On November 1st, the massive use of mobile phones worldwide has brought a serious environmental problem - the disposal of used cell phones. Many people throw away the bad batteries directly, but they do not think this will cause much damage to the environment. Therefore, the search for other clean and pollution-free mobile phone charging methods has become a method for many scientists to try to solve the problem of mobile phone batteries. The Kalhuohfummi solar charging system is a charging device that uses solar energy to provide power for mobile phones.
Kalhuohfummi charging equipment includes a solar cell and solar template Maraoshi. The use of clean and free solar power generates environmental protection without pollution.
Kalhuohfummi is a power source for storing your electronic devices while Maraoshi is a flexible solar module that can deliver up to 4 watts per hour and can provide Kalhuohfummi solar cells with four hours of sufficient power.
This Tianyang energy charging device is priced at US$149, which is about 950 yuan. It will be officially sold on November 15.
