市場上，無線充電器的(de)(de)競爭愈演愈烈。與傳統(tong)的(de)(de)有(you)線充電器相(xiang)比，難道它(ta)們就僅(jin)僅(jin)是線纜的(de)(de)區(qu)別嗎？下面我們以(yi)美國的(de)(de)一款無線充電器為例，看(kan)看(kan)它(ta)在(zai)應用上(shang)與普通(tong)有(you)線充電器有(you)著哪些區(qu)別。

差(cha)異一(yi)，充電(dian)(dian)方式(shi)：無線(xian)充電(dian)(dian)器首先(xian)要將(jiang)iPhone裝(zhuang)載進充電(dian)(dian)保護(hu)殼里，然后將(jiang)保護(hu)套放置在感(gan)應底(di)座上，接著(zhu)感(gan)應底(di)座連接電(dian)(dian)源(yuan)插頭(tou)，電(dian)(dian)源(yuan)插頭(tou)再插上電(dian)(dian)源(yuan)。

差異(yi)二(er)，連(lian)(lian)(lian)接(jie)(jie)外(wai)設(she)(she)(she)： iPhone在無線充(chong)電的模式下(xia)連(lian)(lian)(lian)接(jie)(jie)外(wai)設(she)(she)(she)，一是拿出(chu)裝載進充(chong)電保護殼(ke)的iPhone，二(er)是連(lian)(lian)(lian)接(jie)(jie)Mini USB,最后Mini USB連(lian)(lian)(lian)接(jie)(jie)外(wai)設(she)(she)(she)。iPhone在電源轉換器(qi)上(shang)(shang)充(chong)電時只要將USB從轉換器(qi)上(shang)(shang)取出(chu)再連(lian)(lian)(lian)接(jie)(jie)外(wai)設(she)(she)(she)完成了。

差異三，便(bian)利性：當手(shou)機充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時有電(dian)(dian)(dian)話(hua)(hua)進來但是又不方便(bian)在(zai)一些(xie)特定(ding)的(de)(de)情景(jing)下接(jie)聽。這時候(hou)無線(xian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器便(bian)利就(jiu)體現出來了(le)。只需將充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)保護套拿起就(jiu)可以(yi)移(yi)動到任(ren)何用戶方便(bian)接(jie)聽電(dian)(dian)(dian)話(hua)(hua)的(de)(de)地方。如果是有線(xian)的(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器，就(jiu)需要(yao)拔掉數據線(xian)，連接(jie)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)需要(yao)再次插上(shang)數據線(xian)，這個時候(hou)無線(xian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器只需要(yao)將手(shou)機放(fang)置在(zai)感應器上(shang)就(jiu)可以(yi)進行充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)了(le)。

差異四，充電效率：在充電時間相同的情況下，常用的有線電池充電器充(chong)電(dian)(dian)(dian)(dian)后(hou)的電(dian)(dian)(dian)(dian)量為93%，無(wu)線充(chong)電(dian)(dian)(dian)(dian)器充(chong)電(dian)(dian)(dian)(dian)后(hou)的電(dian)(dian)(dian)(dian)量為88%。顯然，無(wu)線充(chong)電(dian)(dian)(dian)(dian)器在(zai)(zai)充(chong)電(dian)(dian)(dian)(dian)效(xiao)率上還存在(zai)(zai)著差距，在(zai)(zai)技術上還有進一步改進的空間。

    隨著技術的不斷革新與改進，手機電池充電器廠將會內置感應充電卡，不用再裝載保護套就能直接充電，再加上充電效率的提高，無線充電器大展拳腳之(zhi)時指(zhi)日可待。
