So I made this video because all the videos you have seen on YouTube are fake videos. You know there is no such thing as free energy. Because you have also read in the book. So I made this video for you to prove that all the videos you have seen are fake. Hope you understand.
Stop watching these full videos, you can follow my channel if you want to see real videos or original videos.

00:00为什么一定要拔手机充电器?
00:02我们来看一下
00:03线路上没有负载时,我们用前行电流表去测,是没有电流的
00:11插上手机充电的状态下,我们再测一下它的电流
00:16前行表显示是96.4M,拔掉正在充电的手机
00:23再测一下它的电流,显示是6.84M
00:29充电器就算不连接手机也处于工作状态,一直插着也会浪费电,长时间插着会持续发热,加速远近老化,容易短路引起火灾
00:37有些充电接口,这个外漏部分是有电的,会引起发热,长时间接触,皮肤会出现烫伤,如果接触易燃物品,甚至会引起火灾
00:48我们打开一个充电器,看一下里面,充电器里面有线圈,电容,芯片,充电器一直处于待命状态,这些元件就要维持电压,检测有没有手机插进来
01:00就算不充电,插着充电器,它也会耗电,看过很多案例,由于充电器引起的火灾,把家都给烧没了
01:08了解了不拔充电器的危害,以后记得拔掉充电器,关注每天分享电工知识
