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(liang)種充(chong)(chong)電(dian)(dian)措施，一(yi)種是帶機充(chong)(chong)電(dian)(dian)（充(chong)(chong)電(dian)(dian)器通過(guo)電(dian)(dian)連(lian)接器與手機配(pei)合給電(dian)(dian)池充(chong)(chong)電(dian)(dian)）；另一(yi)種是通過(guo)充(chong)(chong)電(dian)(dian)座(zuo)給電(dian)(dian)池充(chong)(chong)電(dian)(dian)。選(xuan)購(gou)前(qian)，應清楚(chu)自(zi)己所用電(dian)(dian)池的類(lei)型、容量、標稱(cheng)電(dian)(dian)壓(ya)(ya)，以便選(xuan)購(gou)與之適配(pei)的充(chong)(chong)電(dian)(dian)器。 3、目(mu)前(qian)手機使(shi)用的電(dian)(dian)池幾乎都是只有一(yi)個(ge)單體電(dian)(dian)芯(xin)、標稱(cheng)電(dian)(dian)壓(ya)(ya)為(wei)3.6V、額定容量為(wei)500mAh～1000mAh的鋰離子(zi)電(dian)(dian)池。鋰離子(zi)電(dian)(dian)芯(xin)對充(chong)(chong)電(dian)(dian)電(dian)(dian)流和充(chong)(chong)電(dian)(dian)電(dian)(dian)壓(ya)(ya)的要(yao)求非常(chang)高；充(chong)(chong)電(dian)(dian)電(dian)(dian)流過(guo)大(da)或充(chong)(chong)電(dian)(dian)電(dian)(dian)壓(ya)(ya)過(guo)高，會引起(qi)電(dian)(dian)芯(xin)內(nei)部化學反應巨變，使(shi)得(de)內(nei)部溫度升高，導(dao)致電(dian)(dian)極、隔(ge)膜材料損壞或電(dian)(dian)芯(xin)膨(peng)脹爆炸。雖然，一(yi)般手機電(dian)(dian)池內(nei)部裝(zhuang)有具有過(guo)充(chong)(chong)、過(guo)放、過(guo)流保(bao)護功能的保(bao)護器。但為(wei)了安全、為(wei)了達到較好的充(chong)(chong)電(dian)(dian)效果，應選(xuan)購(gou)最(zui)大(da)輸(shu)出電(dian)(dian)壓(ya)(ya)為(wei)4.2V～4.5V、最(zui)大(da)輸(shu)出電(dian)(dian)流為(wei)600mA～700mA的充(chong)(chong)電(dian)(dian)器。

    規范的充電器產品都應(ying)(ying)標(biao)明(ming)其使(shi)用范(fan)圍、輸出(chu)(chu)電壓(ya)和輸出(chu)(chu)電流(liu)等技術參數(shu)。有條(tiao)件的(de)話，選(xuan)(xuan)購時可用萬用表的(de)適當(dang)測(ce)量(liang)檔測(ce)量(liang)充電器(qi)的(de)輸出(chu)(chu)空載電壓(ya)和輸出(chu)(chu)短路(lu)電流(liu)，判斷(duan)其實際數(shu)據是否(fou)與所標(biao)技術參數(shu)一致(zhi)。 另外，建議應(ying)(ying)到信譽較好、規(gui)模較大的(de)電訊(xun)電器(qi)專賣店選(xuan)(xuan)購。
