一、電源適配器是什么

電(dian)(dian)(dian)源(yuan)適配器(qi)(qi)(qi)又稱外置電(dian)(dian)(dian)源(yuan)，是(shi)一(yi)種小型便(bian)攜式電(dian)(dian)(dian)子設(she)備(bei)及電(dian)(dian)(dian)子電(dian)(dian)(dian)器(qi)(qi)(qi)的供電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)變換設(she)備(bei)，由外殼、變壓(ya)(ya)器(qi)(qi)(qi)、電(dian)(dian)(dian)感、電(dian)(dian)(dian)容、控制IC、PCB板等元器(qi)(qi)(qi)件組成，它的作(zuo)用主要是(shi)：將電(dian)(dian)(dian)流由交流輸(shu)入(ru)轉換為(wei)直流輸(shu)出，把不穩定(ding)的電(dian)(dian)(dian)源(yuan)通過轉化(hua)電(dian)(dian)(dian)路變成電(dian)(dian)(dian)子產(chan)品需(xu)要的恒(heng)壓(ya)(ya)直流電(dian)(dian)(dian)，從(cong)而給物體供電(dian)(dian)(dian)和充電(dian)(dian)(dian)。電(dian)(dian)(dian)源(yuan)適配器(qi)(qi)(qi)可以看作(zuo)是(shi)變壓(ya)(ya)器(qi)(qi)(qi)和整流器(qi)(qi)(qi)，可以起(qi)到保護電(dian)(dian)(dian)器(qi)(qi)(qi)和人(ren)身(shen)安全的作(zuo)用。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)并不(bu)是(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)源(yuan)開關，用(yong)(yong)于提供電(dian)(dian)(dian)(dian)(dian)力能(neng)源(yuan)，可以給投影(ying)儀、筆記(ji)本電(dian)(dian)(dian)(dian)(dian)腦、音響、凈水器(qi)(qi)等家(jia)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)子產(chan)品(pin)提供電(dian)(dian)(dian)(dian)(dian)力；而(er)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)(shi)用(yong)(yong)來給電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)的，一般會根(gen)據(ju)電(dian)(dian)(dian)(dian)(dian)池(chi)容量和(he)充(chong)電(dian)(dian)(dian)(dian)(dian)特性(xing)進行分階段(duan)充(chong)電(dian)(dian)(dian)(dian)(dian)，二者是(shi)(shi)不(bu)同的。電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)和(he)電(dian)(dian)(dian)(dian)(dian)源(yuan)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的區(qu)別還體現(xian)在定義、結(jie)構(gou)、電(dian)(dian)(dian)(dian)(dian)流模式、用(yong)(yong)途等方(fang)面，最(zui)大的區(qu)別就是(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)只是(shi)(shi)給電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)，而(er)電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)不(bu)僅能(neng)給電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)，還能(neng)給主機供電(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一般(ban)情況下，電(dian)源(yuan)(yuan)適(shi)配器能否通用(yong)要(yao)(yao)滿足三個(ge)(ge)條(tiao)件：輸(shu)出電(dian)壓必須相同(tong)(tong)、輸(shu)出的額定電(dian)流比(bi)原(yuan)電(dian)器要(yao)(yao)求(qiu)的要(yao)(yao)大、接口相同(tong)(tong)，如果(guo)這三個(ge)(ge)方(fang)面都滿足的話，可(ke)(ke)以臨時(shi)通用(yong)一下。不過需要(yao)(yao)注意的是，部(bu)分電(dian)源(yuan)(yuan)適(shi)配器也(ye)是不可(ke)(ke)以通用(yong)的，通用(yong)可(ke)(ke)能會導致(zhi)電(dian)器燒(shao)壞(huai)、無法使(shi)用(yong)等問題，因(yin)此如果(guo)原(yuan)來的電(dian)源(yuan)(yuan)適(shi)配器損(sun)壞(huai)，建議還(huan)是聯系廠家購(gou)買(mai)一個(ge)(ge)原(yuan)裝電(dian)源(yuan)(yuan)適(shi)配器比(bi)較好(hao)。

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。
