1，手(shou)(shou)機(ji)充(chong)(chong)電(dian)(dian)器(qi)主要用于給手(shou)(shou)機(ji)、平板電(dian)(dian)腦等(deng)與手(shou)(shou)機(ji)接(jie)口一樣的設備充(chong)(chong)電(dian)(dian)。首選手(shou)(shou)機(ji)原(yuan)裝充(chong)(chong)電(dian)(dian)器(qi)，此外，正規廠家(jia)生產的貼有CQC認(ren)證(zheng)標志的充(chong)(chong)電(dian)(dian)器(qi)，有安全保證(zheng)，可避免存在手(shou)(shou)機(ji)不兼(jian)容的問題(ti)，也值得選擇。

2，車載(zai)充(chong)電(dian)(dian)器(qi)是指通過(guo)汽車電(dian)(dian)瓶供電(dian)(dian)的車載(zai)配件(jian)。選購時要清楚自己(ji)汽車點煙器(qi)的輸(shu)出(chu)電(dian)(dian)壓，最好選12V-24V電(dian)(dian)壓輸(shu)入，適合所有車型(xing)；選有過(guo)壓、過(guo)流、過(guo)熱、和(he)短路保(bao)護功能的車載(zai)充(chong)電(dian)(dian)器(qi)，使(shi)用更安全(quan)。

3，電(dian)(dian)(dian)動車(che)(che)充電(dian)(dian)(dian)器(qi)(qi)多(duo)使(shi)用(yong)的(de)(de)(de)是(shi)三(san)段式充電(dian)(dian)(dian)器(qi)(qi)，可用(yong)于給電(dian)(dian)(dian)動自行車(che)(che)、電(dian)(dian)(dian)動摩的(de)(de)(de)充電(dian)(dian)(dian)。首先選(xuan)與電(dian)(dian)(dian)動車(che)(che)品牌(pai)適配(pei)的(de)(de)(de)電(dian)(dian)(dian)動車(che)(che)充電(dian)(dian)(dian)器(qi)(qi)；再是(shi)確定電(dian)(dian)(dian)動車(che)(che)的(de)(de)(de)電(dian)(dian)(dian)池電(dian)(dian)(dian)壓或(huo)是(shi)原充電(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)輸出電(dian)(dian)(dian)壓；最(zui)后是(shi)確定電(dian)(dian)(dian)動車(che)(che)電(dian)(dian)(dian)池的(de)(de)(de)電(dian)(dian)(dian)池容量或(huo)者是(shi)原充電(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)輸出電(dian)(dian)(dian)流(liu)。

4，電(dian)瓶充電(dian)器(qi)可(ke)用(yong)于給轎車(che)、摩托車(che)、小(xiao)型貨車(che)等汽(qi)車(che)的(de)電(dian)瓶充電(dian)。最(zui)好選選擇全自動(dong)的(de)電(dian)瓶充電(dian)器(qi)，可(ke)自動(dong)識別電(dian)壓(ya)電(dian)力，可(ke)更大程度上保護電(dian)瓶；選有(you)過熱、短路、抵壓(ya)、反接(jie)保護的(de)電(dian)瓶充電(dian)器(qi)，延長使用(yong)壽(shou)命。

5，電(dian)(dian)(dian)腦(nao)充(chong)(chong)電(dian)(dian)(dian)器(qi)主要(yao)用于(yu)給(gei)筆(bi)記(ji)本(ben)電(dian)(dian)(dian)腦(nao)充(chong)(chong)電(dian)(dian)(dian)的設(she)備。首先看是否與自(zi)己的電(dian)(dian)(dian)腦(nao)相(xiang)(xiang)兼容，適配(pei)器(qi)的接口與設(she)備是否完全匹(pi)配(pei)；輸出(chu)電(dian)(dian)(dian)壓(ya)必(bi)須(xu)與負(fu)載額定輸入電(dian)(dian)(dian)壓(ya)相(xiang)(xiang)同；電(dian)(dian)(dian)源適配(pei)器(qi)的輸出(chu)電(dian)(dian)(dian)流(liu)應等(deng)于(yu)、大(da)于(yu)負(fu)載電(dian)(dian)(dian)流(liu)。
