The Power Cube is a modular, universal, self-contained power unit consisting of an engine coupled to a hydraulic pump, providing power from hydraulic fluid at high pressure through quick connect hoses. It is designed to function as a modular and interchangeable power supply for GVCS and other open source technologies.
