The mobile phone screen is getting bigger and bigger, and the battery is getting more and more disabled. This is a trekking trip to the outdoors. The lack of power on the cell phone really means that it should not be called every day.
Booster Brolly charge umbrella.
It should be the idea of ​​a Chinese-American worker from Vodafone, Dr Tong, Kenneth Tong. The core of this invention is the so-called flexible solar cell, which can carry out a certain degree of bending. Therefore, when you go out to play, it will not only shave you, but also provide you with electricity. There are a total of 12 such flexible solar panels on the umbrella surface. They store the acquired electricity in the battery inside the umbrella handle and can fully charge the mobile phone in only 3 hours. And, even better, the top of the umbrella is equipped with a signal amplification device that can enhance the signal of all mobile phones within a radius of one meter!
