This design is primarily centered around a charger set. A prominent, central opening in the phone serves two functions: holding the phone and charging it. On one hand, ETNA is mounted on an adapter that plugs directly into a power outlet; the phone charges via induction and lights up, while a color-coded ring on the adapter indicates the charging status. On the other hand, the phone can be hung on a mobile charging adapter, providing a permanent place for the phone within an apartment or office. With this charger set, ETNA can easily integrate into daily routines and workflows.
