2. 產品亮點  product highlights

2.1                采用2個風扇組合成一個吹風一個抽風方式，形成有效的空氣對流，冷風進去熱風出來的模式，有效的達到散熱效果。

Use two 12V fans forced Push and pull air，cool air in and hot air are draw out， effectively achieve the charger cooling.

2.2                內部單片機控制，分4段式，確保電池在任何狀態下充電合理化，防止過充、欠充、電池化學激烈反應發熱等，有效增長電池壽命.

Internal MCU control ，the charging process have divided four segments ensure protect the battery over charge、under charge and battery chemistry violent reaction heat ，growth the battery life.

2.3                充電器內部單片點亮LED等模式，通過不同充電階段點亮不同的LED燈顏色告知客戶當前的充電狀態，方便客戶使用.

Internal MCU light the LED ，different timer have different LED color to let our user know what is the current status ，facilitate customers.

2.4                客戶需要為主導的安裝AC輸入和DC輸出方式.

Customers dominant the AC input and the  DC output connection.
