The Drip'n EVO by Envi runs three power modes, and that's the part worth understanding before the 28,000 number. Eco stretches the battery and e-liquid the furthest, Boost pushes more vapour and flavour but uses it up quicker, and Normal sits in between. So 28,000 is really the Eco ceiling.

It's rechargeable, which it has to be at this size, since no built-in battery covers that many puffs on one charge. Nicotine is 20 mg/mL salt.

There are 19 flavours, a deep mix of fruit and iced blends like Grape Ice, Peach Blue Razz Ice, and Pineapple Coconut Ice. With this many puffs in one device, most people settle on a flavour or two and stay there a while. Real puff count depends on which mode you run and how you draw.
