一、電源適配器是充電器嗎

不是。

很多朋友(you)都會搞混電(dian)(dian)源(yuan)(yuan)適配器(qi)(qi)(qi)和(he)充電(dian)(dian)器(qi)(qi)(qi)的(de)關系，但(dan)其實嚴格(ge)意義上這是兩種不(bu)同(tong)的(de)概(gai)念(nian)：電(dian)(dian)源(yuan)(yuan)適配器(qi)(qi)(qi)是電(dian)(dian)源(yuan)(yuan)開關，用于提(ti)供(gong)電(dian)(dian)力(li)能(neng)源(yuan)(yuan)，可(ke)以給投影儀、筆記本電(dian)(dian)腦(nao)、音響、凈水器(qi)(qi)(qi)等家用電(dian)(dian)器(qi)(qi)(qi)或(huo)電(dian)(dian)子產品提(ti)供(gong)電(dian)(dian)力(li)；而充電(dian)(dian)器(qi)(qi)(qi)是用來給電(dian)(dian)池(chi)充電(dian)(dian)的(de)，一(yi)般會根據電(dian)(dian)池(chi)容量和(he)充電(dian)(dian)特(te)性(xing)進行(xing)分(fen)階段(duan)充電(dian)(dian)，二者是不(bu)同(tong)的(de)。

二、電源適配器和充電器有什么區別

電(dian)源(yuan)適配器(qi)和充電(dian)器(qi)的(de)區別主要(yao)有：

1、定義不同：電(dian)源適配器是一種(zhong)電(dian)子設備和電(dian)子電(dian)器供電(dian)電(dian)源變換(huan)的設備。充電(dian)器是一種(zhong)用了高頻電(dian)源技(ji)術和先進的智能動態調整充電(dian)技(ji)術。

2、結構組成(cheng)(cheng)不同(tong)：電源適配器(qi)由(you)外(wai)殼、變壓器(qi)是、pcb板等(deng)(deng)組成(cheng)(cheng)。充電器(qi)由(you)外(wai)殼、輸入端(duan)(duan)、輸出端(duan)(duan)等(deng)(deng)組成(cheng)(cheng)。

3、電(dian)(dian)(dian)流(liu)模(mo)式不同：電(dian)(dian)(dian)源適配器的(de)電(dian)(dian)(dian)流(liu)模(mo)式是從(cong)交(jiao)流(liu)輸入到(dao)直流(liu)輸出。充電(dian)(dian)(dian)器的(de)電(dian)(dian)(dian)流(liu)模(mo)式使(shi)用恒流(liu)限壓充電(dian)(dian)(dian)系(xi)統(tong)。

4、用途不同：充(chong)電(dian)器只(zhi)是給(gei)電(dian)池(chi)充(chong)電(dian)，而電(dian)源適配器不僅能(neng)(neng)給(gei)電(dian)池(chi)充(chong)電(dian)，還能(neng)(neng)給(gei)主機供(gong)電(dian)。

三、電源適配器可以當充電器用嗎

不能。用電源(yuan)適(shi)配器或穩壓(ya)電源(yuan)給電池(chi)充電，可能造成的情況有：

1、如(ru)果電壓(ya)輸出(chu)不(bu)夠大(da)，會出(chu)現充(chong)不(bu)滿或(huo)充(chong)電緩慢的情況。

2、如果(guo)輸出(chu)電(dian)(dian)壓足夠，那么在充(chong)電(dian)(dian)初期被充(chong)電(dian)(dian)池(chi)電(dian)(dian)壓較低(di)時會(hui)有巨大的充(chong)電(dian)(dian)電(dian)(dian)流，嚴重還會(hui)損傷電(dian)(dian)池(chi)壽(shou)命。

因此充電應該用正規的充電器，不要用電源適配器充(chong)電(dian)，如(ru)果臨時(shi)湊合，至少要(yao)串入一(yi)定的限流電(dian)阻，用(yong)增加(jia)內(nei)阻的辦法來(lai)控制(zhi)(zhi)充(chong)電(dian)電(dian)流不致過高。當然(ran)專門(men)為充(chong)電(dian)制(zhi)(zhi)作的適配器(qi)例外，像手機電(dian)源適配器(qi)盡管沒(mei)有恒流功(gong)能(neng)(neng)，但是(shi)這些功(gong)能(neng)(neng)制(zhi)(zhi)作集成在手機內(nei)部(bu)，因此(ci)也是(shi)可(ke)以使用(yong)的。
