一、電源適配器是充電器嗎
不是。
很多(duo)朋友都(dou)會搞混電(dian)(dian)(dian)源(yuan)適配器和充(chong)電(dian)(dian)(dian)器的(de)關系,但其實(shi)嚴格(ge)意義上(shang)這(zhe)是(shi)兩種不(bu)同(tong)的(de)概念:電(dian)(dian)(dian)源(yuan)適配器是(shi)電(dian)(dian)(dian)源(yuan)開關,用于(yu)提供電(dian)(dian)(dian)力(li)能(neng)源(yuan),可以(yi)給投影儀、筆(bi)記本電(dian)(dian)(dian)腦、音(yin)響、凈水器等家用電(dian)(dian)(dian)器或電(dian)(dian)(dian)子產品提供電(dian)(dian)(dian)力(li);而充(chong)電(dian)(dian)(dian)器是(shi)用來給電(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(rong)量和充(chong)電(dian)(dian)(dian)特性進行(xing)分階段充(chong)電(dian)(dian)(dian),二者是(shi)不(bu)同(tong)的(de)。
二、電源適配器和充電器有什么區別
電源(yuan)適配器和(he)充電器的區別(bie)主要(yao)有:
1、定義不同(tong):電源(yuan)適配器是(shi)一種電子設備(bei)和電子電器供電電源(yuan)變換的設備(bei)。充電器是(shi)一種用了高頻電源(yuan)技術和先進(jin)的智能動態調整(zheng)充電技術。
2、結構組成(cheng)(cheng)不同:電源適(shi)配器由外殼(ke)、變壓器是(shi)、pcb板等(deng)組成(cheng)(cheng)。充電器由外殼(ke)、輸入端、輸出端等(deng)組成(cheng)(cheng)。
3、電(dian)流(liu)模式不同:電(dian)源適配器的(de)電(dian)流(liu)模式是從交流(liu)輸入到(dao)直(zhi)流(liu)輸出。充電(dian)器的(de)電(dian)流(liu)模式使用恒(heng)流(liu)限壓充電(dian)系(xi)統。
4、用途(tu)不同:充電(dian)(dian)器只是給(gei)電(dian)(dian)池(chi)充電(dian)(dian),而電(dian)(dian)源適(shi)配器不僅能(neng)給(gei)電(dian)(dian)池(chi)充電(dian)(dian),還能(neng)給(gei)主機(ji)供電(dian)(dian)。
三、電源適配器可以當充電器用嗎
不能。用電(dian)源(yuan)適配器或穩壓電(dian)源(yuan)給電(dian)池充(chong)電(dian),可能造(zao)成的情況有:
1、如果電壓(ya)輸(shu)出(chu)不(bu)夠大,會出(chu)現充(chong)不(bu)滿(man)或充(chong)電緩(huan)慢的情況(kuang)。
2、如(ru)果輸出電(dian)壓(ya)足(zu)夠,那么在充電(dian)初期被充電(dian)池電(dian)壓(ya)較低(di)時會有巨大的(de)充電(dian)電(dian)流,嚴(yan)重還會損傷電(dian)池壽命。
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)(dian),如(ru)果臨(lin)時湊合,至(zhi)少要串入一(yi)定的(de)限流電(dian)(dian)(dian)阻(zu),用增加(jia)內阻(zu)的(de)辦(ban)法來(lai)控(kong)制(zhi)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流不致過高。當然專門為充(chong)電(dian)(dian)(dian)制(zhi)作的(de)適配(pei)器(qi)例外,像(xiang)手機(ji)電(dian)(dian)(dian)源適配(pei)器(qi)盡管沒有恒(heng)流功能(neng),但是(shi)這(zhe)些功能(neng)制(zhi)作集成在手機(ji)內部,因此也是(shi)可以使(shi)用的(de)。
