RELX Ultra Refill Pods Tropics Shake: what you are buying

RELX Ultra Refill Pods in Tropics Shake are pre-filled, sealed replacement pods for a RELX Ultra style closed pod device. You do not pour e-liquid into them, you do not rebuild or prime a coil, and you do not change any settings. You take the old pod out, click the new one in, and carry on. Tropics Shake is the creamy fruit option in the range: a tropical fruit blend with a smooth, milkshake-style body, rather than the sharp, watery profile you get from an icy fruit pod.

It helps to be clear about the product category before you order. This is a refill pod, not a complete vape. The pod holds the e-liquid and the heating coil. The battery, the draw activation and the charging port all live in the device. If you do not already own a compatible device, a pod on its own will not do anything, and you will need to buy the device first.

• Flavour: tropical fruit with a creamy, shake-style finish
• Format: pre-filled closed refill pod, no filling and no coil changes
• Capacity: UK-sold pod systems are limited to 2ml of e-liquid per pod, so 2ml is the sensible planning figure
• E-liquid type: nicotine salt, which is smoother on the throat than freebase nicotine at the same strength
• Nicotine: never above the UK maximum of 20mg/ml (2%); choose the strength offered on this page that suits your habit
• Pack size: refill pods in this range are normally sold in multi-pod packs, so check the pack quantity shown in the listing before comparing prices

One compatibility point is worth stating plainly. Closed pod systems are not universal. A pod is built to fit a particular connector, and pods from different generations or different brands do not interchange. Before you buy, check the compatibility line on the product page and on the packaging of your current pods, and make sure the pod you are ordering is designed for the device you actually own. If you are unsure, ask us before ordering, because an opened pod that does not fit is not something we can restock.

The rest of this guide covers what to expect from the flavour, how long a pod tends to last, how the device and pod work together, how to choose a nicotine strength, what to do if something goes wrong, and how this pod compares fairly with other options. We have tried to say what we do not know as clearly as what we do, because exact manufacturer specifications vary by pod generation and are not always printed in the same place.

Tropics Shake flavour profile: what it actually tastes like

The name does most of the describing. Tropics points to a mixed tropical fruit base, and Shake points to a creamy, rounded texture on top of it. Flavour houses do not publish their recipes, so we cannot give you an ingredient list, but the general impression of a flavour in this style is consistent enough to describe honestly.

On the inhale, expect sweet, juicy fruit first. Tropical blends usually lean on the sweeter end of the fruit spectrum, so think ripe, soft fruit rather than tart or sour notes. As the vapour moves across your tongue, the creamy element comes in and softens the fruit, which is what separates a shake-style flavour from a plain tropical juice. On the exhale the fruit tends to linger lightly while the cream gives a smooth, slightly thick finish. There is no menthol or cooling agent in the name, so do not expect an icy hit; if you want chill, look at the ice variants in the range instead.

• First impression: sweet, ripe tropical fruit
• Middle: a creamy, smooth body that rounds off any sharpness
• Finish: soft fruit with a lingering dessert-like sweetness
• Throat hit: gentle, helped by the nicotine salt formulation and the creamy base
• Cooling: none implied

Be realistic about two things. First, sweetness. Creamy fruit flavours are built on a sweet base, and after a long session they can read as rich or heavy. Vapers who prefer dry, crisp flavours sometimes enjoy the first few puffs of a pod more than the last few. If that sounds like you, rotate Tropics Shake with a sharper citrus or berry pod so your palate does not tire of it.

Second, texture. Cream-style flavourings can leave a slightly coated feeling in the mouth, and they tend to build up residue on a coil faster than a clear fruit liquid does. That does not mean a problem with the pod; it is a known trait of dessert and shake flavours. Sipping water between sessions and avoiding chain vaping keeps the flavour cleaner for longer. We describe perceived flavour as accurately as we can, but taste is personal, and what reads as creamy mango to one person can read as coconut or vanilla-fruit to another.

Performance and puff delivery

Manufacturers often print a single puff figure on packaging, but real-world puff counts depend on how long each draw lasts, how often you vape, which nicotine strength you use and how much power the device delivers. Rather than repeat a headline number, it is more useful to work out what 2ml of liquid represents and plan from there.

A typical short draw on a mouth-to-lung pod device uses somewhere in the region of 0.003 to 0.005ml of e-liquid, with longer or harder draws using more. Dividing 2ml by that range gives a span of roughly 400 to 650 puffs per pod. A cautious planning figure for most people is about 400 to 600, and you should treat anything much higher as a best case achieved with very short, infrequent draws.

• Heavy smokers (around 20 cigarettes a day): expect a pod to last roughly a day, sometimes slightly less in the first week while you settle into the device
• Moderate smokers (10 to 15 a day): a pod will commonly last one to two days
• Light or social users: a pod can last several days, though you should still replace it if the flavour fades or the liquid level looks low

Several habits shift those figures. Taking long, slow draws uses more liquid per puff. Chain vaping, where you take puff after puff without a pause, heats the coil harder and drains the pod faster while also making the flavour taste hotter and flatter. A higher nicotine strength usually means fewer puffs are needed to feel satisfied, which stretches a pod, while a lower strength tends to prompt more frequent use.

Consistency across the life of the pod matters as much as the total. A well-made pod should deliver roughly the same flavour and vapour on puff 50 as on puff 350. With creamy flavours, you may notice the last stretch of a pod tasting a little more muted or slightly sweeter, because the coil is working with less liquid and any residue is more noticeable. When flavour drops off suddenly, that is usually a sign the pod is close to empty and should be swapped rather than pushed further, since vaping a nearly dry pod is how burnt tastes happen.

The draw style is close to a cigarette: a gentle mouth-to-lung pull with moderate resistance. Vapour volume is modest. If you want large clouds, a sub-ohm kit is a better fit; this pod is designed to be discreet and to deliver nicotine in a cigarette-like way.

Design and build quality of the pod

A refill pod is a small component, but the build decides whether your experience is clean or messy. The things to look at when you unpack a pod are the mouthpiece, the seal, the connector end and the body, and a quick inspection takes a few seconds.

• Reservoir: sealed and pre-filled, so there is no fill port to leak from and nothing to unscrew. Depending on the pod, you may be able to see the liquid level through the body, which helps you judge when to replace it
• Mouthpiece: shaped for a comfortable, lip-friendly fit. It is intended to be drawn on gently, like a cigarette, not pulled hard like a sub-ohm tank
• Connector: the end that seats into the device should engage with a firm, definite fit. If it feels loose, gritty or needs force, take it out and check for debris rather than pushing harder
• Body: lightweight plastic construction is normal in this category, which keeps the pod light and the whole device pocketable

Before first use, check that any protective plug or film at the base or mouthpiece has been removed as the packaging instructs. Some pods ship with a small cap or seal to prevent leaks in transit. Leaving it on is the most common reason a brand-new pod appears not to work. Also check that the pod looks undamaged: a cracked body, a visibly tilted wick area or liquid pooling in the packaging are reasons to contact us instead of using it.

Leaks in pod systems are rarely caused by the pod design alone. They usually come from heat, pressure or storage. Leaving a device in a hot car, in a pocket close to your body for long periods, or on its side with the pod pointing down can push liquid towards the airway or connector. Creamy, slightly thicker liquids are not more leak-prone by nature, but any residue that does escape tends to be sticky, so wipe the connector contacts with a dry tissue if you spot it.

We would rather be honest than overstate materials. We cannot tell you the exact plastic or internal construction of every pod batch, and the manufacturer information on the pack is the right place to check. What you can judge for yourself is fit, finish and the absence of loose parts, and a pod that fails that quick inspection should not be used.

Battery and charging: what the device does for the pod

The pod has no battery of its own. Power comes from the device, so the pod's performance is partly a function of how healthy and how charged the device battery is. Understanding this saves you from blaming a good pod for a flat device.

Slim, pocketable devices in this category typically use cells in the region of a few hundred milliamp-hours, with larger models reaching somewhere around 500 to 700mAh. We do not state an exact capacity for your device because it varies by model, and the figure in the device manual or on the manufacturer page is the one to rely on. As a rough guide, a few hundred mAh is enough to get through a good part of a day for a moderate user, while a heavy user may need a top-up charge mid-day.

• Charging port: modern devices generally charge over USB-C, using a standard cable. Check which connector your device uses
• Charge time: small cells usually need somewhere between 30 and 90 minutes from low to full; consult your device manual for its specific figure
• Indicator light: most devices show charge state or low battery by a light colour or pattern; learn what yours means
• Pod changes: you do not need to charge when you change pods, but it is good practice to top up at the same time so the pod and battery run out around the same time

A low battery affects flavour before it stops the device completely. As voltage sags, the coil does not reach its usual temperature, and a creamy fruit flavour in particular can taste thin or muddy. If Tropics Shake tastes weaker than it did yesterday, charge the device before deciding the pod is at fault.

Charging safety is straightforward and worth following. Use the cable supplied or a quality replacement, and a plug from a reputable maker rather than an unbranded one. Do not leave a device charging unattended on a soft surface such as a bed or sofa, do not charge a device that is damaged, swollen or unusually hot, and do not carry a device loose in a bag with keys or coins. If the battery seems to be failing, stop using the device and take it to a proper recycling point rather than the bin.

Coil and mesh technology inside the pod

The heating element in a refill pod is the component that turns liquid into vapour, and its design influences flavour, longevity and the risk of burnt tastes. Pod coils fall broadly into a few families: ceramic-based heaters, mesh coils and traditional wire-and-cotton coils. The exact construction varies by generation and by manufacturer, and brands do not always spell it out on packaging. We would rather tell you that than invent a specific material, so check the pack or the manufacturer's information for the exact construction of the pod you receive.

What we can explain is why coil design matters for a flavour like Tropics Shake.

• Even heating: a wider heating surface warms the liquid more uniformly than a thin wire, which tends to produce steadier flavour and fewer hot spots
• Wicking: the coil is paired with an absorbent wick that draws liquid in from the reservoir. Creamy, slightly thicker liquids need a wick that can keep up, otherwise the coil dries out between puffs and tastes harsh
• Resistance: closed pod coils for mouth-to-lung draws typically sit somewhere around 1 to 1.5 ohms, which pairs with a small battery to deliver a gentle, cigarette-like vapour rather than a large cloud
• Low temperature: sweet and creamy ingredients caramelise if the coil runs too hot, so a sensible operating temperature protects flavour

For shake and dessert style liquids, residue is the main long-term concern. Sweeteners and creamy flavourings can leave a thin film on the coil surface as liquid is vaporised, and as that film builds, flavour dulls and a slightly toasted note can creep in. Since the coil sits inside a disposable pod, you never clean it; the pod is replaced before the build-up becomes a problem. That is the practical benefit of the closed pod format and one reason why replacing a pod on time beats trying to stretch it.

You can slow residue build-up with simple habits. Take moderate draws of two to three seconds, leave a pause between puffs so the wick re-saturates, and never keep drawing on a pod that is clearly running dry. If you hear a crackle or taste a dry, scorched note on a pod that still looks partly full, give it a minute, take a gentler puff, and if the problem repeats, replace the pod.

Finally, remember that nicotine salt formulations are designed to work at the lower power levels that small pod devices produce. They deliver a satisfying hit without needing the high wattage of a larger vape, which is one reason a compact coil is enough.

Nicotine strength guidance for UK vapers

UK law caps the nicotine strength of consumer vape liquids at 20mg/ml, which is 2%. You will not find Tropics Shake pods stronger than that from a legitimate UK retailer, and if you are offered something higher, treat it as a red flag. Choose from the strengths shown on this page, and check the label on the pack when it arrives.

Nicotine salts feel smoother than freebase nicotine at the same percentage, which is why a 20mg/ml salt pod rarely feels as harsh as a 20mg/ml freebase liquid would. That smoothness is useful, but it also means it is easy to take in more nicotine than you intended, because the throat does not warn you as quickly. Use your own comfort as the guide.

• 20mg/ml (2%): the highest legal strength, aimed at heavy smokers (around 15 or more cigarettes a day) who need a cigarette-like hit from the start
• 10 to 12mg/ml: suits moderate smokers, or people who find 20mg/ml too strong. Smoother and usually longer-lasting per pod because you vape less often
• Lower strengths where available: for light or social smokers, or those stepping down. If you are unsure, start lower, because it is easier to go up a strength than to recover from taking too much

As a starting rule, match the strength to what you smoke now. If you smoke a pack a day, 20mg/ml is the usual starting point; if you smoke about half that, a middle strength is more likely to feel comfortable. If you have never smoked, you probably do not need to start vaping at all, and we would encourage you not to.

Signs the strength is too high include dizziness, headache, nausea, a racing heartbeat or a feeling of being unwell after a few puffs. If that happens, stop, drink water, and move down a strength. Signs it is too low include constantly reaching for the device, taking long draws to feel satisfied, and still craving a cigarette. Adjust in one step at a time and give each change a few days.

Nicotine is addictive. These pods are intended for adult smokers and existing vapers aged 18 or over. They are not suitable for under-18s, non-smokers, or anyone who is pregnant or breastfeeding, and anyone with a heart condition or other medical concern should speak to a doctor or pharmacist. We do not make medical claims about stopping smoking; this is general information to help you buy the right strength, not medical advice.

Who RELX Ultra Tropics Shake pods are for, and who should skip them

No flavour suits everyone, and being upfront about fit saves you money. Tropics Shake is a particular style of pod, so it is worth thinking about whether that style matches what you are looking for.

These pods suit you if:

• You already use a compatible RELX Ultra style device and want a straightforward replacement pod
• You like sweet, smooth, dessert-leaning flavours and want something softer than a sharp fruit or mint pod
• You are a current smoker or existing vaper who prefers a cigarette-like draw over big clouds
• You value convenience: no filling, no coil changes, minimal fuss
• You want a flavour that is easy on the throat at a given nicotine strength

You should look elsewhere if:

• You prefer cold, crisp, citrus or menthol flavours; an ice or mint pod will suit you better
• You do not own a compatible device, because the pod cannot be used on its own
• You want large clouds or a very customisable setup; a sub-ohm kit with your own liquids is a better fit
• You find very sweet flavours cloying over long sessions
• You are under 18, do not currently smoke or vape, or are pregnant or breastfeeding
• You want the lowest possible running cost and are comfortable with refillable systems, which are cheaper per ml but need more handling

There is also a middle group: people who like the idea of a creamy fruit flavour but are not sure. For them, the sensible approach is to buy a small pack first rather than a large multi-pack, try it across a few days of normal use, and then decide. Flavour fatigue is real, and many regular vapers keep two flavours in rotation, for example one sweet pod like this and one sharper pod, swapping between them to keep things interesting.

If you are moving from disposables, note that a pod system gives you a more stable experience over the life of the product, because you replace the coil with each pod instead of living with one coil until the device is thrown away. Many people find that this is a more economical and more sustainable way to vape, as long as you recycle the used pods properly.

How to fit, use and look after the pods

Using a refill pod is simple, but a few small habits make the difference between a clean first puff and a gurgling, leaky or burnt one. Follow the steps below, and treat the device manual as the final word if it differs.

• Step 1, switch the device off or put it down upright: if your device has a lock or an off setting, use it before changing the pod
• Step 2, remove the old pod: pull it straight out or release it as the design requires, without twisting or squeezing the body
• Step 3, check the new pod: remove any protective cap, film or plug, and look for visible damage
• Step 4, seat the new pod: push it straight in until it clicks or sits flush, keeping the pod and device upright
• Step 5, let it rest: give a fresh pod a minute or two so the wick can saturate with liquid before you draw on it
• Step 6, take a gentle first draw: take one or two short puffs rather than a long hard pull to avoid dry hits

For day-to-day use, aim for smooth, moderate draws of two to three seconds and leave a few seconds between puffs. Do not chain vape. If you want to take a big session, split it into a few smaller ones across the day. Keep the device upright when you can, and store it in a cool, dry place out of direct sunlight, away from heat sources, and out of the reach of children and pets.

Spare pods should be kept in their sealed packaging until you need them. Unopened pods stored in a cool, dry place generally stay in good condition for a long time, but check the best-before date on the pack and use older stock first. When travelling, keep pods upright where you can, because pressure changes in a plane can push liquid around and cause minor seepage. A small zip bag in a pocket or hand luggage contains any mess.

When it is time to change a pod, do it before the flavour collapses rather than after. Signs it is time: the visible liquid level is low, flavour has flattened, vapour has thinned, or you taste a hint of burnt sugar. Do not try to refill a closed pod. Pods are designed to be sealed, refilling them can damage the coil and seal, and it risks nicotine spills. Wipe the connector end of the device with a dry tissue each time you change pods, and use a dry cotton bud if there is any visible residue on the contacts.

Troubleshooting: common problems and what to do

Most pod problems are simple and fixable. Work through the likely causes in order before assuming the pod is faulty.

• No vapour or no response: check the pod is fully seated, remove and reseat it, make sure the device is charged and switched on, and confirm the pod contacts are clean and dry. If nothing happens after changing the pod, try a second pod to rule out a single defective one
• Weak or muted flavour: charge the device first, because a low battery thins flavour. Then check the liquid level; a nearly empty pod tastes flat. Also consider flavour fatigue, as sweet flavours can seem to fade after days of use even when nothing is wrong
• Burnt or acrid taste: usually caused by chain vaping, very long draws, or vaping a pod that is nearly empty. Rest for a few minutes, take a gentler puff, and replace the pod if the taste persists
• Gurgling or spitting: excess condensation in the airway. Remove the pod, wipe the mouthpiece and connector, and take a couple of gentle puffs to clear it
• Leaking: check the pod is seated correctly and has not been damaged, wipe the contacts, and store the device upright. If a new pod leaks straight out of the pack, keep it and get in touch
• Hard to draw on: make sure no cap or film is blocking the airflow and the pod is seated correctly. A blocked airway can also come from condensation or lint in a pocket
• Device flashing or refusing to fire: flashing lights can indicate a low battery, a poor connection or a lock mode. The device manual explains the exact meaning of each pattern
• Sticky or tacky connector: wipe it dry. Creamy flavours can leave a slightly sticky residue if liquid escapes

If you have been through that list and the pod still does not work in a device you know is in good condition, it may be a defective pod. Keep the pod and its packaging, note your order number, and contact us with a short description. A photograph of the problem is useful. We would rather resolve a faulty pod than leave you with a poor experience.

Equally, if a pod has an unusual smell, a leaking body, damaged seals or visible debris in the liquid, do not use it. Safety comes before value. Wash any liquid off your skin with soap and water, and if it gets in your eyes, rinse with plenty of water and seek advice. Keep nicotine liquids away from children and pets at all times.

Value for money and honest comparisons

The simplest way to judge value is to turn the pack price into a cost per day. Work out how many pods you use per week, multiply by the per-pod price on this page, and compare it with what you currently spend. A pack of 20 cigarettes in the UK now costs well over fifteen pounds, so a pod system that replaces most of your smoking will usually cost less than smoking, even though it will cost more than refillable vaping.

Where pre-filled pods sit against other options depends on what you value.

• Versus single-use disposables: disposable vapes were banned from sale in the UK from 1 June 2025, so the realistic comparison is with pod and refillable systems. A refill pod gives you a re-usable device and a smaller amount of waste per puff
• Versus refillable pod kits and sub-ohm kits: pre-filled pods cost more over time but remove the mess and the learning curve. Refillables are cheaper per millilitre and offer far more choice of flavours and strengths, but need handling, coil changes and a bit of knowledge
• Versus other closed pod systems: brands such as Vuse, blu and Smok offer pre-filled closed pods with their own devices. Each has its own pod design and flavour range, and differences in price, availability and flavour quality are real but vary by flavour and batch. We would not claim RELX Ultra beats all of them; the practical advantages are the familiar, simple format and the choice of flavours, and the main drawback is that it ties you to one connector
• Versus other RELX flavours: Tropics Shake is the sweet, creamy end of the range. If you prefer a brighter, tangier fruit profile, a blend such as mango and pineapple is crisper, and if you want cold, an ice variant is the better choice

Buying multi-packs, where offered, often reduces the per-pod cost, and buying from a UK retailer with clear stock information makes it easier to reorder the same pod when you need it. Check the per-pod price rather than the pack price when comparing, because pack sizes vary. Be cautious about prices that look far lower than other UK stockists, since unusually cheap vape products can be counterfeit, expired or unsuitable for the UK market.

The honest summary: Tropics Shake offers reasonable value if you already own the device, enjoy sweet creamy flavours and want a simple routine. It is less compelling if you are cost-focused and comfortable with refillable systems, or if you want to experiment with lots of flavours without being tied to one pod type.

UK rules, recycling, delivery and buying safely

Vaping products sold in the UK are regulated, and knowing the basics helps you buy safely. Nicotine strength in consumer vape liquids is capped at 20mg/ml, and the tanks and pods of refillable and closed pod systems are limited to 2ml. Packaging must carry the standard nicotine health warning, and products should show the manufacturer's details and a batch reference. These pods are for adults only. You must be 18 or over to buy, and orders may need an age check at checkout or on delivery.

A word on terminology. Single-use disposable vapes were banned from sale in the UK from 1 June 2025, so you will not see them stocked by a compliant UK retailer. Refill pods are a different product because they are designed to be replaced inside a re-usable device, and they remain on sale. If a retailer is selling something presented as a disposable, ask why.

Recycling matters for pod systems. A used pod contains a heating element, a little residual liquid and plastic, and the device contains a lithium battery. Neither belongs in your household bin or kerbside recycling, because lithium batteries can start fires in collection vehicles and waste centres.

• Used pods: take them to a vape-specific or small electrical drop-off point, a household waste recycling centre, or a retailer that offers take-back for vape products
• Devices: recycle through the same routes, and never put a device with a battery in general waste
• Packaging: cardboard and clean plastic wrapping can usually go in normal recycling where your local council accepts it
• Finding a drop-off: a postcode search on a national electrical recycling locator will show nearby options

Delivery: we deliver across the UK, and delivery options, cost and expected timings are shown at checkout and on our delivery information page. Because these are age-restricted goods, please make sure someone aged 18 or over can receive the parcel, and have photo ID available if asked. Check the box on arrival for damage, and the pack for the right flavour and strength.

Returns and faults: if a pod arrives faulty, damaged or not as described, your statutory rights under UK consumer law apply, and we will help you. Change-of-mind returns on opened inhalable products are normally not accepted for hygiene and safety reasons, while sealed, unopened items may be covered by our returns policy, so read that policy before ordering. Always keep your order number and the packaging until you have confirmed that everything is correct.
