1.充電(dian)器是(shi)一種將(jiang)交流(liu)電(dian)轉換(huan)為(wei)低(di)壓(ya)直流(liu)電(dian)的供(gong)電(dian)設備，采用電(dian)力電(dian)子半導體器件，將(jiang)電(dian)壓(ya)和頻(pin)率(lv)固(gu)定(ding)不變的交流(liu)電(dian)變換(huan)為(wei)直流(liu)電(dian)的一種靜止變流(liu)裝置。

2.適(shi)(shi)配器(qi)(qi)就是(shi)一(yi)個(ge)(ge)接(jie)口轉(zhuan)移器(qi)(qi)，一(yi)般由外(wai)殼、電(dian)(dian)(dian)源變壓器(qi)(qi)和整流(liu)電(dian)(dian)(dian)路(lu)組成，適(shi)(shi)用于小(xiao)型便攜(xie)式電(dian)(dian)(dian)子(zi)(zi)設備(bei)及電(dian)(dian)(dian)子(zi)(zi)電(dian)(dian)(dian)器(qi)(qi)的供電(dian)(dian)(dian)電(dian)(dian)(dian)源變換設備(bei)。適(shi)(shi)配器(qi)(qi)可以是(shi)一(yi)個(ge)(ge)獨立的硬件接(jie)口設備(bei)，也可以是(shi)信息接(jie)口。通常(chang)使用的適(shi)(shi)配器(qi)(qi)一(yi)般有電(dian)(dian)(dian)源適(shi)(shi)配器(qi)(qi)、USB與串口的轉(zhuan)接(jie)設備(bei)等。

總結(jie)：充電器(qi)(qi)是包括了適(shi)(shi)配(pei)器(qi)(qi)功能的，它比適(shi)(shi)配(pei)器(qi)(qi)多(duo)一個(ge)控制電路(lu)。適(shi)(shi)配(pei)器(qi)(qi)只起到(dao)穩壓作用(yong)，充電器(qi)(qi)具有(you)恒流和限壓設計。
