Table 1-1 shows the USB Type-C PD bidirectional charger specification; the USB Type-C port can be either a source or sink depending on the equipment plug in. The battery side supports 4- to 10-cells, the maximum charge current is limited to 3A. While in reverse mode, the output voltage is configured to 5V, 9V, 15V at 3A and 20V at 5A. The maximum output power is limited to 100W.
