An electronic cigarette vaporiser system including a vaporiser and a single piezo-electric pump that both withdraws liquid from a cartridge and also pumps controlled amounts of liquid into a reservoir in the vaporizer. The piezo-pump can be in a case that enables the vapouriser to be stored, and the cartridge is attached to or inserted into the case. The case both re-fills the vapouriser with liquid and re-charges a battery in the vapouriser.
