Solo Bar 30K Prefilled Pod Kit Blue Sour Raspberry / Mr Blue: what you are buying

The Solo Bar 30K Prefilled Pod Kit in Blue Sour Raspberry / Mr Blue is a rechargeable nicotine salt vape kit built around prefilled pods. The battery body is reusable, and the pods arrive already filled at the factory, so there is no bottle to open, no coil to fit and no tank to assemble. On this site it is listed at £10 and offered in two strengths, 10mg and 20mg.

Two flavour names sit in the title, Blue Sour Raspberry and Mr Blue. Our reading of the listing is that the kit pairs these two profiles, which is why the name carries a slash. Check the contents when it arrives so you know exactly how many pods are in the box, because pod count decides how long the kit lasts more than any headline figure does.

The format exists because the UK market changed. Single-use vapes stopped being legal to sell in June 2025, and since then the shelf has filled up with rechargeable bars and kits that can be topped up or have their pods swapped. A prefilled pod kit keeps the simplicity people liked about disposables while letting you recharge the battery and replace the part that wears out.

Here is the kit at a glance. Some figures are the manufacturer's ratings or typical values for this class of device rather than anything we have measured on a bench, and we have said so where that applies.

• Brand: Solo Bar
• Format: rechargeable battery body with prefilled pods
• Rated puffs: 30,000 (manufacturer rating, treat as a ceiling)
• Nicotine: nicotine salt, 10mg or 20mg per ml
• Coil: mesh coil built into each pod
• Activation: draw activated, so there is no button to hold
• Charging: rechargeable lithium-ion battery, usually via USB-C in this class
• Price on this site: £10

Everything below is written for adults who already smoke or vape. If you have never used nicotine, this is not a product to start with. Nicotine is addictive, and the sale of vapes to anyone under 18 is illegal in the UK.

Performance and puff delivery

The headline number is 30,000 puffs, and it is worth being straight about what that means. A puff rating is a manufacturer's estimate, usually worked out from the amount of e-liquid in the device and an assumed amount used per puff. It is not a guarantee, and it is not measured against your habits. Think of 30,000 as a ceiling reached under favourable conditions, not a promise about how many draws you will get.

UK rules matter here. The Tobacco and Related Products Regulations 2016 limit the capacity of a pod or tank to 2ml of e-liquid, and nicotine strength to 20mg per ml. A single pod can therefore only hold so much, which is why the sensible way to judge longevity is to count the pods in the kit and think about how often you vape. As a rough guide, many adults using a 2ml nicotine salt pod find it lasts somewhere between one and four days, depending on how much they vape and how long each draw is.

What you can expect in use is more predictable than the puff count:

• Draw-activated firing. You inhale and the device fires. Short, gentle draws give cooler, more flavourful vapour. Long, hard draws heat the coil harder and use liquid faster.
• A firm, restricted draw. Nicotine salt devices in this class are built for a mouth-to-lung style, closer to drawing on a cigarette than to the open airflow of a big sub-ohm tank.
• Consistent output for most of a pod. Vapour and flavour should stay steady until the pod runs low. As the wick runs dry, expect thinner vapour and a toasted note, which is your cue to swap pods.
• Modest vapour volume. This is a throat-hit-and-flavour device, not a cloud device. If you want large clouds, you are shopping in a different category.

Throat hit depends on nicotine strength more than anything. The 20mg version gives a noticeable kick at the back of the throat, similar to a cigarette, while the 10mg version is softer. Both use nicotine salts, which are smoother than the freebase nicotine used in older tank devices at the same milligram level.

The practical test of performance is simple. If the device fires every time you draw, tastes the same on the second day as on the first, and does not leak, it is doing its job. The rest of this guide covers how to keep it that way and what to do when it does not.

Flavour profile: Blue Sour Raspberry and Mr Blue

Flavour is the reason to pick a kit like this, so it deserves a proper description rather than a list of adjectives.

Blue Sour Raspberry sits in the sweet-shop corner of the market. Blue raspberry is a confectionery flavour rather than a fresh-fruit one, a bright, sugary berry note with a slightly tangy edge that is nearer to a boiled sweet or a fizzy drink than to a punnet of raspberries. The word sour in the name points to an added tartness on the exhale, a mouth-watering finish that stops the sweetness feeling heavy. People who like sherbet, sour sweets or blue slush drinks tend to enjoy this profile.

Mr Blue is a brand-style name rather than a named fruit, and the exact recipe is not published. In this category the name normally signals a blue-fruit mix, with blueberry doing most of the work. Expect a rounded, sweet berry flavour, often with a faint cooling finish. If you like blueberry muffin or blueberry candy notes more than sharp ones, this is the milder of the two.

A few points help set expectations:

• Both are sweet. Neither is a tobacco or a menthol-led flavour. If you are moving away from cigarettes and want something that tastes nothing like them, that is an advantage. If you want a tobacco taste, look elsewhere in our range.
• Sour reads stronger at 20mg. Tartness and throat hit stack up, so the sour profile can feel sharper in the stronger version. If you find it harsh, the 10mg is the smoother route.
• Flavour fades gently over a pod. The first third tastes clearest. Towards the end the sweetness drops and a slightly flat or toasted note can creep in as the liquid level falls.
• Sweet flavours coat the coil. Sugar-based flavourings caramelise over time, so a pod can taste slightly different on day three than on day one. This is normal and part of why pods are replaced rather than refilled.

The wider Solo Bar 30K range carries many combinations. Slugs in our catalogue include Pineapple Ice Lemon Lime, Strawberry Ice Watermelon Ice, Red Apple Ice Cherry Ice and Kiwi Passionfruit Guava Strawberry Kiwi, so if two blue profiles are too similar for you, a fruit-and-ice combination is the obvious alternative. Many buyers pair one sweet kit with one cooler, sharper kit to avoid flavour fatigue.

Design and build quality

At this price point, build quality means practical details rather than premium materials. A £10 pod kit is a plastic-bodied, pocketable device, and the question is whether it is put together tidily, rather than whether it feels like a luxury object.

Here is what to look at when it arrives:

• Body and finish. Devices in this class usually have a lightweight moulded housing in a coloured or gradient finish. Run a thumb over the seams. They should be even, without gaps or rough edges.
• Pod seating. Prefilled pods click or push into the battery body, sometimes with a magnetic or spring-loaded connection. A pod that is seated properly sits flush and does not rattle. A pod that wobbles may have a dirty or misaligned contact.
• Mouthpiece. A flat or slightly tapered drip-tip style mouthpiece is typical. It should feel comfortable and smooth on the lips, with no burrs from the moulding.
• Airflow and charging port. The air intake is normally on the body or the base of the pod and should be clear. The charging port sits at the bottom, and a good fit between plug and socket is a sign of decent assembly.
• Size and weight. Pod kits are slimmer and lighter than the big sealed bars, which makes them easier to carry in a pocket or small bag.

The weak point of almost every device in this price bracket is the seal between pod and body. If the device is carried in a warm pocket, with the mouthpiece down, or is tossed into a bag full of loose items, it can weep a little liquid into the airflow channel. Keep it upright when you can, put the mouthpiece cap back on if one is supplied, and avoid leaving it in a hot car or on a radiator.

Pods are consumables and are not designed to be opened. You should not try to pry them apart, refill them with other liquid or modify the device. That is partly a safety point and partly practical: the prefilled design relies on a sealed liquid path, and tampering invites leaks and electrical faults.

In short, the design is functional and aimed at people who want to open the box, seat a pod and start. It does not pretend to be more than it is, and for a kit priced at £10 that is a fair standard to hold it to.

Battery and charging

The battery is a rechargeable lithium-ion cell sealed inside the body. The listing does not give a milliamp-hour figure we can verify, so we will not state one as fact. Pod kits of this size and style usually carry a cell somewhere in the 500mAh to 1,000mAh range, and a cell in that bracket powering a low-wattage mesh coil should last from a couple of days to about a week of moderate use between charges.

That reasoning follows from how the device works. A nicotine salt mesh coil draws modest power, typically in the region of 10 to 15 watts, so a cell of that capacity delivers a good number of draws before it needs topping up. Heavier use shortens the interval, and so does vaping in cold weather, because lithium-ion cells deliver less in the cold.

Charging notes worth following:

• Use the right cable and a sensible source. A USB-C cable and a standard phone charger or computer port will do. Avoid very high-output fast chargers where you can, and never use a cable that is frayed, bent or hot to the touch.
• Expect roughly one to two hours for a full charge. A small cell charges quickly. If an indicator light is fitted, it normally changes colour or switches off when the cell is full.
• Do not charge it overnight and out of sight. Charge it on a hard, non-flammable surface where you can see it, not under a pillow or on a sofa cushion, and unplug it when it is done.
• Avoid vaping while it charges. Some devices allow it, but it puts extra heat and load on the cell and is not recommended.
• Do not charge a hot or swollen device. If the body looks puffed up, smells strange or is too hot to hold, stop using it and take it to a recycling point.

The battery will usually outlive a single pod, so you will charge the device several times over the life of the kit. Lithium-ion cells lose capacity gradually, and after a few months of regular charging you may notice shorter intervals between charges. That is normal ageing, not a fault.

Lithium batteries must never go in household rubbish or kerbside recycling. Where they end up is covered in the recycling notes near the end of this guide.

Mesh coil technology and the prefilled pod system

The coil inside each pod is a mesh coil. Rather than a thin wire wound into a spiral, a mesh coil is a flat or curved sheet of fine metal mesh with a large surface area. The cotton wick presses against it, and when you draw, the whole sheet heats at once.

That construction has three practical effects:

• More even heating. The liquid is vaporised across a wide surface instead of at a few hot points, which helps reduce the burnt taste that can come from overheating one spot.
• Cleaner flavour. Even heating tends to give a clearer, more consistent taste, which matters for a sweet-and-sour profile where you want the tartness to come through without scorching.
• Faster ramp-up. Mesh reaches working temperature quickly, so vapour starts almost as soon as you begin to draw.

Resistance for this kind of coil is typically in the region of 0.6 to 1.2 ohms, matched to a modest battery. The exact figure is not published for this kit, so treat that range as a description of the class rather than a spec sheet.

Nicotine salt e-liquid in pods of this kind is usually a 50/50 or similar mix of propylene glycol and vegetable glycerine. A balanced ratio carries flavour and throat hit while keeping the liquid thin enough to wick through the cotton at a modest temperature. The listing does not state the ratio, so again this describes the category, not a verified figure.

The prefilled approach has a clear logic. The coil and the liquid arrive as a matched pair, so you do not have to guess how long to let a new coil soak or how much to put in the tank. When the pod is finished, the coil is finished too, and you fit a new one. That is why the system tends to give a consistent first draw and reduces the coil-priming errors that cause dry hits in refillable tanks.

Two cautions apply. First, pods are not universal. A pod made for one kit will not necessarily fit another, so check that replacement pods match your device before you buy. Second, a new pod should be left to settle for a few minutes after fitting so the cotton can saturate. Firing a dry coil is what burns it, and it cannot be undone.

Nicotine strength guidance: 10mg or 20mg

This kit is listed in two strengths, 10mg and 20mg. The UK legal maximum for vape e-liquid is 20mg per ml, which is 2 percent, so the 20mg option is the highest strength any UK retailer can legally sell. The same cap applies to prefilled devices, and it is the figure you will see on every compliant product on the shelf.

Choosing between the two comes down to how much nicotine you currently take in and how the device delivers it. Nicotine salt formulations are absorbed more quickly and feel smoother than freebase at the same strength, which means a 20mg salt device can feel stronger at the throat than people expect but is easier to inhale than the old high-strength freebase juices.

These are sensible starting points, not rules:

• 20mg: suits people who smoke around ten or more cigarettes a day, or who smoked heavily until recently and are switching fully. It provides a satisfying throat hit and helps keep cravings down without needing to vape constantly.
• 10mg: suits lighter smokers, people who have already cut down, existing vapers stepping down from 20mg, and people who prefer a softer draw. It will also tend to last longer because you are not chain vaping to meet a nicotine need.

Signs that your strength is not right are fairly clear. Too high shows up as nausea, a racing heart, dizziness, a headache or a harsh feeling in the throat. Too low shows up as lingering cravings, vaping much more often than you expected, and still reaching for cigarettes. If you feel unwell, stop and wait for it to pass, then try the lower strength.

If your aim is to quit nicotine altogether, stepping down is a reasonable plan. Many people move from 20mg to 10mg, then to a lower strength, over a period of weeks or months. NHS stop smoking services offer free support, and speaking to a pharmacist or GP is worthwhile if you are pregnant, have a heart condition or take regular medication.

None of this is medical advice. It is practical guidance for adults who already use nicotine. Nicotine is addictive, and a vape is not a harmless product, only a lower-risk alternative to smoking for people who would otherwise carry on with cigarettes.

Who this kit is for, and who should skip it

A product page that sells to everybody is not much use, so here is a plain description of the buyer this kit suits and the ones it does not.

It is a reasonable fit if you:

• Currently smoke, or vape already, and want a simple, tidy way to carry on without cigarettes.
• Do not want to buy bottles, mix liquid or fiddle with coils, and prefer a device you can pick up and use.
• Like sweet and sour fruit flavours, and would enjoy having two different profiles in one kit.
• Want a low-cost entry point to the prefilled pod format and are happy to learn how a pod system behaves before spending more.
• Are happy with a mouth-to-lung draw similar to a cigarette, rather than a big, airy lung inhale.

It is probably not for you if you:

• Have never smoked or used nicotine. There is no benefit to starting, and you should not.
• Are under 18. It is illegal to sell or supply vapes to anyone under 18 in the UK, and we check age on every order.
• Want adjustable wattage, temperature control or large clouds. A fixed-output kit like this offers none of that.
• Prefer a tobacco or menthol flavour. Both flavours here are sweet fruit profiles.
• Would rather refill with bottles of your choice. A refillable pod system is cheaper over the long run, and we stock several.
• Are pregnant or breastfeeding, or have a medical condition, and have not spoken to a healthcare professional first.

There is also a middle group. If you are a heavy smoker with no experience of vaping, a 20mg prefilled kit is an easy starting point, but you may find a refillable system with a choice of strengths gives you more control as you adjust. A kit like this makes sense as a first purchase because the cost of being wrong is low.

Finally, remember that a vape is a tool for adults trying to move away from cigarettes. If you are using one and want to stop nicotine altogether, there is free support from NHS stop smoking services, and it is worth using it.

How to use it, step by step

Using a prefilled pod kit is straightforward, but a few small habits make the difference between a clean first draw and a disappointing one. Follow these steps in order the first time.

• Step 1, check the box. Confirm the device, the pod or pods and any charging cable are present, and that the strength matches what you ordered, 10mg or 20mg. If anything is missing or damaged, contact us before you use it.
• Step 2, remove packaging. Take off any plastic film, seal or plug from the pod and the mouthpiece. Some pods have a small cap over the liquid path. Do not pierce or open the pod.
• Step 3, seat the pod. Push it into the battery body until it clicks or sits flush. If the device uses a magnetic connection, it should pull into place.
• Step 4, wait a few minutes. Leave the assembled device upright for five to ten minutes so the cotton can saturate. This is the single most useful habit for avoiding a dry first hit.
• Step 5, charge if needed. If the battery was not fully charged in the box, give it a top-up before you start.
• Step 6, take gentle first draws. Take two or three short, light draws, pausing between each, so the coil wets out and warms up.
• Step 7, vape at your own pace. Draw slowly for around two to three seconds, hold briefly if you like, then exhale. Do not chain draw. Rapid, repeated draws overheat the coil and shorten pod life.
• Step 8, swap pods when needed. When flavour fades, vapour thins or the taste turns burnt, pull the pod off and fit a fresh one, then repeat the short wait before using it.

A few day-to-day habits help too. Keep the device upright when you are not using it, and clean the metal contacts between pod and body with a dry cotton bud now and then. Do not use anything damp or alcohol-based on them. Store it somewhere at room temperature, away from children and pets, and keep any spare pods in a cool, dry place.

If you have two flavours in the box, many people use one pod until it is finished before opening the next. Others alternate daily to keep the flavours interesting. Either approach works, but sticking with one pod until it is empty makes it easier to judge how long each one really lasts for you.

Troubleshooting common problems

Most problems with pod kits have simple causes, and many can be fixed in a minute. Work through the list below before assuming the device is faulty.

• No vapour, device does not fire. Check the battery is charged. Remove and reseat the pod, making sure it clicks fully into place, and wipe the contacts with a dry cloth. Confirm that any packaging plug has been removed from the airflow channel.
• Weak vapour or thin flavour. The pod may be running low, the battery may be near empty, or you may be drawing too quickly. Slow the draw down and try a fresh charge. If a new pod is also weak, it needs more time to saturate.
• Burnt or toasted taste. This usually means the coil has dried out. Stop using that pod, since further draws only make it worse, and replace it. To avoid it next time, wait five to ten minutes before using a new pod and do not chain vape.
• Gurgling or spitting. A little condensation in the airflow path is normal. Blow gently back through the mouthpiece, away from your face, or wipe it with a tissue. Persistent spitting suggests the pod is overfilled or overheated.
• Leaking. Check the pod is seated properly and wipe away any liquid. Keep the device upright and out of heat. If a pod leaks continuously, replace it and contact us if it is a fault on arrival.
• Harsh throat hit. The strength may be too high for you, or you may be drawing too hard. Try slower, shorter draws, and if it persists consider the 10mg version.
• Not charging. Try a different cable and port. Check that the plug is fully inserted and that the charging port is free of lint. If a charge light never appears and the device is cold and unresponsive, it may be a battery fault.
• Flashing light. Many devices flash to signal low battery or a short circuit. Charge it first. If it keeps flashing after a charge, remove the pod and try another.
• Pod will not seat. Check it is the right pod for the device and that nothing is stuck in the connector. Never force it.

If you have worked through these and the device still misbehaves, do not keep trying. Stop using it, keep the packaging, and contact us with a clear description of the fault. Anything faulty or wrongly sent is our responsibility to put right.

Safety comes first. If the battery gets hot, swells, smells of chemicals or makes a hissing sound, put it down on a non-flammable surface away from anything that could burn, and do not charge or use it again.

Value for money

The price is £10, and the sensible way to judge value is by running cost rather than by the puff count on the box.

Start with a simple calculation. If a kit like this lasts you ten days of moderate use, that is £1 a day. If it lasts five days, it is £2 a day. Your own number depends on pods in the box, nicotine strength, how often you vape and how long your draws are, so test it with your first kit and then you will know. Weigh it against cigarettes: a pack of 20 in the UK now costs well over £15, so even a heavier vaping habit at this price usually works out cheaper than smoking.

Points that affect value in practice:

• Two flavours in one kit. If the box contains two pods, you get variety without buying two separate devices, which is a real saving over buying two single-flavour bars.
• A rechargeable battery. You are not throwing away a battery with every pod, which is a better use of materials than the old single-use model.
• Free UK delivery from £20. At £10 each, two kits reach the free delivery threshold. Weekday orders placed before 4pm are dispatched the same day.
• Hidden costs. There are few. You may want a spare charging cable, and replacement pods will cost extra once the kit is used up.

What you should not rely on is the 30,000 figure. A big rating is a marketing number, not a measure of what you will get for your money. Judge the kit on what you can verify: pod count, strength, flavour and how long it actually lasts you.

Where it is less competitive is the long run. A refillable pod system with bottles of nicotine salt e-liquid can cost noticeably less per day once you own the hardware, because liquid is cheap compared with a whole new prefilled pod. The trade-off is time, a little learning, and the chance of spills. If you value convenience, a prefilled kit at £10 is fair value. If you vape heavily and want the lowest daily cost, a refillable setup deserves a look.

As we cannot resell an opened consumable, opened items are outside our returns policy, so it makes sense to buy the strength you are most confident about, and to try a single kit before stocking up.

How it compares, and what to do with it afterwards

A fair comparison needs to name alternatives and say where each one wins. Here is how this kit sits against other options in our catalogue and the wider market.

• Solobar 30000 (sealed bar, £10.99 on this site). A single-flavour rechargeable bar with no pods to swap, rated at 30,000 puffs. It is simpler, with one flavour and nothing to fit, but you have no way to change flavour mid-life. The pod kit costs a little less and offers two profiles, while the bar asks even less of you.
• Snowplus Swift Prefilled Pod Kit (£8 on this site). A cheaper prefilled pod kit with a smaller range of flavours. If price is the main concern, it is the lower-cost entry, though a Solo Bar kit offers a wider choice of combinations.
• Al Fakher 30K Hypermax pods. Pods designed for their own device, offered in many flavours. Worth a look if you already own the matching hardware, because you can reuse the battery.
• Refillable pod systems from makers such as Vaporesso and Oxva. Cheaper per day over time, with free choice of liquid and strength, but more setup, more maintenance and more room for error. A good move once you know what you like.
• Larger rechargeable bars from brands such as Elf Bar and Lost Mary. Similar convenience, usually sealed. Choose on flavour and price, as the experience is much the same.

The honest summary is that this kit competes on simplicity and two-flavour variety at a low price, not on lowest cost per day or on adjustability. If those are your priorities, one of the other routes will serve you better.

Recycling and disposal. A vape is electrical waste and contains a lithium battery, so it must never go in the household bin or the kerbside recycling box. Batteries in bins cause fires in collection vehicles and waste sites. When the kit is finished, take the whole device, including used pods, to a recycling point.

• Most vape shops and many larger retailers that sell vapes must accept old devices for recycling, usually in a marked bin near the till.
• Household waste recycling centres run by your local council take small electricals and vapes.
• Recycle Your Electricals has an online postcode finder for your nearest drop-off point.
• Do not try to dismantle the device or remove the battery yourself.

Recycling the kit properly recovers the metals and keeps the battery out of landfill, and it is the least you can do with a product built around a rechargeable cell.
