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usb風扇有(you)很多種,不同(tong)的小(xiao)風扇,電(dian)池容(rong)量也(ye)有(you)所不同(tong),具體要充(chong)(chong)(chong)多久的電(dian)要看(kan)電(dian)池容(rong)量大(da)小(xiao)和充(chong)(chong)(chong)電(dian)器的電(dian)流,一(yi)般電(dian)腦的usb口可(ke)以為外置設(she)備提供電(dian)壓為5伏特電(dian)力(li),500mA電(dian)流,小(xiao)風扇的電(dian)池容(rong)量在1200~2000mAh,充(chong)(chong)(chong)電(dian)時(shi)間大(da)概在1~2小(xiao)時(shi)左(zuo)右;如果是(shi)一(yi)些大(da)容(rong)量的usb風扇,充(chong)(chong)(chong)電(dian)時(shi)間更長。
二、手持電扇怎么看充滿電沒有
現在很(hen)多(duo)usb手持風扇都是可充(chong)電(dian)(dian)的,充(chong)電(dian)(dian)的時候,可以通過看上面的指示(shi)燈狀態判斷有(you)沒(mei)有(you)充(chong)滿電(dian)(dian)。
usb風(feng)扇連接充電時(shi),通常風(feng)扇上(shang)的(de)指示燈會亮,燈亮的(de)話(hua)說明處于(yu)正常充電狀態(tai),如果燈變(bian)(bian)顏色(se)了(比如從紅色(se)變(bian)(bian)綠色(se)),或(huo)者是燈不亮了,說明已經充滿電了。
三、充電小風扇充不上電怎么辦
可(ke)充(chong)電(dian)(dian)(dian)的usb風(feng)扇一般連(lian)接(jie)usb線和電(dian)(dian)(dian)源就可(ke)以充(chong)電(dian)(dian)(dian),除(chu)了電(dian)(dian)(dian)腦主機外,充(chong)電(dian)(dian)(dian)寶之類的也(ye)可(ke)以給它充(chong)電(dian)(dian)(dian),如果充(chong)不上電(dian)(dian)(dian)的話,可(ke)能原(yuan)因(yin)有(you)以下幾(ji)點:
1、接口接觸不(bu)良。
2、充電器故障或(huo)與電池電壓不匹配。
3、電池老化或(huo)損壞。
4、充電接口有異物。
如果遇到usb風扇充(chong)不進電(dian)的情況,可以先(xian)清潔一(yi)下usb風扇的充(chong)電(dian)口(kou),如果還(huan)(huan)是(shi)充(chong)不進電(dian),可以換一(yi)個充(chong)電(dian)口(kou)試(shi)試(shi),還(huan)(huan)是(shi)不行的話,說(shuo)明usb風扇已(yi)經損(sun)壞(huai)了,建議送(song)修或買個新的。
