Introduction
The Hayati Pro Max 4000 Disposable Vape earned its reputation as one of the most popular big-puff devices in the UK, with advanced technology, a sleek design, and an impressive array of features. Formerly known as Crystal Pro Max, the device was rebranded to provide an even better vaping experience. In this review we look back at the key features and benefits that made the Hayati Pro Max 4000 a favourite with new and experienced vapers — and at the rechargeable successor that has taken its place.
Key Features of the Hayati Pro Max 4000 (Historical Overview)
The Hayati Pro Max 4000 Disposable Vape was designed to deliver a superior vaping experience through a combination of features that were ahead of their time:

3. Premium E-Liquid Quality

What Replaced the Hayati Pro Max 4000?
When the UK single-use vape ban took effect, Hayati's answer was the Hayati Pro Max Plus 6000 — a rechargeable device using swappable prefilled replacement pods. Everything people liked about the 4000 carries over: the same 20mg Hayati nic salt, draw activation, a huge flavour range (57+ flavours), and mesh-coil performance — now upgraded to a dual mesh coil, up to 6000 puffs per pod, and USB-C charging. Instead of throwing the whole device away, you keep it and swap the pod.

Benefits the Hayati Pro Max 4000 Was Known For
Enhanced Vaping Experience
The combination of Mesh Coil 1.1 technology, premium e-liquid, and a powerful battery meant each puff was rich, flavourful, and satisfying.
Convenience and Portability
Its compact, leak-proof build made it a favourite with vapers on the go, and draw activation kept it effortless to use.
Wide Range of Flavours
The Hayati Pro Max 4000 offered 61 unique flavours — from fruity and minty to sweet and tobacco profiles. That flavour breadth remains a Hayati hallmark today across the Pro Max Plus 6000 pod range.
Value for Money
With 4000+ puffs per device, it offered strong value in its day — though today's replaceable-pod format works out better still, since only the pod is replaced rather than the whole unit.
FAQs for Hayati Pro Max 4000 Owners
Can I still buy the Hayati Pro Max 4000 in the UK?
No. Since 1 June 2025, UK businesses can no longer sell or supply single-use (disposable) vapes, and the Pro Max 4000 is a single-use device.
Is it illegal to own or use one?
No — the law restricts businesses from selling or supplying single-use vapes. It does not prohibit personal possession or use of a device you already own.
What's the closest device to the Pro Max 4000 today?
The Hayati Pro Max Plus 6000 — same brand, same nicotine strength, bigger puff count per pod, and rechargeable with swappable pods.
Do the old 4000 flavours exist in the new range?
Most of the popular profiles (Blue Sour Raspberry, Watermelon Ice, Triple Mango and more) continue in the Pro Max Plus 6000 pod range.
Conclusion
The Hayati Pro Max 4000 Disposable Vape was more than just a vaping device — it helped define the big-puff era in the UK and built the reputation Hayati enjoys today. While the single-use format it used can no longer be sold, its strengths live on in the rechargeable Hayati Pro Max Plus 6000: the same flavours and satisfaction, with less waste and better long-term value.
