2 Flavors in 1
Two sealed flavour tanks in one body with a selector between them is the rule this page collects by, and what sits behind those tanks varies widely – from size class to whether a single battery serves both – so the arrangement is worth reading before the flavour pair.

What counts as two flavours in one device
Two tanks, one mouthpiece. Every device here separates its liquid into two independent tanks that a switch or a slide selects, so nothing mixes between them. The catalog carries two models, both listed in the table below.
| Model | Advertised puffs | Liquid | Coil | Battery |
|---|---|---|---|---|
| FiHP 40K 2in1 | 40,000 | 36 ml | Dual mesh, 0.9 Ω | 850 mAh |
| FiHP 36K 2in1 | 36,000 | 32 ml | Dual mesh, 1.0 Ω | 850 mAh |
Both figures are manufacturer claims, measured under the maker’s own test conditions. The two tanks are filled at the factory and share one battery.
Separate tanks rather than a mixed middle
The comparison that matters when choosing a format is where the flavour changes. The three-tank design under 3 in 1 adds a third position, and the 200K model listed under 8 in 1 mixes some of its positions by design — the attribute on that product says four independent flavours plus four mixed ones. If you want each tank to taste exactly as it was filled, the two-tank layout is the simpler of the two.
One tank, no switching at all, sits in the single flavour category.
What switching costs you in hardware
A second tank means a second coil chamber and a wider body, and both models here carry 850 mAh — more than the single-tank devices. That capacity is reported in the data sheet rather than measured here, and rechargeability is not claimed on this page: the charging port is listed on each product page.
An empty tank does not end the device. Both models report a liquid figure in their attributes, and both appear under e-liquid level display, where the same reading is collected across the catalog.
Where these two sit in the range
In draw style both are restrictive, the profile described on mouth-to-lung. In puff tiers the two sit two steps apart: 36,000 against 40,000. The step below them is the 30,000-puff page, and above them the 60,000-puff one, which is where a three-tank device sits.
Availability differs per model and is shown on the product pages. The shop overview lists what is currently on the catalog, and the brand page covers the full FiHP range.
Can one tank run dry while the other is full?
The two tanks are physically separate, so they drain at their own rate. The data sheet gives the liquid figure for the whole device rather than per tank, which is why the display reading is the practical guide.
