The method is mainly characterized in that charging voltage, current and power cover a wider range, physical channels and communication modes of quick charging communication are various, and charging strategies and control processes are different. In order to meet the diversified demands of different charging devices, the USB charging port often needs to perform communication negotiation with the charging device, and allocate self resources to achieve an optimal charging strategy with the charging device according to the current working state.

However, in most applications, not all outlets of the multi-port charger are operated at full load, and if each outlet of the multi-port charger is to allocate resources according to an independent operating standard, the cost and volume of the charger are often unacceptable, and even unnecessarily wasted in many applications.

In addition, the mobile energy storage power supply represented by the mobile power supply and the outdoor power supply not only supports a plurality of output ports to carry out output power supply for the charging equipment, but also supports a plurality of input ports to carry out input charging for the charging equipment. In the design and application process of such devices, input and output properties of each USB port often need to be configured.
The diversification of charging equipment, the differentiation of quick charging protocols and charging strategies, the universality of application scenes and the complexity of consumer use habits bring forth various demands on the performance and specifications of multi-port quick charging equipment.
