1，手(shou)(shou)機(ji)充(chong)(chong)電(dian)器(qi)主要(yao)用于(yu)給手(shou)(shou)機(ji)、平板電(dian)腦等與手(shou)(shou)機(ji)接口一樣的設備充(chong)(chong)電(dian)。首選手(shou)(shou)機(ji)原裝充(chong)(chong)電(dian)器(qi)，此外，正規廠(chang)家(jia)生產的貼有CQC認證(zheng)標志(zhi)的充(chong)(chong)電(dian)器(qi)，有安全(quan)保(bao)證(zheng)，可避免存在手(shou)(shou)機(ji)不兼容(rong)的問題，也值得選擇。

2，車(che)載充(chong)電(dian)器是指(zhi)通過(guo)(guo)汽車(che)電(dian)瓶供電(dian)的車(che)載配件。選購時要清楚自(zi)己汽車(che)點煙(yan)器的輸出電(dian)壓，最好選12V-24V電(dian)壓輸入(ru)，適合所有車(che)型；選有過(guo)(guo)壓、過(guo)(guo)流、過(guo)(guo)熱、和(he)短路保護(hu)功能的車(che)載充(chong)電(dian)器，使用更安全。

3，電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)多使用的(de)(de)(de)是三段式充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)，可用于給電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)自行車(che)、電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)摩的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。首先選與電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)品牌(pai)適配(pei)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)；再(zai)是確定電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓或是原(yuan)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓；最(zui)后是確定電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車(che)電(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池容(rong)量或者(zhe)是原(yuan)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)輸出(chu)電(dian)(dian)(dian)(dian)(dian)流。

4，電(dian)(dian)瓶(ping)(ping)充電(dian)(dian)器(qi)可(ke)(ke)用(yong)于給轎車(che)(che)、摩托車(che)(che)、小型貨車(che)(che)等汽車(che)(che)的(de)電(dian)(dian)瓶(ping)(ping)充電(dian)(dian)。最(zui)好選(xuan)選(xuan)擇全自(zi)動的(de)電(dian)(dian)瓶(ping)(ping)充電(dian)(dian)器(qi)，可(ke)(ke)自(zi)動識別電(dian)(dian)壓電(dian)(dian)力，可(ke)(ke)更大(da)程度上保護(hu)電(dian)(dian)瓶(ping)(ping)；選(xuan)有過(guo)熱(re)、短(duan)路、抵壓、反接保護(hu)的(de)電(dian)(dian)瓶(ping)(ping)充電(dian)(dian)器(qi)，延長(chang)使用(yong)壽命。

5，電(dian)腦充(chong)電(dian)器主要用于給(gei)筆記本電(dian)腦充(chong)電(dian)的(de)設(she)(she)備。首先(xian)看是否(fou)與(yu)自(zi)己的(de)電(dian)腦相(xiang)(xiang)兼(jian)容，適配器的(de)接口與(yu)設(she)(she)備是否(fou)完全匹(pi)配；輸(shu)出電(dian)壓必須與(yu)負(fu)載(zai)額定輸(shu)入(ru)電(dian)壓相(xiang)(xiang)同；電(dian)源適配器的(de)輸(shu)出電(dian)流(liu)應等(deng)于、大于負(fu)載(zai)電(dian)流(liu)。
