一、電源適配器是充電器嗎

不是。

很多朋友都會搞(gao)混電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器和(he)充(chong)電(dian)(dian)(dian)器的(de)關(guan)系，但其(qi)實嚴格意義上這是(shi)兩(liang)種不同(tong)的(de)概念：電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器是(shi)電(dian)(dian)(dian)源(yuan)(yuan)開關(guan)，用(yong)于提(ti)供(gong)電(dian)(dian)(dian)力能源(yuan)(yuan)，可以給投影儀、筆記本電(dian)(dian)(dian)腦、音響、凈水器等家(jia)用(yong)電(dian)(dian)(dian)器或(huo)電(dian)(dian)(dian)子(zi)產品提(ti)供(gong)電(dian)(dian)(dian)力；而充(chong)電(dian)(dian)(dian)器是(shi)用(yong)來(lai)給電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)的(de)，一般會根據電(dian)(dian)(dian)池(chi)容量(liang)和(he)充(chong)電(dian)(dian)(dian)特性進行(xing)分階段充(chong)電(dian)(dian)(dian)，二者(zhe)是(shi)不同(tong)的(de)。

二、電源適配器和充電器有什么區別

電源適配器(qi)和充電器(qi)的區別主要(yao)有(you)：

1、定義(yi)不同：電(dian)源適(shi)配(pei)器是一(yi)種(zhong)(zhong)電(dian)子設備(bei)和(he)電(dian)子電(dian)器供電(dian)電(dian)源變換的(de)設備(bei)。充電(dian)器是一(yi)種(zhong)(zhong)用(yong)了高頻電(dian)源技術(shu)(shu)和(he)先進的(de)智(zhi)能動態調整充電(dian)技術(shu)(shu)。

2、結構組(zu)成(cheng)不同：電源適配器由外殼、變壓器是、pcb板等組(zu)成(cheng)。充電器由外殼、輸入端(duan)、輸出端(duan)等組(zu)成(cheng)。

3、電(dian)(dian)(dian)流(liu)(liu)模(mo)式不同：電(dian)(dian)(dian)源適配器的電(dian)(dian)(dian)流(liu)(liu)模(mo)式是從交流(liu)(liu)輸入到直流(liu)(liu)輸出。充電(dian)(dian)(dian)器的電(dian)(dian)(dian)流(liu)(liu)模(mo)式使用恒流(liu)(liu)限(xian)壓充電(dian)(dian)(dian)系統。

4、用途不同(tong)：充(chong)電(dian)器只是給(gei)電(dian)池充(chong)電(dian)，而(er)電(dian)源(yuan)適(shi)配器不僅能給(gei)電(dian)池充(chong)電(dian)，還能給(gei)主機供(gong)電(dian)。

三、電源適配器可以當充電器用嗎

不(bu)能。用電(dian)源適配器或穩壓電(dian)源給電(dian)池(chi)充電(dian)，可能造成的情況有：

1、如果(guo)電(dian)壓輸出(chu)(chu)不(bu)夠大(da)，會出(chu)(chu)現充不(bu)滿或充電(dian)緩慢的情況。

2、如果(guo)輸出電(dian)壓(ya)足夠，那么在充電(dian)初期被充電(dian)池電(dian)壓(ya)較(jiao)低時會(hui)有巨(ju)大的充電(dian)電(dian)流，嚴(yan)重還(huan)會(hui)損傷電(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)，如(ru)果臨時湊合，至少要(yao)串入(ru)一定的限(xian)流(liu)電(dian)(dian)阻，用增加內阻的辦法來控制(zhi)充(chong)電(dian)(dian)電(dian)(dian)流(liu)不致過高。當然(ran)專門為充(chong)電(dian)(dian)制(zhi)作(zuo)的適(shi)配器(qi)(qi)例外(wai)，像手機(ji)電(dian)(dian)源適(shi)配器(qi)(qi)盡管沒有恒流(liu)功(gong)能，但是這些功(gong)能制(zhi)作(zuo)集成在手機(ji)內部，因此也是可以使用的。
