【手機伴侶(lv)充電寶】充電寶怎么充電 充電寶充電時間多久合(he)適

說到移動電源，我們不(bu)得(de)(de)不(bu)引(yin)入充(chong)(chong)電(dian)(dian)(dian)寶充(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)這個(ge)概念(nian)。這里(li)并不(bu)是指移動(dong)電(dian)(dian)(dian)源(yuan)(yuan)對手機設備(bei)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)，而是電(dian)(dian)(dian)源(yuan)(yuan)給移動(dong)電(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)。這里(li)有一(yi)個(ge)算法，用(yong)移動(dong)電(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)容量除以充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流，再除以一(yi)個(ge)0.8的(de)(de)做功(gong)轉換系數，得(de)(de)出的(de)(de)時(shi)(shi)間(jian)基本就(jiu)是充(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)了。舉例來說(shuo)，一(yi)個(ge)容量為(wei)5000毫安(an)的(de)(de)移動(dong)電(dian)(dian)(dian)源(yuan)(yuan)，用(yong)1A的(de)(de)充(chong)(chong)電(dian)(dian)(dian)器進行充(chong)(chong)電(dian)(dian)(dian)，根據(ju)上面的(de)(de)算法，大概6個(ge)多(duo)小時(shi)(shi)就(jiu)可(ke)以充(chong)(chong)滿。

在選擇(ze)移(yi)動電(dian)源時，應(ying)當注意充電(dian)時間，即便是(shi)晚(wan)上(shang)充電(dian)白(bai)天使用的(de)話，如果超過8個小時，這很難與現(xian)代(dai)人的(de)作息習慣相吻合：早上(shang)起來發現(xian)昨(zuo)晚(wan)插上(shang)的(de)移(yi)動電(dian)源竟然還在充電(dian)，這是(shi)讓人非常不爽的(de)一件(jian)事情(qing)。

充電寶怎么充電

如(ru)果是普通充(chong)手機(ji)之類的數碼產品，那么普通的1A電流輸出(chu)的移(yi)動電源已經(jing)完全(quan)夠用(yong)了，但如(ru)果要(yao)是充(chong)iPad的話(hua)就需要(yao)2A以上的電流的，否則即便是連接上也(ye)會顯示該設備不在充(chong)電，用(yong)戶可以根據自己(ji)的事情情況(kuang)加以選擇。

1A輸出電(dian)流：主流的移動(dong)(dong)電(dian)源一(yi)般為(wei)一(yi)個(ge)USB充電(dian)插口，而5000毫安甚(shen)至(zhi)以上即便的產品(pin)(pin)會配(pei)備(bei)(bei)兩(liang)個(ge)甚(shen)至(zhi)更多個(ge)USB接(jie)口。這(zhe)樣(yang)做最大(da)的好處(chu)就是可以同時(shi)給多臺設(she)備(bei)(bei)充電(dian)，從(cong)而達到(dao)節省時(shi)間的目的。不過，這(zhe)樣(yang)做也(ye)會有(you)弊(bi)端，比如多口設(she)備(bei)(bei)同時(shi)工作的時(shi)候(hou)，每個(ge)接(jie)口不可能達到(dao)宣稱的電(dian)流輸出指標，下降是必須(xu)的。這(zhe)就對移動(dong)(dong)電(dian)源本(ben)身(shen)的電(dian)路和品(pin)(pin)質有(you)著較高的要求(qiu)，用(yong)戶在購買時(shi)需(xu)要注(zhu)意挑(tiao)選。

可(ke)調輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)：需要注意的(de)(de)(de)(de)是(shi)，以(yi)上所(suo)提到(dao)的(de)(de)(de)(de)USB充電(dian)(dian)(dian)(dian)(dian)口輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)基(ji)本都(dou)是(shi)1A，這就意味著(zhu)這樣(yang)(yang)(yang)的(de)(de)(de)(de)移(yi)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)源(yuan)是(shi)無法為iPad等(deng)(deng)大電(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)產品(pin)(pin)充電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)，所(suo)以(yi)充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)可(ke)調的(de)(de)(de)(de)移(yi)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)源(yuan)就應運而(er)生。這樣(yang)(yang)(yang)的(de)(de)(de)(de)移(yi)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)源(yuan)一(yi)般標配多個充電(dian)(dian)(dian)(dian)(dian)輸(shu)出(chu)口，而(er)每個輸(shu)出(chu)口的(de)(de)(de)(de)輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)會(hui)在(zai)明顯的(de)(de)(de)(de)位(wei)置加以(yi)標注，比(bi)如1A、2A等(deng)(deng)字樣(yang)(yang)(yang)，用戶可(ke)以(yi)根據自(zi)身的(de)(de)(de)(de)實際(ji)使(shi)(shi)用需求(qiu)來選擇。另外，還有一(yi)種單口輸(shu)出(chu)、多種電(dian)(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)(dian)壓可(ke)調的(de)(de)(de)(de)移(yi)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)源(yuan)，由于此類(lei)產品(pin)(pin)價格高昂、體(ti)積龐大、重量也難(nan)以(yi)接受(shou)，普(pu)通用戶在(zai)使(shi)(shi)用中很難(nan)碰到(dao)，所(suo)以(yi)我們在(zai)此一(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

優點：鋰電(dian)(dian)池的(de)充電(dian)(dian)截止閥值是以電(dian)(dian)壓來計(ji)算(suan)的(de)，用(yong)不(bu)同(tong)電(dian)(dian)流輸出的(de)插孔為同(tong)一(yi)臺(tai)手(shou)機充電(dian)(dian)，只會獲得更(geng)(geng)快的(de)充電(dian)(dian)速度，對手(shou)機其(qi)它部分(fen)沒有影響，更(geng)(geng)不(bu)會損壞(huai)手(shou)機。

缺點：唯(wei)一不(bu)好的(de)地(di)方就是(shi)，大電(dian)(dian)(dian)(dian)(dian)流(liu)充電(dian)(dian)(dian)(dian)(dian)會帶來較(jiao)高的(de)熱量(liang)，這對(dui)于(yu)電(dian)(dian)(dian)(dian)(dian)子元件(jian)的(de)保護、保養是(shi)沒有好處的(de)，可(ke)能會加速電(dian)(dian)(dian)(dian)(dian)子元件(jian)的(de)老化(hua)。如果用戶不(bu)是(shi)很有必要(yao)用大電(dian)(dian)(dian)(dian)(dian)流(liu)對(dui)手(shou)機進(jin)行充電(dian)(dian)(dian)(dian)(dian)的(de)話(hua)，我(wo)們還是(shi)建議按照手(shou)機說明書上(shang)要(yao)求的(de)額(e)定電(dian)(dian)(dian)(dian)(dian)流(liu)充電(dian)(dian)(dian)(dian)(dian)，這樣來的(de)比較(jiao)穩(wen)妥(tuo)。

充電寶給手機充電斷開的原因

很(hen)多(duo)網友反映，購買到的充電(dian)寶給(gei)手機充電(dian)時，充一會兒就斷開(kai)了，這種情況，一般來說與移(yi)動(dong)電(dian)源(yuan)的質(zhi)量有關，主要有如下幾個(ge)因素：

1、充電寶輸(shu)出(chu)(chu)電壓(ya)(ya)不夠。這(zhe)(zhe)是(shi)根據(ju)充(chong)電原(yuan)理決定的，必(bi)須是(shi)高電壓(ya)(ya)流(liu)向(xiang)低(di)電壓(ya)(ya)，手機一(yi)般是(shi)3.7V，移動(dong)電源鋰電芯是(shi)3.7V，這(zhe)(zhe)樣就是(shi)平級的，因此移動(dong)電源在(zai)輸(shu)出(chu)(chu)電壓(ya)(ya)時，會進(jin)行升壓(ya)(ya)到5V，這(zhe)(zhe)樣就產生(sheng)高電壓(ya)(ya)流(liu)向(xiang)低(di)電壓(ya)(ya)，進(jin)行充(chong)電。

2、充電(dian)(dian)(dian)寶(bao)輸出電(dian)(dian)(dian)流(liu)強度(du)不夠。我們在測試一些(xie)移(yi)動電(dian)(dian)(dian)源的時候，上面標稱有800mAh放電(dian)(dian)(dian)，但是有時根本不能(neng)以(yi)這(zhe)個(ge)規格(ge)進行放電(dian)(dian)(dian)，電(dian)(dian)(dian)流(liu)強度(du)不夠時也會發生這(zhe)種現象(xiang)，這(zhe)個(ge)和電(dian)(dian)(dian)壓(ya)息息相關，最(zui)根本的還(huan)是鋰電(dian)(dian)(dian)芯質量不好所(suo)致。

3、與手機本身有關。可能手機電(dian)阻(zu)值過大，其實這種(zhong)情況的可能性非常少。只(zhi)是在此提及。

4、與移動(dong)電(dian)源的PCBA保護板(ban)有關。在第1點提(ti)到(dao)，保護板(ban)要起到(dao)過(guo)流(liu)過(guo)充(chong)過(guo)放(fang)的功能，同(tong)時還有一(yi)個(ge)(ge)MCU，這(zhe)個(ge)(ge)就是(shi)用來升壓，如果保護板(ban)質量不好，在電(dian)流(liu)穿(chuan)過(guo)時就不穩定，導至PCBA怠工(gong)，然后(hou)導致充(chong)電(dian)寶無法充(chong)電(dian)，發生上述的情況(kuang)。
