It is also understood that the first output port circuit 15 may be a port that does not include a connecting wire, and may be set according to actual requirements. Furthermore, the main control circuit 12 of the present invention is configured to detect whether the operating state of the first output port circuit 15 is the charging mode or the mobile power mode, wherein the first output port circuit 15 is used as the power output port in the charging mode, and is used for transmitting power to the external device; the first output port circuit 15 is used as a power input and power output port in the mobile power mode for charging an external device and transmitting power to the mobile power. The present embodiment determines the operation state by detecting whether an external load or an external power source is connected to the first output port circuit 15 and whether the input circuit 10 receives an external alternating voltage. Specifically, when the input circuit 10 receives an external ac voltage and the first output port circuit 15 is connected to an external load, the operating state is determined to be the charging mode; when the input circuit 10 does not receive the external ac voltage and the first output port circuit 15 is connected to the external load or the external dc power supply, it is determined that the operation state is the portable power mode.

It can be understood that, the main control circuit 12 detects the working state of the first output port circuit 15 and obtains a working signal, and the main control circuit 12 controls the on/off of the first switch circuit 13 and the second switch circuit 14 according to the working signal to switch different working paths of the mobile power supply circuit 1, so as to switch the working mode of the first output port circuit 15, so that the first output port circuit 15 can be used as both an electric energy input port and an electric energy output port. When the portable power source charging device is used, a user can directly charge the portable power source through the first output port circuit 15, the portable power source is not required to be charged through an additional charging wire, and the problem that the first output port circuit 15 of the portable power source in the prior art is single in functionality is solved. That is the utility model discloses a portable power source circuit 1's first output port circuit 15 can carry out electric energy output and can also carry out electric energy input to portable power source.

More specifically, when the main control circuit 12 detects that the operating state of the first output port circuit 15 is the charging mode, at this time, the main control circuit 12 controls the first switch circuit 13 to be turned on and the second switch circuit 14 to be turned off, the output end of the input circuit 10 passes through the first switch circuit 13 and then is output through the first output port circuit 15, and at this time, the first output port circuit 15 only serves as an electric energy output port to realize the electric energy output mode. When the main control circuit 12 detects that the working state of the first output port circuit 15 is the mobile power supply mode, at this time, the main control circuit 12 controls the second switch circuit 14 to be switched on and the first switch circuit 13 to be switched off, the output end of the input circuit 10 is connected with the first output port circuit 15 after passing through the power management circuit 11 and the second switch circuit 14 in sequence, at this time, the first output port circuit 15 can realize the electric energy output mode or the electric energy input mode, namely, at this time, the first output port circuit 15 is used as an electric energy input port to realize the electric energy input mode when being connected with an external direct-current power supply; or when the first output port circuit 15 is connected to an external power load, the power output mode is realized as a power output port.
Further, referring to fig. 2, the input circuit 10 at least includes an AC-DC converting circuit 102, and the AC-DC converting circuit 102 is connected to the first output port circuit 15 through the first switch circuit 13.
More specifically, the input circuit 10 further includes an AC input circuit 101, and the AC input circuit 101 is connected to the first output port circuit 15 through an AC-DC conversion circuit 102 and a first switch circuit 13 in this order.
It can be understood that, with this design, it is possible to enable the first output port circuit 15 of the mobile power supply circuit 1 to realize the unidirectional power output mode through the AC-DC conversion circuit 102 when the master circuit 12 controls the first switch circuit 13 to be turned on and the second switch circuit 14 to be turned off.

That is, if the first output port circuit 15 is connected to an external dc power source, the power input mode is implemented as a power input port, and if the first output port circuit 15 is connected to an external power load, the power output mode is implemented as a power output port.
Specifically, the main control circuit 12 switches the working path of the first output port circuit 15 according to the working signal, and when the first switch circuit 13 is turned on and the second switch circuit 14 is turned off, the working path of the first output port circuit 15 is: after the AC input circuit 101 passes through the AC-DC conversion circuit 102, the output end of the AC-DC conversion circuit 102 passes through the first switch circuit 13 and then is output through the first output port circuit 15; when the first switch circuit 13 is turned off and the second switch circuit 14 is turned on, the working path of the first output port circuit 15 is: the output terminal of the AC-DC conversion circuit 102 is input or output through the first output port circuit 15 after passing through the charge management circuit 111, the battery circuit 112, the voltage conversion circuit 113, and the second switch circuit 14 in this order.
Further, referring to fig. 2, the charging management circuit 111 is further connected to the main control circuit 12, and the main control circuit 12 can control the charging management circuit 111 to be turned on or off through the design.

When the mobile power supply circuit 1 is in the mobile power supply mode, the main control circuit 12 controls the charging management circuit 111 to be turned off, so that the output end of the AC-DC conversion circuit 102 stops charging the battery circuit 112 through the power management circuit 11.
Further, the first switch circuit 13 and the second switch circuit 14 of the first embodiment of the present invention each include a relay or a MOS transistor.
