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)(de)usb風扇(shan)(shan)有(you)很多種,不同(tong)的(de)(de)小風扇(shan)(shan),電(dian)(dian)(dian)(dian)池(chi)(chi)容(rong)量(liang)也有(you)所(suo)不同(tong),具體要充(chong)多久的(de)(de)電(dian)(dian)(dian)(dian)要看電(dian)(dian)(dian)(dian)池(chi)(chi)容(rong)量(liang)大(da)小和充(chong)電(dian)(dian)(dian)(dian)器的(de)(de)電(dian)(dian)(dian)(dian)流,一般電(dian)(dian)(dian)(dian)腦的(de)(de)usb口可以為(wei)外置設(she)備(bei)提供電(dian)(dian)(dian)(dian)壓為(wei)5伏(fu)特電(dian)(dian)(dian)(dian)力,500mA電(dian)(dian)(dian)(dian)流,小風扇(shan)(shan)的(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)容(rong)量(liang)在(zai)1200~2000mAh,充(chong)電(dian)(dian)(dian)(dian)時間(jian)大(da)概在(zai)1~2小時左右(you);如果是一些(xie)大(da)容(rong)量(liang)的(de)(de)usb風扇(shan)(shan),充(chong)電(dian)(dian)(dian)(dian)時間(jian)更(geng)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(dou)是可充電(dian)的(de),充電(dian)的(de)時候,可以通過(guo)看上面的(de)指(zhi)示(shi)燈狀態判斷有沒有充滿電(dian)。
usb風(feng)扇連(lian)接充電時,通常風(feng)扇上的(de)指示燈(deng)會(hui)亮(liang)(liang),燈(deng)亮(liang)(liang)的(de)話說明處于正常充電狀態,如果燈(deng)變顏色(se)了(比如從紅色(se)變綠色(se)),或(huo)者是燈(deng)不亮(liang)(liang)了,說明已經充滿(man)電了。
三、充電小風扇充不上電怎么辦
可(ke)充(chong)(chong)(chong)電(dian)(dian)的(de)usb風扇一般連接usb線和(he)電(dian)(dian)源就可(ke)以充(chong)(chong)(chong)電(dian)(dian),除了電(dian)(dian)腦(nao)主(zhu)機外,充(chong)(chong)(chong)電(dian)(dian)寶(bao)之類的(de)也(ye)可(ke)以給它充(chong)(chong)(chong)電(dian)(dian),如果充(chong)(chong)(chong)不上電(dian)(dian)的(de)話(hua),可(ke)能(neng)原因有以下幾點:
1、接(jie)口接(jie)觸不良(liang)。
2、充電器故障(zhang)或(huo)與(yu)電池(chi)電壓不匹配。
3、電池老化(hua)或損壞。
4、充電(dian)接口(kou)有異物。
如果遇到usb風扇充不進(jin)電的情況,可以(yi)先清(qing)潔(jie)一(yi)下usb風(feng)扇(shan)的充電口,如果(guo)還是(shi)充不進(jin)電,可以(yi)換一(yi)個(ge)充電口試試,還是(shi)不行的話,說(shuo)明usb風(feng)扇(shan)已經(jing)損(sun)壞了,建議送(song)修或買個(ge)新的。
