一、車載手機充電器多少安的充電快

車(che)(che)載(zai)(zai)充(chong)(chong)電(dian)(dian)(dian)器(qi)深受(shou)車(che)(che)主(zhu)的(de)青睞，不過也(ye)有(you)(you)一(yi)部分車(che)(che)主(zhu)抱怨車(che)(che)載(zai)(zai)充(chong)(chong)電(dian)(dian)(dian)器(qi)的(de)充(chong)(chong)電(dian)(dian)(dian)效率慢(man)，一(yi)般情(qing)況(kuang)下，車(che)(che)載(zai)(zai)充(chong)(chong)電(dian)(dian)(dian)器(qi)效率低的(de)原因有(you)(you)兩種(zhong)，一(yi)種(zhong)是(shi)(shi)車(che)(che)載(zai)(zai)充(chong)(chong)電(dian)(dian)(dian)器(qi)本身質量有(you)(you)問題，遇(yu)上這(zhe)種(zhong)情(qing)況(kuang)，我們(men)購買一(yi)個好一(yi)點的(de)車(che)(che)載(zai)(zai)充(chong)(chong)電(dian)(dian)(dian)器(qi)就可以解決；另一(yi)種(zhong)是(shi)(shi)車(che)(che)載(zai)(zai)充(chong)(chong)電(dian)(dian)(dian)器(qi)的(de)功(gong)率較(jiao)低，一(yi)般功(gong)率較(jiao)低的(de)車(che)(che)載(zai)(zai)充(chong)(chong)電(dian)(dian)(dian)器(qi)充(chong)(chong)電(dian)(dian)(dian)速度會(hui)慢(man)，尤其是(shi)(shi)在(zai)一(yi)些車(che)(che)載(zai)(zai)充(chong)(chong)電(dian)(dian)(dian)器(qi)支(zhi)持(chi)快充(chong)(chong)功(gong)能后(hou)，對比起來就顯得更慢(man)了(le)，那么車(che)(che)載(zai)(zai)充(chong)(chong)電(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)流多大好呢？

車載(zai)充(chong)電(dian)(dian)器(qi)(qi)均(jun)適用于12V、24V的(de)車載(zai)點煙器(qi)(qi)接口，而其輸(shu)出功(gong)率則(ze)根(gen)據車載(zai)充(chong)電(dian)(dian)器(qi)(qi)產品(pin)不(bu)同有一(yi)定差異，一(yi)般(ban)為(wei)5V/1A，功(gong)率大概(gai)為(wei)5W左右；部分支持快充(chong)功(gong)能(neng)的(de)車載(zai)充(chong)電(dian)(dian)器(qi)(qi)能(neng)達到5V/2A（10W），甚至(zhi)是9V/2A（18W）。

考(kao)慮到車(che)載(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)電(dian)(dian)(dian)(dian)(dian)的(de)(de)安全(quan)問題(ti)，車(che)載(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)和電(dian)(dian)(dian)(dian)(dian)壓也不(bu)宜(yi)過(guo)大，另(ling)外，一定要注意(yi)選擇具(ju)有過(guo)載(zai)保護功能(neng)的(de)(de)產(chan)品，以(yi)免輸出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)過(guo)大會(hui)縮短(duan)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)元件壽命，或者因為溫度過(guo)高導致損壞(huai)甚至自(zi)燃(ran)。還要注意(yi)的(de)(de)是，市面上的(de)(de)車(che)載(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)輸入電(dian)(dian)(dian)(dian)(dian)壓基本都是12V—24V，輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓為5V，而輸出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)則(ze)在1A~4A左右，但是部分“三無”或者“山寨”產(chan)品普遍有充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)虛標(biao)的(de)(de)現象，這會(hui)影(ying)響(xiang)到手機(ji)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)效率，因此(ci)要選購(gou)正規產(chan)品。

二、車載充電器電流小怎么辦

車載充電(dian)(dian)器(qi)充電(dian)(dian)慢，如(ru)果又剛好在使用手(shou)機導航的話，不一會兒就(jiu)會發(fa)現手(shou)機電(dian)(dian)量不增反降，甚至手(shou)機還特別燙，這一般(ban)是因為車載充電(dian)(dian)器(qi)電(dian)(dian)流小導致的，那么(me)車充電(dian)(dian)流小怎么(me)辦呢？遇上這種(zhong)情況，我們應該：

1、直接用車上自帶的USB接口充電

車內的USB接口(kou)是為(wei)了音頻數(shu)據傳(chuan)輸(shu)用的，不(bu)適合給手(shou)機充電，其(qi)輸(shu)出電流(liu)(liu)也(ye)只有(you)5V/0.5A，不(bu)過許(xu)多車型也(ye)有(you)符合手(shou)機等(deng)移動設備使用的USB接口(kou)，通常設置(zhi)在扶手(shou)箱、后排出風口(kou)下方，帶有(you)電流(liu)(liu)標志。

2、使用車充時選擇正確的接口

車載充電器一(yi)般有單口(kou)(kou)(kou)、雙口(kou)(kou)(kou)、多口(kou)(kou)(kou)等類型(xing)，其(qi)中雙口(kou)(kou)(kou)比較常用，爽(shuang)口(kou)(kou)(kou)一(yi)般是兩(liang)種規格(ge)，一(yi)個是5V/1A，另一(yi)個通(tong)常是5V/2.1A，手機(ji)適(shi)合(he)1A的接口(kou)(kou)(kou)，平板適(shi)合(he)2.1A的接口(kou)(kou)(kou)，如果接錯了(le)可能會導(dao)致充電慢、手機(ji)發燙等，長此以往還會損壞電池，因此要注意選(xuan)擇(ze)正確的接口(kou)(kou)(kou)。
