SKE Crystal Nic Salts Hubbla Bubbla: what you are buying

SKE Crystal Nic Salts E Liquid Hubbla Bubbla is a nicotine salt e-liquid in a bubblegum flavour, sold as a refill bottle rather than a ready-made device. If you have used SKE Crystal disposables or prefilled pods before, this is the same flavour family in a form you pour into a refillable pod kit or a low-power tank. It suits people who want a sweet, easy-going, gum-style vape without paying device prices on every purchase.

Here is what to expect at a glance. Treat the strength and bottle-size lines as typical for this format and confirm them against the variation selector on the listing and the label on the bottle you receive, because the label always overrules a general description.

• Type: nicotine salt e-liquid for refillable devices, not a disposable.
• Flavour: Hubbla Bubbla, a sweet pink bubblegum profile.
• Bottle size: 10ml, which is the largest size UK rules allow for a bottle of nicotine e-liquid.
• Strength: choose from the options on the listing. UK rules cap nicotine e-liquid at 20mg/ml.
• Best used in: refillable pod kits and mouth-to-lung (MTL) devices with coils in the 0.8 to 1.2 ohm region.
• Not suitable for: sealed disposables or prefilled pods that cannot be opened and refilled.

The reason people reach for nic salts in the first place is the delivery. Salt-based nicotine is paired with an acid, which lowers the pH of the liquid and makes the throat hit noticeably softer than traditional freebase nicotine at the same strength. That means you can vape at 10mg or 20mg, the strengths most pod-style devices are built around, without the harshness you would get from freebase at those levels. For anyone moving away from cigarettes, that smoothness is a large part of why salts have become the default choice for small, low-wattage devices.

This page covers the flavour, the strengths, which devices and coils suit it, how to look after the battery in whatever you pair it with, how long a bottle lasts, how to fill and troubleshoot, what it costs to run, and how it stacks up against alternatives. We write this the way we would explain it across a shop counter: practical, specific and honest about the limits. Nicotine is addictive, and this product is intended for adult smokers and existing vapers only. If you do not currently smoke or vape, please do not start.

Flavour profile: what Hubbla Bubbla tastes like

Hubbla Bubbla is a bubblegum flavour. Think of the sweet, pink, slightly fruity gum you chewed as a kid rather than a mint chewing gum. The name is a spelling twist on a familiar confectionery brand, so a quick clarification: we describe the flavour style only, and this is an SKE e-liquid, not a product from any confectionery company.

Bubblegum e-liquids tend to follow a recognisable three-stage pattern, and that is a fair guide to what you will notice here:

• Inhale: a candy-sweet front end with a rounded, slightly fruity pink-gum character. There is usually a faint vanilla or strawberry-leaning softness behind it, which is how most makers recreate the chewy, sugary note of gum.
• Exhale: the sweetness carries through and becomes a little more creamy and gum-like. Expect a thick, sugary cloud flavour rather than a sharp or tangy finish.
• Aftertaste: a lingering sweetness on the tongue. It is pleasant for a few puffs and can get cloying if you vape continuously for a long stretch.

There is no cooling or menthol element in a straight bubblegum profile, so do not expect the icy kick you would get from the Ice flavours elsewhere in the SKE Crystal range. If you like your sweet flavours with a chill, a bubblegum-ice variant from another line is the better route. If you want pure, uncomplicated sweetness, this is the point of the flavour.

Two practical tips help here. First, give the coil time to saturate before you judge the taste, because a freshly primed coil with liquid still working into the wick will taste muted and slightly dry. Second, watch for what vapers call flavour fatigue. Sweet, single-note flavours are the most prone to it, where your palate stops registering the sweetness after a day or two and the liquid seems to have gone flat. The liquid has not changed. Rotating with a second flavour, or cleaning your palate with water between sessions, usually restores it.

Because the profile is sweet, it also tends to leave more residue on the coil than a mint or tobacco flavour would. That does not make it worse, but it is the main reason sweet liquids shorten coil life, which we cover in the coil and troubleshooting sections below.

Nic salts and choosing your nicotine strength

Strength is the single most important choice you make on this page, and getting it wrong is the commonest reason people end up disliking a perfectly good liquid. The short version: nic salts are a higher-strength, lower-harshness format, and you should pick your milligram number based on how much you smoked, not on what feels smoothest.

UK law caps nicotine e-liquid at 20mg/ml, which is 2% nicotine. That is the same ceiling that applies to disposable and prefilled-pod devices, so the top strength you will find in this format is 20mg. Nic salts are usually sold at 10mg and 20mg, and those are the figures to think about. Check the strengths actually offered on the listing, as availability can vary by flavour.

• 20mg/ml (2%): the usual starting point for people who have been smoking around ten or more cigarettes a day, or who want a cigarette-like hit from a small pod kit. At 20mg you will typically take fewer puffs per session and the bottle goes further.
• 10mg/ml (1%): better for lighter smokers, for people stepping down from 20mg, and for anyone who vapes frequently throughout the day and would rather take more puffs of a milder liquid. It is also the sensible choice if you are using a device that runs towards the higher end of the wattage range.

How do you know if you have picked wrongly? If the liquid is too strong you will notice lightheadedness, nausea, a racing feeling, hiccups or a harsh, scratchy throat even though it is a salt. If it is too weak, cravings return quickly, you find yourself chain-vaping, or you still reach for cigarettes after a few hours. Move one step either way and give it a couple of days before judging.

Device power matters too. The more wattage you push through a coil, the more vapour and the more nicotine per puff. A strength that feels right at 9W can feel much too strong at 15W. If you like to run your kit hot, lean towards 10mg. If you vape gently on a low-power pod, 20mg is usually fine.

A step-down plan is straightforward: once you have been off cigarettes for a few weeks on 20mg, switch to 10mg in the same flavour so the change is only in strength. Nic salts are not intended for non-smokers, young people, or anyone pregnant or breastfeeding, and anyone with a heart condition or other health concern should speak to a GP or stop-smoking service before relying on nicotine products.

Devices, coils and mesh: what to use it in

This is a refill bottle, so it needs a device that you can open and fill. The best matches are refillable pod kits and small mouth-to-lung systems that use coils with a resistance of roughly 0.8 to 1.2 ohm. Common refillable pod-system families such as Oxva Xlim, Vaporesso Xros and Smok Novo are examples of the sort of hardware people pair with nic salts, but always check your own device manual for refill instructions and coil compatibility before buying.

Understanding the coil is what separates a good experience from a bad one:

• Mesh coils: a flat mesh of heating material that spreads heat over a larger surface than a round wire. Mesh warms up quickly, gives a fuller flavour and handles a 50/50 style liquid comfortably. Resistances in the 0.6 to 1.0 ohm range are common in pod kits and suit 10mg to 20mg salts.
• Ceramic and cotton-wick coils: found in many pod cartridges. Ceramic can taste clean but sometimes feels slightly less punchy. Both are fine with nic salts provided the wick is fully saturated before you vape.
• Standard round-wire coils at 1.0 to 1.5 ohm: a better fit for the tightest MTL draw and the lowest wattages, giving a more restricted, cigarette-like pull.

As a rough guide, a 0.8 ohm mesh coil sits comfortably around 10 to 14W, a 1.0 ohm coil around 8 to 12W, and a 1.2 ohm coil around 6 to 10W. The printed range on the coil or in your manual is the authority. Starting at the bottom of that range and moving up only if the vapour feels thin is safer than starting high, because too much power is the usual cause of burnt tastes with a sweet liquid.

Do not put nic salts in a sub-ohm tank running at high wattage. A sub-ohm setup at 40W or more delivers huge volumes of vapour, and at 10mg to 20mg that translates into far more nicotine than is comfortable, with a harsh feel and a bottle that disappears in a day. Sub-ohm devices are designed for lower-strength freebase liquids, usually 3mg or 6mg.

Tank and pod capacity in UK devices is limited to 2ml, so a 10ml bottle fills a typical pod around five times. Airflow also matters. If your device lets you adjust it, tighten the airflow for a cigarette-style draw. Open airflow dilutes the flavour and makes salts feel thin.

Battery and charging: looking after the device you pair it with

The e-liquid itself has no battery, but the device it goes into does, and the battery is what decides how long a session lasts and how safe the setup is. Most refillable pod kits in this category use an internal rechargeable battery rated somewhere between about 400mAh and 1,000mAh, and charge over USB-C.

You can estimate real-world endurance with some simple arithmetic. A 1,000mAh lithium battery at a nominal 3.7V stores about 3.7 watt-hours. A three-second puff at 12W uses roughly 36 joules, which is about 0.01 watt-hours. Divide one by the other, allow for the efficiency losses in the chip, and you land in the region of 300 puffs per full charge. A smaller 500mAh kit would manage roughly half that at the same power, and dropping the wattage stretches the figure. These are estimates, not promises, but they are a better guide than guessing.

Charging sensibly protects both the battery and your home:

• Use the cable that came with the device, or a reputable USB-C cable, and a standard 5V wall or computer port. There is no benefit from fast chargers, and an unmatched high-output charger adds risk.
• Expect a charge to take around 60 to 90 minutes for a small pod kit. If your device has an indicator light, wait for it to confirm a full charge.
• Do not charge on a bed, sofa or other soft surface, and do not leave a device charging unattended overnight.
• Do not carry a device loose in a pocket or bag with coins, keys or other metal objects, which can short the battery.
• Stop using any device that is swollen, hot to the touch, leaking or damaged, and do not try to repair it.

Check the coil and pod before blaming the battery. A flat, burnt or dry taste is far more often a coil problem than a power problem. If the device is cutting out or the battery is no longer holding charge after a year or more of daily use, that is normal wear.

When a device reaches the end of its life, do not put it in the household bin. Vapes and their lithium batteries should be taken to a recycling point. Many retailers that sell vaping products accept used devices in store, and most council recycling centres take small electrical items under the WEEE scheme. Look for a drop-off point near you and remember that a battery in a bin lorry is a fire risk.

Performance: vapour, throat hit and how long a bottle lasts

In a properly matched pod kit, Hubbla Bubbla in nic salt form gives a moderate amount of vapour, a smooth throat hit and a flavour that comes through clearly on the first draw. This is not a cloud-chasing liquid. Nic salts are designed to deliver nicotine efficiently at low power, so the vapour production is modest compared with a large, high-VG sub-ohm setup, but the nicotine satisfaction per puff is high.

Throat hit is gentle at 10mg and firm but not harsh at 20mg. If you are used to cigarettes, 20mg will feel closer to the hit you know. If you are used to freebase liquids at 3mg or 6mg, 10mg salts will feel noticeably stronger even though the number looks small, because the acid in the salt changes how the nicotine registers in your throat.

Longevity is where a bottle comparison to a disposable becomes useful. A typical disposable holds around 2ml of liquid and is rated at about 600 puffs. A 10ml bottle contains five times that volume, so a rough equivalent is somewhere around 3,000 puffs of liquid, depending on your device and how you draw. That figure is an estimate rather than a lab number, since puff length, wattage and coil efficiency all change the real consumption.

• Light use (about 1ml a day): a bottle lasts around ten days.
• Moderate use (about 2ml a day): around five days, which is a full 2ml pod refilled once a day.
• Heavy use (3ml or more a day): two to three days, and a good sign that you may want to move up a strength so you are not chain-vaping.

A few habits stretch the bottle. Take slower, shorter pulls rather than long ones, avoid running the wattage at the top of the coil range, and keep the pod topped up so the wick never runs dry, since dry hits waste both liquid and coils. Keep the airflow tight, as an overly open draw makes you take more puffs to get the same satisfaction.

Flavour should be consistent from the first pod to the last in a bottle. If it fades over a few days, the cause is usually coil build-up or palate fatigue rather than the liquid itself.

Bottle, packaging and build quality

A refill bottle has no electronics, so build quality comes down to the bottle, the cap, the nozzle and the label. These matter more than people expect, because a badly designed bottle makes refilling messy and a loose cap is a safety problem in a house with children or pets.

The bottle for this format is a 10ml plastic dropper-style bottle with a narrow, long nozzle. The nozzle is the useful bit: it lets you reach into the small fill ports on pod kits without dripping down the side. Squeeze gently and steadily rather than hard, because 10ml bottles are soft and a firm squeeze sends a burst of liquid out of the tip.

Look for these points when your order arrives:

• Tamper-evident seal: the cap should have a ring that breaks when first opened. If the ring is already broken, do not use the bottle and contact us.
• Child-resistant cap: the cap should need a press-and-turn or similar action to open. Keep it fully closed whenever you are not filling.
• Label: the label should show the product name, nicotine strength, the health warning, ingredient information and a batch or lot reference. The strength on the label is what you rely on, so check it matches what you ordered.
• Bottle condition: no cracks, no sticky residue on the outside and no liquid inside the outer packaging.

E-liquid with nicotine is a poison risk if swallowed or spilled on skin, particularly for children and pets. Store bottles upright in a cool, dark place away from heat, direct sunlight and reach. A kitchen cupboard shelf or a drawer in a bedroom works better than a bathroom windowsill or a car glovebox. Stored well, nic salts keep their flavour and strength for a long time, and the liquid may darken slightly with age, which is normal for sweeter formulas.

If a spill gets on your skin, wash it off with soap and water. If it gets in your eyes, rinse with water and seek advice. For disposal, empty plastic bottles can go into recycling in some council areas but not others, so check your local council guidance before tossing them into the household recycling. Do not pour unused e-liquid down the drain.

How to fill, prime and use it

Filling a refillable pod takes a minute once you know the sequence. Follow your device manual first, since fill-port designs vary, then use this as a general method.

• Step 1, power off: make sure the device is switched off or unplugged from charging before you open it.
• Step 2, remove the pod or open the tank: pull the pod from the battery section and find the fill port. On many pods this is a rubber bung on the side or a sliding cover on top.
• Step 3, fill slowly: place the nozzle against the side of the port and squeeze gently, filling to just below the maximum line. Do not overfill, and do not cover the central airflow tube.
• Step 4, close the port: push the bung fully home or slide the cover shut.
• Step 5, wait: give a new coil five to ten minutes to soak, and a used coil two or three minutes. This single step prevents most burnt tastes.
• Step 6, first draws: take a few short, gentle pulls without pressing the button to draw liquid through, then start vaping normally at a low-to-mid wattage.

When using the device, keep draws to two to four seconds with a pause of 20 to 30 seconds between puffs. Chain-vaping heats the coil faster than the wick can resupply it and is the quickest route to a dry or burnt hit. If your device is draw-activated, do not hold the button down; if it is button-fired, release as soon as you stop drawing.

Keep the device upright when not in use and avoid leaving it in a warm car or beside a radiator, which thins the liquid and can lead to leaks. If you are switching flavours, rinse the pod with warm water, shake out the excess and let it dry fully before refilling, or the flavours will blend. If you plan to swap often, keep a second pod or tank for each flavour so you are never washing mid-day.

Wash your hands after filling, wipe any spilled liquid from the pod and bottle with a tissue, and put the bottle back out of reach. Never fill a pod near a heat source, and never vape in a car with young passengers or where the law or house rules prohibit it.

Troubleshooting: burnt hits, flat flavour, leaks and gurgling

Most problems with nic salts come down to a handful of causes, and almost all of them are fixable at home. Here is what to check when something feels off.

• Burnt or acrid taste: the coil is dry or worn. Prime it properly after each refill, drop the wattage, and slow down between puffs. A sweet liquid like bubblegum leaves residue quickly, so if the burnt taste persists after a refill, replace the coil.
• Flat or muted flavour: usually coil build-up or palate fatigue. Change the coil, wash the pod, and try a different flavour for a day. If the flavour was fine yesterday and not today, it is rarely the liquid.
• Gurgling or spitting: too much condensation or too much liquid around the coil. Dab the airflow channel with a tissue, avoid overfilling, and make sure the pod is seated properly.
• Leaking from the pod or battery: check the fill bung is fully closed, the pod is clicked in, and the liquid is not above the maximum line. Temperature swings and air pressure on flights can force liquid out, so keep devices empty or sealed when travelling.
• Too harsh in the throat: your strength may be too high for your wattage. Step down to 10mg, lower the power, or tighten the airflow.
• Too weak and unsatisfying: raise the strength, or check that the coil is not worn out. A tired coil produces less vapour and so delivers less nicotine.
• Dry hits with liquid still in the pod: the wick holes may be blocked or the liquid may be too thick for a cold environment. Warm the pod in your hands, wait a few minutes and try again.

Coil lifespan varies. With sweet liquids, many people replace a coil roughly every one to two weeks at moderate use. If you start to taste any burnt note, do not push through it. A new coil costs a few pounds and removes the problem.

If your device has stopped firing, check the battery, clean the contacts with a dry cotton bud and make sure the pod is correctly seated. If you suspect a faulty device, contact the retailer you bought it from. If you suspect a fault with the liquid itself, such as a damaged seal, wrong strength on the label or visible contamination, stop using the bottle and get in touch with us with the batch number.

Value for money and running costs

The honest case for refill e-liquid over disposables is about cost per millilitre and about waste. Because the bottle holds around five times what a typical 2ml disposable does, and because you are not paying for a battery, plastic shell and chip in every purchase, the running cost drops sharply once you own a reusable kit.

You can work out your real cost with three numbers. Cost per ml is the bottle price divided by 10. Daily cost is your cost per ml multiplied by the millilitres you use. Add the coil cost spread over the days each coil lasts. Here is an illustrative example using made-up round figures, not our prices: if a 10ml bottle cost £3, that is 30p per ml. At 2ml a day, you spend 60p a day on liquid. If a £3 coil lasts ten days, add 30p a day, giving about 90p a day in total. Compare that to the cost of a disposable that lasts a day or two for a few pounds each time and the gap becomes clear.

• Upfront cost: you need a refillable device. A decent entry pod kit is a one-off purchase that pays for itself within a few weeks if you were buying disposables daily.
• Ongoing cost: liquid, coils and occasionally a replacement pod.
• Waste: one device lasts months or years, whereas a disposable is a whole battery and plastic shell thrown away every few days.

Multibuy deals often apply across e-liquid ranges and can bring the per-bottle price down further. Check the listing and the basket for current offers rather than relying on a stated price here, since pricing changes. Buying a few bottles at once also makes sense once you have settled on a strength, because it saves repeat delivery and avoids running out.

Value is not only about price. A liquid that suits your device and strength, that you enjoy for the whole bottle and that does not burn through coils, is better value than a cheaper bottle you abandon half-used. If you are unsure about a flavour, start with one bottle instead of a bundle, and consider a rotation of two or three flavours to avoid palate fatigue.

How it compares with other options

Fair comparisons help you decide, so here is where Hubbla Bubbla in nic salt form sits against the alternatives you are likely to consider.

• Against SKE Crystal disposables and prefilled pods: the flavour family is shared, but a disposable is convenient, needs no filling and has no hardware to buy. The trade-off is cost per ml, battery waste and the fact that you cannot adjust anything. The refill bottle reverses all of that: it needs a device and a little effort, and you control strength, wattage and flavour rotation.
• Against other 10ml nic salt ranges: brands such as Elux, Aqua Salts and many others sell bubblegum-style flavours in the same 10ml format. Differences tend to be in how sweet the liquid is, how heavily it uses flavour concentrates, which strengths are offered, and the VG/PG balance. We list several of these on the site, and you may find one suits your palate better. There is no single winner, and personal taste is the deciding factor.
• Against freebase e-liquid and shortfills: freebase is smoother at low strengths and works well in sub-ohm kits for cloud production, but at higher nicotine levels it is harsh. Shortfills are 50ml or larger bottles meant to be mixed with nicotine shots. They offer a lower cost per ml for big, low-strength vapes but are the wrong tool for a small pod kit.
• Against tobacco and menthol salts: if sweet flavours cause palate fatigue for you, a tobacco or mint liquid is easier to live with all day. Many vapers keep one sweet flavour for treats and one neutral flavour as a daily driver.

Where Hubbla Bubbla is weaker is in complexity. Straight bubblegum is a one-note flavour by design. If you enjoy layered fruit blends or cooling finishes, you may find it too simple. Where it is strong is in familiarity and ease: it is a recognisable, uncomplicated sweet that suits people who do not want to work out a flavour.

UK rules on disposable devices have tightened in recent years, and refillable systems sit in a different category. If you are thinking about your longer-term setup, a refillable kit with bottled nic salts is the more flexible path, though you should always check the current legal position for any specific product you buy.

Who it is for, who should skip it, and UK delivery

Hubbla Bubbla nic salts are a good fit for adult smokers and existing vapers who already own, or are willing to buy, a refillable pod kit, who like sweet flavours and who want a lower running cost than disposables. They suit people who want a smooth throat hit at 10mg or 20mg without needing to think about sub-ohm coils or mixing nicotine shots.

You should probably skip this product if:

• You are under 18, or you do not currently smoke or vape. Nicotine is addictive and vaping is not recommended for non-smokers.
• You only own a sealed disposable or prefilled-pod device, which cannot be refilled.
• You use a high-powered sub-ohm kit and prefer low-strength freebase liquid.
• You dislike very sweet flavours, in which case a tobacco or menthol option is a better match.
• You are pregnant, breastfeeding, or have a medical condition that nicotine could affect. Speak to your GP or a stop-smoking service first.

On UK rules, nicotine e-liquid is limited to a maximum of 20mg/ml and a maximum bottle size of 10ml, and the product should carry the required health warning. It is an age-restricted product, so you must be 18 or over to buy, and carriers may ask for proof of age on delivery. Our stock is sourced through UK distributors, and the listing and checkout show the delivery options and any thresholds available at the time you order.

If you want to stop smoking altogether, NHS stop-smoking services and your local pharmacy can offer support and licensed nicotine replacement alongside or instead of vaping. Vaping is not risk-free, but for adult smokers who switch completely it is widely considered far less harmful than continuing to smoke.

Finally, think about the end of life of what you buy. Empty bottles should be disposed of in line with local council guidance, and old devices and batteries should be taken to a WEEE recycling point or a retailer drop-off, never put in household waste. Choosing a refillable setup already cuts the amount of electronic waste you produce, and responsible disposal closes the loop.
