As shown in fig. 1 to 4, the present embodiment provides a mobile charger, which includes a controller, a first output port, a second output port, and a third output port, wherein the controller is a controller based on a fast charging protocol, such as a QC3.0 protocol, and intelligently adjusts an output voltage according to an "optimal Intelligent voltage adjustment" (INOV) algorithm thereof, so as to provide flexible switching between voltage levels of 5V and 20V, that is, an output control logic or an output control method of the charger can be designed based on the protocol. The controller is electrically connected with the first output port, the second output port and the third output port and is used for controlling the power output of the first output port, the second output port and the third output port; when one of the first output port and the second output port is in an output state and the third output port is in a non-output state or the output power is lower than a preset power value, the output power of the first output port or the second output port in the output state is the first power, in this embodiment, the first power is 65W, specifically, when only one device is charged and the charging device is only connected to the first output port or the second output port, that is, the charger outputs the maximum charging power of 65W through a single port. The preset power in this embodiment is 1.5W, specifically, after the charging device is fully charged, the charger is in an idle state in which charging is stopped, that is, at this time, the occupied load of the charging device connected to the output port on the output port does not exceed 1.5W, and it can be regarded that the charging output port is in a no-output or no-load state. When the first output port and the second output port are both in a non-output state and the third output port is in an output state, the output power of the third output port is the second power, the second power is smaller than the first power and larger than the preset power value by 1.5W, and the second power in this embodiment is 18W or 22.5W. That is, in this embodiment, the third output port is a low power output port, so that the charger can charge the access low power charging device alone. When one of the first output port and the second output port is in an output state and the third output port is in an output state, the third output port outputs the second power of 18W or 22.5W, the output power of the first output port or the second output port in the output state is the third power, and the third power is smaller than the first power of 65W and larger than the second power, the third power in this embodiment is 45W, that is, the first output port and the second output port in this embodiment may perform power distribution according to the charging voltage applied by the accessed charging device; for example, when the first output port and the third output port are both connected to the charging device, the controller broadcasts the WPDO of 45W +18W, or broadcasts the WPDO of 45W + 22.5W; for another example, when the second outlet and the third outlet are both connected to the charging device, the controller broadcasts the WPDO of 45W +18W, or broadcasts the WPDO of 45W + 22.5W.
As shown in fig. 1 to 4, in a preferred embodiment, when the first output port is in the output state first, the second output port is in the output state later, and the third output port is in the non-output state or the output power is lower than the preset power value of 1.5W, the output powers of the first output port and the second output port are the fourth power and the fifth power, respectively, the sum of the fourth power and the fifth power is less than or equal to 65W of the first power, and the fifth power is less than the fourth power. In this embodiment, the first power is 65W, the fourth power is 45W, and the fifth power is 18W. Specifically, when only the first output port and the second output port are connected to the charging device, the controller broadcasts the WPDO of 45W + 18W; that is, when only the first output port and the second output port are connected to the charging device, the first output port is a default high-power output port, so that the first output port is preferred according to the use habit, and the function of setting the second output port as the default high-power output port is the same.
As shown in fig. 1 to 4, in a preferred embodiment, when the first output port, the second output port and the third output port are all in an output state, the output powers of the first output port, the second output port and the third output port are respectively sixth power, seventh power and eighth power, wherein the eighth power is less than or equal to 22.5W or 18W of the second power and is greater than a preset power value of 1.5W, one of the sixth power and the seventh power is equal to the eighth power, one of the sixth power and the seventh power is greater than the eighth power, and the sum of the sixth power and the seventh power is less than 65W of the first power. In this embodiment, the eighth power is 18W, and one of the sixth power and the seventh power is 30W when being greater than the eighth power, and the other is 18W. When the first output port enters the output state before the second output port, the sixth power is 30W which is greater than the seventh power, and when the first output port enters the output state after the second output port, the sixth power is 18W which is less than the seventh power. In a preferred embodiment, the sixth power is 18W equal to the eighth power, and the seventh power is 30W greater than the eighth power and the sixth power. For example, when the charging device is connected to the first outlet, the second outlet and the third outlet, the controller broadcasts the WPDO of 30W +18W, or broadcasts the WPDO of 30W +18W +22.5W, or broadcasts the WPDO of 18W +30W + 18W.
In a preferred embodiment, the first output port and the second output port are of the same Type, the third output port and the first output port and the second output port are of different types, preferably, the first output port and the second output port are USB Type-C interfaces, and the third output port is a USB Type-a interface or a USB Type-B interface. The Type-C interface can support the insertion of the front side and the back side, so that the use convenience of the charger is improved; meanwhile, the Type-C supports the USB fast charging power supply standard, and the maximum power supply power can be supported to 100W.
In a preferred embodiment, the mobile charger is a mobile phone charger or a tablet computer charger or a notebook computer charger.
