在給(gei)手機充電(dian)的(de)時候，我(wo)們經常會混(hun)用(yong)一些充電器。在用不同(tong)(tong)的(de)充(chong)(chong)電(dian)器進行充(chong)(chong)電(dian)時(shi)，我(wo)們(men)也(ye)會發現手(shou)機(ji)的(de)充(chong)(chong)電(dian)速度(du)也(ye)會有(you)(you)所不同(tong)(tong)，由此我(wo)們(men)知道，充(chong)(chong)電(dian)器是會影響手(shou)機(ji)的(de)充(chong)(chong)電(dian)速度(du)的(de)。還有(you)(you)人認為(wei)充(chong)(chong)電(dian)器的(de)功率越大，充(chong)(chong)電(dian)的(de)速度(du)也(ye)就越快(kuai)，那么(me)事實真的(de)如此嗎?

事實是(shi)充電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)功率(lv)的大(da)小(xiao)確實會影響(xiang)(xiang)手(shou)機的充電(dian)(dian)(dian)(dian)(dian)(dian)速度(du)，但(dan)是(shi)它對手(shou)機充電(dian)(dian)(dian)(dian)(dian)(dian)速度(du)的影響(xiang)(xiang)是(shi)被控(kong)制在一定范(fan)圍之內的。而這(zhe)個(ge)充電(dian)(dian)(dian)(dian)(dian)(dian)的限額則(ze)是(shi)由手(shou)機電(dian)(dian)(dian)(dian)(dian)(dian)池的保護電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)IC來決定的。比如(ru)手(shou)機的電(dian)(dian)(dian)(dian)(dian)(dian)池把電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)最大(da)限定在2A，那么你即使用(yong)多(duo)大(da)功率(lv)的充電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，它的輸出也不會超過2A，而且如(ru)果(guo)功率(lv)過大(da)甚至還會燒壞電(dian)(dian)(dian)(dian)(dian)(dian)池。

手(shou)機(ji)的電池(chi)不僅控(kong)制著最高的輸出(chu)，還(huan)會(hui)智能的調節充電器的充電速(su)度(du)。如(ru)果你(ni)仔細觀察就會(hui)發現，手(shou)機(ji)電量一般在充到80%以(yi)后，充電的速(su)度(du)就會(hui)慢慢的降(jiang)下(xia)來，這同樣是電池(chi)的一種自我保護(hu)。

雖然充(chong)(chong)電器(qi)功率(lv)(lv)越高(gao)，不代表(biao)充(chong)(chong)電速度就(jiu)越快(kuai)，但是想(xiang)要提高(gao)充(chong)(chong)電速度確實需要大功率(lv)(lv)的(de)充(chong)(chong)電器(qi)。現在的(de)快(kuai)充(chong)(chong)技術流行后，手機(ji)充(chong)(chong)電器(qi)的(de)功率(lv)(lv)也從5W漸(jian)漸(jian)變為12W、18W、22W…越來越高(gao)。弄明(ming)白可這些(xie)以后，你(ni)就(jiu)知(zhi)道充(chong)(chong)電器(qi)比不是功率(lv)(lv)越大越好，合適(shi)才(cai)是最(zui)重要的(de)。
