Abstract

A cordless liquid dispensing apparatus (100) for hand held use comprises a mount (116) for a reservoir of liquid (112), an electrically driven pump (106) arranged to deliver liquid from the reservoir (112) to a discharge tip (120) at a liquid delivery rate, and a high voltage power source (104) arranged to charge the liquid at the discharge tip (120). A microcontroller is arranged to control the pump speed (106), so as to adjust a non-zero value of the liquid delivery rate.
