【手(shou)機伴(ban)侶(lv)充(chong)電(dian)(dian)(dian)寶(bao)(bao)】充(chong)電(dian)(dian)(dian)寶(bao)(bao)怎么(me)充(chong)電(dian)(dian)(dian) 充(chong)電(dian)(dian)(dian)寶(bao)(bao)充(chong)電(dian)(dian)(dian)時間多久合適

說到移動電源，我們不(bu)得(de)不(bu)引入充(chong)電(dian)(dian)(dian)(dian)寶(bao)充(chong)電(dian)(dian)(dian)(dian)時間(jian)(jian)這個(ge)概念。這里并不(bu)是指移動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)對手機設備(bei)的(de)充(chong)電(dian)(dian)(dian)(dian)時間(jian)(jian)，而是電(dian)(dian)(dian)(dian)源(yuan)給移動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)的(de)充(chong)電(dian)(dian)(dian)(dian)時間(jian)(jian)。這里有(you)一個(ge)算法，用(yong)移動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)的(de)容量(liang)除(chu)(chu)以充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流，再除(chu)(chu)以一個(ge)0.8的(de)做功轉換系數，得(de)出的(de)時間(jian)(jian)基本就(jiu)(jiu)是充(chong)電(dian)(dian)(dian)(dian)時間(jian)(jian)了。舉例來(lai)說，一個(ge)容量(liang)為5000毫安的(de)移動(dong)(dong)電(dian)(dian)(dian)(dian)源(yuan)，用(yong)1A的(de)充(chong)電(dian)(dian)(dian)(dian)器進(jin)行(xing)充(chong)電(dian)(dian)(dian)(dian)，根(gen)據上面的(de)算法，大概6個(ge)多小時就(jiu)(jiu)可以充(chong)滿(man)。

在選擇移動電源時，應(ying)當(dang)注意充(chong)電時間，即便(bian)是晚(wan)上充(chong)電白天使用的話(hua)，如果超過8個小時，這很難與現(xian)代人(ren)的作息習慣(guan)相吻合：早上起來發(fa)現(xian)昨晚(wan)插(cha)上的移動電源竟(jing)然還(huan)在充(chong)電，這是讓人(ren)非(fei)常不爽(shuang)的一件事情。

充電寶怎么充電

如(ru)果是普通充手機之類的數碼產(chan)品(pin)，那么普通的1A電流輸(shu)出的移動電源(yuan)已經完全(quan)夠用(yong)了(le)，但(dan)如(ru)果要是充iPad的話就(jiu)需要2A以上(shang)的電流的，否(fou)則即(ji)便是連接上(shang)也會顯示該(gai)設備不(bu)在充電，用(yong)戶可以根據自己(ji)的事情(qing)情(qing)況加(jia)以選擇(ze)。

1A輸出電(dian)流：主(zhu)流的移動電(dian)源一般為一個(ge)USB充電(dian)插口(kou)，而(er)5000毫安甚至以(yi)上即便的產品會配(pei)備(bei)(bei)兩個(ge)甚至更多(duo)個(ge)USB接口(kou)。這(zhe)(zhe)樣做最大的好處就(jiu)是可(ke)以(yi)同時給多(duo)臺設(she)備(bei)(bei)充電(dian)，從而(er)達(da)到節(jie)省(sheng)時間的目(mu)的。不(bu)過(guo)，這(zhe)(zhe)樣做也會有(you)弊端，比如(ru)多(duo)口(kou)設(she)備(bei)(bei)同時工作(zuo)的時候，每個(ge)接口(kou)不(bu)可(ke)能達(da)到宣稱的電(dian)流輸出指標，下降(jiang)是必(bi)須(xu)的。這(zhe)(zhe)就(jiu)對移動電(dian)源本身的電(dian)路(lu)和品質(zhi)有(you)著較高的要求，用戶在購買時需要注意挑選。

可(ke)調輸(shu)出(chu)電(dian)(dian)(dian)(dian)流：需要注意(yi)的(de)(de)(de)(de)(de)(de)是，以(yi)(yi)上所(suo)提到(dao)的(de)(de)(de)(de)(de)(de)USB充(chong)電(dian)(dian)(dian)(dian)口(kou)輸(shu)出(chu)電(dian)(dian)(dian)(dian)流基本都是1A，這就意(yi)味著這樣(yang)的(de)(de)(de)(de)(de)(de)移(yi)動電(dian)(dian)(dian)(dian)源(yuan)是無法為iPad等大電(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)(de)(de)產品充(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)(de)，所(suo)以(yi)(yi)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流可(ke)調的(de)(de)(de)(de)(de)(de)移(yi)動電(dian)(dian)(dian)(dian)源(yuan)就應運而生。這樣(yang)的(de)(de)(de)(de)(de)(de)移(yi)動電(dian)(dian)(dian)(dian)源(yuan)一(yi)般標配多(duo)個充(chong)電(dian)(dian)(dian)(dian)輸(shu)出(chu)口(kou)，而每個輸(shu)出(chu)口(kou)的(de)(de)(de)(de)(de)(de)輸(shu)出(chu)電(dian)(dian)(dian)(dian)流會在明顯的(de)(de)(de)(de)(de)(de)位(wei)置加以(yi)(yi)標注，比如1A、2A等字樣(yang)，用戶(hu)可(ke)以(yi)(yi)根據自身的(de)(de)(de)(de)(de)(de)實際使用需求來選擇(ze)。另外，還(huan)有一(yi)種單口(kou)輸(shu)出(chu)、多(duo)種電(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)壓可(ke)調的(de)(de)(de)(de)(de)(de)移(yi)動電(dian)(dian)(dian)(dian)源(yuan)，由于此類產品價格高昂、體積龐大、重量也難以(yi)(yi)接受(shou)，普通用戶(hu)在使用中很難碰到(dao)，所(suo)以(yi)(yi)我(wo)們在此一(yi)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(li)電(dian)(dian)(dian)池的(de)(de)充電(dian)(dian)(dian)截止閥(fa)值是以電(dian)(dian)(dian)壓來計算的(de)(de)，用不同電(dian)(dian)(dian)流輸出的(de)(de)插孔(kong)為同一臺手機充電(dian)(dian)(dian)，只會獲得更快的(de)(de)充電(dian)(dian)(dian)速度，對手機其(qi)它部分沒有(you)影(ying)響，更不會損壞(huai)手機。

缺點：唯一不好(hao)(hao)的地方就是，大(da)電(dian)(dian)(dian)流(liu)充電(dian)(dian)(dian)會(hui)帶來較高的熱量，這對于電(dian)(dian)(dian)子(zi)元件的保護、保養是沒有(you)好(hao)(hao)處(chu)的，可(ke)能(neng)會(hui)加速電(dian)(dian)(dian)子(zi)元件的老(lao)化。如(ru)果用(yong)戶不是很有(you)必要用(yong)大(da)電(dian)(dian)(dian)流(liu)對手(shou)機(ji)進行充電(dian)(dian)(dian)的話，我(wo)們還是建(jian)議(yi)按(an)照手(shou)機(ji)說明書(shu)上(shang)要求的額(e)定電(dian)(dian)(dian)流(liu)充電(dian)(dian)(dian)，這樣(yang)來的比較穩妥。

充電寶給手機充電斷開的原因

很(hen)多網友反(fan)映，購買到的(de)(de)充(chong)電(dian)(dian)寶給手機充(chong)電(dian)(dian)時，充(chong)一(yi)會兒就(jiu)斷開(kai)了，這(zhe)種情(qing)況，一(yi)般來說與移動(dong)電(dian)(dian)源的(de)(de)質量有(you)關，主要有(you)如下幾個因(yin)素：

1、充電寶輸出(chu)電(dian)(dian)(dian)壓不夠(gou)。這(zhe)(zhe)是(shi)(shi)根據充電(dian)(dian)(dian)原理(li)決定的，必須是(shi)(shi)高電(dian)(dian)(dian)壓流(liu)向低(di)電(dian)(dian)(dian)壓，手機(ji)一(yi)般是(shi)(shi)3.7V，移動(dong)電(dian)(dian)(dian)源鋰電(dian)(dian)(dian)芯(xin)是(shi)(shi)3.7V，這(zhe)(zhe)樣就是(shi)(shi)平級的，因此移動(dong)電(dian)(dian)(dian)源在輸出(chu)電(dian)(dian)(dian)壓時(shi)，會進行升(sheng)壓到5V，這(zhe)(zhe)樣就產生高電(dian)(dian)(dian)壓流(liu)向低(di)電(dian)(dian)(dian)壓，進行充電(dian)(dian)(dian)。

2、充電(dian)寶輸出電(dian)流強度不(bu)夠。我們在測試(shi)一些移動電(dian)源的(de)(de)時候，上(shang)面標稱有(you)800mAh放(fang)電(dian)，但是有(you)時根本(ben)不(bu)能以這(zhe)個規(gui)格進(jin)行(xing)放(fang)電(dian)，電(dian)流強度不(bu)夠時也會發(fa)生這(zhe)種現象，這(zhe)個和電(dian)壓息息相關，最根本(ben)的(de)(de)還(huan)是鋰電(dian)芯質量(liang)不(bu)好所致。

3、與手機(ji)本身(shen)有關。可(ke)能手機(ji)電阻值過大，其實這種(zhong)情況的可(ke)能性非常少。只是在此提(ti)及。

4、與移動(dong)電(dian)源的(de)PCBA保(bao)護板(ban)有關。在第1點提到(dao)，保(bao)護板(ban)要起到(dao)過流過充過放的(de)功(gong)能，同時(shi)還有一(yi)個(ge)MCU，這個(ge)就(jiu)是用(yong)來升壓，如果保(bao)護板(ban)質量不好，在電(dian)流穿(chuan)過時(shi)就(jiu)不穩定，導至PCBA怠工，然后(hou)導致(zhi)充電(dian)寶無法(fa)充電(dian)，發(fa)生上述(shu)的(de)情況。
