1，手機(ji)充(chong)(chong)電器(qi)主要用于給手機(ji)、平板(ban)電腦等與手機(ji)接口一樣的(de)設備充(chong)(chong)電。首選手機(ji)原裝充(chong)(chong)電器(qi)，此外，正規廠家生產的(de)貼有CQC認證(zheng)(zheng)標志的(de)充(chong)(chong)電器(qi)，有安全保證(zheng)(zheng)，可避(bi)免存在手機(ji)不兼容的(de)問題，也值得選擇。

2，車(che)載(zai)(zai)充電(dian)器是指通過(guo)汽車(che)電(dian)瓶供(gong)電(dian)的(de)車(che)載(zai)(zai)配(pei)件。選購時要清楚自己汽車(che)點煙器的(de)輸出電(dian)壓(ya)，最好選12V-24V電(dian)壓(ya)輸入，適合所有車(che)型(xing)；選有過(guo)壓(ya)、過(guo)流、過(guo)熱、和(he)短路保護(hu)功能的(de)車(che)載(zai)(zai)充電(dian)器，使用更安(an)全。

3，電(dian)(dian)(dian)動(dong)車(che)充電(dian)(dian)(dian)器(qi)多(duo)使用(yong)的是三段式充電(dian)(dian)(dian)器(qi)，可(ke)用(yong)于給電(dian)(dian)(dian)動(dong)自行車(che)、電(dian)(dian)(dian)動(dong)摩的充電(dian)(dian)(dian)。首(shou)先選與電(dian)(dian)(dian)動(dong)車(che)品牌適配的電(dian)(dian)(dian)動(dong)車(che)充電(dian)(dian)(dian)器(qi)；再(zai)是確定電(dian)(dian)(dian)動(dong)車(che)的電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓或(huo)(huo)是原充電(dian)(dian)(dian)器(qi)的輸出(chu)電(dian)(dian)(dian)壓；最后是確定電(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)池(chi)(chi)的電(dian)(dian)(dian)池(chi)(chi)容量或(huo)(huo)者是原充電(dian)(dian)(dian)器(qi)的輸出(chu)電(dian)(dian)(dian)流。

4，電(dian)(dian)(dian)瓶(ping)(ping)(ping)充電(dian)(dian)(dian)器可(ke)用于給轎車、摩托車、小型貨車等汽車的電(dian)(dian)(dian)瓶(ping)(ping)(ping)充電(dian)(dian)(dian)。最好(hao)選(xuan)選(xuan)擇全自(zi)(zi)動的電(dian)(dian)(dian)瓶(ping)(ping)(ping)充電(dian)(dian)(dian)器，可(ke)自(zi)(zi)動識別電(dian)(dian)(dian)壓電(dian)(dian)(dian)力，可(ke)更大程度(du)上保護(hu)電(dian)(dian)(dian)瓶(ping)(ping)(ping)；選(xuan)有(you)過熱(re)、短路、抵(di)壓、反接保護(hu)的電(dian)(dian)(dian)瓶(ping)(ping)(ping)充電(dian)(dian)(dian)器，延長使用壽(shou)命(ming)。

5，電(dian)(dian)(dian)腦(nao)充(chong)電(dian)(dian)(dian)器(qi)主要用(yong)于給筆記本(ben)電(dian)(dian)(dian)腦(nao)充(chong)電(dian)(dian)(dian)的(de)(de)(de)設(she)備。首先(xian)看(kan)是(shi)(shi)否與(yu)自(zi)己(ji)的(de)(de)(de)電(dian)(dian)(dian)腦(nao)相兼(jian)容，適配器(qi)的(de)(de)(de)接口與(yu)設(she)備是(shi)(shi)否完全匹配；輸出(chu)(chu)電(dian)(dian)(dian)壓(ya)必須與(yu)負(fu)載(zai)額定輸入電(dian)(dian)(dian)壓(ya)相同(tong)；電(dian)(dian)(dian)源適配器(qi)的(de)(de)(de)輸出(chu)(chu)電(dian)(dian)(dian)流應等于、大于負(fu)載(zai)電(dian)(dian)(dian)流。
