In recent years, self-driving tours and outdoor sports have been deeply loved by everyone, and the power of electronic products such as mobile phones has always been a big problem. Although there are power banks, they can’t be supported by continuous use of mobile phone power banks. The traditional power bank cannot solve the energy problem, so solar chargers came into being. For this reason, more and more people use solar chargers.
In order to provide some basic help and reference to those who are planning to buy solar chargers, this article can let everyone know more about solar chargers. Let us take a look at before buying and using solar chargers. Look at the three major misunderstandings of solar chargers.
Misunderstanding 1: Low conversion rate
The conversion rate of market-oriented solar panels is still relatively low, generally only 14-16%, but we use imported SUNPOWER solar panels and LG solar panels, the conversion rate is as high as 23%. Therefore, the key to the conversion rate lies in solar panels.
Misunderstanding 2: The charging speed is slow
The larger the area of the solar panel, the more sunlight it will absorb and the faster the charging speed. It is recommended to use a foldable solar charger for easy carrying; in addition, the intensity of sunlight will also affect the charging speed.
Misunderstanding 3: Cannot store power, not practical
Some products do not come with energy storage batteries. In other words, it must be charged while basking in the sun. Without strong sunlight, the product can be said to be invalid. However, the weight and volume of solar chargers for energy storage batteries will also increase, so that they can be charged even when there is no sun.
It is recommended to combine the solar charger with the power bank. You can use the solar charger to fully charge the power bank (mobile power) before charging the mobile phone. This method is especially suitable for long-term stationed in a certain place.
principle
The solar charger converts the light energy input from the solar energy into electric energy through the solar panel, and then uses the MC chip to realize the DC/DC step-down, and the electric energy converted from the solar energy is converted into a stable direct current through the circuit to charge the electrical appliance, matching the charging product The best voltage will not cause damage to charging products. Its main purpose is to spare batteries when going out, traveling, climbing, etc., which can be used to charge mobile phones, mp3, mp4, psp, gps, digital cameras, portable audio-visual equipment, etc.
Types of solar chargers
With the development of technology, there are many types of solar chargers used in different fields. Solar mobile power supplies are mainly divided into two categories:
1: With the function of storing power. The solar charger is a new type of power source that converts solar energy into electricity and stores it in a battery, which is convenient to carry and can supply power to portable devices such as mobile phones.
2: Green environmental protection products: there is no function of saving electric energy, and the power is more than 6.5W and less than 40W. On the power receiving equipment that generates direct charging.
Conclusion: For those who are often outdoors, the solar charger is a good choice, but you can't rely on it. It is recommended to use the solar charger and the power bank in the outdoor for a long time. Friends in need do not buy and use blindly. When purchasing, you need to choose according to the actual situation (wattage) of the required charging product. Please read the product manual carefully before use
