I don't know where the wall outlets are.

我都找不到墙上的电源插座了。

Plugging in a charger draws the electricity from a wall outlet that drives the reaction to regenerate the metal, making more electrons available for oxidation the next time you need them.

接通充电器能够引入墙壁插座中的电流，这一反应可以恢复金属的供电能力，当你下次需要的时候会有更多电子参与氧化反应。
