1、手機(ji)型號是(shi)否支持無線(xian)充電(dian)OR無線(xian)充電(dian)器是(shi)否匹配

無(wu)線充電(dian)器有時候(hou)放上(shang)去沒反應，首先(xian)要(yao)(yao)看手機型號支不支持，需(xu)不需(xu)要(yao)(yao)外(wai)加(jia)裝無(wu)線充電(dian)線圈。

a.手機內置無線(xian)充(chong)(chong)電(dian)接(jie)收端：直接(jie)放在無線(xian)充(chong)(chong)電(dian)器上就可以充(chong)(chong)電(dian)。

b.手(shou)機(ji)內部預(yu)留(liu)了(le)無線(xian)充(chong)電(dian)接收端(duan)觸點：需要加裝無線(xian)充(chong)電(dian)接收線(xian)圈實現無線(xian)充(chong)電(dian)的。

c.手(shou)機本身完全(quan)不支持無(wu)(wu)線充(chong)(chong)電，需要加裝(zhuang)一個(ge)無(wu)(wu)線充(chong)(chong)電接收背架的實現無(wu)(wu)線充(chong)(chong)電的。

2、無線(xian)充電器指示(shi)(shi)燈(deng)是(shi)否顯示(shi)(shi)正常

其(qi)次，有(you)些品牌的(de)無線(xian)充(chong)電(dian)器周圍(wei)(wei)有(you)LED燈(deng)，當(dang)手(shou)機放在(zai)無線(xian)充(chong)電(dian)器上充(chong)電(dian)時，無線(xian)充(chong)電(dian)器周圍(wei)(wei)的(de)LED燈(deng)會亮起，或者有(you)的(de)是提示音，顯示使用(yong)狀態。也(ye)有(you)的(de)時候是反應遲鈍，放上去需(xu)要等(deng)幾秒才充(chong)電(dian)，有(you)時還得重放。

3、手機保護殼等無線充(chong)電(dian)器外(wai)在(zai)影響因素

然后，請(qing)檢查(cha)手(shou)(shou)機(ji)是否是背面中(zhong)心置(zhi)于無線充電(dian)板(ban)中(zhong)心處，查(cha)看手(shou)(shou)機(ji)與無線充電(dian)板(ban)之間有夾(jia)雜物時，可(ke)能無法正常充電(dian)；再檢查(cha)檢查(cha)手(shou)(shou)機(ji)后殼，若(ruo)使(shi)用的保護性手(shou)(shou)機(ji)套太厚可(ke)能會阻礙無線充電(dian)，建(jian)議拆(chai)掉手(shou)(shou)機(ji)套重新充電(dian)嘗試。

4、無線充電器正(zheng)常(chang)工作(zuo)需要(yao)滿(man)足(zu)的條件

最后，無(wu)(wu)線(xian)充(chong)電(dian)(dian)(dian)(dian)器的發(fa)射器功率(lv)，可能也(ye)會導致無(wu)(wu)線(xian)充(chong)電(dian)(dian)(dian)(dian)用不了的原因。接(jie)收器輸(shu)出的短路電(dian)(dian)(dian)(dian)流能達到1A，實際(ji)在充(chong)電(dian)(dian)(dian)(dian)時(shi)只(zhi)有(you)0.3左右(you)了，插上(shang)手機電(dian)(dian)(dian)(dian)壓直接(jie)降到3.9V了，這個電(dian)(dian)(dian)(dian)壓根本達不到給手機充(chong)電(dian)(dian)(dian)(dian)的額定電(dian)(dian)(dian)(dian)壓，而且無(wu)(wu)線(xian)發(fa)射器的最大工作電(dian)(dian)(dian)(dian)流才(cai)600ma，智能手機充(chong)電(dian)(dian)(dian)(dian)需要700ma~800ma以上(shang)，所以無(wu)(wu)線(xian)充(chong)電(dian)(dian)(dian)(dian)器的發(fa)射功率(lv)過小，也(ye)會使得充(chong)電(dian)(dian)(dian)(dian)充(chong)不進(jin)去。
