【手(shou)機伴侶充電寶(bao)(bao)】充電寶(bao)(bao)怎么充電 充電寶(bao)(bao)充電時間多久合適
說到移動電源,我們(men)不(bu)得不(bu)引入(ru)充(chong)電(dian)(dian)(dian)(dian)(dian)寶充(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間(jian)這個(ge)概念。這里并不(bu)是指(zhi)移(yi)動電(dian)(dian)(dian)(dian)(dian)源(yuan)對手(shou)機設備的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間(jian),而是電(dian)(dian)(dian)(dian)(dian)源(yuan)給移(yi)動電(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間(jian)。這里有(you)一(yi)個(ge)算(suan)法(fa),用移(yi)動電(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)容量(liang)除以(yi)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流,再除以(yi)一(yi)個(ge)0.8的(de)做功(gong)轉換系數,得出(chu)的(de)時(shi)(shi)(shi)間(jian)基本就是充(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間(jian)了。舉(ju)例來(lai)說,一(yi)個(ge)容量(liang)為5000毫安的(de)移(yi)動電(dian)(dian)(dian)(dian)(dian)源(yuan),用1A的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)器進行充(chong)電(dian)(dian)(dian)(dian)(dian),根據(ju)上面的(de)算(suan)法(fa),大概6個(ge)多小時(shi)(shi)(shi)就可以(yi)充(chong)滿(man)。
在選擇移動電(dian)源(yuan)時,應當注意充電(dian)時間,即(ji)便(bian)是晚上充電(dian)白天使(shi)用的話,如果超過8個(ge)小時,這很難與現(xian)代人的作息(xi)習慣相吻合:早上起來發現(xian)昨晚插上的移動電(dian)源(yuan)竟(jing)然還(huan)在充電(dian),這是讓(rang)人非常不爽的一件事情。
充電寶怎么充電
如(ru)(ru)果是(shi)普通充(chong)手(shou)機之類的數碼產品,那(nei)么(me)普通的1A電(dian)流(liu)(liu)輸出的移動電(dian)源(yuan)已(yi)經完全夠用了,但如(ru)(ru)果要是(shi)充(chong)iPad的話(hua)就需要2A以(yi)上的電(dian)流(liu)(liu)的,否(fou)則即便是(shi)連接上也會顯示該設備不(bu)在充(chong)電(dian),用戶可以(yi)根(gen)據自(zi)己的事(shi)情情況加以(yi)選擇。
1A輸出電流:主(zhu)流的(de)移動電源一般為一個(ge)USB充電插口(kou),而5000毫安甚至以(yi)上即便的(de)產品(pin)會配備(bei)兩個(ge)甚至更(geng)多個(ge)USB接口(kou)。這(zhe)樣做(zuo)最大(da)的(de)好處就(jiu)是可(ke)以(yi)同時給多臺設備(bei)充電,從而達到節省時間的(de)目的(de)。不過,這(zhe)樣做(zuo)也會有弊端(duan),比如(ru)多口(kou)設備(bei)同時工(gong)作的(de)時候,每個(ge)接口(kou)不可(ke)能達到宣稱的(de)電流輸出指標,下降(jiang)是必(bi)須的(de)。這(zhe)就(jiu)對移動電源本身的(de)電路和品(pin)質(zhi)有著較高(gao)的(de)要(yao)求(qiu),用戶(hu)在購買時需要(yao)注意挑選。
可調輸出電(dian)(dian)(dian)流(liu):需(xu)要(yao)注意(yi)(yi)的(de)是,以(yi)(yi)(yi)上所(suo)提到的(de)USB充(chong)電(dian)(dian)(dian)口(kou)輸出電(dian)(dian)(dian)流(liu)基本都是1A,這就意(yi)(yi)味著這樣的(de)移(yi)(yi)(yi)動(dong)電(dian)(dian)(dian)源(yuan)是無法為iPad等(deng)大電(dian)(dian)(dian)流(liu)的(de)產品(pin)充(chong)電(dian)(dian)(dian)的(de),所(suo)以(yi)(yi)(yi)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)可調的(de)移(yi)(yi)(yi)動(dong)電(dian)(dian)(dian)源(yuan)就應運而生。這樣的(de)移(yi)(yi)(yi)動(dong)電(dian)(dian)(dian)源(yuan)一般標(biao)配(pei)多個充(chong)電(dian)(dian)(dian)輸出口(kou),而每個輸出口(kou)的(de)輸出電(dian)(dian)(dian)流(liu)會在(zai)明(ming)顯的(de)位置加以(yi)(yi)(yi)標(biao)注,比如1A、2A等(deng)字(zi)樣,用(yong)戶可以(yi)(yi)(yi)根(gen)據(ju)自身(shen)的(de)實(shi)際使(shi)用(yong)需(xu)求來選擇。另外,還有一種(zhong)單(dan)口(kou)輸出、多種(zhong)電(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)壓可調的(de)移(yi)(yi)(yi)動(dong)電(dian)(dian)(dian)源(yuan),由于此類產品(pin)價格高(gao)昂(ang)、體積(ji)龐大、重(zhong)量也難(nan)(nan)以(yi)(yi)(yi)接受(shou),普(pu)通用(yong)戶在(zai)使(shi)用(yong)中很難(nan)(nan)碰(peng)到,所(suo)以(yi)(yi)(yi)我們在(zai)此一筆帶過。
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)池的充(chong)電(dian)(dian)截止閥值是以電(dian)(dian)壓來(lai)計算的,用(yong)不(bu)同(tong)電(dian)(dian)流輸出的插孔為同(tong)一臺手機(ji)充(chong)電(dian)(dian),只(zhi)會(hui)獲(huo)得更(geng)快的充(chong)電(dian)(dian)速(su)度(du),對手機(ji)其(qi)它部分沒有(you)影響,更(geng)不(bu)會(hui)損(sun)壞手機(ji)。
缺點:唯一不好的(de)(de)地方就是,大電(dian)(dian)流充電(dian)(dian)會(hui)帶來(lai)較高的(de)(de)熱量,這(zhe)對于電(dian)(dian)子(zi)元件(jian)的(de)(de)保(bao)護、保(bao)養是沒有(you)(you)好處的(de)(de),可能(neng)會(hui)加速電(dian)(dian)子(zi)元件(jian)的(de)(de)老(lao)化。如果(guo)用(yong)戶不是很有(you)(you)必要用(yong)大電(dian)(dian)流對手機進行充電(dian)(dian)的(de)(de)話,我們還是建議按照手機說(shuo)明書上要求的(de)(de)額定電(dian)(dian)流充電(dian)(dian),這(zhe)樣來(lai)的(de)(de)比較穩(wen)妥。
充電寶給手機充電斷開的原因
很多網友反映,購買到的充電寶給手機充電時,充一會(hui)兒就斷(duan)開(kai)了,這種情況,一般來說與移動電源的質(zhi)量有(you)關,主(zhu)要有(you)如下幾(ji)個因素:
1、充電寶輸(shu)出(chu)電(dian)(dian)(dian)(dian)壓(ya)不夠(gou)。這(zhe)(zhe)是(shi)根(gen)據(ju)充(chong)電(dian)(dian)(dian)(dian)原理決定的(de),必須(xu)是(shi)高電(dian)(dian)(dian)(dian)壓(ya)流向低(di)電(dian)(dian)(dian)(dian)壓(ya),手機一般是(shi)3.7V,移動電(dian)(dian)(dian)(dian)源鋰電(dian)(dian)(dian)(dian)芯是(shi)3.7V,這(zhe)(zhe)樣就是(shi)平級(ji)的(de),因此移動電(dian)(dian)(dian)(dian)源在(zai)輸(shu)出(chu)電(dian)(dian)(dian)(dian)壓(ya)時,會進行升壓(ya)到5V,這(zhe)(zhe)樣就產生高電(dian)(dian)(dian)(dian)壓(ya)流向低(di)電(dian)(dian)(dian)(dian)壓(ya),進行充(chong)電(dian)(dian)(dian)(dian)。
2、充(chong)電寶輸出電流強(qiang)度(du)不(bu)夠(gou)。我們(men)在(zai)測試(shi)一些(xie)移動電源的(de)(de)時候,上面(mian)標稱有(you)800mAh放電,但是有(you)時根本(ben)(ben)不(bu)能以這(zhe)(zhe)個規格進(jin)行放電,電流強(qiang)度(du)不(bu)夠(gou)時也會發(fa)生這(zhe)(zhe)種現象,這(zhe)(zhe)個和(he)電壓息(xi)息(xi)相關,最(zui)根本(ben)(ben)的(de)(de)還是鋰電芯質量不(bu)好所致。
3、與手(shou)機本身(shen)有(you)關。可能手(shou)機電(dian)阻值(zhi)過大,其實這種情況的可能性非常少。只(zhi)是(shi)在此提及。
4、與移動電(dian)源的PCBA保護板有關。在(zai)第(di)1點(dian)提到,保護板要(yao)起到過流過充過放(fang)的功能(neng),同時還(huan)有一個MCU,這個就是用來升(sheng)壓(ya),如果保護板質量不好(hao),在(zai)電(dian)流穿過時就不穩(wen)定,導至PCBA怠工,然(ran)后導致充電(dian)寶無法充電(dian),發(fa)生上述的情況(kuang)。
