Pod Salt Nexus 10mg Mr Blue at a glance

Pod Salt Nexus 10mg Mr Blue is a 10ml nicotine salt e-liquid made for refillable pod kits and other low-power, mouth-to-lung devices. It comes in a 10mg/ml strength (1% nicotine), which sits at the gentler end of the UK range and is the usual starting point for people who want a smoother hit than a 20mg salt gives. Mr Blue is a blue-fruit flavour with a sweet, slightly tart berry character and a light cool finish, and this listing is the updated '(New)' version within the Nexus line.

This guide is written for UK vapers who want to know what they are buying before they order. We cover flavour, throat hit, which devices suit it, how to choose between nicotine strengths, how to fill and prime a pod, what to do when something goes wrong and how it compares with other 10ml nic salts. Where we give figures, such as puff estimates or suggested wattage, they are working estimates based on how nicotine salts behave in typical pod kits rather than manufacturer claims, so treat them as guidance, not guarantees.

Key specifications

• Age restriction: sold to adults aged 18 and over only

Where Pod Salt Nexus fits and what '(New)' means

Pod Salt built its reputation on 10ml nicotine salts made for refillable pod kits, and the Nexus line continues in that format. It is aimed at vapers who have moved on from disposables, or who never wanted them, and now fill a pod kit by hand. Since the UK ban on single-use disposable vapes came into force on 1 June 2025, bottled salts like this have become the obvious route for people who still want a small, pocketable and low-effort way to vape without throwing away a battery every few days.

The '(New)' tag in the product title marks the updated release of the Mr Blue flavour inside the Nexus range. Brands change artwork, batch coding or minor recipe details between releases, so if you have bought an earlier Mr Blue bottle you may notice small differences in the label layout or in how sweet or cool the liquid feels. We list it under the current name so you can match it to what you see on the box and bottle.

A short explanation of nicotine salts helps here, because it explains why this product behaves differently from a 3mg or 6mg freebase bottle. Nicotine salt e-liquid uses nicotine bound to an acid, most often benzoic acid, which lowers the pH of the liquid. That makes the vapour noticeably smoother at higher strengths and lets nicotine reach the bloodstream a little faster than freebase does. In practice a 10mg salt can feel satisfying to someone who smoked a moderate number of cigarettes a day, even though 10mg sounds low next to the 12mg or 18mg figures on freebase bottles. Do not compare salt and freebase strengths directly, because the same milligram number does not feel the same.

Salts are meant for low-power devices. Drop one into a sub-ohm tank running at 60 watts and you get a lot of vapour, a lot of nicotine and very little pleasure. Nexus Mr Blue is intended for the small refillable pod kits sold in UK vape shops, typically running at around 8 to 15 watts, which is where a salt behaves the way it should.

UK rules shape the product too. Nicotine e-liquid is sold in bottles of no more than 10ml, the maximum strength is 20mg/ml, bottles carry child-resistant and tamper-evident closures, and the packaging shows health warnings. Pod and tank capacity is capped at 2ml. Products are also notified to the MHRA before they can be sold. That is why 10ml bottles in 10mg and 20mg are the norm across the whole nic salt category, not just this brand.

Flavour profile: what Mr Blue tastes like

Mr Blue belongs to the blue-fruit family, a category that mixes berry sweetness with a tart edge and usually a hint of candy. Flavour descriptions are subjective and Pod Salt keeps the exact recipe to itself, so what follows is what vapers commonly report picking up rather than an official ingredient list.

On the inhale the dominant note is sweet blue berry fruit, closer to a blue raspberry sweet than to a freshly picked blueberry. A slightly tart edge stops the sweetness feeling heavy, much like the sharpness in a boiled sweet. At 10mg and low wattage the inhale is soft and rounded rather than sharp.

On the exhale the sweetness lingers and a light cooling effect appears. Think of a mild chill rather than a strong blast of menthol. If you dislike heavy menthol this is the kind of coolness that sits in the background. If you want an intense icy hit, look for a dedicated ice variant instead, because Mr Blue is not positioned as an ice flavour.

The aftertaste is clean and fruity with a faint sugary residue on the lips. It does not leave a creamy or dessert-like coating, which suits people who vape through the day and do not want their mouth to feel coated by lunchtime.

How the flavour changes with the way you vape:

• Lower wattage (8 to 10W): softer fruit, more sweetness, less tart edge and a cooler vapour
• Mid wattage (11 to 14W): fuller flavour, the tart note becomes clearer and throat hit rises slightly
• Higher wattage: tends to flatten delicate berry notes and can make the liquid taste burnt or harsh, so it is not recommended with a salt
• Fresh coil: the cleanest, brightest flavour, while a tired coil dulls blue-fruit flavours quickly

Two practical points. First, sweet fruit liquids put more sugar-based residue on the coil than unsweetened or tobacco liquids, so expect to change coils a little more often. Second, vaping a single sweet flavour all day can lead to flavour fatigue, where the taste seems to fade even though nothing has changed. If that happens, keep a second bottle in a different style, such as a tobacco or menthol, and alternate for a day or two. The flavour usually comes back.

Performance, throat hit and nicotine delivery

For an e-liquid, performance means three things: how it feels in the throat, how well it delivers nicotine, and how many puffs you get from a bottle. At 10mg/ml in a salt form, Mr Blue is built for a smooth but noticeable draw. The throat hit is light to medium, noticeably softer than a 20mg salt and more present than a low-strength freebase. Most people describe it as comfortable enough to take long draws without coughing, which is the main reason 10mg is such a common choice.

Nicotine delivery from salts is quicker than from freebase, so the satisfaction arrives sooner after the first few puffs. A typical session of ten to fifteen draws leaves many ex-smokers feeling settled for a while. If you find yourself reaching for the device every few minutes, the strength may be too low for your habit, and the section on strength below will help you decide.

Vapour production on a pod kit is modest by design. Do not expect the dense clouds of a sub-ohm tank. A 50/50-style base tends to carry flavour well and produce a reasonable, not excessive, amount of vapour, and that suits indoor and public use where discretion matters.

Estimated puffs per bottle. Real figures depend on your device, wattage and draw length, but a useful rule of thumb for pod kits is that 1ml of liquid gives about 200 to 300 puffs. On that basis:

• A 2ml pod holds around 400 to 600 puffs, or a full day for many light to moderate users
• A full 10ml bottle is roughly five pod fills, so around 2,000 to 3,000 puffs in total
• Each 2ml pod contains about 20mg of nicotine at this strength, because 2ml at 10mg/ml equals 20mg
• Heavy, long draws at higher wattage can use a pod much faster, while short draws at low wattage stretch it further

It is worth comparing that with the old throwaway format. A disposable vape held 2ml of 20mg liquid, so you were buying roughly 40mg of nicotine in a sealed unit with a battery you could not replace. A bottle of Nexus 10mg gives you around 100mg of nicotine in liquid form at a strength you choose, with a device you keep. The per-puff cost is usually lower and there is far less electronic waste.

Bottle design and build quality

Since the product is a liquid, build quality comes down to the bottle, the closure and the labelling. Nexus is supplied in a 10ml plastic bottle with a narrow nozzle designed to fit the fill ports on common refillable pods. It is a squeezable bottle, so you can control the flow with gentle pressure instead of pouring. A good fill nozzle matters more than it sounds, because fill ports on small pod kits are tiny and a wide nozzle spills liquid over the pod and your fingers.

What to check when your bottle arrives:

• Tamper-evident ring: the cap should be sealed with a ring that breaks on first opening. If it is already broken, do not use the bottle and contact us.
• Child-resistant cap: UK rules require this, so you will need to press down and twist or squeeze and turn. Keep the cap fitted when the bottle is not in use.
• Label information: nicotine strength (10mg/ml), the flavour name, a batch code, a best-before date, the ingredient list and the required health warning should all be present and legible.
• Nozzle: it should be intact with no cracks and a clean opening.

The Mr Blue colour-coded label makes it easy to tell flavours apart if you keep several bottles. We suggest writing the date you opened the bottle on the label with a marker pen, so that you can keep track of how long it has been in use.

Storage matters. Keep the bottle upright, capped, out of direct sunlight and away from heat sources such as radiators and car dashboards. Heat and light break down flavour compounds and can darken the liquid over time, which is a normal sign of ageing in nicotine liquids but also a hint that flavour will be duller. Stored properly, nic salt liquid generally keeps its character for around a year or two, but always follow the best-before date on your bottle.

Keep nicotine liquid out of reach of children and pets. Nicotine is toxic if swallowed or if it gets on the skin in quantity, so wash your hands after filling and wipe up any spills straight away. If liquid contacts your skin, rinse with water and soap, and seek medical advice if you feel unwell.

Matching it to a device: battery and charging

Nexus Mr Blue has no battery of its own, because it is a refill liquid, but the battery in your pod kit has a direct effect on how the liquid performs. A device with a stable, regulated output gives consistent flavour from the first puff of a charge to the last. Pod kits suited to 10mg salts typically have batteries of around 400mAh at the small end up to about 1,000mAh for larger refillable kits. As a rule of thumb, a 500 to 800mAh battery running at 10 to 12 watts will last a day or so for a moderate vaper before needing a top-up.

Things to consider when pairing this liquid with a device:

• Output mode: many modern pod kits are draw-activated with fixed output, which works well with salts. If your kit has adjustable wattage, start at the low end and work up in small steps.
• Pod capacity: UK law caps tanks and pods at 2ml, so every refillable pod you buy will be 2ml or less.
• Fill port: check that the nozzle fits. Most standard pods use a silicone bung or a side slide that works with narrow-tip bottles.
• Battery health: if flavour fades even with a fresh coil, a failing battery may be delivering lower power than it should.

Charging sensibly. Use the cable supplied with the device or a reputable USB-C cable, and a standard 5V charger or a computer port. Avoid cheap unbranded chargers and never use a fast-charge brick if the device is not designed for it. Charge on a hard, non-flammable surface, do not leave a charging device unattended overnight, and stop using any device that gets hot, swells, smells odd or shows a damaged casing.

Disposal and recycling. Vape devices contain lithium batteries and should never go in household bins or kerbside recycling, because crushed batteries have started fires in refuse lorries and waste plants. Take old pod kits to a household waste recycling centre or to a retailer that offers vape take-back. Many UK shops provide this service, and it is free to use. The empty 10ml bottle can usually go in general waste once it is fully empty, though you should check your local council guidance because rules differ by area.

Coils, wicking and pod compatibility

The coil is where the liquid becomes vapour, and the right coil makes a significant difference to how a 10mg salt tastes and feels. Nicotine salts do best with higher-resistance coils that run at low power. Suitable coils for Nexus Mr Blue fall broadly into three groups:

• Mesh coils at 0.6 to 0.8 ohm: a flat mesh surface heats evenly and gives fuller flavour and slightly more vapour. These suit 10 to 15 watts and are common in modern pod kits.
• Regular wire coils at 0.8 to 1.2 ohm: the traditional choice for mouth-to-lung pod vaping. They run cooler at 8 to 12 watts and give a tighter draw with a firmer throat hit.
• Ceramic coils: found in some pods, they offer clean flavour and a long life, though they can take a little longer to prime and sometimes feel slightly muted with very sweet liquids.

Pods in the same class as popular refillable systems from brands such as Vaporesso, SMOK, Uwell and Geekvape generally handle a 50/50-style salt without trouble. Always check the manufacturer's coil recommendations for your own device, because the exact resistance and wattage range differ between models.

Wicking and priming. New coils are packed dry, and if you vape one before the cotton has soaked up liquid you will burn the wick and ruin the coil. After filling, give the pod at least three to five minutes to saturate. With a thick or sweet liquid, a couple of extra minutes does no harm. Take a few gentle draws without pressing the button, if your device allows it, to pull liquid into the wick before the first firing.

Coil life with this flavour. A sweet blue-fruit liquid is harder on coils than a plain tobacco, because sugars and flavouring compounds caramelise on the heating surface. Expect a coil to last somewhere between one and two weeks of regular use, which is a bit shorter than for unsweetened liquids. Signs of a coil nearing its end include flat flavour, a faintly burnt taste, a gurgling sound and a rough throat hit even when the pod is full. Replace it rather than trying to push on, since a burnt coil is unpleasant and wastes liquid.

Do not use this liquid in sub-ohm tanks below 0.5 ohm, or at wattages above about 20. At those settings a 10mg salt delivers more nicotine per puff than most people want, and the flavour often turns harsh.

Choosing the right nicotine strength

Strength is the decision that most affects comfort. Nicotine strength is measured in milligrams per millilitre. At 10mg/ml this bottle is 1% nicotine. The UK limit for nicotine-containing e-liquid is 20mg/ml, and the same cap applies to any disposable or pod product. That means 10mg sits in the middle of the usual nic salt range, which runs from about 5mg up to 20mg.

As a rough guide that many UK vape shops use, and not as medical advice:

• Light smokers or occasional vapers (up to about 10 cigarettes a day): 10mg is usually a sensible starting point and may even feel strong at first.
• Moderate smokers (about 10 to 20 a day): 10mg can work if you vape often through the day, though many people in this group start on 20mg and step down later.
• Heavy smokers (20 or more a day): 20mg is often needed at the start, and 10mg is better treated as a step-down strength.
• Former smokers who vape for habit or flavour: 10mg or lower is usually enough, and a lower strength gives you more room to enjoy the flavour without overdoing it.

Signs the strength is too high: dizziness, nausea, a racing heart, headaches, hiccups or a harsh, scratchy throat. If you notice these, stop, take a break, and move to a lower strength or take fewer, shorter draws.

Signs it is too low: constant cravings, chain-vaping, taking very long draws and feeling unsatisfied after a session. Moving up in strength is usually better than vaping more often, as heavy use at a low strength wears through liquid and coils faster.

Many vapers use a step-down approach, moving from 20mg to 10mg and eventually to lower strengths or none. Some keep two bottles on the go, with 10mg for daytime and a slightly stronger option for times when cravings are worse. If you plan to quit nicotine entirely, speak to a local stop smoking service or pharmacist, who can offer free support and combine vaping with other aids.

One firm point: nicotine is addictive, and vaping is for adults who already smoke or use nicotine. If you do not currently smoke or vape, this product is not for you, and it should never be used by anyone under 18.

Who Nexus Mr Blue 10mg suits, and who should look elsewhere

No single liquid suits everyone, so it helps to be honest about who benefits most from this one.

It is a good fit if you:

• Smoke or vape lightly to moderately and want a smooth throat hit that does not catch
• Already own a refillable pod kit running at low to moderate power
• Like sweet, cool-finish berry flavours rather than tobacco, dessert or heavy menthol
• Have switched from a disposable and want to cut running costs and waste
• Want a 10ml bottle that fits in a pocket and works with most small pod systems

You might prefer something else if you:

• Are a heavy smoker who needs 20mg to avoid cravings, in which case the 20mg version of the same range is a better match
• Use a sub-ohm tank or a high-wattage mod, where a 50/50 salt will taste harsh and a freebase shortfill is the better choice
• Dislike sweet liquids or find fruit flavours cloying after a few days
• Want a dense, cloud-heavy vape, which small pod kits are not designed for
• Do not currently smoke or vape. Nicotine products are not recommended for non-smokers, and this is not a product for them

Who should speak to a professional first. If you are pregnant, breastfeeding, have a heart condition, high blood pressure, diabetes, or take regular medication, talk to your GP or pharmacist before using nicotine products. We are a retailer, not a clinician, and nothing here is medical advice.

For smokers trying to stop, the evidence in the UK has been that vaping can help some adults move away from cigarettes, and the NHS offers support alongside it. That is a reason to use a product like this as a replacement for smoking, not as an addition to it. Dual use, where you smoke and vape together, keeps most of the harm of smoking in place.

If you are unsure which camp you fall into, the simplest approach is to buy one 10mg bottle and one 20mg bottle of the same flavour, try the lower strength first and see how a few days go. Because Nexus follows the same flavour recipe across strengths, you can move up or down without having to learn a new taste.

How to fill, prime and vape it

Filling a pod takes a minute once you have done it a few times. Follow these steps for a clean fill and good flavour.

• Step 1, prepare: wash and dry your hands, switch the device off or remove the pod, and place a tissue under your work area.
• Step 2, open the fill port: pull back the silicone bung or slide open the fill cover. Do not force it, as these parts are small and can tear.
• Step 3, fill gently: insert the nozzle into the port and squeeze slowly. Stop at the fill line or when the liquid is a few millimetres below the top. Do not overfill, because liquid forced into the central air tube will flood the coil and leak.
• Step 4, close and wipe: push the bung back flush, close the cover and wipe the pod with a tissue so no liquid is left on the mouthpiece or the contacts.
• Step 5, wait: let the pod stand for three to five minutes so the wick saturates. Skipping this is the most common cause of a burnt first coil.
• Step 6, start gently: take two or three short, soft draws, then use it as normal.

How to draw. Nicotine salts are designed for a mouth-to-lung draw: take the vapour into your mouth first, pause for a second, then inhale into the lungs. Slow, steady draws of two to four seconds give a clean flavour and keep the throat hit comfortable. Hard, fast pulls make the vapour hotter, increase nicotine intake and can cause coughing.

Pacing yourself. Take fewer, shorter sessions rather than one long one. Nicotine from salts arrives quickly, so a few draws may be enough. If you feel light-headed, stop and wait for it to pass.

Everyday care. Keep the pod upright when you can, top up once the liquid is about a third full rather than letting the coil run dry, and wipe the mouthpiece now and then. When the flavour starts to fade or you hear gurgling, swap the coil. Keep the device out of heat and out of reach of children, and travel with the pod empty or the device switched off, so that a button press in a bag does not fire it.

Troubleshooting common problems

Most problems with pod vaping have simple causes. Here are the ones we hear about most often with salts like Nexus Mr Blue, and what usually fixes them.

• Burnt or harsh taste: usually a dry or worn coil. Make sure the pod has had three to five minutes to soak after filling, avoid chain-vaping, and replace the coil if the taste has not cleared after a fresh fill.
• Weak or flat flavour: often a tired coil, but it can also be flavour fatigue after several days on the same sweet liquid. Change the coil, then try a different flavour for a day.
• Leaking from the pod or mouthpiece: normally caused by overfilling, a poorly seated bung, or a cracked pod. Fill only to the line, press the bung in flush and wipe the pod. If it still leaks, replace the pod.
• Gurgling or spitting: condensation or flooded airflow. Blow gently back through the mouthpiece to clear it, or wipe it out with a tissue. A coil that gurgles all the time is nearing the end of its life.
• Dry hits (little vapour, hot draw): the wick is not getting liquid quickly enough. Refill when the pod is about a third full, prime properly and avoid very long draws. A slightly lower wattage often helps.
• Throat feels rough: the strength may be too high for you, the draw too hard, or the wattage too high. Try shorter, gentler draws or a lower strength.
• Device will not fire: check the battery charge and that the pod is seated firmly. Clean the contacts on the pod and device with a dry cotton bud. If the light flashes, consult your device manual because the pattern shows its fault code.
• Liquid seems thick in cold weather: allow it to come to room temperature and wait a little longer before vaping. Do not heat the bottle.
• Nausea or dizziness: stop, drink water and rest. These are signs of too much nicotine and call for lower strength or fewer draws.

If you have tried these fixes and still have an issue, check the batch code and date on the bottle and get in touch with us. A bottle that is damaged on arrival, has a broken tamper seal or smells or looks different from normal should not be used. We will arrange a replacement or refund under our returns policy.

Value for money and how it compares with alternatives

Value is not just the sticker price. It is the cost per puff, the number of coils you use, and how much of the liquid you actually enjoy. Priced as a single 10ml bottle at 10mg, Nexus Mr Blue sits in the standard range for branded nic salts in the UK, and multi-buy offers on bottles tend to bring the effective price down further. Our listing shows the current price and any bundle deal.

On the numbers above, a bottle gives roughly 2,000 to 3,000 puffs, which is around five pod fills. Even allowing for a coil change every week or two, that works out noticeably cheaper per puff than a disposable of equivalent puff count, and it leaves you with a device you can reuse. If you vape all day, the cost of coils is a real part of the picture, so factor in roughly one coil for every two to four bottles.

Honest comparisons. Plenty of other 10ml nic salts compete in this space, and several are worth a look depending on your taste:

• Elf Liq and Hayati Pro Max Salts: both come in 10ml bottles with 10mg and 20mg options and wide flavour lists. Their blue-fruit recipes lean in different directions, with some sweeter and some more tart. If you like a bolder, sweeter profile, they are worth trying.
• IVG Salt and Nasty Salt: well-known names with large ranges. Some vapers find the flavours more complex or more dessert-focused, while others prefer the cleaner, lighter finish of Nexus.
• Bar Juice 5000 and similar: aimed at the same pod-kit audience with a distinct house style. Prices vary by flavour and retailer.

These products share the same basic format, so the choice comes down to flavour preference, price on the day and which brand your local shop stocks. We would not claim Nexus tastes better than every rival, because taste is personal. Where it does well is in being a soft, approachable blue-fruit option at a mid-range strength with a familiar bottle and widely available stock.

Trade-offs to bear in mind. A salt costs more per millilitre than a basic freebase shortfill, and it is no use in a sub-ohm tank. If you run a high-power device you will get better value from a larger freebase bottle. For small pod kits, however, a 10ml salt is the practical and economical choice.

Finally, think about waste. Refilling a reusable device and recycling the electronics responsibly is lower impact than buying and discarding a sealed disposable, which is another reason many UK vapers have switched.
