Hayati built its name on big-puff disposables, so a lot of vapers meet the Pro Ultra Plus 25000 expecting another sealed device with a bigger number on the box. It is not that. The Plus is a rechargeable prefilled pod kit: the battery body stays with you, and the e-liquid arrives as a sealed pack that you replace when it runs dry. That one change alters how you buy it, how you use it and which refills you can put in it, and the naming does not make any of this obvious. This guide covers the three questions we get asked most about the Hayati Pro Ultra Plus 25000 prefilled pod kit: how it works, which packs fit, and how to fit one.
Pro Ultra 15000 and Pro Ultra Plus 25000 are different devices
The confusion starts with the original Hayati Pro Ultra 15000. That was a disposable: two sealed 12ml tanks built into one body, a 550mAh battery that recharged over USB-C so you could finish the liquid, a small display with battery and puff count, and nothing to open. When both tanks were empty, the device was finished.
The Pro Ultra Plus 25000 keeps the twin-tank idea and drops the throwaway part. Its body holds an 850mAh battery, an animated display and a USB-C port, and the top section lifts out. Inside that section sits a 2ml pod with a dual mesh coil and two 10ml containers that feed it, one on each side. Those three parts are what you replace, together, as one pack. The body is kept and recharged.
Because the 15000 has no removable pod, there is nothing to interchange: no pack fits it, and its tanks cannot be moved into the Plus. Hayati’s other rechargeable kit, the Pro Max Plus 6000, has a removable pod too, but it is built around a single 10ml container on a different frame, so its packs do not fit the Plus either and the Plus packs do not fit it. The only refill that fits the Pro Ultra Plus 25000 is the pack sold for it, sometimes labelled 25K rather than 25000. Both labels mean the same device.
How the Plus works day to day
There is no button. You draw, it fires, and the airflow is fixed, so there is nothing to set or get wrong. The two containers are independent: a 180 degree twist of the mouthpiece switches the draw from one to the other, and the display shows the battery level and how much liquid is left on each side. Many packs are paired, with a different flavor in each container, so the twist is also how you change taste mid-day without carrying a second device. Single-flavor packs fill both containers with the same liquid, and the e-liquid is nicotine salt at 20mg/ml throughout.
The kit is larger than a pocket disposable, at roughly 10.7 by 5.3 by 2.9 centimeters in a metal shell, and the battery is sized to be charged rather than to last the whole pack on one fill. Expect to plug it in every day or two with normal use. Charging does not touch the liquid, and running the battery flat does not waste any; it simply pauses the device until it is topped up.
Swapping in a new pack: five steps
- Check the pack name before you open it. It must say Pro Ultra Plus 25000 or 25K. A Pro Max Plus pack looks similar at a glance and will not seat.
- Hold the body and pull the mouthpiece section straight up. The used pod and both containers come out with it as one unit; set it aside.
- Open the new pack. The pod and each container have a silicone plug and a sticker sealing their openings. Remove every one of them, or the liquid cannot flow.
- Clip the fresh pod into the mouthpiece section, then push the two containers onto the sides of the pod frame. The parts are color coded, so if something resists, you have the wrong side rather than a tight fit.
- Lower the assembled section back into the body and press down until it sits flush. Leave it two or three minutes before the first draw so the coil can soak; a dry first puff is the usual way a brand new coil gets burned.
The whole job takes a few minutes and needs no tools, no bottle and no cleaning. A fresh pack of Hayati Pro Ultra Plus 25000 replacement pods contains the 2ml pod with its coil, both 10ml containers and a leaflet, and nothing else, so there is no battery to pay for twice.
Reading the 25,000 figure
The puff rating is a manufacturer figure from short, machine-timed puffs, and it is best read as a ceiling. A working rule that holds up well in practice: a former pack-a-day smoker takes around 600 puffs a day, which puts a full pack at roughly six weeks. Someone at ten a day lands nearer three months. Long, slow draws use more liquid per puff and bring both figures down. What the rating does promise is that the coil arrives new with every pack, so the flavor at the end of a pack is the same as at the start, which is the main thing that separates this format from refilling one pod over and over.
Who it suits, and who should skip it
The Pro Ultra Plus 25000 suits adult vapers who liked the simplicity of disposables and want to keep that routine while keeping the device. There is nothing to fill, no coil to choose and no setting to adjust, and a flavor change is a pack change. It also suits anyone who likes carrying two flavors and switching between them.
Skip it if you want control over your liquid. The packs come in one strength, 20mg/ml, and only in Hayati’s own flavors; if you want a lower strength, a particular brand of liquid or a cheaper cost per milliliter, a refillable pod kit will serve you better. And if you still have an original Pro Ultra 15000 in a drawer, treat it as what it is, a disposable with a charging port, rather than something you can revive with a pack made for the Plus.
