The second control unit 220 can be connected to the second interface 20 through the third power supply line P3 to transfer power between them.

[0040] In some embodiments, the second control unit 220 is electrically connected to the communication pin in the second interface 20 via the third communication line C3, and when the second interface 20 is connected to the first interface 10 of the portable load 1 and the charging adapter 2 charges the portable load 1, the communication pin in the second interface 20 is electrically connected to the communication pin in the first interface 10.

[0041] Please refer to the following: Figure 1 When the charging adapter 2 charges the portable load 1, the portable load 1 outputs first information to the second interface 20 through the first interface 10. The second interface 20 then transmits the first information to the second control unit 220 via the third communication line C3, causing the second control unit 220 to drive the display unit 22 to display the first information. Furthermore, the second information provided by the first control unit 21 is also transmitted to the second control unit 220 via the second communication line C2, causing the second control unit 220 to drive the display unit 22 to display the second information.

[0042] Please see Figure 2 , Figure 2 This is a schematic diagram of the circuit structure of the charging adapter according to the second preferred embodiment of this case. The charging adapter 2a of this embodiment and... Figure 1 The charging adapter 2 shown has a similar structure, so it will only be represented by the same symbol and will not be described in detail again. However, in this embodiment, the charging adapter 2a does not include... Figure 1 Instead of the third communication line C3 and the third power supply circuit P3 shown, a fourth communication line C4 is included. The fourth communication line C4 is electrically connected between the first control unit 21 and the second interface 20, so that the first control unit 21 can transmit signals to the second interface 20 through the fourth communication line C4. When the second interface 20 receives the first information from the first interface 10, it can transmit it to the first control unit 21 through the fourth communication line C4.

[0043] In some embodiments, the second control unit 220 is electrically connected to the TX communication pin in the second interface 20 via the fourth communication line C4, and when the second interface 20 is connected to the first interface 10 of the portable load 1 and the charging adapter 2 charges the portable load 1, the TX communication pin in the second interface 20 is connected to the RX communication pin in the first interface 10.

[0044] Please refer to the following: Figure 2 When the charging adapter 2a charges the portable load 1, the portable load 1 outputs first information to the second interface 20 through the first interface 10. The second interface 20 then transmits the first information to the first control unit 21 through the fourth communication line C4. The first control unit 21 then transmits the first information to the second control unit 22 through the second communication line C2, so that the second control unit 220 drives the display unit 22 to display the first information. In addition, the second information provided by the first control unit 21 is also transmitted to the second control unit 220 through the second communication line C2, so that the second control unit 220 drives the display unit 22 to display the second information.

[0045] In some embodiments, when Figure 1 The charging adapter 2 shown or Figure 2 When the charging adapter 2a shown is only connected to the portable load 1 and not connected to a power source, the display unit 22 of the charging adapter 2 or the display unit 22 of the charging adapter 2a can be powered solely by the portable load through the power transmission path of the first power supply line P1, the second power supply line P2, the second interface 20, and the first interface 10. In this application scenario, the portable load must be a device with an energy storage unit, such as a laptop or mobile phone with a battery; and the second control unit 220 in the display unit 22 only processes the first information and drives the display unit 22 to display only the first information. Figure 1 The charging adapter 2 shown or Figure 2 When the charging adapter 2a shown is only connected to the power source and not connected to the portable load 1, the second control unit 220 in the display unit 22 only processes the second information and drives the display unit 22 to only display the second information.

[0046] In summary, this invention provides a charging adapter that not only converts electrical energy from a power source to charge a portable load, but also displays first information about the portable load and / or second information about the charging adapter. Therefore, it fully utilizes the functions of the display module of the charging adapter and has better practicality.
