一、電源適配器是充電器嗎

不是。

很多朋友都會搞混電(dian)(dian)(dian)(dian)源適(shi)配(pei)器(qi)和充電(dian)(dian)(dian)(dian)器(qi)的(de)關(guan)系，但其實嚴格意義上這是(shi)兩(liang)種不同的(de)概念：電(dian)(dian)(dian)(dian)源適(shi)配(pei)器(qi)是(shi)電(dian)(dian)(dian)(dian)源開關(guan)，用(yong)于提供(gong)(gong)電(dian)(dian)(dian)(dian)力能源，可以給投影儀、筆(bi)記本電(dian)(dian)(dian)(dian)腦、音響(xiang)、凈水器(qi)等(deng)家用(yong)電(dian)(dian)(dian)(dian)器(qi)或(huo)電(dian)(dian)(dian)(dian)子(zi)產品(pin)提供(gong)(gong)電(dian)(dian)(dian)(dian)力；而充電(dian)(dian)(dian)(dian)器(qi)是(shi)用(yong)來(lai)給電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)的(de)，一(yi)般會根據電(dian)(dian)(dian)(dian)池容(rong)量和充電(dian)(dian)(dian)(dian)特性進行分階段(duan)充電(dian)(dian)(dian)(dian)，二者是(shi)不同的(de)。

二、電源適配器和充電器有什么區別

電(dian)源(yuan)適(shi)配器和(he)充電(dian)器的區(qu)別主要(yao)有：

1、定義(yi)不同(tong)：電源適配器是(shi)一種電子(zi)設(she)(she)備和電子(zi)電器供(gong)電電源變換的(de)(de)設(she)(she)備。充(chong)(chong)電器是(shi)一種用了高頻電源技(ji)術和先進的(de)(de)智能動態調(diao)整充(chong)(chong)電技(ji)術。

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

3、電流(liu)(liu)模(mo)(mo)式不同：電源適配器的電流(liu)(liu)模(mo)(mo)式是從交(jiao)流(liu)(liu)輸(shu)入到直流(liu)(liu)輸(shu)出。充電器的電流(liu)(liu)模(mo)(mo)式使用恒流(liu)(liu)限壓充電系統。

4、用途不同：充電(dian)(dian)(dian)(dian)器只是(shi)給電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)，而電(dian)(dian)(dian)(dian)源適(shi)配(pei)器不僅能給電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)，還能給主機供電(dian)(dian)(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(pei)器或穩壓電源(yuan)給電池充電，可能(neng)造(zao)成的情況有：

1、如果(guo)電壓(ya)輸出不(bu)夠(gou)大，會出現充(chong)不(bu)滿或充(chong)電緩慢的情況。

2、如(ru)果輸(shu)出電(dian)(dian)(dian)壓足夠，那么在(zai)充電(dian)(dian)(dian)初期被充電(dian)(dian)(dian)池電(dian)(dian)(dian)壓較低時會(hui)(hui)有巨(ju)大的充電(dian)(dian)(dian)電(dian)(dian)(dian)流，嚴(yan)重還會(hui)(hui)損傷電(dian)(dian)(dian)池壽(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)(dian)，如果臨時(shi)湊合，至少要串入一定的限流電(dian)(dian)阻，用(yong)增加內(nei)(nei)阻的辦法來(lai)控制充(chong)電(dian)(dian)電(dian)(dian)流不致過(guo)高。當然專(zhuan)門(men)為充(chong)電(dian)(dian)制作的適配(pei)器例外，像手機(ji)電(dian)(dian)源適配(pei)器盡管沒有恒流功能(neng)，但是這些功能(neng)制作集(ji)成在手機(ji)內(nei)(nei)部，因此也是可以使用(yong)的。
