The Hayati Pro Ultra 25000 is a rechargeable prefilled pod kit, and that fact changes every fix in this guide. It is not a sealed disposable that you throw away when it stops, and it is not a refillable kit that you fill yourself with a bottle. You keep the battery device, and you replace the whole prefilled pack when it runs out. Most faults on this kit are pack seating, contact, liquid level, charging, or airflow faults, not a dead battery device on its own.
The kit also has one feature that looks like a fault until you know it. One pack holds two flavours, and you switch between them by lifting and twisting the mouthpiece. The screen shows L or R for the side in use. A flavour that suddenly changes, or a side that seems to have stopped, is often just the mouthpiece sitting on the other side, or one refill container running low while the other still has liquid left.
This guide covers ten problems in a mixed order, starting with leaking and gurgling, then mixed flavours and one side not working, not charging, burnt taste, not firing, fast battery drain, flashing and E2, weak vapour, tight draw, and auto-firing. Each section gives causes, fixes, and a clear pack or device replacement rule, so a low refill container is not mistaken for a broken device, and a worn coil is not kept in use past its life.
Read this before you touch anything else: The Hayati Pro Ultra 25000 is a prefilled pod kit for adults aged 18 and over in the UK, with 20mg per ml (2 percent) nicotine salt liquid. Never open the battery device, never try to replace the battery, and never try to refill, pierce, or repair a sealed pod or refill container. Never charge a device that is hot, swollen, cracked, leaking heavily, or smells of burning plastic. When the checks in this guide fail, pack replacement comes first, and device replacement comes only after a fresh pack test fails. Stop using the device at once if it fires on its own, gets hot in a pocket or bag, or shows damage.
Hayati Pro Ultra 25000 at a Glance: A Rechargeable Prefilled Pod Kit, Not a Disposable
| Entity / feature | What it is on the Hayati Pro Ultra 25000 |
|---|---|
| Brand | Hayati, Pro Ultra range |
| Product | Hayati Pro Ultra 25000, also sold as Hayati Pro Ultra Plus 25000 and Hayati Pro Ultra 25k |
| Device type | Rechargeable prefilled pod kit, NOT a sealed disposable, NOT user refillable |
| Puff rating | Up to 25,000 puffs per pack, a maker rating that varies with draw length and frequency |
| Battery | 850mAh built-in, rechargeable by USB-C, with a display screen |
| Pod and refills | 2ml prefilled pod plus two 10ml refill containers, 22ml in total per pack in the most detailed listings |
| Nicotine strength | 20mg per ml (2 percent) nicotine salt, the UK maximum for this type of product |
| Coil | Mesh coil built into the pod, not replaceable on its own, replace the whole pack |
| Flavours per pack | Two flavours in a dual pack, or one flavour in both sides in a single flavour pack |
| Flavour switching | Lift and twist the mouthpiece 180 degrees to switch sides, screen shows L or R |
| Firing | Draw activated, no button to press to fire |
| Draw style | Mouth to lung (MTL) |
| Airflow | Fixed inlets on the device and pod, no wattage or airflow dial on the listings checked |
| Display | Screen showing battery level and the side in use, L or R |
| Charging cable | USB-C cable not included in the box in the listings checked, use a cable you already own |
| TPD position | 2ml pod limit, 10ml refill containers, and 20mg per ml maximum, as set out in UK rules |
The 22ml total is the figure from the most detailed listings, and from the box wording “2ml plus 2 x 10ml”. Some retailer listings give 24ml instead, by counting two 1ml pod chambers and two 10ml containers, plus a small preloaded amount, in different ways. This guide uses 22ml as the working total, and it keeps that conflict visible here rather than hiding it. The difference does not change any fix below, because every fix checks the refill container in use, not a total millilitre count.
Do not confuse this kit with the older Hayati Pro Ultra 15000. That was a single use device, and it is a different product. Do not confuse it with the Hayati Pro Max Plus 6000 either. That is a smaller single tank kit in the same range, and its packs do not fit this device. Use only packs made for the Hayati Pro Ultra Plus 25000 system, and check the device name on the pack before you buy.
Note on the Boss of Vapes listing checked for this guide: the shop lists the kit as “Hayati pro ultra 25000” in the Prefilled Pod Kit category, at a sale price of 13 pounds, down from 15 pounds. Its description gives up to 25,000 puffs, a replaceable prefilled pod, USB charging, draw activation, and 2 percent nicotine. A site search for “25k” returns no results there, because the listing uses “25000”. Search for 25000, or browse the Prefilled Pod Kit category, to find it.
Twist to Switch: How the Dual Flavour System Works
Check the mouthpiece position, the screen letter, and the refill container in use before you assume a flavour fault. On this kit, the mouthpiece, the screen, and the refill containers work as one system, so a twist can change the whole experience without touching anything else.
Twist to Switch Flavours
Lift the mouthpiece slightly, twist it 180 degrees, and it clicks over to the other side. The screen then shows the new side, L or R. That side is the flavour you will taste on the next draw. A flavour that seems to have changed on its own is often just a mouthpiece that moved in a pocket or bag, or a mouthpiece that was twisted during fitting and never twisted back. Twist it back, take a slow draw, and check the screen letter before you judge the flavour.
A dual pack puts a different flavour in each refill container. A single flavour pack puts the same flavour in both sides, so twisting makes no taste difference, and that is normal for that pack. Do not expect a flavour change from a single flavour pack, and do not judge a dual pack by one side alone, because one side can run low while the other still tastes full.
Single Flavour Packs and the L and R Screen
The screen is your quickest check. It shows battery level, and it shows L or R for the side in use. A blank screen usually means a flat battery, so charge first. A screen that shows a battery number but no draw means the pack, the contacts, or the airflow is the problem, not the screen itself. The refill containers are see through, so you can also look at the container in use and see if it is empty, even before the taste changes.
The pod is fed by the refill containers as you vape. You do not fill anything yourself, and you do not open a container to top it up. When both containers are empty, the pack is finished, even if the battery device still charges and the screen still lights up. Fit a fresh pack made for this system, remove all stickers and plugs from the new pack, push it fully home, and give it a short rest before the first draw.

Fixing the Hayati Pro Ultra 25000, One Problem at a Time
A Hayati Pro Ultra 25k can stop hitting, fail to charge, leak, flash, or taste burnt when the pack, the contacts, the refill level, the battery, or the airflow has a problem. Basic checks can help identify the cause before a pack or device replacement is needed.
Basic pack check, do this first for any problem below, unless that section tells you to stop for safety: Make sure the pack is fully seated, with no gap and no wobble, and that each refill container sits on its matching side. Wipe the pack contacts and the device contacts with a dry tissue, check the refill level in the container in use through its see through wall, charge the device fully until the screen shows a full battery, and check the screen letter for the side in use. If you have a fresh pack, test with it. If a fresh pack works and the old pack does not, the old pack is finished, even if the device is fine. On a new pack, remove every sticker, silicone plug, and hard rubber seal first, then push the pack fully home until it sits flat.

1. Why Is the Hayati Pro Ultra 25000 Leaking or Gurgling?
Leaking or gurgling on this kit often means the pack is not seated, a seal is damaged, condensation has built up in the mouthpiece, or draws are too hard and too fast. A small amount of condensation is normal in a pod system, and it is not the same as a steady leak. A steady leak, liquid on the contacts, or liquid in the mouthpiece on every draw is a pack problem, and it needs a different response.
Common Causes
- A pack not pushed fully home, so liquid can work past a seal.
- A cracked pod or refill container, or a seal damaged during fitting.
- Condensation in the mouthpiece and airflow path after long use.
- Very hard, long draws pulling liquid into the mouthpiece.
- A pack stored on its side in heat, or left in a hot car or pocket.
- A worn pack near the end of its life, with a coil that no longer holds liquid well.
- Liquid on the contacts, breaking the seal and the connection at the same time.
How to Fix
- Do the basic pack check first.
- Remove the pack, wipe the contacts and the mouthpiece with a dry tissue, and reseat the pack firmly until it sits flat. Check for cracks or a damaged seal as you do this, and do not force a cracked pack back into the device.
- Take slow, gentle draws, about two to three seconds each, with a short gap between puffs. Hard draws pull liquid up, and short gaps do not give the coil time to clear.
- Keep the device upright when you can, and store it at room temperature, away from heat and sunlight. Heat thins liquid and makes leaking more likely.
- Test with a fresh pack if leaking stays after reseating and gentle draws. If a fresh pack stays dry and the old pack does not, the old pack is finished.
When to Replace
Replace the pack if it still leaks after reseating, cleaning, and gentle draws, or if the pod or a refill container is cracked, the seal is damaged, or liquid keeps reaching the contacts. Replace the device only if a fresh pack also leaks after those same checks, and the device body or pack slot looks damaged.
2. Why Are the Flavours Mixed or Why Is Only One Side Working on the Hayati Pro Ultra 25000?
Mixed flavours, or one side that seems dead, usually mean the mouthpiece is between sides, the side in use is empty, or flavour from the last side is still in the coil. This is the most misunderstood fault on a dual flavour kit, because the device is working exactly as designed, and the user is tasting the other side.
Common Causes
- A mouthpiece twisted halfway between sides, so both flavours mix on the draw.
- A mouthpiece sitting on the wrong side, so you taste the flavour you did not expect.
- One refill container empty, while the other still has liquid, so one side gives vapour and the other gives almost nothing.
- Residual flavour in the coil after a twist, for the first few draws after switching.
- A pack not seated on one side, so one container does not feed the pod.
- A single flavour pack, where both sides taste the same by design, mistaken for a fault.
How to Fix
- Do the basic pack check first.
- Lift and twist the mouthpiece firmly until it clicks on the side you want, then check the screen letter. If the screen shows the other letter, twist again until it matches the side you want.
- Look at both refill containers. If the container in use is empty, twist to the other side, or fit a fresh pack if both are empty. Do not keep drawing on an empty side, because that gives a burnt taste.
- Take two or three slow draws after a twist before you judge the flavour. The coil needs a few draws to clear the last flavour.
- Reseat the pack if one side stays dead after a firm twist and a full charge. Push it fully home, check that each container sits on its matching side, and test both sides again.
When to Replace
Replace the pack if one side stays dead after a firm twist, reseating, a full charge, and a fresh pack test, or if both containers are empty. A pack that gives mixed flavour on every draw, even with the mouthpiece clicked firmly on one side, is also finished. Replace the device only if a fresh pack shows the same mixed or one side fault.
3. Why Is the Hayati Pro Ultra 25000 Not Charging?
Not charging on this kit often means the cable, the adapter, or the port is the problem, not the battery itself. The screen is the best guide here, because a screen that lights up during charging tells you power is reaching the device, even if the battery number rises slowly.
Common Causes
- A USB-C cable that is damaged, loose, or made for data only and not for charging.
- A weak adapter, a laptop port, or a car port that gives too little power.
- Dirt, lint, or liquid in the charging port, blocking the connection.
- A flat battery that needs a few minutes before the screen shows a charge sign.
- A damaged port or cable end, from bending or pulling the cable.
- A device that is hot, swollen, or damaged, and should not be charged at all.
How to Fix
- Do the basic pack check first, unless the device is hot, swollen, or damaged, in which case stop and do not charge it.
- Try a different USB-C cable that you know charges another device, and a wall adapter you trust. Push the cable fully home, and check the screen for a charging sign.
- Clean the port gently with a dry tissue or a soft brush, and do not insert metal objects into the port. If liquid is in the port, let it dry fully before you charge.
- Leave the device on charge for at least 15 minutes before you judge it. A very flat battery can take time to show a battery number.
- Try a different socket, and do not charge through a damaged cable or a port that feels loose. If the screen shows charging but the battery number never rises, test again with a second cable and adapter.
When to Replace
Replace the device only if it still will not charge after two known good cables, a trusted adapter, a clean and dry port, and at least 15 minutes on charge, and the screen stays blank. A pack replacement will not fix a charging fault, because the battery is in the device, not in the pack. Do not keep charging a device that gets hot during charging.
4. Why Does the Hayati Pro Ultra 25000 Taste Burnt?
A burnt taste on this kit almost always means the coil is dry, the refill container in use is nearly empty, or draws are too fast and too long for the coil to keep up. A burnt taste that appears on a new pack, on the first draws, usually means the pack was not seated, or the first draws were rushed before the coil was ready.
Common Causes
- A refill container in use that is nearly empty, so the coil has little liquid left.
- Fast, long draws with no gap, drying the coil between puffs.
- A new pack used at once, with no short rest after fitting.
- A pack near the end of its life, with a coil that has lost its clean taste.
- Drawing on an empty side after twisting, instead of the full side.
- Heat, or a pack stored in heat, changing the liquid and the coil taste.
How to Fix
- Do the basic pack check first.
- Check the refill container in use, and twist to the other side if it is nearly empty. If both sides are low, fit a fresh pack rather than drawing on a dry coil.
- Take slow draws, about two to three seconds, with a short gap between puffs. This gives the coil time to draw liquid in again.
- On a new pack, fit it fully, then wait a short time before the first draw, and start with two or three gentle draws. Rushing the first draw is a common cause of an early burnt taste.
- Test with a fresh pack if the burnt taste stays after a full side, slow draws, and a rest. If a fresh pack tastes clean, the old coil is finished.
When to Replace
Replace the pack if the burnt taste stays after switching to a full side, slow draws, a rest, and a full charge, or if the taste appears on every draw from a pack that is not new. Do not keep using a pack that tastes burnt on every draw, because a dry coil will not recover.
5. Why Is the Hayati Pro Ultra 25000 Not Firing?
Not firing, or not hitting, on this kit often means the pack is not seated, the contacts are dirty, the battery is flat, or a new pack still has a sticker or plug in place. A device that gives no vapour at all, with a blank screen, is usually a battery or seating fault, not a flavour fault.
Common Causes
- A pack not pushed fully home, so the device cannot read it.
- Dirty or wet contacts on the pack or the device, breaking the connection.
- A flat battery, with no power left for the coil.
- A sticker, silicone plug, or hard rubber seal left on a new pack.
- A refill container fitted on the wrong side, so the pack does not seat flat.
- Blocked airflow inlets, so a draw does not trigger the device.
- A damaged pack, or damage from a drop, breaking the seating even when the body looks fine.
How to Fix
- Do the basic pack check first.
- Remove the pack, check for every sticker, plug, and seal on a new pack, and remove them all. Wipe both sets of contacts with a dry tissue, and reseat the pack firmly until it sits flat.
- Check that each refill container sits on its matching side, and that the pack has no gap and no wobble. A pack that sits high is not seated, and the device will not read it.
- Charge the device fully, and check the screen for a battery number before you draw. If the screen stays blank after charging, try a second cable and adapter, as in the charging section.
- Check the visible air inlets for dust or lint, and clean accessible surfaces with a dry cloth. Do not blow into the device, and do not insert objects into its internal channels.
- Test with a fresh pack. If a fresh pack fires and the old pack does not, the old pack is finished. If no pack fires after a full charge, clean contacts, and firm seating, the device is the likely cause.
When to Replace
Replace the pack if it still will not fire after removing all seals, reseating, cleaning contacts, and a full charge, or if the pack is cracked or the contacts are damaged. Replace the device only if a fresh pack also will not fire after those same checks.

6. Why Is the Hayati Pro Ultra 25000 Battery Draining Quickly?
Fast battery drain on this kit often means draw habits, charging habits, or pack age are working against the 850mAh battery, not that the battery has failed. A battery that lasts a full day with moderate use, but only a few hours with constant long draws, is behaving normally for its size.
Common Causes
- Long, frequent draws, with little gap between puffs.
- A pack near the end of its life, forcing more draws for the same flavour.
- Charging in short bursts, so the battery rarely reaches full.
- A weak cable or adapter, giving a slow charge that looks like fast drain.
- Cold or heat, which cuts battery performance for a time.
- An ageing device, after many charge cycles, holding less charge than when new.
How to Fix
- Do the basic pack check first.
- Charge the device fully until the screen shows a full battery, using a trusted cable and adapter. Do not judge battery life from a short top up charge.
- Take shorter, slower draws, with a gap between puffs, and count how long a full charge lasts. This test tells you if drain is a habit problem or a device problem.
- Test with a fresh pack if drain stays high after a full charge and slower draws. A worn pack can push you to draw more often, and that looks like battery drain.
- Keep the device at room temperature, and avoid leaving it in a cold car or in direct heat. Temperature alone can cut a day of use to a few hours.
When to Replace
Replace the pack if drain stays high after a full charge, slower draws, and a fresh pack test, and the old pack tastes weak or burnt as well. Replace the device only if a fresh pack also drains fast after a full charge with a trusted cable, and the device is not hot or damaged. A device that gets hot during normal use should be stopped at once, as in the auto-firing section.
7. Why Is the Hayati Pro Ultra 25000 Flashing or Showing E2?
Flashing on this kit usually means the battery is low, the pack is not seated, or the contacts are dirty. E2 is a term used in some retailer guides for a pod connection fault, but Hayati does not publish an official error code list for this kit in the listings checked. Treat E2, or any flashing with no vapour, as a pack connection check first, not as a confirmed device code.
Common Causes
- A low battery, giving a flash instead of vapour.
- A pack not seated, or seated on the wrong sides, so the device cannot read it.
- Dirty or wet contacts, breaking the connection.
- A damaged pack, or a pack with a cracked seal.
- A flat battery after a long period without charging.
- Damage from a drop, breaking the pack seating even when the body looks fine.
How to Fix
- Do the basic pack check first.
- Charge the device fully, and check the screen for a battery number. If flashing stops after a full charge, low battery was the cause.
- Remove the pack, wipe the contacts on the pack and in the device with a dry tissue, and let both dry if liquid is present. Reseat the pack firmly until it sits flat, with each container on its matching side.
- Check the pack for cracks or leaks, and do not refit a cracked pack. A cracked pack can flash, leak, and damage the contacts.
- Test with a fresh pack. If a fresh pack stops the flashing and the old pack does not, the old pack is finished. If flashing stays with a fresh pack after a full charge and clean contacts, the device is the likely cause.
When to Replace
Replace the pack if flashing stays after a full charge, clean and dry contacts, and firm seating, or if the pack is cracked or leaking. Replace the device only if a fresh pack also flashes after those same checks, and the device is not hot, swollen, or damaged. Stop using a device that flashes and gets hot at the same time.
8. Why Is the Vapour Weak on the Hayati Pro Ultra 25k?
Weak vapour on this kit often means the refill level, the pack age, the airflow, or the battery is working against you, not that the device has failed. Start with the screen and the refill container in use, because those two checks settle most weak hit cases in seconds.
Common Causes
- A refill container in use that is low, so the coil has little liquid to turn into vapour.
- A pack near the end of its life, with a coil that has lost its output.
- A low battery, giving less power to the coil.
- Blocked air inlets, or a mouthpiece blocked by condensation.
- Very short, gentle draws that do not trigger a full hit.
- Cold liquid or a cold device, giving thinner vapour for a time.
How to Fix
- Do the basic pack check first.
- Check the refill container in use, and twist to the other side if it is low. If both sides are low, fit a fresh pack rather than judging vapour from a nearly empty pack.
- Charge the device fully, and take a slow draw of about two to three seconds. A short puff gives weak vapour on any MTL kit, and a low battery makes it weaker still.
- Clean the visible air inlets and the mouthpiece with a dry tissue, and check for condensation. Do not insert objects into the airflow channels.
- Test with a fresh pack if vapour stays weak after a full side, a full charge, and clean inlets. If a fresh pack gives full vapour, the old pack is finished.
When to Replace
Replace the pack if vapour stays weak after switching to a full side, a full charge, clean inlets, and slow draws, or if the pack tastes flat as well as weak. Replace the device only if a fresh pack also gives weak vapour after those same checks.
9. Why Does the Draw Feel Tight on the Hayati Pro Ultra 25000?
A tight draw on this kit often means an inlet is blocked, the pack is not seated, or condensation has narrowed the airflow path. This kit has no airflow dial in the listings checked, so a tight draw is a blockage or seating problem, not a setting you can turn.
Common Causes
- Dust, lint, or pocket debris in the visible air inlets.
- Condensation in the mouthpiece after long use.
- A pack not seated flat, narrowing the airflow path.
- Liquid on the contacts, or liquid in the mouthpiece, blocking the draw.
- A damaged mouthpiece, or a mouthpiece twisted halfway between sides.
- Cold weather, or a device used at once after coming in from the cold.
How to Fix
- Do the basic pack check first.
- Clean the visible air inlets and the mouthpiece with a dry tissue, and wipe away any condensation. Do not blow into the device, and do not insert objects into its internal channels.
- Reseat the pack firmly until it sits flat, and twist the mouthpiece firmly until it clicks on one side. A mouthpiece between sides can feel tight and give mixed flavour at the same time.
- Take a slow, steady draw, rather than a hard pull. A hard pull on a blocked inlet feels tighter, and it pulls liquid into the mouthpiece.
- Test with a fresh pack if the draw stays tight after cleaning and reseating. If a fresh pack draws normally, the old pack is finished.
When to Replace
Replace the pack if the draw stays tight after cleaning, reseating, and a firm mouthpiece click, or if the mouthpiece or pod is damaged. Replace the device only if a fresh pack also draws tight after those same checks, and the device body or pack slot looks damaged.
10. Why Is the Hayati Pro Ultra 25k Auto-Firing or Getting Hot?
Auto-firing, or a device that gets hot on its own, is a safety problem, not a normal fault to fix at home. Do not try to fix this section with cleaning, charging, or a new pack. Stop using the device, and keep it away from anything that can catch fire, until you can dispose of it safely through a proper route.
Common Causes
- Liquid or damage inside the device, triggering firing without a draw.
- A damaged battery, or a device that has been dropped, crushed, or exposed to water.
- A pack that does not fit, or a pack forced into the device, damaging the contacts.
- Heat, or a device left in a hot car, pocket, or bag, with no airflow around it.
- A fault in the firing sensor, which cannot be repaired at home.
How to Fix
- Stop using the device at once. Do not draw on it, do not charge it, and do not try to clean it while it is firing or hot.
- Move it to a safe, open place, away from bedding, clothing, and flammable items, and let it cool fully. Do not put it in water, and do not put it in a pocket or bag while it is hot.
- Remove the pack only once the device is cool and has stopped firing on its own, and only if you can do so without force. If the pack will not come out easily, leave it in place and seek advice from the seller.
- Do not refit the same pack, and do not charge the device again. A device that has auto-fired once should be treated as unsafe, even if it later looks normal.
When to Replace
Replace the device at once if it has auto-fired, or if it gets hot without use, swells, cracks, or smells of burning plastic. Do not reuse it, and do not give it to another person. Contact the seller about safe disposal, and follow local battery disposal rules. A pack replacement will not fix auto-firing, because the fault is in the device, not in the pack.
FAQS (FREQUENTLY ASKED QUESTIONS)
Why is the Hayati Pro Ultra 25000 not working?
Check the pack seating, the contacts, the battery, and the refill level first. Remove all seals from a new pack, reseat it firmly, wipe the contacts, charge fully, and test with a fresh pack if you have one. If a fresh pack works, the old pack is finished. If no pack works after those checks, the device is the likely cause.
Why is a brand-new Hayati Pro Ultra 25000 not working?
A brand-new pack often still has a sticker, silicone plug, or hard rubber seal in place, or it is not pushed fully home. Remove every seal, push the pack flat with each container on its matching side, charge the device, and start with slow, gentle draws. If it still gives no vapour, test with a second pack, because a new pack can also be faulty.
Why is the Hayati Pro Ultra 25000 pod not detected or showing E2?
This usually means the pack is not seated, the contacts are dirty or wet, or the battery is low. Wipe and dry the contacts, reseat the pack firmly, charge fully, and test with a fresh pack. Hayati does not publish an official E2 code list for this kit in the listings checked, so treat E2 as a connection check, not as a confirmed device fault.
How do you switch flavours on the Hayati Pro Ultra 25000?
Lift the mouthpiece slightly, twist it 180 degrees until it clicks, and check the screen letter. L is one side, R is the other side. Take two or three slow draws after a twist before you judge the flavour, because the coil needs a few draws to clear the last flavour.
Can you refill the Hayati Pro Ultra 25000 pods?
No. The pods and refill containers are sealed and prefilled, and they are made to be replaced, not opened or topped up. Opening a pod can damage the coil, cause leaking, and break the seal. When both refill containers are empty, fit a fresh pack made for this system.
How long does it take to charge the Hayati Pro Ultra 25k?
The listings checked do not give a single official full charge time for this kit. Charge with a trusted USB-C cable until the screen shows a full battery, and do not judge charging from a short top up. If the screen shows charging but the battery number never rises after a second cable and adapter, the device is the likely cause.
Why does the Hayati Pro Ultra 25k taste weak or burnt?
A weak taste usually means a low refill container, a worn pack, or a low battery. A burnt taste usually means a dry coil, an empty side, or fast, long draws with no gap. Twist to a full side, take slow draws with a gap, and fit a fresh pack if the taste stays weak or burnt after those checks.
How many puffs does the Hayati Pro Ultra 25000 give?
Up to 25,000 puffs per pack, as a maker rating. Long, frequent draws give fewer puffs, and short, gentle draws give more. Judge a pack by flavour, vapour, and refill level, not by a puff count alone, because the rating is measured on machine draws.
What pods work with the Hayati Pro Ultra 25000?
Use only packs made for the Hayati Pro Ultra Plus 25000 system. Packs for the Hayati Pro Max Plus 6000, other Hayati models, or other brands do not fit this device, and forcing a wrong pack can damage the contacts and cause leaking. Check the device name on the pack before you buy.
How should you store the Hayati Pro Ultra 25000?
Store the device and spare packs upright, at room temperature, away from heat, sunlight, and damp. Keep the device out of pockets with keys or coins, and keep spare packs sealed until use. Do not store a device that is hot, swollen, cracked, or leaking, and follow local battery disposal rules for a damaged device.
