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)電(dian)(dian)(dian)(dian)措施，一種(zhong)是帶機(ji)充(chong)(chong)電(dian)(dian)(dian)(dian)（充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)通過(guo)電(dian)(dian)(dian)(dian)連接器(qi)(qi)與手機(ji)配合(he)給(gei)電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)）；另一種(zhong)是通過(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)座給(gei)電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)。選購(gou)前，應清楚自己所用電(dian)(dian)(dian)(dian)池(chi)的(de)類(lei)型(xing)、容量、標(biao)稱電(dian)(dian)(dian)(dian)壓(ya)，以便選購(gou)與之適配的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)。 3、目前手機(ji)使用的(de)電(dian)(dian)(dian)(dian)池(chi)幾乎(hu)都是只有(you)一個單(dan)體電(dian)(dian)(dian)(dian)芯(xin)、標(biao)稱電(dian)(dian)(dian)(dian)壓(ya)為(wei)3.6V、額定(ding)容量為(wei)500mAh～1000mAh的(de)鋰離子(zi)(zi)電(dian)(dian)(dian)(dian)池(chi)。鋰離子(zi)(zi)電(dian)(dian)(dian)(dian)芯(xin)對充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流和充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)的(de)要求非(fei)常(chang)高(gao)；充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流過(guo)大(da)或充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)過(guo)高(gao)，會引起(qi)電(dian)(dian)(dian)(dian)芯(xin)內(nei)部(bu)化學反(fan)應巨變(bian)，使得內(nei)部(bu)溫度升高(gao)，導致電(dian)(dian)(dian)(dian)極、隔膜材料損壞或電(dian)(dian)(dian)(dian)芯(xin)膨脹(zhang)爆炸。雖(sui)然，一般手機(ji)電(dian)(dian)(dian)(dian)池(chi)內(nei)部(bu)裝有(you)具有(you)過(guo)充(chong)(chong)、過(guo)放、過(guo)流保護(hu)功(gong)能的(de)保護(hu)器(qi)(qi)。但為(wei)了(le)安全、為(wei)了(le)達(da)到較好的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)效果(guo)，應選購(gou)最大(da)輸(shu)出電(dian)(dian)(dian)(dian)壓(ya)為(wei)4.2V～4.5V、最大(da)輸(shu)出電(dian)(dian)(dian)(dian)流為(wei)600mA～700mA的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)。

    規范的充電器產品都應(ying)標明(ming)其使用(yong)范圍、輸出電壓(ya)(ya)和輸出電流等技術參(can)數。有條件的話，選購(gou)時可(ke)用(yong)萬用(yong)表的適(shi)當測(ce)量檔測(ce)量充電器的輸出空(kong)載電壓(ya)(ya)和輸出短路電流，判斷其實際數據是否與所標技術參(can)數一致。 另外，建議應(ying)到(dao)信譽較(jiao)(jiao)好、規模較(jiao)(jiao)大的電訊電器專賣店選購(gou)。
