電源適配器在居民生活中使用非常廣泛，從80年代的穩壓器到現在筆記本電腦的充電器都可以稱得上是，隨著科技的發達，現在的電源適配器逐漸越來越小，其能提供的功能卻沒有改變，在此為大家介紹電源適配器能夠實現的五大核心功能。

 1. 調(diao)整輸(shu)入輸(shu)出電(dian)(dian)(dian)(dian)壓，筆(bi)記本電(dian)(dian)(dian)(dian)腦的電(dian)(dian)(dian)(dian)源適配器可以(yi)應對(dui)于100V—240V的電(dian)(dian)(dian)(dian)壓區間，也(ye)就是(shi)無論您身在何處，筆(bi)記本電(dian)(dian)(dian)(dian)腦都是(shi)可以(yi)即(ji)插即(ji)用的，不需要電(dian)(dian)(dian)(dian)源轉換(huan)器;

2.其(qi)(qi)輸出(chu)的(de)(de)電壓是按照(zhao)筆記本大小及電容(rong)量的(de)(de)要(yao)求的(de)(de)，一般會(hui)選擇數(shu)安到(dao)數(shu)十(shi)安不等(deng)，但是規格還是按照(zhao)屏(ping)幕越大其(qi)(qi)電量耗費越多;

3. 就(jiu)是(shi)保護電(dian)(dian)腦元件(jian)，如果(guo)沒有(you)電(dian)(dian)源適配(pei)(pei)器，筆(bi)記本直接插(cha)到插(cha)口(kou)中(zhong)使(shi)用(yong)將(jiang)會燒壞原件(jian)和電(dian)(dian)池(chi)，其(qi)主要(yao)原因是(shi)負(fu)載(zai)(zai)等問題，而電(dian)(dian)源設(she)配(pei)(pei)器也就(jiu)是(shi)將(jiang)電(dian)(dian)流控制在(zai)筆(bi)記本要(yao)求的電(dian)(dian)量(liang)負(fu)荷內，保證其(qi)在(zai)正常使(shi)用(yong)的過程(cheng)中(zhong)不因為電(dian)(dian)量(liang)負(fu)載(zai)(zai)帶來安全隱患(huan);

4. 能(neng)夠(gou)保護電(dian)(dian)(dian)池(chi)，其(qi)對于(yu)輸(shu)入電(dian)(dian)(dian)壓進行(xing)分流(liu)和(he)穩(wen)壓，對于(yu)電(dian)(dian)(dian)流(liu)中的雜質(zhi)和(he)雜波進行(xing)過濾，給于(yu)電(dian)(dian)(dian)池(chi)穩(wen)定的電(dian)(dian)(dian)壓動(dong)力，對于(yu)忽然斷(duan)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓的倒灌等(deng)問題也能(neng)承(cheng)載(zai)下來，進一步保證了其(qi)電(dian)(dian)(dian)池(chi)的使用(yong)(yong)壽命(ming)。在使用(yong)(yong)過程中，電(dian)(dian)(dian)源(yuan)適配器也會默(mo)認將電(dian)(dian)(dian)流(liu)輸(shu)送給本機(ji)使用(yong)(yong)和(he)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)，電(dian)(dian)(dian)池(chi)充(chong)滿后會通過充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)控制設備向適配器發送信號，從(cong)而形成斷(duan)電(dian)(dian)(dian)，這也是其(qi)電(dian)(dian)(dian)源(yuan)適配器的功能(neng)之(zhi)一;

5. 電(dian)(dian)源適配器也(ye)能(neng)幫助(zhu)筆(bi)(bi)記本(ben)電(dian)(dian)腦(nao)(nao)降溫，不會因(yin)為忽(hu)然斷電(dian)(dian)或者(zhe)是其他(ta)問(wen)題形成的(de)安(an)全事故，對于(yu)穩(wen)壓(ya)方面提供(gong)的(de)電(dian)(dian)流(liu)也(ye)能(neng)更方便(bian)筆(bi)(bi)記本(ben)電(dian)(dian)腦(nao)(nao)使用(yong)。
