How Long Does Each Actually Last?
Puff-count claims are theoretical maximums. Here's what we see in real-world use at Isle of Vapes.
Hayati Pro Max+ 6K
- Heavy user (~500 puffs/day): ~1.5 days per kit
- Medium user (~300 puffs/day): ~2.5 days per kit

Pro Max+ 6K — The Pocket Companion
The Hayati Pro Max+ 6K is the everyday workhorse. Pen-style, light enough for a shirt pocket, no display to distract you. It uses Hayati's signature mesh coil for crisp flavour delivery and runs the classic 20mg nic-salt formulation.
We stock it in football-themed editions (England, Scotland, Wales) and the standard range. Flavours include Blue Razz GB, Fresh Mint, Lemon & Lime, Blueberry Raspberry, Juicy Peach and more.
Best for
- Light to moderate vapers (under 300 puffs/day)
- People who want something pocket-friendly
- Anyone switching from a 600-puff disposable
- Budget-conscious buyers
Pro Ultra+ 25K — The Long-Distance Runner
The Hayati Pro Ultra+ 25K is the 2026 "big puff" benchmark. The standout feature is the dual-tank system: load two different flavours and twist the mouthpiece to switch between them. The built-in smart display shows real-time battery percentage and e-liquid levels, so you never get caught short.
Internally, it uses the legal 2ml + 10ml format (see our big puff vape safety guide for how this works under UK TPD rules).
Best for
- Heavy daily vapers (300+ puffs/day)
- Anyone who likes alternating between two flavours
- Travellers and festival-goers who want a single device to last a week
- People moving from multiple disposables per day
Cost Per Puff — The Real Comparison
| Kit | Price | Puff count | Cost per 1,000 puffs |
|---|---|---|---|
| Pro Max+ 6K | £8.99 | 6,000 | ~£1.50 |
| Pro Ultra+ 25K | £10.99 | 25,000 | ~£0.44 |
The Pro Ultra+ 25K delivers roughly 3.4× the puffs per pound spent. For heavy vapers, the maths is overwhelming.
Flavours Available
Both kits share most flavour names — Blue Razz GB, Blueberry Raspberry, Blue Sour Raspberry, Fresh Mint and Lemon & Lime. The Pro Ultra+ 25K adds a wider drinks-and-sweets selection including Mr Blue (in the Manchester edition). See our full UK flavours guide for what's trending.

How to Make Either Kit Last Longer
- Charge to ~80% rather than 100% when you can — better for the battery long-term.
- Avoid chain vaping — leave 5–10 seconds between draws.
- Store at room temperature; heat shortens battery life.

Frequently Asked Questions
Are Hayati Pro Max+ 6K and Pro Ultra+ 25K legal in the UK?
Yes. Both are rechargeable, use replaceable pods/cartridges and are fully TPD-compliant under the post-ban rules (see our disposable vape ban explainer).
Which has better flavour?
Both use Hayati's mesh-coil tuning. The 25K has a slight edge thanks to the bigger pod, but the difference is small.
Can I refill the pods myself?
No — both are pre-filled, sealed pods. If you want a refillable kit, see our best refillable pod kits guide.
How will the October 2026 vape tax affect these?
The duty is volume-based: £2.20 per 10ml. The 6K (2ml) adds about 44p in duty; the 25K (12ml total) adds about £2.64. Full numbers in our UK vape tax 2026 guide.
The Verdict
If you vape less than 300 puffs a day or you want the most pocket-friendly kit, buy the Pro Max+ 6K. If you vape more, want dual flavours or just want the lowest cost per puff, buy the Pro Ultra+ 25K. For most ex-disposable users moving from a 600-puff bar to something bigger, the 6K is the natural step. Heavy users should skip straight to the 25K.
