@ 小弟託家人買回上面產品,但想請問這太陽能板到底是幾W?

@ 使用這12 Volt Solar Panel Charger+ DC 12V/18W 長型白色燈管燈一展 + 12V 7.2AH 蓄電池或 12V 2AH(充飽電狀態下,在正常日照下使用每日開燈四小時)--- 怎麼只使用兩天就沒電?

@若使用這12 Volt Solar Panel Charger+ DC 12V/18W 長型白色燈管燈一展 + 12V 60AH 車用蓄電池,在正常日照下;此太陽能板是否有能力充足12V 60AH 車用蓄電池?可以增加多少時間?

    1.26W

    當然沒電 那使用每日開燈四小時完全是靠電池放電的

    18W用四ㄍ小時 若以日照充電六小時計算

    你太楊能板大約要有十五瓦才行

    1.2W是.........差太多啦
