一、車載手機充電器多少安的充電快
車(che)(che)載(zai)(zai)(zai)充(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)(qi)深受車(che)(che)主的(de)(de)青睞,不過(guo)也有一(yi)部分車(che)(che)主抱(bao)怨車(che)(che)載(zai)(zai)(zai)充(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)(qi)的(de)(de)充(chong)(chong)(chong)(chong)(chong)電(dian)效率(lv)(lv)慢(man),一(yi)般情(qing)況(kuang)下,車(che)(che)載(zai)(zai)(zai)充(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)(qi)效率(lv)(lv)低的(de)(de)原因有兩種,一(yi)種是車(che)(che)載(zai)(zai)(zai)充(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)(qi)本身質量有問(wen)題,遇(yu)上這種情(qing)況(kuang),我們購買一(yi)個好一(yi)點(dian)的(de)(de)車(che)(che)載(zai)(zai)(zai)充(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)(qi)就可(ke)以解決(jue);另一(yi)種是車(che)(che)載(zai)(zai)(zai)充(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)(qi)的(de)(de)功率(lv)(lv)較低,一(yi)般功率(lv)(lv)較低的(de)(de)車(che)(che)載(zai)(zai)(zai)充(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)(qi)充(chong)(chong)(chong)(chong)(chong)電(dian)速(su)度會慢(man),尤其是在(zai)一(yi)些車(che)(che)載(zai)(zai)(zai)充(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)(qi)支持快(kuai)充(chong)(chong)(chong)(chong)(chong)功能后,對比起來就顯得(de)更慢(man)了,那么車(che)(che)載(zai)(zai)(zai)充(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)(qi)電(dian)流多大(da)好呢(ni)?
車載充(chong)電器(qi)均適用(yong)于12V、24V的車載點煙器(qi)接口,而(er)其輸出功率則(ze)根(gen)據車載充(chong)電器(qi)產品(pin)不同有一定差異,一般(ban)為5V/1A,功率大概為5W左右;部分支持快充(chong)功能的車載充(chong)電器(qi)能達到5V/2A(10W),甚至是9V/2A(18W)。
考(kao)慮到車載充(chong)電(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)的(de)安全問題,車載充(chong)電(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)流(liu)(liu)(liu)和電(dian)(dian)(dian)壓(ya)也不(bu)宜(yi)過(guo)大,另(ling)外,一定要(yao)注(zhu)意(yi)選(xuan)擇具有過(guo)載保護功(gong)能的(de)產(chan)品(pin),以(yi)免輸(shu)出(chu)電(dian)(dian)(dian)流(liu)(liu)(liu)過(guo)大會縮短充(chong)電(dian)(dian)(dian)器(qi)元件壽命,或者因為溫度(du)過(guo)高導致損壞(huai)甚至自燃。還要(yao)注(zhu)意(yi)的(de)是(shi),市面上的(de)車載充(chong)電(dian)(dian)(dian)器(qi)的(de)輸(shu)入(ru)電(dian)(dian)(dian)壓(ya)基本都是(shi)12V—24V,輸(shu)出(chu)電(dian)(dian)(dian)壓(ya)為5V,而輸(shu)出(chu)電(dian)(dian)(dian)流(liu)(liu)(liu)則(ze)在1A~4A左右,但(dan)是(shi)部分“三無”或者“山寨”產(chan)品(pin)普遍有充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)(liu)虛標(biao)的(de)現象,這會影(ying)響到手機的(de)充(chong)電(dian)(dian)(dian)效率,因此要(yao)選(xuan)購正規產(chan)品(pin)。
二、車載充電器電流小怎么辦
車載充電(dian)器充電(dian)慢,如(ru)果又剛好在使用手機導航(hang)的(de)話,不一(yi)會(hui)兒就會(hui)發現手機電(dian)量不增反(fan)降,甚至手機還特別燙,這(zhe)一(yi)般是(shi)因為車載充電(dian)器電(dian)流小(xiao)導致(zhi)的(de),那么車充電(dian)流小(xiao)怎么辦(ban)呢?遇上這(zhe)種情(qing)況(kuang),我們應該:
1、直接用車上自帶的USB接口充電
車(che)內的USB接口是為了(le)音(yin)頻數據傳輸用(yong)的,不適合(he)給手機充電,其(qi)輸出(chu)電流也(ye)只有5V/0.5A,不過(guo)許多車(che)型也(ye)有符合(he)手機等移(yi)動設備(bei)使用(yong)的USB接口,通常設置在扶手箱、后排(pai)出(chu)風口下方,帶有電流標志。
2、使用車充時選擇正確的接口
車載充電器一(yi)般(ban)有(you)單口(kou)(kou)(kou)(kou)(kou)、雙(shuang)(shuang)口(kou)(kou)(kou)(kou)(kou)、多口(kou)(kou)(kou)(kou)(kou)等(deng)類(lei)型,其(qi)中雙(shuang)(shuang)口(kou)(kou)(kou)(kou)(kou)比(bi)較(jiao)常用(yong),爽口(kou)(kou)(kou)(kou)(kou)一(yi)般(ban)是兩(liang)種規格,一(yi)個是5V/1A,另(ling)一(yi)個通(tong)常是5V/2.1A,手機(ji)適(shi)合1A的(de)接(jie)口(kou)(kou)(kou)(kou)(kou),平板適(shi)合2.1A的(de)接(jie)口(kou)(kou)(kou)(kou)(kou),如果接(jie)錯了可能會導致充電慢、手機(ji)發(fa)燙等(deng),長(chang)此以往還會損(sun)壞電池,因此要注意選擇(ze)正確的(de)接(jie)口(kou)(kou)(kou)(kou)(kou)。
