Hayati Pro Ultra+ S Review: Does it Offer 50,000 Puffs?

The Hayati Pro Ultra+ S takes a different approach to high-puff prefilled kits: instead of making the device complicated, it combines a rechargeable battery with a two-flavour system that you control from the mouthpiece. The main question for this review is whether that setup is actually useful in everyday use, rather than whether the headline 50,000-puff number sounds impressive.

At first glance, the Pro Ultra+ S is fairly straightforward. It is an MTL device with draw activation, so there are no normal-use buttons or power settings to work through. The twist mouthpiece is the feature you'll notice most because it lets you move between the two flavours without carrying a second device.

The system uses an 850mAh rechargeable battery with USB-C charging. For the full technical breakdown — including the 1 × 2ml pod, 2 × 10ml auto-refill tanks and 22ml total e-liquid — see our Hayati Pro Ultra+ S 50K technical guide.

What is it like to use?

The strongest part of the design is simplicity. Inhale to activate the device and turn the mouthpiece when you want the other flavour. If you regularly alternate between two flavours, that is more convenient than changing devices or manually refilling a tank.

The device is designed for mouth-to-lung vaping and uses a 1.2Ω dual mesh coil. Rather than making claims about “50% better flavour” or guaranteed performance, the useful point is that the coil and pod system are built into the prefilled setup, so there is no separate coil installation for the customer to manage.

What does the 50,000-puff claim mean?

Hayati rates the complete system for up to 50,000 puffs. Treat that as a manufacturer maximum rather than a guaranteed personal result. Draw length and individual use affect the number of puffs you actually get.

Two flavours in one system

The Pro Ultra+ S supports two flavours, with the twist mouthpiece used to switch between them. That is probably the most practical reason to consider this particular Hayati model if you don't want to stay with one flavour throughout use.

Flavour preference itself is personal, so this review doesn't rank one option as objectively better than another.

What we like

• Simple draw-activated MTL operation
• Two-flavour switching through the twist mouthpiece
• 850mAh rechargeable battery
• USB-C charging
• Prefilled auto-refill system with no manual bottle filling during normal use

Things to consider

• The up-to-50,000 puff figure is a manufacturer rating, not a guaranteed result for every user.
• It is designed around a 20mg/ml prefilled system, so it does not offer the nicotine-strength flexibility of a refillable kit.
• The MTL format will not suit someone specifically looking for a direct-to-lung setup.

Our review summary

The Pro Ultra+ S makes the most sense for someone who wants a prefilled MTL device but values having two flavours available in the same system. Its twist mouthpiece is more meaningful in everyday use than the headline puff number because it changes how you actually interact with the device.
