As the title says, thread about the different types of e-liquid containers that are attached to batteries.
Cartomisers are the sealed disposable containers used in cigalike devices. They are prefilled with the liquid and have a built in atomiser to vaporise the liquid
Clearos, clearomisers and tanks are different names for the same thing, a refillable container for the liquid which also has an atomiser - though in many cases this atomiser can be replaced or even "rebuilt" i.e. the coil and wick replaced.
