A multi-input power manager includes: first to n-th maximum power point tracking circuits for respectively receiving first to n-th powers from the outside and controlling voltages of first to n-th nodes to be first to n-th reference voltages based on the first to n-th powers; first to n-th input capacitors which respectively store the first to n-th powers by control of the first to n-th maximum power point tracking circuits, and are respectively connected to the first to n-th nodes; first to n-th transfer switches which are respectively connected to the first to n-th nodes, and output powers respectively stored in the first to n-th input capacitors, responding to first to n-th transfer switching signals; and a transfer switch control circuit which compare the first to n-th reference voltages and the voltages of the first to n-th nodes respectively, and generate the first to n-th transfer switching signals accordingly.
