Disposables are how most UK smokers first try vaping: no buttons, no refilling, just draw and go. They are also where the most confusion lives. Advertised puff counts are measured by machines taking tiny one-second puffs, so a "600 puff" bar rarely delivers 600 puffs in real use, and the "how many cigarettes is this?" question has a more useful answer than the marketing suggests.
One big thing changed recently: the UK banned the sale of single-use vapes on 1 June 2025. The classic throwaway Elf Bar 600 and its rivals are gone from shelves, replaced by rechargeable, refillable versions of the same devices — usually with the same flavours and the same 2ml, 20mg/ml nic salt pods. The guides below have been updated for the ban, and the underlying numbers (puffs, nicotine, cigarette equivalents) still apply to the new versions.
Setup, the twist-to-switch pod system, and the question everyone asks: no, the IVG 2400 doesn't charge — here's why, and what to do when it dies early.
