A rechargeable water dispenser pump is a motorized device that attaches to large water bottles or jugs (like 5-gallon, 19-L / 20-L), replacing manual lifting or pouring. You place the pump’s inlet tube into the water jug, secure the pump head on top, and then at the push of a button (or automatically, in some models) it pumps water out through a spout.

• It has a small built-in electric motor + pump mechanism.

• Powered by a rechargeable battery (often Li-ion or similar). USB charging is common.

• The pump draws water up through a hose into a spout, controlled via a simple switch.
