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(yi)般都兼(jian)備兩(liang)種(zhong)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)措施，一(yi)種(zhong)是(shi)帶機(ji)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)（充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)通(tong)過(guo)(guo)電(dian)(dian)(dian)(dian)連接器(qi)與(yu)手機(ji)配合給電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)）；另一(yi)種(zhong)是(shi)通(tong)過(guo)(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)座給電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。選(xuan)購(gou)前，應清楚自己所(suo)用(yong)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)類型、容量(liang)、標(biao)稱(cheng)電(dian)(dian)(dian)(dian)壓(ya)，以便選(xuan)購(gou)與(yu)之適配的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)。 3、目前手機(ji)使用(yong)的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)幾(ji)乎都是(shi)只有一(yi)個單體電(dian)(dian)(dian)(dian)芯、標(biao)稱(cheng)電(dian)(dian)(dian)(dian)壓(ya)為(wei)(wei)3.6V、額定容量(liang)為(wei)(wei)500mAh～1000mAh的(de)鋰(li)離子電(dian)(dian)(dian)(dian)池(chi)(chi)。鋰(li)離子電(dian)(dian)(dian)(dian)芯對充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)和充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)的(de)要求非常(chang)高(gao)(gao)；充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)過(guo)(guo)大(da)或充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)過(guo)(guo)高(gao)(gao)，會引(yin)起電(dian)(dian)(dian)(dian)芯內部(bu)化學反(fan)應巨(ju)變，使得內部(bu)溫(wen)度升高(gao)(gao)，導致電(dian)(dian)(dian)(dian)極、隔膜材料損壞或電(dian)(dian)(dian)(dian)芯膨脹爆炸(zha)。雖然，一(yi)般手機(ji)電(dian)(dian)(dian)(dian)池(chi)(chi)內部(bu)裝有具有過(guo)(guo)充(chong)(chong)(chong)、過(guo)(guo)放、過(guo)(guo)流(liu)(liu)保(bao)護(hu)(hu)功(gong)能的(de)保(bao)護(hu)(hu)器(qi)。但為(wei)(wei)了(le)安全(quan)、為(wei)(wei)了(le)達到較好的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)效(xiao)果，應選(xuan)購(gou)最大(da)輸出電(dian)(dian)(dian)(dian)壓(ya)為(wei)(wei)4.2V～4.5V、最大(da)輸出電(dian)(dian)(dian)(dian)流(liu)(liu)為(wei)(wei)600mA～700mA的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)。

    規范的充電器產(chan)品都應標明其(qi)使用范圍、輸(shu)出(chu)電(dian)壓(ya)和(he)輸(shu)出(chu)電(dian)流等技術參(can)數。有條件的(de)話，選購時可用萬用表的(de)適當測量檔測量充電(dian)器的(de)輸(shu)出(chu)空載電(dian)壓(ya)和(he)輸(shu)出(chu)短(duan)路電(dian)流，判斷其(qi)實際數據是否與(yu)所標技術參(can)數一致。 另外，建議應到信譽較(jiao)好、規模較(jiao)大的(de)電(dian)訊電(dian)器專賣店選購。
