手機、平板沒電(dian)了，但是身邊卻沒有帶(dai)應對(dui)的怎(zen)么辦？這(zhe)個(ge)時候許多(duo)朋友會(hui)找身邊朋友的手機充(chong)電(dian)(dian)器或者其它設備的電(dian)(dian)源適配器來替代充(chong)電(dian)(dian)。那么這(zhe)樣做到底安(an)(an)全不安(an)(an)全呢？這(zhe)樣(yang)會損壞平板電(dian)腦硬件(jian)設備或者出現(xian)適配器爆炸等現(xian)象(xiang)嗎(ma)？相信許(xu)多朋友都很關心這(zhe)個問題，今天飛天鷹科技(ji)就(jiu)來講一講吧。

通常情況(kuang)下，不同的輸(shu)出電(dian)壓設備是(shi)絕對不能(neng)混用適(shi)配(pei)器(qi)的，這一(yi)(yi)點一(yi)(yi)定要注意。而如(ru)果同樣(yang)標(biao)稱5V電(dian)壓的電(dian)源(yuan)適(shi)配(pei)器(qi)，輸(shu)出電(dian)流不同。使用的基(ji)本原則是(shi)大(da)標(biao)稱電(dian)流電(dian)源(yuan)可以代替小標(biao)稱電(dian)流的電(dian)源(yuan)。例如(ru)我們經常會用ipad適(shi)配(pei)器(qi)給(gei)Iphone充電(dian)，甚至(zhi)還發現這樣(yang)充電(dian)還更快些(xie)。

很多(duo)用戶會覺(jue)得大(da)標(biao)稱電(dian)(dian)(dian)流(liu)的(de)(de)(de)電(dian)(dian)(dian)源(yuan)會燒壞主機，因為電(dian)(dian)(dian)流(liu)過(guo)大(da)了。但實際上，電(dian)(dian)(dian)流(liu)多(duo)大(da)在電(dian)(dian)(dian)壓相(xiang)同的(de)(de)(de)情況下取決于(yu)負載，也就是平(ping)(ping)板電(dian)(dian)(dian)腦的(de)(de)(de)工作情況，當平(ping)(ping)板電(dian)(dian)(dian)腦高(gao)負荷運(yun)轉的(de)(de)(de)時(shi)候，電(dian)(dian)(dian)流(liu)增(zeng)大(da)，而等(deng)平(ping)(ping)板進入待機的(de)(de)(de)時(shi)候，電(dian)(dian)(dian)流(liu)就小些。大(da)標(biao)稱電(dian)(dian)(dian)流(liu)的(de)(de)(de)電(dian)(dian)(dian)源(yuan)有足夠的(de)(de)(de)電(dian)(dian)(dian)流(liu)余(yu)量，不(bu)會在代替(ti)小標(biao)稱電(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)源(yuan)之后發生(sheng)過(guo)熱或者(zhe)輸出(chu)電(dian)(dian)(dian)壓過(guo)低的(de)(de)(de)情況。

反問(wen)，小(xiao)電(dian)(dian)流(liu)(liu)電(dian)(dian)源適(shi)配器(qi)可(ke)以為大電(dian)(dian)流(liu)(liu)輸(shu)入(ru)嗎？對于一(yi)(yi)些有過(guo)(guo)載保護的設備來說這樣充也是沒問(wen)題的，不過(guo)(guo)飛天鷹科(ke)技建議小(xiao)電(dian)(dian)流(liu)(liu)電(dian)(dian)源適(shi)配器(qi)最(zui)好不要給大電(dian)(dian)流(liu)(liu)輸(shu)入(ru)，一(yi)(yi)方面(mian)充電(dian)(dian)速度受影響，另一(yi)(yi)方面(mian)這樣做也可(ke)能會出現過(guo)(guo)載現象，導致適(shi)配器(qi)無法正常工作。
