华为要消灭充电宝！手机之间可实现互相充电，居然还有这种操作？
现在的手机几乎能够覆盖我们生活的方方面面，但是当手机没电的时候，其实跟一块砖头是差不多的。虽然现在很多手机品牌在研究手机电池容量扩大的事情，但是对于时时刻刻喜欢滑手机的人来说还是不够的。充电宝的发明让人们感受到了随身携带电量的安全感，只需要一根数据线就可把手机与充电宝连接起来。但是没带充电宝出门的话又怎么办呢？
之前突然出现个“反向充电”的操作，就是当手机没电时可以用别人的手机给自己的手机充电。“反向充电”和充电宝供电一样，也需要一根数据线，除此之外两部手机还需要用一条OTG线连在一起，OTG线能够满足目前市场上的手机使用“反向充电”功能。而华为更是出了一款“无线反向充电的功能”，这个功能可靠吗？
华为出的一款华为Mate 20 Pro手机，摒弃了用线来连接两部手机的做法。除了在自身内部内置4200mAh大电池、智能省电技术、快充功能之外，它还可以支持15w无线快充，就是无线反向充电技术。顾名思义，这个技术并不需要用线连接，只需要有两部手机就可以充电。
如果买到了这款手机的话，可以在这款手机的“设置”里找到“无线反向充电”开关，然后把这款手机和别的支持无线充电的手机背面贴在一起就能实现无线充电。虽然这种功能很方便，但是也只能救急而已，毕竟另一部手机的拥有者也不可能把电都给别人。
作为首部无线反向充电的手机，华为Mate 20 Pro的无线充电速度可达15w。目前还不知道它的速度多快，只知道它电量为594mAh，缓慢充电速度为2.5w。还有一个信息是无线反向充电这个功能如果长时间不用的话，手机会自动关闭这个功能，需要时再打开即可。
不过小编觉得这个技术虽然很厉害，但是安全隐患这种还是未知的，毕竟就算手机连接插座时也会有充电发热的迹象，更别说两台手机互充了。而且当手机之间互相充电的时候要贴在一起，两台手机就不能用了，不知道华为之后会怎么解决这两个问题。还是拭目以待吧，毕竟华为目前是我们国家最厉害手机品牌之一。
