A portable solar charger bearing the name "Blue Giant 28W" or "Big Blue 28W" won the title of best solar charger for smartphones, tablets and other portable devices, after a long race of competition and field tests that lasted three months, in which many chargers participated. Solar powered market.
The "blue giant" won the title after topping the list of the best solar chargers on the market, which included five other solar chargers.
The tests were carried out by a team of analysts of the digitaltrends.com website, in various areas of solar brightness, during the multiplication of clouds, and the clearness of the sky, and during the different climatic conditions, between cold, rain, wind and other, and at different times during the day, since sunrise. Until sunset.
The results of the tests were published on January 23.
Analysts emphasized that the development of solar chargers put on the market makes them an effective, practical and easy alternative, to provide renewable and clean energy for smartphones all the time, in different circumstances and regions, and the tests ended with the selection of six models, as they are the best, and the list came as follows:
