2012年諾基亞推(tui)出首(shou)個(ge)支(zhi)持無(wu)(wu)線(xian)充(chong)電(dian)的手(shou)機(ji)(ji)——Lumia 920，三星在(zai)(zai)Galaxy S6手(shou)機(ji)(ji)上(shang)也首(shou)次支(zhi)持無(wu)(wu)線(xian)充(chong)電(dian)。我們可以看(kan)到無(wu)(wu)線(xian)充(chong)電(dian)并不(bu)是什么(me)新(xin)產物，而是一(yi)項(xiang)老技術了，但是無(wu)(wu)線(xian)充(chong)電(dian)真正火(huo)起來(lai)(lai)還(huan)是得(de)益于，2017年蘋果在(zai)(zai)旗艦手(shou)機(ji)(ji)上(shang)采用了無(wu)(wu)線(xian)充(chong)電(dian)技術，在(zai)(zai)蘋果的引領下，其它手(shou)機(ji)(ji)廠商(shang)紛紛跟進，無(wu)(wu)線(xian)充(chong)電(dian)市場迎來(lai)(lai)了爆發。

那么無(wu)線(xian)(xian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)能不(bu)能成為主流(liu)的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)方式呢？我們(men)先來看一下無(wu)線(xian)(xian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)在(zai)實際使用中(zhong)體驗如(ru)何。雖然無(wu)線(xian)(xian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)免除了(le)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)拔插，但是實際上要受制于空間(jian)與距離的(de)限制（離得太遠(yuan)就充(chong)(chong)(chong)(chong)不(bu)了(le)）。而且你在(zai)用無(wu)線(xian)(xian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時，你無(wu)法(fa)自如(ru)的(de)使用手機，所以無(wu)線(xian)(xian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)目前(qian)真談不(bu)上便利。

另外就(jiu)是充(chong)電(dian)效率(lv)，目前有(you)線快(kuai)充(chong)已(yi)經(jing)可以做到30W-40W功率(lv)，甚至有(you)55W的(de)超高快(kuai)充(chong)技術(shu)，相比之下(xia)無線充(chong)電(dian)受(shou)限于現有(you)技術(shu)，功率(lv)普遍較小(xiao)，蘋果目前只有(you)7.5W而已(yi)，無線充(chong)電(dian)的(de)速度(du)遠(yuan)遠(yuan)跟不上主(zhu)流需求;另外在價(jia)格方面，無線充(chong)的(de)價(jia)格也(ye)比有(you)線充(chong)的(de)價(jia)格普遍要(yao)高。

所以充電(dian)器(qi)廠家認為(wei)就(jiu)目(mu)前(qian)(qian)來說(shuo)，無(wu)線(xian)充電(dian)更多(duo)像(xiang)一(yi)種(zhong)時髦的(de)玩具，想要(yao)成為(wei)主流充電(dian)方式還(huan)有(you)很長的(de)一(yi)段路(lu)要(yao)走(zou)，目(mu)前(qian)(qian)還(huan)是(shi)快充的(de)天下。
