	&nbsp; &nbsp; 苹果18W的USB C充电器大家都知道，也是已经市场经常可见的了，高仿的也是已经竞争很激烈了。对于20W新的快充充电功率，和18W的USB C充电器后续的走向也是在摸索。

	对于QC4.0快充协议，很多人还是模糊的，或许是高通的宣传不够，搭载的手机太少。 


	日常中，很少听到QC4.0快充协议，甚至QC4.0+快充协议了，目前来说，因为苹果11的USB C PD 18W充电器出现大家都把目光放在了USB PD快充协议这上面来. 


	对于QC4.0,QC4.0+的关注自然降到了最低。

	&nbsp;充电器的D+,D-为什么常常看到加了电阻？


	


	&nbsp;其实，这个D+,D-加的电阻是为了给手机，平板等提供信号检测用的。一般叫分压电阻。


	&nbsp;不同的阻值的电阻，D+.D-的电压也是不一样，手机，平板就是通过检测识别D+,D-的电压来检测判断充电器状态的动作。
