壓提升至15V左右(依照負載程度輸出電壓會改變)再供電給馬達,因為坊間5V行動電源輸
出最大電流多在2A,為了避免行動電源超載輸出,所以該塊電路板會將最大取電功率限制
在10W以內,確保行動電源不會超載輸出並提升行動電源的相容性,但馬達輸出功率也會
下降,所以使用5V行動電源供電時大約只有原本四成的輸出功率

且支援12V輸出的話,則可以使用QC觸發器,觸發行動電源輸出12V,並使用隨附的USB-A
轉DC插頭線路插到轉軸後方15V輸入的位置(注意,不可插在原本行動電源5V輸入的位置)
,同樣可以讓風扇啟動運轉,且因為12V供電功率較大,可以讓電風扇運作在插電模式下
七成左右的功率

目前PD行動電源也越來越普及,若行動電源支援15V電壓組合,並支援30W或以上的輸出功
率,同樣可以透過PD觸發器讓行動電源輸出15V,供電給電風扇的15V輸入插座,這樣就可
以讓電風扇在行動電源模式下以額定功率運作

結論:
勳風14吋節能行動立扇,無段式風速調節,集風網罩設計讓風流可以吹更遠,直流無刷馬
達提供六年保固,除了採交流電轉15V供電以外,也具備行動電源供電能力,讓使用場合
及區域範圍可以擴大,不會受到電源插座的限制。行動供電模式為了避免5V行動電源超載
,風扇最大輸出功率會受限,但只要手上有合適裝備的,行動供電模式下也可採12V或15V
輸入,可讓風扇以接近或等同於額定功率運作,價格定位導致整體塑膠感較重,但同樣具
備高低/俯仰調整功能
