If you're a smoker thinking about switching, a vape can look complicated. It really isn't. Once you know the four parts and what each one does, the whole thing makes sense — and you'll buy your first kit with a lot more confidence.
Strip away the branding and every vape is the same handful of bits:
Battery — powers the device. On a pod kit it's built in and you charge it by USB.
Coil — a small heating element wrapped in cotton wick. This is the part that does the work.
E-liquid — the flavoured liquid (with or without nicotine) that soaks into the wick.
Tank or pod — holds the e-liquid and houses the coil.
Here's the whole process in one breath:
You inhale (or press the button on some kits).
The battery sends power to the coil.
The coil heats the e-liquid soaked into its wick.
The liquid turns to vapour — not smoke — and you breathe it in.
There's no burning and no combustion. That's the key difference from a cigarette, and it's why the NHS supports vaping as a way to stop smoking.
The nicotine is in the e-liquid, not the device. You choose the strength that matches how much you used to smoke, and the type — nic salt or freebase. Most people switching from cigarettes do best on a higher-strength nic salt in a small kit, because it satisfies a craving quickly.
The coil wears out — it's the only consumable part apart from e-liquid. When flavour fades or you get a burnt taste, it's time for a fresh one. Knowing how often to replace your coil and how to change it is the one bit of maintenance worth learning early.
For almost everyone switching from smoking, that's a simple pod kit: built-in battery, easy pods, tight cigarette-like draw. No wattage settings, no fuss. Once you've settled in you can explore bigger devices — but you don't need to understand sub-ohm clouds to quit smoking.
That's the whole thing: battery heats coil, coil turns liquid to vapour, you breathe it in. Simple.
