Abstract

An electronic device includes an input power detection unit, a transmission control unit and a converter. The input power detection unit is configured to determine an input voltage value and an input current value of an input power. In response to the input power, the transmission control unit is configured to determine a first voltage value and a first current value associated with another electronic device via a handshake process. The voltage converter is configured to convert the input power, the first voltage value and the first current. A first power supply is provided and has the first voltage value and the first current value. The device is used for deal with the necessity of taking various voltage convertor or transformer in different specificities due to different charging requirement of different electronic apparatus in the prior art, and achieves power supply of determining a first maximum current as a first current value on the basis of the preset first voltage specficity, thus effectively completing power supply.

Description

technical field [0001] The present invention relates to the technical field of electric power detection, in particular to a power input detection device. Background technique [0002] In recent years, various handheld electronic devices have emerged rapidly. Although hand-held electronic products are easy to carry, they rely on batteries to provide power, and after the power stored in the batteries is exhausted, they are charged by charging devices. When charging a handheld electronic device, it must be equipped with a voltage converter or transformer of specific specifications, and the charging voltage of the voltage converter is fixed and cannot be adjusted with the electronic device. [0003] As the number of handheld electronic devices owned by individuals increases and the types tend to be diversified, the charging requirements and specifications of different electronic devices are not unified. In order to meet the charging demands of different electronic devices, man...
