Lost Mary BM600 Prefilled Pods PB Cloudd: what it is and who it is for

Lost Mary BM600 Prefilled Pods PB Cloudd is a replacement pod for the Lost Mary BM600 rechargeable device, filled at the factory with 20mg nicotine salt e-liquid in a cotton candy flavour with a cooling finish. Instead of throwing away a whole vape when the liquid runs out, you keep the battery body and click in a fresh, sealed pod that already carries its own mesh coil. There is nothing to pour, nothing to prime and nothing to adjust. The pod is rated at 600 puffs by the manufacturer, which is where the BM600 name comes from.

Lost Mary is a name most UK adult vapers will have seen on shop counters for several years, and the BM600 line is the compact, light-use end of the range. It is aimed at adult smokers who want a simple draw-and-go experience without learning about coils, wattage or airflow rings. If you have used a small pod kit before, the format will feel familiar. If you are coming from a disposable, the main change is that the battery stays with you and only the pod is replaced.

That change matters more than it used to. Since 1 June 2025 it has been illegal to supply single-use disposable vapes in the UK, and rechargeable devices with replaceable pods are the format that keeps the grab-and-go convenience people liked while producing less waste per puff. The battery, which is the most resource-heavy part of any vape, is reused many times instead of being thrown away after a few days.

A quick note on the name. PB Cloudd is how the flavour is listed, and on the pack and in many catalogues it appears as P&B Cloudd. We do not try to expand the abbreviation because the maker does not publish one. What we can say, from how the flavour is categorised, is that it sits in the cotton candy family with an ice element, and we cover that properly in the flavour section below.

What to expect on the listing and in the packaging:

• a sealed, prefilled 2ml pod with an integrated mesh coil
• 20mg/ml nicotine salt e-liquid, which is the highest strength permitted in the UK
• a pod that fits the Lost Mary BM600 device only, so check you already own a compatible battery body before ordering
• no battery or charger inside the pod itself, because power comes from the device

This product is for adults aged 18 or over who already smoke or vape. It contains nicotine, which is addictive, and it is not intended for non-smokers, young people, or anyone who is pregnant or breastfeeding.

Specifications at a glance

Puff counts and battery sizes are quoted by manufacturers and vary a little between sources, so this list sticks to what can be stated with confidence for this pod and the wider BM600 family. The printed pack always has the final word.

• Product type: prefilled replacement pod for the Lost Mary BM600 rechargeable device
• Flavour: PB Cloudd, a cotton candy profile with a cooling finish
• Rated puffs: 600 per pod, as quoted by the manufacturer
• E-liquid capacity: 2ml, which is the maximum size allowed for a pod or tank in the UK
• Nicotine strength: 20mg/ml (2%) nicotine salt, the highest strength allowed in the UK. This listing is offered in 20mg only
• Nicotine in the full pod: about 40mg (2ml at 20mg/ml). That is the amount in the liquid, not the amount a person absorbs
• Coil: integrated mesh coil, replaced every time you replace the pod
• Draw style: mouth-to-lung, with a light draw similar to pulling on a cigarette
• Battery: not in the pod. The BM600 device is commonly quoted at around 550mAh with USB-C charging, so confirm on the device listing
• Compatibility: Lost Mary BM600 device only. Pods are not interchangeable between brands
• Age restriction: 18+, with age verification on every order

Two of those figures deserve explanation. The 2ml capacity and the 20mg/ml strength are both UK legal limits rather than brand decisions, which is why every legal prefilled pod in this category quotes the same two numbers. Real differences between products therefore come from the coil, the liquid recipe and how well the device behaves, not from headline capacity or strength.

The 600-puff rating is a comparison figure. It comes from machine testing with a fixed puff length and a fixed gap between puffs. A person drawing longer or more often will get fewer puffs from the same pod, and a person taking short, gentle pulls will get more. Use the number to compare one pod with another, not as a promise about how many days it will last you.

Performance and puff delivery

The headline figure is 600 puffs from a 2ml pod. Divide the liquid by the puffs and you get roughly 3.3 microlitres of e-liquid per puff (2,000 microlitres divided by 600), which is a modest amount and typical of a light mouth-to-lung pod. It tells you what sort of experience to expect: a tidy, contained draw with a compact cloud rather than a dense one.

In daily use the arithmetic works out like this. A person taking around 100 puffs a day gets about six days from a pod, someone taking 300 puffs gets roughly two days, and a heavier user at 500 or more puffs a day will be changing a pod daily. Those are working estimates, not guarantees, because the 600 figure comes from lab testing and human puffs are longer, shorter, closer together or further apart than the lab pattern.

What you notice first is the throat hit. At 20mg/ml in a nicotine salt formulation, the hit is firm but rounder than the same strength in older freebase liquids, which is a large part of why salt nic took over the pod category. Vapour production is moderate. The mesh coil heats quickly, so the first puff of a session carries as much flavour as the fifth, and the taste stays reasonably steady until the liquid is nearly gone.

Several things affect how long a pod lasts and how it performs:

• Puff length. A three-second draw uses roughly twice the liquid of a 1.5-second draw. Short, gentle pulls extend the pod and keep the flavour cleaner.
• Puff spacing. Chaining puffs back to back lets the wick fall behind the coil, which gives a hot, thin or slightly burnt taste. Leaving 20 to 30 seconds between puffs gives the cotton time to resaturate.
• Device battery level. A tired battery lowers coil temperature, so vapour thins out and flavour dulls before the pod is empty. Recharge when the device warns you rather than running it flat.
• Storage and temperature. Cold pods draw thick, and hot pods thin out and can leak. Keep spares at room temperature, upright, away from windowsills and parked cars.

The end of a pod announces itself fairly clearly. Flavour fades first, then vapour thins, and finally you get a dry or toasted note. When you reach that point, stop and swap rather than pushing through, because dry puffs taste unpleasant and shorten the life of the coil without giving you anything back.

Flavour profile: PB Cloudd and the wider BM600 range

We would rather be straight with you than invent tasting notes. PB Cloudd is categorised in our catalogue as a cotton candy flavour with an ice element, and the name itself points the same way. Expect a spun-sugar sweetness, the warm, slightly caramelised note you get from fairground candy floss, and a cool finish on the exhale rather than a hard menthol blast. It is a dessert-style flavour, not a fruit one, and not a tobacco or mint one either.

How sweet is it? Cotton candy is one of the sweeter flavour families, so this is not a light, dry or subtle profile. If you enjoy sweets, sherbet or sugary drinks, the direction will feel familiar. If you prefer the crisp, slightly sour edge of a berry flavour or the clean bite of menthol, this will probably read as too sugary. Sweet flavours also tend to coat the mouth, so some people find they want water between sessions.

The ice element works as a finish rather than a headline. In most cooled flavours of this type the cooling shows up after the inhale, around the back of the throat and on the exhale, and it lifts the sweetness so it does not feel heavy. The cooling is mild to moderate, not the numbing level you get from dedicated menthol pods.

If cotton candy is not what you are after, the BM600 pod range in our shop covers a wide spread of other styles. A few worth knowing about:

• Blue Razz Ice: candied blue raspberry with a cooling finish
• Watermelon Ice: juicy melon with a light chill
• Strawberry Ice: sweet, jammy strawberry with cooling on the exhale
• Pink Lemonade: a sweet-sharp citrus profile
• Triple Mango: a ripe, tropical, fruit-forward option
• Peach Ice: soft stone fruit with a cool edge
• Blackberry Ice: darker, tarter berry with some chill
• Menthol and Mint Tobacco: for people who want a drier, cleaner profile

Availability changes with distributor stock, so treat that list as a snapshot rather than a promise. The line runs to dozens of flavours in total.

One practical point about sweet flavours: after a few days on the same one, many people stop tasting it as clearly. That is ordinary palate fatigue, not a fault with the pod. If a flavour seems to fade, a day on something different, or simply a glass of water and a short break, usually brings it back. Flavour is personal, and because an opened pod is a consumable we cannot resell, the multibuy is a sensible way to try a cotton candy pod alongside a fruit one.

Design and build quality

A prefilled pod is a simple object, but a few details separate a pod that behaves well from one that does not. The housing is moulded plastic, built to hold 2ml of liquid with a mouthpiece at one end and electrical contacts and an air path at the other. The mouthpiece is shaped for a mouth-to-lung draw, and the opening is narrow enough that the vapour feels cool and the flavour stays concentrated.

The pod ships sealed. Inside, the liquid sits around a cotton wick that feeds the mesh coil. Seals and small silicone parts keep the liquid where it belongs while the pod is on the shelf, in your bag or sitting on the side of the device. If a pod arrives with liquid on the outside of the housing or a damaged seal, do not use it. Contact us with your order number and a photo, and UK consumer law on faulty goods applies.

Things worth checking when you unpack:

• any protective film, cap or plug over the mouthpiece and base has been removed before the pod goes in the device
• the contacts on the base are clean and dry
• the housing is not cracked and the liquid chamber looks full
• the pod seats firmly when you press it into the device, with no wobble

A word on refilling. This is a prefilled, factory-sealed pod, and it is not designed to be refilled. Opening it, drilling it or topping it up with your own liquid risks leaks, a damaged seal and an unpredictable coil, and it also means you can no longer be certain what is in the pod. If you like the idea of using your own liquid, a purpose-built refillable pod kit is the right tool for that job, and the comparison section below covers the trade-offs.

Size and weight are where the BM600 format earns its place. A pod this size is light, fits in a pocket or the small compartment of a bag, and the whole device stays small enough that you barely notice it. The trade-off for that compactness is capacity: there is only 2ml in each pod, so heavier users will swap pods more often than they would with a larger tank.

Battery and charging

The pod itself holds no battery. Power comes from the Lost Mary BM600 device it clicks into, and that device is commonly quoted at a rechargeable battery of around 550mAh with USB-C charging. Check the device listing for the exact figure, because we would rather you rely on the maker's number than ours.

Here is how to think about a battery of that size. A 550mAh cell at a nominal 3.7 volts holds a little over two watt-hours of energy. A small mesh pod draws a few watts for each puff of one to three seconds, so the arithmetic suggests a full charge covers roughly one pod's worth of puffs, give or take your puff length. That fits with how the BM600 format is designed to be used: swap the pod and top up the device at roughly the same time.

Charging tips that apply to any small lithium device:

• Use the supplied or a decent-quality USB-C cable and a standard 5V phone-style adapter or a computer port. A typical full charge takes somewhere around 45 to 60 minutes from a 1 amp source, and longer from a weak port.
• Do not charge unattended overnight, on a bed, sofa or under a pillow, or in direct sun. Charge on a hard, uncluttered surface where you can see the device.
• Stop using any device that is swollen, hot, damaged, or has a frayed cable. Take it to a recycling point instead of charging it again.
• Do not leave the device in a hot car or at freezing temperatures. Extreme heat and cold both shorten battery life.
• Do not mix loose batteries or metal objects with the device in a pocket or bag.

You can charge the device with the pod fitted or removed. Some people prefer to take the pod out while charging, because it keeps the contacts clean and avoids any warmth around the liquid. When the battery is low you may see the indicator light on the device flash, and performance will start to drop off: vapour thins, flavour dulls and the draw becomes weaker. If you see that, recharge before the next session.

Battery condition affects flavour more than people expect. Because the coil heats less strongly when the battery is low, a half-empty pod on a nearly flat battery can taste far worse than the same pod on a full charge. If a pod seems disappointing, check the battery before you blame the liquid.

Mesh coil technology

The coil is the part that turns liquid into vapour, and in this pod it is a mesh coil built into the pod itself. Instead of a round wire wrapped in a spiral, a mesh coil is a thin, flat, perforated sheet of resistance metal that sits against the cotton wick. The pattern of small holes gives a much larger heating surface than a single wire, and it spreads heat across more of the wick at once.

That design has practical effects for a user:

• Quicker ramp-up. The coil reaches working temperature almost immediately, so the first puff is not weak or delayed.
• More even vaporisation. Heat is spread across a wide area, which reduces the hot spots that cause burnt or scratchy tastes.
• Better flavour definition. Even heating tends to bring out the sweet, layered notes in a recipe like cotton candy rather than flattening them.
• Steadier output through the pod's life. A larger surface area is less sensitive to small changes in wicking, so flavour holds up well until the liquid runs low.

Mesh coils sit well alongside nicotine salt liquids. Salts are used at higher strengths in lighter, lower-power devices, and a mesh coil is efficient enough to produce a satisfying amount of vapour without needing much power. Coil resistance in the region of one ohm is typical for this class of pod, but the maker does not print a figure for this one, so we do not quote one.

The coil is part of the pod and is not designed to be replaced separately. That is a feature, not a limitation: every time you fit a new pod you also fit a new coil, so you do not have to think about coil life, priming new coils or cleaning old ones. The downside is that when the liquid runs out the coil goes with it.

To get the most from the coil, a few habits help. Let a new pod rest for about a minute after fitting so the wick can fully saturate. Draw gently on the first few puffs rather than taking a long pull straight away. Avoid chain puffing. And if you ever taste a dry, scorched note while the pod still has liquid in it, put the device down for a few minutes and try again with shorter puffs before assuming the pod is faulty.

Choosing your nicotine strength

This pod is listed in 20mg/ml only. That is the highest strength allowed for nicotine vaping products in the UK, so it sits at the upper end of the scale rather than in the middle. Understanding what that means will help you decide whether this is the right pod for you.

The 20mg/ml figure means 2% nicotine by volume, so a full 2ml pod holds about 40mg of nicotine in the liquid. Nicotine salt formulations deliver that nicotine with less throat harshness than traditional freebase liquid at the same strength, which is why you can use a high strength in a small pod without it feeling rough. The throat hit is still noticeable, and it is what many people moving from cigarettes are looking for.

As a rough guide, and not as medical advice:

• Heavier smokers who are used to a pack a day, or close to it, are the group 20mg is generally aimed at.
• Moderate smokers may find 20mg satisfying but strong, and will probably puff less often as a result.
• Light or occasional smokers and ex-smokers often find 20mg too strong. Signs include feeling lightheaded, queasy, a headache or a racing pulse. If that happens, stop, take a break and consider a lower strength in a different product.

If you want something milder, this particular listing will not offer it. Lost Mary BM600 pods in other flavours are offered in 10mg in many cases, and the 10mg option is worth looking at if you want to cut back. Check the product page of the flavour you like, since strengths vary by flavour and stock.

Nicotine is addictive, and nobody who does not already use nicotine should start. If you are trying to stop smoking, your pharmacist or local NHS stop smoking service can give personalised advice, and that is a better source than a retail page. We make no health claims about this product and none should be read into anything here.

A practical tip for anyone on 20mg: because salts are efficient and a pod is small, many people use fewer puffs than they expect. Pay attention to how you feel after the first hour or two, and if you notice you are drawing heavily without really wanting to, put the device down. The aim is to satisfy a craving, not to chain through the pod.

Who it suits, and who should skip it

The BM600 pod format works well for a particular kind of adult user. Here is who it fits.

• Adult smokers switching to vaping who want a simple, familiar-feeling draw with a firm throat hit and no setup.
• Former disposable users who liked the convenience but want a rechargeable device with replaceable pods now that single-use vapes can no longer be sold in the UK.
• Light to moderate users who take a few hundred puffs a day at most, and for whom 2ml lasts a sensible number of days.
• People who want a pocketable device and are happy to carry one spare pod rather than a larger kit.
• Anyone with a sweet tooth. Cotton candy flavours reward people who like sweets, sugary drinks and dessert flavours.

And here is who should probably look elsewhere.

• Non-smokers and anyone under 18. This product contains nicotine and is for adult smokers and vapers only. It is also unsuitable during pregnancy or breastfeeding.
• People who do not own a compatible BM600 device. The pod does nothing on its own, and it does not fit other brands' batteries.
• Heavy vapers. At 600 puffs per pod, anyone taking several hundred puffs a day will be swapping pods daily, and a larger tank or a refillable kit will probably suit their routine better.
• People who want lower nicotine. This listing is 20mg only.
• People who dislike sweet flavours. Cotton candy is sweet by design. If you want something dry, sharp or tobacco-like, choose a menthol, mint or tobacco pod instead.
• Tinkerers. If you enjoy adjusting airflow and power or mixing your own liquid, a closed prefilled pod gives you nothing to adjust.

Being honest about this up front saves money. The format is built for simplicity, and its strengths are the same things that limit it for enthusiasts. If simplicity is what you want, it does that job cleanly. If you want control, you will find the BM600 frustrating.

How to fit, activate and use the pod

Using a prefilled pod takes less than a minute, and there is no activation step beyond fitting it and drawing. Here is the process.

• Step 1. Make sure you are using a Lost Mary BM600 device and that it has some charge. A flat battery will give weak or no vapour.
• Step 2. Take the pod out of its packaging and remove any protective cap, film or plug from the mouthpiece and from the base. Check that the housing is intact and there is no liquid on the outside.
• Step 3. Line the pod up with the opening on the device and press it in until it seats firmly. You should feel it settle with no wobble.
• Step 4. Wait for about 30 to 60 seconds. This lets the cotton wick draw liquid to the coil, so the first puff does not hit a dry wick.
• Step 5. Draw gently through the mouthpiece for one to three seconds, as you would on a cigarette, holding the vapour in your mouth briefly before inhaling. The device should respond to the draw without a button press.
• Step 6. Pause for 20 to 30 seconds between puffs and avoid chain vaping.

Look after the pod between sessions. Keep the device upright where possible, avoid leaving it in a hot place, and keep the mouthpiece clean. If you are carrying a spare, keep it in its sealed packaging until you need it.

To swap a pod, pull the old one straight out of the device and press the new one in. You do not need to clean the contacts every time, but a quick wipe of the base with a dry tissue can help if you see liquid residue.

When a pod is finished, dispose of it responsibly. In the UK, vapes and their components contain plastics, residual liquid and in the case of the device a lithium battery, and they should not go in household bins or kerbside recycling. Shops that sell vapes are expected to take used products back, and many household waste recycling centres accept them too. Use a vape or small electricals drop-off point, and keep used pods away from children and pets until you do.

Finally, store pods and the device out of reach of children and pets. Nicotine e-liquid is harmful if swallowed or if it gets on the skin or in the eyes. If that happens, seek medical advice and follow the guidance on the pack.

Troubleshooting common problems

Most problems with prefilled pods have simple causes. Here are the ones we see most often and what to try.

• No vapour or no response when you draw. Check the battery first and charge the device if it is low. Then remove the pod and refit it, making sure it seats fully. Look for any protective cap or film that was not removed, and check the contacts are clean and dry.
• Weak flavour from a new pod. Wait a minute for the wick to saturate and take a few gentle puffs. If the pod is new and the battery is full, it may simply need more time.
• Dry, burnt or scorched taste. This usually means the wick is running behind the coil. Pause for a few minutes, draw gently, space your puffs out, and do not chain vape. If the pod is nearly empty, it has reached the end of its life and should be replaced.
• Gurgling or liquid in the mouthpiece. Excess liquid can pool when a pod is stored on its side or drawn too hard. Tilt the device so the mouthpiece faces down, blow gently through the mouthpiece to clear it, and wipe it with a tissue.
• Leaking from the base. Do not use a pod that is leaking. Remove it, wipe the device contacts clean and dry, and contact us if the pod arrived like that. Heat and pressure changes during travel can contribute, so avoid leaving pods in hot places or in a bag on a flight without care.
• Device not recognising the pod. Check the pod is the right type for the BM600, that the contacts line up, and that nothing is blocking the connection. Try cleaning the contacts with a dry cotton bud.
• Harsh throat hit. The strength is 20mg/ml and the hit is firm by design. Shorter, gentler puffs help, but if it is too much for you, a lower-strength product may be a better fit.
• Pod seems to run out early. Long, heavy or frequent puffs use liquid quickly, and the 600-puff figure is a lab number. Compare how you use it with the puff-spacing tips earlier on this page.
• Indicator light flashing. This commonly signals low battery on small devices. Charge it and check the device guidance.

If none of that fixes the problem, get in touch with your order number and a short description or photo. Faulty goods are covered by UK consumer law, and we will look at a replacement or refund. We cannot resell or exchange opened consumables that are simply not to your taste, so please try one flavour at a time or use the multibuy if you are unsure.

Value for money and how it compares

Cost per puff is the quickest way to judge value. At the listed single price of £4.95, a 600-puff pod works out at roughly 0.83p per puff, or about £2.48 per millilitre of liquid. On the 3 for £12 multibuy deal each pod costs £4.00, which brings the cost down to roughly 0.67p per puff. For someone taking about 300 puffs a day, that is around £2.48 a day at the single price and £2.00 a day on the multibuy, before you count the one-off cost of the device.

Those figures are fair for a light-use prefilled pod, though not rock-bottom. You are paying for convenience: no bottles, no measuring, no refill spills, and a coil that is fitted and ready. Here is how that compares with the main alternatives.

• Other prefilled pod systems. Elf Bar's Elfa line, for example, sells prefilled pods in a broadly similar size and strength class, and we also stock them. Elf Bar sells a Cherry Cloudd pod for the Elfa device, but that is a different flavour and the pods are not interchangeable with the Lost Mary BM600. Choose on flavour, device feel and price rather than assuming one is better in general.
• Larger Lost Mary kits. Lost Mary also lists higher-rated kits such as the BM6000 family. Those bigger puff ratings are delivered across several pods, because the 2ml cap still applies to each, so compare the price per pod rather than the headline number.
• Refillable pod kits. Kits from brands such as SMOK and Vaporesso let you use your own nic salt liquid. A 10ml bottle holds five times as much as a 2ml pod and commonly sells for a similar price to one or two prefilled pods, so the running cost can be lower. The trade-off is that you have to fill, maintain and replace coils yourself, so it takes more effort.
• Single-use disposables. These are no longer legal to supply in the UK, so they are not a comparison point, which is a good reason for the rechargeable pod format to exist.

The device you already own matters here. If you have a BM600 battery body, a pod is a cheap way to keep going. If you are starting from scratch, remember to add the device cost, and consider whether a larger kit would give you a better per-day cost for your habits.

Finally, factor in reliability. Genuine product matters with a nicotine device, and we only list stock sourced through UK distributors. Delivery is free over £20, and orders placed before 4pm are dispatched the same day. If you intend to buy more than one pod, the multibuy is also the cheapest way to build a small stock of spares.
