Elux Nic Salts 20mg Blueberry: Overview

Elux Nic Salts 20mg Blueberry is a 10ml bottle of nicotine salt e-liquid made for refillable pod kits and other low-power mouth-to-lung devices. Elux built its name on disposable vapes, and the nic salt range takes the same flavour-first approach and puts it into a bottle you can use in a rechargeable kit. This listing is the blueberry flavour at 20mg/ml, which is 2% nicotine and the highest strength that can legally be sold in UK e-liquid.

Nicotine salt liquid differs from traditional freebase liquid in how the nicotine is formulated. A salt is made by pairing nicotine with an organic acid, commonly benzoic acid. That lowers the pH of the liquid and makes the vapour feel smoother at high strengths. Freebase nicotine at 20mg/ml would be harsh on the throat for almost everyone, while nic salt at the same strength is manageable in a small, low-wattage device. That is the whole reason this format exists, and it is why nic salts have become the usual choice for people who want a satisfying hit from a small pod kit.

Because this is an e-liquid and not a ready-to-use device, you need your own refillable kit to use it. This guide therefore covers the liquid itself and also what you need around it: compatible devices, battery and charging expectations, coils, wattage settings and troubleshooting. If you are stepping across from disposables, the later sections explain how to translate what you know about puffs into millilitres of liquid, because the maths is quite different.

• Product: Elux Nic Salts, Blueberry flavour
• Nicotine strength: 20mg/ml (2%), the UK maximum for e-liquid
• Bottle size: 10ml, the largest nicotine e-liquid bottle size allowed in the UK
• Nicotine type: nicotine salt, intended for pod kits and mouth-to-lung use
• Best suited to: adult smokers and existing vapers who want a fruit flavour with a firm nicotine hit

It is sold to adults aged 18 and over only. If you do not currently smoke or vape, a 20mg/ml product is not intended for you, and a lower strength or no nicotine at all would make more sense.

Flavour Profile: What Blueberry Actually Tastes Like

Blueberry is one of the most requested fruit flavours in UK vaping because it sits comfortably between sweet and tart. In a nic salt liquid the flavour is usually built around a ripe blueberry note, with a slightly jammy middle and a faint tart edge on the exhale. The aim is to taste like the fruit and not like a boiled sweet, and Elux leans towards the fruit side of that line.

On the inhale, expect a clean berry sweetness that arrives quickly. Nic salt liquids carry flavour well in small devices because the vapour is cooler and there is less throat irritation to compete with it. Mid-draw, the sweetness settles into a rounder, slightly deeper berry note, and on the exhale a little acidity shows up, which stops the flavour from feeling flat. There is no cooling agent in a plain blueberry liquid, so it is a warm, soft vape rather than an icy one. If you like menthol layered over fruit, you would look at the ice variants elsewhere in the range instead.

Flavour behaviour depends on the device. In a low-wattage pod kit around 8 to 12 watts, blueberry tends to taste fresher and more candy-like. Turn the power up on an adjustable kit and the sweetness deepens and starts to taste cooked, with the tart edge fading. Most people settle on a lower setting for this reason.

The elements you are likely to notice:

• Top note: bright, sweet blueberry on the inhale
• Middle: rounded berry with a mild jam-like quality
• Finish: light tartness, no menthol or cooling, a gentle sweet aftertaste
• Sweetness level: moderate to high, so coils will need a little more care than a dry tobacco liquid

If you tend to find single-fruit liquids a bit one-dimensional after a few days, vaping the same flavour all day can cause what is often called vaper's tongue, where the flavour seems to fade. Rotating with a second, quite different flavour such as a mint or a citrus liquid usually brings the taste back within a day or so.

Throat Hit and Nicotine Delivery at 20mg

The defining feature of this liquid is the combination of 20mg/ml strength and nicotine salt formulation. With freebase nicotine, the strength you feel is largely the strength in the bottle, and a throat hit rises sharply as you move up. With salts, the nicotine is absorbed more quickly and the throat sensation is softer, so a 20mg salt gives a noticeable, satisfying hit without the rawness of a 20mg freebase liquid.

For someone coming from cigarettes, the key is that nic salts deliver nicotine into the bloodstream faster than freebase. That is a large part of why many smokers find them more effective at reducing cigarette cravings. A few puffs are often enough to feel a response, and many users need fewer, shorter sessions across the day compared with lower-strength freebase.

Here is how the hit tends to feel in practice:

• Throat hit: medium to firm, smoother than freebase at a comparable strength
• Speed of delivery: quick; most users feel it within a few puffs
• Satisfaction per puff: high, which means you take fewer puffs overall
• Chain vaping: not recommended; at this strength it can bring on lightheadedness, nausea or a headache

The 50/50 split of propylene glycol and vegetable glycerine that is common in nic salt liquids helps the throat hit come through while keeping vapour production modest. Larger clouds are not the aim of this kind of liquid. If you want heavy vapour you would use a high-VG freebase liquid in a sub-ohm kit, which is a very different product. Check the bottle label for the exact PG and VG ratio of the batch you receive, as that is the definitive source.

If you find yourself feeling dizzy, sweaty or queasy after vaping, you have taken in more nicotine than your body wants. Stop, drink some water, and consider moving to a lower strength such as 10mg/ml. Nicotine tolerance varies a lot from person to person, and a strength that suits a heavy smoker will be too much for a light one.

Bottle, Packaging and Build Quality

Because this is an e-liquid, build quality comes down to the bottle, the cap, the label and the consistency of the liquid. The 10ml bottle is a standard plastic unit with a narrow dropper tip, and the cap is child-resistant, which is a legal requirement for nicotine liquids in the UK. The tip is shaped so it fits the fill ports on most pod kits, but some very narrow fill holes can be fiddly, so it is worth squeezing gently rather than pressing hard.

Look at the following on arrival:

• Tamper seal: the cap should have an intact ring or seal that breaks when you first open it
• Label: must show the nicotine strength, volume, ingredient list, health warning and a batch number
• Liquid colour: a pale to mid amber or straw tone is typical; blueberry flavours can appear slightly darker as they age
• Dropper tip: should be firmly attached and not leak when held upside down with the cap on

Squeezing the bottle should release a controlled drip. Nic salt liquids in a 50/50 base are thinner than thick high-VG liquids, so they flow easily. That is useful when filling small pods, but it also means a careless squeeze can overfill and flood a pod. Fill slowly and stop at the max fill line.

Plastic bottles of this type are not designed to be a long-term storage vessel once opened. Keep the cap tightly shut after each fill. Air and light degrade nicotine liquids and can darken the colour and change the taste over months. Store the bottle upright in a cool, dark place, away from direct sunlight, a radiator or a hot car.

Nicotine liquid is hazardous if swallowed or if it gets onto skin or into eyes in significant amounts. Always keep bottles out of reach of children and pets. Wash any spills off your skin with soap and water and wipe up surface spills straight away. The child-resistant cap is a safeguard but not a substitute for putting the bottle somewhere safe.

Devices, Batteries and Coils: Matching the Liquid to Your Kit

This product has no battery of its own, so the battery matters through the device you choose to put it in. Nic salts are designed for small, low-power kits, and the batteries in those kits are fairly modest compared with the large mods used for sub-ohm vaping.

Typical specifications for a pod kit that suits nic salts:

• Battery capacity: usually between 400mAh and 1000mAh in slim pen-style kits, and up to 1500mAh in larger ones
• Charging: USB-C on most current kits, and a full charge typically takes between 45 minutes and two hours
• Pod capacity: 2ml, which is the legal limit for tanks and pods in the UK
• Output: fixed or adjustable, commonly in the range of 8 to 25 watts

A 2ml pod with a 20mg/ml nic salt contains about 40mg of nicotine. A typical user will finish a pod in somewhere between several hours and a full day, depending on how often they vape. Battery life in a 600mAh kit usually lasts most of a day for a moderate user, but a heavy user may need a top-up charge midway.

Charging advice is straightforward. Use the cable that came with the kit, plug it into a normal USB adapter rated at 5V, and unplug the kit when the indicator shows it is full. Do not leave kits charging overnight on a soft surface such as a bed or sofa, and do not use a damaged cable. If a kit becomes hot, swollen or smells strange during charging, stop using it and take it to a recycling point.

Good matches include refillable pod systems with a screw-in or push-in cartridge, as well as small adjustable pod mods with a 0.6 to 1.2 ohm coil. Poor matches include sub-ohm tanks and high-wattage mods. At high power, 20mg/ml salt liquid is wasted quickly, tastes harsh and can deliver far more nicotine than you intend.

The disposable vape ban that took effect in Great Britain in June 2025 means single-use devices are no longer sold here. A rechargeable kit and a bottle of liquid is the route most former disposable users take, and it is also considerably less wasteful.

The coil is where the liquid becomes vapour, and the choice of coil changes how Elux Nic Salts 20mg Blueberry tastes and how long a bottle lasts. For a nic salt liquid like this one, the best results come from higher-resistance coils that run at low power.

Here are the common coil types you will meet:

• Standard round-wire coils (0.8 to 1.2 ohm): a classic design that gives a tight, warm vape. Good flavour at around 10 to 15 watts, with a firm draw that suits former smokers.
• Mesh coils (0.6 to 1.0 ohm): a flat sheet of mesh with a larger surface area. Mesh heats evenly, so it generally gives smoother, more consistent flavour and slightly more vapour. Most modern disposable-style pods use mesh, so people who switch from a disposable often find this feels familiar.
• Ceramic coils: a ceramic core with an embedded heating element. They hold flavour well but can be slower to prime and are more fragile.

Whichever coil you use, priming matters. Before the first puff on a new coil, put a few drops of liquid directly onto the coil's wicking holes and let the pod sit for five to ten minutes after filling. A dry-hit, which tastes burnt and sharp, is almost always the result of a coil that has not been given enough time to soak.

Nic salts can shorten coil life slightly when they are sweet, because sugars and sweeteners caramelise on the coil surface and form a residue. A sweet blueberry liquid will probably produce more gunk than a plain tobacco flavour. Expect a coil to last between one and two weeks for typical use, and change it as soon as the taste goes muted or burnt. Rinsing the pod occasionally with warm water, drying it completely and letting it air dry can extend its life, though a new coil restores flavour fully.

Do not push a coil beyond its rated wattage range. The range is usually printed on the coil's side. Staying within it protects the cotton, keeps flavour accurate and avoids using nicotine faster than necessary.

Nicotine Strength Guidance: Is 20mg Right for You?

Choosing a nicotine strength is the most consequential decision you make with a product like this. Too low, and you will keep vaping to chase satisfaction, which wastes liquid and can lead to going back to cigarettes. Too high, and you will feel unwell. A rough guide is below, though your own experience is the better judge.

• 20mg/ml: generally suited to people who smoke around 10 or more cigarettes a day, or who smoke within the first hour after waking. This is the strength this listing offers.
• 10mg/ml: suits lighter smokers, social smokers, or people who have already cut down and want to keep stepping down.
• 5mg/ml or lower: suits very light users or those close to quitting nicotine altogether.

Switching from cigarettes to vaping usually requires roughly equivalent nicotine at first, otherwise the cravings do not settle and it is easy to relapse. A common approach is to begin at 20mg/ml, use it for a few weeks until the urge to smoke has faded, and then move down to 10mg/ml and later lower. Many people find this tapering approach easier than stopping abruptly.

Signs the strength is too high include feeling light-headed, a pounding heart, nausea, a sore throat that does not ease, or needing to put the device down after only a few puffs. Signs it is too low include taking very frequent puffs, never feeling satisfied, or still reaching for cigarettes. Adjust in steps and give a new strength several days before deciding.

Remember that device choice shifts the effective dose. A warmer, higher-wattage setting produces more vapour per puff and therefore more nicotine per puff. If you move a 20mg liquid from a 10 watt kit to a 25 watt one, you may be taking in considerably more nicotine than you did before even though the bottle label has not changed.

This guidance is general information and not medical advice. Speak to a pharmacist, your GP or a local stop smoking service if you want personalised help. NHS stop smoking services in the UK offer free support and, in many areas, free vape starter kits to eligible smokers.

Who It Is For, and Who Should Skip It

Not every vaper needs a 20mg/ml fruit liquid. Here is an honest breakdown of who tends to get the most from this bottle and who should look at something else.

Good fit:

• Adult smokers who are changing from cigarettes and need a strong hit to settle cravings
• Former disposable users moving to a refillable pod kit who are used to a 20mg product
• People who like fruit flavours but want a berry that is not sour candy or cooling ice
• Vapers who prefer a small, discreet device and puff gently rather than producing huge clouds

Probably not for you:

• Anyone under 18, or any adult who has never smoked or vaped. Nicotine is addictive and this strength is not intended for people who have no nicotine dependence.
• Light smokers or occasional vapers, for whom 20mg/ml may feel overwhelming. A 10mg/ml bottle would suit them better.
• People who want large vapour clouds. Nic salts work with low power and do not suit sub-ohm tanks.
• Anyone who dislikes sweet liquids. This is a sweetened fruit flavour, and tobacco or menthol liquids would be a better match.
• Pregnant or breastfeeding women, people with heart conditions, and anyone on certain medications should talk to a healthcare professional before using nicotine products. NHS guidance generally recommends licensed nicotine replacement for pregnant smokers, though many specialists say vaping is safer than smoking if it helps someone stay off cigarettes.

For people who want to cut nicotine entirely, 20mg/ml is the opposite end of the scale from where you want to finish. Treat it as a starting point on the way down, not a permanent destination. Many vapers who keep using 20mg for years eventually find that their consumption creeps up and the cost with it.

If you are unsure, buy a 10mg/ml version first. It is easier to step up than to deal with the unpleasant effects of too much nicotine.

How to Fill and Use Elux Nic Salts

Using nic salt liquid is simple once you have done it a couple of times. Follow these steps for a clean, leak-free fill.

• Step 1: Switch the device off, or remove the pod from the battery. Filling a pod while it is attached can cause liquid to leak into the battery contacts.
• Step 2: Open the fill port. This is usually a small rubber plug on the side of the pod or a sliding cover on the base.
• Step 3: Shake the bottle gently, then twist off the cap and place the dropper tip into the fill port.
• Step 4: Squeeze slowly until the liquid reaches the max line. Avoid covering the central airflow tube, as liquid in the tube floods the coil.
• Step 5: Close the fill port fully and wipe off any liquid on the outside of the pod.
• Step 6: Let the pod stand upright for five to ten minutes so the wick can absorb liquid before the first puff.
• Step 7: Reattach the pod and start with a couple of gentle draws.

The best draw style for nic salts is mouth-to-lung. Draw into the mouth first for a second or two, then inhale. A slow, steady pull of three to five seconds works much better than a sharp short drag. Avoid taking long, deep, direct-to-lung inhales on a 20mg/ml salt, as the strength is designed for MTL use and will be unpleasant if inhaled too deeply.

If your device is adjustable, begin at the lowest suggested power and increase in one-watt steps until the flavour and warmth feel right. Many users end up at somewhere between 9 and 14 watts.

Do not mix this liquid with other liquids or add nicotine shots or flavour concentrates. It is formulated and labelled as a finished product, and mixing makes the final nicotine strength uncertain. Likewise, avoid topping up a partly used pod with a different flavour, as the leftovers will blend and may taste unpleasant.

If you need to switch flavours, empty the pod, rinse it with warm water, let it dry fully and then fill with the new liquid. A new coil gives the cleanest flavour change.

Troubleshooting Common Problems

Most problems with refillable kits come down to a handful of common causes. Work through the list before concluding that the liquid or the device is faulty.

• Burnt or harsh taste: usually the coil has not primed properly or has reached the end of its life. Re-prime with a few drops on the coil and wait ten minutes, or fit a new coil. Also check the pod is not nearly empty, since a low liquid level causes dry hits.
• Weak or muted flavour: often vaper's tongue or a worn coil. Try a different flavour for a day, and change the coil if the problem persists.
• Gurgling or spitting: the coil is flooded. Take the pod off, blow gently through the mouthpiece to clear the airflow, wipe the contacts and wait a few minutes. Avoid overfilling next time.
• Leaking: check the pod is properly seated, the fill plug is closed, and the pod is not cracked. Leaks also happen when a kit is stored on its side or travels in a warm pocket. Keep it upright when you can.
• No vapour: check the battery charge, check the pod is firmly connected, and check the airflow is not blocked. If the device has a draw sensor, a quick sharp puff may wake it.
• Throat feels sore or too harsh: turn the power down, shorten your puffs, or move to a lower nicotine strength.
• Sticky residue on the pod or contacts: wipe with a dry cloth or a cotton bud. Sweet liquids leave more residue than others.

If a new bottle tastes noticeably different from a previous one, check the batch number on the label. Minor batch-to-batch variation can happen with flavoured liquids, though it should be slight. If the liquid smells strange, has changed to a very dark colour or has an unpleasant chemical taste, do not use it. Contact the shop with your order number and a photo of the bottle label.

For battery faults such as overheating, swelling or failure to charge, stop using the device and follow the maker's advice. Do not attempt to open or repair lithium batteries yourself. Faulty or old kits should go to a battery or WEEE recycling point, not the household bin.

Value for Money and Longevity

A 10ml bottle of nic salt typically costs a few pounds, which makes it one of the cheaper ways to consume nicotine in the UK compared with cigarettes. The more useful way to look at value is cost per millilitre and how many millilitres you actually use each day.

Consumption varies a great deal. As an approximate guide for a 20mg/ml salt in a low-power pod kit:

• Light use: around 1ml a day, so a 10ml bottle lasts roughly a week and a half
• Moderate use: around 2ml a day, so a bottle lasts about five days
• Heavy use: 3ml or more a day, so a bottle lasts three days or so

For people moving from disposables, the comparison is helpful. A single-use vape carrying 2ml of liquid typically claims around 600 puffs. On that basis, 10ml of liquid is about five of those devices' worth of liquid, or roughly 3,000 puffs under similar use. A refillable setup reuses the battery and the kit, so it also avoids the repeated cost and waste of throwing away a battery every time the liquid runs out.

Costs beyond the bottle are the kit, which is a one-off purchase, and replacement coils or pods. Coil packs are inexpensive and each coil lasts a week or two. Over a month, a regular user typically spends noticeably less than they would on disposables, and a fraction of what a pack-a-day smoker spends on cigarettes. Check the current price per bottle on the page, as prices move, and compare on a per-ml basis when you look at other brands.

Shelf life is worth knowing about. Unopened and stored cool and dark, nic salt liquid generally stays in good condition for around 12 to 24 months. Once opened, aim to finish the bottle within a few months, as oxygen and light cause the nicotine to oxidise, which can darken the liquid and slightly change both flavour and strength.

Buying several bottles at once can reduce the per-unit cost and delivery charge, but only if you will use them in a sensible time. Do not stockpile more than you can use within a year.

How It Compares With Other Blueberry Nic Salts

Blueberry is a crowded category, so a fair comparison helps. Several UK brands make a nic salt blueberry, and each takes a slightly different approach.

• Elux Nic Salts Blueberry: a fairly straightforward ripe berry flavour with moderate sweetness and no cooling. The advantage is a recognisable, familiar profile and wide availability. The limitation is that it is not especially complex, so if you want layered flavours you may find it simple.
• Sour or blue razz variants from other brands: these mix blueberry with raspberry and sharper acids. They have more punch and more contrast, but the sharpness can feel rough on the tongue and some people tire of them quickly.
• Blueberry ice liquids: adding menthol gives a cold finish and a stronger throat feel. Good for people who want refreshment, less good if you want to taste the fruit itself.
• Premium craft nic salts: boutique brands sometimes offer more nuanced blueberry with cream, cake or yoghurt notes. They tend to cost more per bottle, and not everyone prefers a dessert style.
• Blueberry disposables: convenient and ready to use, but no longer sold in Great Britain since the 2025 ban, and a refillable setup with a bottle like this costs less over time.

In fairness, many competing 10ml nic salts at 20mg/ml are broadly similar in strength and formulation. The main differences are flavour tuning, bottle design and price. A bottle that suits one person's palate may feel too sweet or too thin to another's, and it is hard to judge from a description alone.

A sensible approach is to buy one bottle, try it for a few days, and decide before stocking up. If you like the brand's general flavour style, the rest of the Elux nic salt range is worth looking at, with other fruit options in the same family. Availability changes, so check the Elux category on the site for what is currently in stock.

This liquid is a good fit if you want a plain, reliable, fruit-forward blueberry. If you want something sharper, colder or more elaborate, one of the alternatives above may suit you better.

UK Rules, Safe Storage and Recycling

Vaping products in the UK are regulated, and the rules shape what you see on this page. Understanding them helps you buy and use the product responsibly.

• Nicotine cap: e-liquids and disposables sold in the UK cannot exceed 20mg/ml nicotine. This bottle sits exactly at that limit.
• Bottle size: nicotine e-liquid bottles are limited to 10ml, and refillable tanks and pods to 2ml.
• Age restriction: products must not be sold to anyone under 18, and adults must not buy them on behalf of under-18s.
• Labelling: bottles carry a nicotine health warning, an ingredient list and child-resistant, tamper-evident closures.
• Product notification: sellers must have notified products to the Medicines and Healthcare products Regulatory Agency before sale.

For storage, keep bottles and kits away from children and pets, out of direct sunlight, and away from extremes of temperature. Never leave a vape device in a hot car, since lithium batteries and heat do not mix. Keep spare coils and pods in a sealed container to stop dust and moisture getting in.

Recycling is an important responsibility. Empty plastic bottles can usually go in your household plastic recycling after being rinsed and emptied of liquid, but check your council's guidance for what is accepted locally, because rules differ between areas. Remove or separate the cap if your council asks for this. Vape devices and batteries must never go in household bins, general recycling or on the street. They contain lithium-ion batteries that can catch fire in refuse vehicles and recycling plants.

Take old kits, spent batteries and electrical parts to a WEEE drop-off point. Shops that sell vape devices are legally required to take back used devices and batteries, and many council recycling centres have dedicated battery and small electrical collection bins. Pods and coils can often be taken in too if the shop accepts them; if not, check with your local recycling centre.

Choosing a rechargeable kit with a bottled liquid already cuts down on waste significantly compared with single-use devices, and responsible disposal of the parts that do wear out keeps that benefit intact.
