【手機伴侶(lv)充(chong)電(dian)寶】充(chong)電(dian)寶怎么充(chong)電(dian) 充(chong)電(dian)寶充(chong)電(dian)時間(jian)多久合(he)適

說到移動電源，我們不得不引入充(chong)(chong)(chong)(chong)電(dian)寶充(chong)(chong)(chong)(chong)電(dian)時(shi)(shi)(shi)間(jian)這個(ge)概念。這里(li)并不是(shi)指移(yi)動(dong)(dong)(dong)電(dian)源(yuan)對(dui)手機設備的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)時(shi)(shi)(shi)間(jian)，而是(shi)電(dian)源(yuan)給移(yi)動(dong)(dong)(dong)電(dian)源(yuan)的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)時(shi)(shi)(shi)間(jian)。這里(li)有一個(ge)算(suan)法，用移(yi)動(dong)(dong)(dong)電(dian)源(yuan)的(de)(de)(de)(de)容(rong)(rong)量(liang)除以(yi)充(chong)(chong)(chong)(chong)電(dian)電(dian)流，再除以(yi)一個(ge)0.8的(de)(de)(de)(de)做(zuo)功轉換系數，得出的(de)(de)(de)(de)時(shi)(shi)(shi)間(jian)基本就(jiu)是(shi)充(chong)(chong)(chong)(chong)電(dian)時(shi)(shi)(shi)間(jian)了。舉例(li)來說(shuo)，一個(ge)容(rong)(rong)量(liang)為5000毫安(an)的(de)(de)(de)(de)移(yi)動(dong)(dong)(dong)電(dian)源(yuan)，用1A的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)器進行充(chong)(chong)(chong)(chong)電(dian)，根據上面(mian)的(de)(de)(de)(de)算(suan)法，大概6個(ge)多(duo)小時(shi)(shi)(shi)就(jiu)可以(yi)充(chong)(chong)(chong)(chong)滿。

在(zai)選擇移動電源時，應當注意(yi)充(chong)電時間，即便(bian)是晚(wan)上充(chong)電白(bai)天使用的(de)(de)話，如(ru)果超過8個小(xiao)時，這很難與(yu)現代人的(de)(de)作息習慣相(xiang)吻合：早上起來(lai)發(fa)現昨晚(wan)插上的(de)(de)移動電源竟然(ran)還在(zai)充(chong)電，這是讓人非常不爽的(de)(de)一件(jian)事(shi)情。

充電寶怎么充電

如果是普(pu)通(tong)充手(shou)機之類的(de)(de)數碼(ma)產品(pin)，那么普(pu)通(tong)的(de)(de)1A電(dian)(dian)流(liu)輸出(chu)的(de)(de)移動電(dian)(dian)源(yuan)已經完全夠用了，但如果要是充iPad的(de)(de)話就需要2A以(yi)上的(de)(de)電(dian)(dian)流(liu)的(de)(de)，否則即便(bian)是連接上也會顯示該設(she)備(bei)不(bu)在充電(dian)(dian)，用戶可以(yi)根據自(zi)己的(de)(de)事情情況(kuang)加以(yi)選擇(ze)。

1A輸出電流：主流的(de)(de)(de)移動電源(yuan)一(yi)般為一(yi)個(ge)(ge)USB充電插口，而(er)5000毫安(an)甚至(zhi)(zhi)以(yi)上即便(bian)的(de)(de)(de)產品(pin)會(hui)配備兩(liang)個(ge)(ge)甚至(zhi)(zhi)更多(duo)個(ge)(ge)USB接口。這樣做最大的(de)(de)(de)好處就是(shi)可(ke)以(yi)同時給多(duo)臺設(she)備充電，從而(er)達到節(jie)省(sheng)時間的(de)(de)(de)目的(de)(de)(de)。不(bu)過，這樣做也會(hui)有弊端，比如(ru)多(duo)口設(she)備同時工作的(de)(de)(de)時候，每個(ge)(ge)接口不(bu)可(ke)能達到宣(xuan)稱的(de)(de)(de)電流輸出指標(biao)，下(xia)降是(shi)必(bi)須的(de)(de)(de)。這就對移動電源(yuan)本身(shen)的(de)(de)(de)電路和品(pin)質有著較高的(de)(de)(de)要(yao)求，用戶在(zai)購買時需要(yao)注(zhu)意挑(tiao)選。

可調(diao)輸(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)：需(xu)要注意的(de)(de)(de)(de)是，以上所(suo)(suo)(suo)提到(dao)的(de)(de)(de)(de)USB充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)口(kou)輸(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)基本都(dou)是1A，這(zhe)就(jiu)意味著(zhu)這(zhe)樣(yang)(yang)的(de)(de)(de)(de)移動電(dian)(dian)(dian)(dian)(dian)(dian)源是無法為iPad等(deng)大電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)產品(pin)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)，所(suo)(suo)(suo)以充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)可調(diao)的(de)(de)(de)(de)移動電(dian)(dian)(dian)(dian)(dian)(dian)源就(jiu)應(ying)運而生(sheng)。這(zhe)樣(yang)(yang)的(de)(de)(de)(de)移動電(dian)(dian)(dian)(dian)(dian)(dian)源一般標(biao)配多個(ge)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)輸(shu)(shu)出口(kou)，而每個(ge)輸(shu)(shu)出口(kou)的(de)(de)(de)(de)輸(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)會在明(ming)顯(xian)的(de)(de)(de)(de)位置加(jia)以標(biao)注，比如1A、2A等(deng)字樣(yang)(yang)，用戶可以根據自身的(de)(de)(de)(de)實(shi)際使用需(xu)求來(lai)選擇。另外，還有一種單口(kou)輸(shu)(shu)出、多種電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)可調(diao)的(de)(de)(de)(de)移動電(dian)(dian)(dian)(dian)(dian)(dian)源，由于此類產品(pin)價格高昂(ang)、體積龐大、重(zhong)量(liang)也難以接受，普通用戶在使用中(zhong)很難碰到(dao)，所(suo)(suo)(suo)以我們在此一筆帶過。

用不同電流輸出的插孔為同一臺手機充電的利弊

優點(dian)：鋰電(dian)池的充電(dian)截止閥值是(shi)以電(dian)壓來計算的，用不同電(dian)流輸(shu)出(chu)的插孔為同一臺手機(ji)充電(dian)，只會獲得更快的充電(dian)速度，對手機(ji)其(qi)它(ta)部(bu)分沒(mei)有影響，更不會損壞(huai)手機(ji)。

缺點：唯一不好的地方就是(shi)，大電(dian)(dian)流充(chong)電(dian)(dian)會帶(dai)來較(jiao)高(gao)的熱量，這(zhe)對(dui)于電(dian)(dian)子(zi)元件的保護、保養是(shi)沒有好處(chu)的，可能會加速電(dian)(dian)子(zi)元件的老化。如果用(yong)戶(hu)不是(shi)很有必要用(yong)大電(dian)(dian)流對(dui)手機(ji)進行充(chong)電(dian)(dian)的話，我(wo)們還是(shi)建議按照手機(ji)說明書上要求的額定(ding)電(dian)(dian)流充(chong)電(dian)(dian)，這(zhe)樣來的比(bi)較(jiao)穩妥。

充電寶給手機充電斷開的原因

很多(duo)網友(you)反映，購買到的充(chong)電寶給手(shou)機充(chong)電時，充(chong)一會(hui)兒就(jiu)斷開了，這(zhe)種情況，一般來說與移動電源的質量有關，主要有如下(xia)幾(ji)個因素：

1、充電寶輸出電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)不夠(gou)。這是根(gen)據充電(dian)(dian)(dian)(dian)原理決(jue)定的，必須是高電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)流向(xiang)低(di)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，手機一般是3.7V，移(yi)(yi)動(dong)電(dian)(dian)(dian)(dian)源鋰(li)電(dian)(dian)(dian)(dian)芯是3.7V，這樣就是平(ping)級的，因此移(yi)(yi)動(dong)電(dian)(dian)(dian)(dian)源在(zai)輸出電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)時(shi)，會進行升壓(ya)(ya)(ya)(ya)到5V，這樣就產生高電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)流向(xiang)低(di)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，進行充電(dian)(dian)(dian)(dian)。

2、充電(dian)(dian)寶輸出(chu)電(dian)(dian)流強度不(bu)(bu)夠(gou)。我們(men)在測(ce)試一些移(yi)動電(dian)(dian)源的時候，上(shang)面標(biao)稱有(you)800mAh放(fang)電(dian)(dian)，但是有(you)時根本(ben)不(bu)(bu)能以這(zhe)個規格進行放(fang)電(dian)(dian)，電(dian)(dian)流強度不(bu)(bu)夠(gou)時也(ye)會發生(sheng)這(zhe)種現象，這(zhe)個和電(dian)(dian)壓息息相關，最根本(ben)的還是鋰電(dian)(dian)芯質量(liang)不(bu)(bu)好所致。

3、與手機本身有關。可能手機電阻值過大(da)，其實這種(zhong)情況(kuang)的可能性(xing)非常(chang)少。只(zhi)是在此提及。

4、與移動電(dian)源的PCBA保(bao)護(hu)板(ban)有(you)關。在第1點提到(dao)，保(bao)護(hu)板(ban)要起到(dao)過流過充過放的功(gong)能，同時(shi)還有(you)一(yi)個MCU，這個就(jiu)是用來升壓，如果(guo)保(bao)護(hu)板(ban)質量不好，在電(dian)流穿過時(shi)就(jiu)不穩(wen)定，導至(zhi)PCBA怠工(gong)，然(ran)后導致充電(dian)寶無法充電(dian)，發生上述(shu)的情況。
