1.充(chong)電(dian)(dian)器是一(yi)種將(jiang)交流(liu)電(dian)(dian)轉(zhuan)換為低壓直流(liu)電(dian)(dian)的(de)供電(dian)(dian)設備，采用電(dian)(dian)力電(dian)(dian)子半導體(ti)器件，將(jiang)電(dian)(dian)壓和(he)頻率固定不變(bian)的(de)交流(liu)電(dian)(dian)變(bian)換為直流(liu)電(dian)(dian)的(de)一(yi)種靜止變(bian)流(liu)裝置。

2.適配(pei)器(qi)就是(shi)一個接口轉(zhuan)移(yi)器(qi)，一般由外殼、電(dian)(dian)源變(bian)(bian)壓器(qi)和整(zheng)流電(dian)(dian)路組成，適用(yong)于小(xiao)型便(bian)攜式(shi)電(dian)(dian)子設(she)備(bei)及電(dian)(dian)子電(dian)(dian)器(qi)的(de)供(gong)電(dian)(dian)電(dian)(dian)源變(bian)(bian)換設(she)備(bei)。適配(pei)器(qi)可(ke)以是(shi)一個獨立(li)的(de)硬件接口設(she)備(bei)，也可(ke)以是(shi)信(xin)息接口。通常使用(yong)的(de)適配(pei)器(qi)一般有電(dian)(dian)源適配(pei)器(qi)、USB與串(chuan)口的(de)轉(zhuan)接設(she)備(bei)等(deng)。

總結(jie)：充(chong)(chong)電器(qi)(qi)是包括了適配(pei)器(qi)(qi)功能的(de)，它(ta)比適配(pei)器(qi)(qi)多一個控制電路(lu)。適配(pei)器(qi)(qi)只(zhi)起到穩壓作用，充(chong)(chong)電器(qi)(qi)具有恒流(liu)和(he)限壓設(she)計。
