Abstract

The invention discloses a device for taking a mobile phone as a power supply. A power supply circuit board is directly adhered to a mobile phone backboard, and an electric quantity output port is usedas a new USB interface to be installed on the side surface of the mobile phone and is covered by an adhesion piston; the power supply circuit board comprises a battery cell connected with a boosted circuit and a charging circuit respectively, the boosted circuit is connected with an input end, the charging circuit is connected with an output end, the input end is connected with an input port of the mobile phone, and the output end is connected with electronic equipment needing charging. According to the invention, new applications of the mobile phone are increased, and when the mobile equipment serves as more and more comprehensive functions in life, new possibility and substitutability are increased for the functions of the mobile phone.

Description

technical field [0001] The present invention relates to the field of mobile device charging, and more specifically, relates to the reverse charging of electronic technology mobile terminals. Background technique [0002] With the improvement of people's living standards and the advancement of communication methods, mobile phones have become an indispensable and portable item for people. The phone stores power, but cannot power other electronic devices. If the mobile phone has sufficient power and other electronic devices (such as another mobile phone) need power, the mobile phone can be charged in reverse and used as a charging device to charge it, which will provide great convenience for users. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to solve the emergency power consumption situation of tiny electronic devices, and provide a device that uses the mobile phone as a "power bank analogue" and realizes the mobi...
