Hayati Pro Max 4000 Review: Is the 4K Still Worth It?
The compact end of the Hayati range
Searches for the Hayati Pro Max 4000 keep climbing, and it is easy to see why: it packs up to 4000 puffs and a hefty 1400mAh pre-charged battery into a device that costs £10.99 and needs zero setup. For a lot of people it is the first Hayati they try before moving up the range.
This review covers what the 4K does well, its honest limits, and how it compares with its bigger siblings, the Pro Ultra 15000 and the Pro Ultra Plus 25000, so you can pick the right rung on the Hayati ladder first time.
Ratings
Compact, tidy and comfortable in hand, with the crystal-style look the range is known for.
The 1400mAh cell is generous for a 4000-puff device: the battery is never the thing that runs out first.
Bold, sweet-leaning Hayati flavours that stay consistent through the tank.
Pre-charged and prefilled: unbox, draw, done.

Pros & Cons
Pros
- Generous 1400mAh battery for a 4000-puff device.
- Bold Hayati flavour delivery from first draw to last.
- Zero setup: pre-charged and prefilled.
- Pocketable next to the big 15K and 25K kits.
Cons
- Sealed unit: no refills and no recharging accessories included.
- 4000 puffs is small by 2026 standards for the money.
- No display or level indicators.
- Cost per puff is far higher than the 15K and 25K kits.
Specifications
Who the Pro Max 4000 suits best
Occasional and social vapers first: if a device sits in a drawer between weekends, 4000 puffs and a big battery beat a 25K kit going stale. It is also the lowest-commitment way to test whether Hayati flavours suit you before buying up the range.
Daily vapers should do the maths though: the Pro Ultra 15000 costs £7.99 for nearly four times the puffs. If you vape every day, start there instead.

Expert Opinions
Jamie Ellis
•Senior Vape Tester — Vape Forest UK
Rates the 4K as the right buy for exactly one person: the light vaper who values freshness and pocket size over cost per puff. Everyone else should climb the range.
Pros
- Battery outlasts the liquid comfortably.
Cons
- Weak value for daily use.

•Vape Reviewer & Content Editor — Vape Forest UK
Points to the rising search interest as proof the 4K remains many people’s entry point to Hayati. His advice: pick your favourite flavour here, then buy it again on the 15000.
Pros
- Ideal flavour-testing format.
Cons
- No indicators of any kind.
Our Verdict
The Pro Max 4000 is a well-built, great-tasting pocket device that makes sense for light vapers and Hayati first-timers. For everyone else the sums point up the range: the Pro Ultra 15000 gives almost four times the capacity for three pounds less. Know which vaper you are and buy accordingly.
