1，手機(ji)(ji)充(chong)電(dian)器(qi)主要用(yong)于(yu)給(gei)手機(ji)(ji)、平板電(dian)腦(nao)等(deng)與手機(ji)(ji)接口一樣的設備充(chong)電(dian)。首選手機(ji)(ji)原裝充(chong)電(dian)器(qi)，此外，正規廠家生(sheng)產的貼有CQC認證標志的充(chong)電(dian)器(qi)，有安全保證，可避(bi)免存(cun)在手機(ji)(ji)不兼容的問(wen)題，也值得選擇。

2，車(che)載充(chong)電(dian)器是(shi)指通過(guo)汽(qi)車(che)電(dian)瓶供電(dian)的(de)車(che)載配件(jian)。選購時要清楚(chu)自己汽(qi)車(che)點煙器的(de)輸出電(dian)壓(ya)(ya)，最好選12V-24V電(dian)壓(ya)(ya)輸入，適合所有(you)車(che)型；選有(you)過(guo)壓(ya)(ya)、過(guo)流(liu)、過(guo)熱、和短路(lu)保(bao)護功能的(de)車(che)載充(chong)電(dian)器，使用更安(an)全。

3，電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)(che)充(chong)電(dian)(dian)(dian)器多使(shi)用(yong)的(de)(de)是(shi)(shi)三段(duan)式充(chong)電(dian)(dian)(dian)器，可用(yong)于給電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)自行(xing)車(che)(che)、電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)摩(mo)的(de)(de)充(chong)電(dian)(dian)(dian)。首先選與電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)(che)品牌適配的(de)(de)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)(che)充(chong)電(dian)(dian)(dian)器；再是(shi)(shi)確定電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)(che)的(de)(de)電(dian)(dian)(dian)池電(dian)(dian)(dian)壓或是(shi)(shi)原充(chong)電(dian)(dian)(dian)器的(de)(de)輸出(chu)電(dian)(dian)(dian)壓；最后是(shi)(shi)確定電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)車(che)(che)電(dian)(dian)(dian)池的(de)(de)電(dian)(dian)(dian)池容量或者是(shi)(shi)原充(chong)電(dian)(dian)(dian)器的(de)(de)輸出(chu)電(dian)(dian)(dian)流。

4，電(dian)瓶(ping)充(chong)(chong)電(dian)器可(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)(de)電(dian)瓶(ping)充(chong)(chong)電(dian)。最好(hao)選選擇全自動(dong)的(de)(de)電(dian)瓶(ping)充(chong)(chong)電(dian)器，可(ke)自動(dong)識別電(dian)壓(ya)電(dian)力(li)，可(ke)更(geng)大(da)程度上(shang)保護(hu)電(dian)瓶(ping)；選有過熱、短(duan)路(lu)、抵壓(ya)、反(fan)接保護(hu)的(de)(de)電(dian)瓶(ping)充(chong)(chong)電(dian)器，延長(chang)使用(yong)壽命。

5，電(dian)(dian)腦充電(dian)(dian)器(qi)主要用(yong)于給筆記本(ben)電(dian)(dian)腦充電(dian)(dian)的(de)設(she)備。首先看是否(fou)與自(zi)己的(de)電(dian)(dian)腦相兼容，適配器(qi)的(de)接口與設(she)備是否(fou)完全匹(pi)配；輸出電(dian)(dian)壓必須與負(fu)載(zai)(zai)額定輸入電(dian)(dian)壓相同；電(dian)(dian)源適配器(qi)的(de)輸出電(dian)(dian)流應等于、大于負(fu)載(zai)(zai)電(dian)(dian)流。
