The invention relates to portable liquid dispensers for transporting large quantities of liquid to a predetermined location and for dispensing the drinking liquid on demand. The liquid dispensing unit provides for the use of a hand truck which supports and carries an insulated hollow container suitable for retaining the drinking liquid. A rechargeable battery is positioned in a housing, the latter being detachably secured to the frame of the hand truck. A pump, electrically connected to the rechargeable battery, has a pressure switch which is activated when a drop of pressure in the fluid line is detected. The intake side of the pump is connected by a flexible hose to the interior of the container and the discharge side of the pump is connected to a manifold carried by the frame of the hand truck. A plurality of liquid dispensing hoses are connected to the manifold, each dispensing hose being provided with a handle control which opens, closes and controls flow rate and the fluid communication between the container and the dispensing hose. The pressure switch is activated by moving the handle control into the open position, which in turn activates the pump to supply drinking liquid upon demand.
