A multifunctional flexible solar panel portable charging device

Abstract

The invention relates to a multifunctional and portable charging device with a flexible solar panel. Even though the illumination is poor, large current output under stable 5V voltage can be achieved normally, an internal battery pack and an external electronic product can be charged rapidly, and the charging speed is improved by 50% than that of a conventional solar charging device. Under the condition of lack of sunlight for a long time, an electric supply can serve as electricity to be input through a USB interface, so that normal using of various functions is ensured. Meanwhile, as a practical locking device and an automatic containing device are adopted, the flexible solar panel is unfolded, fixed and folded and can be drawn out conveniently and rolled up automatically, the portable charging is convenient, and charging batteries of electronic products such as mobile phones, MP3s, MP4s and digital cameras can be charged rapidly. One switch can control various working states of alarm and lighting, the device can also be used as a flashlight or an alarm device, and the device can be used as a camping floodlight in camping in the wild.

Description

technical field [0001] The invention relates to a solar charging device, in particular to a multifunctional flexible solar panel portable charging device, which belongs to the application field of photoelectric technology. Background technique [0002] Most of the various electronic products now use rechargeable batteries, which need to be charged in time when the power is insufficient. Solar energy is a widely existing clean energy, therefore, charging devices based on solar energy have been widely used. The known solar charging devices all use various types of solar panels as solar receivers, convert light energy into electrical energy through the photovoltaic effect, and output it through an external auxiliary circuit to provide electrical energy supplement for electronic products. [0003] The portable solar charger of patent No. 02243162.4 is characterized in that: on the same side of several plastic plates that are connected to each other and can be folded in an "M" s...

AI Technical Summary

Problems solved by technology

[0007] To sum up, the existing solar charging devices used outdoors and in the field have the following main problems: first, the solar panels have a small light-receiving area and low output power; Larger, not convenient for personal carrying; third, the charging current is small and the charging speed is slow; fourth, the function is single, and it cannot take into account various outdoor and field practical needs at the same time, such as charging, lighting, alarm and other functions
