Count on 5,000 to 7,000 realistic draws: ten days to two weeks for an average user, around a week for a heavy one. Devices with swappable pods reset the clock with each fresh pod while the battery keeps going for months.
As a rough guide, vapers draw ten to fifteen puffs where a cigarette gave ten, so a 10K device stands in for somewhere near 400 to 500 cigarettes’ worth of hand-to-mouth habit. The £6.99 to £11 price against that maths is why smokers who switch rarely go back.
If this is a one-off or occasional buy, the all-in-one is simplest. If a 10K device is your daily driver, pick the Pyne Pod Click or Elf Bar Dual and reorder pods; you will spend less within a month and bin far less plastic.
