Description

technical field [0001] The present application relates to the technical field of charging, in particular to an adapter device and an electronic device. Background technique [0002] With the development of technology, the application of "fast charging" when charging electronic devices is becoming more and more common. The adapter device, as an intermediate device connecting the power supply and the electronic device to be charged, also needs to be improved accordingly. [0003] For existing adapter devices with multiple output ports, the output power of the output port is relatively high during fast charging because the total output power has a certain upper limit, and the sum of the output power at multiple output ports cannot exceed the limit of the total output power Under the circumstances, when multiple electronic devices are connected to the adapter device, the "fast charging" strategy cannot be implemented for each electronic device. The existing method is generally b...

[0003] For existing adapter devices with multiple output ports, the output power of the output port is relatively high during fast charging because the total output power has a certain upper limit, and the sum of the output power at multiple output ports cannot exceed the limit of the total output power Under the circumstances, when multiple electronic devices are connected to the adapter device, the "fast charging" strategy cannot be implemented for each electronic device. The existing method is generally by setting a protocol chip at each output port and configuring the protocol chip as The main protocol chip and the slave protocol chip further implement the information synchronization between the master protocol chip and the slave protocol chip by formulating corresponding communication protocols to identify whether the corresponding output port has electronic equipment connected. This method needs to set strict Communication protocol and high cost
