Based on the embodiment, each Type-C interface module comprises a Type-C interface, each Type-A interface module comprises a plurality of parallel Type-A interfaces, and each Type-C interface and each Type-A interface are respectively used for accessing a single load; correspondingly, according to the number of loads and the voltage and power required by the loads, the AC/DC power supply module outputs the voltage required by the loads through the voltage regulating module, and distributes the required power to the loads, which specifically comprises: if any one Type-C interface module is connected with a single second load, the AC/DC power supply module outputs the voltage required by the single second load through the Type-C voltage regulating module corresponding to any one Type-C interface module, and distributes the required power for the single second load; if any one Type-A interface module is connected with a single first load, the AC/DC power supply module outputs the voltage required by the single first load through the Type-A voltage regulating module corresponding to any one Type-A interface module, and distributes the required power for the single first load; if any one Type-A interface module is connected with a plurality of first loads, the AC/DC power supply module outputs the lowest voltage required by the plurality of first loads through the Type-A voltage regulating module corresponding to any one Type-A interface module, and the required power is distributed for the plurality of first loads respectively.
Specifically, to the Type-C interface part, if each Type-C interface module only comprises one Type-C interface, namely any one Type-C interface module is connected into a single first load, the AC/DC module is controlled to output the maximum voltage and the maximum power which can be met by the single first load through the Type-C voltage regulating module corresponding to each Type-C interface module, so that the single first load is enabled to realize quick charging.

Further, the Type-a interface part of the apparatus further includes: if the plurality of first loads include small micro devices, the small micro devices are defined as micro electronic products with a charging voltage of not more than 5V and a charging current of not more than 1A. Because the small micro-device has smaller resistance and smaller power; according to the existing power supply voltage division scheme, the charging efficiency can be prolonged, in order to guarantee the practicability and convenience of the small micro-device, the AC/DC power supply module outputs the voltage required by the small micro-device through the Type-A voltage regulation module corresponding to any one Type-A interface module, and the required power is distributed for the low-voltage and low-current low-power device.
For example, if the first loads include a low-voltage low-current low-power device such as a bluetooth headset, in order to prevent the bluetooth headset from being preempted by other fast-charging devices of the Type-a interface, the AC/DC power supply module outputs a voltage of 5V (charging voltage of the bluetooth headset) through the Type-a voltage regulation module corresponding to the bluetooth headset, and distributes the voltage to the bluetooth headset, that is, the maximum current required by the bluetooth headset, that is, the maximum power required by the bluetooth headset; simultaneously, the load that other Type-A interfaces of the Type-A interface module that inserts for bluetooth headset inserts accessed distributes suitable power.
Based on the above embodiment, as shown in fig. 2, the apparatus further includes an interactive feedback module connected to the first charging circuit, and the interactive feedback module is respectively connected to the load detection module and the central processing module; the load detection module is arranged between the first interface and the central processing module, the load detection module is used for sending the number of loads on any first charging circuit to the central processing module, and the central processing module instructs the feedback prompting submodule to send out prompting signals such as voice, characters or light according to the received signals of the load detection module. Or the load detection module indicates whether more than two first interfaces in any one first interface module are accessed to the load.
In particular, since the Type-a interface is generally adopted for the load that is commonly charged, in the case that each Type-a interface module includes several Type-a interfaces, particular attention should be paid to the voltage of the Type-a interface part to secure all the loads that access the Type-a interfaces. When more than two Type-A interfaces of any one Type-A interface module are connected with loads, namely a plurality of first loads, the AC/DC power supply module outputs the lowest voltage required by the communication protocol of the more than two loads, namely the plurality of first loads, through the Type-A voltage regulating module corresponding to the Type-A interface module, and distributes required power for the more than two loads, namely the plurality of first loads. At the moment, all loads of the Type-A interface module are indicated to be in a relatively quick charging state through the interactive feedback module through light or sound until a user only keeps a single load of the Type-A interface module, other loads are removed or transferred to other Type-A interface modules, and the interactive feedback module cannot indicate that all loads on the Type-A interface module are in a low-voltage charging state, so that each Type-A interface module is enabled to have only a single load and be in a quick charging state as much as possible, and the loads as much as possible are in the quick charging state.
Further, in order to safely access the load of the Type-a interface, the AC/DC power supply module is enabled to output the voltage required by the load through the voltage regulating module, and distribute the required power to the load, and the method further includes: the AC/DC power supply module outputs 5V voltage through the voltage regulating module, and after the central processing module normally receives signals of various load conditions, the charging processes of the Type-C interface part and the Type-A interface part are executed simultaneously and respectively.

If the loads comprise small micro devices, the AC/DC power supply module outputs the voltage required by the small micro devices through the Type-A voltage regulating module corresponding to any one Type-A interface module, and distributes the required power for the low-voltage low-current low-power devices. The Type-A voltage regulating module corresponding to the Type-A interface module adjusts and outputs (generally 5V) to other loads according to the voltage requirement of the small micro device, and reasonably distributes proper power to other loads.
It should be noted that the interactive feedback module can be connected to the Type-A voltage regulating modules of multiple loads through light or sound indication, so that a user is prompted to only keep a single load in the Type-A voltage regulating modules of the multiple loads, and other loads are removed or transferred to other Type-A voltage regulating modules, so that the Type-A voltage regulating modules as many as possible are connected to the single load, and the loads as many as possible are quickly charged.
3. If the Type-C interface and the Type-A interface are simultaneously connected with the loads, all the voltage regulating modules output 5V voltage, and after the central processing module frequently receives signals of the load conditions, the conditions of 1 and 2 are simultaneously and respectively executed.
