一、電源適配器是充電器嗎

不是。

很多朋友都會搞混(hun)電(dian)(dian)源適配器(qi)和(he)充(chong)(chong)電(dian)(dian)器(qi)的(de)關(guan)系，但(dan)其實嚴格意義上這是兩種不同的(de)概(gai)念(nian)：電(dian)(dian)源適配器(qi)是電(dian)(dian)源開關(guan)，用(yong)于提供電(dian)(dian)力(li)能源，可以給(gei)投(tou)影儀、筆(bi)記本電(dian)(dian)腦(nao)、音響(xiang)、凈(jing)水器(qi)等家用(yong)電(dian)(dian)器(qi)或電(dian)(dian)子產品提供電(dian)(dian)力(li)；而充(chong)(chong)電(dian)(dian)器(qi)是用(yong)來給(gei)電(dian)(dian)池充(chong)(chong)電(dian)(dian)的(de)，一般會根據電(dian)(dian)池容量(liang)和(he)充(chong)(chong)電(dian)(dian)特性進行分階段充(chong)(chong)電(dian)(dian)，二(er)者是不同的(de)。

二、電源適配器和充電器有什么區別

電源(yuan)適(shi)配器和充電器的區(qu)別(bie)主要有：

1、定義(yi)不(bu)同：電(dian)(dian)源(yuan)適配器是一種電(dian)(dian)子設備(bei)和(he)電(dian)(dian)子電(dian)(dian)器供電(dian)(dian)電(dian)(dian)源(yuan)變換的設備(bei)。充電(dian)(dian)器是一種用了高頻(pin)電(dian)(dian)源(yuan)技術(shu)和(he)先(xian)進(jin)的智(zhi)能動態調整充電(dian)(dian)技術(shu)。

2、結構組(zu)成(cheng)不(bu)同：電(dian)(dian)源適配器由(you)(you)外殼、變壓器是、pcb板(ban)等組(zu)成(cheng)。充電(dian)(dian)器由(you)(you)外殼、輸(shu)入端(duan)、輸(shu)出(chu)端(duan)等組(zu)成(cheng)。

3、電(dian)(dian)(dian)流(liu)模式不同：電(dian)(dian)(dian)源適配器(qi)的(de)電(dian)(dian)(dian)流(liu)模式是(shi)從交流(liu)輸入到(dao)直(zhi)流(liu)輸出(chu)。充電(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)流(liu)模式使用恒流(liu)限壓充電(dian)(dian)(dian)系統。

4、用途不同：充(chong)電(dian)(dian)器只是(shi)給(gei)電(dian)(dian)池充(chong)電(dian)(dian)，而電(dian)(dian)源適配器不僅能(neng)給(gei)電(dian)(dian)池充(chong)電(dian)(dian)，還能(neng)給(gei)主機供電(dian)(dian)。

三、電源適配器可以當充電器用嗎

不能(neng)。用電源(yuan)適(shi)配器或(huo)穩壓電源(yuan)給電池充電，可能(neng)造(zao)成的(de)情況有：

1、如果(guo)電(dian)(dian)壓(ya)輸出不夠(gou)大，會(hui)出現充不滿或充電(dian)(dian)緩慢(man)的情況。

2、如果輸出電(dian)(dian)(dian)(dian)壓(ya)足夠，那么在充電(dian)(dian)(dian)(dian)初期(qi)被充電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓(ya)較低時會有巨大(da)的(de)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流，嚴重還會損傷(shang)電(dian)(dian)(dian)(dian)池(chi)壽命(ming)。

因此充電應該用正規的充電器，不要用電源適配器充電(dian)(dian)(dian)，如果臨時湊(cou)合，至(zhi)少(shao)要串(chuan)入一定的(de)限流電(dian)(dian)(dian)阻(zu)，用增(zeng)加內阻(zu)的(de)辦法(fa)來(lai)控制(zhi)充電(dian)(dian)(dian)電(dian)(dian)(dian)流不致過高。當然專(zhuan)門為充電(dian)(dian)(dian)制(zhi)作(zuo)的(de)適(shi)配(pei)器例外，像手機電(dian)(dian)(dian)源適(shi)配(pei)器盡管沒(mei)有恒流功能，但(dan)是(shi)這些功能制(zhi)作(zuo)集成在手機內部，因此也是(shi)可(ke)以使用的(de)。
