說到移動電源，我們不(bu)得不(bu)引入充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)寶(bao)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間(jian)這(zhe)個(ge)概(gai)(gai)念。這(zhe)里并不(bu)是指移(yi)(yi)動電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)對手機設備的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間(jian)，而(er)是電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)給(gei)移(yi)(yi)動電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間(jian)。這(zhe)里有一個(ge)算(suan)法，用(yong)移(yi)(yi)動電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)(de)(de)容量除以(yi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流，再除以(yi)一個(ge)0.8的(de)(de)(de)做功(gong)轉換(huan)系數，得出的(de)(de)(de)時(shi)間(jian)基(ji)本(ben)就是充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間(jian)了。舉例來說，一個(ge)容量為5000毫安的(de)(de)(de)移(yi)(yi)動電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，用(yong)1A的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器進行(xing)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，根據上面的(de)(de)(de)算(suan)法，大概(gai)(gai)6個(ge)多小時(shi)就可(ke)以(yi)充(chong)(chong)(chong)滿。

在選擇移動(dong)電(dian)源時，應(ying)當注意充(chong)電(dian)時間，即便是(shi)晚(wan)上(shang)充(chong)電(dian)白天使用的(de)話，如果超過8個小時，這(zhe)很難與現代人(ren)(ren)的(de)作息習慣相吻(wen)合：早上(shang)起(qi)來發現昨晚(wan)插上(shang)的(de)移動(dong)電(dian)源竟然還(huan)在充(chong)電(dian)，這(zhe)是(shi)讓人(ren)(ren)非常(chang)不爽(shuang)的(de)一(yi)件(jian)事情。

充電寶怎么充電

如果是普通充手機(ji)之類的(de)(de)數(shu)碼(ma)產(chan)品(pin)，那么普通的(de)(de)1A電(dian)流輸出的(de)(de)移動電(dian)源已經(jing)完全夠用(yong)了，但如果要(yao)是充iPad的(de)(de)話就(jiu)需(xu)要(yao)2A以上的(de)(de)電(dian)流的(de)(de)，否則即便是連接上也會顯(xian)示該設(she)備不(bu)在充電(dian)，用(yong)戶可以根據自己的(de)(de)事情情況(kuang)加以選擇(ze)。

1A輸(shu)出電(dian)流：主流的(de)(de)移動(dong)電(dian)源(yuan)一(yi)般為一(yi)個USB充(chong)電(dian)插口(kou)，而5000毫安甚(shen)至以(yi)上即便(bian)的(de)(de)產品(pin)會配(pei)備兩個甚(shen)至更多個USB接(jie)口(kou)。這樣做最大的(de)(de)好處就是可(ke)以(yi)同時給多臺設(she)備充(chong)電(dian)，從(cong)而達到節省時間的(de)(de)目的(de)(de)。不過，這樣做也(ye)會有弊端，比如多口(kou)設(she)備同時工作(zuo)的(de)(de)時候，每個接(jie)口(kou)不可(ke)能(neng)達到宣稱(cheng)的(de)(de)電(dian)流輸(shu)出指標，下降是必須的(de)(de)。這就對移動(dong)電(dian)源(yuan)本身的(de)(de)電(dian)路和品(pin)質有著較高的(de)(de)要求，用(yong)戶(hu)在購買時需要注意挑選。

可(ke)調(diao)輸(shu)(shu)(shu)出(chu)(chu)電(dian)(dian)流(liu)(liu)(liu)：需要注(zhu)意的(de)是(shi)，以(yi)(yi)(yi)上所提到(dao)的(de)USB充(chong)電(dian)(dian)口輸(shu)(shu)(shu)出(chu)(chu)電(dian)(dian)流(liu)(liu)(liu)基本都(dou)是(shi)1A，這(zhe)(zhe)就意味(wei)著這(zhe)(zhe)樣(yang)的(de)移(yi)(yi)動電(dian)(dian)源(yuan)(yuan)是(shi)無(wu)法為iPad等(deng)大(da)電(dian)(dian)流(liu)(liu)(liu)的(de)產(chan)品(pin)充(chong)電(dian)(dian)的(de)，所以(yi)(yi)(yi)充(chong)電(dian)(dian)電(dian)(dian)流(liu)(liu)(liu)可(ke)調(diao)的(de)移(yi)(yi)動電(dian)(dian)源(yuan)(yuan)就應運而(er)生。這(zhe)(zhe)樣(yang)的(de)移(yi)(yi)動電(dian)(dian)源(yuan)(yuan)一般(ban)標(biao)配多(duo)個充(chong)電(dian)(dian)輸(shu)(shu)(shu)出(chu)(chu)口，而(er)每個輸(shu)(shu)(shu)出(chu)(chu)口的(de)輸(shu)(shu)(shu)出(chu)(chu)電(dian)(dian)流(liu)(liu)(liu)會(hui)在(zai)(zai)明(ming)顯(xian)的(de)位置加以(yi)(yi)(yi)標(biao)注(zhu)，比如1A、2A等(deng)字樣(yang)，用戶(hu)可(ke)以(yi)(yi)(yi)根據自身的(de)實際使(shi)用需求來(lai)選擇(ze)。另外，還有(you)一種(zhong)單口輸(shu)(shu)(shu)出(chu)(chu)、多(duo)種(zhong)電(dian)(dian)流(liu)(liu)(liu)電(dian)(dian)壓(ya)可(ke)調(diao)的(de)移(yi)(yi)動電(dian)(dian)源(yuan)(yuan)，由于此(ci)類(lei)產(chan)品(pin)價格高(gao)昂(ang)、體(ti)積(ji)龐大(da)、重量也難以(yi)(yi)(yi)接受，普(pu)通用戶(hu)在(zai)(zai)使(shi)用中(zhong)很難碰到(dao)，所以(yi)(yi)(yi)我們在(zai)(zai)此(ci)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：鋰電(dian)(dian)池的(de)(de)充(chong)電(dian)(dian)截止閥(fa)值是以電(dian)(dian)壓來計算的(de)(de)，用(yong)不同電(dian)(dian)流輸出的(de)(de)插孔為同一臺手(shou)機(ji)充(chong)電(dian)(dian)，只會獲得更快(kuai)的(de)(de)充(chong)電(dian)(dian)速度，對手(shou)機(ji)其它部(bu)分沒有影響，更不會損(sun)壞手(shou)機(ji)。

缺(que)點：唯(wei)一(yi)不(bu)好的地方就是，大(da)電(dian)(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)(dian)會帶來較高的熱(re)量，這對于(yu)電(dian)(dian)(dian)(dian)子元(yuan)件的保(bao)(bao)護、保(bao)(bao)養是沒有(you)好處(chu)的，可能會加速(su)電(dian)(dian)(dian)(dian)子元(yuan)件的老化。如果用戶不(bu)是很有(you)必(bi)要(yao)(yao)用大(da)電(dian)(dian)(dian)(dian)流對手(shou)機(ji)進行充(chong)電(dian)(dian)(dian)(dian)的話(hua)，我們還(huan)是建議按照手(shou)機(ji)說明(ming)書上要(yao)(yao)求的額定電(dian)(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)(dian)，這樣來的比較穩妥。

充電寶給手機充電斷開的原因

很多網(wang)友反映，購買到的充(chong)電寶給手機充(chong)電時，充(chong)一會兒(er)就斷開了，這種(zhong)情(qing)況，一般(ban)來說與移動電源的質量有關(guan)，主要有如(ru)下幾個因素：

1、充電寶輸出電壓(ya)(ya)不夠。這是(shi)(shi)根(gen)據充(chong)電原理決定的，必須是(shi)(shi)高(gao)電壓(ya)(ya)流(liu)向低電壓(ya)(ya)，手機一般是(shi)(shi)3.7V，移(yi)(yi)動電源鋰(li)電芯是(shi)(shi)3.7V，這樣就是(shi)(shi)平級的，因此移(yi)(yi)動電源在輸出電壓(ya)(ya)時，會進行(xing)升壓(ya)(ya)到5V，這樣就產(chan)生(sheng)高(gao)電壓(ya)(ya)流(liu)向低電壓(ya)(ya)，進行(xing)充(chong)電。

2、充電(dian)(dian)寶輸出電(dian)(dian)流(liu)強度(du)不(bu)夠。我們在測試一些移動(dong)電(dian)(dian)源的(de)時候，上面標稱有800mAh放(fang)電(dian)(dian)，但是有時根(gen)本不(bu)能以這(zhe)個規格(ge)進行放(fang)電(dian)(dian)，電(dian)(dian)流(liu)強度(du)不(bu)夠時也會(hui)發生這(zhe)種現(xian)象，這(zhe)個和(he)電(dian)(dian)壓息息相關，最根(gen)本的(de)還是鋰電(dian)(dian)芯質量不(bu)好所致。

3、與(yu)手(shou)機本身有(you)關(guan)。可能手(shou)機電阻值過大(da)，其(qi)實這種情況(kuang)的可能性(xing)非常少。只(zhi)是(shi)在此(ci)提及。

4、與移動電(dian)(dian)源的PCBA保(bao)護板有關。在第1點提到(dao)，保(bao)護板要起到(dao)過(guo)流過(guo)充過(guo)放的功能，同時還(huan)有一個MCU，這個就是用來(lai)升壓，如(ru)果保(bao)護板質量不好，在電(dian)(dian)流穿過(guo)時就不穩定(ding)，導至PCBA怠工，然后導致(zhi)充電(dian)(dian)寶無法(fa)充電(dian)(dian)，發(fa)生上述的情況。
