Hayati Pro Ultra+ S: Battery, Puff, Dual Tank Explained

The Hayati Pro Ultra+ S is a rechargeable prefilled MTL system rated for up to 50,000 puffs. Its e-liquid setup is easy to misunderstand, so here is the important part: the system uses 1 × 2ml pod with 2 × 10ml auto-refill tanks, giving 22ml of e-liquid in total. The two-flavour setup is controlled through the twist mouthpiece.

The Pro Ultra+ S combines an 850mAh rechargeable battery with USB-C charging, draw activation and a 1.2Ω dual mesh coil.

Puff rating: up to 50,000

The manufacturer rates the complete system for up to 50,000 puffs. This is a maximum rating rather than a guaranteed number; actual puff count varies with individual use.

E-liquid system: 22ml total

The system consists of 1 × 2ml pod and 2 × 10ml auto-refill tanks. Together, these provide 22ml of e-liquid. The 10ml tanks automatically replenish the 2ml pod during use, so they should not be described as two separate 12ml tanks or as two 2ml pods.

Nicotine: 20mg/ml

The e-liquid uses a nicotine concentration of 20mg/ml. This describes the amount of nicotine per millilitre of e-liquid, not the total nicotine quantity in the whole system.

Battery: 850mAh

The built-in 850mAh battery is rechargeable through USB-C. How often it needs charging depends on individual use, so there is no fixed one-, two- or three-day battery-life claim.

Coil: 1.2Ω dual mesh

The system uses a 1.2Ω dual mesh coil and is designed for mouth-to-lung (MTL) vaping.

The Pro Ultra+ S is draw activated, so there is no button to press for normal vaping. Once the pod and auto-refill tanks are correctly fitted according to the supplied instructions, inhale through the mouthpiece to activate the device.

How does flavour switching work?

The system supports two flavours. Turn the mouthpiece to switch between them. This is part of the device's two-flavour setup rather than a reason to remove and replace the pod every time you want to change flavour.

What comes with the system?

• 1 × 2ml pod
• 2 × 10ml auto-refill tanks

The replacement pod/tank pack uses the same format: 1 × 2ml pod + 2 × 10ml auto-refill tanks.
