A cellular phone (cell phone, mobile phone, portable telephone) is battery-driven electronic communication equipment, which incorporates a battery in a main body to supply operating power needed by an electronic circuit. Cell phones have been regarded as the most important and influential personal communication equipment ever developed in the history. The cell phone is characterized in the convenience it provides in electronic communication, and it enables a user to keep contact with others at any place and at any time. Cell phones often combine communication, digital photography, and video game function, or communication, PDA, and video game function. Accompanying their ever advanced technologies, mobile phones are finding diversifying applications, such as a data (packet) communication terminal for carrying out emails, chatting and internet browsing, management of classified telephone directory and personal schedule data, as well as a game device and a digital camera. As mobile communications enters the age of 3G, high-speed and wide-bandwidth wireless communication capabilities become a need of mobile phones. Personal computers, personal digital assistants (PDAs), and notebook computers can wirelessly connect to the internet by using cellular phones. A cell phone includes a display part which is constituted of a liquid crystal display device and this display part displays pixel data having relatively large data quantity as well as time, a received incoming signal state, and a remaining battery quantity. A mobile phone is equipped with an internal power source comprised of a rechargeable battery set. The rechargeable battery set is charged by an external mobile phone charger that is plugged in an electric main. Generally, a cell phone battery charger charges a battery through a connection terminal at the rear of the battery. The charging connectors of the mobile phones of different brands are of different specifications, consumers have to change the mobile phone charger when they change mobile phones.
