Hayati Pro Ultra Plus 25000 Review: Features, Performance & Buyer Guide
High-capacity kits are hard to judge from a spec sheet, because the headline number tells you almost nothing about how a device behaves after a fortnight. This review of the Pro Ultra Plus 25000 kit, supplied as a box of five, sticks to what Hayati actually specifies and what the format means in daily use.
If you want the shorter buying-decision version instead, there is our closer look at how the device performs day to day. This piece goes further into the mechanics and the ordering side.
What 25,000 puffs actually means
The figure is a manufacturer rating based on short, light draws. Longer, warmer draws vaporise more liquid each time, so a real-world total will be lower. It still outlasts a small pod device by a wide margin, but treat it as a capacity indicator rather than a promise.
The more useful question is how a device reaches that number at all, because UK rules cap a nicotine-containing pod at 2ml.
How the format works. UK regulations limit a nicotine pod or tank to 2ml, and a nicotine e-liquid container to 10ml. High-capacity kits are engineered around those limits rather than around them: the pod holding the coil stays at 2ml, and separate 10ml reservoirs feed it as you vape. Hayati specifies this device's configuration as 2 + 2 × 10ml. This is how the category is described across the UK trade; for a definitive position on any specific product, MHRA notification records and Trading Standards guidance are the sources to check, not a retailer's description.
The duo tank and how flavour switching works
Most pod kits make you finish one flavour before starting another. The Pro Ultra Plus uses Hayati's duo-tank format: two compartments, each with its own coil, inside one device.
A twist of the mouthpiece changes which side is active. There is no electronic valve involved, which is why the two liquids stay separate rather than blending. The practical benefit is that the side you are not drawing on is not sitting on a hot coil, so it is not slowly degrading while you use the other one.
If you are weighing this against other devices in the same family, there is more detail on how the dual-tank format compares across the 25K range.
Battery, display and charging
Hayati specifies an 850mAh rechargeable battery with a smart battery display and a transparent tank, so both charge level and remaining liquid are visible without guessing.
That combination is the main day-to-day difference from an older single-use bar, where you found out it had run down mid-draw. Here you get warning, which in practice means charging on your own schedule rather than the device's.
Charge it from a standard low-power USB-C port. High-output fast-charging blocks are not what a small cell like this is designed around, and using one is the most common cause of a device that seems to stop charging properly.
Living with it day to day
The draw is mouth-to-lung, close to the pull of a cigarette, which is what most people moving across from smoking or from older bars are looking for. It is not built for large clouds and does not try to be.
Because each side has its own coil rather than sharing one, flavour stays more consistent across the life of a pod than it does on single-coil kits attempting the same two-flavour trick. The vapour is warm rather than harsh at 20mg nic salt.
On leaks: this is a sealed prefilled pod format, not an open tank you fill yourself. That design removes the main source of mess associated with refillable kits, which is spillage during filling.
Flavours and replacement pods
Hayati lists 45 flavour options across the wider Pro Ultra+ range, covering both single profiles and paired combinations. Not all of them are stocked at once, so the flavour selector on the product page is the live availability list rather than the manufacturer catalogue.
When a pod is spent you replace the pod, not the device. Matching replacement pods for this device are sold separately, and the wider range of spare pods by the pack covers the rest of the Hayati line-up.
Pods are model-specific and will not cross over between Hayati devices. If there is any doubt, which pods fit which Hayati device sets it out model by model — this is the single most common ordering mistake in the range.
Common issues and how to avoid them
Weak flavour or a dry hit
- Rapid consecutive draws outrun the wick. Leave roughly ten seconds between pulls.
- A new pod needs to soak. Fit it, leave it standing a minute or two, then start slowly.
- If the taste has turned faint or burnt and stays that way, the pod is finished rather than faulty.
Charging that appears to stall
- Use a standard low-power USB-C port rather than a fast-charge block.
- Keep the charging contacts clean and dry.
- The battery base is the part you keep. Only the pod is a consumable.
Choosing a flavour you will actually finish
Menthol and dual-ice combinations suit anyone wanting a colder throat hit; berry and mixed-fruit profiles suit sweeter preferences. Because the device runs two sides at once, pairing one of each is a reasonable way to avoid getting bored of a single profile halfway through.
For retailers stocking it
The Pro Ultra Plus is supplied five units per display box, which makes it a defined trade pack rather than a single-unit line. The commercially useful point is that the device and the pod are separate purchases: a customer starting on the system needs the complete kit, while an existing owner only needs pods.
Stocking both sides of that together avoids the most frequent counter problem, which is a customer sent away because only one half of the range is on the shelf. The wider Hayati prefilled pod kit range and the broader prefilled and reusable pod kits collection show what else sits alongside it.

Should you buy the Hayati Pro Ultra Plus 25K?
It suits steady, daily use where capacity and the two-flavour system are worth having. If you vape lightly, or you know you will run the same flavour for months, you are paying for a system you will not use — a smaller single-tank kit does the same job.
What it does well is remove the two irritations of the format it replaced: not knowing when the device will die, and having to buy a whole new device each time.
Frequently asked questions
How does a 25,000-puff kit stay within the UK 2ml limit?
UK rules cap a nicotine pod at 2ml and a nicotine e-liquid container at 10ml. High-capacity kits are built to those limits: the pod holding the coil stays at 2ml and separate 10ml reservoirs feed it during use. Hayati specifies this device as 2 + 2 × 10ml. For a definitive position on any specific product, check MHRA and Trading Standards sources rather than retailer descriptions.
Is a charging cable included in the box?
Hayati's specification does not list a cable with the display box. Most people already own a USB-C cable, but it is worth confirming before assuming one is supplied.
Why does the charger you use matter?
High-wattage fast-charge blocks are designed for larger cells than this. Using a standard low-power USB port is gentler on the battery and avoids the charging faults that get reported most often.
Do you need a whole new kit when the pod runs out?
No. The rechargeable base stays with you and only the pod is replaced. Replacement pods have their own listing, so the repeat purchase is the consumable rather than the device.
What is the correct way to set it up on day one?
Remove any transit stickers and seals, fit the pod, then let the device stand upright for a couple of minutes before the first draw. That soak period is what prevents a burnt first taste.
How does the twist mouthpiece swap flavours without mixing them?
It is a mechanical swivel rather than an electronic valve. Pull the tip up slightly, rotate, and click it down to change the active side. The two compartments stay physically separate throughout.
Is 20mg nicotine salt harsh for someone who has just stopped smoking?
Nic salts are formulated to be absorbed quickly while staying smoother than freebase nicotine at the same strength, which is why 20mg is the common choice for people moving across from cigarettes rather than a sign of harshness.
