It might be hard to believe, for those who were not vaping at the time, but 600 puffs once felt like a huge number. The amount has been shooting up in recent years, though. Two thousand. Five thousand. Ten. At one point, some clever chap or chapette clearly decided that wasn't enough, and here we are in 2026, where the Hayati Pro Ultra Plus 25K offers 25,000 puffs.
The interesting part is how they did it, though. Rather than one enormous sealed unit, each pack gives you a 2ml prefilled pod plus two 10ml auto-refill containers that feed it - and that's how you get to 25,000 puffs without carrying something the size of a nineties mobile phone.
