一、電源適配器是什么

電(dian)(dian)(dian)(dian)(dian)(dian)源適(shi)(shi)配器又稱外置(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)源，是(shi)一種小型便攜式電(dian)(dian)(dian)(dian)(dian)(dian)子設備及電(dian)(dian)(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)(dian)(dian)器的(de)供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)變換(huan)設備，由外殼(ke)、變壓(ya)(ya)器、電(dian)(dian)(dian)(dian)(dian)(dian)感、電(dian)(dian)(dian)(dian)(dian)(dian)容、控制IC、PCB板(ban)等元器件組成，它的(de)作(zuo)(zuo)用(yong)(yong)主(zhu)要是(shi)：將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)流由交流輸(shu)入(ru)轉換(huan)為(wei)直流輸(shu)出，把(ba)不穩定(ding)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源通過轉化(hua)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)變成電(dian)(dian)(dian)(dian)(dian)(dian)子產品(pin)需(xu)要的(de)恒(heng)壓(ya)(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)，從而給物體供電(dian)(dian)(dian)(dian)(dian)(dian)和充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)(dian)(dian)源適(shi)(shi)配器可以看(kan)作(zuo)(zuo)是(shi)變壓(ya)(ya)器和整流器，可以起到保護電(dian)(dian)(dian)(dian)(dian)(dian)器和人身安(an)全的(de)作(zuo)(zuo)用(yong)(yong)。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)(qi)(qi)(qi)并不(bu)是(shi)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)(qi)(qi)(qi)是(shi)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)開(kai)關，用(yong)(yong)于(yu)提供(gong)電(dian)(dian)(dian)(dian)(dian)力能(neng)源(yuan)(yuan)，可以給(gei)投影儀、筆(bi)記本電(dian)(dian)(dian)(dian)(dian)腦(nao)、音響、凈水器(qi)(qi)(qi)(qi)等家用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)子產品提供(gong)電(dian)(dian)(dian)(dian)(dian)力；而充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)是(shi)用(yong)(yong)來(lai)給(gei)電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)的，一般(ban)會根(gen)據電(dian)(dian)(dian)(dian)(dian)池(chi)容(rong)量和(he)充(chong)電(dian)(dian)(dian)(dian)(dian)特性進行分階(jie)段(duan)充(chong)電(dian)(dian)(dian)(dian)(dian)，二者(zhe)是(shi)不(bu)同的。電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)(qi)(qi)(qi)和(he)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)的區別還(huan)(huan)體現在定義、結構、電(dian)(dian)(dian)(dian)(dian)流模式(shi)、用(yong)(yong)途等方面，最(zui)大的區別就是(shi)充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)只是(shi)給(gei)電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)，而電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)(qi)(qi)(qi)不(bu)僅能(neng)給(gei)電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)，還(huan)(huan)能(neng)給(gei)主(zhu)機(ji)供(gong)電(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一般情(qing)況下，電源(yuan)適(shi)配(pei)器(qi)(qi)能否通(tong)(tong)用(yong)(yong)要滿(man)足(zu)(zu)三個(ge)條(tiao)件：輸出電壓必(bi)須相同(tong)、輸出的(de)(de)(de)額(e)定(ding)電流(liu)比(bi)原電器(qi)(qi)要求的(de)(de)(de)要大(da)、接口相同(tong)，如(ru)果這三個(ge)方面都滿(man)足(zu)(zu)的(de)(de)(de)話，可以(yi)臨時通(tong)(tong)用(yong)(yong)一下。不(bu)過需要注意的(de)(de)(de)是(shi)，部(bu)分電源(yuan)適(shi)配(pei)器(qi)(qi)也是(shi)不(bu)可以(yi)通(tong)(tong)用(yong)(yong)的(de)(de)(de)，通(tong)(tong)用(yong)(yong)可能會導(dao)致電器(qi)(qi)燒壞、無法使用(yong)(yong)等問題，因(yin)此(ci)如(ru)果原來的(de)(de)(de)電源(yuan)適(shi)配(pei)器(qi)(qi)損壞，建議(yi)還是(shi)聯系廠(chang)家(jia)購買一個(ge)原裝電源(yuan)適(shi)配(pei)器(qi)(qi)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。
