出(chu)門在外(wai)，手機沒電時，身(shen)旁如果有充電器的話通常都是拿(na)起來直接充，像這樣的混(hun)充經歷相信(xin)大(da)家都有過吧(ba)。有人(ren)認為這樣做很危險(xian)，有人(ren)覺得沒問題，那么(me)到底可不(bu)可以混(hun)充呢？我們(men)先來看(kan)看(kan)手(shou)機充電器的工作原(yuan)理吧。

　從(cong)充電(dian)(dian)(dian)器(qi)方面來說(shuo)(shuo)，一般充電(dian)(dian)(dian)器(qi)都會(hui)內置智(zhi)能芯片，可以自(zi)動識(shi)(shi)別手(shou)機(ji)所需(xu)的電(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)壓，然后自(zi)行調(diao)整，從(cong)而給(gei)手(shou)機(ji)提供安全范圍(wei)內的電(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)壓。比如，用快(kuai)充充電(dian)(dian)(dian)器(qi)，給(gei)不支(zhi)持快(kuai)充的手(shou)機(ji)充電(dian)(dian)(dian)，那么充電(dian)(dian)(dian)器(qi)就(jiu)會(hui)識(shi)(shi)別到(dao)這(zhe)部手(shou)機(ji)無法快(kuai)充，從(cong)而調(diao)整為普通充電(dian)(dian)(dian)模式(shi)。從(cong)手(shou)機(ji)本身來說(shuo)(shuo)，手(shou)機(ji)內部也有電(dian)(dian)(dian)路自(zi)動控制系(xi)統，可以起到(dao)過(guo)流(liu)、過(guo)壓等保護(hu)作用，防止過(guo)高的電(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)壓進(jin)入(ru)和(he)損壞手(shou)機(ji)。

關于混用手機充電器，給大家(jia)一(yi)下幾(ji)點建議

1、大電(dian)流的充(chong)電(dian)器給小電(dian)流手機充(chong)電(dian)，結果幾(ji)乎不(bu)會(hui)有影響，充(chong)電(dian)速(su)度也(ye)不(bu)會(hui)加(jia)快。

2、小電(dian)(dian)流可(ke)以給大電(dian)(dian)流手機充電(dian)(dian)，不(bu)過(guo)速度慢，充電(dian)(dian)器也(ye)會長時間在負載(zai)狀態，造成充電(dian)(dian)器過(guo)熱，容易造成充電(dian)(dian)器老化速度加快，不(bu)建議經常使(shi)用。

3、建(jian)議能使用(yong)原裝充(chong)電(dian)器就用(yong)原裝的，如果(guo)另外配充(chong)電(dian)器的話，不建(jian)議使用(yong)1A以(yi)下的(de)充電器。
