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(ban)都兼備兩種(zhong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)措施，一(yi)種(zhong)是(shi)(shi)(shi)帶機充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)（充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)通過(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)連(lian)接器(qi)與(yu)手機配合給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)）；另一(yi)種(zhong)是(shi)(shi)(shi)通過(guo)(guo)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)座給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。選購(gou)前，應清楚(chu)自己所(suo)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)類型(xing)、容量(liang)、標稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，以便(bian)選購(gou)與(yu)之適(shi)配的(de)(de)(de)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。 3、目前手機使(shi)用(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)幾(ji)乎(hu)都是(shi)(shi)(shi)只(zhi)有一(yi)個單體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯、標稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為3.6V、額定容量(liang)為500mAh～1000mAh的(de)(de)(de)鋰(li)離(li)子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。鋰(li)離(li)子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯對(dui)充(chong)(chong)(chong)(chong)(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)(chong)(chong)(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(ya)的(de)(de)(de)要求非常高；充(chong)(chong)(chong)(chong)(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(da)(da)或(huo)充(chong)(chong)(chong)(chong)(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(ya)過(guo)(guo)高，會引(yin)起電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯內部化學反應巨(ju)變(bian)，使(shi)得(de)內部溫度升高，導致(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極、隔膜材(cai)料(liao)損(sun)壞或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯膨脹(zhang)爆(bao)炸。雖(sui)然，一(yi)般(ban)手機電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)內部裝有具有過(guo)(guo)充(chong)(chong)(chong)(chong)(chong)(chong)、過(guo)(guo)放、過(guo)(guo)流(liu)保護功能(neng)的(de)(de)(de)保護器(qi)。但為了安(an)全、為了達(da)到較好(hao)的(de)(de)(de)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)效(xiao)果(guo)，應選購(gou)最大(da)(da)輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為4.2V～4.5V、最大(da)(da)輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)為600mA～700mA的(de)(de)(de)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。

    規范的充電器產品都(dou)應(ying)(ying)標明(ming)其使用范圍(wei)、輸(shu)(shu)(shu)出電壓(ya)和輸(shu)(shu)(shu)出電流等技(ji)(ji)術(shu)(shu)參數(shu)。有(you)條件(jian)的話，選購時可用萬(wan)用表的適當測量檔測量充電器(qi)的輸(shu)(shu)(shu)出空載(zai)電壓(ya)和輸(shu)(shu)(shu)出短路電流，判斷其實際數(shu)據是否與(yu)所標技(ji)(ji)術(shu)(shu)參數(shu)一致。 另外，建議應(ying)(ying)到信譽較好、規模較大的電訊電器(qi)專賣店選購。
