Background technique

With the intelligent development of mobile devices in the field of digital product technology, in order to ensure portability, the built-in lithium batteries of mobile devices are relatively small. It is difficult to meet the usage requirements of the equipment, and the mobile phone often fails to work properly due to power attenuation midway. Therefore, various mobile power sources continue to appear in the field of vision of consumers. Since the charging interfaces of the products produced by major mobile phone manufacturers are different, the mobile power banks that charge smartphones are also incompatible. When going out, smart phones and tablet computers cannot continue to work due to power attenuation in the middle, and there is no available power supply or charging equipment, which will bring great inconvenience to people using smart phones.

Contents of the invention

The purpose of the utility model is to provide a mobile power supply which is simple in structure, easy to use, and suitable for various brands of smartphones, and solves the problem of charging smartphones when there is no available charging power supply.

The technical scheme adopted by the utility model is that a mobile power supply for a smart phone includes an upper cover and a lower cover of the housing of the mobile power supply. In the housing of the mobile power supply, a The charging module is connected to the lithium battery, and the charging module is respectively connected to the power monitoring module and the boost module provided on the printed circuit board; the power monitoring module and the boost module are respectively connected to the LED display module and the smart machine identification module.

The mobile power supply for smart phones described in the utility model is also characterized in that:

The input and output ends of the printed circuit of the printed circuit board are respectively connected with USB input and output interfaces.

The upper cover of the housing exposes a power indicator light provided by the LED display module. .

The mobile power supply of the smart phone of the utility model charges the lithium battery through the charging module through the USB input interface, and monitors the remaining power of the lithium battery in real time through the power monitoring module, and then sends the monitored power signal to the LED display module to make the power display light glow. When the lithium battery is fully charged, the smartphone can be plugged in through the USB output interface, and the brand of the smartphone can be identified through the smartphone identification module, and then the voltage and current parameters required by the corresponding equipment can be simulated and output to the smartphone for charging. The smart phone provides a suitable mobile power supply, which solves the problem of charging the smart phone when there is no available charging power.
