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)般都兼備兩種(zhong)(zhong)充電(dian)(dian)(dian)措施，一(yi)種(zhong)(zhong)是帶機充電(dian)(dian)(dian)（充電(dian)(dian)(dian)器通(tong)(tong)過(guo)電(dian)(dian)(dian)連接(jie)器與手機配合(he)給(gei)(gei)電(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)）；另一(yi)種(zhong)(zhong)是通(tong)(tong)過(guo)充電(dian)(dian)(dian)座(zuo)給(gei)(gei)電(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)。選購前(qian)，應(ying)清楚自(zi)己所用電(dian)(dian)(dian)池(chi)(chi)的(de)類(lei)型(xing)、容(rong)量(liang)、標(biao)(biao)稱(cheng)電(dian)(dian)(dian)壓(ya)(ya)(ya)，以便選購與之(zhi)適配的(de)充電(dian)(dian)(dian)器。 3、目前(qian)手機使(shi)用的(de)電(dian)(dian)(dian)池(chi)(chi)幾乎都是只有一(yi)個單體電(dian)(dian)(dian)芯、標(biao)(biao)稱(cheng)電(dian)(dian)(dian)壓(ya)(ya)(ya)為(wei)3.6V、額定容(rong)量(liang)為(wei)500mAh～1000mAh的(de)鋰離(li)(li)子電(dian)(dian)(dian)池(chi)(chi)。鋰離(li)(li)子電(dian)(dian)(dian)芯對充電(dian)(dian)(dian)電(dian)(dian)(dian)流和充電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)要求非常高(gao)；充電(dian)(dian)(dian)電(dian)(dian)(dian)流過(guo)大或充電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)(ya)過(guo)高(gao)，會引起(qi)電(dian)(dian)(dian)芯內部化學(xue)反(fan)應(ying)巨(ju)變，使(shi)得(de)內部溫度(du)升高(gao)，導(dao)致電(dian)(dian)(dian)極、隔膜材料損壞或電(dian)(dian)(dian)芯膨(peng)脹爆炸。雖然，一(yi)般手機電(dian)(dian)(dian)池(chi)(chi)內部裝(zhuang)有具有過(guo)充、過(guo)放、過(guo)流保護功能的(de)保護器。但(dan)為(wei)了安全、為(wei)了達到較好的(de)充電(dian)(dian)(dian)效果，應(ying)選購最(zui)大輸(shu)出(chu)電(dian)(dian)(dian)壓(ya)(ya)(ya)為(wei)4.2V～4.5V、最(zui)大輸(shu)出(chu)電(dian)(dian)(dian)流為(wei)600mA～700mA的(de)充電(dian)(dian)(dian)器。

    規范的充電器產(chan)品(pin)都應標明其(qi)(qi)使(shi)用(yong)范(fan)圍、輸(shu)出(chu)(chu)電(dian)(dian)(dian)壓和輸(shu)出(chu)(chu)電(dian)(dian)(dian)流(liu)等技(ji)術參(can)數。有(you)條件的話，選購(gou)時可(ke)用(yong)萬用(yong)表的適當(dang)測(ce)量(liang)檔測(ce)量(liang)充電(dian)(dian)(dian)器的輸(shu)出(chu)(chu)空(kong)載電(dian)(dian)(dian)壓和輸(shu)出(chu)(chu)短路(lu)電(dian)(dian)(dian)流(liu)，判(pan)斷其(qi)(qi)實際數據是(shi)否與所標技(ji)術參(can)數一致。 另(ling)外，建議應到(dao)信譽較(jiao)好、規模(mo)較(jiao)大的電(dian)(dian)(dian)訊電(dian)(dian)(dian)器專賣(mai)店選購(gou)。
