something dry, pick a different flavour.
• Want a nicotine-free option. Check the variant carefully; this listing is for nicotine pods unless a 0mg option is shown.
• Need medical advice. If you have a heart condition, are pregnant or take medication that interacts with nicotine, speak to your GP or pharmacist first.

A final word for people who are still smoking. Switching completely is what delivers the benefit. Vaping alongside smoking, rather than instead of it, keeps most of the harm in place. If your aim is to quit nicotine altogether, free local stop-smoking services in the UK can pair a vape with practical support, and they are worth asking about.

How to fit, activate and use

Getting started takes about a minute, plus a short settling time. The steps are the same for both flavours.

• Step 1: Charge the device. Make sure the battery has some charge before you begin. A flat battery looks exactly like a faulty pod.
• Step 2: Inspect the new pod. Check the seal, shell and contacts as described in the design section. Remove any protective cap, film or plug from the mouthpiece or base as shown on the pack.
• Step 3: Remove the old pod. Pull it straight out, without twisting, and set it aside for recycling. Wipe the device connectors with a dry cloth if there is residue.
• Step 4: Fit the new pod. Line it up with the opening and push until it clicks. It should sit flush with no gap.
• Step 5: Wait. Leave the device for five to ten minutes so the wick can saturate. This is the step most people skip, and it is the one that matters most for avoiding a burnt first puff.
• Step 6: Take gentle first draws. Most pod devices of this type are draw-activated, so there is no button to press. Start with a couple of short, gentle draws, then settle into your normal rhythm.

A few habits will improve both flavour and pod life:

• Take draws of around two to three seconds, not long hauls. Shorter draws give the wick time to refill.
• Pause for a few seconds between puffs, particularly with sweet fruit flavours.
• Do not blow back through the mouthpiece. It can push liquid into the airflow channel.
• Keep the device upright when carrying it where possible.
• Do not cover the airflow holes with your fingers while drawing.

Switching between the two flavours is simple: remove the pod, fit the other, and wait the same five to ten minutes. If you swap often, keep each partly used pod upright in a small container or the original packaging, so that it does not leak into your pocket. A pod that has been stored on its side for a day or two will need another minute or two to settle before it fires cleanly.

Many devices have a safety cut-off that stops firing after a set number of seconds on a single draw. That is normal, and it protects the coil. If your device cuts out on long draws, shorten them.

Troubleshooting common problems

Most problems with closed pod systems are minor and fixable in under a minute. Work through these in order before deciding the pod or device is faulty.

• The device does not fire. Charge it for ten minutes. Then reseat the pod, since a pod that is slightly out of position will not make contact. Wipe the metal contacts on both the pod and the device with a dry cloth or cotton bud.
• Burnt or harsh taste on a new pod. You probably did not wait long enough for the wick to saturate. Stop, leave the device for ten minutes, then take gentle draws. If the taste persists, the pod may be faulty and we will help.
• Flavour seems weak or has faded. Sweet flavours leave residue on the coil, and your sense of taste adapts to a flavour you vape all day. Try the other flavour, drink some water, and wait. If flavour is still dull after a break, the pod is probably near the end of its life.
• Gurgling or spitting. Condensation has gathered in the airflow channel. Remove the pod, tap the mouthpiece gently on a tissue, and refit.
• Leaking from the mouthpiece or base. Wipe off any liquid, check the pod for cracks, and refit. Keep the device upright. If the pod keeps leaking, set it aside and contact us with photos.
• Weak vapour. A low battery, a pod nearly empty, or a blocked airflow slot are the usual causes. Check each in that order.
• Hot vapour. This normally means the pod is nearly empty or you are chain vaping. Slow down, and if the heat persists, replace the pod.
• The device flashes and will not respond. Flashing indicators normally signal a short circuit, a low battery or a pod not seated correctly. Reseat the pod and check your pack for what the light pattern means.
• Device or battery gets hot. Stop using it, unplug it, let it cool and do not use it again. Contact us. A hot battery is a safety matter, not a quirk.

If you have tried these steps and the pod or device still misbehaves, get in touch with your order number and a short description or photo of the problem. Keep the pod in its original condition where you can; it helps us work out whether this is a batch issue, a damaged item or a usage issue.

There is one important caveat. A pod that has been vaped heavily and has reached the end of its liquid is not faulty when it burns. Do not keep firing an empty pod. It tastes unpleasant, it wastes battery and it can overheat the coil.

Value for money and how it compares

Value is more than the number on the price tag, so here is a way to judge it. Prices change, and we do not repeat a figure here that could go out of date; check the current price on this page. What you can do is convert the price into a cost per day. Divide the price of a pod by the number of days it lasts you. As an illustration only, a pod costing £5 that lasts three days works out at about £1.67 a day. Compare that with a pack of 20 cigarettes, which now costs well into double figures, and the saving for someone who switches fully is clear.

It is also fair to be honest about where closed pods are not the cheapest option, so here are the main comparisons.

• Against other pre-filled pod systems such as Vuse ePod or Elfa-style pods. The convenience is similar: click in, vape, replace. Differences come down to pod price, flavour range, nicotine options and device feel. Compare cost per pod and pod capacity rather than the headline puff count, since puff ratings are quoted differently between brands.
• Against refillable pod kits such as the Oxva Xlim, Smok Novo or Uwell Caliburn families. Refillable systems are cheaper per millilitre once you buy 10ml bottles, and they offer far more flavour choice. In return you must fill pods yourself, change coils, and put up with the occasional spill. If you vape heavily every day, that saving is significant. If you want to open a box and get on with it, a closed pod is simpler.
• Against the former disposable market. Single-use vapes are no longer sold in Great Britain. A rechargeable device with replaceable pods is the nearest equivalent in simplicity, and it creates less waste, though the first purchase of hardware costs more up front.
• Against nicotine replacement therapy such as patches, gum and lozenges. These are licensed medicines and a sound route for many people, though many smokers find vaping more satisfying because it replaces the hand-to-mouth habit.

What this product offers in value terms is a consistent, low-effort experience with two sensible flavour choices that suit people who like berries. Buying both flavours together is reasonable if you like to alternate, and cheaper per pod than separate one-off purchases where the listing offers a multi-pack price.

Where it is weaker is range and running cost for heavy users, and the fact that you are committed to one ecosystem. If you are not tied to the Mini Ultra device yet, think about whether you would be better off with a refillable kit. If you are, these pods make good sense.

Finally, price is not just money. A product that works first time and tastes consistent saves the time and irritation of returns, which counts too.

Storage, safety and recycling in the UK

Looking after pods and devices properly protects your health, your wallet and the environment, and it takes very little effort.

Storage. Keep unused pods upright in a cool, dry place away from direct sunlight and heat sources. A drawer or a pocket in a bag is better than a hot car, a windowsill or next to a radiator. Extreme heat can thin e-liquid and increase the risk of leaks, while cold can make the first few puffs sluggish. Aim for normal room temperature, roughly between 5 and 25 degrees Celsius.

Safety around children and pets. Nicotine is toxic if swallowed or absorbed through skin in quantity. Keep pods, packaging and devices out of the sight and reach of children and animals. If liquid gets on your skin, wash it off with soap and water; if it gets in your eyes, rinse thoroughly with clean water and seek medical advice. If anyone swallows e-liquid, call NHS 111 or 999 in an emergency.

Battery safety. The device contains a lithium-ion cell. Do not carry it loose with coins or keys, do not charge it on soft furnishings, do not leave it in a hot car and do not use a device that is swollen, cracked or unusually hot. Use a reputable charger and cable.

Recycling and disposal. A used pod and a worn-out device should never go into general waste or kerbside recycling. Lithium cells cause fires in bin lorries and sorting plants, and that has become a real problem across the UK. Instead:

• Take used pods and old devices to a vape recycling point. Retailers that sell vapes are expected to take used ones back, and many shops, supermarkets and recycling centres have dedicated bins.
• Use the small electricals or vape bin at your local household waste recycling centre.
• Check your council's website for the nearest drop-off point if you are unsure.
• Do not pierce, crush or burn pods or batteries.
• If a pod is leaking, put it in a sealed bag first, then take it to the drop-off point.

Recycling matters more than usual with this product type because it is the very reason pod systems exist. A device you keep and pods you recycle cut waste dramatically compared with discarded single-use bars. Making the drop-off a habit, for instance returning old pods when you collect a new order or stop at a drop-off point on your weekly shop, keeps the system working as it should.

Finally, remember the age rule. You must be 18 or over to buy, and our checkout and delivery process includes age checks. Please keep your pods and devices away from anyone who is not old enough to buy them.
