Overview of the Hayati Pro Max Plus 4000 Grape replacement pods

The Hayati Pro Max Plus 4000 Replacement Pods in Grape (GB edition) are prefilled, ready-to-fit pods made for the Hayati Pro Max Plus 4000 device. Rather than buying a whole new vape every time the liquid runs out, you keep the rechargeable body and swap only the pod. That makes this a pod-refill product, not a standalone vape: the pods do nothing without the matching Hayati hardware, and they are not designed to be fitted to other brands' devices.

Hayati is a name most UK vapers know from its disposable-style and rechargeable ranges, and the Pro Max Plus line is its swappable-pod format. The GB tag in the product name tells you this is the edition prepared for the British market. That matters for practical reasons: the nicotine strength and pod capacity are set to the limits UK rules allow, and the packaging carries the health warnings and information that UK buyers are expected to see.

The 4000 in the name is the brand's rated puff count. We treat that as a headline rating rather than a promise, and the sections below explain what actually influences how long a pod lasts in daily use. Grape is a fruit-led flavour with a sweet, juicy character, aimed at vapers who prefer something closer to a fruit drink or confectionery than to tobacco or menthol.

This guide is written to help you decide whether these pods fit the way you vape, and to help you get good results from them if you already own the device. It covers:

• what the pack contains and how the pod system works
• the grape flavour profile on the inhale and exhale
• real-world puff delivery and what shortens or extends pod life
• build quality, battery and charging, and the coil
• nicotine strength and UK rules
• who the pods suit, how to fit and store them, and what to do when something goes wrong
• value for money and how the pods compare with other options

Important: vaping products containing nicotine are for adults aged 18 and over only. Nicotine is addictive. If you do not currently smoke or vape, please do not start.

What is in the pack and how the pod system works

Pod systems like the Pro Max Plus split a vape into two parts. The device holds the rechargeable battery and the electronics that fire the coil. The pod holds the e-liquid, the wick and the coil in a single sealed unit. When the pod is empty, you remove it and click in a fresh one. This listing covers the pod side of that arrangement only.

Because the pods arrive prefilled, there is no pouring, no bottle to carry and no risk of overfilling the reservoir. This is usually described as a closed pod system, in contrast to an open pod kit where you fill the pod yourself from a bottle. The trade-off is simple: closed pods are quicker and tidier, while open kits generally cost less per millilitre over time and give you a wider choice of liquid.

A few points are worth checking before you order:

• Device match. These pods are made for the Hayati Pro Max Plus 4000. Hayati sells several pod-style products, and pods are not automatically interchangeable across the range. Match the model name exactly rather than assuming that any Hayati pod will fit.
• Pack quantity. The listing shows how many pods come in each pack. Divide the price by the number of pods to get your cost per pod, which is the number that matters when you compare with other options.
• What is not included. The device body and charging cable are not part of a replacement pod pack. If you have not bought the device yet, you need that first.
• Flavour variant. This page is for Grape only. Other Hayati flavours are listed as separate products, and a pod's flavour is fixed when it is filled, so you cannot change the flavour of a pod after purchase.

Inside the pod, the e-liquid is a nicotine salt formulation. Nic salts use a form of nicotine that feels gentler on the throat at higher strengths than the older freebase style, which is why almost every compact pod device sold in the UK uses them. The liquid is drawn through a cotton wick to the coil whenever you inhale, so a short wait after fitting a new pod gives the wick time to soak. The fitting steps are set out in order in the how-to-use section further down.

Under UK rules, a prefilled pod cannot hold more than 2ml of e-liquid. That limit is part of why replacement pods are sold in packs and why the device is built to be reused: the hardware is designed to last across many pods rather than being thrown away with the first one.

Grape flavour profile: inhale, exhale and aftertaste

Grape is a familiar fruit flavour in vaping, but vape grape rarely tastes like a bunch of fresh grapes from the fridge. The usual interpretation is closer to purple grape confectionery: a rounded, sweet, juice-style fruit with a hint of the candy or soft-drink character that people associate with grape-flavoured sweets. If you expect that style, you are unlikely to be surprised.

Flavour is personal, and we are describing a profile rather than a laboratory reading, so treat the notes below as a guide to what this flavour family typically delivers:

• Inhale: sweet grape up front, with a smooth, juicy body. The nicotine salt base keeps the throat feel soft, so the fruit comes through before any warmth or throat hit.
• Exhale: the sweetness lingers and rounds out, often with a faint tartness that stops the flavour feeling flat. This is where a grape profile shows whether it has some depth or is only sugar.
• Aftertaste: a light, sugary grape note on the tongue. The product name does not advertise a cooling or ice element, so do not expect a menthol chill. Treat it as a straight fruit flavour.

Grape tends to suit vapers who find berry blends too sharp and who want a mellow, easy-going flavour they can use through the day. It also suits people moving away from cigarettes who want a taste that is clearly different from tobacco, because a distinctly fruity flavour helps break the association between the habit and the old taste.

A few things influence how the flavour comes across in practice:

• Draw length. Slow, steady draws of two to three seconds let the coil vaporise the liquid evenly. Very long or very hard draws can heat the coil too quickly and flatten the fruit notes.
• Pod level. As the pod empties, the flavour can thin slightly and become warmer. That is a sign the pod is nearing its end, not a sign that the recipe has changed.
• Palate fatigue. Sweet flavours can seem to fade if you vape one flavour continuously for long periods. A drink of water or a break of a few minutes usually restores the taste.
• Temperature. Cold weather thickens e-liquid slightly, which can make the first few draws taste muted. Keeping the device in an inside pocket helps.

Flavour consistency is one of the genuine advantages of a prefilled pod. Each pod is filled in the factory with the same formulation, so your second pack should taste like your first. If a pod tastes clearly different from the previous one, check the troubleshooting section before assuming you have a bad batch.

Puff count and real-world performance

The headline figure is 4000 puffs, which is how the brand rates this product. Puff ratings are normally derived from machine-puffing tests, in which a machine takes a fixed-length draw at set intervals. Real people draw differently: longer, shorter, harder, softer and at irregular gaps. That is why two vapers can get quite different lifespans from exactly the same pod.

The UK limit on pod size is also relevant. Pods sold in Great Britain cannot hold more than 2ml of e-liquid, so a rating this high should be read as a ceiling reached under test conditions, not a number to plan your week around. Check the listing for how the pack is described, and expect real use to land below the headline.

As a simple planning exercise, if you took around 150 puffs a day, a 4000 puff rating would work out to just under four weeks. At 300 puffs a day it would be closer to two weeks. Long draws, frequent top-up puffs and chain vaping all shorten that; light, occasional use stretches it. We suggest measuring your own first pod by noting the day you fit it and the day the flavour fades, then using that figure to work out how many pods you need each month.

On the draw itself, pod systems of this kind are generally built around a tight-to-medium restricted draw, closer to drawing on a cigarette than to the open, airy pull of a larger sub-ohm tank. Vapour production is moderate rather than cloud-heavy, which is a deliberate design choice for compact devices and for UK nicotine limits.

• Activation. Devices in this class usually fire when you inhale, with no button to press. Check the guide that comes with your device if you are unsure.
• Ramp-up. A mesh-style coil heats quickly, so flavour is usually present from the first puff after the pod has primed.
• Throat hit. Nic salts at 20mg/ml give a noticeable but smooth throat hit. If you are used to low-strength freebase, the first few days can feel stronger than you expect.
• Consistency. Output should stay steady through most of the pod's life and then fade towards the end.

Signs that a pod is running down include a warmer vapour, a flatter flavour and a slightly harsher throat feel. When you notice these, replace the pod instead of continuing, because pushing a nearly empty pod can scorch the wick and leave a burnt taste.

Pod design and build quality

The pod is a compact, sealed plastic cartridge that clicks into the top of the device body. Its job is to keep the liquid, wick and coil together in a leak-resistant package, and how well it does that is the practical measure of build quality in a pod system.

Here is what to look for when your pods arrive:

• Intact seal and wrapper. The pod should be sealed, with no sign of liquid on the outside of the wrapper. A damp wrapper suggests damage in transit; photograph it and contact us with your order number.
• Clean contacts. The metal contacts on the base of the pod, and the matching ones on the device, should be dry and free from residue so the device can detect the pod and fire the coil.
• A firm click. A well-made pod seats with a clear click and no wobble. A pod that rocks or sits proud of the device body is not fully seated.
• Visible liquid level. Many pods have a window or translucent wall so you can see how much e-liquid remains instead of guessing from flavour alone. Check the product images to see how this pod presents.

The mouthpiece is shaped for a comfortable fit between the lips and is moulded as part of the pod, so it is replaced every time you change pods. That is a small hygiene advantage over a device where one mouthpiece stays in use for months.

As with any plastic-bodied compact device, impact is the main enemy. A pod dropped onto a hard floor can crack at the seams or loosen the seal, which leads to leaking. If you carry the device loose in a bag or a pocket with keys, a simple case is worth having. The format is designed for pocket carry, but pocket carry means pressure and body heat.

Leaks in closed pods usually come from pressure and temperature changes rather than from a manufacturing fault. Flying is the classic example: air inside the pod expands at altitude and can push liquid out. Keep the device upright, avoid leaving it in a hot car, and do not store it upside down with a full pod. If liquid does escape, wipe the contacts with a dry tissue before refitting the pod.

Overall, build quality in this class is about sensible tolerances and a good seal rather than premium materials. Judge a pod by how securely it seats, whether it stays dry in storage, and whether it delivers steady output across its life.

Battery and charging: what to expect from the device

The battery lives in the device, not the pod. That distinction is important: when you replace a pod you are not replacing the battery, which continues to age at its own pace. The pod is a consumable; the battery is a component with a limited number of charge cycles.

Devices in this class typically carry a battery in the region of 500 to 650mAh and charge over USB-C. We would rather point you to the specification printed on your own device's box than state a single figure that might not match every production batch. The thing to understand is capacity relative to pod size: a battery of this size is a modest one, sized to suit a small pod.

The practical consequence is that, depending on how you vape, one charge may not cover a whole pod. Charging once or twice per pod is normal for a compact device and is not a fault. If the battery runs flat before the pod is empty, that does not mean the pod is defective.

Charging habits that keep the battery healthy:

• Use the USB-C cable supplied with the device, or a good-quality replacement, with a standard 5V adapter or a computer USB port. Avoid unbranded, unusually cheap chargers.
• Expect a full charge to take roughly an hour for a device of this size. Check the indicator light behaviour described in your device guide.
• Do not leave the device charging unattended for long periods, and never charge it on a bed, sofa or other soft surface.
• Keep it away from heat. A car dashboard in summer is a poor place to store any lithium battery.
• Top-up charges are fine for lithium cells. You do not need to run the battery to zero before recharging.
• If you will not use the device for several weeks, store it at around half charge in a cool place.

Stop using the device if it becomes unusually hot, swells, hisses or smells of burning. Move it to a non-flammable surface away from other items and take it to a recycling point; do not keep charging it.

Over many months, battery capacity falls gradually, and the device will need charging more often. That is normal ageing. When the device no longer lasts through a day, or fails to hold a charge, it is time to replace the device rather than keep buying pods for tired hardware.

Coil and mesh technology inside the pod

The coil is the heating element that turns liquid into vapour, and in a closed pod it is built into the pod itself. Hayati pods in this range are described by the brand as using a mesh-style coil. We recommend confirming the coil type on the pack you receive, since manufacturers sometimes update components between production runs.

A mesh coil replaces the familiar round wire wound into a spiral with a flat or curved sheet of fine metal mesh. The potential benefits are practical rather than dramatic:

• Wider heating surface. A larger surface touches more of the wick at once, so heat is spread across a bigger area. That can help flavour feel more even from puff to puff.
• Fast ramp-up. Mesh warms quickly, so you get flavour almost as soon as you start to inhale.
• Fewer hot spots. With heat distributed more evenly, the chance of localised scorching is lower than on a small wire coil, provided the wick stays wet.

Resistance for nic salt pods generally sits around the one ohm mark, though the exact figure is not something you need to manage because the device is matched to the pod. The device reads the pod through its contacts and fires the coil at a set output. You cannot adjust wattage in a closed system, and that is by design: the pod and device are tuned together to give a consistent result.

The coil is wrapped in organic cotton or similar wicking material, which draws liquid from the reservoir by capillary action. The wick needs to be saturated before you start vaping. If you fire the coil while the wick is still dry, the cotton can scorch, and a scorched wick leaves a burnt taste that does not recover. This is why we recommend the short priming wait described in the how-to-use section.

Because the coil cannot be replaced separately, its life is the same as the pod's life. Several habits help it last:

• Take steady draws rather than very long ones, and give the coil a few seconds between puffs.
• Avoid vaping a pod that is nearly empty.
• Keep the device upright between uses so the wick stays fed.
• Do not blow into the mouthpiece to clear it, since that can push liquid back into the airflow path and flood the coil.

When flavour starts to fade or taste burnt, the coil has reached the end of its useful life. The fix is simply a fresh pod.

Nicotine strength guidance and UK rules

In the UK, nicotine e-liquid is capped at 20mg/ml (2%). That cap applies to every nicotine vape sold legally here, including the rechargeable pod products that replaced single-use vapes after the sale of disposables was prohibited in Great Britain from 1 June 2025. Alongside the strength cap, prefilled pods and tanks are limited to 2ml, and refill bottles to 10ml.

GB-edition Hayati pods are usually supplied at the 20mg/ml ceiling, but please confirm the strength shown on the variant you select, since packs and strengths can change. If a lower-strength version is offered, the strength will be stated on the listing.

What does 20mg/ml actually mean in practice? It is the nicotine-salt strength most closely matched to the speed and satisfaction of smoking a cigarette, which is why it is the most common choice for people who have recently stopped smoking. The important point is that nic salt at 20mg/ml feels smoother than freebase nicotine at the same strength, so it can be taken in without the harshness you might expect.

As a rough guide to who benefits from a higher strength:

• Smoking 10 or more cigarettes a day: a 20mg/ml strength is often needed to feel satisfied early in the switch. Under-dosing leads to frequent puffing and a return to cigarettes.
• Smoking fewer than 10 a day, or lighter vaping: a 10 to 12mg/ml strength, where available, can be enough and may feel gentler.
• Social or occasional smokers: a high strength may feel too strong. Consider a lower option or talk to a stop-smoking adviser.

Because a closed pod fixes the strength, you cannot dilute or adjust it once you have bought it. If you find 20mg/ml too strong, take shorter, gentler puffs, or look for a lower-strength alternative rather than continuing with a strength that makes you feel unwell. Signs that the strength is too high include dizziness, nausea, a racing heart and headache.

These pods are not for non-smokers. Nicotine is addictive and high-strength salts deliver it quickly. If you have a heart condition, are pregnant or breastfeeding, or take regular medication, speak to a pharmacist or GP before using any nicotine product. Many local stop-smoking services also offer free support alongside vaping.

Who these pods are for, and who should skip them

No product suits everyone, and a straight answer saves you money. Here is how we would sort buyers.

These pods are a good fit for:

• Existing Pro Max Plus 4000 owners. If you already have the device, replacement pods are the most direct way to keep using it. You do not need to buy a new body each time.
• Adult smokers switching to vaping. The 20mg/ml nic-salt strength and tight-to-medium draw are well matched to people replacing a cigarette habit who want simple, no-fuss hardware.
• Fruit-flavour vapers. If you enjoy sweet, juice-style flavours and want a grape option without mixing your own, a prefilled pod makes that effortless.
• People who value tidiness. There is nothing to fill, no bottle to carry and no spills, which suits commuting and travel.

You may want to look elsewhere if you are:

• Under 18. Sales of vapes to anyone under 18 are illegal in the UK. We do not sell to minors.
• A non-smoker. Nicotine vapes are intended for adult smokers who want to move away from tobacco, not as a starter product.
• After adjustable settings. If you want to change airflow or wattage, a variable-power refillable pod kit will give you that control. This is a fixed, closed system.
• Looking to refill your own liquid. These pods are not designed to be refilled, and attempting to do so is unsafe and can damage the coil.
• A big-cloud vaper. The draw and vapour output are tuned for compact, discreet use rather than for large clouds.
• Someone who dislikes sweet flavours. If you prefer tobacco or mint, a different flavour from the same pod range will serve you better than grape.
• Without the matching device. The pods only work in the Hayati Pro Max Plus 4000. Without it, you will need to buy the device too.

If you are unsure whether you fall on one side or the other, start with a single pack rather than a bulk order. Use the first pod to find out how long it lasts for your puffing style and whether the flavour holds up for you over several days. That small test costs little and saves a lot of waste if the format is not right.

Finally, if your goal is to stop smoking, remember that vaping works best when you stop smoking completely rather than doing both. Dual use delivers less benefit than switching fully.

How to fit, use, store and recycle the pods

Fitting a replacement pod takes under a minute. Follow the steps in order and you will avoid the most common causes of burnt taste and leaks.

• 1. Check the device. Make sure the battery has some charge and that the contacts are dry and clear.
• 2. Unwrap the pod. Remove any outer wrapper and protective plugs or film from the pod. Check that the mouthpiece and the base are free of damage.
• 3. Seat the pod. Push the pod into the device in the correct direction until you feel and hear a click. It should sit flush without wobbling.
• 4. Let it prime. Wait about a minute with the device upright so the liquid can saturate the wick.
• 5. Take gentle first puffs. Start with two or three soft draws to pull liquid onto the coil, then move to normal use.
• 6. Vape at an easy pace. Steady two to three second draws are enough. Pause between puffs.

Storing and carrying. Keep the device upright where you can, away from heat and direct sunlight, and out of reach of children and pets. Carry spare pods in their packaging so the contacts and seals stay clean. Avoid keeping them in a pocket with coins or keys.

When to change the pod. Replace it when the flavour fades, the vapour turns warm or harsh, or you can see the liquid level is very low. Do not wait until it tastes burnt.

Removing a used pod. Pull the pod straight out; do not twist. Hold it upright and avoid squeezing the sides so any residue stays inside. Wipe the device contacts lightly with a dry tissue before fitting the next pod.

Recycling in the UK. Used pods contain a coil and residual nicotine, and the device contains a lithium battery. None of this belongs in household bins or kerbside recycling. Waste vapes and pods count as small electrical waste, so take them to a retailer take-back point, a household waste recycling centre or a dedicated vape recycling bin. Many shops that sell vapes are required to accept used products, and your council website will list local drop-off points. Putting a lithium battery into general waste is a genuine fire risk for bin lorries and recycling plants.

Safety basics. Keep nicotine products away from children and pets. If liquid gets on your skin, wash it off with soap and water. If a child or animal swallows any, seek urgent medical or veterinary advice and keep the packaging to show them.

Troubleshooting common pod problems

Most problems with replacement pods have simple causes. Work through the likely ones before deciding that a pod is faulty.

• No vapour or the device does not respond. Check the battery level first. Then remove the pod, wipe both sets of contacts with a dry tissue and refit it until it clicks. If the pod has just been fitted, give it a minute to prime and try again with a gentle draw.
• Burnt or acrid taste. This usually means the wick has dried out, either because the pod is nearly empty or because you fired it too hard before it primed. Replace the pod. Taking long, repeated draws is a common cause; shorter puffs with gaps help.
• Weak or muted flavour. Cold temperature, palate fatigue and an almost empty pod all produce this. Warm the device in your hand, rinse your mouth with water, and check the liquid level before concluding the pod is dull.
• Gurgling or spitting. Condensation has gathered in the airflow path. Hold the device upright, and take a couple of quiet draws away from your mouth to clear the airflow. Do not blow back into the mouthpiece.
• Leaking from the base. Check that the pod is fully seated and dry. Leaks often follow heat, pressure changes or being stored on its side. Wipe off any liquid and keep the device upright. If a new pod leaks straight out of the wrapper, contact us.
• Device flashes or will not recognise the pod. The usual cause is a poorly seated pod or dirty contacts. Remove, wipe and refit. Flashing can also indicate a low battery or a short-circuit protection; the device guide lists what each pattern means.
• Battery drains quickly. A compact battery runs down in a day or two of heavy use, and it ages over many months. Check your charger and cable before assuming a fault.
• Sticky residue on the mouthpiece. This is normal condensation from sweet e-liquid. Wipe the mouthpiece with a damp cloth and let it dry. Never rinse the pod under a tap, since water can reach the coil.
• Throat irritation or coughing. This often relates to strength, draw length or dehydration. Try shorter puffs and drink more water. If the irritation continues, stop using the product and speak to a pharmacist.

If none of this helps, keep the pod, its packaging and your order number, and contact our customer service team with a clear description and photographs. A genuine fault is something we will want to look at, and it helps us improve our stock checks. Please do not try to open or repair a pod yourself.

Value for money and how the pods compare

The honest way to judge value is cost per day, not cost per pack. Take the price of the pack, divide it by the number of pods inside, and then divide by the number of days a single pod lasts for you. That gives you a daily running cost you can compare directly with cigarettes, other pod systems or open kits.

Where closed pods tend to win is convenience. You do not buy bottles, tools or spare coils, and the flavour is consistent. Where they tend to lose is cost per millilitre, because you pay for the sealed cartridge as well as the liquid. Here is a fair look at the alternatives.

• Refillable pod kits. Open systems from brands such as Vaporesso and OXVA cost less to run over time, since 10ml bottles of nic salt are cheap and coils are inexpensive. They also let you pick from a huge range of flavours and strengths and often offer adjustable airflow. The cost is a bit of mess, more to carry, and a learning curve. If you do not mind filling a pod, they are often cheaper per month.
• Other prefilled pod systems. Closed-pod products such as Vuse ePod are widely stocked in supermarkets and corner shops and come from large manufacturers with established support. Their flavour ranges are often narrower, and some use lower maximum strengths. Hayati's draw is a wider spread of fruit and dessert profiles, so if you want grape in particular, this pod is more likely to have it.
• Single-use vapes. These are no longer legal to sell in Great Britain, so they are not a realistic comparison any more. Rechargeable systems such as this one produce far less waste.
• Nicotine replacement therapy. Patches, gum and inhalators have clinical backing and can be free through NHS stop-smoking services. They are not a taste or habit replacement, but they are worth considering alongside or instead of vaping.

On the plus side, this pod is a straightforward, familiar format with a pleasant, mellow flavour, a decent claimed puff count and a device that can be reused. On the minus side, you are locked into one device, the strength is fixed, you cannot adjust anything, and cost per millilitre will be higher than with an open kit.

Practical ways to keep costs down: buy a multi-pack where one is available instead of single packs, keep the device upright and clean so pods do not leak, avoid chain vaping, and record how long your first pod lasts so you do not over-order. Check the listing for current pack options.

Our verdict is simple. If you already own the Pro Max Plus 4000, enjoy sweet grape and want the least fuss, these pods are a sensible purchase. If you are price-driven and happy to refill, a refillable pod kit will likely cost you less in the long run. Neither is wrong; it depends on whether you value convenience or running cost more.
