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(jian)備兩種充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)措施，一種是(shi)(shi)帶機(ji)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)（充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)通過(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)連接(jie)器(qi)(qi)與手機(ji)配合給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)）；另一種是(shi)(shi)通過(guo)(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)座(zuo)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。選購(gou)前，應(ying)(ying)清(qing)楚自己所用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)類型、容量、標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，以便選購(gou)與之(zhi)適配的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。 3、目前手機(ji)使用(yong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池幾乎都是(shi)(shi)只有一個(ge)單(dan)體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯、標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓為3.6V、額定容量為500mAh～1000mAh的(de)(de)鋰離子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池。鋰離子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯對(dui)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)和充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)要(yao)求(qiu)非常(chang)高(gao)(gao)；充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)過(guo)(guo)大或充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓過(guo)(guo)高(gao)(gao)，會引起電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯內部(bu)化(hua)學反應(ying)(ying)巨(ju)變，使得(de)內部(bu)溫度升高(gao)(gao)，導致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極、隔膜材料損壞或電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯膨脹(zhang)爆(bao)炸。雖(sui)然，一般手機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池內部(bu)裝有具有過(guo)(guo)充(chong)(chong)、過(guo)(guo)放、過(guo)(guo)流(liu)保護功(gong)能的(de)(de)保護器(qi)(qi)。但為了(le)安(an)全、為了(le)達到(dao)較好的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)效果，應(ying)(ying)選購(gou)最大輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓為4.2V～4.5V、最大輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)為600mA～700mA的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。

    規范的充電器產(chan)品都應(ying)標明其使用(yong)范圍、輸(shu)出電(dian)壓和(he)輸(shu)出電(dian)流(liu)等技術參數(shu)。有條件的(de)話，選購時可用(yong)萬用(yong)表的(de)適當測量檔測量充電(dian)器的(de)輸(shu)出空載(zai)電(dian)壓和(he)輸(shu)出短(duan)路電(dian)流(liu)，判斷其實際數(shu)據是否與所標技術參數(shu)一致(zhi)。 另外，建議應(ying)到信譽較(jiao)好、規模較(jiao)大的(de)電(dian)訊電(dian)器專賣店選購。
