A portable dispenser is adapted to filling water balloons and water pistols. A reservoir is pressurized by a hand pump that draws air in from the atmosphere and forces the air into the reservoir. The pressure in the reservoir forces water down a flexible tube to a trigger mechanism in a water pistol. The trigger mechanism performs three functions: it throttles the water, it acts as relief valve by releasing water if the pressure is greater than a predetermined limit, and it indicates the pressure within the reservoir. When the trigger mechanism is actuated, water flows through the mechanism to a valve that directs the water either to a filling nozzle or to a spraying nozzle. In an alternative embodiment, the pump takes water from a storage chamber within the reservoir and pumps it into a high pressure chamber within the reservoir.
