Generally, it is almost out of power after charging an ordinary mobile phone for 3 or 4 times, but now people are on business trips. For a variety of electronic digital products, the mobile power supply can't last long. It is often encountered that the mobile phone and other electronic products and the mobile power supply are out of power. At this time, there is no way to charge it, and the electronic equipment of the mobile phone cannot be used.

There are also battery treasures that can be charged by solar energy on the market now, but the charging time required for this type of mobile power supply is also different under different light intensities. The solar panels of mobile power supplies on the market are crystalline silicon panels, and crystalline silicon batteries The board contains both monocrystalline silicon and polycrystalline silicon. Among them, the photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, up to 24%, which is the highest among all types of photoelectric conversion efficiency. It also takes a long time to charge the mobile power supply under low light intensity. Sometimes it will be cloudy or rainy, and the light intensity in a day will not be very strong all the time, so the way of charging with solar energy also has its limitations.

Such as Chinese patent 201220455056.2, this kind of mobile power supply is designed with a mobile phone inserted into the card slot, which can fix the mobile phone on the surface of the mobile power supply, but the charging times of this kind of mobile power supply are limited. continue.

Such as Chinese patent 200620156250.5, this kind of mobile power supply has two silicon crystal plates to carry out solar energy charging to it, but its solar charging function of this kind of mobile power supply is almost useless in rainy and snowy days. Such as Chinese patent 201220368331.7, this kind of mobile power supply only provides the charging function, it is useless to make full use of the mobile power supply, and the function is too monotonous.
