有小伙伴是第一次接触笔记本电脑，接触到很多的硬件都是比较陌生的，比如标配的笔记本适配器等，就不知道笔记本适配器是什么，笔记本适配器有什么功能等。今天小编就给大家详细介绍下相关的内容。
工具/原料：
系统版本：windows10系统
品牌型号：戴尔灵越13
一、笔记本适配器是什么
笔记本适配器，简单来说就是笔记本电脑的充电器。传统笔记本充电器只能输出单一的电压给一型号的笔记本电脑充电，因此这类电源适配器被称为单波段笔记本充电器。
笔记本适配器是小型便携式电子设备及电子电器的供电电源变换设备，一般由外壳、变压器、电感、电容、控制IC、PCB板等元器件组成。
二、笔记本适配器有什么功能
笔记本适配器的工作原理是把不稳定的电源利用开关电源的原理，通过转化电路变成笔记本电脑需要的恒压直流电，给笔记本电脑供电和充电。
不过要注意的是，适配器的输出电压和电流是不一样的，所以各个笔记本选用适配器时必须注意，最好使用原配适配器。
三、笔记本适配器接口有哪几种
1、笔记本电源接口一般常见的有圆形电源接口、方形电源接口、USB Type-C电源接口。注意，方形电源接口不全是USB接口，圆形接口最为普遍，因为规格的不同，圆形接口的孔径也有所差异。
2、USB接口是电脑中最常见的接口，目前常见的USB接口有USB 2.0、3.0、3.1版本，版本越高代表速度越快，但是也有特殊情况，比如USB 3.1 Gen 1的速度就和USB 3.0一样，都是5Gb/s。
3、常见的USB接口外观有Type-A和Type-C两种，Type-A最为常见，Type-C是近几年流行起来的接口，Type-C最明显的优势就是支持正反插，不用看接口是否插错，非常方便。
总结：
以上便是关于笔记本适配器的含义以及相关的功能和接口介绍，对于初学者不懂电脑适配器的网友来说，可以收藏方便学习了解哦。
