【手機伴侶充電(dian)寶】充電(dian)寶怎么(me)充電(dian) 充電(dian)寶充電(dian)時間多久合適
說到移動電源,我(wo)們不得(de)不引入充(chong)電(dian)(dian)(dian)寶(bao)充(chong)電(dian)(dian)(dian)時間(jian)(jian)(jian)這(zhe)個(ge)概念。這(zhe)里(li)并不是指移動(dong)電(dian)(dian)(dian)源(yuan)對手機(ji)設備的(de)(de)(de)充(chong)電(dian)(dian)(dian)時間(jian)(jian)(jian),而是電(dian)(dian)(dian)源(yuan)給(gei)移動(dong)電(dian)(dian)(dian)源(yuan)的(de)(de)(de)充(chong)電(dian)(dian)(dian)時間(jian)(jian)(jian)。這(zhe)里(li)有一(yi)個(ge)算法,用(yong)移動(dong)電(dian)(dian)(dian)源(yuan)的(de)(de)(de)容量除(chu)以(yi)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流,再(zai)除(chu)以(yi)一(yi)個(ge)0.8的(de)(de)(de)做功(gong)轉換系數,得(de)出的(de)(de)(de)時間(jian)(jian)(jian)基本就(jiu)是充(chong)電(dian)(dian)(dian)時間(jian)(jian)(jian)了。舉例來說,一(yi)個(ge)容量為(wei)5000毫安的(de)(de)(de)移動(dong)電(dian)(dian)(dian)源(yuan),用(yong)1A的(de)(de)(de)充(chong)電(dian)(dian)(dian)器進(jin)行充(chong)電(dian)(dian)(dian),根(gen)據上面(mian)的(de)(de)(de)算法,大概6個(ge)多小時就(jiu)可以(yi)充(chong)滿。
在(zai)選擇移(yi)動(dong)電源時,應當(dang)注意充電時間(jian),即便是(shi)晚上充電白(bai)天使用(yong)的(de)話,如果超(chao)過8個小時,這(zhe)很難與現代(dai)人的(de)作息(xi)習(xi)慣(guan)相吻合:早上起來發現昨晚插(cha)上的(de)移(yi)動(dong)電源竟然還(huan)在(zai)充電,這(zhe)是(shi)讓人非常不爽的(de)一(yi)件事(shi)情。
充電寶怎么充電
如(ru)(ru)果是(shi)普(pu)通充(chong)手機之類的(de)(de)數(shu)碼產品,那么普(pu)通的(de)(de)1A電(dian)流(liu)輸出的(de)(de)移動電(dian)源(yuan)已經完(wan)全夠用(yong)了,但如(ru)(ru)果要是(shi)充(chong)iPad的(de)(de)話就需要2A以上的(de)(de)電(dian)流(liu)的(de)(de),否則即便是(shi)連接上也會(hui)顯示(shi)該設(she)備(bei)不(bu)在充(chong)電(dian),用(yong)戶(hu)可以根據(ju)自己的(de)(de)事情(qing)情(qing)況加以選擇。
1A輸出電(dian)(dian)(dian)流(liu):主流(liu)的(de)(de)移(yi)動(dong)電(dian)(dian)(dian)源(yuan)一般(ban)為一個(ge)(ge)USB充電(dian)(dian)(dian)插(cha)口(kou),而5000毫安(an)甚(shen)(shen)至以上即(ji)便(bian)的(de)(de)產品(pin)會(hui)(hui)配(pei)備兩個(ge)(ge)甚(shen)(shen)至更(geng)多(duo)個(ge)(ge)USB接口(kou)。這樣做最大的(de)(de)好處就(jiu)是可以同(tong)(tong)時給多(duo)臺設(she)備充電(dian)(dian)(dian),從而達(da)(da)到節(jie)省時間的(de)(de)目(mu)的(de)(de)。不過,這樣做也會(hui)(hui)有弊(bi)端(duan),比如多(duo)口(kou)設(she)備同(tong)(tong)時工作的(de)(de)時候,每個(ge)(ge)接口(kou)不可能達(da)(da)到宣稱的(de)(de)電(dian)(dian)(dian)流(liu)輸出指標,下降是必須的(de)(de)。這就(jiu)對(dui)移(yi)動(dong)電(dian)(dian)(dian)源(yuan)本身(shen)的(de)(de)電(dian)(dian)(dian)路(lu)和品(pin)質有著較高的(de)(de)要求,用戶在購買時需要注意挑(tiao)選(xuan)。
可(ke)調輸(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu):需(xu)要(yao)注(zhu)意的(de)(de)(de)是,以(yi)上所(suo)(suo)提到的(de)(de)(de)USB充(chong)電(dian)(dian)(dian)(dian)口輸(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)基本都是1A,這就(jiu)意味(wei)著(zhu)這樣的(de)(de)(de)移(yi)動電(dian)(dian)(dian)(dian)源(yuan)是無法為iPad等(deng)大電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)(de)產品(pin)(pin)充(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de),所(suo)(suo)以(yi)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)可(ke)調的(de)(de)(de)移(yi)動電(dian)(dian)(dian)(dian)源(yuan)就(jiu)應運(yun)而生。這樣的(de)(de)(de)移(yi)動電(dian)(dian)(dian)(dian)源(yuan)一(yi)般標配(pei)多個(ge)充(chong)電(dian)(dian)(dian)(dian)輸(shu)出(chu)(chu)口,而每(mei)個(ge)輸(shu)出(chu)(chu)口的(de)(de)(de)輸(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)會在(zai)明顯的(de)(de)(de)位置加以(yi)標注(zhu),比如(ru)1A、2A等(deng)字樣,用(yong)戶可(ke)以(yi)根據自身的(de)(de)(de)實際使用(yong)需(xu)求(qiu)來選擇。另外(wai),還(huan)有(you)一(yi)種(zhong)(zhong)單口輸(shu)出(chu)(chu)、多種(zhong)(zhong)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓可(ke)調的(de)(de)(de)移(yi)動電(dian)(dian)(dian)(dian)源(yuan),由于此(ci)類產品(pin)(pin)價格高昂、體(ti)積龐大、重量也(ye)難以(yi)接(jie)受,普通用(yong)戶在(zai)使用(yong)中(zhong)很難碰到,所(suo)(suo)以(yi)我(wo)們在(zai)此(ci)一(yi)筆帶過(guo)。
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)池的充電(dian)截止閥值是以電(dian)壓來計算的,用不同電(dian)流輸(shu)出的插孔為同一(yi)臺手機(ji)(ji)充電(dian),只會獲得更快的充電(dian)速度,對(dui)手機(ji)(ji)其它(ta)部分(fen)沒有影響,更不會損(sun)壞手機(ji)(ji)。
缺點:唯(wei)一不好的(de)(de)地方(fang)就(jiu)是,大電(dian)流(liu)充(chong)(chong)電(dian)會帶來(lai)較(jiao)高的(de)(de)熱量(liang),這(zhe)對(dui)于電(dian)子(zi)元(yuan)件的(de)(de)保(bao)護、保(bao)養是沒有(you)好處的(de)(de),可(ke)能會加(jia)速電(dian)子(zi)元(yuan)件的(de)(de)老(lao)化。如(ru)果用(yong)戶(hu)不是很(hen)有(you)必要用(yong)大電(dian)流(liu)對(dui)手(shou)機(ji)進行充(chong)(chong)電(dian)的(de)(de)話,我們還是建(jian)議(yi)按照手(shou)機(ji)說明書(shu)上要求的(de)(de)額定電(dian)流(liu)充(chong)(chong)電(dian),這(zhe)樣來(lai)的(de)(de)比較(jiao)穩妥。
充電寶給手機充電斷開的原因
很(hen)多網友反映,購買到(dao)的(de)充(chong)電寶給手機(ji)充(chong)電時,充(chong)一會兒就斷開了(le),這種情況(kuang),一般來(lai)說與移動電源的(de)質量有關,主要(yao)有如下(xia)幾(ji)個因素:
1、充電寶輸出電(dian)(dian)(dian)壓(ya)不夠。這是(shi)(shi)根(gen)據充(chong)電(dian)(dian)(dian)原理決定(ding)的,必須是(shi)(shi)高(gao)電(dian)(dian)(dian)壓(ya)流向低(di)(di)電(dian)(dian)(dian)壓(ya),手機一般是(shi)(shi)3.7V,移動電(dian)(dian)(dian)源(yuan)(yuan)鋰電(dian)(dian)(dian)芯(xin)是(shi)(shi)3.7V,這樣就(jiu)是(shi)(shi)平(ping)級的,因(yin)此移動電(dian)(dian)(dian)源(yuan)(yuan)在(zai)輸出電(dian)(dian)(dian)壓(ya)時,會(hui)進行升(sheng)壓(ya)到(dao)5V,這樣就(jiu)產(chan)生高(gao)電(dian)(dian)(dian)壓(ya)流向低(di)(di)電(dian)(dian)(dian)壓(ya),進行充(chong)電(dian)(dian)(dian)。
2、充電寶輸出(chu)電流(liu)強度(du)不夠。我們(men)在測試一些移動電源的時(shi)候,上面標稱有800mAh放電,但(dan)是有時(shi)根(gen)本不能以這個(ge)(ge)規格進行放電,電流(liu)強度(du)不夠時(shi)也會發生這種(zhong)現象,這個(ge)(ge)和電壓(ya)息息相關(guan),最根(gen)本的還(huan)是鋰電芯質量不好所致。
3、與(yu)手機(ji)(ji)本身有關。可能手機(ji)(ji)電阻值(zhi)過大(da),其實(shi)這種情(qing)況(kuang)的可能性非(fei)常(chang)少(shao)。只是在(zai)此提及(ji)。
4、與移動電源(yuan)的(de)PCBA保(bao)護板有(you)(you)關。在第1點提到(dao),保(bao)護板要起(qi)到(dao)過(guo)流過(guo)充過(guo)放(fang)的(de)功能(neng),同時還(huan)有(you)(you)一個(ge)MCU,這個(ge)就是(shi)用來升壓(ya),如(ru)果保(bao)護板質量(liang)不好,在電流穿過(guo)時就不穩定,導至PCBA怠工,然后(hou)導致充電寶無法充電,發(fa)生(sheng)上述的(de)情況(kuang)。
