Basics
E-cigarette
An e-cigarette uses an electrically powered atomizer to heat e-liquid without burning tobacco. It typically consists of a battery, controls, liquid reservoir, coil and mouthpiece.
Open termDevice types
Disposable vape
A disposable vape is a prefilled complete device whose battery and liquid reservoir are generally not designed for user replacement. The whole device is electronic waste and requires separate collection.
Open termDevice types
Pod system
A pod system is a compact e-cigarette with a replaceable liquid module. Pods may be prefilled or refillable, while the battery and electronics of the base device are reused.
Open termParts & technology
Coil
The coil is the atomizer's heating element. It converts electrical energy into heat so liquid can aerosolise at the wick; resistance, material and power range must match the device.
Open termLiquids & ingredients
E-liquid
E-liquid is the fluid heated in an e-cigarette. Common ingredients include propylene glycol, glycerine, flavourings and optional nicotine; the specific product label is always decisive.
Open termLiquids & ingredients
Nicotine salt
Nicotine salt is a liquid form in which nicotine is chemically combined with an acid. It is often used in lower-power pod systems; the concentration stated in mg/ml remains essential.
Open termLiquids & ingredients
Propylene glycol (PG)
Propylene glycol, or PG, is a relatively thin carrier used in many e-liquids. It carries flavours effectively and affects the mixture's viscosity and draw sensation.

Comparisons
Disposable vape, pod system or e-cigarette?
These terms describe different device concepts. The key distinction is which parts can be refilled, recharged or replaced.

PG/VG ratio: which liquid fits technically?
PG and VG are the main carriers in many liquids. Their ratio affects viscosity, flavour delivery and aerosol volume.

Charge and store vape batteries safely
Lithium batteries store substantial energy in a small space. Damage, unsuitable charging or a short circuit can cause intense heat and fire.
Read guideSafety
E-liquid swallowed or in the eyes?
Nicotine-containing liquid can cause severe poisoning. Call 112 immediately for breathing difficulty, unconsciousness or other life-threatening symptoms.
Read guideDisposal
Dispose of disposable vapes correctly
An empty vape remains an electronic device with a battery. It belongs neither in household waste nor in packaging recycling.
