Elux Nic Salts 20mg Double Apple: overview

Elux Nic Salts 20mg Double Apple is a 10ml nicotine salt e-liquid built around a pairing of red and green apple. It comes in the standard UK bottle size at 20mg/ml, the highest nicotine strength British rules allow for a refill liquid, and it is made for low-powered pod kits and mouth-to-lung (MTL) or restricted direct-to-lung (RDL) devices rather than high-wattage sub-ohm tanks.

Elux is a name most UK adult vapers know from its disposable devices. The Nic Salts range takes the same flavour-first approach and puts it in a bottle you can use in a refillable kit. That matters more than it used to. Single-use disposable vapes have been illegal to sell across the UK since 1 June 2025, so anyone who liked the grab-and-go convenience now needs a rechargeable pod kit or pen and a bottle of liquid to go with it. A 20mg nicotine salt is a close match to the nicotine delivery and throat feel that disposable users were used to, which is why bottles like this one have become a routine purchase for people who are switching over.

Double Apple is a plain, honest fruit flavour. There is no cooling blend, cream layer or dessert note stacked on top of it. The profile is two apple characters working together: one sharp and green, one sweeter and rounder. If you want a liquid that tastes of apple rather than of a sweet shop, that simplicity is the whole point.

The sections below cover how it tastes, what the numbers on the label mean, which devices suit it, how to fill and use it, what to check when something goes wrong, and how it compares with other nicotine salt ranges. We have tried to be straight about who it suits and who is better off with something else.

Nicotine is addictive. This product is for adults aged 18 or over who currently smoke or vape. It is not for non-smokers, under-18s, or anyone who is pregnant or breastfeeding.

Flavour profile: what Double Apple actually tastes like

Double apple has a long history in flavoured shisha tobacco, where it is usually built from red and green apple and, in some traditional versions, a faint aromatic edge. In vaping the name has loosened into a general description for a sweet and tart apple blend. Elux's version leans towards the fruit rather than the heritage, so expect a clear apple flavour from the first puff. Flavour is subjective and varies a little between batches, but this is what most people report.

• Green apple skin: a crisp, slightly sharp note on the inhale that gives the liquid its freshness.
• Red apple flesh: a rounder, juicier sweetness that sits in the middle of the puff.
• Light candy sweetness: a boiled-sweet style sugar note, present but not syrupy.
• Soft tart finish: a brief sour tingle on the exhale that stops the sweetness lingering too long.
• Faint aromatic lift: a very light floral or herbal nuance that some vapers link to the shisha origins of the flavour name.
• Clean aftertaste: no heavy cream, no menthol residue, so your palate resets between puffs.

How the flavour behaves depends on how hot your coil runs. At the low end of your device's power range, the green apple tartness is more prominent and the whole thing tastes lighter and crisper. Turn the power up and the sweetness comes forward, the red apple turns more candied, and the finish gets warmer. Most people settle somewhere in the middle. If a puff tastes sugary and flat, drop the wattage a little before you decide you do not like the liquid.

A word on flavour fatigue. Single-note fruit flavours are easy to vape all day, but after a week or two of the same liquid your taste buds can stop registering it, and you may think the flavour has faded when it has not. If that happens, switch to something different for a day or two. A menthol or a berry blend is enough to reset things. Apple flavours also pair well with ice or cooling profiles if you want variety, though this particular bottle has no cooling agent in it.

If you are choosing between apple liquids, a rough guide is this: apple ice adds menthol and is cold; sour apple pushes the tartness much harder; apple and pear is softer and more mellow. Double Apple sits in the middle ground, sweet enough to be easy and tart enough not to be boring.

Specifications and what the label tells you

Here are the headline figures for Elux Nic Salts 20mg Double Apple. Always check the label on the bottle you receive, as that is the legal source of truth for your batch.

• Brand and range: Elux, Nic Salts
• Flavour: Double Apple (red and green apple)
• Bottle size: 10ml, which is the largest size permitted for nicotine-containing e-liquid in the UK
• Nicotine strength: 20mg/ml (2%), the UK maximum
• Nicotine type: nicotine salt, which is smoother than freebase nicotine at the same strength
• VG/PG balance: a balanced 50VG/50PG blend is typical for this style of liquid, so confirm the ratio printed on your bottle
• Packaging: small plastic bottle with a narrow nozzle, tamper-evident ring and child-resistant cap
• Intended devices: refillable pod kits and low-wattage MTL or RDL devices
• Not intended for: sub-ohm tanks running 40W and above, or any prefilled device you are not meant to refill
• Age restriction: 18+

It is worth knowing how to read the rest of the label. UK-supplied e-liquid must carry a nicotine addiction warning, an ingredients list, the nicotine strength in mg/ml, a batch number and a best-before date. The bottle should also have a child-resistant, tamper-evident closure. Products sold in the UK must be notified to the regulator before they go on sale, which is one reason you should buy from a UK retailer rather than an unknown overseas marketplace. If a bottle arrives without a proper label, with a broken seal or in a larger-than-10ml container with nicotine in it, do not use it and contact the seller.

You will notice the nicotine strength is shown as a figure in mg/ml. That is milligrams of nicotine per millilitre of liquid. A 10ml bottle at 20mg/ml contains a total of 200mg of nicotine, which sounds like a lot but is spread across several days of use and is absorbed only in small fractions with each puff.

Nicotine strength guidance: is 20mg right for you?

The 20mg/ml figure is both the strongest and the most common strength for nicotine salts in the UK. It is a ceiling set by law, not a recommendation for everyone. Whether it suits you depends on how much you smoked, how quickly you take puffs, and what kind of device you use.

Nicotine salts are formulated with a small amount of acid, which lowers the pH of the liquid. In practice this means the nicotine feels smoother in the throat than the same strength of freebase nicotine, and it tends to be absorbed more quickly. So a 20mg salt hits differently from a 20mg freebase: softer on the way down, but with a more immediate effect on cravings. This is why salts have become the default choice for small pod devices where you take short, gentle puffs.

As a rough guide, many adult smokers find the following starting points reasonable.

• Smoking 10 or more cigarettes a day: 20mg is a sensible place to begin, in a low-powered device.
• Smoking fewer than 10 a day, or already vaping at 10 to 12mg: try a lower strength first. If this flavour is not offered in a lower strength, take shorter puffs and use a lower wattage.
• Coming from disposables: most disposables were already at 20mg, so this strength will feel familiar.
• Social or occasional use: 20mg is usually more than you need. Consider a lower strength.

Signs that your nicotine is too high include dizziness, nausea, headaches, a racing heart or feeling jittery. If this happens, stop vaping, get some fresh air and drink water. Signs that it is too low include constant cravings, chain-vaping and falling back on cigarettes. Do not respond to cravings by pushing the wattage up on a 20mg salt, as that delivers a lot of nicotine very quickly and the throat hit becomes harsh.

For reference, UK rules cap e-liquid nicotine at 20mg/ml, limit refill bottles to 10ml and limit tank or pod capacity to 2ml. These are the same limits that applied to disposable vapes before the ban, so if you used a disposable you were already vaping at the 20mg ceiling. A 10ml bottle therefore fills a typical 2ml pod about five times.

If you are trying to cut down gradually, the sensible route is to step down to the next lower strength rather than using the same strength less often with bigger puffs. Speak to a local stop-smoking service if you want support. Many offer free advice and, in some areas, free vape starter kits.

Throat hit, vapour and everyday performance

The balanced VG/PG blend typical of this range gives Elux Nic Salts a middle-of-the-road feel. PG carries flavour and produces the throat hit; VG produces vapour and smoothness. With the two in roughly equal parts you get a clear flavour, a moderate throat hit and a modest amount of vapour. This is not a cloud-chasing liquid, and it is not meant to be.

• Throat hit: noticeable at 20mg but smooth, usually described as a gentle tap rather than a scratch. Salts at this strength feel milder than freebase at 12 to 18mg.
• Vapour production: small to moderate. You will see a light cloud on exhale, which is useful for discreet use.
• Flavour intensity: strong per puff, because low-power devices burn less liquid and the flavour is more concentrated in each draw.
• Wicking: a 50/50 liquid is thin enough to soak into the cotton or mesh of small pod coils quickly, which reduces the chance of dry hits at low power.
• Consistency: flavour should stay steady through the bottle. If it fades fast, check the coil first.

Think about puff style when you assess performance. Salt nicotine is designed for short, tight draws, typically two to three seconds, with the vapour held in the mouth briefly before inhaling for MTL, or drawn a little more loosely on RDL pods. Long, deep pulls at high power waste liquid, taste harsh and deliver more nicotine than you probably want.

You can expect a fairly smooth ramp-up of flavour. The first puff after the coil has been idle for a while may taste a bit muted; the second and third are fuller. Heavy use over a few minutes can warm the pod and make the liquid thinner and the flavour sweeter, which is normal. If you are chain-vaping at 20mg you will feel the nicotine climbing quickly, so pace yourself.

In terms of real-world consumption, a rough planning figure for low-power pod use is somewhere between 1,500 and 2,500 puffs from a 10ml bottle, depending on puff length, device power and how hard you draw. Treat that as a ballpark, not a promise. Higher wattage can halve it.

Compatible devices, coils and mesh technology

The best way to get a good result from this liquid is to match it to the right kind of hardware. Elux Nic Salts is designed for refillable pod systems with coil resistances between roughly 0.8 and 1.2 ohm, running at about 8 to 15 watts. Some RDL pods at 0.6 ohm also work, but at the lower end of their power range.

• Refillable pod kits: the natural home for nic salts. Popular examples of this type include the Vaporesso XROS, OXVA Xlim, GeekVape Wenax and SMOK Novo families. Check your own device's manual for its supported coil range.
• Mesh coils: a flat or cylindrical mesh has a large surface area that heats evenly, which brings out the flavour more fully and reduces hot spots. They also tend to last a little longer than basic cotton-wrapped wire coils, though sweet liquids still shorten their lifespan.
• Ceramic coils: found in some pods. They are clean-tasting, but can be slow to wick thicker liquids and may give a weaker flavour with lower-VG blends.
• Standard wire and cotton coils: usually 1.0 to 1.2 ohm and fine for MTL use. Prime them well before the first puff.

What to avoid: sub-ohm tanks with coils of 0.15 to 0.4 ohm running at 40W or more. They will use through a 10ml bottle of 20mg salts quickly, give a harsh throat hit and deliver far more nicotine than the liquid is designed for. They are also hard to enjoy with a 50/50 liquid because you will notice the lack of vapour smoothness at high power.

Do not try to refill a disposable or a closed pod that is not designed for it. Doing so can damage the device, cause leaks and is a safety risk. If the device does not have a visible fill port, it is not made to be refilled.

Coil life matters with fruit flavours. Sweeteners in e-liquid can build up on the coil as a brown residue, known as gunk, which dulls the flavour and eventually makes it taste burnt. For a sweet apple liquid like this, a coil may last somewhere between one and two weeks of regular use. Replace the coil as soon as the flavour turns flat or scorched, rather than pushing the power up to compensate.

Battery, charging and power settings

This is a liquid, so it has no battery of its own. The battery question belongs to the device you put it in, and it affects how the liquid performs more than most people realise.

Most pod kits use a single lithium-ion or lithium-polymer cell with a nominal voltage of 3.7V and a capacity of anywhere from about 400mAh to 1,000mAh or more. A 1,000mAh cell holds about 3.7Wh of energy. At 10W, that is roughly 22 minutes of actual firing time. At three seconds a puff, that comes to somewhere over 400 puffs, before you allow for efficiency losses. For many people that is a day of moderate use or a little more. Smaller 400 to 500mAh devices will need topping up more often.

• Charging: use the USB-C cable that came with the device and a standard 5V charger, ideally 1A to 2A. Avoid cheap unbranded chargers.
• Do not leave charging unattended: particularly overnight or on soft furnishings.
• Temperature: do not charge or store a device in a hot car, in direct sunlight, or in freezing conditions.
• Damaged batteries: if the device swells, smells odd, gets very hot or the casing is cracked, stop using it and recycle it safely.
• Pass-through use: avoid vaping while charging if your device allows it. It generates extra heat.

Power settings are the other half of the picture. Running a 20mg salt at too high a wattage is the single most common reason people find it unpleasant. If your device has adjustable power, start at the low end of the coil's recommended range, which is printed on the coil itself, and work upwards in small steps. Many people settle at 10 to 12 watts for a 1.0 ohm mesh coil. Lower power also extends battery life, so there is a practical benefit as well.

When a battery or vape device reaches the end of its life, do not throw it in the household bin. Vapes contain lithium cells and electronics, so they count as waste electrical equipment and belong in a proper collection point. Many vape shops and larger retailers will take old devices back, and local council recycling centres have designated drop-off bins for small electricals. Take your old pod kit there, and remove any e-liquid first.

Bottle design, packaging and build quality

With a liquid, build quality comes down to the bottle, the closure and the label. Most Elux Nic Salts bottles are small, squeezable plastic bottles with a long, narrow nozzle that fits the fill ports of most pod devices. Check the one you receive, but this is the general arrangement and it is the one that suits pod filling best.

• Child-resistant cap: required by UK rules. You usually need to push down and turn at the same time, which can take a minute to get used to.
• Tamper-evident ring: a plastic band that breaks when you first open the bottle. If it is already broken, do not use the liquid.
• Squeezable body: gives you control over how much liquid you dispense. Squeeze gently; too much force can force liquid out in a rush and flood the pod.
• Narrow nozzle: lets you target the small fill port of a pod without spilling.
• Label: carries the flavour name, strength, volume, nicotine warning, batch number and best-before date. Keep the box or take a photo of the label in case you need to contact the retailer.

Storage matters more than the bottle itself. Keep the liquid upright, in a cool, dry place out of direct sunlight, and well away from children and pets. Heat and light degrade e-liquid, and a bottle left on a windowsill will go dark and lose flavour much faster than one kept in a drawer. Nic salts naturally darken a little with age, going from clear to a pale amber. That is cosmetic and does not mean the liquid has gone bad, but if the flavour tastes off or the colour has changed dramatically, replace it.

Most sealed e-liquid is good for roughly one to two years from manufacture if stored sensibly. Check the best-before date when you buy and when you open it.

When the bottle is empty, rinse it out if your local council accepts plastic bottles with residue, and put it in the plastic recycling according to local rules. Cardboard outer packaging goes in the paper and card recycling. Never put nicotine bottles into the bin with liquid still inside, and never pour nicotine liquid down a drain.

Who it suits, and who should skip it

Nicotine salts at this strength are for a specific group of people. Being honest about that group is better than pretending it fits everyone.

Elux Nic Salts 20mg Double Apple is a good fit if you are:

• An adult smoker who wants to move to vaping and was previously a heavy or regular cigarette user.
• A former disposable user who needs a refillable alternative with similar nicotine strength and a familiar fruit flavour.
• A pod-kit owner looking for a straightforward fruit flavour that you can vape through the day without it becoming sickly.
• Someone who prefers apple, pear or other crisp orchard fruit flavours over sweets, drinks or desserts.
• A vaper who wants a discreet cloud and a smooth throat hit, rather than lots of vapour.

You should skip it, or look at something else, if you are:

• Under 18. It is illegal to sell nicotine products to anyone under 18, and a retailer may ask for age verification.
• A non-smoker. There is no reason to start using nicotine. If you want an apple flavour without nicotine, look at nicotine-free liquids instead.
• Pregnant or breastfeeding, or living with a heart condition, without having spoken to your GP or pharmacist first.
• A sub-ohm user who wants dense clouds at 50W and above. This is a poor match for that style.
• Sensitive to nicotine, or already vaping at 3 to 6mg. Twenty milligrams will feel far too strong.
• Someone who dislikes tart fruit. The green apple edge is not subtle, so a purely sweet flavour will suit you better.
• After a menthol, ice or dessert profile. This is not that.

If you are a smoker who is thinking about switching, remember that the aim is to stop smoking cigarettes. Local stop-smoking services can offer behavioural support, and combining that with a suitable nicotine product improves your chances.

How to fill and use it

Using nic salts in a pod kit is simple, but a little care avoids most of the common problems like leaks, flooded coils and burnt hits. Follow these steps, which apply to most refillable pods.

• Step 1, wash and dry your hands: skin contact with nicotine liquid is best avoided. Wipe up any spills straight away.
• Step 2, switch the device off: remove the pod from the battery if it detaches.
• Step 3, open the fill port: most pods have a silicone plug on the side or underneath. Pull or slide it open.
• Step 4, open the bottle: push the child-resistant cap down and turn it. Keep it away from children.
• Step 5, fill the pod: insert the nozzle into the port and squeeze gently, stopping just below the max line. Do not touch the central airway tube or fill it with liquid.
• Step 6, close the port: make sure the plug is fully seated and wipe any spilled liquid from the outside of the pod.
• Step 7, prime the coil: wait five to ten minutes, with the pod upright, so the cotton can saturate. Skipping this is the number one cause of a burnt first coil.
• Step 8, take a few dry draws: with the device off, draw gently on the mouthpiece a few times to pull liquid into the coil.
• Step 9, start low: power on at the low end of the range and take two or three short puffs. Adjust from there.

As you vape, keep the pod upright between sessions and carry it in a pocket or case with the mouthpiece protected. Refill when the liquid level falls to about a quarter, since vaping on an empty or near-empty pod is another route to a dry hit. A new coil takes a couple of refills to settle, and the flavour usually improves after the first pod.

Take your time with the first few puffs. If you are used to disposables, a refillable kit may feel slightly different in the draw and the vapour, and a lower wattage often feels more like the disposable you are used to. Wipe the mouthpiece now and again. Keep spare coils on hand so a worn one never stops you vaping and sends you back to cigarettes.

Troubleshooting common problems

Most problems with nic salts come down to the coil, the power setting or how the pod was filled. These are the ones we hear about most, and what to do.

• Burnt or scorched taste: usually a worn coil, a coil that was not primed, or power set too high. Replace the coil, wait the full priming time and reduce the wattage.
• Weak or muted flavour: check for flavour fatigue first by switching liquid for a day. If it is not that, the coil is probably gunked up and needs replacing.
• Gurgling or spitting: too much liquid in the airway. Remove the pod, blow gently through the mouthpiece to clear it, and wipe it dry. Fill a little lower next time.
• Leaking from the pod: check the fill plug is fully seated, that the pod is not cracked, and that you have not overfilled. Heat and changes in pressure on a flight can also push liquid out.
• Dry hit, hot and harsh: the pod is running low or the coil is not saturated. Refill, prime and try again at a lower power.
• Throat hit too harsh: the combination of 20mg and high wattage. Lower the power, take shorter puffs, or move to a lower strength.
• Device not firing: check the battery charge, then the connection between pod and battery. Clean the contacts with a dry cotton bud.
• Cap is hard to open: push down firmly while turning. If it still will not move, ask another adult for help rather than forcing it.
• Crystals around the cap: dried residue from spillage. Wipe with a damp cloth. It does not mean the liquid is spoiled.
• Liquid has darkened: a slight amber colour is normal for nicotine salts, but a very dark, cloudy or smelly liquid should be replaced.

If none of this fixes the problem, test the pod and battery with a different liquid to find out whether the fault is with the device or the e-liquid. This takes a few minutes and saves you a lot of guessing. If you suspect the bottle itself is faulty, keep it, note the batch number and contact us with a photo.

Value for money and how it compares

Judging value on an e-liquid means looking at cost per millilitre and then at how long a bottle lasts in your hands. A 10ml bottle at moderate low-power use might last somewhere between four and ten days. A heavy user may go through it in three or four. Divide the current price on this page by ten to get the cost per millilitre, and multiply by your daily use to see what it costs per day.

Against disposables, which are no longer sold legally in the UK, a refillable pod kit and nic salts tends to work out cheaper over a month. You pay once for the kit, then for liquid and the occasional coil. Many UK retailers also offer multi-buy deals on salts, which can bring the per-bottle price down if you know the flavour suits you.

Here is how Elux Nic Salts compares with other widely sold salt ranges. These are general observations, not rankings, and tastes differ.

• IVG Salt and Nasty Salt: both are well known 10ml, 20mg ranges with a wide flavour choice. Nasty Salt is often described as sweeter and more dessert-leaning, and IVG tends to have a broader menu of mixes. If you want a more complex fruit or drink flavour, these are worth a look.
• Hayati Pro Max Salts and Elfliq: ranges that follow the disposable flavour trend with ice and candy blends. If you want those heavier mixes, they are closer to what you want than a plain apple.
• Dinner Lady Salts: a more layered, premium-leaning range that often costs a little more. The extra complexity is a real difference if you are happy to pay for it.
• Pod Salt: a long-running salt brand that is popular with people who like simpler, easy-drinking flavours, so it is a fair like-for-like alternative to a plain apple.

Where does Elux fit? It sits in the middle of the market. The flavours are recognisable and uncomplicated, the strength is the familiar 20mg, and the bottle format is the same as everyone else's. It does not try to out-engineer the competition on complexity, and some competitors will beat it on layered flavours or nuance. What it does well is give you a straightforward apple that most people can enjoy without having to think about it.

Its weaknesses are worth stating. There is no ice or cooling option in this bottle, so if you like your fruit cold you will need a different flavour. And at 20mg it leaves less room for strength adjustment than a range that stocks 5, 10 and 20mg. Check the product page for the strengths on offer.

In short, it represents reasonable value if you want a plain apple salt at the UK maximum strength, and you are using a low-power pod kit. If you want something more elaborate, or a lower nicotine level, there are better fits elsewhere.
