In this embodiment, the installation area 221 is set to two, for installing two 1.5V batteries to supply power to a device with a power consumption voltage of 3V. At the same time, the control component 3 in this embodiment can convert the high voltage of the mains power into a low-voltage direct current with a maximum output of 3V required by the device. This setting ensures that the adapter body 1 can supply power to the device normally in the power-off state. Further, in some other embodiments, the installation area 221 can be set to four or six, and at the same time, the control component 3 in these embodiments can convert the high voltage of the mains power into a low-voltage direct current with a maximum output of 6V or 9V required by the device correspondingly.

In this embodiment, the first replacement part 51 is arranged in the shape of a No. 5 battery, so that it can be applied to various devices that need to be powered by No. 5 batteries. This setting improves the adaptability of the first replacement part 51. Further, the setting of the docking end 56 enables the first replacement part 51 to be stably connected to the adapter body 1, thereby realizing stable power supply conversion. Further, in this embodiment, the first connection end 54 serves as the positive electrode and contacts the positive electrode of the device, and the second connection end 55 serves as the negative electrode and contacts the negative electrode of the device. When the first replacement part 51 is inserted into the battery slot of the device, the output current of the adapter body 1 forms a loop through the first connection end 54, the device, and the second connection end 55, realizing the same circuit connection as the traditional battery. This setting effectively simulates the working mode of the traditional battery, enabling the device to operate normally.
