Problems solved by technology

[0002] At present, electronic devices with USB interfaces such as computers or mobile phones can use the charging function such as OTG (USB On-The-Go) function to charge other electronic devices with USB interfaces, but generally when charging external devices through USB interfaces The charging current is small, so the charging speed is relatively slow and the charging time is relatively long

Abstract

The invention provides electronic equipment, and the electronic equipment comprises a power supply which is used for providing electric energy for the electronic equipment; and a first charging unit which is connected with the power supply and connected with a first interface of the electronic equipment through a first switch. When the first switch is connected, the first charging unit is configured to charge peripheral equipment, connected to the first interface, at a first charging current. The electronic equipment also comprises a second charging unit, and the second charging unit is connected with the power supply and is connected with the first interface of the electronic equipment through a second switch. Moreover, when the second switch is connected, the second charging unit is configured to charge the peripheral equipment, connected to the first interface, at a second charging current. External charging electronic equipment serving as main equipment can carry out charging of equipment during shutdown. Moreover, a user can select quick charging or slow charging. When the user selects the quick charging, the electronic equipment can provide a larger charging current.

Description

technical field [0001] The present invention relates to an electronic device, and more particularly to an electronic device having a circuit structure of charging units with different charging currents. Background technique [0002] At present, electronic devices with USB interfaces such as computers or mobile phones can use the charging function such as OTG (USB On-The-Go) function to charge other electronic devices with USB interfaces, but generally when charging external devices through USB interfaces The charging current is small, so the charging speed is relatively slow and the charging time is relatively long. [0003] Moreover, the externally charged electronic device as the main device must be turned on to charge the external electronic device connected to it through the USB interface. After the shutdown, the external electronic device can no longer be charged through the USB interface. Charging, for example, when a user carries a notebook computer and a mobile phon...
