Hayati Pro Max Plus 4000 Blue Razz replacement pods: overview

These are the Hayati Pro Max Plus 4000 Replacement Pods in Blue Razz, the GB-market version of a prefilled pod made for the Hayati Pro Max Plus 4000 rechargeable device. If you already own the device and you are tired of rinsing out tanks, winding coils or topping up bottles, a prefilled replacement pod is the simplest way to keep going: click the old pod out, click a new one in, and carry on. Blue Razz is the flavour on this page, and it is one of the most familiar profiles in UK vaping, built around sweet blue raspberry with a slightly tart finish.

It helps to be clear about what you are buying. This listing is for the pods only. The battery device is a separate product, and the pod is designed to fit the Hayati Pro Max Plus 4000 hardware, so it is worth checking that you own the right model before you order. Brands often reuse similar names across different formats, and a pod built for one body will not necessarily seat properly in another. If you are unsure, compare the pod connector and the shape of the mouthpiece against your device, or message the shop before you buy.

The word 'Replacement' matters in the UK. Since 1 June 2025 it has been illegal to supply single-use disposable vapes, which pushed the market towards reusable devices with swappable pods. A device you recharge, paired with pods you replace and recycle, is the legal and more sustainable route, and it is the category these pods belong to. Everything on this page is written with that in mind: UK-specification liquid, nicotine at or below the 20mg/ml legal ceiling, and a pod size that sits within the 2ml limit that applies to prefilled and refillable containers.

The rest of this guide walks through the specifications, how Blue Razz actually tastes, how many puffs you can realistically expect, the build quality of the pod and device, battery and charging, the mesh coil, how to choose a nicotine strength, who the pods suit, how to fit and use them, what to do when something goes wrong, and how the cost compares with other options. It is written for adult smokers and existing vapers in the UK. If you do not currently smoke or vape, nicotine products are not for you, and if you are under 18 you cannot legally buy them.

Key specifications at a glance

Specifications for vape products are easy to misread, so here is a plain summary of what this pod is and what the numbers mean. Where a figure varies between production batches or depends on how you vape, it is described as typical rather than exact. The pack and the device label are always the final word.

• Product type: prefilled replacement pod for the Hayati Pro Max Plus 4000 rechargeable device (device sold separately)
• Flavour: Blue Razz (blue raspberry)
• Market: GB specification, for adults aged 18 and over
• E-liquid capacity: up to 2ml per pod, the UK legal maximum for prefilled and refillable containers
• Nicotine: nicotine salt liquid at or below the UK limit of 20mg/ml (2%)
• Coil: integrated mesh coil, sealed inside the pod
• Typical pod life: several hundred puffs per pod, depending on draw length and frequency
• Charging: the device recharges by USB-C on current models; the pod itself has no battery
• Refilling: not designed to be refilled; replace the pod when it is empty

The question most buyers ask is what the '4000' in the name means. In practice it is best read as a model-line name rather than a promise of how many puffs a single UK pod will deliver. UK law caps a prefilled pod at 2ml, and 2ml of liquid simply cannot supply four thousand puffs. A realistic planning figure for a 2ml nicotine salt pod with a mesh coil is somewhere between 500 and 800 puffs, depending on how long and how hard you draw. That is an honest estimate rather than a guarantee, and we would rather you budget around it than feel misled later.

The 20mg/ml ceiling is the other number worth understanding. It is the maximum nicotine concentration allowed in nicotine-containing e-liquid sold in the UK, and it is expressed either as 20mg/ml or as 2%, which are the same thing. Packaging for UK products must also carry the standard nicotine health warning, a batch number and a notification reference, so if a pod arrives without proper labelling, do not use it and contact the seller.

Finally, the pod connects to the device through contact points and a push-fit seat. These are small details that matter in daily use, because a dirty or misaligned connection is the most common reason a new pod seems to do nothing. The troubleshooting section below covers how to check it.

Blue Razz flavour profile

Blue Razz, short for blue raspberry, is a confectionery flavour rather than a literal fruit. If you have ever had a blue raspberry slush, a sherbet-style sweet or a blue ice lolly, you already know the general idea. It is sweet and bright, with a gentle tang in the background that stops it tasting flat. It is not a realistic raspberry, which is usually tart and slightly earthy, and that is exactly why so many vapers like it: it is an easy, friendly, candy-like flavour that does not demand attention.

On the inhale, expect a clean wave of sweet berry. The first impression is sugary and light rather than syrupy, and there is a faint tartness that arrives a moment later. On the exhale the sweetness fades quickly and leaves a soft raspberry note on the tongue, without the heavy aftertaste that some dessert flavours leave. Because the profile is built around fruit and candy rather than cream or custard, it tends to feel lighter in the mouth and is easier to vape for a long session than richer flavours.

This version is a standard Blue Razz rather than an icy one. There is no strong menthol or cooling agent pushing the throat hit, so the vapour feels smooth and slightly warm rather than cold. If you want a chilled finish, check whether an ice variant of the same pod is listed alongside this one, because the flavour swap is simple and the nicotine strength and pod format stay the same.

A few practical points about how flavour behaves in a prefilled pod:

• The first few puffs can taste muted. The cotton needs a few minutes to wick fully, so give a fresh pod a short rest before judging it.
• Shorter draws taste better. A gentle two to three second pull gives cleaner flavour than a long, hard drag, which can scorch the cotton and flatten the sweetness.
• Flavour fatigue is real. After a few days on the same sweet profile, many vapers stop noticing the taste and assume the pod is failing. Switching to a different flavour for a day usually resets your palate.
• Sweet liquids leave residue. Sugary flavours can slowly build up on the coil, which is one reason a pod should be replaced rather than stretched far beyond its useful life.

If Blue Razz appeals, you will probably also enjoy other blue raspberry, blue sour raspberry, blueberry and fruit-candy profiles. If you usually prefer menthol, tobacco or dessert flavours, this is probably not the one to start with.

Performance and puff delivery

The Hayati Pro Max Plus 4000 pods are designed to be draw-activated. There is no button to hold and no setting to change: you inhale through the mouthpiece and the device fires. This is the main reason pod systems appeal to people moving away from cigarettes, because the action is simple and quick, and it mimics a cigarette more closely than a high-powered tank does.

Vapour production is moderate for a pod format, a little more generous than the lightest pen-style devices but well short of what a sub-ohm kit produces. That is deliberate. A mesh coil in a pod of this size is tuned for tight to slightly restricted draws, which suits nicotine salt liquid and keeps the nicotine delivery steady. If you are used to large clouds, you will find this noticeably gentler, and you should decide before buying whether that suits you.

Throat hit is smooth. Nicotine salts are made with a different acid balance than older freebase liquids, so a 20mg/ml salt feels far gentler on the throat than 20mg/ml freebase would, even though the nicotine content is the same on paper. Some smokers describe this as a softer, more cigarette-like satisfaction. Others, especially those used to low-strength freebase liquid, find 20mg salt stronger than they expect on the first day. The nicotine guidance section covers how to pace yourself.

Here is how to think about pod life in real terms:

• Per pod: a 2ml pod typically delivers somewhere in the range of 500 to 800 puffs. Short draws stretch it, long draws shorten it.
• Per day: a light user taking 100 to 150 puffs a day may get four to six days from a pod. A former pack-a-day smoker taking 250 or more puffs may finish a pod in two to three days.
• Per week: most regular users end up buying two to four pods a week, and it is sensible to keep a spare so you never go back to cigarettes because you ran out.

Consistency from first puff to last is generally steady in this kind of pod. The usual sign that a pod is close to empty is a sudden drop in flavour, followed by a hot or slightly burnt taste. When that happens, stop and swap the pod rather than pushing through, because dry puffs are unpleasant and can leave a taste that lingers for a while.

Finally, a note on expectations. No pod performs identically in every device on every day. Temperature, how full the battery is, how you hold the device and even how recently you replaced the pod all change the experience a little. If the performance seems far off from what is described here, the troubleshooting section is the place to start.

Design and build quality

A prefilled pod is a small, sealed component, and the quality of the build matters more than it looks. The parts that count are the seal around the liquid reservoir, the fit of the connector, the shape of the mouthpiece and the tamper-evident packaging. A well-made pod seats with a clear, firm click and sits flush with the body of the device. A badly made one wobbles, leaks at the base or refuses to make contact.

On arrival, run through a quick inspection before you fit the pod:

• Check the outer packaging. UK-market packs should be sealed and carry the nicotine health warning and a notification reference. A torn or unsealed box is a reason to contact the seller before use.
• Look at the pod body. The plastic should be smooth with no cracks, and the liquid level should look full with no obvious leakage inside the sleeve.
• Inspect the connector. The metal contacts at the base should be clean and dry. Wipe away any film with a dry tissue.
• Remove any protective film or plugs. Some pods ship with a small cover over the mouthpiece or air inlet. Take these off before the first puff.

The mouthpiece on pods of this type is typically a gently tapered shape that sits comfortably between the lips. It is designed for mouth-to-lung style use, where you draw vapour into your mouth first and then inhale, which matches the restricted airflow of the mesh coil. Moulded plastic is lightweight, and while it will survive being carried in a pocket or bag, it does not like being dropped on hard floors or left on a car dashboard in summer.

Heat is the enemy of any prefilled pod. Leaving the device in direct sunlight, a hot car or a hot pocket thins the liquid, can cause weeping from the air channel and shortens the useful life of the pod. Store pods upright in a cool, dry place, away from children and pets, and keep spares in their original packaging until you need them.

Environmental design is also worth a thought. A reusable device with replaceable pods produces far less waste than a single-use product, because the battery and body stay in service. The pod is the part that gets thrown away, and it contains a small coil and traces of nicotine, so it should be recycled properly rather than binned. The how-to-use section explains the options for UK drop-off points.

Battery and charging

The pod has no battery of its own. Power comes from the rechargeable lithium-ion cell inside the Hayati Pro Max Plus 4000 device, which is why the pod is cheap and light to replace. Devices in this size class commonly use a cell somewhere in the region of 500 to 650mAh, but you should check the figure for your own unit, as it can differ between batches. For most users that capacity lasts a day or two of moderate use, and often covers more than one pod between charges.

A few facts about charging that apply to nearly every pod device:

• Use USB-C where your device supports it. Current Pro Max Plus models charge through a USB-C port, and any decent phone charger or USB port will do the job.
• Avoid cheap, unbranded cables and chargers. A poorly made adapter can supply unstable current, which is hard on a small lithium cell.
• Do not charge it unattended for long periods. Charging overnight on a pillow, a sofa or any soft surface is a fire risk. Charge on a hard surface where you can see it.
• Unplug once the indicator shows a full charge. Leaving a device on charge indefinitely does not help the cell and is not recommended.
• Do not charge a damaged or swollen device. If the case is warped, hot to the touch or smells odd, stop using it and take it to a recycling point.

A full recharge on a device of this size normally takes a short while, often under an hour, although the exact time depends on the charger and the battery state. The device typically has an indicator light that shows charging and low battery states, but the colour codes vary, so refer to the leaflet that came with your unit.

If the device seems to run flat quickly, there are several things to check before blaming the battery. Cold weather reduces capacity temporarily. A pod that is almost empty draws more effort from the cell. A dirty charging port can interrupt charging, and a gentle clean with a dry wooden toothpick or a puff of air can fix it. Over a long time, lithium-ion cells lose capacity, and after several hundred charge cycles most users notice shorter runtime.

When a device finally comes to the end of its life, it must not go into household rubbish. UK law treats vapes as waste electrical equipment, and lithium batteries in refuse lorries and recycling plants are a known fire hazard. Take it to a vape recycling point or a household waste recycling centre, and return it to a retailer that offers take-back.

Mesh coil technology

The coil is the part of a vape that heats the liquid, and the one in this pod is a mesh coil. Instead of a single round wire wound into a spiral, a mesh coil is a thin flat sheet of metal with a fine grid pattern, wrapped around or pressed against the cotton wick. That grid has a much larger surface area than a spiral wire of the same size, and that is the reason this design has become the standard in modern pod products.

The practical benefits of a mesh coil are straightforward:

• Faster, more even heating. More of the cotton is in contact with heated metal, so the liquid vaporises evenly and the pod reaches full output within a fraction of a second.
• Cleaner flavour. Even heating means fewer hot spots, so sweet and fruity flavours like Blue Razz stay bright instead of turning flat or scorched.
• Lower power demand. A mesh coil can produce satisfying vapour at modest power, which is kind to a small battery and stretches runtime.
• More consistent from puff to puff. There is less variation between the first draw and the fiftieth, as long as the wick stays saturated.

Pods in this class are usually built around a resistance close to or above one ohm. That suits nicotine salt liquid, which is formulated to be vaped at lower power with tighter airflow. It also explains why this product feels closer to smoking than to using a large tank: the draw has some resistance and the vapour is warm rather than hot.

The coil is sealed into the pod, which means you cannot clean, rewick or replace it. This is a design choice. It removes the maintenance that puts many people off vaping and it guarantees a fresh coil every time you change pod. The trade-off is that you cannot extend a pod by rebuilding it, so the price of convenience is that the whole pod is a consumable.

Coil life depends on how you use the pod. The things that wear a mesh coil fastest are chain-vaping with no pause between puffs, very long draws, and continuing to vape after the liquid has run low. A dry coil heats the cotton directly, which causes a burnt taste and permanently damages the wick. Priming a new pod by waiting a few minutes after insertion, and swapping it as soon as the flavour fades, gives the coil the best chance of delivering consistent performance through the whole pod.

One more point on sweet flavours: sugars and sweeteners in the liquid caramelise slightly on the mesh over time, which gradually dulls flavour. That is normal and is another reason to treat the pod as a fixed-life item.

Nicotine strength guidance

Choosing the right nicotine strength is the single biggest factor in whether switching from cigarettes actually works. In the UK, the maximum allowed concentration is 20mg/ml, which is the same as 2%. Pods like this one are sold in nicotine salt form, and the strength printed on the pack is the figure to go by. If a particular pod is only sold at the top strength, you will see that on the listing.

As a general rule of thumb for nicotine salts, many vapers use the following as a starting guide. It is a rough guide, not medical advice, and individual tolerance varies a lot:

• More than ten cigarettes a day: a strength at or near 20mg/ml usually gives enough satisfaction to stop cravings pulling you back to smoking.
• Five to ten cigarettes a day: something in the range of 10 to 12mg/ml is often enough, although 20mg/ml can work with shorter, less frequent puffs.
• Fewer than five cigarettes a day, or social smoking: 5 to 6mg/ml is usually plenty, and a high-strength pod is likely to feel too intense.

How do you know if you have got it wrong? Too much nicotine tends to show up as dizziness, nausea, a racing heartbeat, sweating or hiccups, and a harsh feeling at the back of the throat. If that happens, stop vaping, drink some water and take a break. Too little nicotine looks different: you vape almost constantly, get irritable, and still crave a cigarette. If you are chain-vaping and not feeling satisfied, a higher strength may help.

If you have chosen a 20mg/ml pod and find it strong, there are ways to manage it without switching immediately:

• Take shorter, gentler puffs instead of long draws.
• Leave longer gaps between puffs, and put the device down between sessions.
• Avoid vaping on an empty stomach, which makes nicotine feel stronger.
• Consider a lower-strength product from the wider range if you consistently feel unwell on 20mg/ml.

Remember that nicotine is addictive. The aim for most adult smokers is to switch completely from cigarettes, because vaping is widely considered much less harmful than smoking tobacco, although it is not risk-free. Over time, many people reduce their strength gradually. Local NHS stop smoking services can offer free behavioural support and, in some areas, help with vaping starter kits, and they are worth contacting if you want a structured plan.

Pregnant or breastfeeding women, people with heart conditions or high blood pressure, and anyone taking regular medication should speak to a GP or pharmacist before using nicotine products. Nicotine products are for adults only and must be kept out of reach of children and pets.

Who these pods are for, and who should skip them

The Hayati Pro Max Plus 4000 Blue Razz pods fit a specific type of user. Understanding that helps you decide quickly whether they are the right buy or whether another product would serve you better.

These pods are a good match if you are:

• An adult smoker looking to switch. The draw-activated design, nicotine salt delivery and low-maintenance format are all aimed at people leaving cigarettes behind.
• Already using the Hayati Pro Max Plus 4000 device. If you own the hardware, replacement pods are the obvious way to keep it running.
• Someone who dislikes maintenance. No coils to buy, no bottles to pour, no cotton to wick. You swap the pod and you are done.
• A fan of sweet, fruity flavours. Blue Razz suits people who enjoy candy-style profiles and find tobacco or menthol flavours harsh.
• A user who wants something pocketable. The compact device and small pods travel easily, and a spare pod weighs almost nothing.

You may want to skip them if you are:

• Not an existing smoker or vaper. Nicotine is addictive and these products are not intended for people who do not already use nicotine.
• Under 18. It is illegal to sell nicotine vaping products to anyone under 18 in the UK, and age checks may apply to your order.
• Looking for large clouds or adjustable power. There is no wattage or airflow control, and the pod format is built for a tight draw.
• Counting every penny. A refillable pod kit with bottled liquid usually costs less per millilitre, as the comparison section explains.
• Dependent on a lower nicotine strength. If 20mg/ml is too high for your needs, check the available strengths on the listing before buying.
• Wanting a cooling menthol finish. This is a standard Blue Razz, so look for an ice variant if you prefer chill.

There is also a middle group worth mentioning: people who already vape with a refillable kit and want a simple, grab-and-go option for travel, nights out or backup. For them, a single device with a handful of spare pods is often more convenient than carrying bottles and a larger kit. Whichever group you fall into, the best approach is to start with one or two pods, see how they suit your habits, and buy more once you are sure.

How to fit and use the pod

Fitting a replacement pod takes under a minute and needs no tools. Follow the steps below the first time, and it will quickly become second nature.

• Step 1, check your device. Make sure the Hayati Pro Max Plus 4000 is charged. A near-flat battery can cause weak vapour and make a good pod seem faulty.
• Step 2, open the packaging. Inspect the pod for damage, leaks or a loose seal, and remove any protective film or plug.
• Step 3, remove the old pod. If you are replacing a used pod, pull it out in a straight line, rather than twisting or levering it, so you do not bend the contacts.
• Step 4, insert the new pod. Line up the connector and push it in firmly until it seats flush with the body. You should feel and hear it settle.
• Step 5, let it prime. Wait five to ten minutes before your first puff. This lets the cotton absorb liquid and prevents dry or burnt-tasting first draws.
• Step 6, take gentle puffs. Start with two or three second draws. There is no button to press: just inhale from the mouthpiece.
• Step 7, pace yourself. Leave a short gap between puffs. Continuous chain-vaping heats the coil too much and shortens pod life.

Day-to-day habits make a real difference to how pods perform. Store the device upright when you can, wipe condensation from the mouthpiece with a tissue, and avoid carrying it loose in a pocket with keys or coins, which can short the contacts. Keep it away from heat and direct sunlight, and bring it indoors on very cold days, because cold thickens the liquid and weakens performance.

When should you replace a pod? Change it when the flavour fades noticeably, when you start getting a hot or burnt taste, or when you can see the liquid level is nearly gone. Do not try to refill it. The pod is not designed for that, and attempts to open it can damage the coil or leave you with a leak.

Recycling used pods in the UK. A used pod contains a coil and traces of nicotine, so it should not go in the household bin. Instead:

• Take it to a vape recycling drop-off point, which many vape shops and some supermarkets now provide.
• Use the small electricals section at your local household waste recycling centre.
• Ask the retailer you bought from, since shops that sell vapes are required to offer take-back of used equipment.
• Keep used pods out of reach of children and pets until they are disposed of.

Never put pods, batteries or devices in kerbside recycling or general waste. Lithium batteries can ignite when crushed, and fires in bin lorries and recycling plants are a growing problem across the UK.

Troubleshooting common problems

Most problems with pod systems have a quick fix. Work through the likely causes below before assuming something is faulty.

• The pod is not recognised or nothing happens. Remove the pod and reseat it firmly. Check that the metal contacts on both the pod and the device are clean and dry, and wipe them with a dry cotton bud. Make sure the device has charge.
• Weak or no vapour. A new pod may need a few more minutes to prime. If the pod has been used for a while, it may simply be empty. Try a gentle puff, then a slightly longer one, and if there is still nothing, replace the pod.
• Burnt or hot taste. This usually means the liquid is nearly gone or you have been chain-vaping. Stop, let the device rest and replace the pod. A pod that has been burnt will not recover.
• Leaking from the pod or the device. Wipe away the liquid, check that the pod is seated correctly and that the seal is intact. Avoid storing the device on its side or in a hot place. Pressure changes during flights can also push liquid out, so carry the device upright and ideally with the pod removed.
• Gurgling or spitting sounds. Condensation is blocking the airway. Remove the pod, blow gently through the mouthpiece or wipe it with a tissue, and refit the pod.
• Flavour seems dull. Flavour fatigue is common with sweet profiles. Try a different flavour for a day. If a fresh pod tastes dull in a different device, the problem may be the pod itself.
• Indicator light flashing. This often signals low battery, a short circuit or a poor connection. Charge the device and clean the contacts. If the light continues flashing with a fresh pod and a full battery, check your leaflet for the meaning of the pattern.
• The device will not charge. Try another cable and another power source. Check the charging port for lint or debris and clean it gently with a dry wooden toothpick. If it still will not charge, stop using the cable to avoid damage.
• Sore or dry throat. Drink more water and take shorter puffs. A strength that is too high for you can also cause this.

If you have followed these steps and the problem persists, do not keep forcing the device. Make a note of your order number, take a clear photo of the issue and contact the shop. Under the Consumer Rights Act 2015, goods must be of satisfactory quality and as described, and a genuinely faulty item should be put right. Keep the pod and packaging to help the shop investigate. Do not attempt to open or modify the device or the pod, and never use a device that is hot, swollen or smells of burning.

Value for money and how it compares

Value in vaping is about more than the sticker price. What matters is the cost per day, the flavour and nicotine satisfaction you get, and how much effort the format demands. A prefilled pod trades a higher cost per millilitre for convenience, and that trade is only worth it if the convenience matters to you.

A simple way to judge cost is to work out price per puff and price per day. As a purely illustrative example, if a pod costs five pounds and delivers 600 puffs, that is a little under one penny per puff. At 200 puffs a day, you would spend roughly one pound sixty-five a day. Compare that with the price of a pack of 20 cigarettes in the UK, which is well over fifteen pounds, and the saving for a switching smoker is clear. Check the current price on this page and plug in your own figures.

Here is how this pod system compares fairly with some common alternatives:

• Elf Bar ELFA-style prefilled pod systems. These work the same way: a rechargeable device with sealed 2ml nicotine salt pods. The big advantage of the Elf Bar family is availability, since pods are stocked almost everywhere. Hayati's advantage is mostly in flavour choice and the sweet, bold style of its fruit profiles. Neither is dramatically cheaper than the other, so choose by flavour and by which device you already own.
• Vuse ePod-style closed pod systems. Vuse pods are widely available in supermarkets and convenience stores and come from a large tobacco-industry manufacturer, which some buyers like for consistency and others avoid for the same reason. The flavour range is narrower and typically leans towards tobacco and menthol. If you want fruit and candy flavours, Hayati offers more choice.
• Refillable pod kits such as Vaporesso XROS or OXVA Xlim. You fill the pod yourself from 10ml bottles of nicotine salt liquid. The cost per millilitre is much lower, and the choice of flavours is enormous, but you have to refill, handle liquid and occasionally replace coils. If you want the lowest running cost and do not mind the upkeep, this is cheaper. If you want zero fuss, prefilled pods win.
• Disposable vapes. No longer legal to supply in the UK from 1 June 2025, so they are not a real comparison. The reusable pod format is the legal, lower-waste replacement.

There are honest downsides to consider. Prefilled pods are tied to a single device family, so if the manufacturer changes the format, or the shop stops stocking it, your device could become awkward to feed. The cost per millilitre is higher than bottled liquid. And at 2ml per pod, you will be changing pods more often than you would be refilling a larger tank.

On the plus side, you get a consistent nicotine salt product, a fresh mesh coil every time, no leaking bottles in your bag and a simple routine that many smokers find helps them stay off cigarettes. For adult smokers who want a straightforward switch, that predictability is worth paying a little extra for. Buying a few pods at once also saves on delivery and means you are never caught short.
