When you look at a high-puff vape, it is easy to focus on the number in the name. With the Hayati Pro Ultra Plus 25K vape kit, though, the amount of e-liquid it holds matters just as much as the headline puff count.
That capacity is split between small pods and larger tanks and the same layout applies to every pack of Hayati Pro Ultra Plus 25K refills. Here is how it all adds up.
How Is the 24ml Capacity Split?
According to the current Vape 360 listing, each kit contains two 2ml prefilled pods and two 10ml sealed auto-refill tanks, giving 24ml in total.
| Component | Quantity | What it does |
| 2ml prefilled pod | 2 | Active vaping chamber, each with its own 1.1 ohm mesh coil. |
| 10ml auto-refill tank | 2 | Sealed reserve that feeds its connected pod. |
| Total e-liquid | 24ml | Combined capacity of the pods and tanks. |
| E-liquid type | 20mg (2%) | Nic salt, 50/50 VG/PG, mouth-to-lung draw. |
It is worth being clear about one thing: the 24ml figure is the combined capacity of the pods and tanks, not 24ml sitting inside the pods at once.
What Do the 2ml Pods Actually Do?
Each pod is connected to its own 10ml tank and the device holds both at the same time, with a separate flavour on each side. As you vape, the pod is topped up from its tank using a simple gravity feed. There is no manual filling and no priming.
That makes the 2ml pod the active chamber, while the 10ml tank acts as the larger reserve. The pods are not designed to be filled by hand.
Why Does the 10ml Tank Matter?
The tanks are what give the system its generous overall capacity. Instead of replacing a tiny pod every time it runs low, the connected tank keeps feeding it until both are empty. Then you replace the whole pod-and-tank unit with a fresh pack.
This structure is also how the product sits within UK rules. Vape 360 lists it as TPD compliant and MHRA registered, with each 2ml pod staying within the legal size limit while the 10ml tanks sit as separate sealed containers.
Does 24ml Mean 25,000 Guaranteed Puffs?
Not exactly. The listing describes the kit as giving up to 25,000 puffs per pack, with the real figure depending on draw length. A puff is not a fixed amount of e-liquid, because shorter draws use less and longer ones use more.
So the 25,000 figure is best read as a stated maximum. Light users can stretch a pack close to a month, while heavy, all-day vapers tend to get through one in around two weeks.
How Do the Two Flavours Fit In?
The capacity is divided across two sides, so the device can carry two flavours at once. Vape 360 lists 45 in all, made up of 23 singles and 22 duos. Singles put the same flavour in both pods, while duos put a different one in each.
Kiwi Banana / Strawberry Banana is a popular duo and Mr Blue and Lemon and Lime both come as singles. To change sides, pull up and rotate the mouthpiece and the display shows whether you are on L or R.
How Do You Swap a Finished Pack?
When both tanks are empty, the flavour may start to thin out and the transparent tanks make it easy to check the e-liquid level. To replace them, firmly pull out the old unit, open the new pack and remove the stickers and silicone bungs. Attach each pod to its matching colour-coded tank, push the assembled pack into the device until it clicks, then wait a minute or two for the coils to saturate before taking your first draw.
What Does It Cost?
At the time of writing, the kit is £11.99 or 3 for £30 and refill packs are £7.95 each or 2 for £15. Light users needing one pack a month would spend £7.95, while heavier users getting through two could use the 2 for £15 deal. Because the 850mAh battery carries over, you only pay for pods once you own the device. Prices can change, so check the current listing.
Who Is It For?
It contains nicotine and is intended for adult smokers looking to switch, not for under-18s, non-smokers, pregnant or breastfeeding people or anyone with heart or seizure conditions. Vaping is not risk-free.
Final Thoughts
Understanding the 2ml plus 10ml structure explains far more about this product than the 25K name alone. Two small pods act as the vaping chambers, two 10ml tanks provide the reserve and the up-to-25,000-puff claim depends on how you draw. Read together, the figures give a much clearer picture of what you are buying.
