手提電風扇,經歷了三代的發展。從第一代的USB風扇,只能用USB供電,不能充電,到第二代的電池風扇,支持可充電電池,卻又不支援手機充電功能,到現在最新的第三代手機充電電風扇,支援可充電電池的同時具備手機充電功能。隨著科技進步和需求增大,一部簡簡單單的手提電風扇也逐漸向多功能化改進,單一功能的迷你電風扇註定被市場淘汰。


一般來說,手提電風扇的外型,尺寸,重量不盡相同,但技術參數大致相同:

產品執行標準:GB4943.1-2011

輸出功率:3.5W-4.5W

額定電壓:5V

輸入電流:0.5-1A

電池容量:2200-2500mAh

額定頻率:50H

供電方式:USB/電池

待機時長:4-8小時

電機:純銅電機

壽命:5年以上


風扇檔位一般2-3檔

扇葉:3-5片

第一檔風力30-40分貝

第二檔風力59分貝

第三檔風力63分貝


這些分貝具體是怎樣的一個環境昵?

0-10分貝:人耳剛剛能聽到聲音

10-20分貝:花開的聲音,手錶轉動的聲音

30分貝:安靜的圖書館

40分貝:一般居室的聲音,蚊子飛過的聲音

45分貝:輕聲細語

50-60分貝:電話鈴聲,辦公室敲鍵盤的聲音
