一、電源適配器是什么

電(dian)(dian)(dian)(dian)(dian)源適配器又(you)稱(cheng)外置電(dian)(dian)(dian)(dian)(dian)源，是(shi)一種小型便攜式(shi)電(dian)(dian)(dian)(dian)(dian)子設備及(ji)電(dian)(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)(dian)器的(de)(de)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)變換設備，由外殼、變壓(ya)(ya)器、電(dian)(dian)(dian)(dian)(dian)感(gan)、電(dian)(dian)(dian)(dian)(dian)容、控(kong)制IC、PCB板等元器件組成(cheng)，它的(de)(de)作用(yong)主(zhu)要是(shi)：將電(dian)(dian)(dian)(dian)(dian)流(liu)由交流(liu)輸入轉(zhuan)換為(wei)直流(liu)輸出(chu)，把不穩(wen)定的(de)(de)電(dian)(dian)(dian)(dian)(dian)源通過轉(zhuan)化電(dian)(dian)(dian)(dian)(dian)路變成(cheng)電(dian)(dian)(dian)(dian)(dian)子產品需要的(de)(de)恒壓(ya)(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，從而(er)給物(wu)體供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)和充電(dian)(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)(dian)源適配器可以看(kan)作是(shi)變壓(ya)(ya)器和整流(liu)器，可以起到保護電(dian)(dian)(dian)(dian)(dian)器和人身安(an)全的(de)(de)作用(yong)。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源適(shi)(shi)配(pei)器(qi)并不是(shi)(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源適(shi)(shi)配(pei)器(qi)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源開關(guan)，用于提(ti)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力能(neng)源，可(ke)以(yi)給(gei)投影(ying)儀(yi)、筆記本電(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦、音響、凈(jing)水器(qi)等家(jia)用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)或電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子產品提(ti)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力；而充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是(shi)(shi)用來給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的，一般會(hui)根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池容量和(he)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)特性進行分(fen)階段充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，二(er)者(zhe)是(shi)(shi)不同的。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源適(shi)(shi)配(pei)器(qi)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的區別還體現在定義、結構、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流模式、用途等方面，最大的區別就是(shi)(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)只是(shi)(shi)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源適(shi)(shi)配(pei)器(qi)不僅(jin)能(neng)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，還能(neng)給(gei)主機供(gong)電(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)(dian)(dian)源適(shi)配(pei)(pei)器能(neng)否通用(yong)要滿足(zu)三(san)個條件：輸(shu)出電(dian)(dian)(dian)(dian)壓必須(xu)相同、輸(shu)出的額定電(dian)(dian)(dian)(dian)流比(bi)原電(dian)(dian)(dian)(dian)器要求的要大、接口相同，如(ru)果這三(san)個方面都(dou)滿足(zu)的話，可(ke)以(yi)臨時通用(yong)一下(xia)。不過需要注(zhu)意的是(shi)，部分電(dian)(dian)(dian)(dian)源適(shi)配(pei)(pei)器也是(shi)不可(ke)以(yi)通用(yong)的，通用(yong)可(ke)能(neng)會(hui)導(dao)致電(dian)(dian)(dian)(dian)器燒壞、無(wu)法使(shi)用(yong)等問題，因此如(ru)果原來的電(dian)(dian)(dian)(dian)源適(shi)配(pei)(pei)器損壞，建(jian)議還是(shi)聯系廠家購買一個原裝(zhuang)電(dian)(dian)(dian)(dian)源適(shi)配(pei)(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。
