A power assisted drinking vessel, using a battery powered liquid pump provides pressurized, low volume liquid from the drinking vessel to a user's mouth through a straw, without the user having to draw or provide suction on the straw. The liquid pump is activated by pressing a momentary on-off electrical power switch. The power assisted drinking cup is capable of pumping many commonly ingested liquids such as water, soft drinks, alcoholic drinks, dietary/meal supplements or juices of various viscosity and at various flow rates and pressures. The powered drinking cup will be a benefit to patients in hospital or after dental work has been performed and will have appeal for many novelty use and sporting applications.
