智能(neng)(neng)智能(neng)(neng)手機(ji)(ji)的(de)全(quan)面普(pu)及普(pu)及以后(hou)，絕(jue)大數人會(hui)隨身攜帶一部甚(shen)至兩部手機(ji)(ji)。雖然(ran)經過多(duo)年的(de)技術革新，手機(ji)(ji)等便(bian)攜電(dian)子設備的(de)安(an)全(quan)性(xing)逐(zhu)步提升，但(dan)沒有一家廠商能(neng)(neng)夠保證(zheng)自己的(de)產品百分之(zhi)百的(de)安(an)全(quan)，便(bian)攜產品的(de)安(an)全(quan)性(xing)仍是大眾(zhong)擔憂(you)的(de)問題。那么(me)如何提高手機(ji)(ji)等便(bian)攜電(dian)子設備的(de)安(an)全(quan)性(xing)呢？有時關鍵往往在最不起眼的(de)身上。

所謂的(de)手(shou)(shou)機(ji)(ji)充(chong)電(dian)(dian)(dian)器(qi)通常(chang)就是交(jiao)流(liu)/直流(liu)（AC-DC）電(dian)(dian)(dian)源適配器(qi)，真(zhen)正的(de)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)路在手(shou)(shou)機(ji)(ji)內部。根(gen)據YD/T 1591標(biao)準(zhun)要求，手(shou)(shou)機(ji)(ji)充(chong)電(dian)(dian)(dian)接口直流(liu)輸入電(dian)(dian)(dian)壓也就是充(chong)電(dian)(dian)(dian)器(qi)的(de)輸出(chu)(chu)電(dian)(dian)(dian)壓為(wei)5V±5%，即4.75V~5.25V；標(biao)準(zhun)充(chong)電(dian)(dian)(dian)器(qi)的(de)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)為(wei)300mA至1800mA，非標(biao)準(zhun)充(chong)電(dian)(dian)(dian)器(qi)（如筆記本電(dian)(dian)(dian)腦的(de)USB端口等）的(de)最大(da)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)為(wei)500mA。無論充(chong)電(dian)(dian)(dian)器(qi)的(de)輸出(chu)(chu)功率如何(he)，手(shou)(shou)持機(ji)(ji)側(ce)充(chong)電(dian)(dian)(dian)控制電(dian)(dian)(dian)路應能根(gen)據自身(shen)需求實施(shi)安全充(chong)電(dian)(dian)(dian)，不應出(chu)(chu)現(xian)電(dian)(dian)(dian)池過熱、燃燒、爆(bao)炸以及其它電(dian)(dian)(dian)路損壞的(de)現(xian)象。

手機側充電控制電路(lu)應(ying)具備過壓(ya)(ya)保(bao)護裝(zhuang)置，也(ye)就是在(zai)手機充電接口導入6V以上直流電壓(ya)(ya)時，如(ru)果不能(neng)保(bao)證安全充電，應(ying)啟動保(bao)護，在(zai)非預期電壓(ya)(ya)下(xia)，不應(ying)出現(xian)過熱、燃燒、爆(bao)炸以及(ji)其它(ta)電路(lu)損壞的(de)現(xian)象，且(qie)在(zai)電壓(ya)(ya)恢復(fu)后，手機應(ying)能(neng)正常工作。

過壓(ya)保護能夠很(hen)好(hao)的(de)(de)保護電子(zi)設備在高壓(ya)下不(bu)受損害，但(dan)是問題往(wang)往(wang)出現在細小處(chu)，目前市面上許多的(de)(de)電源適配(pei)器為了節省成本，本身并沒有保護電路。所以想要提(ti)高便攜電子(zi)設備的(de)(de)安全性，其中重要的(de)(de)一點就是要著(zhu)重提(ti)高電源適配(pei)器的(de)(de)質量。
