在給手機充電(dian)的時候，我(wo)們經常會混用一些充電(dian)器。在用(yong)不同(tong)的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)器進行充(chong)(chong)電(dian)(dian)(dian)(dian)時，我(wo)們(men)也(ye)會發(fa)現(xian)手機的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)速(su)(su)度(du)也(ye)會有所(suo)不同(tong)，由此我(wo)們(men)知道，充(chong)(chong)電(dian)(dian)(dian)(dian)器是會影(ying)響手機的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)速(su)(su)度(du)的(de)。還(huan)有人認(ren)為充(chong)(chong)電(dian)(dian)(dian)(dian)器的(de)功(gong)率越大，充(chong)(chong)電(dian)(dian)(dian)(dian)的(de)速(su)(su)度(du)也(ye)就越快(kuai)，那(nei)么事實真的(de)如(ru)此嗎?

事實是(shi)(shi)(shi)充電(dian)器功(gong)率(lv)的(de)(de)大小確實會(hui)影響(xiang)(xiang)手(shou)機的(de)(de)充電(dian)速度(du)，但(dan)是(shi)(shi)(shi)它對(dui)手(shou)機充電(dian)速度(du)的(de)(de)影響(xiang)(xiang)是(shi)(shi)(shi)被控制在一定(ding)范圍之內的(de)(de)。而這(zhe)個充電(dian)的(de)(de)限額則是(shi)(shi)(shi)由(you)手(shou)機電(dian)池的(de)(de)保護電(dian)路(lu)IC來決定(ding)的(de)(de)。比如手(shou)機的(de)(de)電(dian)池把電(dian)流最大限定(ding)在2A，那么(me)你(ni)即使(shi)用多(duo)大功(gong)率(lv)的(de)(de)充電(dian)器，它的(de)(de)輸(shu)出也不會(hui)超過(guo)2A，而且如果功(gong)率(lv)過(guo)大甚至還會(hui)燒(shao)壞電(dian)池。

手(shou)機(ji)的(de)(de)(de)(de)電(dian)(dian)(dian)池不僅控(kong)制著(zhu)最高的(de)(de)(de)(de)輸(shu)出，還會智能的(de)(de)(de)(de)調節充(chong)(chong)(chong)電(dian)(dian)(dian)器的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)速(su)(su)度。如果你仔細觀察(cha)就會發現(xian)，手(shou)機(ji)電(dian)(dian)(dian)量一般在(zai)充(chong)(chong)(chong)到80%以后(hou)，充(chong)(chong)(chong)電(dian)(dian)(dian)的(de)(de)(de)(de)速(su)(su)度就會慢慢的(de)(de)(de)(de)降(jiang)下來，這同樣是電(dian)(dian)(dian)池的(de)(de)(de)(de)一種自我保護(hu)。

雖然充(chong)電(dian)(dian)(dian)器(qi)功(gong)率(lv)(lv)越(yue)(yue)(yue)(yue)高，不代表(biao)充(chong)電(dian)(dian)(dian)速(su)度就越(yue)(yue)(yue)(yue)快(kuai)，但(dan)是想要(yao)提高充(chong)電(dian)(dian)(dian)速(su)度確實需要(yao)大功(gong)率(lv)(lv)的充(chong)電(dian)(dian)(dian)器(qi)。現在的快(kuai)充(chong)技術流行后，手(shou)機充(chong)電(dian)(dian)(dian)器(qi)的功(gong)率(lv)(lv)也從5W漸(jian)漸(jian)變為12W、18W、22W…越(yue)(yue)(yue)(yue)來越(yue)(yue)(yue)(yue)高。弄明白(bai)可這些以(yi)后，你就知(zhi)道充(chong)電(dian)(dian)(dian)器(qi)比不是功(gong)率(lv)(lv)越(yue)(yue)(yue)(yue)大越(yue)(yue)(yue)(yue)好，合適才是最重要(yao)的。
