作為消費者，選購一個質量較好、適合使用的充電器產品以下幾點可供參考： 1、選購電池充電器時，應詳細閱讀產品使用說明書或產品標記說明。一般來說，有產品認證標志的充電器才有安全保證。因此，應盡量選購有產品認證標志的產品。 2、手機充電器一般都兼備兩種(zhong)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)措施，一種(zhong)是帶機(ji)(ji)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)（充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器通(tong)過(guo)(guo)(guo)電(dian)(dian)(dian)(dian)(dian)連接器與手(shou)機(ji)(ji)配(pei)合給電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)）；另(ling)一種(zhong)是通(tong)過(guo)(guo)(guo)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)座(zuo)給電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。選購前，應(ying)(ying)清楚自己所用電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)類(lei)型、容量(liang)、標稱電(dian)(dian)(dian)(dian)(dian)壓，以便選購與之(zhi)適配(pei)的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器。 3、目(mu)前手(shou)機(ji)(ji)使(shi)用的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)幾乎都是只有(you)一個單體(ti)電(dian)(dian)(dian)(dian)(dian)芯(xin)、標稱電(dian)(dian)(dian)(dian)(dian)壓為(wei)3.6V、額定容量(liang)為(wei)500mAh～1000mAh的(de)鋰離子電(dian)(dian)(dian)(dian)(dian)池(chi)。鋰離子電(dian)(dian)(dian)(dian)(dian)芯(xin)對充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)和(he)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓的(de)要求非(fei)常高；充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)過(guo)(guo)(guo)大(da)或充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓過(guo)(guo)(guo)高，會引起電(dian)(dian)(dian)(dian)(dian)芯(xin)內(nei)部化(hua)學(xue)反應(ying)(ying)巨變，使(shi)得內(nei)部溫度升高，導致電(dian)(dian)(dian)(dian)(dian)極、隔膜(mo)材料損壞或電(dian)(dian)(dian)(dian)(dian)芯(xin)膨脹爆炸。雖然，一般手(shou)機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)池(chi)內(nei)部裝(zhuang)有(you)具有(you)過(guo)(guo)(guo)充(chong)(chong)(chong)(chong)、過(guo)(guo)(guo)放、過(guo)(guo)(guo)流(liu)保護(hu)功能的(de)保護(hu)器。但為(wei)了安全、為(wei)了達到較好的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)效果，應(ying)(ying)選購最(zui)大(da)輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓為(wei)4.2V～4.5V、最(zui)大(da)輸出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)為(wei)600mA～700mA的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器。

    規范的充電器產品都應(ying)標明(ming)其使用(yong)(yong)范圍、輸出電(dian)壓和輸出電(dian)流等技(ji)術(shu)參(can)數。有(you)條件的(de)話，選購(gou)時可用(yong)(yong)萬用(yong)(yong)表的(de)適(shi)當(dang)測量檔測量充電(dian)器(qi)的(de)輸出空載(zai)電(dian)壓和輸出短路電(dian)流，判斷其實際數據是否與(yu)所標技(ji)術(shu)參(can)數一(yi)致。 另外，建(jian)議應(ying)到(dao)信譽較好(hao)、規模較大的(de)電(dian)訊電(dian)器(qi)專賣店選購(gou)。
