RELX Ultra Refill Pods Blueberry Sour Raspberry: what you are actually buying

These are replacement pods for a rechargeable closed-pod vape, not a complete device. Each pod is a sealed, pre-filled cartridge that holds the e-liquid, contains the heating coil and clicks into the matching battery unit. When a pod runs dry you pull it out, fit a new one and carry on with the same charged device. That simple swap routine is why refill pods have become the practical route for UK adult smokers since single-use disposables were banned in Great Britain in June 2025.

The flavour here is Blueberry Sour Raspberry. Think of a dark, slightly jammy blueberry base with a bright raspberry tartness layered on top and a sharp, sour finish that tingles at the sides of the tongue. It belongs to the fruit-forward end of the range and suits vapers who want something with a bit of bite rather than a flat, sweet berry.

A quick summary before we go deeper:

• Product type: pre-filled replacement pods for a rechargeable pod device; the battery unit is sold separately
• Flavour: blueberry with sour raspberry
• Typical capacity: about 2ml per pod, which is the maximum the UK allows for a pod or tank
• Nicotine: nicotine salt e-liquid, capped by UK law at 20mg/ml; pick your strength on the product page
• Coil: built into each pod, so every new pod brings a fresh coil with it
• Age: 18+ only, intended for adult smokers and existing vapers

One point to settle before you order: closed pods are device-specific. They only work in the battery unit they were designed for, so check the compatibility note on this page against the device you own. If you are unsure, send us a photo of your device and we will confirm the match before you buy.

Nicotine warning: this product contains nicotine, which is a highly addictive substance. It is intended for adults who already smoke or vape. If you do not currently use nicotine, please do not start.

In the sections below we cover flavour, puff delivery, build quality, coil and capacity, charging, nicotine strength, who the pods suit, how to use and recycle them, troubleshooting, value for money and how they compare with the alternatives. We have tried to stay practical and honest, including where these pods are not the right fit.

Flavour profile: blueberry depth with a sour raspberry edge

Flavour is the whole reason to pick this pod over a plain blueberry, so it deserves a proper description. The experience is easiest to understand in three stages: the inhale, the mid-draw and the exhale.

Inhale. The first note is blueberry, and it reads more like cooked fruit or preserve than boiled sweets. There is a slight dusky, darker quality to it, the kind you get from the skin of the berry rather than the juice. Sweetness is present but moderate, so it does not coat the palate with sugar.

Mid-draw. Raspberry arrives next, and this is where the tartness comes in. It is a bright, acidic raspberry rather than a creamy or candy-style one. If you have ever eaten raspberries straight from the punnet and caught the sharp seedy edge, that is the territory we are in. The sour element is layered over this, giving a citric tingle that sharpens the fruit rather than replacing it.

Exhale. The finish is a lingering mix of blueberry sweetness and sour raspberry. The tingle fades within a few seconds, leaving a clean fruit aftertaste. Because the name does not mention ice or menthol, you should not expect a strong cooling sensation. Any freshness comes from the acidity of the sour note rather than a cooling agent.

Some practical points about how the flavour behaves over time:

• Palate adaptation. Sour flavours often seem to soften after the first day or two as your tongue adjusts. This is normal and does not mean the pod has failed. Taking a short break, or drinking water between sessions, resets the effect.
• Consistency through the pod. A well-made pod should taste broadly the same from the first puff to the last. Expect the flavour to thin a little in the final stretch as the liquid level drops and the coil has less to work with.
• Strength and flavour interact. At 20mg/ml the throat hit is firmer and can mask some of the finer fruit notes. At lower strengths the fruit comes through more clearly.
• Temperature matters. Cold rooms or a pod left in a cold car make the liquid thicker, which mutes flavour for the first few puffs. Let it warm in your pocket first.

Who might not enjoy it? Anyone who dislikes sour sweets or tangy fruit drinks. If a sharp sherbet-style tingle is not your thing, a straight blueberry or a milder mixed berry will sit more comfortably. If you like fruit with some acidity, this is a sensible pick.

Performance and puff delivery

Closed-pod systems are designed to mimic the feel of a cigarette rather than to produce huge clouds. The draw is tighter than on a sub-ohm tank, vapour volume is moderate, and the nicotine delivery is steady rather than dramatic. If you are coming from cigarettes this is usually a good thing, because the sensation of a restricted, mouth-to-lung draw feels familiar.

Puff count. A pod holding roughly 2ml of nicotine salt liquid is commonly rated in the region of 500 to 700 puffs. Treat that as an estimate rather than a promise, because the real figure depends on how you vape. It works out at about 0.003 to 0.004ml of liquid per puff, which is plausible for short, gentle draws of two to three seconds.

Here is how that tends to translate into real life:

• Light use (a few sessions a day): one pod can stretch across two to three days.
• Moderate use (replacing 10 to 15 cigarettes a day): expect a pod to last about a day to a day and a half.
• Heavy or chain use: a pod can be gone in under a day, and at that point it is worth moving to a higher strength so you are not pulling constantly.

Manufacturers often compare a pod to a pack of 20 cigarettes. That is useful as a rough marketing shorthand, but nicotine delivery from vaping is not one-to-one with smoking, so work from your own habits rather than from the comparison.

What affects longevity:

• Draw length. Longer draws use more liquid per puff.
• Frequency. Taking puffs in quick succession heats the coil more and can burn through liquid faster.
• Ambient temperature. Cold liquid is thicker and can feel weaker, which tempts people to puff harder.
• Nicotine strength. A stronger pod is satisfying in fewer puffs, so it often lasts longer in practice for a given person.

Consistency. Pods with a regulated device give a steady output across their life, but the first draw after a long rest can feel slightly muted until the wick re-saturates. Taking one gentle draw before a proper pull helps. In the last stretch of a pod you may notice a warmer, thinner vapour, and if you ever taste anything burnt, stop using that pod and replace it rather than pushing through. A dry coil gives a harsh taste and is no use to anyone.

Design and build quality of the pod

A refill pod is a small component, but the engineering inside it decides whether it leaks, tastes right and clicks in cleanly. Here is what to look for and what to expect from a pod in this category.

Shell and window. The pod body is moulded plastic, usually semi-transparent, so you can see the remaining liquid at a glance. This is more useful than it sounds. Seeing the level lets you replace the pod before the coil runs dry rather than finding out by taste.

Mouthpiece. The mouthpiece is part of the pod itself. That means a fresh one every time you swap, which is better for hygiene than a reusable mouthpiece you have to clean. The opening is shaped for a gentle, closed-lip draw. If it feels narrow compared with a refillable tank, that is deliberate and part of the cigarette-like feel.

Connection. Pods in this class connect with a push-fit or magnetic seat and make an audible or tactile click when seated correctly. Gold-coloured or metal contacts on the base pass power to the coil. Keep those contacts clean and dry for reliable firing.

Sealing and leak resistance. Quality closed pods use silicone seals around the liquid chamber and the airflow channel. This is the main defence against leaks. Even so, no pod is completely leakproof when abused. Keep pods upright when you can, avoid squeezing the body, and do not leave them in hot places such as a parked car in summer.

Pack contents. Refill pods in this format are usually supplied as a multi-pod pack, commonly two pods per pack. Check the listing for the exact count before comparing prices, because per-pod cost is the number that matters.

Not designed for refilling. These are sealed, factory-filled pods. The fill port is not intended to be opened. Trying to prise them open and refill them risks leaks, damages the seals and can introduce the wrong liquid into a coil that was tuned for the original, and it will also void any returns or warranty claim. If you want to refill your own liquid, a refillable pod kit is the proper tool for that job.

Weight and pocketability. A pod weighs very little and the whole assembly with the battery unit is slim enough for a jeans pocket. Carry spare pods in the original packaging or a small hard case so the contacts do not pick up lint or debris.

Coil technology and e-liquid capacity

The coil is the part that turns liquid into vapour, and in a closed pod it is built into the cartridge. That is a big part of the appeal: you never touch, prime or replace a coil separately. Every pod swap is also a coil swap.

Coil type. Pods in this category generally use either a ceramic-core heating element or a mesh coil. Both aim at the same outcome, which is even heating across a larger surface area so the liquid vaporises smoothly without hot spots. Ceramic wicking tends to give a clean, consistent flavour and good resistance to dry hits. Mesh offers quick ramp-up and good vapour production. The specification table on this page is the place to confirm the exact element used in this pod, and the practical advice below applies either way.

Resistance and power. Closed-pod coils typically sit in the 1 to 2 ohm range and run at low wattage, often under 10W. That low-power approach is part of why these devices are efficient with nicotine salts, and why they feel gentle compared with a high-power refillable kit.

Capacity. UK regulations limit a pod or tank to 2ml, and pods in this format are built to that ceiling. That is why you will see pod sizes cluster at around 1.8 to 2ml. The small capacity is a regulatory limit rather than a design weakness, and the answer for heavy users is simply to carry a spare pod.

E-liquid composition. Nicotine salt liquids are blended from propylene glycol, vegetable glycerine, nicotine, flavourings and an acid, which is how nic salts stay smooth at higher strengths. Pod liquids often lean towards a higher proportion of propylene glycol, which carries flavour well and wicks quickly at low power. If you are sensitive to propylene glycol (some people notice a dry throat), ask your pharmacist or GP for advice.

Coil lifespan and flavour fade. Fruit and sour flavours contain sweeteners and acids that can slowly darken the wick and coil as the pod empties. You may notice the flavour gently dulling in the last quarter of the pod. This is normal ageing of the coil rather than a fault. If the taste turns unpleasant or burnt, replace the pod.

Why this suits you if... you want zero maintenance. There is no wicking, no priming of a new coil head, no cotton to burn. The trade-off is that you cannot tune the output or swap in a different coil, so what is in the pod is what you get.

Battery and charging: the device side of the equation

The pods themselves do not contain a battery. Power comes from the rechargeable unit that the pod clicks into, so this section is really about the device these pods are paired with. Exact specifications vary by model, so check the device listing and manual, but the principles below hold for the category.

Battery size. Slim closed-pod devices usually carry a battery somewhere between about 350 and 500mAh. That is deliberately modest, because the aim is pocket size and low power draw. It is enough for a day of light to moderate use for many people, but heavier users should plan to top up.

How often to charge. As a rough guide, expect to recharge about once per pod, and sometimes a little more often if you vape heavily. A simple routine works well: when you swap to a fresh pod, plug the device in for a top-up at the same time. That way you rarely get caught out.

Charging time. Most compact pod devices recharge in roughly an hour to an hour and a half. Many use a USB-C connection, though some use a proprietary dock, so check your model. LED indicators usually show charging status; the colours and blink patterns differ between devices, so refer to the manual.

Sensible charging habits:

• Use the cable supplied with the device or a reputable replacement, with a standard 5V phone-style adapter.
• Do not charge under a pillow, on a bed or on a sofa where heat cannot escape.
• Unplug once the device is full rather than leaving it for days.
• Do not charge a device that is wet, damaged or has a swollen case.
• Stop using any device that becomes unusually hot during use or charging, and dispose of it through an electrical recycling point.

Charging with a pod fitted. Most devices of this type can charge with a pod in place, but if you are travelling, it is good practice to charge with the pod removed to reduce the chance of residual liquid seeping into the charging contacts.

Battery ageing. Like any lithium-based battery, the unit will slowly lose capacity over hundreds of charge cycles. If you find you are charging noticeably more often after a year or so, that is normal wear. Replacement is cheaper than it sounds, since the battery unit is the long-term part and the pods are the consumable.

Nicotine strength guidance for UK vapers

Choosing the right strength is the most important decision you make with a nicotine pod, because getting it wrong either leaves you craving cigarettes or leaves you feeling unwell. This is general guidance, not medical advice.

The UK limit. Under UK vaping rules, nicotine e-liquid is capped at 20mg/ml (2%). The same 20mg cap that applied to disposables applies to every pod, bottle and refill sold for vaping. These pods are therefore at or below that ceiling. Refill containers are also limited to 10ml and tanks or pods to 2ml, which is why pod sizes are what they are.

What the numbers mean. A 2ml pod at 20mg/ml contains 40mg of nicotine in total, and at 10mg/ml it contains 20mg. You do not absorb all of it. A cigarette delivers only a small amount of nicotine to the bloodstream, and vaping delivers it differently, so milligram comparisons with cigarettes are only a rough guide.

How to choose:

• 20mg/ml: suited to people who smoke around 10 or more cigarettes a day, or who wake up needing a cigarette quickly. Nicotine salts are smoother than freebase at this level, but the throat hit is still firm.
• Mid strengths (around 10 to 12mg/ml, where offered): suited to lighter smokers, social smokers or people stepping down. If you used to smoke 5 to 10 a day, begin here.
• Lower strengths: useful for the final phase of reducing nicotine intake, or for existing vapers who find higher strengths too harsh.

Check the strength selector on this page for what is available, since not every flavour is stocked in every strength.

Signs it is too strong: dizziness, nausea, headaches, a racing heart, hiccups, or a harsh throat. If this happens, stop and choose a lower strength next time.

Signs it is too weak: constant puffing, nagging cravings, a pod that disappears within hours, or slipping back to cigarettes. Move up one step.

Stepping down. If your aim is to reduce nicotine over time, a gradual approach works best. Stay on a strength for a few weeks, and only move down one step when you feel comfortable. The NHS Better Health stop smoking service and local stop smoking services offer free support and can advise on combining vaping with other aids.

Who should avoid nicotine entirely: anyone under 18, anyone pregnant or breastfeeding without medical advice, and anyone who has never smoked. Nicotine is addictive and these pods are meant to help adult smokers move away from tobacco.

Who these pods are for, and who should look elsewhere

Being clear about the right customer saves everyone time and returns. Here is an honest picture.

These pods suit:

• Adult smokers switching from cigarettes who want a simple, low-fuss device. A restricted, mouth-to-lung draw feels closer to a cigarette than a big sub-ohm cloud.
• Existing RELX-style closed-pod users who want a new flavour for the same device and prefer fruit with some tartness.
• Former disposable users. Since single-use disposables were banned, many people have moved to rechargeable pod kits. Swapping a pod is the nearest equivalent to opening a fresh disposable, but with far less waste.
• People who want predictable, no-maintenance vaping: no fill port, no coil changing, no spilled liquid on your fingers.
• Vapers who like sharp, fruity flavours and want a change from menthol or sweet dessert profiles.

You might prefer something else if:

• You want big clouds or a loose draw. A closed pod will feel restrictive. A refillable sub-ohm or pod-mod kit is a better match.
• You want to save money per millilitre. Pre-filled pods cost more than bottled e-liquid. If you are happy to refill, a refillable kit is cheaper to run.
• You dislike sour tastes. This flavour is deliberately tangy. A smoother berry will be a better daily choice.
• You do not already smoke or vape. Nicotine products are for adults who currently use tobacco or nicotine. If you do not, we would ask you not to start.
• You are under 18. It is illegal to sell nicotine vapes to anyone under 18, and we will not do so.
• You own a different pod system. Pods are not interchangeable across brands. Check compatibility first.

A note on switching. If you are moving from smoking, many people find it easiest to switch completely rather than do both, because dual use keeps the tobacco habit alive. Vaping is not risk-free, but it is widely considered substantially less harmful than smoking for adults who switch fully. If you want structured support, your local NHS stop smoking service is free.

If you fall into the middle ground and are not sure which category you belong to, our team can talk you through it. Just tell us what you smoke or vape now and what you want to change.

How to use, store and recycle your pods

Using a closed pod is simple, but a few habits keep it tasting right and prevent leaks.

Fitting a new pod:

• Check the pod packaging is intact, then remove any protective film, cap or seal from the pod, particularly around the mouthpiece and the base.
• Line the pod up with the opening in the device and push it in until it seats or clicks. If it will not go in smoothly, do not force it. Re-check alignment and compatibility.
• Wait a minute or two before the first puff. This gives the wick time to soak up liquid.
• Take one or two gentle priming draws without inhaling deeply, then start normally.

Drawing technique. Use a slow, steady two to three second draw with your lips sealed around the mouthpiece, hold briefly in the mouth, then inhale to the lungs if that suits you. Avoid short, sharp pulls. They produce less vapour, deliver less flavour and can make the pod seem weaker than it really is. Leave a few seconds between puffs so the coil can re-wet.

Replacing a pod. Pull the empty pod straight out, fit the new one, and wipe the contacts on the device with a dry cotton bud if they look dirty. Never use water or cleaning sprays on the contacts.

Storage:

• Keep spare pods upright, in their packaging, at room temperature.
• Keep out of direct sunlight, away from radiators and away from freezing temperatures.
• Keep all vaping products and nicotine liquid locked away from children and pets.
• Carry spare pods in a small case in your bag rather than loose in a pocket with keys or coins.

Using pods safely. Do not use a pod that is cracked or leaking. If liquid gets on your skin, wash it off with soap and water. If it gets in your eyes, rinse with plenty of water. If anyone swallows liquid, contact NHS 111 or call 999 in an emergency.

Recycling. Do not put used pods or devices in your household bin or mixed recycling. Pods contain residual liquid and a small coil, and the battery unit contains a lithium cell, both of which can cause fires in waste lorries. In the UK, shops that sell vaping products are required to take back used vapes and related waste electrical items, and many household recycling centres have a dedicated small-electricals container. Look for a vape drop-off point near you or ask at the counter. Never try to dismantle the battery.

Troubleshooting common problems

Most issues with closed pods have simple fixes. Work through these before assuming a pod is faulty.

• Weak or muted flavour. Check the pod is fully seated, give it a minute to prime and take a couple of gentle draws. If the liquid window shows the pod is nearly empty, that is the likely cause. Palate fatigue with sour flavours is also common, so switch to water for a few hours.
• Burnt or harsh taste. This usually means the coil is dry or overheating. Stop using the pod. Do not keep puffing in the hope it clears, and do not chain vape. Fit a new pod.
• No vapour or the device will not fire. Check the battery first. Charge it fully, as a low battery is the usual culprit. Then remove the pod, clean the contacts with a dry cotton bud and refit it. Make sure all protective seals have been removed.
• Device lights flash or show an error. Flash patterns differ between devices and generally indicate a low battery, an unrecognised pod, a short circuit or a protection cut-off. Check your manual. If the pod is not detected, try reseating it, and if that fails try a different pod to rule out a one-off defect.
• Gurgling or spitting. Excess liquid has built up around the coil or in the airway. Remove the pod, give the mouthpiece a gentle blow to clear it, wipe any liquid away and refit. Take slower draws.
• Leaking from the base or the device. Wipe the pod and the device, let them dry, and keep the pod upright. Pods that have been squeezed, dropped or exposed to heat are more prone to leak. If a new pod leaks straight from the pack, contact us with a photo.
• Hard draw. The airflow slot may be blocked by lint or a film of liquid. Remove the pod and clear the opening. Do not insert pins or sharp objects.
• Sweet liquid taste on your lips. This may be condensation or leakage into the mouthpiece. Clear it as described under gurgling and keep the device upright between sessions.
• Pod runs out too fast. Check your technique, as long draws and chain puffs use more liquid. If you are still vaping constantly, move up in strength.
• Hot device. Stop using it, unplug if charging and let it cool. If it repeats, stop using it altogether and recycle it safely.

If you have tried these steps and the pod still does not perform, keep the packaging and the pod and get in touch with your order number. We will look into it under our returns terms and your statutory rights.

Value for money

Value is a combination of price per pod, how long each pod lasts and what you are comparing it with. Here is a clear way to work it out rather than relying on a headline price.

Step one: price per pod. Take the pack price and divide it by the number of pods. If a pack holds two pods, a pack at £10 means £5 per pod. Ignore multi-buy discounts until you have worked out the base figure.

Step two: price per day. Estimate how many days a pod lasts for you. As covered above, a moderate user might get a day to a day and a half from a 2ml pod, and a lighter user two to three days. Divide the per-pod price by those days.

Step three: compare with what you spend now. A pack of 20 cigarettes now costs well over £14 in most UK shops, so a person smoking a pack a day is spending upwards of £5,000 a year. A pod habit that costs a few pounds a day is significantly cheaper, even before you account for the other costs of smoking.

Closed pods are not the cheapest way to vape, and it would be dishonest to say otherwise. You pay for convenience:

• Pre-filled pods cost more per millilitre than bottled liquid, but need no refilling, no coil changes and no cleaning.
• Refillable kits cost less to run but need a learning curve, spare coils and a place to keep bottles.
• Disposables are now banned in Great Britain, and in any case created much more waste for the same amount of vaping. A rechargeable device plus pods avoids throwing away a battery with every purchase.

Where the value really sits. The battery unit is the long-term investment and the pods are the consumable. A device you keep for a year or more spreads its cost thinly, and the only recurring spend is pods. Buying in multi-packs usually reduces cost per pod, but only buy as many as you will use in a sensible time, since e-liquid has a shelf life.

Authenticity and freshness. Cheap pods from unverified sources are a false economy. Counterfeit pods may leak, taste off or contain unknown liquid. Buy from a reputable UK retailer, check the packaging for a batch code and the required health warnings, and be wary of anything that looks too cheap.

If you want to cut costs further without moving to a refillable kit, choose the strength that actually matches your needs. Over-strength pods get used faster than they need to, and under-strength pods lead to constant puffing. Getting the strength right is the cheapest improvement you can make.

Honest comparisons: how this stacks up against the alternatives

No pod is right for everyone, so here is a fair comparison with the main alternatives a UK vaper might consider.

Versus other flavours in the same range. If you like blueberry but not sourness, a plain blueberry or a mixed berry will be gentler. If you like menthol or ice, there are cooler options in the same family. This pod is the one to pick if tangy fruit is the point.

Versus other closed-pod systems. Systems such as Vuse ePod, Blu and ELFA-style pod kits follow the same principle: sealed pods, a rechargeable battery and a simple swap. Differences come down to coil design, flavour selection, pod price and availability of strengths. The strongest argument for staying within one ecosystem is that your existing device keeps working, and the pods are not cross-compatible, so switching brand means buying a new battery unit as well. If you already own the matching device, there is little reason to change purely for a flavour.

Versus refillable pod kits. Refillable kits from brands such as SMOK, Vmate-style systems and others let you pour in bottled nicotine salt liquid. They are cheaper per millilitre, offer a far wider range of flavours and let you pick any strength up to 20mg/ml. The downside is handling liquid, replacing coils and occasional leaks. If you value simplicity, closed pods win. If you value cost and choice, a refillable kit wins.

Versus the old disposables. Disposables could offer a lot of puffs, but they ended up in landfill with a lithium battery inside, and they have been banned since June 2025 in Great Britain. Rechargeable pod systems deliver a similar convenience with less waste and a longer-lasting battery.

Versus nicotine pouches and NRT. Pouches, patches, gum and inhalators serve a different need. They do not replicate the hand-to-mouth habit of smoking, but they are useful for places where you cannot vape or as part of a stop smoking plan. Some people use both. Your local pharmacist or stop smoking service can advise on combinations.

Honest limitations of this pod:

• It is a sealed unit, so no tweaking of airflow or power.
• The 2ml capacity is the legal limit and means regular swapping for heavy users.
• Sour flavours are polarising. Some people love them, others tire of them within days.
• Pods only work in compatible devices.

Bottom line. For an adult smoker or vaper who wants a simple, tidy way to enjoy a tangy blueberry and raspberry flavour in a compatible rechargeable device, it does the job cleanly. If your priorities are low running cost, big vapour or maximum flavour choice, a refillable kit is a better route.
