一、電源適配器是充電器嗎

不是。

很多朋(peng)友都會搞混電(dian)(dian)(dian)(dian)源適配(pei)器(qi)和(he)充(chong)電(dian)(dian)(dian)(dian)器(qi)的(de)關系，但其實嚴格意義上這(zhe)是兩種不(bu)同的(de)概念(nian)：電(dian)(dian)(dian)(dian)源適配(pei)器(qi)是電(dian)(dian)(dian)(dian)源開關，用(yong)于(yu)提(ti)供電(dian)(dian)(dian)(dian)力能源，可以給(gei)投影儀、筆(bi)記本電(dian)(dian)(dian)(dian)腦、音(yin)響、凈水器(qi)等家用(yong)電(dian)(dian)(dian)(dian)器(qi)或(huo)電(dian)(dian)(dian)(dian)子產品提(ti)供電(dian)(dian)(dian)(dian)力；而充(chong)電(dian)(dian)(dian)(dian)器(qi)是用(yong)來給(gei)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)的(de)，一般會根(gen)據電(dian)(dian)(dian)(dian)池容量和(he)充(chong)電(dian)(dian)(dian)(dian)特性(xing)進行分階段充(chong)電(dian)(dian)(dian)(dian)，二者是不(bu)同的(de)。

二、電源適配器和充電器有什么區別

電源適配器和充(chong)電器的區別主要(yao)有：

1、定義不同：電(dian)(dian)源(yuan)適配(pei)器是一種(zhong)電(dian)(dian)子(zi)設備和電(dian)(dian)子(zi)電(dian)(dian)器供(gong)電(dian)(dian)電(dian)(dian)源(yuan)變換的設備。充電(dian)(dian)器是一種(zhong)用(yong)了高頻電(dian)(dian)源(yuan)技(ji)(ji)術和先進的智能動態調整充電(dian)(dian)技(ji)(ji)術。

2、結構組(zu)成(cheng)不同：電源適配器(qi)由外殼(ke)、變(bian)壓器(qi)是、pcb板等組(zu)成(cheng)。充(chong)電器(qi)由外殼(ke)、輸入(ru)端、輸出端等組(zu)成(cheng)。

3、電(dian)流模式(shi)不同(tong)：電(dian)源(yuan)適配器的電(dian)流模式(shi)是(shi)從(cong)交流輸入到直流輸出(chu)。充電(dian)器的電(dian)流模式(shi)使用恒流限壓充電(dian)系(xi)統。

4、用途(tu)不(bu)同(tong)：充(chong)電(dian)器只(zhi)是(shi)給(gei)(gei)電(dian)池充(chong)電(dian)，而電(dian)源適配器不(bu)僅(jin)能給(gei)(gei)電(dian)池充(chong)電(dian)，還能給(gei)(gei)主機供電(dian)。

三、電源適配器可以當充電器用嗎

不能。用電源(yuan)適(shi)配(pei)器或穩(wen)壓電源(yuan)給(gei)電池充電，可能造成的情況有：

1、如(ru)果電壓輸出不(bu)夠大，會(hui)出現充不(bu)滿(man)或充電緩慢的情況。

2、如果(guo)輸出電(dian)(dian)壓足夠，那么在充(chong)(chong)電(dian)(dian)初期被充(chong)(chong)電(dian)(dian)池電(dian)(dian)壓較(jiao)低(di)時會有巨(ju)大(da)的充(chong)(chong)電(dian)(dian)電(dian)(dian)流，嚴(yan)重(zhong)還會損傷電(dian)(dian)池壽命(ming)。

因此充電應該用正規的充電器，不要用電源適配器充(chong)電(dian)(dian)(dian)，如果臨時湊合，至少要串入一(yi)定的(de)限流電(dian)(dian)(dian)阻，用增(zeng)加(jia)內阻的(de)辦(ban)法來控制充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流不致(zhi)過高。當(dang)然專門為充(chong)電(dian)(dian)(dian)制作的(de)適配(pei)器例(li)外(wai)，像手機(ji)電(dian)(dian)(dian)源適配(pei)器盡(jin)管沒有恒流功能，但是這些(xie)功能制作集成在手機(ji)內部，因此也是可以使用的(de)。
