Problems solved by technology
The first method requires frequent disassembly of the battery, which consumes a lot of plastic components of the digital camera.
In the second way, when charging, the internal circuit of the digital camera is connected to the external power supply as a whole, which is easily affected by factors such as the unstable voltage of the external power supply, which reduces the life of the digital camera.
The first method also requires frequent disassembly, which will damage the memory card and card slot
The second method will cause loss to the digital camera data interface
