一、usb風扇充電多久能充滿
usb風扇是通過usb連接線連接電腦使用的,有的usb風扇內置電池,可以充電,那么usb風扇充滿電要多久呢?
市面上的(de)usb風扇(shan)有(you)很多種(zhong),不(bu)同的(de)小(xiao)風扇(shan),電(dian)(dian)(dian)池容(rong)量也有(you)所不(bu)同,具體要(yao)充(chong)(chong)多久的(de)電(dian)(dian)(dian)要(yao)看電(dian)(dian)(dian)池容(rong)量大小(xiao)和(he)充(chong)(chong)電(dian)(dian)(dian)器的(de)電(dian)(dian)(dian)流,一般電(dian)(dian)(dian)腦(nao)的(de)usb口可以為外置(zhi)設備提供電(dian)(dian)(dian)壓為5伏特(te)電(dian)(dian)(dian)力,500mA電(dian)(dian)(dian)流,小(xiao)風扇(shan)的(de)電(dian)(dian)(dian)池容(rong)量在(zai)1200~2000mAh,充(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)(jian)大概在(zai)1~2小(xiao)時(shi)(shi)左右(you);如果是一些大容(rong)量的(de)usb風扇(shan),充(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)(jian)更長。
二、手持電扇怎么看充滿電沒有
現在很(hen)多usb手持風扇都是可(ke)充(chong)電的(de),充(chong)電的(de)時候,可(ke)以通過看上面的(de)指(zhi)示燈狀態判斷有沒(mei)有充(chong)滿電。
usb風扇連接充電(dian)時,通(tong)常風扇上的指示燈會亮,燈亮的話說明(ming)(ming)處于正(zheng)常充電(dian)狀態(tai),如(ru)(ru)果燈變顏色(se)了(比如(ru)(ru)從紅色(se)變綠(lv)色(se)),或(huo)者是燈不亮了,說明(ming)(ming)已經充滿電(dian)了。
三、充電小風扇充不上電怎么辦
可(ke)充(chong)電的usb風(feng)扇一般(ban)連接usb線和電源就可(ke)以(yi)充(chong)電,除(chu)了(le)電腦主(zhu)機外,充(chong)電寶之類(lei)的也可(ke)以(yi)給它(ta)充(chong)電,如果充(chong)不上(shang)電的話,可(ke)能原因有以(yi)下幾點:
1、接口接觸不良(liang)。
2、充電(dian)器故障或與電(dian)池電(dian)壓不匹配。
3、電(dian)池老(lao)化或損壞。
4、充電接口有異物(wu)。
如果遇到usb風扇充不(bu)進(jin)電(dian)(dian)的情況,可(ke)以先(xian)清潔(jie)一(yi)下usb風扇(shan)的充電(dian)(dian)口(kou),如果還(huan)是充不(bu)進(jin)電(dian)(dian),可(ke)以換一(yi)個充電(dian)(dian)口(kou)試(shi)試(shi),還(huan)是不(bu)行的話(hua),說明usb風扇(shan)已經(jing)損(sun)壞了,建議送修或買個新(xin)的。
