【手(shou)機伴(ban)侶充電(dian)(dian)(dian)寶(bao)(bao)】充電(dian)(dian)(dian)寶(bao)(bao)怎么充電(dian)(dian)(dian) 充電(dian)(dian)(dian)寶(bao)(bao)充電(dian)(dian)(dian)時間多久合適(shi)

說到移動電源，我們(men)不得不引(yin)入充(chong)(chong)電(dian)(dian)寶充(chong)(chong)電(dian)(dian)時間這個概(gai)念。這里并不是(shi)(shi)指(zhi)移(yi)(yi)(yi)動(dong)(dong)電(dian)(dian)源對手機設備的(de)充(chong)(chong)電(dian)(dian)時間，而是(shi)(shi)電(dian)(dian)源給移(yi)(yi)(yi)動(dong)(dong)電(dian)(dian)源的(de)充(chong)(chong)電(dian)(dian)時間。這里有一個算法(fa)(fa)，用(yong)移(yi)(yi)(yi)動(dong)(dong)電(dian)(dian)源的(de)容量除以(yi)(yi)充(chong)(chong)電(dian)(dian)電(dian)(dian)流，再(zai)除以(yi)(yi)一個0.8的(de)做(zuo)功轉換系數，得出的(de)時間基本就是(shi)(shi)充(chong)(chong)電(dian)(dian)時間了(le)。舉例來(lai)說，一個容量為5000毫(hao)安的(de)移(yi)(yi)(yi)動(dong)(dong)電(dian)(dian)源，用(yong)1A的(de)充(chong)(chong)電(dian)(dian)器進行充(chong)(chong)電(dian)(dian)，根(gen)據上面(mian)的(de)算法(fa)(fa)，大概(gai)6個多小時就可以(yi)(yi)充(chong)(chong)滿(man)。

在選擇(ze)移(yi)動電(dian)源時，應當注意充電(dian)時間(jian)，即便是(shi)晚(wan)上充電(dian)白(bai)天使(shi)用的話，如果(guo)超過8個小時，這很難與現代人的作息習慣相吻合：早上起來發(fa)現昨晚(wan)插上的移(yi)動電(dian)源竟然(ran)還在充電(dian)，這是(shi)讓人非(fei)常不爽的一件事情。

充電寶怎么充電

如果是普(pu)通充(chong)手機(ji)之類的(de)(de)(de)數(shu)碼產品，那么普(pu)通的(de)(de)(de)1A電(dian)流(liu)輸出的(de)(de)(de)移動電(dian)源已經完(wan)全夠用了，但如果要是充(chong)iPad的(de)(de)(de)話就需(xu)要2A以(yi)上的(de)(de)(de)電(dian)流(liu)的(de)(de)(de)，否則即便(bian)是連接上也會(hui)顯示該設備不在充(chong)電(dian)，用戶(hu)可(ke)以(yi)根據自己的(de)(de)(de)事情情況加以(yi)選擇。

1A輸出(chu)電(dian)(dian)(dian)流(liu)：主(zhu)流(liu)的移動(dong)電(dian)(dian)(dian)源一般(ban)為(wei)一個(ge)USB充(chong)(chong)電(dian)(dian)(dian)插口(kou)，而(er)5000毫安甚至(zhi)(zhi)以上即(ji)便的產品會(hui)配備兩個(ge)甚至(zhi)(zhi)更多個(ge)USB接(jie)口(kou)。這樣(yang)(yang)做(zuo)最大的好處就(jiu)是可以同時(shi)給多臺設備充(chong)(chong)電(dian)(dian)(dian)，從而(er)達到節省時(shi)間的目的。不(bu)過，這樣(yang)(yang)做(zuo)也會(hui)有弊(bi)端，比如多口(kou)設備同時(shi)工(gong)作的時(shi)候，每個(ge)接(jie)口(kou)不(bu)可能達到宣稱的電(dian)(dian)(dian)流(liu)輸出(chu)指標(biao)，下降(jiang)是必須的。這就(jiu)對移動(dong)電(dian)(dian)(dian)源本(ben)身(shen)的電(dian)(dian)(dian)路和品質(zhi)有著(zhu)較高的要(yao)求(qiu)，用戶在購買(mai)時(shi)需(xu)要(yao)注意挑選(xuan)。

可調輸出(chu)電(dian)(dian)(dian)(dian)流：需要注意的(de)(de)(de)是(shi)，以(yi)上所(suo)(suo)提到的(de)(de)(de)USB充(chong)電(dian)(dian)(dian)(dian)口(kou)(kou)輸出(chu)電(dian)(dian)(dian)(dian)流基(ji)本都(dou)是(shi)1A，這(zhe)就(jiu)意味(wei)著這(zhe)樣的(de)(de)(de)移(yi)動(dong)電(dian)(dian)(dian)(dian)源是(shi)無法為iPad等大電(dian)(dian)(dian)(dian)流的(de)(de)(de)產(chan)品充(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)，所(suo)(suo)以(yi)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流可調的(de)(de)(de)移(yi)動(dong)電(dian)(dian)(dian)(dian)源就(jiu)應運而生(sheng)。這(zhe)樣的(de)(de)(de)移(yi)動(dong)電(dian)(dian)(dian)(dian)源一般(ban)標配多個充(chong)電(dian)(dian)(dian)(dian)輸出(chu)口(kou)(kou)，而每個輸出(chu)口(kou)(kou)的(de)(de)(de)輸出(chu)電(dian)(dian)(dian)(dian)流會在(zai)明(ming)顯的(de)(de)(de)位置(zhi)加以(yi)標注，比如1A、2A等字樣，用戶(hu)可以(yi)根據自身的(de)(de)(de)實際使(shi)用需求(qiu)來選擇(ze)。另外，還有一種(zhong)單口(kou)(kou)輸出(chu)、多種(zhong)電(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)壓可調的(de)(de)(de)移(yi)動(dong)電(dian)(dian)(dian)(dian)源，由于此類產(chan)品價格高(gao)昂、體積龐大、重(zhong)量也難以(yi)接(jie)受(shou)，普通用戶(hu)在(zai)使(shi)用中很(hen)難碰到，所(suo)(suo)以(yi)我們在(zai)此一筆帶(dai)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(de)(de)充(chong)電(dian)截止閥值是(shi)以(yi)電(dian)壓(ya)來計算的(de)(de)，用(yong)不(bu)同電(dian)流輸出的(de)(de)插孔(kong)為同一(yi)臺手機充(chong)電(dian)，只會(hui)獲得更快的(de)(de)充(chong)電(dian)速度，對手機其(qi)它(ta)部分沒有影響，更不(bu)會(hui)損壞手機。

缺點：唯(wei)一不(bu)好的(de)(de)(de)(de)(de)地方就(jiu)是，大電(dian)流(liu)充(chong)電(dian)會帶來(lai)較(jiao)高的(de)(de)(de)(de)(de)熱量，這對于電(dian)子元件的(de)(de)(de)(de)(de)保(bao)護、保(bao)養(yang)是沒有好處的(de)(de)(de)(de)(de)，可能會加速電(dian)子元件的(de)(de)(de)(de)(de)老化(hua)。如果(guo)用戶不(bu)是很有必要用大電(dian)流(liu)對手(shou)機進行充(chong)電(dian)的(de)(de)(de)(de)(de)話，我們還是建議按(an)照(zhao)手(shou)機說明書上要求的(de)(de)(de)(de)(de)額定(ding)電(dian)流(liu)充(chong)電(dian)，這樣來(lai)的(de)(de)(de)(de)(de)比較(jiao)穩(wen)妥。

充電寶給手機充電斷開的原因

很多網友(you)反映，購買到的充(chong)電(dian)寶給(gei)手機(ji)充(chong)電(dian)時，充(chong)一(yi)會兒就斷(duan)開了，這種情況，一(yi)般(ban)來說與(yu)移(yi)動(dong)電(dian)源的質量有關(guan)，主要有如下幾個因素：

1、充電寶輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)不夠。這是(shi)根(gen)據充(chong)電(dian)(dian)(dian)(dian)原理決定(ding)的，必須(xu)是(shi)高電(dian)(dian)(dian)(dian)壓(ya)(ya)流(liu)向低電(dian)(dian)(dian)(dian)壓(ya)(ya)，手機一(yi)般(ban)是(shi)3.7V，移(yi)動(dong)電(dian)(dian)(dian)(dian)源鋰電(dian)(dian)(dian)(dian)芯是(shi)3.7V，這樣(yang)就是(shi)平級(ji)的，因此移(yi)動(dong)電(dian)(dian)(dian)(dian)源在輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)時，會進行升壓(ya)(ya)到5V，這樣(yang)就產生高電(dian)(dian)(dian)(dian)壓(ya)(ya)流(liu)向低電(dian)(dian)(dian)(dian)壓(ya)(ya)，進行充(chong)電(dian)(dian)(dian)(dian)。

2、充(chong)電(dian)(dian)(dian)(dian)寶輸出電(dian)(dian)(dian)(dian)流強度不夠。我們在測試一些移動電(dian)(dian)(dian)(dian)源的(de)時候，上(shang)面(mian)標稱(cheng)有800mAh放電(dian)(dian)(dian)(dian)，但是有時根本不能以這(zhe)(zhe)個規格進行(xing)放電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)流強度不夠時也會(hui)發生這(zhe)(zhe)種現(xian)象(xiang)，這(zhe)(zhe)個和電(dian)(dian)(dian)(dian)壓息息相(xiang)關，最(zui)根本的(de)還是鋰電(dian)(dian)(dian)(dian)芯質(zhi)量(liang)不好所致。

3、與手機(ji)本身有關。可(ke)能(neng)手機(ji)電阻(zu)值過大，其(qi)實這種情(qing)況的可(ke)能(neng)性非常少。只(zhi)是(shi)在此提及。

4、與移動(dong)電(dian)源的PCBA保(bao)(bao)護(hu)(hu)板(ban)有(you)關。在第1點提到，保(bao)(bao)護(hu)(hu)板(ban)要起到過流過充過放的功能，同時還有(you)一(yi)個MCU，這個就是(shi)用來升壓，如果保(bao)(bao)護(hu)(hu)板(ban)質量(liang)不好，在電(dian)流穿過時就不穩定，導至PCBA怠工，然后導致(zhi)充電(dian)寶無(wu)法充電(dian)，發生(sheng)上述的情況。
