快充手机能不能用普通手机充电器充电？你真的了解吗？快来看下吧
“快充”这个词我相信大家都不陌生，随着科技的进步，身边越来越多的手机都支持快充了，一些高端机都采用了44W或50W的快充技术，最快的能在30分钟充满电。大家都知道快充对手机电池有害，那么问题就来了，快充手机能用普通手机充电器充电吗？答案是肯定的，下面小编就站在专业的角度上给大家讲解一下！

那么什么是快充？
目前的手机快充技术有两种，分别是高压快充和低压快充。
高压快充一般指9V/2A或12V/2A的电源适配器进行充电，该种充电方式速度快，但也存在着容易发热的问题。主要应用此技术的有高通QC快充、联发科PEP快充。
低压快充顾名思义就是市面上的普通充电器，一般为5V/2A,5V/1A,5V/4A等。这种充电方式的优点就是发热低。
快充有三种实现形式：1、电压不变，提高电流。2、电流不变，提升电压。3、电压电流均提高。
手机要想做到快充，可不仅仅是把电压、电流提高就行了，还需要一套完善的电路、电芯、接口、数据线和适配器等，同时还需要做一套智能电源管理系统，让手机根据不同的场合，自行调节电压电流，以保证手机的正常充电！
那么快充手机能不能用普通的手机充电头呢？
答案是肯定能！快充手机所采用的技术不同，苹果手机一般采用的是pd快充协议，而华为采用的是fcp协议，小米和ov等一些品牌采用的是qc协议，所有的协议都伴有一个共同的特点，那就是向下兼容5v电压标准充电器，也就是说，你可以使用5v的低压充电器充电，充电速度会慢一点，但是电池更耐用！
总而言之，如果长期使用快充充电的话，会加快电池损耗，使用一年便不经用了。一般大多数人使用的都是5v2a的，不过一般情况下，大多数人还是会选择快充，因为好多时候都是因为用手机才会选择快充，那么如果是你的话，你会选择标准充电器还是快充充电器呢？欢迎在评论区留言！
