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

說到移動電源，我們不(bu)得不(bu)引(yin)入充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)寶充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時間(jian)(jian)這(zhe)(zhe)個概念。這(zhe)(zhe)里(li)并不(bu)是指移(yi)動電(dian)(dian)(dian)(dian)源(yuan)對手機(ji)設備的(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時間(jian)(jian)，而是電(dian)(dian)(dian)(dian)源(yuan)給移(yi)動電(dian)(dian)(dian)(dian)源(yuan)的(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時間(jian)(jian)。這(zhe)(zhe)里(li)有一個算(suan)法，用(yong)移(yi)動電(dian)(dian)(dian)(dian)源(yuan)的(de)容(rong)量(liang)除以(yi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流，再(zai)除以(yi)一個0.8的(de)做功轉換系數(shu)，得出的(de)時間(jian)(jian)基(ji)本就是充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時間(jian)(jian)了。舉例來(lai)說，一個容(rong)量(liang)為5000毫安的(de)移(yi)動電(dian)(dian)(dian)(dian)源(yuan)，用(yong)1A的(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)進行充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，根(gen)據上面的(de)算(suan)法，大概6個多小(xiao)時就可以(yi)充(chong)(chong)(chong)(chong)(chong)滿(man)。

在選擇移(yi)(yi)動電源(yuan)時(shi)，應當注意充電時(shi)間，即便(bian)是(shi)晚上(shang)(shang)充電白天(tian)使用的(de)話，如果超過8個小時(shi)，這很難與現(xian)代人的(de)作息習(xi)慣相(xiang)吻合(he)：早上(shang)(shang)起來發(fa)現(xian)昨晚插上(shang)(shang)的(de)移(yi)(yi)動電源(yuan)竟然還(huan)在充電，這是(shi)讓人非常不(bu)爽(shuang)的(de)一件事情(qing)。

充電寶怎么充電

如果是普(pu)通充(chong)手機(ji)之類的(de)(de)(de)數碼產品，那么(me)普(pu)通的(de)(de)(de)1A電流輸出的(de)(de)(de)移(yi)動電源已經完全夠(gou)用了，但如果要是充(chong)iPad的(de)(de)(de)話就需要2A以上的(de)(de)(de)電流的(de)(de)(de)，否則即(ji)便(bian)是連接上也(ye)會顯示該設(she)備不在充(chong)電，用戶可以根據自(zi)己的(de)(de)(de)事情(qing)情(qing)況加以選擇。

1A輸出電(dian)流(liu)：主(zhu)流(liu)的(de)(de)移(yi)動(dong)電(dian)源(yuan)一般(ban)為一個USB充(chong)電(dian)插(cha)口，而5000毫(hao)安甚至以(yi)上即(ji)便的(de)(de)產品會(hui)(hui)配備兩(liang)個甚至更多(duo)個USB接口。這樣做(zuo)(zuo)最(zui)大(da)的(de)(de)好處就是可(ke)以(yi)同時給多(duo)臺設備充(chong)電(dian)，從(cong)而達(da)到節省(sheng)時間(jian)的(de)(de)目的(de)(de)。不過(guo)，這樣做(zuo)(zuo)也會(hui)(hui)有(you)弊(bi)端，比(bi)如(ru)多(duo)口設備同時工作的(de)(de)時候(hou)，每個接口不可(ke)能(neng)達(da)到宣(xuan)稱(cheng)的(de)(de)電(dian)流(liu)輸出指標，下降(jiang)是必須(xu)的(de)(de)。這就對移(yi)動(dong)電(dian)源(yuan)本身的(de)(de)電(dian)路和(he)品質有(you)著較高的(de)(de)要求，用戶在購買時需要注意挑選。

可(ke)調輸(shu)(shu)出電(dian)(dian)(dian)(dian)流(liu)：需(xu)要注(zhu)意的(de)是(shi)，以上所提到(dao)的(de)USB充(chong)電(dian)(dian)(dian)(dian)口輸(shu)(shu)出電(dian)(dian)(dian)(dian)流(liu)基本(ben)都是(shi)1A，這就意味著這樣(yang)(yang)的(de)移動(dong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)是(shi)無法為iPad等大(da)電(dian)(dian)(dian)(dian)流(liu)的(de)產品(pin)充(chong)電(dian)(dian)(dian)(dian)的(de)，所以充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)可(ke)調的(de)移動(dong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)就應運而(er)生。這樣(yang)(yang)的(de)移動(dong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)一(yi)般(ban)標配多個充(chong)電(dian)(dian)(dian)(dian)輸(shu)(shu)出口，而(er)每個輸(shu)(shu)出口的(de)輸(shu)(shu)出電(dian)(dian)(dian)(dian)流(liu)會在(zai)(zai)明顯的(de)位置加以標注(zhu)，比如1A、2A等字(zi)樣(yang)(yang)，用(yong)(yong)戶(hu)可(ke)以根據自(zi)身(shen)的(de)實際使(shi)用(yong)(yong)需(xu)求來(lai)選擇。另外，還有一(yi)種(zhong)(zhong)單口輸(shu)(shu)出、多種(zhong)(zhong)電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)壓可(ke)調的(de)移動(dong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)，由于此(ci)類(lei)產品(pin)價(jia)格高昂、體(ti)積龐大(da)、重(zhong)量也難以接(jie)受，普通用(yong)(yong)戶(hu)在(zai)(zai)使(shi)用(yong)(yong)中很難碰到(dao)，所以我們在(zai)(zai)此(ci)一(yi)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(you)點：鋰電(dian)(dian)(dian)池的(de)充(chong)電(dian)(dian)(dian)截止閥值是以電(dian)(dian)(dian)壓(ya)來(lai)計算(suan)的(de)，用(yong)不同(tong)電(dian)(dian)(dian)流輸出的(de)插孔(kong)為同(tong)一臺手(shou)機(ji)充(chong)電(dian)(dian)(dian)，只會獲得更快的(de)充(chong)電(dian)(dian)(dian)速度，對手(shou)機(ji)其它部分沒有影響，更不會損(sun)壞手(shou)機(ji)。

缺點：唯一不(bu)好的(de)(de)地方就是(shi)，大電(dian)(dian)(dian)(dian)流充電(dian)(dian)(dian)(dian)會帶(dai)來較高(gao)的(de)(de)熱量，這(zhe)對于電(dian)(dian)(dian)(dian)子(zi)元件(jian)的(de)(de)保(bao)護、保(bao)養是(shi)沒有(you)好處的(de)(de)，可能(neng)會加速(su)電(dian)(dian)(dian)(dian)子(zi)元件(jian)的(de)(de)老化。如果用戶不(bu)是(shi)很(hen)有(you)必要(yao)用大電(dian)(dian)(dian)(dian)流對手(shou)機(ji)進(jin)行充電(dian)(dian)(dian)(dian)的(de)(de)話，我們還是(shi)建議(yi)按(an)照手(shou)機(ji)說明(ming)書上要(yao)求的(de)(de)額定電(dian)(dian)(dian)(dian)流充電(dian)(dian)(dian)(dian)，這(zhe)樣來的(de)(de)比較穩妥(tuo)。

充電寶給手機充電斷開的原因

很多網友反映(ying)，購買到(dao)的充電寶給手機充電時，充一會兒就斷(duan)開了，這種情況，一般來說(shuo)與移動(dong)電源的質量有關，主(zhu)要有如下幾個因素：

1、充電寶輸出電(dian)(dian)壓(ya)不夠。這(zhe)(zhe)是(shi)(shi)(shi)(shi)根據充電(dian)(dian)原(yuan)理(li)決定的，必須是(shi)(shi)(shi)(shi)高電(dian)(dian)壓(ya)流向低電(dian)(dian)壓(ya)，手機一(yi)般是(shi)(shi)(shi)(shi)3.7V，移(yi)動電(dian)(dian)源(yuan)鋰電(dian)(dian)芯是(shi)(shi)(shi)(shi)3.7V，這(zhe)(zhe)樣(yang)就(jiu)是(shi)(shi)(shi)(shi)平級(ji)的，因(yin)此移(yi)動電(dian)(dian)源(yuan)在輸出電(dian)(dian)壓(ya)時，會進行升壓(ya)到(dao)5V，這(zhe)(zhe)樣(yang)就(jiu)產生高電(dian)(dian)壓(ya)流向低電(dian)(dian)壓(ya)，進行充電(dian)(dian)。

2、充電(dian)(dian)寶(bao)輸出電(dian)(dian)流(liu)(liu)強度不夠。我(wo)們在測試一些移(yi)動電(dian)(dian)源的時(shi)候，上面標稱有(you)800mAh放電(dian)(dian)，但是有(you)時(shi)根本不能以這個(ge)規格進行放電(dian)(dian)，電(dian)(dian)流(liu)(liu)強度不夠時(shi)也會發(fa)生這種現象，這個(ge)和電(dian)(dian)壓(ya)息息相關，最根本的還(huan)是鋰(li)電(dian)(dian)芯(xin)質量不好所致(zhi)。

3、與手機本身(shen)有關(guan)。可能(neng)手機電阻值過大，其實這種情況的可能(neng)性非常少。只(zhi)是(shi)在(zai)此提及。

4、與移動電(dian)(dian)源的(de)PCBA保(bao)(bao)護(hu)板有關。在第(di)1點提到，保(bao)(bao)護(hu)板要起到過流(liu)過充過放(fang)的(de)功能，同(tong)時(shi)還(huan)有一個MCU，這個就是(shi)用(yong)來(lai)升壓，如(ru)果(guo)保(bao)(bao)護(hu)板質量不(bu)好，在電(dian)(dian)流(liu)穿過時(shi)就不(bu)穩(wen)定，導(dao)至PCBA怠工(gong)，然后導(dao)致充電(dian)(dian)寶無法充電(dian)(dian)，發(fa)生(sheng)上述的(de)情況。
