1，手機(ji)充(chong)電器(qi)主要用于給手機(ji)、平板電腦等(deng)與手機(ji)接口一樣(yang)的設(she)備(bei)充(chong)電。首選(xuan)手機(ji)原(yuan)裝充(chong)電器(qi)，此外，正規廠(chang)家生產(chan)的貼有(you)CQC認證標志(zhi)的充(chong)電器(qi)，有(you)安全保證，可避免存在手機(ji)不兼容的問題(ti)，也值得選(xuan)擇。

2，車(che)(che)載充電(dian)(dian)器(qi)是指通過(guo)(guo)汽車(che)(che)電(dian)(dian)瓶供(gong)電(dian)(dian)的車(che)(che)載配(pei)件(jian)。選購時(shi)要清(qing)楚自己汽車(che)(che)點煙器(qi)的輸出電(dian)(dian)壓(ya)，最好選12V-24V電(dian)(dian)壓(ya)輸入(ru)，適合所有(you)車(che)(che)型；選有(you)過(guo)(guo)壓(ya)、過(guo)(guo)流、過(guo)(guo)熱、和短路保護功能的車(che)(che)載充電(dian)(dian)器(qi)，使用更安全(quan)。

3，電(dian)(dian)動車(che)(che)充(chong)電(dian)(dian)器多使用(yong)的(de)是三段式(shi)充(chong)電(dian)(dian)器，可用(yong)于給電(dian)(dian)動自行(xing)車(che)(che)、電(dian)(dian)動摩的(de)充(chong)電(dian)(dian)。首先(xian)選與(yu)電(dian)(dian)動車(che)(che)品牌適(shi)配的(de)電(dian)(dian)動車(che)(che)充(chong)電(dian)(dian)器；再(zai)是確定電(dian)(dian)動車(che)(che)的(de)電(dian)(dian)池電(dian)(dian)壓或(huo)是原(yuan)充(chong)電(dian)(dian)器的(de)輸出(chu)電(dian)(dian)壓；最(zui)后是確定電(dian)(dian)動車(che)(che)電(dian)(dian)池的(de)電(dian)(dian)池容量或(huo)者是原(yuan)充(chong)電(dian)(dian)器的(de)輸出(chu)電(dian)(dian)流。

4，電(dian)(dian)瓶(ping)(ping)充(chong)電(dian)(dian)器(qi)可用于給轎車、摩托(tuo)車、小型貨車等汽車的(de)電(dian)(dian)瓶(ping)(ping)充(chong)電(dian)(dian)。最好選(xuan)(xuan)選(xuan)(xuan)擇全自動的(de)電(dian)(dian)瓶(ping)(ping)充(chong)電(dian)(dian)器(qi)，可自動識別電(dian)(dian)壓電(dian)(dian)力(li)，可更大(da)程度上(shang)保護電(dian)(dian)瓶(ping)(ping)；選(xuan)(xuan)有過(guo)熱、短路、抵壓、反接(jie)保護的(de)電(dian)(dian)瓶(ping)(ping)充(chong)電(dian)(dian)器(qi)，延長使用壽命。

5，電(dian)腦(nao)充電(dian)器(qi)主要用于給筆記本電(dian)腦(nao)充電(dian)的設備。首(shou)先(xian)看(kan)是(shi)否與(yu)自己的電(dian)腦(nao)相兼容，適配器(qi)的接(jie)口與(yu)設備是(shi)否完(wan)全匹配；輸(shu)出電(dian)壓必(bi)須與(yu)負載(zai)額(e)定(ding)輸(shu)入(ru)電(dian)壓相同；電(dian)源適配器(qi)的輸(shu)出電(dian)流(liu)應等于、大于負載(zai)電(dian)流(liu)。
