一、電源適配器是什么

電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)又稱外置電(dian)(dian)(dian)(dian)源(yuan)，是(shi)(shi)一種小型便攜式電(dian)(dian)(dian)(dian)子設備及電(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)器(qi)(qi)的供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)變(bian)換(huan)設備，由(you)外殼(ke)、變(bian)壓(ya)(ya)(ya)器(qi)(qi)、電(dian)(dian)(dian)(dian)感、電(dian)(dian)(dian)(dian)容、控制(zhi)IC、PCB板等(deng)元(yuan)器(qi)(qi)件(jian)組(zu)成(cheng)，它的作(zuo)(zuo)用(yong)主要(yao)是(shi)(shi)：將電(dian)(dian)(dian)(dian)流由(you)交(jiao)流輸(shu)入轉(zhuan)換(huan)為直流輸(shu)出，把(ba)不穩定的電(dian)(dian)(dian)(dian)源(yuan)通(tong)過轉(zhuan)化電(dian)(dian)(dian)(dian)路變(bian)成(cheng)電(dian)(dian)(dian)(dian)子產品(pin)需要(yao)的恒壓(ya)(ya)(ya)直流電(dian)(dian)(dian)(dian)，從而(er)給物體供電(dian)(dian)(dian)(dian)和(he)充電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)可以(yi)看作(zuo)(zuo)是(shi)(shi)變(bian)壓(ya)(ya)(ya)器(qi)(qi)和(he)整流器(qi)(qi)，可以(yi)起到(dao)保護電(dian)(dian)(dian)(dian)器(qi)(qi)和(he)人身安(an)全的作(zuo)(zuo)用(yong)。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)(qi)并不是(shi)(shi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)(qi)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)開(kai)關，用(yong)(yong)于提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力能(neng)源(yuan)(yuan)，可以給投影儀、筆記本電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)、音響、凈水(shui)器(qi)(qi)(qi)等(deng)家用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子產品提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力；而充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)是(shi)(shi)用(yong)(yong)來給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)，一般(ban)會根(gen)據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池容量和充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)特性進行分(fen)階(jie)段充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，二者是(shi)(shi)不同(tong)的(de)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)(qi)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的(de)區(qu)別還(huan)體現在定義、結構、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流模式、用(yong)(yong)途等(deng)方面，最大的(de)區(qu)別就是(shi)(shi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)只是(shi)(shi)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)(qi)不僅能(neng)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，還(huan)能(neng)給主機供電(dian)(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(yuan)(yuan)適(shi)配(pei)器(qi)能否(fou)通用要(yao)(yao)滿足(zu)三個(ge)條件：輸(shu)(shu)出(chu)電(dian)(dian)壓必須相同、輸(shu)(shu)出(chu)的(de)額定電(dian)(dian)流比原電(dian)(dian)器(qi)要(yao)(yao)求的(de)要(yao)(yao)大、接口(kou)相同，如(ru)果(guo)這三個(ge)方面都滿足(zu)的(de)話，可以臨時通用一下(xia)。不過(guo)需要(yao)(yao)注意(yi)的(de)是(shi)，部分電(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)也(ye)是(shi)不可以通用的(de)，通用可能會導(dao)致電(dian)(dian)器(qi)燒壞(huai)、無法使(shi)用等問題，因此如(ru)果(guo)原來的(de)電(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)損壞(huai)，建議還是(shi)聯系廠家購(gou)買(mai)一個(ge)原裝(zhuang)電(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)比較(jiao)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。
