一、電源適配器是什么
電(dian)(dian)(dian)(dian)源(yuan)適配器(qi)又稱外(wai)(wai)置(zhi)電(dian)(dian)(dian)(dian)源(yuan),是一種(zhong)小型便攜式電(dian)(dian)(dian)(dian)子設備(bei)及電(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)器(qi)的供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓變(bian)換設備(bei),由外(wai)(wai)殼、變(bian)壓器(qi)、電(dian)(dian)(dian)(dian)感、電(dian)(dian)(dian)(dian)容、控制IC、PCB板等元器(qi)件(jian)組(zu)成(cheng),它的作(zuo)用主要是:將電(dian)(dian)(dian)(dian)流(liu)由交流(liu)輸(shu)(shu)入轉(zhuan)換為直流(liu)輸(shu)(shu)出,把不穩定的電(dian)(dian)(dian)(dian)源(yuan)通過轉(zhuan)化電(dian)(dian)(dian)(dian)路變(bian)成(cheng)電(dian)(dian)(dian)(dian)子產品需要的恒(heng)壓直流(liu)電(dian)(dian)(dian)(dian),從而(er)給物體(ti)供電(dian)(dian)(dian)(dian)和(he)(he)充電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)源(yuan)適配器(qi)可以(yi)看(kan)作(zuo)是變(bian)壓器(qi)和(he)(he)整(zheng)流(liu)器(qi),可以(yi)起到(dao)保護電(dian)(dian)(dian)(dian)器(qi)和(he)(he)人身(shen)安全的作(zuo)用。
二、電源適配器是充電器嗎
電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)并不(bu)(bu)是(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi),電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)開關,用于提供電(dian)(dian)(dian)(dian)(dian)(dian)力能源(yuan),可以給(gei)(gei)投影儀、筆記本(ben)電(dian)(dian)(dian)(dian)(dian)(dian)腦、音響、凈水器(qi)(qi)等家用電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)產品提供電(dian)(dian)(dian)(dian)(dian)(dian)力;而(er)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)(shi)用來(lai)給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de),一(yi)般會根據電(dian)(dian)(dian)(dian)(dian)(dian)池容量和充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)特性(xing)進行分階段充(chong)電(dian)(dian)(dian)(dian)(dian)(dian),二者是(shi)(shi)不(bu)(bu)同的(de)。電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)和電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)區別還體現(xian)在定義、結構、電(dian)(dian)(dian)(dian)(dian)(dian)流模式(shi)、用途(tu)等方(fang)面,最(zui)大的(de)區別就是(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)只是(shi)(shi)給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian),而(er)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)不(bu)(bu)僅能給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian),還能給(gei)(gei)主機供電(dian)(dian)(dian)(dian)(dian)(dian)。
三、電源適配器可以通用嗎
一般情況下,電源(yuan)適(shi)配(pei)器能(neng)否通(tong)用要(yao)滿(man)足(zu)三(san)個(ge)條件:輸(shu)出電壓必須相(xiang)同、輸(shu)出的(de)額定(ding)電流比原(yuan)電器要(yao)求的(de)要(yao)大(da)、接口相(xiang)同,如果(guo)(guo)這三(san)個(ge)方面都滿(man)足(zu)的(de)話,可(ke)以(yi)臨時通(tong)用一下。不過需要(yao)注意的(de)是(shi),部分電源(yuan)適(shi)配(pei)器也(ye)是(shi)不可(ke)以(yi)通(tong)用的(de),通(tong)用可(ke)能(neng)會導致電器燒(shao)壞、無法(fa)使用等問題,因此(ci)如果(guo)(guo)原(yuan)來(lai)的(de)電源(yuan)適(shi)配(pei)器損壞,建議(yi)還是(shi)聯(lian)系廠(chang)家購買一個(ge)原(yuan)裝電源(yuan)適(shi)配(pei)器比較好。
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。
選(xuan)購(gou)電(dian)源(yuan)適(shi)配器時千萬(wan)不要因為價格便(bian)宜,而盲目跟從購(gou)買(mai),選(xuan)擇(ze)比較有知名(ming)度的(de)(de)品牌(pai),不僅(jin)品質(zhi)有保證,售后服務也有保障。當(dang)然追(zhui)求(qiu)品牌(pai)的(de)(de)東(dong)西不一(yi)定就是追(zhui)求(qiu)價格的(de)(de)昂貴(gui),不同的(de)(de)經濟水(shui)平我們(men)可以選(xuan)擇(ze)不同價位的(de)(de)名(ming)牌(pai)產(chan)品。選(xuan)擇(ze)網購(gou)商品的(de)(de)朋友要認準品牌(pai)的(de)(de)旗艦(jian)店鋪,這樣子才能做到萬(wan)無一(yi)失。
