【手機伴(ban)侶充(chong)電(dian)寶】充(chong)電(dian)寶怎(zen)么充(chong)電(dian) 充(chong)電(dian)寶充(chong)電(dian)時(shi)間多(duo)久(jiu)合適
說到移動電源,我們不(bu)得(de)不(bu)引入(ru)充(chong)電(dian)(dian)(dian)寶充(chong)電(dian)(dian)(dian)時間這個概(gai)(gai)念。這里并(bing)不(bu)是(shi)指移動電(dian)(dian)(dian)源(yuan)(yuan)對手機設備的(de)充(chong)電(dian)(dian)(dian)時間,而是(shi)電(dian)(dian)(dian)源(yuan)(yuan)給移動電(dian)(dian)(dian)源(yuan)(yuan)的(de)充(chong)電(dian)(dian)(dian)時間。這里有一(yi)個算(suan)法(fa),用(yong)移動電(dian)(dian)(dian)源(yuan)(yuan)的(de)容量(liang)除以(yi)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流,再除以(yi)一(yi)個0.8的(de)做功轉換系數,得(de)出(chu)的(de)時間基(ji)本就是(shi)充(chong)電(dian)(dian)(dian)時間了(le)。舉例來說,一(yi)個容量(liang)為(wei)5000毫安的(de)移動電(dian)(dian)(dian)源(yuan)(yuan),用(yong)1A的(de)充(chong)電(dian)(dian)(dian)器進行充(chong)電(dian)(dian)(dian),根據上面(mian)的(de)算(suan)法(fa),大概(gai)(gai)6個多小時就可(ke)以(yi)充(chong)滿。
在選擇移動電源(yuan)時(shi),應當注意充(chong)電時(shi)間,即便是晚(wan)上(shang)充(chong)電白天使用(yong)的(de)話,如果超過8個小(xiao)時(shi),這很難(nan)與現代人的(de)作(zuo)息習慣相吻合:早上(shang)起來發(fa)現昨晚(wan)插上(shang)的(de)移動電源(yuan)竟然還在充(chong)電,這是讓人非常不爽(shuang)的(de)一件(jian)事(shi)情。
充電寶怎么充電
如(ru)果是(shi)普(pu)通充手機(ji)之類的數碼產品(pin),那么普(pu)通的1A電(dian)流(liu)輸出的移動(dong)電(dian)源已經(jing)完全夠用(yong)了,但(dan)如(ru)果要是(shi)充iPad的話就(jiu)需要2A以上(shang)的電(dian)流(liu)的,否則(ze)即便是(shi)連接上(shang)也會顯示該設(she)備不在(zai)充電(dian),用(yong)戶(hu)可以根據自(zi)己的事情(qing)情(qing)況加以選擇。
1A輸(shu)出(chu)電(dian)(dian)(dian)流(liu):主流(liu)的(de)移(yi)動(dong)電(dian)(dian)(dian)源(yuan)一般為一個(ge)(ge)USB充電(dian)(dian)(dian)插口(kou)(kou),而(er)5000毫安(an)甚至以上即便的(de)產品(pin)會(hui)配備兩(liang)個(ge)(ge)甚至更(geng)多(duo)個(ge)(ge)USB接口(kou)(kou)。這樣做最大的(de)好(hao)處就(jiu)是可以同時(shi)(shi)給多(duo)臺設備充電(dian)(dian)(dian),從(cong)而(er)達到節省(sheng)時(shi)(shi)間的(de)目的(de)。不過,這樣做也會(hui)有(you)弊端,比(bi)如多(duo)口(kou)(kou)設備同時(shi)(shi)工作的(de)時(shi)(shi)候,每個(ge)(ge)接口(kou)(kou)不可能達到宣稱的(de)電(dian)(dian)(dian)流(liu)輸(shu)出(chu)指標,下降是必(bi)須(xu)的(de)。這就(jiu)對移(yi)動(dong)電(dian)(dian)(dian)源(yuan)本身的(de)電(dian)(dian)(dian)路和(he)品(pin)質有(you)著較(jiao)高的(de)要(yao)求,用戶(hu)在購買時(shi)(shi)需要(yao)注(zhu)意挑選(xuan)。
可(ke)調(diao)(diao)輸(shu)(shu)出電(dian)(dian)(dian)流(liu)(liu):需(xu)要注意的是,以上所(suo)提到的USB充電(dian)(dian)(dian)口(kou)輸(shu)(shu)出電(dian)(dian)(dian)流(liu)(liu)基(ji)本都是1A,這就意味著(zhu)這樣的移(yi)(yi)(yi)動電(dian)(dian)(dian)源(yuan)(yuan)是無(wu)法為iPad等(deng)大電(dian)(dian)(dian)流(liu)(liu)的產品充電(dian)(dian)(dian)的,所(suo)以充電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)可(ke)調(diao)(diao)的移(yi)(yi)(yi)動電(dian)(dian)(dian)源(yuan)(yuan)就應(ying)運而生。這樣的移(yi)(yi)(yi)動電(dian)(dian)(dian)源(yuan)(yuan)一般標(biao)配多(duo)個充電(dian)(dian)(dian)輸(shu)(shu)出口(kou),而每個輸(shu)(shu)出口(kou)的輸(shu)(shu)出電(dian)(dian)(dian)流(liu)(liu)會在(zai)(zai)明顯(xian)的位置加以標(biao)注,比如1A、2A等(deng)字樣,用(yong)(yong)(yong)戶(hu)可(ke)以根據自身(shen)的實(shi)際使用(yong)(yong)(yong)需(xu)求來選擇。另外,還有(you)一種(zhong)單口(kou)輸(shu)(shu)出、多(duo)種(zhong)電(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)壓可(ke)調(diao)(diao)的移(yi)(yi)(yi)動電(dian)(dian)(dian)源(yuan)(yuan),由于(yu)此類(lei)產品價(jia)格高昂(ang)、體積龐大、重量也(ye)難(nan)以接受,普通(tong)用(yong)(yong)(yong)戶(hu)在(zai)(zai)使用(yong)(yong)(yong)中很難(nan)碰到,所(suo)以我(wo)們在(zai)(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(dian):鋰電(dian)池(chi)的充電(dian)截止閥(fa)值是以(yi)電(dian)壓來計算的,用(yong)不同電(dian)流輸出的插(cha)孔為同一臺手機充電(dian),只(zhi)會獲得更快的充電(dian)速(su)度(du),對(dui)手機其它(ta)部分沒有(you)影響,更不會損壞手機。
缺點:唯一(yi)不好(hao)的(de)(de)(de)地方就是,大電(dian)(dian)流(liu)充電(dian)(dian)會(hui)帶來較高的(de)(de)(de)熱(re)量,這對(dui)于電(dian)(dian)子元(yuan)(yuan)件的(de)(de)(de)保護、保養是沒有好(hao)處的(de)(de)(de),可(ke)能會(hui)加(jia)速電(dian)(dian)子元(yuan)(yuan)件的(de)(de)(de)老化(hua)。如果用戶不是很有必要(yao)用大電(dian)(dian)流(liu)對(dui)手機(ji)進(jin)行充電(dian)(dian)的(de)(de)(de)話,我們還是建議按照手機(ji)說明書上要(yao)求的(de)(de)(de)額定電(dian)(dian)流(liu)充電(dian)(dian),這樣來的(de)(de)(de)比(bi)較穩妥。
充電寶給手機充電斷開的原因
很多網友反映,購(gou)買到(dao)的充電寶給手機充電時,充一會兒就(jiu)斷(duan)開了,這(zhe)種情(qing)況,一般來說與移動(dong)電源(yuan)的質量(liang)有關,主要有如下幾個(ge)因素:
1、充電寶輸出電(dian)(dian)壓不夠(gou)。這是(shi)根(gen)據(ju)充電(dian)(dian)原理決(jue)定的,必須是(shi)高(gao)電(dian)(dian)壓流向低電(dian)(dian)壓,手機(ji)一般是(shi)3.7V,移(yi)動(dong)電(dian)(dian)源鋰(li)電(dian)(dian)芯是(shi)3.7V,這樣就是(shi)平級的,因(yin)此移(yi)動(dong)電(dian)(dian)源在輸出電(dian)(dian)壓時(shi),會進行(xing)升壓到5V,這樣就產生高(gao)電(dian)(dian)壓流向低電(dian)(dian)壓,進行(xing)充電(dian)(dian)。
2、充電(dian)(dian)寶輸出電(dian)(dian)流強度(du)不夠。我們在測試(shi)一些移動(dong)電(dian)(dian)源的時(shi)候,上面(mian)標稱有(you)800mAh放電(dian)(dian),但是(shi)有(you)時(shi)根本不能以(yi)這個(ge)規格進行(xing)放電(dian)(dian),電(dian)(dian)流強度(du)不夠時(shi)也會發生(sheng)這種現象,這個(ge)和電(dian)(dian)壓息息相關,最根本的還是(shi)鋰電(dian)(dian)芯質量不好所致。
3、與手(shou)機本身有關。可能手(shou)機電阻值過(guo)大,其實這種(zhong)情況(kuang)的可能性非常(chang)少。只是在此提及。
4、與移動電源(yuan)的PCBA保(bao)護板(ban)有(you)關。在第1點(dian)提到(dao)(dao),保(bao)護板(ban)要(yao)起到(dao)(dao)過(guo)流過(guo)充過(guo)放的功能,同時還有(you)一(yi)個MCU,這個就是(shi)用來升壓(ya),如果保(bao)護板(ban)質(zhi)量(liang)不好,在電流穿過(guo)時就不穩定,導至PCBA怠工(gong),然后導致充電寶無法充電,發(fa)生上述的情(qing)況。
