1.充電(dian)(dian)(dian)器(qi)(qi)是(shi)一(yi)(yi)種將交流(liu)(liu)(liu)電(dian)(dian)(dian)轉換為(wei)低壓(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)的供電(dian)(dian)(dian)設備，采(cai)用電(dian)(dian)(dian)力電(dian)(dian)(dian)子半導體器(qi)(qi)件，將電(dian)(dian)(dian)壓(ya)和(he)頻率固定不變的交流(liu)(liu)(liu)電(dian)(dian)(dian)變換為(wei)直流(liu)(liu)(liu)電(dian)(dian)(dian)的一(yi)(yi)種靜止變流(liu)(liu)(liu)裝置。

2.適配(pei)(pei)器就是(shi)一個接(jie)(jie)口(kou)(kou)轉(zhuan)移器，一般(ban)由外殼、電(dian)(dian)(dian)源(yuan)變壓器和整(zheng)流電(dian)(dian)(dian)路組成，適用于小(xiao)型便攜式電(dian)(dian)(dian)子設(she)備(bei)(bei)及電(dian)(dian)(dian)子電(dian)(dian)(dian)器的(de)供電(dian)(dian)(dian)電(dian)(dian)(dian)源(yuan)變換設(she)備(bei)(bei)。適配(pei)(pei)器可以是(shi)一個獨立的(de)硬件接(jie)(jie)口(kou)(kou)設(she)備(bei)(bei)，也可以是(shi)信息接(jie)(jie)口(kou)(kou)。通常使用的(de)適配(pei)(pei)器一般(ban)有電(dian)(dian)(dian)源(yuan)適配(pei)(pei)器、USB與串口(kou)(kou)的(de)轉(zhuan)接(jie)(jie)設(she)備(bei)(bei)等。

總結：充(chong)(chong)電(dian)器是包括(kuo)了適(shi)配器功(gong)能的，它比適(shi)配器多一個控制電(dian)路。適(shi)配器只(zhi)起到穩壓作(zuo)用，充(chong)(chong)電(dian)器具有恒流和限壓設計。
