Multifunctional personal intelligent portable power source

Abstract

The invention provides a multifunctional personal intelligent portable power source. The multifunctional personal intelligent portable power source comprises a high energy battery and one or more than one USB interface for charging electronic products; the high energy battery is connected with one emergency USB interface, and is used for providing emergency charging for the electronic products. The portable power source also comprises a charging main circuit, and the charging main circuit can provide a charging power supply for the one or more than one USB interface; the input of the charging main circuit is 110 V to 240 V alternating-current commercial power, and the output of the charging main circuit is 5 V direct current. Alternating-current commercial power can be converted into 5 V direct current, and the power of the electronic products such as mobile phones is supplied through a plurality of USB interfaces such as four USB interfaces on the product, so that the design for a rapid charging circuit of the micro high energy battery is realized. Furthermore, the electronic products such as the mobile phones connected with the battery through the USB interfaces can be charged in the circuit through the battery in a plug-pull high energy lithium battery core. The self-designed charging main circuit is adopted, so that the circuit of a PCB is more compact. By adopting a layered and nested structural design, the product is more compact in size and flexible and easy to use.

Description

technical field [0001] The invention relates to a mobile power supply, in particular to a multifunctional portable personal intelligent mobile power supply. Background technique [0002] With the diversification of personal mobile terminals and the generalization of mobile office, the existing chargers can no longer be better and more widely applicable to the needs of consumers. For example, when people travel around, the existing chargers have The problem is often the shortcoming of not being able to find a suitable socket or the number of sockets is not enough; the current popular mobile phone travel power banks in the market all use USB ports. In terms of product design, if the existing products are simply superimposed, there is a problem that the volume is too large and it is inconvenient to carry. [0003] And miniaturization is not simply to improve the mechanical structure of the product. In the existing technology, most of them are solved by integrating imported IC ...

[0002] With the diversification of personal mobile terminals and the generalization of mobile office, the existing chargers can no longer be better and more widely applicable to the needs of consumers. For example, when people travel around, the existing chargers have The problem is often the shortcoming of not being able to find a suitable socket or the number of sockets is not enough; the current popular mobile phone travel charging treasures in the market all use the USB interface

In terms of product design, if the existing products are simply superimposed, there is a problem that the volume is too large and it is inconvenient to carry

[0003] And miniaturization is not simply to improve the mechanical structure of the product. In the existing technology, most of them are solved by integrating imported IC chips (such as: TI, MAXIN, Intersil, etc.). Large IC chips or multiple The use of IC chips makes the product circuit take up a lot of space
