The principle of solar phone charger is to convert solar energy into electric energy stored in solar phone charger. The key to the quality of the solar phone charger is four points: one, use efficiency. The use efficiency includes two aspects: the transformation efficiency of solar panels and secondary conversion efficiency.
The conversion efficiency of the solar panel means that the light energy is converted into electrical energy; and the secondary conversion efficiency refers to the efficiency of the light energy to store the battery after converting into electrical energy. Second, battery quality and capacity. Battery capacity is generally 1.
2 times for your mobile phone battery. Solar built-in lithium-ion battery discharges to digital products such as mobile phones. There will be energy loss during energy conversion, and the conversion rate is generally 80% -90%.
The battery so solar energy is enough for your mobile phone, such a large battery can Your mobile phone battery. And the quality of the battery is also related to the life of the solar charger. Third, control circuitry and protection circuit.
The current solar phone charger products in the market are very complicated. It protects circuits and control circuits may be simple design, or poor compatibility, it is easy to let go of mobile phones or decrease the service life of mobile phones and batteries. Therefore, the design of control circuit and protection circuit is very tight.
Fourth, solar charger accessories. This issue often is often ignored by many users, but it is not to neglect. There are adverse suppliers in the market to configure inferior fittings for price advantages, such as AC chargers (common famous fire cattle), AC charger has two IC protection circuits or no IC protection circuit.
AC charger without protecting IC is not only small charging current, but the long-term charging time is not good, and the whole hidden danger. Special attention should be paid to the purchase of solar chargers, and the AC charger is not protected by circuit IC. Solar mobile phone charger can only be used in a hurry, can not completely rely on it to charge digital products such as mobile phones, to achieve full mobile phone charging, the general mobile phone must have solar phone charger's solar panels greater than 0.
