The Hayati Pro Ultra Plus 25K is the flagship high-puff prefilled pod kit from Hayati, offering 25,000 puffs per device alongside a dual-flavour twist system and a real-time LCD display. In a UK market still adjusting to the single-use vape ban that came into force in June 2025, the Hayati 25K has emerged as one of the most talked-about rechargeable alternatives - and for good reason.
This guide covers everything you need to know: technical specifications, how the dual-flavour system works, a full breakdown of cost versus smoking and versus standard disposables, the complete flavour range, and honest answers to the questions most vapers ask before buying. Whether you are switching from cigarettes, upgrading from a 600-puff bar, or comparing the Hayati 25K against competitors like the RandM Tornado 9000, this review has you covered.

Design and Build Quality
The Hayati Pro Ultra Plus 25K has a premium feel that sets it apart from the standard prefilled pod market. The body is compact and ergonomic, designed to sit comfortably in the hand during extended use. The matte finish resists fingerprints and the overall construction feels solid rather than hollow.
The device ships pre-assembled with both flavour pods installed. There are no buttons to press - the draw-activated mechanism fires the moment you inhale, making it one of the most straightforward high-puff devices to use. The USB-C port sits at the base of the device, a practical placement that means you can charge it upright on a desk without the cable getting in the way.
Weight is noticeably heavier than a standard 600-puff bar, which is to be expected given the larger battery and dual-liquid system. Most users find the weight reassuring rather than inconvenient.
The Dual-Flavour Twist System Explained
The defining feature of the Hayati pro ultra plus is the twist mouthpiece. No other 25K puff device in the UK market offers this. Here is how it works:
- Two pods, one device. Each kit contains two separate 2ml prefilled pods, each with a different flavour. Both are installed in the device from the start.
- Twist to switch. Rotate the mouthpiece 180 degrees to switch from Flavour A to Flavour B. The switch is instant - no residual taste from the previous flavour after the first few puffs.
- Independent tracking. The LCD display shows the active flavour pod's remaining puffs, so you always know which flavour is running lower.
- No cross-contamination. The two liquid channels are completely separate inside the device. Switching flavours does not mix the two liquids.
Dual-flavour combination kits (such as Watermelon Bubblegum / Strawberry Bubblegum, or Blueberry Cotton K / Raspberry Cotton K) are the most popular configurations. Single-flavour kits are also available for vapers who prefer consistency.

LCD Display and Smart Features
The Hayati 25K LCD display shows two pieces of information in real time:
- Puff count remaining - counts down from 25,000. You can see at a glance how much life is left in the device.
- Battery level - displayed as a percentage indicator so you know when to plug in before the device dies mid-session.
The display also indicates which flavour pod is active, using a small indicator that switches when you twist the mouthpiece. This level of feedback is genuinely useful and not a gimmick - competitors like the RandM Tornado 9000 and Lost Mary BM600 offer no display at all, leaving users to guess how much liquid remains.
The smart chip also regulates power output to maintain consistent vapour production across the device's lifespan, preventing the drop in flavour quality that is common in cheaper prefilled kits as the liquid runs low.
Battery Life and Charging
The 850mAh battery is sized appropriately for the device's intended use pattern. It will not last 25,000 puffs on a single charge - that would require an impractically large battery. Instead, the device is designed to be topped up regularly via USB-C, much like a phone.
In practice, most moderate users (around 200-300 puffs per day) will charge the device every 2-3 days. The fast-charge USB-C implementation means a full charge takes under an hour, so topping up overnight or at a desk is straightforward.
The device will not fire when the battery is critically low, and the LCD display gives enough warning to charge before reaching that point. This is a meaningful advantage over standard disposable bars, which simply stop working without warning.
Cost Breakdown: Hayati 25K vs Smoking vs Disposables
One of the strongest arguments for the Hayati pro ultra 25k is cost efficiency. Here is how it compares:
| Product | Puffs | Price | Cost per 100 puffs |
|---|---|---|---|
| Hayati Pro Ultra Plus 25K (2 for £18) | 25,000 | £9.00 each | £0.036 |
| Hayati Pro Ultra Plus 25K (single) | 25,000 | £10.99 | £0.044 |
| RandM Tornado 9000 | 9,000 | £8.49 | £0.094 |
| Lost Mary BM600 | 600 | £3.80 | £0.63 |
| Standard 20-pack cigarettes | Approx. 200 puffs equivalent | ~£12.00 | £6.00 |
The cost per 100 puffs with the Hayati 25K on the 2-for-£18 deal is £0.036. That is 17 times cheaper than a standard Lost Mary BM600 and over 160 times cheaper than cigarettes on a like-for-like puff basis.
For a moderate user taking 300 puffs per day, a single Hayati 25K device lasts approximately 83 days. At £10.99, that works out to around £1.32 per week - far below the cost of any alternative. The NHS recommends vaping as a tool to help smokers quit, and independent research from Action on Smoking and Health (ASH) shows that switching fully from cigarettes to vaping significantly reduces exposure to harmful chemicals.
How Long Does the Hayati 25K Last?
| Usage level | Puffs per day | Estimated device life |
|---|---|---|
| Light user | 100 | ~250 days (8+ months) |
| Moderate user | 300 | ~83 days (almost 3 months) |
| Heavy user | 500 | ~50 days (7 weeks) |
| Very heavy user | 800 | ~31 days (4 weeks) |

Who Is the Hayati 25K For?
The Hayati pro ultra plus 25k is best suited for:
- Heavy smokers switching to vaping. The 20mg nicotine salt delivery and MTL draw closely mimics the sensation of a cigarette. The large puff count means you are not constantly replacing devices.
- Ex-disposable bar users. If you have been getting through multiple 600-puff bars per week, the Hayati 25K delivers the same simplicity (no coil changes, no refilling messy liquid) at a fraction of the per-puff cost.
- Vapers who want variety without carrying two devices. The dual-flavour twist system lets you switch profiles in seconds.
- Anyone concerned about the UK single-use vape ban. As a rechargeable, refillable-pod device, the Hayati 25K is fully compliant and will remain so.
It is less suited to vapers who prefer sub-ohm direct-lung hits, those who want variable wattage control, or experienced vapers who want to mix their own liquids.

Our Verdict
The Hayati Pro Ultra Plus 25K earns its position as the leading high-puff prefilled kit in the UK. The dual-flavour twist system is genuinely useful, the LCD display adds real-world value, and the cost per puff is the lowest of any rechargeable device in its class. At £10.99 single or £9.00 each on the 2-for-£18 deal, it is hard to find a better value proposition for moderate-to-heavy vapers looking to move away from single-use bars.
The only meaningful drawbacks are the weight (heavier than a 600-puff bar) and the fact that it requires charging - neither of which is a real concern for daily use.

How many puffs does the Hayati Pro Ultra Plus 25K actually give?
The device is rated at 25,000 puffs across its two pods combined. Real-world puff counts depend on draw length and frequency. Short draws (1-2 seconds) will get closer to the rated figure; longer draws (3+ seconds) will reduce total puff count. Most users report getting between 20,000 and 25,000 puffs in practice.
Is the Hayati 25K legal in the UK after the vape ban?
Yes. The UK single-use disposable vape ban that came into force in June 2025 targets non-rechargeable, non-refillable devices. The Hayati Pro Ultra Plus 25K is rechargeable via USB-C and uses replaceable prefilled pods - it is fully compliant with the current UK regulations and can be sold and used without restriction. See our full collection of ban-compliant devices for alternatives.
Can you refill the Hayati 25K pods with your own liquid?
The Hayati 25K uses sealed prefilled pods that are not designed for manual refilling. The pods are replaced when empty rather than refilled. This keeps the experience simple and prevents leaks or coil flooding. Replacement pods are available in all the same flavours as the full kit - see our Hayati 25K replacement pods collection.
How does the Hayati 25K compare to the Lost Mary BM6000?
The Hayati 25K delivers 25,000 puffs at £0.044 per 100 puffs. The Lost Mary BM600 delivers 600 puffs at £0.63 per 100 puffs - over 14 times more expensive per puff. The Hayati also has an LCD display, dual-flavour system, and USB-C charging that the Lost Mary lacks. For a full breakdown, read our Lost Mary vs Hayati 25K comparison.
How long does the Hayati 25K battery last between charges?
The 850mAh battery typically lasts 1-3 days between charges depending on usage intensity. A moderate user taking 200-300 puffs per day will generally charge every 2 days. The USB-C fast charge takes under one hour from flat to full.
What nicotine strength does the Hayati 25K use?
All Hayati 25K pods contain 20mg nicotine salt - the maximum permitted under UK TPD regulations. Nicotine salt provides a smoother throat hit at higher nicotine concentrations compared to freebase nicotine, making it well suited to smokers switching to vaping. There is currently no 0mg nicotine option in the Hayati 25K range.
Where is the cheapest place to buy the Hayati 25K in the UK?
UK Vape World stocks the Hayati Pro Ultra Plus 25K at £10.99 single or 2 for £18 (£9.00 each). The 2-for-£18 deal is the best per-unit price available from any authorised UK retailer. Shop the Hayati 25K here.
What is the difference between the Hayati 25K and the Hayati Pro Max 15K?
The Hayati Pro Max S Plus 15K offers 15,000 puffs at £8.99, while the Pro Ultra Plus 25K offers 25,000 puffs at £10.99. The 25K also adds the dual-flavour twist system and the LCD display - neither of which is available on the 15K. For vapers who want the longest possible device life and the most features, the 25K is the better choice. The 15K kit suits those on a tighter budget or newer to pod vaping.
