The Flavour Beast Unleashed runs three settings: Standard, Boost, and Unleashed. Each one pushes the dual mesh coils harder, trading battery and e-liquid for more vapour and flavour. The 20,000 puff rating is what you'd get on the most efficient setting, so running it on Unleashed uses it up quicker. That's the trade-off.

It's rechargeable, which it needs to be to reach those numbers, and it runs 20 mg/mL salt.

There are five flavours, all on the sweeter fruit side: Epic Berry Swirl, Epic Grape, Epic Peach Mango, Epic Strawberry Watermelon, and Epic Watermelon Kiwi. A smaller list than some, but distinct enough. Real puff count depends on which mode you favour and how you draw.
