There are two 1,430mAh battery cells inside of the
iPhone 11 Pro Max version of the Smart Battery Case,
up from the 1,369mAh battery cells used last year
in the iPhone XS Max Smart Battery Case.
The two battery cells are wired together into one battery,
allowing the cases to offer 10.9Wh of energy
(vs. 10.1Wh in the prior XS Max model).
iPhone 11 Pro Max 電池殼裡面有兩顆 1,430mAh 10.9Wh 的電池，
去年 XS Max 是 1,369mAh 10.1Wh。

常跑戶外或旅遊的人或拍長影片的人可以考慮這產品，
或是電池老化後除了換電池，也有一個選擇(但屆時可能斷貨)。
iPhone 11 Pro Max 電池總容量為 3969mAh 15.04Wh，
電池殼裡面有兩顆 1,430mAh 的電池，應該能延長不少使用時間。
