電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)又稱外置(zhi)電(dian)(dian)(dian)(dian)源(yuan)(yuan)，是一(yi)種小型便攜式電(dian)(dian)(dian)(dian)子(zi)設備及電(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)器(qi)(qi)的(de)供(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓變(bian)換設備，由外殼、變(bian)壓器(qi)(qi)、電(dian)(dian)(dian)(dian)感、電(dian)(dian)(dian)(dian)容、控制IC、PCB板等元器(qi)(qi)件組(zu)成(cheng)，它的(de)作(zuo)用(yong)主要是：將電(dian)(dian)(dian)(dian)流(liu)(liu)由交流(liu)(liu)輸入轉換為直(zhi)流(liu)(liu)輸出，把不穩(wen)定的(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)通過(guo)轉化電(dian)(dian)(dian)(dian)路變(bian)成(cheng)電(dian)(dian)(dian)(dian)子(zi)產(chan)品需(xu)要的(de)恒壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)，從而給物(wu)體供(gong)電(dian)(dian)(dian)(dian)和充電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)可以(yi)看作(zuo)是變(bian)壓器(qi)(qi)和整(zheng)流(liu)(liu)器(qi)(qi)，可以(yi)起到保護電(dian)(dian)(dian)(dian)器(qi)(qi)和人身安全(quan)的(de)作(zuo)用(yong)。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配(pei)器(qi)(qi)(qi)并(bing)不是(shi)(shi)(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配(pei)器(qi)(qi)(qi)是(shi)(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)開關，用于(yu)提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力能(neng)源(yuan)(yuan)(yuan)，可以給(gei)投影儀、筆(bi)記本(ben)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦、音響、凈水器(qi)(qi)(qi)等家用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子產(chan)品提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力；而(er)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)是(shi)(shi)(shi)(shi)用來給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的，一般會(hui)根(gen)據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容(rong)量和充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)特(te)性(xing)進行分階段充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，二者是(shi)(shi)(shi)(shi)不同的。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配(pei)器(qi)(qi)(qi)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的區(qu)別還體現(xian)在(zai)定義(yi)、結構、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流模式、用途等方(fang)面，最大的區(qu)別就是(shi)(shi)(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)只是(shi)(shi)(shi)(shi)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而(er)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配(pei)器(qi)(qi)(qi)不僅能(neng)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，還能(neng)給(gei)主機供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一般情況下(xia)，電(dian)(dian)源適(shi)配(pei)器能否(fou)通(tong)用(yong)(yong)要(yao)滿足三個條件：輸(shu)(shu)出電(dian)(dian)壓必須相(xiang)同、輸(shu)(shu)出的額(e)定電(dian)(dian)流比(bi)原(yuan)電(dian)(dian)器要(yao)求的要(yao)大、接口相(xiang)同，如果這三個方面都滿足的話(hua)，可(ke)(ke)(ke)以臨(lin)時通(tong)用(yong)(yong)一下(xia)。不過需要(yao)注意(yi)的是，部分(fen)電(dian)(dian)源適(shi)配(pei)器也是不可(ke)(ke)(ke)以通(tong)用(yong)(yong)的，通(tong)用(yong)(yong)可(ke)(ke)(ke)能會導致(zhi)電(dian)(dian)器燒壞、無法使用(yong)(yong)等問題，因(yin)此如果原(yuan)來的電(dian)(dian)源適(shi)配(pei)器損(sun)壞，建議(yi)還是聯系廠(chang)家購買一個原(yuan)裝電(dian)(dian)源適(shi)配(pei)器比(bi)較好。

四、電源適配器多少錢一個

電源適配器的價格并不高，根據輸入電壓大小、輸入電流類型、供電方式、電源安數等有所不同，價格大概在二十多元到四五十元左右，也有部分電源適配器產品可能會更貴一些。需要注意的是，電源適配器市場比較混亂，有一些比較便宜的電源適配器甚至只要幾塊錢，這種可能是以次充好、以舊充新的產品，不建議購買，要選擇正規優質的電源適配器品牌廠家購買產品。
