Problems solved by technology

However, at present, this wireless reverse charging technology for mobile phones is only used for temporary emergency power supply for mobile phones or other electronic devices. Its application range is small and it has not been widely used.

[0003] Lithium-ion batteries are commonly used in existing mobile communication devices, but the capacity of lithium-ion batteries will decrease in the cold outdoor conditions in winter in the north, especially in extremely cold conditions below -20°C, the use of lithium-ion batteries will be greatly affected. Under such conditions, the use of mobile phones will cause the mobile phone to automatically shut down due to the failure of the battery to supply power normally, which will cause inconvenience to use; the situation is more serious

[0004] The mobile phone case is a kind of protective case for wrapping and protecting the mobile phone, but the existing mobile phone case has a single function
