Problems solved by technology

[0003] The main source of power for electronic products comes from the supply of electricity, and portable electronic products such as mobile phones and digital cameras rely on batteries to provide power for driving. It is used to charge the battery of the portable electronic product, and the existing chargers can only be plugged into the socket of the mains to provide power for the battery to be charged. However, the indoor distribution of the mains socket is limited, and There are a large number of electronic products. Therefore, even if the charger is indoors, there will often be no mains socket for plugging in. Not to mention that when going out, the mains socket is not easy to obtain, and the rechargeable battery of portable electronic products often occurs. When the power is used up, but the mains outlet cannot be found for charging, so that the portable electronic product with the battery cannot be used
