在現實生(sheng)活中許(xu)多人連(lian)和充電(dian)器(qi)都分(fen)不清(qing)，更不要(yao)說內置電(dian)源(yuan)和非內置電(dian)源(yuan)了，但(dan)其實這些都是(shi)我們生活中經(jing)常(chang)接觸的東西，也(ye)并不難理解，接下(xia)來電(dian)源(yuan)適配器(qi)廠(chang)家(jia)就來為大家(jia)詳細說說二者的區(qu)別(bie)吧(ba)。

　　內置電(dian)(dian)源(yuan)(yuan)(yuan)與(yu)非內置電(dian)(dian)源(yuan)(yuan)(yuan)充(chong)電(dian)(dian)器(qi)是(shi)(shi)按是(shi)(shi)否內置有降壓穩(wen)壓模塊來區(qu)分的(de)。充(chong)電(dian)(dian)器(qi)的(de)工(gong)作(zuo)電(dian)(dian)壓常見都是(shi)(shi)11~18V為主，也(ye)有一(yi)些是(shi)(shi)24V的(de)，但是(shi)(shi)僅限一(yi)些超(chao)大功率(lv)的(de)機(ji)型(xing)。而我(wo)們家庭(ting)用(yong)電(dian)(dian)則是(shi)(shi)220V，于是(shi)(shi)都需要一(yi)套降壓設備，也(ye)就是(shi)(shi)電(dian)(dian)源(yuan)(yuan)(yuan)適配器(qi)，來供電(dian)(dian)給充(chong)電(dian)(dian)器(qi)。

　　絕大(da)(da)(da)(da)多數(shu)充(chong)電(dian)(dian)(dian)(dian)器(qi)，其實都不是內(nei)置電(dian)(dian)(dian)(dian)源。原因一(yi)般(ban)(ban)如下(xia)：首先因為專業的(de)(de)充(chong)電(dian)(dian)(dian)(dian)器(qi)，多數(shu)功(gong)率都十分大(da)(da)(da)(da)，而(er)大(da)(da)(da)(da)功(gong)率的(de)(de)電(dian)(dian)(dian)(dian)源多數(shu)體積(ji)會(hui)更加龐大(da)(da)(da)(da)，不適(shi)合內(nei)置到充(chong)電(dian)(dian)(dian)(dian)器(qi)里面(mian)。因此(ci)，一(yi)般(ban)(ban)內(nei)置有電(dian)(dian)(dian)(dian)源的(de)(de)充(chong)電(dian)(dian)(dian)(dian)器(qi)，功(gong)率一(yi)般(ban)(ban)不會(hui)太大(da)(da)(da)(da)，比較少有超過100W的(de)(de)充(chong)電(dian)(dian)(dian)(dian)功(gong)率。像(xiang)我們(men)常用的(de)(de)筆記本(ben)電(dian)(dian)(dian)(dian)腦它就(jiu)不是內(nei)置電(dian)(dian)(dian)(dian)源。

　　內(nei)置(zhi)電(dian)源(yuan)的充電(dian)器在(zai)充電(dian)器內(nei)部內(nei)置(zhi)有(you)電(dian)源(yuan)適配器，我(wo)們(men)不(bu)需要(yao)額外(wai)(wai)購置(zhi)電(dian)源(yuan)就(jiu)可(ke)以(yi)使(shi)用。一(yi)般(ban)功率(lv)不(bu)會太(tai)大，但是(shi)(shi)也(ye)有(you)一(yi)些(xie)功率(lv)比較大的內(nei)置(zhi)電(dian)源(yuan)充電(dian)器一(yi)般(ban)都同(tong)時支持外(wai)(wai)接電(dian)源(yuan)，也(ye)就(jiu)是(shi)(shi)既可(ke)以(yi)使(shi)用內(nei)置(zhi)電(dian)源(yuan)，也(ye)可(ke)以(yi)使(shi)用外(wai)(wai)置(zhi)電(dian)源(yuan)。

　　缺點是(shi)需要額外(wai)(wai)配套(tao)電(dian)源適(shi)配器才可(ke)以使(shi)(shi)用(yong)，有時(shi)使(shi)(shi)用(yong)起來不太方(fang)便(bian)。內(nei)置(zhi)電(dian)源充電(dian)器的優(you)點：對普通人來說使(shi)(shi)用(yong)方(fang)便(bian)很(hen)多，隨時(shi)接220V即可(ke)使(shi)(shi)用(yong)，不需要再(zai)額外(wai)(wai)接電(dian)源適(shi)配器。除(chu)了這(zhe)些，電(dian)源適(shi)配器廠家還建議多了解一些其他的電(dian)源知識，這(zhe)樣平時(shi)在(zai)使(shi)(shi)用(yong)電(dian)源適(shi)配器的時(shi)候也不會(hui)弄(nong)錯(cuo)弄(nong)混了。
