1、手(shou)機型(xing)號是否(fou)支持(chi)無(wu)(wu)線充(chong)電(dian)OR無(wu)(wu)線充(chong)電(dian)器是否(fou)匹(pi)配

無線(xian)(xian)充(chong)電(dian)器有時候放上去沒反應，首先要看手(shou)機(ji)型號支不支持，需(xu)不需(xu)要外(wai)加(jia)裝無線(xian)(xian)充(chong)電(dian)線(xian)(xian)圈。

a.手(shou)機(ji)內置無(wu)線(xian)充(chong)(chong)電接(jie)收(shou)端：直接(jie)放(fang)在無(wu)線(xian)充(chong)(chong)電器上就可以(yi)充(chong)(chong)電。

b.手機內部(bu)預留了無線(xian)(xian)充(chong)電接(jie)收端(duan)觸點：需要加(jia)裝無線(xian)(xian)充(chong)電接(jie)收線(xian)(xian)圈實現無線(xian)(xian)充(chong)電的。

c.手機本身完全(quan)不支(zhi)持無線充電，需(xu)要加(jia)裝一(yi)個無線充電接收背架(jia)的(de)實現(xian)無線充電的(de)。

2、無線充(chong)電器指示(shi)燈(deng)是否顯示(shi)正常

其次，有些(xie)品牌的(de)無線充(chong)電(dian)(dian)器周(zhou)圍(wei)有LED燈，當手機放(fang)(fang)在無線充(chong)電(dian)(dian)器上充(chong)電(dian)(dian)時(shi)，無線充(chong)電(dian)(dian)器周(zhou)圍(wei)的(de)LED燈會亮起，或者有的(de)是提示音，顯示使用(yong)狀態。也有的(de)時(shi)候是反應(ying)遲鈍，放(fang)(fang)上去(qu)需要等(deng)幾秒(miao)才充(chong)電(dian)(dian)，有時(shi)還得重放(fang)(fang)。

3、手機保(bao)護殼等無線充電(dian)器(qi)外在影響因素

然后(hou)，請檢(jian)查手(shou)(shou)(shou)機(ji)(ji)是否是背面(mian)中心置(zhi)于無(wu)線充(chong)(chong)電板(ban)中心處，查看手(shou)(shou)(shou)機(ji)(ji)與無(wu)線充(chong)(chong)電板(ban)之間(jian)有夾雜物時，可能(neng)無(wu)法正常充(chong)(chong)電；再檢(jian)查檢(jian)查手(shou)(shou)(shou)機(ji)(ji)后(hou)殼，若(ruo)使用的保護性(xing)手(shou)(shou)(shou)機(ji)(ji)套(tao)(tao)太厚(hou)可能(neng)會阻礙無(wu)線充(chong)(chong)電，建議(yi)拆掉手(shou)(shou)(shou)機(ji)(ji)套(tao)(tao)重新(xin)充(chong)(chong)電嘗試。

4、無(wu)線(xian)充電器正常(chang)工作需要滿足的條件(jian)

最后，無線(xian)(xian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)的發射器(qi)功(gong)率，可能(neng)也(ye)會(hui)導致無線(xian)(xian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)用不(bu)(bu)(bu)了的原因。接(jie)收器(qi)輸出的短路電(dian)(dian)(dian)(dian)流能(neng)達到(dao)1A，實際在充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)只有(you)0.3左右了，插上(shang)手(shou)機(ji)電(dian)(dian)(dian)(dian)壓直接(jie)降到(dao)3.9V了，這(zhe)個電(dian)(dian)(dian)(dian)壓根(gen)本達不(bu)(bu)(bu)到(dao)給手(shou)機(ji)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的額定(ding)電(dian)(dian)(dian)(dian)壓，而且無線(xian)(xian)發射器(qi)的最大(da)工作電(dian)(dian)(dian)(dian)流才600ma，智能(neng)手(shou)機(ji)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)需要700ma~800ma以(yi)上(shang)，所以(yi)無線(xian)(xian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)的發射功(gong)率過小，也(ye)會(hui)使(shi)得充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)充(chong)(chong)(chong)(chong)不(bu)(bu)(bu)進去(qu)。
