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(ban)都兼備兩種(zhong)(zhong)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)措(cuo)施，一種(zhong)(zhong)是帶機(ji)(ji)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)（充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)通(tong)過(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)連接器(qi)(qi)與手機(ji)(ji)配(pei)合(he)給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)）；另一種(zhong)(zhong)是通(tong)過(guo)(guo)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)座給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。選(xuan)購前(qian)，應(ying)(ying)清楚自己(ji)所用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)類型、容(rong)量(liang)(liang)、標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，以便選(xuan)購與之(zhi)適配(pei)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。 3、目(mu)前(qian)手機(ji)(ji)使用(yong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)幾(ji)乎都是只(zhi)有(you)一個單體電(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)、標(biao)(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)(wei)3.6V、額定(ding)容(rong)量(liang)(liang)為(wei)(wei)500mAh～1000mAh的(de)(de)鋰離(li)(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。鋰離(li)(li)子(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)對充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)和充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)要(yao)求非(fei)常高；充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)過(guo)(guo)大(da)(da)或充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)過(guo)(guo)高，會引起電(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)內部化學(xue)反應(ying)(ying)巨(ju)變，使得(de)內部溫(wen)度升(sheng)高，導(dao)致電(dian)(dian)(dian)(dian)(dian)(dian)極、隔(ge)膜材料損壞(huai)或電(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)膨脹爆(bao)炸。雖然，一般(ban)手機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)內部裝有(you)具有(you)過(guo)(guo)充(chong)、過(guo)(guo)放、過(guo)(guo)流(liu)(liu)保護功能(neng)的(de)(de)保護器(qi)(qi)。但為(wei)(wei)了安全、為(wei)(wei)了達(da)到(dao)較好的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)效果，應(ying)(ying)選(xuan)購最(zui)大(da)(da)輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)(wei)4.2V～4.5V、最(zui)大(da)(da)輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)為(wei)(wei)600mA～700mA的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。

    規范的充電器產品(pin)都應標(biao)明其(qi)使用(yong)范圍、輸(shu)出(chu)(chu)電(dian)壓和輸(shu)出(chu)(chu)電(dian)流等(deng)技術參數。有條(tiao)件(jian)的話，選購時可用(yong)萬用(yong)表的適當(dang)測量檔測量充電(dian)器的輸(shu)出(chu)(chu)空載電(dian)壓和輸(shu)出(chu)(chu)短路電(dian)流，判(pan)斷其(qi)實際數據是否(fou)與所標(biao)技術參數一致。 另外，建議應到信(xin)譽較好(hao)、規模較大的電(dian)訊電(dian)器專賣(mai)店選購。
