Abstract

The invention provides electronic equipment, which is applied to the technical field of computers. The electronic equipment comprises a shell, a USB (Universal Serial Bus) interface, a power supply device and a switching device. When the electronic equipment is powered off, a user can connect or disconnect the power supply device with the USB interface through the switching device, so that external electronic equipment can be charged by the USB interface when the electronic equipment is powered off. The electronic equipment is further provided with a voltage adjusting device, so the output voltage of the USB interface can be further adjusted, various charging choices can be provided for users, and the charging function of the electronic equipment under various voltages is further realized.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to an electronic device. Background technique [0002] At present, electronic devices based on the USB interface are more and more widely used, and as a typical PC supporting the USB, it has even more popular applications. However, when the device is turned off, it cannot be charged through the USB interface, and the voltage requirements of the devices that need to be charged are not the same when charging. Therefore, when the voltage of the device that needs to be charged changes, the electronic device cannot be charged device to charge. Contents of the invention [0003] In order to solve the problem that the external device cannot be charged through the USB interface of the electronic device when the electronic device is turned off. Therefore, the present invention provides an electronic device, so that when the electronic device is turned off, the user can determine the vo...
