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)源適配(pei)器(qi)和(he)充(chong)(chong)電(dian)(dian)(dian)器(qi)的關系(xi)，但其實嚴格(ge)意義上這是(shi)兩種不同的概(gai)念：電(dian)(dian)(dian)源適配(pei)器(qi)是(shi)電(dian)(dian)(dian)源開關，用(yong)(yong)于提(ti)供電(dian)(dian)(dian)力能源，可以給投影儀(yi)、筆記本電(dian)(dian)(dian)腦、音(yin)響、凈水器(qi)等家用(yong)(yong)電(dian)(dian)(dian)器(qi)或電(dian)(dian)(dian)子產(chan)品(pin)提(ti)供電(dian)(dian)(dian)力；而(er)充(chong)(chong)電(dian)(dian)(dian)器(qi)是(shi)用(yong)(yong)來給電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)的，一般(ban)會根(gen)據電(dian)(dian)(dian)池容量和(he)充(chong)(chong)電(dian)(dian)(dian)特(te)性進行分階段充(chong)(chong)電(dian)(dian)(dian)，二(er)者是(shi)不同的。

二、電源適配器和充電器有什么區別

電源適(shi)配器和充電器的區(qu)別(bie)主(zhu)要(yao)有(you)：

1、定(ding)義不同：電(dian)(dian)(dian)(dian)源(yuan)適配器是一(yi)種電(dian)(dian)(dian)(dian)子設(she)備和電(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)器供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)變換的設(she)備。充電(dian)(dian)(dian)(dian)器是一(yi)種用了高頻電(dian)(dian)(dian)(dian)源(yuan)技(ji)術和先進的智能動態調整(zheng)充電(dian)(dian)(dian)(dian)技(ji)術。

2、結(jie)構組(zu)成(cheng)(cheng)不同：電(dian)源(yuan)適配器(qi)由外殼、變壓器(qi)是(shi)、pcb板等(deng)組(zu)成(cheng)(cheng)。充(chong)電(dian)器(qi)由外殼、輸(shu)入端、輸(shu)出端等(deng)組(zu)成(cheng)(cheng)。

3、電(dian)(dian)流(liu)模式(shi)不(bu)同：電(dian)(dian)源(yuan)適配(pei)器(qi)的電(dian)(dian)流(liu)模式(shi)是(shi)從交流(liu)輸(shu)入到(dao)直流(liu)輸(shu)出。充(chong)電(dian)(dian)器(qi)的電(dian)(dian)流(liu)模式(shi)使用(yong)恒流(liu)限壓充(chong)電(dian)(dian)系(xi)統。

4、用(yong)途不同：充電(dian)器只是給電(dian)池(chi)充電(dian)，而電(dian)源適配器不僅能(neng)給電(dian)池(chi)充電(dian)，還能(neng)給主機供(gong)電(dian)。

三、電源適配器可以當充電器用嗎

不能(neng)。用電(dian)源適配器或(huo)穩壓電(dian)源給電(dian)池充電(dian)，可能(neng)造(zao)成(cheng)的情(qing)況有：

1、如果電壓(ya)輸(shu)出(chu)不夠大(da)，會出(chu)現充(chong)不滿(man)或(huo)充(chong)電緩慢的情況。

2、如果輸出電壓足夠(gou)，那么(me)在充電初期被充電池電壓較低時會(hui)有巨(ju)大的(de)充電電流，嚴重(zhong)還會(hui)損傷(shang)電池壽(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)，如(ru)果臨時(shi)湊合，至少(shao)要(yao)串入(ru)一定的(de)(de)限流電(dian)阻(zu)，用(yong)增加內阻(zu)的(de)(de)辦法來控制(zhi)充(chong)電(dian)電(dian)流不致(zhi)過高。當然專門為充(chong)電(dian)制(zhi)作的(de)(de)適配器例外(wai)，像手機(ji)電(dian)源適配器盡(jin)管沒有(you)恒(heng)流功能，但(dan)是這些功能制(zhi)作集成在手機(ji)內部，因此也是可(ke)以(yi)使用(yong)的(de)(de)。
