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)(yi)般(ban)都兼備兩種充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)措施(shi)，一(yi)(yi)種是帶機(ji)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)（充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)通(tong)過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)連(lian)接器(qi)與手(shou)機(ji)配合給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)）；另一(yi)(yi)種是通(tong)過(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)座給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。選購(gou)前，應清楚自己(ji)所用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的類型、容量、標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，以便(bian)選購(gou)與之適配的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。 3、目前手(shou)機(ji)使(shi)用(yong)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)幾乎都是只有(you)一(yi)(yi)個單體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)(xin)、標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為3.6V、額(e)定容量為500mAh～1000mAh的鋰離(li)子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。鋰離(li)子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)(xin)對充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)和充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的要求非常高；充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)過(guo)大或充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)過(guo)高，會(hui)引起(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)(xin)內(nei)部(bu)化學反應巨變，使(shi)得內(nei)部(bu)溫度升高，導(dao)致電(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)芯(xin)(xin)膨脹(zhang)爆炸(zha)。雖(sui)然，一(yi)(yi)般(ban)手(shou)機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)內(nei)部(bu)裝有(you)具有(you)過(guo)充(chong)(chong)(chong)、過(guo)放、過(guo)流(liu)(liu)保護功(gong)能的保護器(qi)。但為了安全、為了達(da)到較(jiao)好的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)效果，應選購(gou)最(zui)大輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為4.2V～4.5V、最(zui)大輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)為600mA～700mA的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。

    規范的充電器產(chan)品都(dou)應標明其使用范圍(wei)、輸(shu)(shu)出(chu)電(dian)(dian)(dian)壓和輸(shu)(shu)出(chu)電(dian)(dian)(dian)流等技術參數。有條(tiao)件的話，選(xuan)購(gou)時(shi)可(ke)用萬用表的適當測量檔測量充電(dian)(dian)(dian)器的輸(shu)(shu)出(chu)空(kong)載電(dian)(dian)(dian)壓和輸(shu)(shu)出(chu)短路電(dian)(dian)(dian)流，判(pan)斷其實(shi)際數據是否與所標技術參數一致。 另外，建議應到信譽較(jiao)好、規模較(jiao)大的電(dian)(dian)(dian)訊電(dian)(dian)(dian)器專賣店選(xuan)購(gou)。
