1，手(shou)機充(chong)電器主要用于給手(shou)機、平板電腦等與手(shou)機接(jie)口(kou)一樣的設備充(chong)電。首選(xuan)手(shou)機原裝充(chong)電器，此外，正(zheng)規(gui)廠家生產的貼有CQC認證標(biao)志的充(chong)電器，有安全(quan)保證，可避免(mian)存(cun)在(zai)手(shou)機不兼容的問(wen)題，也值得選(xuan)擇。

2，車載(zai)(zai)充電器是(shi)指通過汽(qi)車電瓶供電的車載(zai)(zai)配件。選購(gou)時要清(qing)楚自己汽(qi)車點(dian)煙器的輸出電壓(ya)，最好選12V-24V電壓(ya)輸入(ru)，適合所(suo)有車型；選有過壓(ya)、過流、過熱、和(he)短路(lu)保護功能的車載(zai)(zai)充電器，使用更安全。

3，電(dian)(dian)(dian)(dian)動(dong)車充電(dian)(dian)(dian)(dian)器(qi)多(duo)使(shi)用的(de)(de)是(shi)三段式充電(dian)(dian)(dian)(dian)器(qi)，可用于給電(dian)(dian)(dian)(dian)動(dong)自行(xing)車、電(dian)(dian)(dian)(dian)動(dong)摩的(de)(de)充電(dian)(dian)(dian)(dian)。首先(xian)選(xuan)與電(dian)(dian)(dian)(dian)動(dong)車品(pin)牌適配的(de)(de)電(dian)(dian)(dian)(dian)動(dong)車充電(dian)(dian)(dian)(dian)器(qi)；再是(shi)確(que)定電(dian)(dian)(dian)(dian)動(dong)車的(de)(de)電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓(ya)或是(shi)原(yuan)(yuan)充電(dian)(dian)(dian)(dian)器(qi)的(de)(de)輸出電(dian)(dian)(dian)(dian)壓(ya)；最后是(shi)確(que)定電(dian)(dian)(dian)(dian)動(dong)車電(dian)(dian)(dian)(dian)池的(de)(de)電(dian)(dian)(dian)(dian)池容(rong)量或者是(shi)原(yuan)(yuan)充電(dian)(dian)(dian)(dian)器(qi)的(de)(de)輸出電(dian)(dian)(dian)(dian)流。

4，電(dian)(dian)(dian)瓶(ping)充(chong)電(dian)(dian)(dian)器(qi)可(ke)用于給轎車、摩托(tuo)車、小型貨車等汽車的(de)電(dian)(dian)(dian)瓶(ping)充(chong)電(dian)(dian)(dian)。最好選(xuan)選(xuan)擇全自(zi)動的(de)電(dian)(dian)(dian)瓶(ping)充(chong)電(dian)(dian)(dian)器(qi)，可(ke)自(zi)動識別電(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)力，可(ke)更(geng)大程度上保護(hu)電(dian)(dian)(dian)瓶(ping)；選(xuan)有(you)過(guo)熱、短路、抵壓(ya)、反接(jie)保護(hu)的(de)電(dian)(dian)(dian)瓶(ping)充(chong)電(dian)(dian)(dian)器(qi)，延長使用壽命。

5，電腦(nao)充(chong)電器主要(yao)用于(yu)給筆記本電腦(nao)充(chong)電的(de)設(she)備。首先看(kan)是否與(yu)(yu)自己的(de)電腦(nao)相兼容，適(shi)配(pei)器的(de)接口(kou)與(yu)(yu)設(she)備是否完全匹配(pei)；輸出(chu)電壓必須與(yu)(yu)負(fu)(fu)載(zai)額(e)定(ding)輸入電壓相同；電源(yuan)適(shi)配(pei)器的(de)輸出(chu)電流應等于(yu)、大于(yu)負(fu)(fu)載(zai)電流。
