In order to provide some help and reference for those who are planning to buy solar chargers, this article will let everyone know more about solar chargers. Let’s take a look at the purchase and use of solar chargers. Look at the three disadvantages of solar chargers.

 

First: Low conversion rate

 
The conversion rate of commercial solar panels is still relatively low, generally only 14-16%, and the best solar charger conversion rate is only 23%. Therefore, the key to the conversion rate lies in solar panels.

 

Second: the charging speed is slow

 
The larger the area of the solar panel, the more sunlight will be absorbed and the faster the charging speed. It is recommended to use a folding solar charger for easy carrying; in addition, the intensity of sunlight will affect the charging speed.

 

Third: can not store electricity, not practical

 
Some products do not have their own energy storage batteries. In other words, you must charge while you are in the sun. Leaving the strong sunlight, the product can be said to have failed. However, the solar charger of the energy storage cell will also increase in weight and volume, so as to ensure charging even when there is no sun.

 

3 disadvantages about solar chargers
 
It is recommended to use a solar charger in combination with a charging treasure. You can use the solar charger to fill the charging treasure first, then charge the phone.

 

principle
 
The solar charger converts the solar energy input into electric energy through the solar panel, and then uses the MC chip to realize the DC/DC voltage reduction, and converts the electric energy converted by the solar energy into a stable direct current electric appliance to be charged, and matches the charging product. The best voltage will not cause damage to the charging product. Its main purpose is to use spare batteries for traveling, traveling, hiking, etc. It can be used for charging mobile phones, mp3, mp4, psp, gps, digital cameras, portable audio and video equipment.

 

Type of solar charger

 
With the development of technology, there are many types of solar chargers used in different fields. Solar mobile power sources are mainly divided into two categories:
 

1: There is a function to store power. The solar charger is a new type of power source that is stored in a battery after converting solar energy into electric energy, and is convenient to carry a portable device that can supply power to a mobile phone and the like, and has a movable property.
 

2: Green products: no function of saving electricity. The general power is greater than 6.5W and less than 40W. Powered by direct charging of power receiving equipment.
 

Conclusion: For those who are often outdoors, solar chargers are a good choice, but they can’t rely on it. For a long time, it is recommended to combine solar chargers with charging treasures. Do not blindly purchase and use friends who need it. When purchasing, you need to purchase according to the actual situation (power size) of the required charging products. Please read the product manual carefully before use.
