Let me tell you the simplest thing: although solar energy can now be widely used, have you seen power plants that use solar energy to completely replace coal-fired electricity generation?
The main selling point of solar power banks is their novelty, but in reality their quality is very poor. Serious false capacity standards, slow charging, low power conversion rate and too fast discharging are common characteristics of all solar power bank brands. What can this diet be used for? The most economical is to buy a more reliable lithium battery power brand.
The price of ordinary solar power banks is between one hundred and two cents. There is only one solar panel and the solar charging power is low. Pure solar charging may take a week, which cannot meetto the demand for electricity. Users It must also be charged by connecting to the mains. This kind of solar power bank is no different from ordinary power banks.
The price of quadruple solar power bank is between three and four cents. , and it has four solar cells after unfolding. The battery panel greatly improves solar charging efficiency. According to the test, it can be fully charged in about 6 hours using pure solar energy. It won the gold medal in the 2015 Chinese Characteristic Tourism Product Selection. If you choose solar energy, you should choose this one.
