手机闪充技术进步！但和普通充电比，闪充真的不会伤害手机吗？
随着时代的快速发展，人们的生活节奏变得越来越快。现在人们普遍都使用手机，当手机没有电时，每个人都想能快速充上电，最好可以在最短的时间内获取最大的电量。闪充这个技术也是近几年才出现的，很多人对这门新技术抱有质疑，快充是否会对手机产生伤害？
实际上，快速充电的快速也是相对于普通充电来说的。一般的5V2A的充电头是普通充电，而快速充电就是在提高电压这方面来减少时间提高充电速度，5V2A，这是较安全的快充。
一般的家庭线路的电压是220V，手机充电一般都需要通过充电器降压，在手机充电时还需要在手机内部进行第二次降压处理。而快速充电就是例外，比如9V2A，这样的快速充电为了达到速度，需要提高电压。一般的普通速度充电时，充电器发热的温度不会高，而快速充电时，提高了电压，这样的话，充电时充电器就会发热。当然这样的现象是不好的。
而手机里的芯片就派上了大用场，它可以降低充电的速度来缓解发热。4.5V5A，这样的快速充电器可能会与以后旗舰机搭配。这类型的快充的充电速度非常快，在速度上非常符合大众的要求。但是这样的快充充电时发热也是最大的，由于手机内部的二次降压的幅度较小，所以在充电时发热的问题得到了解决。5V2A，这一款充电器发热稍稍偏高，并且速度也不是很快。
很多人都会好奇，使用快充会给手机带来怎样的影响呢？举个例子，如果手机应该用的是9V2A这个充电器，但是却使用了5V2A的充电器，这样的话，手机的发热会缓减，但是它的速度也会降下来 自始至终都不会对手机的部件造成任何不好的影响。
如果手机应该是用4.5V5A充电器，要是用5V2A的充电器来充电，那么手机在充电时会发热，并且充电的速度也会慢很多。实际上，使用快充和慢充只是会影响充电时的热度和速度，并不会伤害手机内部的部件。快充和慢充除了速度之外也没有多大的差别。
其实，手机普通充电的速度并不慢，只不过现在很多人都习惯了快速的生活，由此手机厂商研发出了快充，符合了大众们对快节奏生活的需求。快充在手机没电时，但是急需要用手机的时候的作用才是最大的，除了速度，快充与慢充其实没有什么区别。
