In the embodiment of the present application, the detection pin 115 of the first interface 11 may detect whether the detection pin 415 of the first connector 41 is grounded to determine whether the first device 10 is a master device or a slave device. If the detection pin 115 of the first interface 11 detects that the detection pin 415 of the first connector 41 is grounded, the first device 10 determines that the first device is a master device, and controls the charging module 13 to output a power voltage to the power pin 111 of the first interface 11 to supply power to slave devices (such as the second device 20 and the third device 30 shown in fig. 1), so that the first device 10 can reversely charge the second device 20 and the third device 30. If the detection pin 115 of the first interface 11 detects that the detection pin 415 of the first connector 41 is not grounded, the first device 10 determines that the first device is a slave device, and the power pin 111 of the first interface 11 may receive a voltage input by an external device, and may receive the voltage input by the external device to charge the external device.
Optionally, the manner for the controller 12 to detect whether the second device 20 is a device to be charged is specifically as follows:
the controller 12 detects whether the current of the data pin of the first connector 41 is in a first preset current interval.
In the embodiment of the present application, the data pins of the first connector 41 may include a positive data pin 412 and a negative data pin 413. If the second device 20 is a device to be charged, the positive data pin 212 or the negative data pin 213 of the second interface 21 of the second device 20 is grounded through a first specific resistance. Generally, the larger the allowable charging current of the device to be charged, the smaller the first specific resistance. For example, the first predetermined current interval may be between 0.5mA and 5 mA.
Optionally, the manner for the controller 12 to detect the allowable charging current of the second device 20 is specifically as follows:
the controller 12 determines a first target charging current corresponding to the current of the data pin of the first connector 41 according to the correspondence between the data pin current and the allowable current.
In the embodiment of the present application, the corresponding relationship between the data pin current and the allowable current may be pre-established and stored in the memory of the controller 12. Referring to table 1, table 1 is a table of correspondence between pin currents and allowable currents disclosed in the embodiments of the present application.
TABLE 1
| Pin current (mA) | Allowable Current (mA) |
| 0.5-1 | 500 |
| 1-3 | 1000 |
| 3-5 | 2000 |
As shown in table 1, different pin current intervals correspond to different allowable currents. The allowed current is the maximum charging current allowed for the second device 20.
Optionally, the manner for the controller 12 to detect whether the third device 30 is a data transmission device specifically includes:
the controller 12 detects whether the current of the data pin of the first connector 41 is in a second preset current interval, where the first preset current interval and the first preset current interval do not intersect. If the third device 30 is a data transfer device, the positive data pin 312 or the negative data pin 313 of the third interface 31 of the third device 30 is in a floating state. The current of the data pin of the first connector 41 is very small, close to 0 mA.
The second preset circuit interval is smaller than the second preset current interval. For example, the second predetermined current interval may be between 0mA and 0.5 mA.
It should be noted that, when it is detected that the third device 30 is a data transmission device, the power pin 111 of the first interface 11 may supply power to the power pin 311 of the third interface 31. The supply current is small, for example, the supply current of the power pin 111 of the first interface 11 can supply 25mA to the power pin 311 of the third interface 31.

The boosting circuit 132 may boost the voltage (e.g., 4.35V) of the battery 131 to a voltage (e.g., 5V) of a charging standard, among others. The boost circuit 132 may also be referred to as a boost circuit.
Optionally, the controller 12 is further configured to decrease the charging current output by the charging module 13 to the second device 20 when the charge of the battery 131 is lower than a preset charge threshold.
In this embodiment, the first device 10 may adjust the charging current output by the charging module according to the electric quantity of its own battery. For example, the first device 10 may decrease the charging current output by the charging module 13 when the electric quantity of the battery of the first device is lower than the preset electric quantity threshold, so that the charging current output by the charging module 13 is smaller than the first target current. The preset charge threshold may be preset, for example, the preset charge threshold may be set to 40% of the total charge of the battery.
For example, if the maximum charging current allowed by the first device 10 is 1000mA when the first device 10 charges the second device 20, when the battery capacity of the first device 10 is detected to be lower than 40%, the charging current output by the charging module 13 of the first device 10 is reduced from 1000mA to 100mA to prevent the battery capacity of the first device 10 from being rapidly consumed.
Optionally, the controller 12 is further configured to decrease the charging current output by the charging module 13 to the second device 20 when the supply current of the battery 131 in the first device 10 exceeds a preset current threshold.
Optionally, as shown in fig. 3, the first device 10 further includes a display device 14, where the display device 14 is configured to receive a charging current adjustment instruction input by a user, the charging current adjustment instruction is used to adjust a current that the first device 10 charges the second device 20 within a third preset current interval, and an upper limit of the third preset current interval is the first target charging current.
In the embodiment of the present application, for example, if the maximum charging current operated by the second device 20 is 1000mA, a charging current adjustment progress bar may be displayed on the display device 14. As shown in fig. 3, the user may adjust the current of the first device 10 to the second device 20 from 1000mA to 700mA by sliding a finger on the charging current adjustment progress bar.
